This wastewater discharge permit is hereby granted by the City of Moses Lake, Washington, referred to as the City, to Grant County
Fair Grounds referred to as the Permittee. This permit authorizes Permittee to discharge wastewater from the permittee's Facility into
the City's POTW in accordance with the conditions contained within this permit. The permit becomes effective as of the date signed
by the City.
GENERAL CONDITIONS
1. All discharges and activities authorized herein shall be consistent with the terms and conditions of this permit. The discharge
of any pollutant not authorized by this permit shall constitute a violation of the terms and conditions of this permit.
Whenever the Permittee refuses to take corrective action or continues a violation, the imposition of civil penalties or
termination of this permit may result, or both. Termination of this permit may require disposal of the wastewater in some
manner other than into the private sewer or to the City's POTW, at the expense of the Permittee.
2. Nothing in this permit shall be construed as excusing the Permittee from complying with any current federal, state, or local
statutes, ordinances, or regulations.
3. All facility changes that may result in a significant deviation in character of pollutants discharged to the POTW, from that
herein specified, shall be reported to the City. Significant adverse deviations in character of pollutants shall be authorized by
the City before discharge to the sewer system. No significant change shall be made until plans have been approved by the
City, and a new or modified permit has been issued. No new connections, increased flows, or significant changes in
wastewater characteristics are permitted that will cause violation of the effluent limitations specified herein.
The diversion or bypass of any discharge from any pre-treatment facility utilized by the Permittee to maintain compliance
with the terms of this permit is prohibited except where unavoidable to prevent loss of life or severe property damage. The
procedure outlined in paragraph four (4) of these General conditions shall be followed in the event of such a diversion or
bypass to the City's POTW.
4. In the event the Permittee is unable to comply with any of the conditions of this permit because of a breakdown of equipment
or facilities, due to actions on the part of the Permittee, the Permittee shall perform the following actions:
a. Immediately stop, contain, and clean up the unauthorized discharge and correct the problem.
b. Immediately notify the City so steps can be taken to prevent damage to the POTW.
c. Submit a written report within fifteen (15) business days of occurrence, describing the breakdown, the actual
quantity and quality of the resulting waste discharge, corrective action taken, and the steps taken to prevent a
recurrence.
d. Pay reasonable costs incurred by the City that are associated with a breakdown, accident, or other cause that can be
demonstrated as attributable to such event.
Any permit noncompliance constitutes a violation of chapter 13.05 of the Moses Lake Municipal Code and is grounds for
enforcement action in accordance with that code.

compliance with the conditions of this permit, or the resulting liability for failure to comply.
6. The Permittee shall adequately maintain and efficiently operate all treatment or control facilities or systems installed or used
by the Permittee to achieve compliance with the terms and conditions of this permit.

hearing before the City Council. If the City Council determines a violation has occurred, the permit may be amended,
suspended, or revoked in whole or -in part.
a. Violation of any terms or conditions of this permit.
b. Obtaining this permit by misrepresentation or failure to fully disclose all relevant facts.

a. Enter that portion of the premises by escort where an effluent source or disposal system is located or where records
are required to be kept under the terms and conditions of this permit.
b. Inspect monitoring equipment or monitoring methods required by this permit.
c. Sample discharge of pollutants.

by the Permittee in the rate structure. The City may set forth the various fees in a separate ordinance.
11. The Permittee shall make application for permit renewal at least 180 days prior to the expiration date of the permit. In the
event that the City does not respond within the allotted 180 day period, the existing permit shall remain in force until the

Moses Lake. The City may revoke this permit if the permit fees are not paid.
Effluent Limits
During the period of this permit, the Permittee is authorized to discharge wastewater to the POTW subject to the specified flow,
concentration, and monitoring requirements. Wastewater shall be monitored and discharged to the POTW and shall not exceed the
maximum daily flow of 80,000 gallons per day. The effluent limitations for the discharge to the POTW are shown in Table 1: Effluent
Limits Outfall 001 (Facility's Sampling Manhole).
Effluent characteristic limits not listed in this permit are set forth in Chapter 13.05, Wastewater Regulations, City of Moses Lake
Municipal Code.
In order to meet the effluent limitations, the Permittee shall provide facilities as specified herein. When required, pretreatment and
storage facilities shall be designed and operated by the Permittee in a manner such that the wastewater discharge to the POTW
complies with the effluent limits. During emergency conditions, or when the effluent does not meet the conditions of this permit, the
Grant County Fair Grounds Industrial Waste Discharge Permit No. 25

Permittee shall divert the flow, collect the wastewater, and re -treat the effluent. If the permit effluent limitations cannot be achieved
by the onsite treatment system, the effluent shall be collected and sent off site for disposal in accordance with applicable regulations.
Beginning on the issuance date and lasting thru the expiration date of this permit, the Permittee is authorized to discharge wastewater
to the City of Moses Lake POTW subject to the following limitations:

a. Maximum Daily effluent limit means the highest allowable daily discharge. The daily discharge means the discharge of a
pollutant measured during a calendar day. For pollutants with limits expressed in units of mass, calculate the daily discharge as
the total mass of the pollutant discharged over the day [lbs/day = (concentration mg/1) x (flow gpd / 1,000,000 ) x 8.34] . For color and pH,
the daily discharge is the average measurement of the pollutant over the day. For temperature, no single measurement shall
exceed 104°F.
Monitoring Requirements
The Permittee shall monitor the wastewater and production according to the following schedule in Table 2: Monitoring Requirements Final
Wastewater Effluent Outfall #001 (POTW).

volume at time intervals proportional to stream flow); or collected by increasing the volume of each aliquot as the flow increased while maintaining a
constant time interval between the aliquots.
Constituent: Any of the pollutants or potential pollutants found in the wastewater.
Effluent Limits: Flow, concentration, pH, and mass loading limitations for wastewater discharged to the POTW by the Permittee.
Monitoring: The program of flow and constituent determination outlined to ensure compliance with the effluent limitations and to define the flow and
constituent levels in an expanded scope for the wastewater discharged to the POTW.
Permittee: Grant County Fair Grounds
POTW: The system of gravity sewers, force mains, pumps stations, and sewage treatment plants owned by the City of Moses Lake.
Wastewater: Water discharged as a by-product of any of the various industrial processes.
