TERMS: Classes of Public Watar Systems Public water systems are generally classified into two categories as follows: iii Group A—serving 15 or more connections or 25 ox more people/day for 60 or more days/,year. Group B —serving less than 15 connections (but more than one single family residence) and less than 25 people for 60 days or rnore/year or less tha,n. 15 connections and any number or people for less than 60 days/�ear. A full description of the classes of systems is contained in WAC 246-290-010. Designated Purveyor or A water purveyor (utility) identified to provide water Designated Utility service to a given area. When willing to provide tha servica in a timely and reasonable �nanner, the designated purveyor is assigned an exclusive right to provide public water service to the area and is required to include the area within.its a�proved Water System Plan. Expanding Water Systems Those public water systems installing additions, extensions, changes, or alterations to their existing source, transmission, storage, or distribution facilities which will enable the system to increase in size its existing service area and/or increase its number of approved service connections. New individual retail or direct service connections onto an existing distribution systam shall not be considered an expansion of the public water system. Fire Flow For design purposes, it is the rate of water delivery needed for the sole purpose of fighting fires. The fire flow volume shall be in addition to the requireme�ts of the water system for domestic demand, and a 20 psi residual pressure should be maintained throughout the system under combzned maxirx�um. derrzand flow conditions. �ranchise A.rea Non-exclusive area in which a utility is penmitted by the County to e�tend facilities in public rights-o� way. A franchise area is not eqt�ivalei�t to a service area. Interlocal Agreement See Service.A.rea Agreement AV IntezCie A physical connection between individual wat�r systems which allows water supply to be transferred in one or both directions. An intertie can be established as a primary source, secondary or peaking supply, or emergency supply, Ordinarily, the use of an intertie is governed by a written agreement or contract betw�en utilities. A modification to water rights issued by Ecology may also be r�quired. Land Use Designation The land use(s) allowed in a geographical axea by right or permit, as provided in the Grant County Comprehensive Plan and Zoning Ordinanae. Lavel of Service Operational features, such as pressure, flow, reliability, etc., provided to the customer by the water system, New Construction Any addition of supply, transmission, distribution or storage facilities, either in a new water systern or an expanding water system, which provides a capability to serve additional dwelling units or other buildings. Public Water System Any system, excluding a system serving only one single-family residence and a system.with four or fewer connection.s all of which sazv�residences on. the same farm, providing piped water for huznan. consumption, including any: a. Ca�leation, treatment, storage, or distribution facilities under control of the purvayor and used primarily in connection with such system; and b. Collection or pretreatment storage facilzties not under control of the purveyor primarily used in connection with such system. Remote System A public water system, located within the designated servic� area of a utility, that is detached from the primary facilities of the utilit}y. A rem.ote systern has its own source of sup�ly. Satellite System A public water system, located within that portion of the Critical Water Supply Service Area not designated as a contiguous service area for any existing utility. Multiple satellite systems znay be owned andlor operated by a single utility without necessit�of�hysical connection between systems. v Designated Service Area A geographical area assigned to a water purveyor for the purpose of providing both current and future public water sezvice. Boundaries are defined by agraements among adj acent utilities and are recorded on a set of maps on file with Grant County Health District. Water service provided within designated service areas must be consistent with. lo�al land use densities, and (if applicable) an approved Wa,ter System Plan. Service Area Agreement An agreement signed by water utilities which identifies the service area for which the utility has retail water service xesponsibility. Service Connection A physical connection through.which water znay be delivered to a customer for discretionary use. Unless � otherwise indicated, all such connections, wheth�r currently in use or not, shall be considered as a service connection. The service connection de�nes the limit of the water utility's responsibility for system dasign and operation unless otherwise provided for in the water utility's condition of service policies. Utility customers such as mobile home parks, planned unit developrzlents, condominiums, apartment buildings, industriaUcommercial sites, or other s}milar complexes are generally considered exterior to the water system. In such cases, the purveyor shall be required to meet design standards for water systems up to the point of service to the customer; and beyond that point, the applicable plumbing and building codes, fire codes, County health regulations, and local ordinarzces are deemed to be sufficient to protect the�ubizc health and xo ensure adequate water service. These customers are not themselves considered harein as water puzveyors unless specifically designated as such b�DOH. Water System Plan A written plan prepared for a particular watex systenn and service area which identifies a schedule of needed improvements, a financial pragram, and an operations program. A water syste:m which is expanding within a designated service area may be required to include other elements in its plan.

SUMMARY 1. INTRODUCTION This update of the Grant County Critical Water Supply Service Area(CWSSA) Coordinated Water System Plan (CWSP) is the result of a team effort by the Water Utility Coordinating Commititee (WUCC) to meet the public drinking water supply needs of the CWSSA. The revision was prompted in part by the Growth Management Act (GMA) which necessitates utilities to properly plan for their provision of service. During a period of several months, bimonthly meetings were held to review draft segments of the CWSP and direct revisions as needed. This CWSP update is a local and State management program developed pursuant to Chapter 70.116 RCW and WAC 246-293. This CWSP update is particularly significant in that it represents a cooperative effort between Grant County, the Cities of Moses Lake, Ephrata, Warden, Quincy, Soap Lake, George, individual water utilities, and the State Department of Health. The CWSP update provides a process and strategy for the existing water utilities to define their role in a program to meet the adoptad land use and projected growth strategy of the area. The CWSP reprasents the collective views of the WUCC and integrates the views of other State and local governrnents. The original plan adopted by the Grant County Commissioners in 1982 focused heavily upon issues of water resources. Although this update includes information developed through the initial process the focus of this revised plan has''been placed on coordination, consistency, and the process for development proposals requiring public water service. 2. OBJECTIVES Beyond the statutory requirements, the following objectives were established and ernphasized during the development of the Coordinated Water System Plan. The Coordinated Water System Plan shall: A. Be established an,d utilized by water utilities as the framework for providing utility service to future growth within the CWSSA; B. Establish uniform proceduz'es for the review and approval of all water service for new development, while discouraging the proliferation of new public water systems in designated service areas within the CWSSA; C. Ensure that the policies and procedures of the CWSP complement the policies regulating land use; I-1 i I , D. Identify service areas of responsibility for water utilities which will improv�thair planning and management abilities; E. Address failing water systems; and F. Provide a system that will minimize unnecessary County administrative procedures. 3. FINDINGS AND RECOMMENDATIONS The WUCC fin.dings and recommendations presented by the CWSP are listed below. It is xecommended that; A. Management Area The CWSP update specifically provides plans for the provision of public water supply in tha CWSSA. The area is divided into designated service areas and unclaimed areas. The CWSP update and the Public Water System Coordination Act assign responsibility for planning, designing, financing, constructing, and operating all public water systems to the d�signated purveyor in the designated sezvice areas. B. Water Supply and Land Use The CWSP update has incorporated the land use and projected development program of the Cities, and the County to the degree that they have been documented. It is anticipated that thE CWSP will be amended as tihe GMA and land and resource management plans are further evaluated, considered, and adopted through normal updating procedures. C. Deszgnated Service Area The designated service areas represent the geographical area where the identified utility has accepted responsibility to provide a safe and reliable water supply in a timely and reasonable manner. The service area boundaries established by the individual utilities, as identified on official county GIS maps, shall be recognized as the final service area designations. Copies of these boundaries shall also be submitted to DOH for their use in raview�of water system plans, construction documents, and proj ect reports. D. Receivership of Failing Systems Existing State law provides for the County to be the "receiver of last resort" of water systems that are unable to comply with the federal and State regulations. The County is identified as the receiver of a failed water system.in the event that n.o I-2 other person is willing and able to take on the system. The CWSP provides for water systems to adopt a policy regarding water system receivership in their water system plan. E. Minimum Design Standards The Minimum Design Standards developed by the WIJCC will be appliec�to all Group A systems throughout the CWSSA, If the levels of service adopted within: the Grant County Comprehensive land use plan are more stringent then those within the CWSP, then the CWSP will need to be revised to zneet those standards. F. Appeals Process The Appeals process develo�ed by the WUCC will be applied when a disagreement arises over "timely and reasonable" water service. The Appeals Process allows for informal discussions trying to resolve the disagreements before a formal appeal hearing. The Appeals Process is further described in Section V. G. Regional issues The CWSP addresses regional issues within the CWSSA such as Wellhead Protection, Water Rights, Water Consezvation, a Leak Detection Program, and Shared Facilities. Within the CWSSA, there is the opportunity �or water utilities to benefit from shared facilities (interties) and from a coordinated leak detection program. H. Administrative Framework Implementation of the CWSP requires participation by all members of the WUCC. Since the CWSP, after adoption by the County and DOH, becomes the CWSSA public water supply plan, a11 related decisions by local and State government will be guided by the plan. The Utility Service Review Procedure (USRP), Section V, represents how the County anticipates administering their responsibilities. One or more Satellite System Management Agencies may become rasponsible for unclaimed axeas. The water utilities wzll be responsible for updating their water system plans for their designated areas in accordance with DOH regulations. I. Plan Implementation The following identifies the primary requirements for implementing the CWSP upclate. I-3 1. Once approved by the WLTCC, the Coordinated Water System Plan shall be reviewed and endorsed by the Grant County Commissioners and submitted to DOH for approval. 2. Quarterly meetings of the WUCC shall be scheduled the first year to review CWSP update implementation. The frequency of ineetings in subsequent years shall then be established based upon need,but at least annual meetings should be held. 3. All Group A water utilities shall complete their Service Area Agreement and submit it to the Grant County Health District prior to the effective date of the CWSP. Approval of proposed expansion or improvements to those utilities not having submitted their Service Area Agreement, and/or building�ermits for new construction to be served by the utility, shall be withheld until the Agreement is submitted, although exceptions may be made for public health and safety. For a utility to expand, the Service Area Agreement must be consistent with their Water System Plan. � 4. The rninimum design standards should be reviewed annually by the WUCC Technical Subcornmittee. Recommended revisions to the minim.um design standards shall be submitted to the WUCC and then to the County :For adoption. 5. The objectives and procedures outlined in the CWSP ar� considered to be reasonable and achievable by all properly operated water systems. Repeated failure by a system to provide safe, reliable and minimum levels of water service, shall serve as a basis to eva�uate viability of the system. Non-viable systems may be candidates for,xeceivership, voluntary transfer of ownership, or merger proceedings. 6. The CWSP shall be updated and revised when the State Department of Health, the County, or the Water Utilit� Coordinating Committee requires an update. I-4 � ' Sec�ion II THE COORDINATED WATER SYSTEM PLAN PROCESS 1. INTRODUCTION In 1977 the Washington State Legislature enacted the Public Water System Coordination Act, RCW 70.116, which established a procedure for the State's water utilities to coordinate their planning and construction programs with adjacent water utilities and other local governmental activities. The law specifies that either tha Department of Health (DOH) or the County Commissioners may declaxe an area within a County as a Critical Water Supply Service Area (CWSSA). This declaration is based upon the findings of a Preliminar�Assessment identifying an area as having problems related to inadequate water quality, unreliable service, or lack of coordinated planning. Implementation of the Coordination Act requires that a Coordinated Water System Plan (CWSP) be prepared for the study area. The first Coordinated Water System Plan was prepared for that portion of Grant County lcnown as the Quincy Groundwater Subarea in 1982. Part of the revision of this project included evaluating the axternal boundaries of the Critical Water Supply Service Area. The external boundary was modified to include the City of Warden. This CWSP u�date, has been prepared in accordance with the requirements of RCW 70.116 and WAC 246-293. It consists of a compilation of water sys�em plans prepared by each expanding utility and municipally owned system, and this document. 2. BACKGROUND , A. Prior Planning Activities An evaluation of concerns related to water system growth and development was first initiated in January 1977 by water utilities within the Moses Lake area. Their primary interest at that time was limited to solving domestic water suppl�issues such as the proliferation of small inadaquate public water systems, iznproved area utility planning, arid resolving future water rights issues. Until the Public Water System Coordinatian Act was enacted later in 1977, these utilities were limited in their ability to pursue legally binding solutions other than through the water right reservation process, WAC 173-590. However, in June 1977, the Moses Lake axea utilities began to pursue reseivation and coordination efforts by preparation of a Coordinated Water System Plan. At the request �f the Grant County Cot�missioners and the Moses Lake area utilities, a preliminary assessment was prepared in November 1978. �ased upon the results of that preliminary assess:ment, the County Coznmissioners declared a Critical Water Supply Service Area (CWSSA) in the Moses Lake area in January II-1 � 1979. The balance of that year was spent in informational meetings and in establishing the external CWSSA boundaries. Because the nature of problems established in the Moses Lake preliminaiy assessment related to operational, procedural, planning, and water resource probleins that had potential impact throughout the Quincy Groundwater Subarea (QGSA), the County Commissioners authorized that a preliminary assessment be conducted for the entire QGSA to establish the extent of the problem and the potential benefit from implementing the Public Water Systenn Coordination Act throughout the QGSA. This preliminary assessment, completed on June 12, 1980, concluded that utility size, system facilities, existing problems, an.d fuxure water resource availability concerns of systen:is throughout the QGSA were very sixnilar. Therefore, the QGSA preliminazy assessment was prepared as an addendum to �ha Moses Lake assessment. This assessment identified the problems which were commonly found throughout the QGSA. As a result of the �ndings, the Grant County Commissioners declared the Quincy Groundwater Subarea as a Critical Water Supply Service.Area on June 16, 1980. Therefore the development of a Coordinated Water System Plan has been developad for the entire area. By 1998, the need to update the Plan was identified that would focus on coordination, consistency, and the process for development proposals. It was recommended that an amended plan be prepared which placed emphasis on the following topics: � Setting minimum design standards. • Establishing designated service areas. . s Establishing a uniform procedure for the review and approval of all water service for new development, while discouraging the proliferation of new public water systems within designated service areas. • Identifying an appeals process for the coordinated water system plan. � Address failing water systems. • Developing a strategy for coordinated system development between the Cities and the other public water systerns within the CWSSA. 3. CWSP PREPARATION The revised CWSP invalved the joint efforts of participating WUCC members, DOH, and City and County staff to identify designated utility service areas, develop minimum design standards, identify procedures �or the review and approval of new developments requirin,g public water facilities, and evaluate the GCHD's role in providing sup�ort services to existing purveyors. �'art of the revision of the CWSP raquired evaluating the External Boundaries of the CWSSA. The boundaries were modified to include the City of Warden. (See Exhibit II-1, Resolution No. 98-168-CC) The following areas received particular emphasis during preparation.of the CWSP. II-2 A. Designated Service Areas Each utility was requested through correspondence, and during WtJCC meetings, to identify its designated service area boundaries on a map. The designated service area consists of a utility's combined existing and future service area. All public water syskems were contacted by 1Ptter, requesting identification of their proposed designated service areas. The designated service area boundaries of the Group A systems with intent to expand were implemented into the Grant County Health District Geographical Information System (GIS) maps. Utilities that did not identify their designated sezvice area were assurned not to be interested in expanding. A Service Area Agreement was developed to allow utilities to document and commit to providing service in geographical areas as defined by boundaries shown on the GIS maps. A designated Service Area is not valid for system expansion unless it is consistent with a DOH approved Water System Plan. A more thorough description of'the manner for establishing utility service areas is described in Section III. B, Minimum Design Standards This subj ect included a diverse list of considerations by the utilities including: material specifications, construction practices, utility location, distribution facilities, metered services, fire-flow requirements, etc. The contents and application of these standards were developed jointly through input of WUCC representatives and the County. ,; The development of these minimurn design standards and their content is presented in Section IV. When accepted and adopted by the County and approved by DOH, they will become the minirnum standards for new Group A public water systems and expansions of existing Group A public water systems. C. Utility Service Review Procedure The USRP was developed to identify the appropriate purveyor to provide water service to new developments and axpansions. This procedure utilizes the recognized designated service areas as a basis for assigning new applicants for development permits and new water system�roposals to water utilities. In unc�aimed areas, the procedure emphasizes adjacent utilities with an. appxoved water system.plan as the preferred service providers. If designated and adjacent utilities are not available, the Grant County Health District will refer a developer to one or more approved Satellite JVlanagement Agencies. These changes were incorporated for utility service review that is outlined in Section V. The USRP applies to all Group A and Group B public water systems. II-3 D. Individual Water System Plans The Public Water System Coordination Act states that each purveyor within the External Boundary shall be responsible for completion of a water system plan for the purveyor's designated service area. Elements of the water system plan are to be based upon twenty-year planning period, with identification of specific improvements and a financial program for the first six years. The purveyor is to update the plan at least every sxx years. However, DOH may require a plan submission or update at any time. An exception to this criteria exists for non.- municipally owned public water systems that existed prior to September 21, 1977 and hava met minimum State Board of Health requirements but do not plan to expand. 4. REGIONAL SUPPLEMENT This plan has been prepared under the provisions of WAC 246-293-220 which allows for a CWSP which consists of: 1) a compilation of water system plans approved by DOH, and 2) a Regional Supplement (this document) which addresses water purveyor concerns relating to the entire CWSSA. All completed water system plans of the individual utilities will be kept on file at the State Department of Health. All Group A water systems were invited to participate in the CWSP update, and Table IT-1 lists those systems with fifty or more permanent connections and also those smaller systems which have indicated an intent to ex�and their service arEa. This table serves a number of purposes incltiding the following: A. Identifies for each participating utility its degree of compliance with the plaru�ing requirements of the CWSP. ; B. Directs Grant County and DOH attention to those utilities which must satisfy WSP and CWSP planning requirements before system improvement and/or expansion of service takes place. To assure a high degree of�lan compliance, the CWSP requires that: • Al� water utilities who have not done so, shall immediately complete and file Service Area Agreamants with the Grant Count�Health District. • Unless a documented public health e;mergency exists, failure to file a Service Area Agreement consistent with their Water System Plan will result in denial of proposed system expansions within the designated service area. The Grant County Health District shall be responsible for updating th:e service area maps and Table II-1. II-4 The Regional Supplement has been completed and is represented by the document contained herain. The compilation of individual water plans indicate that many utilities must prepare or update their plans, WAC 246-293-290 enables DOH to approve portions of the CWSP found to be consistent wzth adopted plans and policies.

BACKGROLIND Designated service areas were established for public water utilities in the 1982 Grant Count� Coordinated Water System Plan. As part of this update of the CWSP, the Water Utility Coordinating Committee reviewed the designated service areas, and made adjustments based on current conditions. The Public Water System Coordination Act provides that a procedure be established to identify the designated service areas of public water utilities within tha Critical Water Supply Service Area(CWSSA). It also specifies that these designated service areas rnusti be developed in conformance with the land use policies of the County and other appropriate governmental bodies. Two obligations accompany the establishment of designated service area boundaries. First, the County and State governments recognize each utility as tha responsible agency for providing all public water supply service within its designated service area. Second, is the utility's responsibilit� for planning and implementing water system development and proper utility management within their designated service area. If a new public water system is developed, then they will need to fulfill trie proper planning requirements. WAC 246-293-190 provides a legal mechanism, for municipalities and private water utilities alike, to establish a designated service area within unincorporated areas within the CWSSA. This provision of the Act proves to be mutually beneficial to utilities, developers, and the County. If a new public water system is developed, it shall have approved water system planning documents, and will require the establishment of new and/or revised designated service area agreements. Designated service areas will impart an assignment of responsibility for efficient utility service to accommodate the future ,growth that these areas will experience in accordanca with the County's Com�rehensiva Plan. Water service may be provided by the designated utility either through direct connection to the utility's existing water system or as a detached, remote system managed by the utility. In either case, the utility shall identify for the applicarit all o�the conditions of service which must be agreed to prior to the provision ot'water service. The Coordination Act requires that the utility be willing to provide service in a tiznely and reasonable manner. (See Timely and Reasonable in Section V) A utility may receive a request for service within its designated service area but may not be able to provide service in a timaly manner. If this occurs, intarim o�erating services by an adjacent utility may be allowed, providing the utility to whom the designated area is assigned is the responsible owner of the system. Service may be provided either through physical connection to an adjacent utility's systern or installation of a detached, III-1 remote system. Although, service area adjustments are not required for provision of interim services, temporary service area agreements must be developed and submitted to the County. Within the CWSSA, over 80 water utilities were invited to identify their designated service area boundaries. All Group A water systezns were asked to identify their desired service areas. Due to their small size, Group B water supply systems were not asked xo select service areas. They are, however, involved in the review process as specified i� Section V. Once the CWSP is adopted by the County, it will assure that the designated servzce area will be legally recognized for each specific utility. This legal recognition has b�en incorporated into the Utility Service Review Procedure outlined in Section V. These designated service area boundaries shall also be submitted to DOH for recognition as the final service area designation. 2. SERVICE AREA SELECTTON PROCESS A. Service Area Selection Procedures The procedure for establishing service area boundaries involved allowing each utility to preliminary indicate those areas they were currently serving or anticipated serving in the �uture. The WiJCC followed a series of procedural steps that resulted in the identification of existing and proposed designated service area bounda�ies for individual systams. The official designated service area maps are incorporated into the CWSP by reference and are on file at the GrantCounty Health District. Copies of the maps can be obtained through the GCHD. B. Designated Service Areas Based on WAC 246-293-250 each Group A public water supply system was given an opportunity to identify their future plans and to identify geographical areas in which they planned to provide water service. Each Group A watez'system was requested to submit a copy of their designated water service area. When water utilities were unable to turn in a service area map, the utility representative was contacted, and the exterior boundaries wera mapped using a Global Positioning System (GPS). The boundaries were then downloaded into the GIS. Utilities will not be allowed to expand until they have; ` 1) Submitted their designated service area maps; 2) Signed a Service Area Agreement; and , 3) Their service areas axe consistent with current and DOH approved Water System Plan. III-2 i The Act provides that following the establishment of the External Boundaiy, no new water systems can be established within a designated service area unless an existing water utility with responsibility in the specified service area is unable or unwillin�to provide service. 3. SERVICE AREA CONFLICTS The CWSP process requires the WUCC to identify conflicting service areas, All conflicts that arise are negotiated between the affected utilities. WAC 246-293-250 states that if service area disputes are not resolved, DOH shall conduct a public hearing in regard to the unresolved service area conflict. At the termination of the hearing, the DOH may impose a moratorium on new water service extensions to the "Contested Service Area" pending resolution of that conflict. There appears to be no conflicting sarvice areas at this time. 4. SERVICE AREA AGREEMENT In order to provide written verification that each water utility had reviewed and endorsed their designated service area, as shown on the set of official GCHD maps, each utility was asked to subxnit an Service Area Agreement which specified the utility's designated service area boundaries. The Service Area Agreement was wz-itten so that each utility verifies its own border. The Service Axea Agreement identifies a proceduxe to coordinate service along boundary alignments between adj acent utilities. An e�ample o:f this standard agreement which was used is shown in Exhibit III-1. To confirm designated service areas and establish their legal service boundary, all expanding water utilities must complete the Service Area Agreement and submit it to the Grant County Health District. Each Service Area Agreement shall be reviewed in conjunction with individual water system plans to assure consistency. Approval of proposad expansion or improvements to those utilities not having submitted their Service Area Agreement andlor building permits for new construction served by the utility shall be withheld until the Service Area Agreement is submitted. Exceptions may be made in public health and safety emergencies b�DOH. After the Service Area Agreemen.ts have been adopted as a part of the indivzdual Water System Plans by DOH, changes in boundary alignment and in the Agreement require a mutual action by the involved water utilities as specified in section 5, below. The completed Sezvice Area Agreements are on file at the Grant County Health District. 5. ESTABLISHMENT OF SERVICE AREAS FOR NEW UTILITIES The creation of new water utilities within or adjacent to existing designated utilities will be discouraged. However, as detailed in Section V, a new utility rnay be created zf one of several service alternatives are not possible. These alternatives will normally involve III-3 the assumption of ownership and operation of the proposed water facilities by an existing utility, an adjacent qualified utility, or ownership or operation by a Satellite Management Agency. 6. UNCLAIMED AREAS Areas that are not covered by any utilities designated service area are considered Unclaimed service areas. These areas may however, be included within one or more Satellite Management Agencies service areas. 7. SERVICE AREA BOIJNDARY CHANGE PROCEDURE Changes in utility service area boundaries may occur when a utility wishes to expand or reduce its service area. Adjustment in service area boundaries cannot be made if a confliat in sezvice areas is created by the modification. Grant County Health DistriGt will maintain and incorporate all approved boundary changes on the GCHD's afficial GIS service area maps. Step 1. The water utility requesting the service area boundary amendment shall submit their request in writing to GCHD along with a map identifying the existing and requested boundaries. The written request shall specify the reason or justification for the change. The GCHD will compare the proposed boundary change with the utility's DOH WSP for consistency, and to verify it does not create a service area conflict with adjacent utilities. 5tep 2. If the requested boundaries are not consistent with DOH WSP, the GCHD will direct the utility requesting a service area change to DOH for modifications in.their Water System Plans. , Step 3. A revised Service Area Agreement will be submitted to the affected utilities for their review, signature, and return to GCHD. Ste� 4. The official GCHD GIS maps are updated. All adjustments in the CWSP External Boundary shall be approved by the County Commissioners. These boundaries shall be reviewed every five years and can be revised at that time or eaxlier, if required. III-4 Service Area Agreement for Establishing Water Utility Service Area Boundaries in the Grant County Critical Water Supply Service Area The authority for this Service.Area Agreement is granted b�the Public Water System Coordination Act of 1977, Chapter 70.116 RCW. WHEREAS, Such an Agreement is required in WAC 246-293-250, Service Area Agreeznents—Requirement, of the Public Water System Coordination Act; WHEREAS, Designation of water service areas, together with the cooperation of utilities, will help assure that time, effort, and money are best used by avoiding unnecessary duplication of service, and; WHEREAS, Definite future service areas consistent with the Growth Management Act (GMA) will facilitate efficient plaruiing for, and provision of, water system improvements within the Critical Water Supply Service .Area (CWSSA) as growth permitted by GMA occurs, and; WHEREAS, Definite water utility planning areas will help assure that water reserved for public water supply purposes within the CWSSA will be utilized in the future in an efficiently planned maru�.er, NOW, THEREFORE, the undersigned party, having entered into this Service A.rea Agreement by signature of its authorized z'epresentative, concurs witl� and will abide by the following provisions: , 1. Sezvice Area Boundaries. The undersigned party acknowledges that the Service Area Map, included as Attachment A to this Service Area Agreement and as may be subsequently updated, accurately identifies the utility's designated servzce area. This signed Service Area Agreement verifies that there are no identified service area conflicts with the adjacent utilities. Boundarv Streets. Existing water lines along boundary streets shall be used to service future development on the same side of the street as the water 1ine. 2. Boundary Adj,tistments. If, at some time in the future, it is in the best interest of the undersigned party to make service area boundary adjustments, such modifications must have the written.cancurrence of all involved parties and proper legislative authority(ies), in conjunction with the Service Area Boundary Change Procedure as identified in Section I�Z of the CWSP, be consistent with the utility's Water System P�an, and rrzust be noted and filed with the Grant County Health District and the State Departznent of Health. If the undersigned is required to have a Urban Growth.Area(LTGA) under the Growth Management Act, then any time the Urban Growth Area (UGA) of the undersigned is adjusted, the service area of the undersigned will need to be adjusted to conform to the revised UGA where applicable. Approval ot'�an adjustment of the service area shall be provided in the CWSP. In the event of a conflict with another utility subject to this CWSP, the conflict shall be resolved as provided for by law and in the CWSP. 3. Service Extension Policies. The undersigned party agrees that prior to expanding its water service area it shall have adopted; 1) Minimum design standards defined in Section IV of the CWSP and, 2) Construction specifications in their water system plan (if already approved by DOH) or, be reviewed and approved by DOH. General purpose local governments will provide service consistent with the levels of servica defined in its development regulatior�s and consistent with its capital facilities plan. Satellite Management Agencies shall provide service at the level required for the location of each water systern owned and or operated by the Satellite Management Agency. This shall be in conformance with construction specx�cations of the utility's water system plan, and applicable land use policies. 5. Svstems Placed in Receivership. RCW 43.70.195 enacted in the 1990 Regular Session of the Washington State Legislature provides that whenever an action is brought in superior court to place a public water system in receivership, the petition to the court shall narne candidates for receiver who have consented�-to assum,e operation of the water system. The undersigned water utility agrees to review and consider water system receivership of failing water systems within its designated service area. By this consent, the undersigned does not waive its rights to appear and participate in the court proceedings to determine acceptable conditions of receivership. This agreement by reference includes the following attachments: Attachment A—Grant County Critical Water Supply Service Area Map. Attachment B —Optional—Utility may attach copies or list such agreements as are relevant. IN WITNESS WHEREOF, the undersigned party has executed this Service Area Agreement.

INTRODUCTION n It is recognized, both in the Public Water System Coordination Act and in the waterworks industry, that standardized design and performance criteria are useful tools in the construction and operation of water utilities. Establishing these minimum ariteria levels �nhances a uniform and satisfactory le�el of utility service enabling hydraulic compatibility between adjacent utilities at minimum additional expense. A technical subcommittee was appointed by the Water Utility Coordinating Committee (WUCC) to develop a draft of the minimum design standards for water utilities within the Quincy Groundwater Subarea. Representatives from the City of Ephrata, City of Moses Lake, Lakeview Park Water Association, and Pelican Point Water Company were on the technical subcommittee. Also contributing to the development and review process were representatives of the County fire districts and Planning Departm.ents. The minimum design standards apply to all new systems and new water line extensions for public Group A community (15 or more connections) water systems within the Quincy Groundwater Subarea in Grant County. Retroactive application of the standards is limited to their incoiporation into systern plans to upgrade existing facilities. The contents of these standards are consistent with the m.inimum. design standards of the Department of Health (DOH). In addition, they conform to the standards of the Standard 5pecifications for Road, Bridge;and Municipal Construction, as published by the Washington State Department of Transportation/American Public Works Associatioz�, an.d tha Specifications of the American Water Works Association. They specify requirements for utility location and minimum fire flows that are based on Grax�t , County land use development classifications listed in the Comprehensive Plan. 2. UTILITY STANDARDS The minimum design standards establzshed iz�the Coordinated Water System Plan are considered the minimum standards permittad�or new and expanding water systerns. New and expanding watier systems need to have a Water Systerrz Plan approved by DOH, which is znuch more detailed than.the design standards described herein. Althaugh a water utility has the authority to require more stringent standaz�ds, they ma� not reduce the standards for new services. These desigi� standards have been formulated as a minimu:m lavel of water system acceptability and have been based on good engineering practice and the requirements of WAC 246-290 and WAC 246-293. If any water utility chooses to expand upon the minimum standards, they are encouraged to coordinate the devalopment of their utility standaxds with adj acent systems to promote consistency throughout the CWSSA. IV-1 r The WUCC and DOH recommend the developer to follow both DOT/APWA's and AWWA's standard constz-uction specifications. 3. UTILITY PLANNING AND LAND USE CRITERIA The Public Water Systam Coordination Act provides that the individual water system plans are to be consistent with the area's land use plans. The utilities emphasized their desire to review and comrnent on land use changes occurring within their service areas that may impact their water systems. This creates the need to emphasize the uniform application of the Comprehensive Plan, allowed densities, and the �nforcement of minimum design standards within areas outside of claimed utility service areas. The CWSP acknowled�es the requirements and has incorporated thern into the Utility Service Review Procedure in Section V. 4. DEVELOPMENT OF URBAN SERVICES The Public Water Systems Coordination Act, Chapter 70.116 RCW, provides for existing water utilities to continue under existing design and construction standards, provided the system is not expanding, and meets State public health, watar quality, and pressure requirements. Consequently, the CWSP allows existing smaller water systerrzs to continue to provide service without modification of their existing systems within the urban area, without a system upgrade program. A system is considered to be expanding when either they exceed the number of approved service connections, or go outside their current service areas. In general, system infilling or adding new customers to the existing system, is not considered system expansion, and therefore if an ac�equate quality and quantity of water is provided to meet existing customer needs, the system is not required to upgrade their facilities. Under WAC 246-290 and 246-293, the utility provider sha11 prepare a water system plan and a program of capital improvements rec�uired to provide the anticipated level of service within their designated water service area consistent with the land use plan. When the utility is requested to provide water service, it will identify that portion of planned capital facilities, as well as other installations, which are necessary to provide the service requested. As growth occurs, the full level of water service will eventually be provided throughout the service area of the utility in a planned, phased program which meets County requirements and minimizes overall cost to the customers. In this case, the utility and developer may reach an agreement to provide the desired se�rvice through a schedule of improvements, which is specified by a legally binding contract. IV-2 5. GENERAL PROVISIONS A. Standards Committee A standards committee shall be comprised of representatives from local water utilities. Members of this committee shall be nominated by the Water Utility Coordinating Committee and approved by the County Commissioners. Technical advice from DOH and the Grant County Department of Community Developznent may be requested. The Committee shall convene as necessary to review the standards and their implementation. The Comrnittee shall make recommendations for changes, if necessary, to the Grant County Commissioners. B. Materials and Specifications , Except as specified by the individual water purveyor, for specific projects or in their standard specifications, all material utilized in the construction and installation . of water systems shall conform at a minimum to the most current editian of standards of the Standard Specifications for Road, Bridge, and Municipal Construction as published by the Washington State Department of Transportation/American Public Works Association (DOT/APWA), and the Specifications of the American Water Works Association (AWWA). Prior to construction, a County or City Permit, as appropriate, must be obtained. All rec�uirements of the permit shall become part of these specifications. C. Regulatory Compliance A.11 water systems shall comply, at a minimum, with the requirements of WAC 246- 290, "Rules and Regulations of the State Boaxd of Health Regarding Public Water Supplies," WAC 246-293, "Water System Coordination Act: Fire Flow Requirements," and all other applicable County, State, and Federal regulations. 6. SPECIFIC PROVISIONS A. Water Quality, Quantity and Pressure All water systems shall comply with the requirements o�WAC 246-290, Rules and , Regulations of the State Board of Health Regarding Public Water Systems, and all other applicable state and federal regulations. ' B. Watar Mains All new or replacement water mains shall meet the criteria of AWWA(C900-75) Class 150. The minimum acceptable plastic pipe is ASTM PVC 160 (80 psi). IV-3 An 8-inch minimum pipe diameter shall be used unless hydraulic justification can be provided for smaller mains. The hydraulic analysis shall considex the appropriate land use designation and fire flow requirements. Fire hydrants sha.11 not be installed on mains whose diameters are small�r than 6 inches. C. Bedding, Cover, Thrust Blocking, Valves and Fittings DOT/APWA standards and manufacturers' recommendations shall be followed for the selection and installation of proper bedding, standard fittings, thrust block strength requirements and placement. All valves shall comply with AWWA standards and be rated at 150 psi working pressure or greater. At least 42" of aover is required between the top of buried pipe and the finished grade. D. Utility Placement The placement of all water mains, fire hydrants, and other water facilities shall be located in a public right-of-way. Where public rights-of-way are not available, permanent utility easements shall be obtained which have a 20-foot miniznum width, unless other arran�ements are made between the developer and purveyor. Specific location, size, and alignrnent of water lines shall be such that emergency interties are possible with adjacent utilzties. E. Fire Flows In the table below, land classifications and fire flow are based on Washington State Department of Health WAC 246-293-640. These requirements apply to all Group A community (15 or more connections)water systems. When designing a water system, the water system must be able to meet the fire flow standard and the normal domestic maximum demand with the largest source out of operation. If the vvater system depends on an intertie to meet minimum standards, then the intertie valva znust operate automatically. Note: The Grant County Fire Marshall, or other local fire authorities, may impose more stringent fire flow or other requirements needed to provide additional protection required by struatures, cornplexes, and developments, or projects which are increased fire risk hazards. Fire flow for Non-community public water systezns shall be set on a case by case basis by the Fire Marshall. IV-4 Develo�ment Classi�cation Minimum Fire Flow Rural(1,2) None Residential 500 gpm for 30 minutes Multi-Family(3) 750 gpm for And Commercial 60 minutes (4) Industrial 1,000 g�pzn for 60 rnznutes (4) (1) Proposals for rural land uses are exernpt from the fire flow requirements (but are not exempted from any requirements placed u�on the proposal by the Fire Marshall). (2) Rural (in its application to fire flows) are lot sizes that are greater than one acre whose structures are at least 25 feet from the property boundaries. (3) Multi-family Structures greater than 4,000 sq. ft. (4) Commercial and industrial buildings may be subj ect to higher flow requirements when evaluated on an individual basis by the local fixe protection authority. F. Fire Storage and Pressure Minimum fire storage volumes shall be sized to be compatible with the Department of Health fire flow, standby storage, and equalizing storage requirernents, A minirnum residual pressure of 20 psi��under�eak domestic and fire flow conditions is required at all fire hydrants. G. Fire Hydrants The placement, spacing, and type of fire hydrants installed within water utilities must receive the approval of the appropriate local fire protection authority prior to installation. It is further specified that all hydrants be located in public rights-of- way or as designated by the local fire authority. All provisions of WAC 246-293-650 are endorsed by these standards. H, Watex Meter Installation All installed water meters shall confoz-m to AWWA standards. Water service lines fronn the main to the meter with 1"to 12"diamaters must nneet or exceed ASTM PVC 160 for pressures of 80 psi or less and ASTM PVC 200 for pressures greater than SO psi. All service lines beyond the meter must comply with the provisions of , the Uniform Plumbing Code. IV-5 7. SEVERABILITY If any provision of these standards or their application is found to be invalid, the remainder of the standards and their implementation is not aft'ected. In addition, these rrzinimum standards do not supersede any existing or future standards legally imposed which are more stringent than these standards.

BACKGROUND In Grant County, past water supply practices have ganerally been canducted with limited coordination between adjacent utilities and without adequate planning for the urbanizing areas. The Coordinated Wa�er System Plan(CWSP) has sought to establish an administrative program which effectively guides the development and expansion of ' water utilities for existing and future customers. City-County land use�olicies shall �stablish growth trends within the Critical Water Supply Service Area. Therefore, the Coordinated Watar System Plan was tasked with synthesizing seve�ral independent standards and objectives into a program that can be uniformly applied to requests for water service from new or existing water utilities. The procedures presented within this section include the refinements and improvements identified by individual utilities, and City and County staff during the plannin�process. , 2. CWSP UTILITY SERVICE REVIEW PROCEDURE APPLICABILITY The Utility Service Review Procedure (USRP) developed for the CWSP is applied to all water use activities that require the Grant County Department of Commun.ity Development (GCDCD) approval of new plat development or proposals for new public water systerns through GCHD or DOH. For plat approval and building permits, the GCDCD will initiate the reviaw procedure and ensure that the appropriate coordination is conducted between the applicant and all respective review agencies before the issuance of any permits or preliminary plat approvals. For new water systems, either the Grant County Health District or Department of Health will manage the process. The review pro�ram in the CWSP provides a mechanism to ensure that utility service areas are honored by the County, the developer, and the utilit� alike, In additzon, t�e procedures focus on measures to effectively identify required fire flows �arXy in tYze developznent stage, to ensure that land use policies are uniformly applied, and to notify utilities of land uses, proposal of new public water systems, and. the issuance of building pezmits that require water service as they occur. , Some utilitias utilize various forms of annexation policies as a prerequisite for water service, therefore the review procedure has been developed in a fashioz�to eiasure that those utilities h.ave the first opportunity to �resent their conditions of service (financial, technical, and aru�.exation requirements) to applicants within their service area. Expansion of at� existing system within its designated service area(consistent with its DOH current and appro�jed water system plan) may proceed without need for further review. (As long as it doesn't go over its approved number of sez-vices) V-1 3. PRE-SUBMITTAL REVIEW PROCESS (not part of USRP) Water service review will occur as a component of development permit processing. Prior to submitting a formal permit application, development proponents are to utilize the pre-submittal review process. Development review information will be submitted for pre-submittal review to the ap�ropriate water system. On the basis of preliminary information provided by the applicant, the designated water syster�will provzde preliminary indications of water availability and conditions of sezvice. These preliminary contacts do not constitute a fonnal application for water service and do z�ot initiate the timeline for water system response. 4. UTILTTY SERVICE REVTEW PROCEDURE As shown in Exhibit V-T, the Utility Service Review Procedure follows the procedure described below. A. Phase l: Service from a Designated Water 5ystem For new developrnents within a purveyor's designated. service area, as shown on the official maps held at the GCHD, service will be fxom the existing designated water system. (1} Development within a city's jurisdictional area will need to apply to the appropriate city. This may require joint planning with the city and the GCDCD. For plat approval and building pern�its the GCDCD wi11 receive the application and the County Fire Marshall will designate the required fire flow before the applicant is sent to coordinate there supply needs with th.�utility. Expanding or new public water systems, not needing plat approval or building permits, will be rnanaged by the GCHD or DOH. (2) The city or the GCDCD will direct the entity requiring water service to th.e Grant County Health District who will assign the project to the designated utility service area. (3) All proposed projects will then be reviewed with the designated water utility to identify the conditions of service. Th�water utility will have operational and managerial responsibility for the proposed activity and may require more stringent design standards than those of the County (as deterinined in an approved Water Systezn Plan). The water utility will specify a�l design requirements and their estimated cost of providing seivice to th�proposPd development. (4) The water utility and applicant shall provide a signed agreement of water ` availability regarding the provision of service to the a�plicant before the issuance of a building permit or pxeliminary plat ap�roval. The agreement of V-2 water availability shall include a timeline for both the provision of water and for the completion of the development. This agreement between the utility and applicanC will verify their intent to implement one of the following options: (a) The utility will serve the applicant through a direct extension of the water systezxfl. (b) In some situations, a new developnnent within: a utilities designated service area may be outside the area which can practically be providad for direct service in the capital improvement program. For small scale development in the outlying portions of the service area, tha cost of water line extensiol�may make direct service from the central water system impractical. In these situations, a"satellite"water system, physically separate but managed as part of a larger water utility, may a11ow timely and cost-effective water service to naw developments while ensuring futuxe incorporation into th� central water system. Utilities pursuing remote (through ownership or management and operation) service will need to become an approved Satellite Management Agency. Utilities not already approved may seek assistance from DOH. (c) The utility is unable or unwilling to provide water service, thereby initiating a change in the designated utility service area boundary. (5) The process will move to the next F'hase only if the following conditions are rnet. 1. If the water system deterriiinas that neither direct hookup to the water system nar satellite service (znanaged and operated by the water system) are reasonable alternatives. 2. The development requiring water is not located within a designated service area. 3. 'I'he entity seelcing water service files a successful appeal. (See Section 5, Appeals Process) (6) Once the water availability agreement (consistent with DOH WSP) and preliminary plat (if needed) are approved, the water facilities are i�stalled to meet the iztilities minimunn standards or are bonded for completion. Once the system is installed, the Certificate of Completion is sent to DOH. (7) Once the Certificate of Completion is received, the final p�at is signed by tlle Grant County Health Distriat. �I-3 - B. Phase 2: Service from an Adjacent Utility (1) In the event a new development is proposed within a 1/4 mile of a Group A water utility's designated service area boundary, the DOH requires the development to seek water service from the Group A utility as stated in WAC 246-293-190. If the entity seeking water is located within 1/4 mile of two or more utilities, then they can select which utility they�refer. Under no circumstances would a Group A utility be required to expand its boundary if it did not desire to do so. However, the common approval of such action by both the County and the Group A utility would enable the water system to expand its boundaries after the official water service maps and the WSP are amended. (2) The procedure for determining if service is available and for negotiating agreements for conditions of service from an adj acent utility is the same as for developments located within a designated service area. (See steps 2 - 6 from part A, Phase 1, above) C. Phase 3: Service from a Satellite Management Agency In conformance with RCW 70.116.134, the Grant County Healtk�District sh.all direct the individu�l(s) proposing the new public water systam to one or more satellite managernent agencies designated for the service area wh.ere the new system is being proposed for the purpose of exploring the possibi�ity of a satellite a�ency either owning or operating the proposed new water system. If the applicant is: 1) not withi� an existing purveyors designated service area and unable to receive water from an adja.�ent purveyor, and 2) one or more Satellzte Management Agencies serves the applicants area, then the applicant must seek service from an approved SMA. (1) In the event the proposed new system is within an approved SMA's sezvice axea, then the applicant must seek service from that S1VIA(s). The SMA should meet with all adjacent utilities ko discuss possible interties that znay occur ir�the �uture. (2) The procedure for determining if service is available and for negotiatzng agreem.ents ot'service from an approved SMA utility is the same as for developments located within a designated service area. (See steps 2 - 6 from part A, Phase 1, abov�) D. Phase 4: New Water System Proposed Service from a new water system may be proposed only if it has been determined that water service is not availabla from Phases 1, 2, or 3 from above or that through '�l-4 the appeals process it is determined that conditions of service from all other available water systems are not timely and/or reasonable. The process for proposing a new water system is: (1) The new system is proposed. The proposed new water system rnust complete and receive approval of a Water System Plan (Group A) or a Group B manual. Group B systems with 3 — 9 connections will be reviewed by the Grant County Health District. Systems consisting of 10 or more connections will be reviewed by the State Department of Health. Most Group A systems will need water rights as well as some Group B's (depending on the size of the systern). � (2) The praliminary plat must then be approved. (If applicable) (3) The new system is installed and the Certificate of Completion sent to the DOH. (4) Once the Certificate of Completion is received, the final plat is signed by the Grant County Health District. 5. APPEALS PROCESS Traditionally disputes that arise over timely and reasonable were managed by the Department of�-Iealth. RCW 70.116 altered this process by shifting the dispute resolution process to the local legislative authority. The following dispute rasolution process applies specifically to timely and reasonable disputes in unincorporatad areas of the county. When these issues arise with�n incorporated areas, their resolution will be thxough the procedures established by the responsible city or town. A. Issues Subject to Appeal and Review Only water service issues relating to retail water services are subject to appeal and review under this process. Issues related to conformance with the State Environmental Policy Act, the State Growth Management Act, any County-wide Regional Planning Policies, Satellite Management Agencies, County and City la�1d use plans, financing policies, an.d wholesale agreements are not subject to appeal and review under this process. Issues subject to review are limited to the following: (1) Interpretati�n and application of water utility s�rvice area botu�daries wl�ere ap�licable. (2) Proposed schedule for�roviding service. (3) Conditions of servica, excluding published rates and fees. V-5 (4) Minimum design standards as adopted in the CWSP, or more stringent standards as contained in a utility water system plan approved by DOH. B. Review Process It is expected that most issues will arise over the question of what con.stitutes timely (see Part F below) and/or reasonable conditions of water service. If an applicant and a utility are unable to agree on conditions of service, a written request for review of the issues may be made to the GCHD. The GCHD will initiate the review by determining if the appeal is valid. The GCHD will then try to facilitate a resolution. If requested, the DOH may provide informational support and technical assistance during the appeal process. The GCHD will consider the followxng objectives while trying to resolve the conflict. (1) Obj ectives The review process will be directed to achieving the following obj ectives: • Provide a forum for negotiation of the issues between the parties • Facilitat�the negotiations. s Pursue equitable representation of interests between parties. • Reach agreement between parties. • Identify and evaluate the facts associated with the issues. (2) GCHD Report When the appeal has been resolved, the conditions of the agreement will be reported. A full or conditional notice of withdrawal of the appeal by the applicant shall accompany the report. Where resolution was not achieved, the GCHD will refer the controlling issuas and the position of the parties to the County Commissioners, C. Forznal Appeal If t��e recommendation from the GCHD is not accepted by either of the parties to the dispute, the next step is to initiate a formal hearing of the dispute heard by the County Commissioners. The GCHD will report their findings to the Count� Commissioners. I�. Final Appeal Superior Court is the last option to resolve dis�utes concerning timely and reasonable water service. V-6 E. Appeal Results If through the appeals process it is found that the puzveyor's conditions of servica are timely and reasonable, then the developer must decide to accept the conditions, or not develop. If through the appeals process it is found that the purveyor's conditions of service are not timely and reasonable, then the purveyor znust either redefine th�ir conditions of service, or relinquish that part of their sezvice area, and the applicant moves to the next Phase in the USRP. (See Exhibit V-1) F. Timely Service An existing purveyor is unable to provide the service in a timely manner if the water cannot be provided to an applicant for water within one hundred twenty days unless specified otherwise by the local legislative authority. The law does not, however, define at what point in the process the one hundred twenty day time period is to begin. The one hundred twenty day time period will begin. once the utility has received a cornplete project a�plication from the entity requesting water service. 6. SPECIAL REVIEW CONSIDERATIONS A. Land Use Changes, Building Permit Approvals, and New Public Water Systems The County review procedures are designed to alert water utilities of�roposed land use activities in thair service area which affect the water utility and allow them to identify the impact on their specific utility prior to the approval of preliminary plats, building permits, and new public water systems. Industrial and Commercial properties represent a fire flow responsibility of the utility that may greatly exceed flows for residential housing. Because these flows are critical in sizing storage, pumping, and piping facilities that affect capital improvement programs, the utilities shall have the opportunity to evaluate higher demand commercial facilities, and possibly mitigate conditions, before the issuanc� of a building permit. B. Group B Systems The proliferation of smaller Grou� B water systems is not encouraged by th� CWSP. This philosophy reflects the fact that these systems, due to their size, �re normally limited in financial and managerial capaeities needed fox effectxve continuous operation. The CWSP acknowledges their importance as e�isting pu.rveyors; however, it does not require or desire that they identify a designatecl service area. Instead, the CWSP assigns Grou� B systems to the deszgnated service V-7 areas of Group A systems whenever possible. In particular, it is important to include systems within the CWSP process as they attain a Group A status. However, special consideration is required for the expansion of Group B systems both inside and outside designated service areas. (1) Expansion Outside Designated Service Areas Group B systems wishing to expand must show they can meet the Maximum Instantaneous Demand (MID) and will be reviewed by the appropriate jurisdictional agency. Group B systems with three to nine connections will be reviewed by the Grant County Health District. Systems consistin� of 10 or more connections will be reviewed by the State Department of�-Iealth. Systems expanding from four ar less connections, to between five and nine connections without the adequate water rights, have the following requirements. 1. Must have a water users agreement that the total water systems will not use over 5,000 gallons a day (total usa�e). 2. Must have source flow meters installed. 3, Must have domestic water separate from irrigation water. 4. May only have one outside hose connection per residence, with a flow restriction device installed. Group B systems, proposing to expand, with m.ore than nine connections are required to have a Professional Engineer (PE) and adequate water rights. Group B systems that expand to Group A systems must establish their designated service area, submit a completed Service Area Agreement, and complete a Water System.P1an. (2) Expansion Within Designated Service Areas. The CWSP places a responsibility on the review agencies to honor a specifzc utility's service area and, in turn, urges the utility to assume responsibility for effsctive management of water service wxthin that area. C. Failing Water Systems State legislation [RCW 70.116.050(4)(g)] stipulates that a Coordinated Watex System Plan"include policies and procedures that generally address failing water systems for which the counties may become responsible under RCW 43.70.195." The County is identified as the receiver of a failed water system in the event that no other�person is willing and able to take on the system. In such situations, the County is designated tha receiver for purposes of designating the system operator ' and providing regulatory oversi�ht in conjunction with DOH (see RCW 43.70.195). V-8 However, the receivership process is very difficult for all partici�ants and is not the preferred route for resolving small water system problems. In the event of receivership, it will generally be preferable for small water systems to be integrated into the designated water system, provided financing and other conditions of the designated expanding system are nnet. Each designated expanding system or approved satellite operator shall adopt a policy regarding water system receivership in their water system plan. These policies shall designate conditions under which, if willing, it would become an authonzed receiver within its designated service area, with the understanding that the water system does not waive its rights to appear and�participate in the court proceedin�s to determine if acceptable conditions or receivership can be established. ,; V-9 U"I"�I�IT`a' SF�RVICL 1ZI;�f1���'PRt�C�DURLS t�t�iZ Nt�111 I7E��fI�LOP�.�I_�N�I' O£� NI��'�t PUI3LIC ��'f��i"�R SYSI�I��f� 1�E�asc I Pl�ase 2 Pilasc 3 i'hasc ti Gra��t �oz��1(y �c��ar(�7�cz�t t�f DevelaJ�er Reterred �y Deve(oper ReCerred I�}J — Netv Systern Coi��n�ul�it�� J�cE�el�}���er�t GCN_I7 to �d�ace��fi Utilify GC��D to Si��IIE � 1'ra�osed Ti��e I�lt�«� IZe�ciirci�le�7ts � �s�3�12eci by i���-c ��ars�17I1 �icfjacer�t ��tii� Cotlsider Ui��ect �o SI�1�, Wi1I Serve Nc� � ���t' or Grot�{� L3 crr T�.e��iote Servi�e �`es 1 ��€�nual i�c(crrccf (c� CfC:Ili7 Yc� � � D01-i or �iCIIC� i'rt���os�� i�� I7csf�natcc( Nc� � I'urvcyag- ��7i7r�c�ljal t'r�c�ccss � ����}rr�v�! �V�tfcr Lltilit}r �crvicc �rc<t I.

INTRODUCTION The Coordinated Water System Plan (CWSP) encourages utilities and governmental agencies to jointly address issues to improve the reliability and performance of adjacent �itilities and/or assist in resolving regional water su�ply problems. The major issue comrnonly affecting public water systems within the Critical Water Suppl� Service Area (CWSSA) is the availability of future water resources. There are locations within the CWSSA where the opportunity of shar•ed fa�ilities and programs can be mutually beneficial to adjacent utilities. The benafits relate to reliability as well as sharing costs and economies of scale. 2. SHARED FACILITIES Due to the widespread location of water utilities within the CWSSA, the utilization of shared facilities are infrequently used and generally limited to the population centers. Of those existin,g shared facilities, interties for emergency supply situations are most commonl�used. As an example, the City of Quincy and the Weiler-1Vlartin Wa,ter Association have two valved connections that have been used in the past to supply either utility in emergencies. The potential of additional intertie arrangeinents does exist elsewhere within the CWSSA. The City of Quincy has a poteritial future intertie with the Golden Valley Water Association northwest af the City. The close proxirnity of the City of Soap Lake and the Lakeview Park Water Association may provide a mutual�y beneficial intertie in future years, In addition, the City of Mosas Lake may be able to provide assistance to sznall water systems surrounding and encompassed by�he City, The conditions of use wauld, of course, have to be established by a mutually satisfactory contract and be in confozmanGe with city and County Compxehensive Plans. Technically, problems with shared facilities generally relate to the hydraizlic compatibility of the participating water utilities. These technical issues amphasize the need for coordinated water system planning ar�d.design between adjacent utzlities. Provision.s such as standardized nverflow reservoir elevations for simila�r geographical areas will help minimize technical inconnpatibilities for shared facilities. Basically, there are three common types of interties: Emer ency � Standby source in case of power outage or other crisis situatioi�.s, increasing the reliability of the benefiting system. VI-1 Su�plemental Source - Intermittent use in instances where demand outstrips avazlable supply for a utility which has limited source capacity. Continuous Source � Permanent source of supply for a water utility, in lieu of developing wells, springs, or surface water or in combination with other sources within th�system. Of the three types of interties, emergency interties are the most common and axe strongly supported by the Department of Health. Interties may represent the most cost- effective means to achieve this reliability, provided that certain criteria are met. Those criteria should ensure that interties are adequately sized. An intertie will benefit the utility in need of water only if it is large enough to supply basic daily needs of the "receiving" systems. In addition, water utilities should consider the potential for sup�ly in both ways through the connection so that they can reciprocate in amergency situations. The other two types of in.terties are also supported by the Department of Health through its programs promoting regional cooperation. When the most feasible, technical, and institutional solutions involve sharing source, through either periodic or perrnanent interties, they are encouraged by the Department. However, it is extremely important that institutional arrangements concerning responsibility of operations and maintenance of an intertze are carefully and clearly delineated. Existing State law requires that the Department of Ecology (DOE) issue water rights for wells that supply a water system with�nore than 5,000 gallons per day. It has baen DOE's policy to identify a point of use which corresponds to the service area fox the individual water utility. The promotion of interties, regional supplies, and other shared facilities may conflict with State law if water right certificates do not reflect the potential of water supply transfers beyond the utilities service area. DOE has indicated that their position will not require water right modi�aation nor their long-terrr� �ormal authorization for erziergency interties. Both the Department of Health and the Departr�ent of Ecology have acknowledged their support for shared facilities which conform with local land use policies, improve reliable water utility service and promote responsible water resource management. The existing and potential shared facilities evaluated by the CWSP conform to these water resource objectives of the regulatory agencies. The complete planning and design re�uirements foz interties are currently being revised and can be obtained from. the State Departm.ent of Health. 3. COLUMBIA BASIN UROUIVD WATER MANAGEMENT AREA Adams, Franklin and Grant coun.tiPs petitioned the Washingtan State Department of �cology in 1997 to form the Columbia Basin Grou�id Water Manageznent�ea (GWMA). Ecology signed the ord�r creating the Columbia Basin GWMA on February 4, 1998, VT-2 Funded by local, state and federal sources, the GWMA,program will consist of water monitoring and characterization,public information and education, and implementation and researcl�. A series of ground water advisory committees have been formed to oversee the work program and make�rogram recomm.endations to an executive committee. The executive committee will review the recoziv�nendations of the various committee and present a final set of recommendations to the local conservatio�. dist�rzcts and the Boards of County Commissioriers of each county, who report to Ecology. Six agencies have also agreed to partic�pate in the program and in the development and iznplementatiox� of locally driven solutions to address ground water quality issues in areas of documented nitrate concern. Local agricultural industry representatives are also supportive of the GWMA program. A final report is expected in 2000. �4. WATER SUPPLY REQUIREMENTS A. Historical Water Use Historical water use factors were obtained from water system records maintained by the City of Ephrata, City of Moses Lake, City of Quincy, City of Geor�e, City of Soap Lake, and the City of Warden. Average water usage is based on the coznbined industrial and domestic consumption. The type of industrial development supporting existin$populations signifiaantly impacts total water usage. The data, which related avera�e and�peak water consumption for each system in recent years, was converted to a gallons per minute value for av�rage water consumption. T11e overall per-capita consumption is in the vicinity of 400 gallons per capita day average for these munzcipal systems. B, Population Projections In developing populatian projections, separate projections were developed for the City of Ephrata, City of Moses Lake, City of Quincy, City of George, City of Soap Lake, and the City of Warden. It has been estimated that for 1998, Ephrata provided service to a population of 6,065 within the corporate lzmits, azid approximately 33 outside, for a total population of 6,098. Moses I,ake provided wa.ter service to a population of 12,610 within the corporate lim.its, and 5,690 (primarily the Larson subdivision) outside, for a total o:F 18,300. Although the City of Quincy's incorporated population is 4,090, they provided water service to a population of 3,250. The majority of the remaining population within Quincy is served by the Weiler-Martin.Water Association. The remaining incorporated city populations within the CWSSA, are: Gearge 465, Soap Lake 1,370, and Warden 2,280. The City of Moses Lake is expected to have an overall growth of 3.0% over tl�e x�ext 20 years. The Cities of George, Quincy and Ephrata are expected to grow at a rate of 2.0% over the next 20 years. The City of Soap Lake is expected to grow at �I-3 1.5% and Warden at 2.5% over the next 20 years. Using the above population forecasts, in 20 years the City of Moses Lake is projected to have a population of 24,762 withzn the corporate limits. Adding the population of 5,690 outside the corporate limits (which is not expected to grow) results in a total populatzon of 30,452 receiving water service from Moses Lake. Quincy is projected to pxovide water service to a population of 5,238 (projected population less W�iler-Martin). The rernaining projected populations are: Ephrata 9,012, George 691, Soap Lake 2,036, and Warden 3,736. 'I'he resulting population projections over the 20-year planning period for each of the cities discussed above are presented zn Table VI-1. C. Water Demand Projections Projections for future water consumption for cities within tha CWSSA are , presented in Table VI-1. These projections are based upon historical water use records and population projections discussed earlier in this seation. Approximately 85 percent of the public water supply requirements are provided by all the municipalities with the remaining 15 percent supplied by other public water systems within the CWSSA. Individual systems on private wells will add an additional future demand. Irrigation is another major contributor to water demand. Irrigation users are allowed 0.02 cfs per acre, which is approximatiely 9 gpm per acre. Irrigating 160 acres would then require an average daily demand of 1,440 gpzn. This is roughly equivalent to the combined average daily dernand water usage of the City of George, City of Soap Lake, and the City of Warden. D. Conservation As puUlic recognitior�of the competing demands for available water supplies increases, m.ore attention is focusing on water conservation. With the variety of conservation tools now available, conservation can offer a variety of different benefits to utilities and their customers. The conservation programming needs to be carefully matched to the objectives of the utility, so the desired banefits can be achieved. Some of the objectives that might be achieved from the wise use of water through water conservation are: • Manage the Scale and Timing of New Supply and Treatment It has become increasingly difficult to develop new sources of water supply throughout the west. This trend is lzkely to continue as growth spurs increase the need for water while at the same time environmental and water quaXity requirements grow more stringent. Utilities across the nation have found that VI-4 conservation programming can reduce, or delay, the need for new sources of supply, while increasing public support for new sources of supply when they are needed. At the same time, increased regulatory rec�uirements for water treatment have driven up the cost of sup�lying potable water. By reducing water needed, conservation can also lower the cost of water treatment. s Reduce Utility Operating Expenses Reducing water consumption and system losses allows a corresponding reduction. in chemical usage and energy consumption, which can lead to savings in�.itility operating expenses. In addition, a comprehensive leak detection and repair program aan reduce expenditures on emergency repairs. • Reduce or Delay Investrnents in Wastewater Capacity Given the direct connection between water consumption and wastewater flows, conservation offers a means to reduce demand on wastewater collection and treatment systems. This in turn can reduce or delay capital expenditures on wastewater collectzon and treatrnent capacity. • Minirnize Impacts on Natural Resources By reducing the amount of water diverted from streams or pumped from aquifers that recharge rivers and wetlands, conservation provides a tool for utilities and their customers to minimize their impacts on the natural environment. • Conservation as an Ethic '% Citizens and public officials acicnowledging water as a scarce resource can nnanage its use efficiently to ensure continued availability. Conservation ma�then be implemented even though it is not the most cost-effective alternative to other supp�y development optzons. + Giving Customers Tools for Managing Expenditures The rising costs of water supply and treatm.ent, as well as wastewater treatment, are usually passed on directly to customers in the form of monthly rates. In addition, energy expended on heatzng water can add up to a significant fraction of the total cost o�water use. Conservation techniques can provide tools for managiz�g expenditures. Providing informatiori and conservation devices that allow custarners to control their water usa can offer significant methods ta reduc� persona.l utility rates. • Regulatory Compliance VI-5 llOH now requires utilities to evaluate a ranga of conservation options in preparing water system plans. The Department of Ecolo$y requires implementation of conservation zneasures found to be cost-e��ective, as a condition an gxanting new water rights to public water suppliers. Conservation Packages The term "conservation" embraces a range of programs for both supply and demand management. Supply elements are often forgotten in discussions of conservation efforts, yet ca�be implemented readily and may be among the most cost effective tools available for managing water use. Supply inanagament options include, but are not limited to: o Leak detecrion and repair � Main replacement • Corrosion prevention • Management of hydrant flushing • Meter repair, replacement, and calibration Demand management progranis involve customers in a variety of ways. These techniques range from supplying information and advice, offering financial incentives for installin�water-saving equi�ment, developing rate structures that build in an economic incentive to reduce consumption, or imposing regulatory requirenzents on plumbing fixtures, landscaping, ar water use. De:rxiaaid management progxarns can be, designed to reduce base water use,peak use, or both. Some common demand man��gement.elements include: • Broadly packaged infornaation aizd autreach(e.g. Advertising, billing inserts) N Narrowl�targeted inforrnation and outreach (e.g. Free water-usa audits for businesses and horz7eowtlers) s Improved metering • Hardware retrofit programs � Hardware rebate programs • Conservation rates * Landscaping ordinances • Seasonal outdoor use restrictions • Recycling or re-use prc�grains Costs of Conservation The exact package of supply and demand management measures that is most cost- effective in achiaving overall objectives varies from one utility to anothar. There is a�vide variety of residential conservation equipment, associated water savings, useful pr.oduct life, and c�st of different devices. Conservation pro�ratns may involve both up-front expenditures and continuing investments over time. While �II-6 developing a conservation program, it is important to consider not only the aosts and savings to the utility, but to th.e custo�ner as well. While performing an analysis of expected costs and benefits is important to conservation planning, it should be recognized that in many cases, water savings cannot bP projected with precision. Therefore, decisions on conservation programming require careful consideration of the importance of other factors besides cost-effectiveness. For example, as a matter of policy the utility may decide to promote conservation in order to respond to community desires, or offer increased protection to an environmental resource. In additian, it is important to consider the impact on a variety of customer alasses and income groups zn� designing a complete conservation package. Finally, utilities contemplating conservation programming need to fully analyze the revenue implications of reduc�d water usage. These revenue implications need to be addressed in terms of wastewater system needs as well. Guidelines, Requirements, and Recomrnendations The State of Washington, through DOH and Ecology, has developed policies on water conservation planning. A water conservation plan is required in order to gain approval of water system plans and new water rights. DOH has a publication entitled Conservation Plannin�Requirements that lays out expectations for water use data co�lection/reporting, demand forecasting, and conservation programmzng which are reviewed by both DOH and Ecology. The State guidelines recognize explicitly the importance of selecting conservation measures on the basis of cost-effectiveness, The guidelines are broken down with differing levels of planning required-clepending on the size of the utility. The CWSP recommends that WLJCC members initiate conservation efforts that aan be jointly implemented by several utilities and achieve cost savings through combined purchasing. Specific recommendations are for joint contracting of leakage detection analysis and the procurement of public education material. The DOH and American Water Works Association are sources of literature and material, which could be tailored for area utilities. This material can also be customized to acknowledge the WLJCC organization or speci£'ic utilities on brochures and other�iterature. E. Water Rights In Washington, tha allocation of water is governed using a system of permits known as water rights, which is administered by the Department of Bcology (Ecology). Among its other functions, Ecology is the state agency responsible both for preserving and protecting water quality and for administering the water rights permit system. It is Ecology's responsibility to help develop and implement integrated water quality and water quantity policies. VI-7 Each year, Ecology receives more than 1,000 applications to use surface and ground water in Washington. Although there are approximately 165,000 claims for surface and ground water currently on file, there are between 4,000 and 5,000 applications awaiting action by Ecology. Of these applications, about 1,000 cannot be acted upon due to unresolved lega� issues. Although a sizable backlog exits, a ' bill to set fees for processing water right applications did not pass during the 1994 legislative session. As a result, current fees remain the sarrze as they were in 1917. The state budget for water right decisions was cut by about two-thirds a.n.d t�.e nurr�ber of Ecolo�y staff making water rights decisions reduced from 54 in 1993 to 19�eople on.July 1, 1994. , Although several innovative approaches based on consensus decision-making have been implemented to resolve regional water management issues in Washington, the Le islature has not a ro riated the fundin re uired to uanti instream flow g pp p g q q fY requirements, inventory consumptive use requireznents of various land cover/land uses, and estimate the temporal and s�atia�distribution of water uses within the st�te. The uncertainties created by th.e unquantified water rights constrain planning and inhibit investments in water management facilities. The impacts of this uncertainty in water allocation are becoming more of a problem as the po�ulation increases and more demands are placed on the finite resource. Exempt Wells With four exceptions, all ground water withdrawals must hava a water right permit. The four exceptions are: stock-vvatering purposes, watering a lawn or a, noncommercial garden not exceeding one-half acre in size, single or group dor�iestic supply not exceeding 5,000 gallons a day, and industrial water supply not exceeding 5,000 gallons a day. Wells that supply this ground water are called "exempt wells" since they do not require a water right permit. It is noted that the 5,000 gallon a day limitation applies to only two of the four exceptions. Exempt wells are generally used to withdraw negligible quantities of water relative to Class A systems. Although Class B systems are "short straws", the increasing number o�exempt wells increases the potential for ground water contamination. Pumping of these wells can draw pollutants into previously uncontaminated ground ' water aquifers which tl�emselves contribute to surface water flows, Neither aurnulative water quality or quantity effects or public health issues are considered in the installation of exeznpt we11s. Water Rights Transfers Water right transfers are one way to change axisting rights to rights that satisfy society's changing needs—as long as other existing rights and the public interest VI-8 • , ; i are not impaired. A water user may petition Ecology for a change in the purpose, � amount, place or use, or point of diversion of water as stated on the certificate of water right. Water right transfers do not develop supplemental water supplies— they move existing supplies from low value to high value uses. However, such transfers and the subsequent reallocation of water resources may reduce or eliminate the need to develop additional sources. F. Growth Management Act The 1991 Growth Management Act (GMA) requires cities and counties in the state to do a defined level of pla:nning. The basic objective of the legislation is to guid� and encourage local governrnents to evaluate their goals and community assets, develop written comprehensive plans, and implement the plans through regulations and innovative techniques. The primary role of the state is to assist and enable local governments to design their own programs to fit local needs and opportunities, Compxehensive plans developed under the GMA are to be Gonsistent with the following state goals: conservation of important timber, agricultural, arid minera� resource lands; protection of critical areas; planning coordination among neighborhood jurisdictions; agreementi of capital and transportation plans with land use plans; and early and continuous public participation in the land use planning process. Public facilities and services such as water su�ply are included in these goals because o�their importance in supporting existing and future development. The GMA requires that each applicant for a building permit provide evidence of an adequate water supply for the intended use of the building. In addition, public facilities and services necessary to support development shall be adequate to serve the development without decreasing service levels below current, locally established minimum standards. This is referred to as the concurrency requirement. The GMA also requires that the land use elements of comprehensive plans provide for the protection of the quality and quantity of ground water used for public water supplies. The land use element must include drainage, flooding, and storm water guidelines for corrective action to mitigate or cleanse discharges that pollute waters of the state. 5. LEAK DETECTION Water systems experience water loss between the source and service connections. These losses are primarily due to faulty valves and old piping. Unmetered uses such as fire hydrants and construction uses are considered unaccounted water use, not leaks. The simplest method of detecting lealcs is to meter source production in conjunction with metered connections. This method is not only effective in.the detection of leaks, but also in determining the location of leaks. VI-9 Many purveyors have either developed leak detection programs or contracted with companies for the purpose of leak detection. Water purveyors located in other counties have been able to work together to develop leak detection programs. By doing so, they are able to reduce individual costs. With the abundance of water systems located in close proxirnity to each other within the CWSSA, it would benefit water puzveyors to develop joint leak detection programs. 6. WELLHEAD PROTECTION PROGRAM All Group A public water systems in the state using wells or springs (excluding systems using purchased sources, or interties) are required to develop a wellhead protection prograrn. The goal of the program is to prevent contamination of ground water used for drinking water. In Washington State, local wellhead protection programs shall, at a minimum, include the following elements: • A completed susceptibility assessment; • A delineated wellhead protection area for each well, wellfield, or spring; • An inventory within the wellhead protection area of all potential sour�es of contamination that may pose a threat to the water bearing zone (aquifer) utilized by the well, spring or well �eld; � Documentation that delineation and inventory findings are dist�.buted to required entities; • Contingency plans for providing alternate sources of drinking water in the event that contamination does occur; and ' • Coordination with local emergency responders for appropriate spill/incident response measures. A wellhead protection area is the area managed by a community (or private water association, homeowrner's association, etc.) to protect its ground water based drinking water supplies. Wellhead protection areas may cansist of four or fiv� zones: the standard sanitary control area, three additional zones based on tha one, five, and ten- year time of travel rates, and, where appropriate, a larger buffer zone. Without implementing management strategies to prevent potential contaminant sources � from becoming actual sources of ground water contamination, wellhead protection planning accomplishes lzttle. Since many purveyors do zlot own o�control all of the land that falls within their wellhead protection areas, an effective wellhead protection program must have the cooperation of those who do have control (i.e., local government, agencies, land owners). A key step in managing the wellhead prot�ction area is accomplished through the invantory requirements of notification or VI-10 owners/operators and regulatory agencies ragarding the location of potential contam.inant sources. Public education is a very important part of managing wellhead protection areas. Once people understand t�at their activities might affect the water they drink, they are more willing to change their practices. Identification ot' the capture zones assists watex utilities in educating the community regarding the need for pollution prevention and the proper management of land use activities withii�the protection areas. Adams, Gz�ant, and Lincoln counties are working together to implement water utility's wellh�ad protection boundaries into GIS maps. As wellhead protection area boundaries are developed or refined the GIS maps will be updated. The State Department of Health has developed policies on wellhead protection implementation. DOH has a publication entitled Wellhead Protection Prograrn Guidance Document, that definas the requirements for Group A water systems ko complete their wellhead protection program. 7. RECOMMENDATIONS Based on the information presented within this section, the folXowing specific recommendations are�rovided to address the regional water resource issues and current growth objectives of Grant County and the CWSSA: A. All systems should constantly review and inodify their Capital Improvement Plans to maximize the benefits of shared facilities and interties. As these projects are identified, they should be submitted for DOH approval as a supplement to individual water system plans and the CWSP. ,; B. A unified leak detection program should be developed to help minimize costs to individual water purveyors. C. Conservation practices should be implemented. Education of water use and ef#'ective conservation rnethods is a good way to promote the reduction of water usage. D. The Wellhead pratection program once completed, should ba used to educate communities in their future development and water usage.

VI-12 , f- J � � ��d�'o� i I� IMPLEMENTATION 1. INTRODUCTION The Grant County Coordinated Water System Plan (CWSP) was prepared to implement the separatie various provisions of the Public Water System Coordination Act, Chapter 70.116 RCW and WAC 246-293. This Section briefly outlines the joint approval process for the CWSP, the regional administrative actions for innplementation, describes how the CWSP is routinely updated, and provides the environmental review. 2. CWSP APPROVAL PROCESS As outlined in Section II, the completed CWSP is presented in two parts: the provisions detailed in this document, and a compilation of individual water system plans to be reviewed by Grant County Health District and approved by the Department oFHealth (DOH). It is the responsibility of each individual water system to fulfill its water system planning requirements. The level of effort required to fulfill this is based upon the system size, the expansion plans of the utility, and the type of system ownership, Guidelines for preparing wa�er system plans are available from DOH. Water systems required to complete a water system plan will be contacted by DOH. Systems will then submit water system plans based on a schedule a�reed upon with DOH. Preparation of these supplemental provisions has been the respansibility of the County and the local utilities, acting through a Water Utility Coordinating Committee (WUCC). The WUCC provided the forurn to identi�y local needs and give direction to the development of this CWSP as it related to area-wide issues. Througl�the efforts of the WIJCC, its chairmen, the technical committee, and DOH and Cou�lty staff, the procedures, policies, an.d standards have been completed for all public water utilities within the Critical Water Supply Service Area(CWSSA). Th.e completed CWSP is submitted by the WL7CC to the Grant County Departm.ent of Cornmunity Developn:ient for appro�riate internal review and forwarding to the Board of County Commissioners. Count�review is to ensure there ar� no inconszst�nci�s wzth current land use plans, shorelina master programs, and/or developmental policies. The Board has sixty days u�on receipt of the CWSP to act on the document. The alteznative actioris the Board may take are set forth in WAC 246-293 (See Exhibit VII-1). After Board action, the CWSP is submitted to DOH, which must also act ttpon adoption within sixty days from the date the plan is submitted. Major changes to the CWSP elements, proposed prior to the five-year update of the CWSP, need to follow the same process for an�xendment as that outlined above for CWSP approval. Administrative and boundar�changes agreed to by utilities ox WLTCC VII-1 i � that are consistent with goals and the recommen.dations of the CWSP can be a�proved by the County and tl�e WUCC acting as the implementation committee. 3. ADMINISTRATIVE ACTIONS Implementation of this Plan will require administrative action at both the State and County level. Recent legislation (1991) enacted by the State Legislature has been phased into CWSP plan implementation. Program areas where new or arnended resolutions, regulations and/or ordinances may be necessary are as follows: .A. State Authonity (1) Substitute Senate Bi115357, enacted in the 1991 Regular Session, relates to Satellite Management Agencies (SMA). s DOH shall approve SMAs meeting the established criteria and sha11 maintain and make available to counties a list of approved agencies. • Prior to constructing a new public water system, the developer shall �rst be directed by the county to one or more qualified SMAs for�k�e purpose of exploring the possibility of a SMA owning or operatin�the proposed new water system. The Utility Service Review Procedure (USRP) described in Section V is consistent with the legislation. (2) Legislation related to public water system interties was enacted in the 1991 Regular Session. This Bill, SeEond Substitute Senate Bi115358, whose provisions are now codified as RCW 90.03.83 and summarized as fallows: + Interties are recognized as valuable management tools for pub�ic water systems. • Interties are defined as interconnections between public systems permitting exchange or delivery of water between those systems for other than em.er�ency supply purposes, vvhere such exchange or delivery is wit�in established instantaneous and annual withdrawal rates specified in the system's existing water rights. � The place of use of water resultin,g from zz�terties which wer� existing arzd in use as of January 1, 1991, shall be recognized for wat�r right purposes, provided there are no outstanding complaints on file with the Department of Ecolagy and the amount of water used is consistent with the water right document. Written notice of such interties is to be provided to DOH. TYie notice may be incorporated into the update of the utility's water system plan. Ecology is then to modify the place of use of water in related water �III-2 i E right documents consistent with the service area described in the CWSP and/or water system plan. • System interties where use commenced after January 1, 1991, are to be incorporated into tha CWSP or utility's water system plan fox review and approval by DOH and Ecology as part of the plan review process. The plan is to state how the intertie will improve overall system relzability, enhance the manageability of the system,provide oppartunities for conjunctive use, or delay or avoid the need to develop new water sourGes. This legislation enables utilities to address water right znatters related to system interties through submittal of water system plans or CWSP's to DOH, (3) Substitute House Bi11 1709, 1991 Regular Session, established an operating permit requiz�em.en� for Group A public water systems, no person rna�operate a Group A system wzthout a valid permit. The implementation provisions are now codified as RCW 70.119A.110. B. County Authority (1) Adoption of an ordinance or resolution implementing the Water Utility Design Standards as described in Se�tion IV. (2) Adoption of an ordinance or resolution, or other recognition of those service area boundaries supported by signed ServicP Area Agreements. (3) Adoption of appropriate procedures to require a signed Service Area Agraement (consistent with a DOH approved WSP) as a prerec�uisite to granting approval to � utility for service area expansion. 4. ENVIRONMENTAL I�OCUMENT The State Environmental Policy Act of 197�, Chapter 43.21C, RCW, requires that all water system plans prepared must be accompanied by an appropriate environmental document. An Environmental Checklist has beeri prepared for the County's CWSP and its recommended activities. This checklist is included as Exhibit VIZ-2. The CWSP has been prepared to establish administrative, management, and policy procedures to guide the growth of water system,s in the Grant County CWSSA. It is intended to address re,gional concerns withi.n the CWSSA which are not ordinarily included in each utility's water system plan. Examples of those regional issues are potential shared facilities, regional sources c�f supply, pro�edures for reviewing and approving future water use activities, minimwm design standards, wel.lhead protection progz•arn, leak detection, consezvation, and design.ated water utility sezvice areas. �III-3 i The CWSP contents are referenced in the SEPA Checklist. The CWSP has been developed in accordance with the County's Comprehensive Plan to reflact local la,nd r�se policies and requirements. Therefore, implementation of this Plan and the employnnent of sound engineering an.d construction practices during the implementation of each utility's Water System Plan will minimize any adverse impacts. 5. COORDINATED WAT�R SYSTEM PLAN UPDATE , Tn accordance with the provisions of the Public Water System Coordination Act, the CWSP shall be updated by the Water Utility Coordinating Committee when the County, State Department of Health, or the Water Utility Coordinating Coinmittee determines it is necessary. �� VII-4 Exhibit VII-1 STATE REGUL�1'I'IOI�1 RELA.TING TO L(�CAL REVIEW OF PLAN WAC 2,46-293-290 C�ORDINATED WATER SYSTEM PLAN—LOCAL REVIEW. (1) Prior to submission of a coordinated water systezn plan to the State Department of I�ealth(Department) for approval, the plan shall be reviewed by the county legislative attthority(ies) in the county(ies) in which the critical water supply service area is located, County review of the coordinated water system plan shall include at least one public hearing. (2) If no comm�nts have been received frorn the county legislative authority(ies) within 60 days of receipt of the coordinated water system plan, the de�artment may consider the plan for approval. (3) If within 60 days of receipt of the coordinated water system plan, the county legislative authority(ies) find an� segment of the plan to be inconsistent with adopted land us�plans, shorelines master programs, the following shall occur: (a) The county le�islative authority(ies) shall subrnit written description of their determination and justifiaation supporting their determination prior to the end of the 60 day period to the department and all affected parties. (b) The county legislative authority(ies) shall make every effort to resolve any inconsistencies within 60 da�s of submittal of written justification. (c) The department may approv��those portion� of the coordinated water system plan found not to be inconsistent with adopted plans and policies at any time after the initial deternnination by the county legislative a,uthority(ies). (d) If after the 60-day period establi.shed for resolution of inconsistencies an inconsistency still exists, the affected parties shall each present their final recommended altezzlative solution to the department. The departrrzent shall then review all alternatiY�e solutior�s and discuss its recommendations with the county(ies) and the water utility coordinating committee, If after two years of the declaration of the critical water supply service area the inconsistencias persist, the department may deny proposals to establish or to expand any public water system facilities which affect that portion of th� critical water supply service area being contc;sted. �II-S E�xbit vlz-2 G�"VT COiTN�'Y Eiy VIIZONiYIENTAL CHECKI,IST RC`V J.97-11-960 Ezivironmental Checl:list.

SUPPLENZENTAL SHEET FOR NO�PROJECT ACTZONS �do not use �his sheet �or �roject actions) Because these questions are very general, it may be helpfu! to read them in conjunction tiyith the list of the eleznents of the environment. tiVhen ansrvering these questions, be arvare of the exte�t the proposal, or the types of activities likely to result from the proposal, tivould affect the itetn at a greater intensity or at a #'aster rate than if the proposal rvere not implemented. Respond briefly and in general terms. 1) Ho�v would the proposal be likely to increase discharge to �vater; emissions to aix; production, storage, or release of toxic or hazardous substances; or production of noise? The CWSP zesponds to growth and related water demand. The C�,�/SP does not create the projected increase in population and attendant environznental impacts, Tha CWSP uses Census Bureau population projection �gures. The CWSP has an objective to be efficient and prudent with public resources, e.g. the joint plan of opezation encourages efflciency and a shanng of the resource. Proposed measuras to avoid or reduce such incr�ases are: T11ere are none. 2) Ho�v would the proposal be likely to affect plants, azvmals, fish, or cnanne life are: The CWSP has no effect on these resources. Implementation of certain aspects of the CWSP may have some effect, but such actions would be subject to individual environmental review, Proposed measures to protect or conserve p(ants, animals, fish, or manne life are: There are none. � 3. How would tkie proposal be likely to deplete energy or natural resources'? The CWSP has no effect on these resources. Implementation oF certain aspects oE the CWSP may have some effect, but such actions would be subject to individual environmental review, VTI- 17 Proposed measures to protect such resources to avoid or reduce impacts are: There are none, 4, I�ow would the proposal be likely to use or affect environmentally sensitive areas or areas designated (or eligible or under study) for �overnmental protection; such as parks, wilderness, tivild and scenic rivers, threatened or endangered species habitat,historic or cultural sites,wetlands, flood plains, or prizne farnilands? All elements of the CtiVSP must be found to be consistent tivith local land use plans, policies, and development programs to be approved. Specific actions proposed for implementation under the CWSP would be subject to environznental revietiv. Proposed measures to protect such resources or to avoid or reduce impacts are: There are none. , 5. How would the proposal be likely to affect land and shoreline use, including whether it would allow or encourage land or shoreline uses incompatible with existing plans? All elements of the CWSP must be found to be consistent with local land use plans, policies, and development programs to be approved. Specific actions proposed for iznplementation under the C�VSP would be subject to environmental review. Proposed measures to avoid or reduca shoreline and line use impacts are: There ara none. 6, How would the proposal be likely to increase demands on transportarion or public services and urilities? The C�VSP will provide clarity concezning water service to specific areas, thereby supportuzg growth planned under existing zoning and land use plans. � Proposed measures to reduce or respond to such demand(s) are; There are none. 7. Identify, if possible, whether the proposa� may conflict tivith local, state, or federal laws or requuements for the pratection of the envizonment. The CWSP is in the Eormat called for by Chapter 70,116 RCtiV and has had both state and local agency revie�v throughout its development. There is no conf7ict expected.

The goal of the project was to eventually irrigate one million acres of land using water from the Columbia Rivez�. The key to t11e water-distribution system was to liberally apply irrigation water to lands within the Ql�incy Basin, which is generally de£'ined as lying south of the Beezley Hills, east of Evergreen Ridge, and north of the Frenchtnan Hills in Grant County, Washington. Due �o abundant application of irrigation wa.ter, it �vas conceived by early engineering studies that groundwater 1evels would rise in the Quincy Basin due to deep percolation of the abundant irrigation water, and that the deep percolating irrigation water would follow the gezieral, natural grot�ndwater gradient of tlle area, which is south and east from the Quincy Basin Toward Dnimheller Channals. Early engineerinb studies contemplated that at Dnimheller C�iannels a dam could be co�structed �or the pt�rpose of capturing percolating irrigation water that entered the groundwater system and For storing direct surFace-�vater deliveries from th.e Colurnbia River. Thus, from its e�rliest inception, the Columbia Basin Project, hereafter called Project, contemplated the conjunctive use � of surface and groundwaters as a means for delivering water to land r�vithin tlle Project that lies south and east of Drumheller Channels. beginning in the early 1930's, the Wasllington State Hydraulic Er�gineer adopted a policy that all water passing beneath the surface of. the land within the Columbia Basin Project was strbject to State jurisdiction, and the State law (chapter 90.03 RCW) should prevail in the allocation of these waters. From that time until 1967, the State of Washington and the federal government, actin� through the Departrrrent of the Interior, Bureau of Reclamation, took advisary positions over allocation jr�risdiction for groundtivater within the Quincy Basin tk�at �vas the result of deep percolation of project waters. During the pendency of the jurisdictional dispute between the State of Washzngton and the Uriited States, the Washington Stale Le�islature in 1945 adopted an amendment to Title 90 RCW which clearly extended State jurisdiction over groundwater (ck�apter 90.4A� RCW). The amendment tr� Title 90 clarified most of Washington State law relating to groundwater, but left one area ot"vague State jurisdiction relatiz�g to the withdrawal and use of artificially stored groundwater. At RCW 90.44,130, the code . relates the method by which claimants to artificially stored groundwater have a right to state tb.eir claim to o�vr�ership. Ilere, the code requires that, prior to accepting claims to o�vnership to artificially stored groundwater, th� Supervis�r of Water Resources � must declat'e tha area, sub-area, ar zor�e �vhere there is artificially stored groundwater to be a critical groundwater area or sub�area for the purpose of administratively co�trolling withdratival in order that overdraft o�'public groundwaters may be prevented as far as is feasible. In other words, without action by the Supervisor of Water Kesources in declaring a critical groundwater area or sub-area, no claimant to the ownership of artificially stored groundwater has a route in law for tiling his claim � of ownership with the State, and without such legal right to file a claim to ownership oF artificially stored groundwater the State need 1�ot recognize a�y claizn to ownership to artificially stored groundwater. From the effective date of chapter �0.44 RCW until approximately 1967, the Supervisor of Water Resources maintained that there was no overdraft of public grour�dwaters ir� the Quincy Basin due to the plentifi�l supply of recharge from deep percolation o£Project waters, which the Supervisor of Water Resourres claimed were abandoned. The United States Dapartza�.ent of the Interior, Bureau of Reclamation maintained, however, that deep percolation of Project�vater was arti�'icially recharging the groundwater of the Quincy Basin, which artificially recharged grotmdwater could be recaphired at Potholes Reservoir, and that the State, by refusing to declare a critical groundwater sub-area, was continuing to allocate groundwaters tllat are in the Quincy Basin dt�e to artificial reck�arge resultis�g fxom Project activities. In a memorandum dated January 5, 1967, the Washington State Department of Conservation reported to the Project that the volume of groundwater rights autlzorized by the State in�he general area of the Qui�cy Basin amounted to 59,341 acre-feet per year, The memorandum further pointed out th�t the State had received applicatio�ls for an additional 10,405 acre-feet per year of groundwater withdrawal from the Quincy Basin. The lnemoranduin concluded that grot�ndwater appropriated in the Quincy Basin. area was probably at or nearly equal to natural recharge to the area. Subsequently, the State of Washington undertook, in cooperation�vith the U.S. Geological Survey, a five-year study of groundwater in the area served by tihe Project, The purpose of the study was to determine the volurne of naturally occurring groundwater recharge in the Quincy Basin, az�id to determine the volume of groundwater in the Quincy Basin due to daep percolation of Project waters. During the pendency of the study, the State agreed with the U.S. Depaz-tm.ent of the Interior, Bt�reau ot'Reclamation that no additiona�l groundwater witk�drawals would be authorized by the State within a definad area known as Area 3A within the Quincy Basin where groundwater flow is toward Potholes Reservoir, and that all permits granted by the State to withdraw groundwater t'rom the surroundzng area, Area 3B, where grot�ndwater flow is also toward the Potholes Reservoir but where tXlera is not as much Pxoject water, would not be processed to certificate of water right as is authorized by RCW 90.44.080. the points agreed upon were en.tered as orders of the former Washington State Department of Water Resources (DWR Dockets 67-3 and � 67-4), wh.ich later in 1967 were combined into chapter 508-14 WAC. The general location�of Areas 3A and 3B is shown on Figure l. To provide a means for the use of groundwater �vithin Area 3A (#'i�uxe �), �rovision was made at WAC 508-14-020(4) for persons �r�ishing to construct a well for the puzpose of witl�drativing groundwater from Area 3A to fzle witll the 5tate a natice nf intention of construction of said well or other diversion �vorks, In adzninistrative practice, this notice of intention �vas a preliminary step for the water user to obtain a license from the Project foi•the use of groundwater in Area 3A. In addition to filing the notice of intention, each pezson desiring to use groundwater within Area 3A was required at WAC 508-14-010(3)(a) to file an application for public groLindtivater with R23E R24E R25E R26E R27E R28 •�,29E R30E R31E R32� P,33E RS� " , � � � - - -•-t A� � + , GRAN3" CQ � � � Soap Loka � �� Eph fa �F- � �Odess� 3 a � � � ESJr' r -� fNCC�I_N CQ.

Tht�s, a person using groundwater under a Project license during the pendency of tha five-year study could continue to use the water under a State perznit if the five-year study showed addztional public groundwater is available for appropriation in Area 3A. By the notice of iz7tention method, a maximum of approximately 172,000 acre-feet per year of groundwater �vas licensed for withdrawal from Area 3A when the five-year study contemplated by chapter 508-14 WAC was completed in late 1972, With completion of the five-year study, information became available to show that average long-term recharge to the Quincy Basin is about lOS,000 acre-feet per year, of which approximately 70,000 acre-feet per year of groundwater enters the Quincy Basin by lateral inflow to the upper aquifer (sand and gravel) from Crab Craelc (37,000 ' acre-feet per year), and 27,000 acre-feet per year by groundwater inflow around the perirneter of the basin. The study showed tha.t approximately 65,000 acre-feet per year left the upper aquifer (sand and grave�) in the Quincy Basin by lateral outflow. Of this volume, the discharge of groundwater through Moses Lake and Rocicy Ford Sprin�s accounted for 56,000 acre-feet per year o�'groundwater discharge, and tl�.e discharge of groundwater through the channel of Crab Creek accounted For an additiona12,000 acre-feet per year. In addition to the above volumes, groundwater discharge from Soap Lake accounted For another 3,000 acre-feet per year o�groundwater discharge. The remaining 4,000 acre-feet per year of groundwater discharge is as underground flow out af the basin (Tanalca, et al., 1974). For t�e lower (basalt) aquifex, the study �ound that about 24,000 acre-feet of groundwater entered the Quincy Basin as lateral grouridwater inflo�v each year and about 40,000 acre-feet leaves the basin by lateral grouridwater outflow each year, with about 5,000 acre-feet per year of ground�vater m.oving from the upper to the lower aquifers. Net recharge fi�oin direct precipitation for both the upper and lower aqui�ers was found by the study to be about 11,000 acre- feet per year. Thus, of the 105,OOU acrel�'eet per year recharge to the basin, approximately 61,000 acre-feet per year left the basiri as surface water discharge and that the remaining 44,000 acre-feet per year of recharge left the Quincy Basin as groundwater flow. Due to all surface waters in the Quincy Basin having been appropriated or withdrawn from availability for appropriation by the Project (Chapter 90.40 RCW) none of the 61,000 acre-Feet of groundwater discharge to surface water sources in the basin was available for. approprzations. Therefore, the only voluzne of naturally occurring groundwater available for appropriation in the Quincy Basin is the 44,000 acra-feet per year of groundwater that flows laterally #'rom tl�e basin. Practically, a volume of grour�dwater that is slightly greater than 44,000 acre-faet per year could be withdrawn and used because of irrigatior�return �lows. The five-year study found that recharge to groundwater from precipitation varied between five and 15 percent of e�fective annual precipitation; that recharge from imigation varied between 15 and 30 percent (adjusted dowtlward by model veri�cation from 19 to 37 percent obtained from field measuremei�ts); and that canal seepage losses were tending to stabilize at about 20 percent as water levels in the upper aquifer rose to near land surface (Tanaka, et al., 1974), Overall, these data sho�v a basin-wide return by deep percolation of irrigation water of about 24 percent of the applied irrigation water. Increasing the �4,000 acre-feet per year of naturally occurring groundwater by 24 percent gives the 54,560 acre-feet per year limit of withdrawal of naturally occurri.ng groundwater in the shallow management unit that is described in the originally adopted form of WAC 173-134-060(1). The five-year study also �'ound that by 1968 there were 2.7 million acre-feet of groundwater stored in the upper (sand and gravel) aquifer, all of which groundwater in both aquifers is from Project activities. After review of the results of the five-year study, the 5tate of Washington concluded that nearly all of the groundwater in storage in the Quincy Basin from project activities could be captured at Potholes Reservoir, and in light of a recalculation by the State of Washington of wlter rights granted for the shallow management unit (57,516 acre-feet per year) that a total commitment of the groundwatar resources of the shal�ow management unit of Quincy Basin was more than the volume of naturally occurring ground�vater available for appropriation. Thus, the Department of Ecology, wlaich had assumed administrative authority over the State's waters in 1970 after its creation by the Legislature, acted to declare a critical groundwater sub-area in the Quincy Basin. This sub-area, as is requzred by statute (RCW 90.44.�30), was defined and its definition rnay be found in chapter 173-124 �VAC (fig. 2). With adoption of the Quincy Sub-area boundaries in Januazy 1973, a problem was created whereby the State of Washington had no authority to issue more rights to ��ublic groundwaters because of the apparent overdra�t on these waters. Additionally, and as stated above, tk�ere is in the statutas no provision for either the State of �Vashirigton or the owner of artit"icially stored groundwaters to authorize the withdrawal and use of the artificially stored groundwaters. Consequently, within the Quincy Ground Water Sub-area, neither the State of Washington nor the Proj.ect had statutory authority for continuing the notice of intention method for licensing withdrawals of groundwater, and a1so, there was no statutory authority for either the State of Washington or the Project to issue rights for the use of artificially stored groundwater, As a result, many water Lisers who had proceeded with development of their land with the contemplation that the use of groundwater would be available through the licensing procedure that flowed from the filing o£the notice of i�tention to construct a well (chapter 50$-14 WAC) found that, although they had made substantial investments in preparation for water use, which waCer use was primarily for iz�-igation, there was no tnethod for obtaining a right to use the groundwater. As a zesult, m��ny water users proceeded to withdraw and use groundwater in the Quincy Basin with no color of right. Because of tlze �rowing use of groundwaCer without color of rigl�t, and because such t�se of groundwater could not be recognized by lending institutions or by power companies supplying power to the well head, a combination ot public pressure and a desire by both State and federal officials to provide a method for use oP sotne portion , of the large amount of arti�'iczally stored �roundwater in the Quincy Basin, a series of meetings between state, federal, county, and private interests began in late 1973. These meetings cul�ninated in drafting a regulation (chapter 173-136 WAC) which acted to establish a method whereby artificially stored ground�vater could be used by a permit system administered by the State of Washington. This regulation �vas intended to cover the conditions of use of arti�cially stored groundtivater that are not set Porth by R23E R24E R25E �26E R27E R28E R29E R3QE R31E La i ' T Ls ort �3 . � DOUGLAS CL � GRANT C0. d o U Soap Lakt Z Z o T .Q � 22 � La°ke� � � N i ._!

To accomplish this goal, two sets of regulatio�s are adopted. The first set of regulations (chapter 173-136 WAC) at WAC 173-136-010 contemplates that there be a permit system that is part of a com�relaensiva State water managemen� and regulatozy control program pertazning to the withdrawal an.d use of groundwaters consisting of commingled artificially stored ground�vaters and public waters located in areas, sub-areas, and zones desig�ated pursuant to RCW 90.44.130. At WAC 173-136-030, the regulations contemplatied that a specific management regulation of the Department of Ecology be adopted for each area or sub-area. Pursuant to this latter section of chapter 173-136 WAC, a series of management regulations for the Quincy Ground Water Sub-area were established by nleans of chapter 173-134 WAC. Prior to final adoption of both chapter 173-136 WAC and chapter 173-134 WAC, the Washington State Department of Ecology, by means of departxnent Docket 74-772, recognized the claim of the United States Department of the Interior, Bureau of Reclarnation to the ownexship of 3,498,000 acre-feet of stored gxoundwater, which volume was calculated on the basis of information supplied by the five-year study contemplated by chapter 508-14 WAC. Some amendments have been made to chapter 173-134 WAC, but, in genez�al, the management regulations �or arti�'icially stored groundwater in the Quincy Basin remain nearly the same as when adopted in January 1975. Exemptions to Water Allocation Policies o�Cha�ter 173--134 WAC As part of the input by federal, state, and county agencies, as well as private individuals, to meetings that culminated.in adoption of chapters 173-136 WAC and 173-134 WAC, tZ�ere�vas cleveloped a cl�scription of the zone within wklich all of the arti�cially stored groundwater claimed by the Un'rted States Department of the Interior, Bureau o P Reclannation was stored. The depth to which this artificially stored groundwater occurred was defined at WAC 173-134-020(10) as the shallow management unit, which by definition extended between land suz'face and a depth of 200 t'eet into the Quincy basalt zone, and includes all of the Quincy unconsolidated zone (WAC 173-124-050(1)), as well as the upper 200 feet of the Quincy basalt zone. The thrust of the or�ginal form of chapter 173-134 WAC was to limit jurisdiction of the regulation to only the sh�llow znanagement unit where artificially stored groundwater was stored and commingled with public groundwaters. Withdrawals from the underlying deep management unit (WAC 173-134•-040(4)) were e:cempt From tl�e original draf� of the regulations (WAC 173-134-050), EXCEPT that t�e regulaCions stated that total withdrativals fxom. the deep tnanagement unit shall not e;cceed 97,901 acre-feet per year pending the outcom.e of further studies by the Dep�u-tment of Ecology. In amendments to chapter 173-134 WAC in 1979, the department extended chapter 173-134 tiVAC to include discretionary authority for the Washington State Department of Eco�ogy to issue public groundwater permits from the deep manageznent unit does not axceed the quantity of water autliorized under public � I � . ; , �� � groundwater permits and certificates for use from the deep management unit (WAC 173-134-160). � In the original draft of the regulations, all withdrawal of waters of the deep management unit were to be controlled by the prior appropriation provisions of RCW 90,44,050, RCW 90,44.060, and related code sectioz�s. The ori�inal regulations stated that total tivithdrativals of ground�,vater from the deep management unit shall not exceed 97,901 acre-feet per year pending the outcome of fiirther studies by the Department of Ecology (WAC 173-134-050). In 1979, this section of the regulations vvas revised to provide the Department of Ecology witl� discretzonazy authority in issuing permits and certificates allowing the �vithdrawal of waters in the deep management unit from a water-bearing stratum, or from water-bearing strata, that are sufficiently distinct �nd distinguishable from the strata of the deep �nanagement unit from�vhich withdrawals are made at the time of amendment. Permits for the withdrawal of grol�ndwater from � the water-bearing stratum, or froxn water-bearing strata in the deep management unit are authorized. to be issued with such tenns or conditions that the De�artment of Ecology deems reasonable or in order to protect existing rights and the public interest, and to provide the Department of Ecology with such information as it deems necessary for the purposes of its nianagemer�t and study of groundwaters in tl�e Quincy Sub-area, inaluding but not limited to such terms and conditions as casing and sealing, logging, metering, and limited well depth. Additiorially, the amended regtilation states that such withdr�wals fi•otn water-bearing stratum, or frozn water-bearing strata, that are sufficiently distinct and distinguishable from strata o�the deep management unit shall not be computed to help datermine the total of actual or authorized withdrawals from the c�eep management unit (WAC 173-135-050 arnended.) Thus, by amending WAC 173-134-050, the Department of Ecology extended the original intent of the regulation to include authorit� over the withdrawal of groundwater from water-bearing stratum, or from water-bearir�g strata, that are su�'ficiently distinct and distznguishable frozxi strata. in the deep managem.ent unit, all of which withdrawals and authority for issuing permits were not stated in chapter 173-134 WAC as originally drafted and adopted in 1975. Other exemption.s to the provisions of chapter 173-134 WAC that are provided for are withdrawals from. agricultural drains, or withdrawals from wells or similar works, of artificially stored groundwaters that are performed for the purpose of removing excess waters injurious to Project lar�ds, to bt�reau canals, wasteways, or other similar facilities (WAS 173-134-090(1)), A second exemptzon to the pez-mit requirements oF chapter 173-134 WAC is the witk�drawal by public ent•ities from wells or similar works of artificially storecl groundwaters that is performed as a necessary incident of tlle operation oF essential public service activity such as solid waste disposal facilzties or the fighting of fires (WAC 173-134-090(2)). A tl�ird exemption to the permit requirements of chapter 173-134 WAC is the �vithdrawals of artificially stored groundwater in amounts of less tlZan 5,000 a day for domestic use (WAC 173-134- 090(3)). . . All oF the above exemptions to the permit rec�uirements of chapter 173-134 WAC, except for the deep management unit, relate to artificially stored grou�dwater that is commingled with public groundwaters. In order to assure continued State jurisdiction over public groundwaters, the original regl�lation at WAC 173-13A�-060(1) provided that thP total quantity of withdrawal.s of public waters from the shallow management unit, whether authorized by permits and certificates issued under RCW 90.44.050, RCW 90.44,060, or otherwise under state law, shall not exceed 54,560 acre-feet per year. This volume of 54,560 acre-feet per year�vas changed to 58,000 acre-feet per year by the amendment t� WAC 173-134-060 that was adopted in 1979. The Factual basis for this change carmot be determined using available data, Both the original regulation and the amendment to the regulation provide Eor the withdra�val of relatively small amounts of public groundwaters that are in the range of not more than 4,000 acre-feet annually, and which should be available For appropriation in the shallow management unit. These small amounts oF groundwater are reserved by chapter 173-134 WAC for domestic uses, including witkidrawals for group domestic uses. The factual basis for the 4,000 acre-foot per year limitation placed on the small amounts of public ground�vaters authorized by WAG 173-134- 060(1) For withdrawal for group domestic uses in relinquishments of grouridwater rights that corne to the Department of Eco�ogy between approximately October 1974 and January 1975 when. the regulations were adopted. These r.elinquishxnents cazne about because of a request by the Department of Ecology to all record known right ' holders in the Quincy Sub-area to install metars on their wells. The request was not in tl�.e form of an order, but was intended to obtain public compliance with tha department's ef:Cort to measure the total withclrawal of groundwater from the Quincy Sub-area to find if these withdrawals were 54,560 acre-feet per year from the shallow managemen�unit and 97,901 acre-feet �er year from the deep management unit, limiting voltunes that are described in the original regulations. Without some measure o�total annual g�'oundwater withdrawal authorized by permits and cez-tificates in the Quincy Sub-area,there could be no assurance that withdrawals were not exceeding the limiting volumes, or more importantly, that groundwater withdrawals were not reaching the limiting volumes, in which additional permits for the wit�ldrawal oE public groundwaters could be granted by the authority of RCW 90.44.050. Public reaction to the request varied widely with. some water users immediately installing meters on their tivells, others forming political pressure groups to have the department �vitl�draw the request, and still others, primarily tl�ose who did not use the groundwater authorized by their pez-mits, relinquishing the�ermit to the Department of Ecology so they would r�ot liave to buy meters. It is this latter group that is the factual basis for the 4,000 acre-foot per year a�gz'ouncl�vater that was available in 1975 For fizrther appropriation from. the shallow management unit. Since 1975, pezmits for approximately 1,000 acre-feet of the 4,000 acre-foot volume ha.ve been issued ir� the Quincy Basin for yroup domestic use. All of these permits are #'or with.drawal of groundwater only from the shallow managerne�nt unit. An additional volume of gz�oundwater not addressed by the regulations and therefore exempt From them is irri�ation retunz flow frorzl ground�vater pumping from the deep � . management unit, If the 24 percent irrigation returr� flow value is applied to recharge to the shallow management unit from groundwater withdrawals from the deep management unit, the total a�nount of groundwater that can be withdrawn from the shallow manageme�t unit can be increased by approximately 23,500 acre-feet per year when all of the groundwater rights authorized for withdrawal from the deep management unit (97,901 acre-feet per year) are exercised. Using the above reasoning relating irrigation return flow and relinqt�ished water rights, the department regulations �vere drafted to p.rovide for a 4,d00 acre-foot per year value for the relatively small amounts of public groundwater that are available for appropriation in the shallow management unit (WAC 173-134-060(1)). The aforesaid value of 4,000 acre-feet per year probably represents an extremely conservative measure of the additional volume of naturally occurring groundwater available for appropriation and use from the shallow management unit in 1975. In all probability, the 1979 amendment to WAC 173-134-060(1) that increases the volume of riaturally occuning groundwater that can be withdrawn from the shallow management unit frozn 54,560 acre-feet per year to 58,000 acre-feet per year is an attempt by the Department of Ecology to move away from the earlier conservative estimate of the additional vol.ume of groundwater that is available for appropriation from the shallow management unit. Until there is some zneasurement of the annual volume of groundwater withdrawal and use by permits and certificates issued pursuant to RCW 90.44.050 and RCW 90.44.060, no further changes shol�ld ba anticipated in the 4,000 acre-foot per year volume of groundwater in the shallow management unit that was av�i.lable for appropriation and use in 1975. ��. ADDIT'IONAL DATA F'ollowing ldoption of chapter 173-134 WAC in January 1975, the Washington State Department of Ecology, in cooperation with the United States Department of the Interior, Bureau of Reclamation (now Water and Power Resour.ces Service), drilled a test well at the west quarter corner of Section 15, Township 18 North, Range 25 East, W.M., for the purpose of evaluating the efFectiveness of 200 feet of basalt in isolating the major portion of the artificially stored ground�vater stored in the Quincy Sub-area as a result of Project activity from deeper groundwater. This test well was designed so that the casing extended from land surface to 200 feet into the basalt and the remaixling portion oF the test well was uncased. Surrounding the test well, several shallow r,vells were drilled through the sand and gravel and to the de�tli of the top of the basalt. Following a 24-hour pump test, it was determined that withdra�vals of groundwater in wells developed in the basalt, but with the top 200 feet of basalt cased, had no effect , on gY•oundwater movement in the overlying sand and gravel. From this evidence, it appears that groundwater withdrawn from the daep management unit will not have an immediate impact on commingled artificially stored and public groundwaters in the sand and gravel and upper part of the basalt. Tn 1977, the town of Ephrata drilled a deep water-supply well under the authority of existing groundwater permits and certificates. This well, which is 1,860 feet dee�, is the deepest stratigraphic penetration by any water well in the Quincy Ground Water Sub-area. The Washington State Department of Ecology, in cooparation with Washington State University, made electric borehole logs of the City of�phrata Wel�, Using the gamma ray log, which �og measures the natuz�al radioactive character ot' rocics penetrated by the well, an excelle7lt correlation can be made between deeper rock units penetrated by the City of Ephrata Well and the Basalt Explorer No. 1, an old test well that has been maintained by the Washington State Department of Ecology as a water-level observation point in the Udessa Sub-area (fig. 3). Deep stratigraphic correlation's were used to define groundwater zones by the Odessa Sub-area Management Policy Regulations (chapter 173-130 WAC). Hez�e, the subsurface rocics were broken into three major units, "Zone A", "Zone B", and "Zone C" (WAC 173- 130-030). As de�'ined iz�. the policy regulations, "Zone A" includes all rocics between land surface and the bottom of tl�e zone o#'porosity shown at an a�titude of 60 feet above nlean sea level in the well known as the Basalt Explorer No, l, which well is located in the W%zW'/Z of Section 10, Township 21 North, Range 3� East W.M. (WAC Z73-130-030(1)). "Zone B" includes all rocks lyi�g between an altitude of 60 feet above tnean. sea level and an altitude ot'300 feet below mean sea level in the Basalt Explorer No. 1 (WAC 173-130-030(2)). "'Lone C" includes all rocks lying below an altitud.e oF300 feet below mean sea level in the Basalt E;cplorer No, 1 (WAC 173-130- 030(3)). As can be seen. on Figure 3, the rock units penetrated by the City of Epllrata Well correlate�vith the stratzgraphic features used to define "Zones A", "B", and "C" in the Odessa Ground Water Sub-area Management Policy except tllat the elevation above mean sea level for the bottom of"'Lone A"/top of "Zone B", botton�. of"Lone B"/top of"Zone C" in the City of Epku�ata Well is different.

Additionally, 1s is shown on Fi�ure 3, the thickness of "Zone B" in the Basalt Explorer No. 1 is approximately 300 feet whila in the City of Ephrata Well, "Zone B" equivalent is only 260 feet thicic. Consequently, due to the decreased thickness of"Zone B" equivalent in the City of Ephrata Well, the top of "Zone C" in the City of Ephrata Well is 270 feet below mean sea level while in the Basalt Explorer No. l, the top of"Zone C" is 240 feet below mean sea level. Also shown on Figure 3 is an electric borehole log of the Bud King Well located approximately five miles northwest of the Basalt Explorer No. 1 and slightly more than 25 miles northeast of the City of Ephrata Well. Although the King Well does not penetrate the full thickness of"Zone B", there is good correlation of rock units in the lo�er part of"Zone A" between the I�ing Well, the Basalt Explorer No. 1, and the lowei�part of"Zone A" equivalent in the City of Eplzrata Well. Features such as the �eneral change in elevation of the bottom of"Zone A", the thxckriess of"Zone B", and the elevation of the top of"Zone C" sh.own on Figure 3 can be explained by re�ional geologic trends of the basalt from the Quincy Baszn eastward to the main part of the basalt plateau where the Basalt Ex�lorer No. 1 is located. The general dip of the basalt beds in the central part of the p�ateau where the Basalt Explorer No. 1 is located is toward the south and west at a very gen.tle slope. Conversely, the dip of the basalt beds in the Quincy Basin is southeasterly from the Beezley Hills, easterly and southeasterly from the Evergreen Ridge area, and north and northeasterly From the Frenehrrian Hills. Due Co the contrasting directions of dip between basalt rocics in the Quincy Basxn and basalt rocks in the main part of the basalt plateau, differences in elevation between corrasponding electric log features oF rocic u.nits shown on Figure 3 for the Basalt Explorer No, 1 and tha City of Ephrata Well should be anticzpated. - Groundwater management regulation adopted for the Odessa Sub-area (cha�ter 173- 130 WAC) specifically established a procedure for managing groundwater in "Zone A" only (WAC 173-130-040). Subsequently, it has been Department of Ecology policy to freely grant permits for the withdrawal of groundwater from. "Zone C" in the Odessa Sub-area, all oFwhich permits are conditioned so that groundwater in "Zone A" of the Odessa Sub-area is cased out of the "Zone C" well. Although the 1979 amandments to cllapter 173-134 WAC do not specifically address the possible correlation of"Zone C" of the Odessa Sub-area with water-bearir�g rocks at depth in the Qt�i.ncy Sub-area, woxding added to WAC 173-134-050 gxants the llepartnnent of Ecology discretionary authonity zn issuing permits and certificates allowing the withdrawal of waters in the deep management unit from a water-bearing stratum, or from water-bearing strata, that are sufficiently distinct and distinguishable fxom the strata of the deep znanagement unit. Furthermore, the amended wordin� authorizes the department in issuing such pennits to condition the pertnits to include provisions for casing and sealing, logging, metering, and limiting well depth. The amended wording oP WAC 173-134-050 also provides that withdrawals from the water-bearing stratum, or from water-bearing strata, that are suFficiently distinct and distinguishable fxor� the ' . strata of the deep management unit shall not be computed to help determine the total of actual or authorized volunne of withdrawals from the deep management unit. It would appear from the above conditions that the department of Ecology is aware of � the probable co�-relation of"Zone C" of the Odessa Sub-area with deep gzot�nd�vater in the Quir�cy Sub-area, and is providing a rneans in the regulations for deep wells to be drilled in the Quincy Sub-ar�a for the purpose o�fiirther confirming this correlation. Further support of this supposition is the addition to the Quincy Ground Water Mariagement Re�ulation in 1979 of section WAC 173-134-160 which authorizes unused public groundwater in the deep m.anagement unit to be withdrawn and used at the discretion of the departm.ent so long as the total withdrawal from the deep management unit does not exceed the 97,901 acre-feet per year set forth in WAC 173- 134-050. The department, acting under this latter amendment to chapter 173�134 WAC, has issued permits for the withdrawal of public groundwater frorr� the deep managennent unit since amendznent to the regulations in 1979. Tssuance of these permits has been extremely selective and tal�es into account such matters as the highest feasible use of the identified waters and gives regard to policies regarding water allocation�hat are found in chapter 90.54 RCW. An evaluation of the volume of rights in both the shallow and deep management units by the Department of Ecology and predecessor agencies by th.e end of 1972 sho�vs the following: Lands with Lands without �'roject Water Project Water Total in Certificates Allotment Allotment 1972 and Permits ac,-ft.l (ac.-ft,) ac.-ft. Sllallow Management Unit 14,140 �- 43,376 57,516 Deep Management Unit 27,?06 70,695 97,901 TOTAL 41,346 114,071 155,417 This e�c�aluation shows the total withdrawal of groundwater frozn the deep man.agement unit is potentially 97,901 acre-feet per year, tha same value that is set fortk� as the limit of witl�zdrawals of groundwaer from the deep management unit WAC 173-134-OSO. Assuining that lands witl� Project water allotment will not normally use the �ull allocation of their right to groundwater because Project water must be paid for iE�used or not, it seems reasonable to assume that a znaximum. of 27,206 acre-feet of groundwater from. the deep tnanagement unat can. be available for'furthex appropriation without exceeding the 97,901 acre-feet per year limitation i:mposed by the regulations. This is not to say, however, that the existing pernnits and certificate, though unused, must be first forfeited before additional pern�its and certificates can be issued. At RCW 90.14.140, where sufficient cause of non-use of water rights is defined, tlie definition takes the form of rights exempted from the forfeiture provisions of chapter 90.14 RCW. One of the rights exempted under suf�cient cause definition is a right to water that is a standby or reserve water supply to be used in time of drought or other � low-flow periods. The statute goes on to say that to maintain the exemption, the witl�drawal or diversion facilities of the right must be maintained in good operating � condition for the use o�such reserve or standby water supply (RCW 90.14,140). An evaluation by this investigation of the basic data used to com�ile the value of 27,206 acre-feet per year of groundwater authorized for withdrawal from the deep management unit for use on lands wit11 Project water allotments shows that, due to various factors, not all of this groundwater is available for appropriation. A tabulation of the remaining unrelinquished or concealed rights originally used to arrive at the 27,206 acre-foot per year value fbr tha deep management unit is shotivn on Table 1. By comparing the records of the Project�vith the tabulated rights appea�ing on Table l, it was found that approximately 4,156 acre-feet of these rights are appurtenant to lands which, upon close inspection, do not receive Project waters. As a consequence, a revision of the tabulation of Sate rights appurtenant to lands that receive Project waters is shown on Table 2, and the n�aYimum volume of these ri�hts is 16,981 acre- feet per year. The general location of lands appurtenant to these rights is sho�vn on Figure 4. This volume, then, would be the maximum volurne of additional rights that could be issued b�the State of Washington under the provisions of chapter 173-134- 160 RCW. The real value of the righ.ts from the deep management unit that can ba issued pursuant to chapter 173-134-160 WAC can only be determined after field checics to determine the actual volume of use for rights shown on Table 2. Rights suck� as that of School District 161 (Well 19, T�ble 2), Greenvier�v Water Association (tiVell 22, Table 2), Wheeler Water Association (Well 24, Table 2), Pronto Foods, Inc. (now Carnation Corporation (We1124, Table 2), and the Washin�ton State Department of I�ighways (We1131, Table 2) will probably be fouzld to be used to the fiill extent of the right. No additional rights could be issued by the State of Washin�ton fox the volume of groundwater withdrawn and used each year by each of thP i-ights shown on Table 2. � ; I � � . j � , � � ; TABLE 1 - Remainjrg active rjghts to gro�ndwater from the deep management unit that were used ` to determine vol.�me of State rights appurte7ant to lands that receive Project waters.

The three categories and tests and data needs are as follows, 1. Groundwater quantitX. The quantity of groundwater in the shallow management unit was assessed by the U.S. Geological Survey in its five-year study completed in 1972. Quantitative value for groundwater in the shallow management unit was derived from this study and is set forth by regulation at WAC 173-134-030(a). This volume, 57,560 acre-feet per year, is calculated on the basis of average annual recharge to the shallow managem.ent unit from natural sources and irrigation return flo�v to the shallow management unit from groundwater withdrawal by the authority of State permits from the shallow manageznent unit. The five-year study by the U.S, Geological Survey did not, however, quantify the volume of grotmdwater that can be �vithdrawn from the deep management u�it, To date, two tests have been made of groundwater quantity in tha deep znanagement unit, but these test data have not been utilized to quantify the amount of natural annual recharge to the deep management unit. Analysis of existing data obtained from we11s that penetrate the deep management unit can be added to data obtained from the two tests and used as a method for deterrnining tha average annual recharge by natural sources to the deep management unit. This recharge value, though unlcnown at present, can be used to evaluate it'ground�ater withdrawal in tha amount of 97,901 acre-feet per year authorized by WAC 173- 134-030(b) exceeds recharge a�d to formulate a policy for management of groundwater in the deep znanagemant unit of the Quincy Sub-area. In th� event that withdrawals exceed natural annual recharge to the deep management unit, a policy for water management similar to that formulated for the Odessa Ground Water Sub-area and set forth in chaptez 173-130 WAC can be developed foz'the deep management unit in the Quincy St�b-area. A. Ti� addition to quantifying tk�a amount of groundwater available for withdrawal and use within the deep rnanagennent unit, tests sk�ould be made to identify the presence of a deep �vater-bearing unit in the Quincy Ground Water Sub-area that correlates with "Zone C" of the Odessa Ground Water Sub-area. To date, only one well, that of the City of Ephrata, has tapped tilis deep goundwater supply that may be a water-bearing stratum, or�,vater- bearing strata sufficiently distinct and distinguishable from the deep manageme�t unit to qualify as a separate management unxt :For the Quincy Sub-area under the authority of WAC 173-134-OSO. A zninimum of one, and if possible two, deep test well should be drilled to con�rm the presence � of tl�.e Quincy Sub-area of a unit equivalent to "Zone C" of the Odessa Sub- � area. One possible location for a test tivell is near the city oFMoses Lake, where a municipal water supply well is no�v bein� drilled. For test j � i , purposes, the municipal water-supply well could be deepened to identify the presence oF"Zone C" equivalent at that location. Electric borehole logs are the best means for id.enti:Fying rocic units overlying Zone C. The deepened municipal well could be logged, and a pump test made of the well while the deepened portion of the borehole is open for�roundwater withdrawal. After testing, a piezometer could be installed in the deepened portion of the well for the purpose of monitoring water levels in the "Zone C" equivalent strata and the deepened portion of the municipal well plugged. Water-level monitoring of the isolated deep strata will provide hydraulic information to confirm the separation of the deeper strata from the overlying aqui�er ir�the deep man�gement unit. An additional test site could be near the town of , Ql�incy�vhere there is now contemplatad a deep water production well. The same testing procedures as described above for the testing of deep water- bearing strata at Moses Lalce could be carried out at the proposed town of Quincy water supply well. B. Using information that can be obtained from the piezometers proposed for installation in the two daep test wells, an evaluation can be made of the poter�tial for obtaining low-grade energy from groundwater in the deep strata that correlates with "Zone C" of the Odessa Sub-area. At present, the city of Ephrata has applied for and received a �rant from the U.S. Department of Energy for the purpose of invastigating use of Warm�ater from the new city of Ephrata well that penetrates the rock unit equivalent to "Zone C" of the Odessa Sub-area. With proper monitoring o�water temperatures in the two test wells proposed above, it is highly probably that the temperature of ground-water in isolated "Zone C" equxvalent that may be penetrated by the deep tests will be found to be higher than water in the new city of Ephrata well due''t.o commingling of"Zone C" equivalent water with groundwater in the deep tnanagernent unit in tl�e city of Ephrata well. I�'this energy source is found to be viable, municipal wells penetrating "Zone C" can supply not only �roundwater for municipa� needs, but low- grade energy for heating an operation of azr conditioi�units, The multiple purpose aspect o�groundwater usage From `Zone C" equivalent iz� the Quincy Sub-area would thez•eby be enhanced. C. �valuation of withdrawals from tnanagement units. As a consequence of the many�vells that have been dr�lled in the Quincy Ground Water Sub-area after adoption of chapter 173-134 WAC iz� 1975, new data have become available ori the configuration of the elevation of tl�e top of the basalt. As defined in WAC 173-134-020(10), the shallow management unit is con.tinuous between land surface and a depth of 200 feet into the Quincy basalt zone and includes all of the Quincy unconsolidated zone. The preliminary evaluation of the managemen.t unit from which. State rights have been grar�ted, and wkiich was made in 1973, should be reassessed now that better�vater-rigkzt records are available and more precise information is available about the elevation of ground�vater withdra�vals from the shallow :� : : and deep management units, the top of the basalt aquifer was detennined , from a map appended to water Supply Bulletin 8 (Walters and Grolier, 1960, plate 3). Well log information For each�vell serving a water right was classified according to the management unit on the basis of the aforesaid map. An update of the top of the basalt map should provide m.ore acct�rate values on depth of penetration to the top of the basalt and therefrom a more accurate classification of rights from the shallow and deep management units that are perCinent to public groundwater. D, Field check of unused water rights. A field check should be made to determine the quantity of groundwater withdrawals now ongoing and authorized by State permits and certificates that are appurtenant to wells from both the deep and shallow management units in the Quincy Sub-area. Unused rights, when determined, can be the basis for issuance of additional rights to groundwater frozn deep and shallow management units to assure that tk�e entire volume of public groundwaters authorized for withdrawal by . WAC 173-�34-050 and WAC 173-134-060 are withdra�vn and used. 2. Groundwater c�ualitv. Tests to evaluate the quality of groundwater in the deep and shallow management units should be brol<en into two general phases as follows: Phase 1 - All water c�uality data available �or groundwater in the Quincy Sub-area should be evaluated to determine the overall quality and any changes in the quality of groundwater in the shallow management unit as a result of deep percolation of irrigation water applied tl�rough the water-delivery facilities of the Columbia Basin Project. In general, both organic and ino�ganic parameters for water-quality data should be evaluated. Tnorgani.c paxameters should include at a miniznum nitrate, phos�hate, specific conductance and total dissolved salts, chloride when the total dissolved salts are greater�han 500 mg/l, and arsenic which is often associated with various types of crop management chemicals. Organic parameters sh.ould include an evaluation of the bacterial content of the groundwater and a determination of the concentration of herbicides, pesticides, and insecticides in groundwater o�the shallow management unit. As a standard for evaluating the groundwater of the deep and shallow management units, the water quality data-source well should be identi�ed according to management unit, the date of the sample, and the natne o�the laboratory that made the analysis. Using tlie above information, data can be portrayed as contours of equal value for each constituent for each management unit. This informatzon can be used to identify areas where the quality of groundwater in both tY�e deep and shallow n-�ana�ement units does not meet drinking water standards, and more ir�:iportantly, these data can be used to identify areas wheze ground�vater in the deep and shallow management units does meet drizilcing water star�dards. i , , . Phase 2 - On the basis of data derived from Phase 1 described above water-quality monitoring prograxns should be established for the shallow and deep rnanagement ' tinits as well as for "Zone C" equivalent strata. The monitoring program should be designed to determine any deterioration of groundr,vater quality in the shallow and deep management units where the Phase 1 investigation may show groundwater quality to be of acceptable drinking water standards. The .frequency of sampling for the monitoring program should be not less than once each year, and the constituents to be analyzed for as part of the monitoring program shot�ld be both the inorganic and organic compounds described for the Phase 1 water- quality investigation. The water-quality monitoring program for the deep strata equivalent to "Zone C" from the Odessa Sub-area could be carried out using piezometer tubes recommended for installation in the wells drilled to test the presence and watar yield of th� strata. Water-quality samples could be obtained on a periodic basis of not less than once each year from the piezometer tubes. These data will provide information about the quality of ground�vater available from the deep strata equivalent to "Zone C" of the Odessa Sub-area, and can be used to determine if this source o�groundwater is a potential supply for municipalities in the Quincy Sub-area. 3. F'uture Sources of Groundwater. Future sources of groundwater supplies for municipal t�se can be assessed using factual information developed by the above testing procedure. At preser�t, general�data available indicate that quality oF groundwater in the deep management unit can meet public drinking watar standards and therefore can serve as a source of supply to municipalities. However, prior to determining the viability of use of groundwater from the shallow management unit as a source of stipply for municipal, the water-quality investigation described above should be completed. Using water-quality data and information on the quantity of groundwater available for appropnation and use beyond thosa c�ualities prese�tly being withdrawn, future sources of water supply for znunicipal, industrial, and agric«ltural purposes can be identz�'ied. I� additzon to groundwater in the shallow and deep tnanagement units, tl�e above testing procedures and data requirements can be used to evaluate tlze quality and yield of groundwater from the deep strata in the Quincy Sub-area that is eqt�ivalent to "Zone C" of the Odessa Sub-area. Tl�is factual material will provide a basis for formulating various alternatives for the Grant County Coordinated Water System Plan to anticipate future deznands on the groundwater system in the Quincy Sub- area for all purposes. LEGAL AND FINANCIAL CONSTRAINTS ON FUTURE DOMESTIC WATER NEEDS One of the general declarations of Fiindamentals for utilization and management of waters oFthe State of Washington set forth at RCW 90.54.020(7) is the encouragement of the development of water-supply systems, whether publicly or privately owned, which supply water to the public-generally iz1 regional areas r,vithin the state. Additionally, at RCW 90.54.020(4), the statute sets forth another general declaration of filndamentals for utilization and management of waters of the state and provides that adequate and safe supplies of water shall be preserved and protected in potable condition to satisfy human domestic needs. Using these two fundamentals oF chapter 90.54 RCW and the incidence of deep percolation of irrigation water in the Quincy Basin, it appears tl�at the basic statutory guidelines are present for the reservation of vol�.�mes of groundwater from the deep management unit in the Quincy Basin for use by domestic users. Additionally, and somewhat supportive of this view, is WAC 173- 134-160 which requires the Departznent of Ecology, when issuing additional permits for withdrawal of groundwater from the deep management unzt, to take into account maCters such as the "hzghest feasible use of'the water." tiVithout a cleax definition of "highest feasible use of the water," there is a possibility that the conflict between domestic water use and use of water from the deep mana�ement unit for irrigation purposes will cloud the issue of"highest feasible use" of water from the deep management unit. Although the above-cited provisions of chapter 90.54 RCW apply to all waters of the state, the Departmes�t of EcoZogy has reserved only 4,000 acre-feet anz�ually from the shallow management unit for domestic uses. If the 24 percen.t irrigation return flow factor is applied to tha maximum of 97,�901 acre-feet per year withdrawal from the deep management unit authorized by WAC 173-134-050, or an amended volume found to be valid as a result of Test 2 recomxnended above, a st�bstantially larger unappropriated volume of water from the shallow management unit becomes available. At present, in chapter 173-134 WAC there does not appear to be any legal method for issuing nights �or this additional voluzne of water, or for designating whether this additional water should be �or irri�ation or for domestic use. , Considering water-quality factors that are related to changes in the quality o f corruningled public and artificially stored groundwater in the shallow znanagetnent unit, it is reasonable to assume th.at the best quality water for domestic use would come either from the deep mana�ecnent unit`or from the deep water-bearing stratum, ar from water-bearing strata, that is contemplated by WAC 173-134-050. An equivalenC "Zone C" water-bearing unit in the Qux�cy Sub-area should fulfill tl�e wording, and the intent, ot'the "distinct and distinguishable" portion of WAC 173- 134-050. Consequently, the best source of domestic �vater in the Quincy Sub-area has not been specifically reserved �'or domestic use, nor has any volume of groundwater been specifically reserved by regulation for domestic use from the deep mana�ement unit or the "distinct and distinguishable strata." Instead, the regulations have reserved , � a small amount of groundwater from the sh�llow m�nagement unit for domestic purposes, but sltch waters may have had quality changes due to the commingling oF irrigation return flows with public groundwater. For reasons cited above, there appears to be some legal constraints to meeting future domestic water needs o�'Grant County with groundwater of a quality that is compatible with domestic use. Some amendment to chapter 173-134 WAC would be required to make the needed char�ges, An offer of the issuance of additional rights to groundwater for irrigation uses from the shallow management unit to account for deep percolation of groundwater withdrawals �rom the deep management may serve to obtain the support of irrigators for the needed changes in the regulation. The aconomic burden of drilling a water-st�pply well to intercept water-bearing stratum in "Zone C" equivalent in the Quincy Sub-area would eliminate most small water purveyors. Only the larger communities in Grant county, such as the city of Moses Lalce, the city of Ephrata, and possibly the cities of Warden and Royal City, could have the funding available to drill to the depths required and to install casing that will probably be reqt�ired by the Department of Ecology, In one sense, the depth and cost for obtaining groundwater from "Zone C" equivalent in the Quincy Sub-area will resolve the possible conflict between domestic and irrigation r�vater tisers from that source. In the Odessa Sub-area, only five "Zone C"perznits have been granted by the Department of Ecology and wells drilled since "Zone C" was first described by regulation in January 1974. "Zone C"wells that have been drilled in the Odessa Sub- area for irrzgation have not proven to be greatly successful as a source of groundwater for irrigation as a result of the high cost of well construction and the rate of fall of the water level in "Zone C" wells, which rate of fall is equal to or greater than the rate of fall of water levels in "Zone A" wells. If adec�uate testing ot'"Zone C" equivalent groundwater in the Quincy Basin is provided, municipalities wishing to construct "Zone C" tivells could pay substantially greater costs for the supplies of good quality water, and can afford the cost of proper supervision of well drilling and tiesting. Additionally, the lower total draft of groundwater from a "Zone C" equivalent in the Quincy Sub-area would be less than the rate of draft of groundwater for �rrigation use from the same zone. .
