Background
The County has identified the need to develop a new solid waste disposal option by 2032 to replace
the existing operating landfill (New Landfill). This option could consist of either a future landfill or a
new transfer station with the long haul of waste to an out -of -county landfill.
Parametrix previously provided support to revise the Solid Waste Management Plan (SWMP)
narrative and recommendations to better define the scope of the Disposal Options Study and
eliminate the need for a SWMP amendment to implement the Disposal Options Study
recommendations. Parametrix also provided the SWMP cost assessment based on revised
recommendations.

ParametriX
Scope of Work
Parametrix initiated the Long -Term Disposal Options Study effort under the FY 2022 amendment and
continued effort under the FY 2023 amendment. This included draft development of options for
siting and developing a new in -county landfill and contracting for long-haul and disposal at an out -of -
county landfill. The Long -Term Disposal Options Study will be further advanced under the
FY 2024 Amendment.
Subtask 6.1- Disposal Options Study
Complete the Disposal Options Study to evaluate future disposal options to include two options:
Siting and developing a new in -county landfill. This option would include:
—� Siting and developing a new, limited -access, mixed solid waste landfill. A limited -access
landfill is one that is closed to the general public and is accessed only by haul trucks
from County transfer stations/drop boxes, close -proximity collection route trucks, and
other approved high-volume haulers.
—� Developing a transfer station/drop box system to support the new limited -access landfill.
Contracting for long-haul and disposal at an out -of -county landfill. This option would include:
—� Siting and developing a new transfer station with capacity to accept all County waste for
loading of long-haul trailers. This option would assume a haul long enough to necessitate
the use of a compactor to provide denser loads for more efficient refuse hauling. The
nearest regional landfill is the Greater Wenatchee Landfill in East Wenatchee, which is
45 miles from Ephrata Landfill
p (presumed location of transfer station). Hauling this
distance would benefit from waste compaction.
—� Conducting a disposal procurement process to obtain competitive bids for long-haul
trucking and disposal. This option could also consider public or private operation of the
transfer station.
The Disposal Option Study will provide critical input to the long-term funding planning for the solid
waste system, including high-level cost and greenhouse gas considerations.
Follows SWMP cost assessment and takes 3 months, including County determination of preferred
option. (Complete in June.)
Subtask 6.2 - Capital Cost and Operation Costs Funding Plan
Develop a capital cost and operation costs funding plan (Funding Plan) for solid waste facility
development and operations based on the findings of the Disposal options Study and current solid
waste system obligations. This Funding Plan will inform the rate study work to be conducted under
Subtask 6.3. Elements of the Funding Plan will include:
■ Old Ephrata Landfill Model Toxics Control Act (MTCA) Mitigation*.
■ Old Ephrata Landfill Post -Closure Care*.
■ New Ephrata Landfill Phase 4 Development.
■ New Ephrata Landfill Closure*.
■ New Ephrata Landfill Post Closure -Care*.

Overlaps Subtask 6.1 by 1 month and takes 2 months. (Complete in July.)
Subtask 6.3 - Rate Study
Scope of Work
Subconsultant FCS Group, under contract to Parametrix, will develop a utility rate study to forecast
annual operating and capital financial obligations over a multi-year period and recommendations for
tipping fee adjustments to fully fund these obligations.
An initial kickoff meeting will be scheduled to introduce the project team, review the scope of work,
identify project objectives, outline the project schedule and key milestone review points, and discuss
appropriate lines of communication. Attendees will also review a list of data items needed to begin
the solid waste cost -of -service rate study.
Parametrix will develop a rate and financial toolkit. The rate and financial toolkit provides the
analytical framework for the rate study. The toolkit is a fully integrated financial management model
that establishes a cause -and -effect relationship between solid waste activities (e.g., tons,
transactions, loads) and County revenues, costs, and rates.
Parametrix will perform solid waste data validation and forecasting. Once the conceptual design of the
toolkit is finalized, Parametrix will review and validate solid waste operational data for use in the rate
study. These data are the basis for developing key components for the revenue requirement and cost -
of -service analyses. Data validation makes sure that tonnage, transaction, and load data are
reconciled for accuracy and consistency within the rate study.
Parametrix will determine revenue requirements. A revenue requirement analysis determines the
total amount of money that the County must collect from tipping fees to pay for all operating and
capital expenditures as well as the financial requirements to comply with the County's fiscal policies.
The revenue requirement is net of other miscellaneous charges from grants and interfund transfers.
Parametrix will perform a cost -of -service analysis. The cost -of -service analysis provides a defensible
basis for allocating the revenue requirement to each customer class of service based on their unique
service characteristics and requirements. In some cases, County expenses can be directly assigned
to a particular customer class. In other cases, costs may not directly relate to a single customer class
and, as a result, are treated as a shared cost. Landfill disposal costs would likely be allocated
proportionally to all customer classes that deliver solid waste to County facilities.
Parametrix will develop a rate design for changes to the system of charges for customers of the solid
waste system. At a basic level, the rate design process establishes cost -based, equitable rates for
each customer class, which generate the overall revenue needs to fully support the operations.

Task 7 - Pavement Design for Entrance Improvements
Task Leader - Drew Norton, PE
The New Landfill entrance in the vicinity of the scale facility has been experiencing roadway
deterioration. The County plans to complete this work with its own crews but would like a pavement
section design recommendation.
Approach
Parametrix will evaluate current conditions and provide recommendations for subgrade
improvement, and base/top course and pavement type and thickness. The results of the evaluation
will be a brief technical memorandum with a pavement section figure. Materials will be identified per
the Washington State Department of Transportation 2024 Standard Specifications for Road, Bridge,
and Municipal Construction. The resulting technical memorandum will be for the County's
consideration in self -performing the repaving of the entrance road and will not be appropriate for
bidding or other third -party use.
