AGENDA DATE: September 12, 2023
ACTION REQUESTED: Request Boards approval Resolution
BACKGROUND: Kittitas County Solid Waste operates the Ryegrass Facility
which includes multiple permits and activities.
The operations on site are governed under WAC 173.200,
WAC 173.350 and WAC 173.308 all of which require ongoing
environmental monitoring and permitting. This Amendment will
cover nine different areas onsite. Due to the complexity of the
site it is necessary to have the same consultant work with all of
the permits and regulations since some of the monitoring is
needed for multiple permits.
Task 1 will include siting and drilling a new ground water
monitoring well between the septage lagoons and the landfills.
The Department of Ecology Hydrogeologist has requested that
an up gradient well be installed per WAC 173.350-330, in order
to confirm background water quality. Over the years we have
talked with the DOE about this well and siting of it has been an
issue since we are on the top of the mountain and finding the
correct location. Prior Hydrogeologist had not required the
installation.
Task 2 Limited Purpose Landfill closure design services.
Task 3 Limited Purpose Landfill engineering services
Task 4 Evaluation of borrow soils to be used on site for cover
material. Testing of soil to be brought on to the site to be used
for cover material and to amend existing soils.
Task 5 Expansion of the Biolsolids land application area.
Task 6 SEPA Check list and Critical Areas Report update.
Task 7 Air permitting for the facility.
Task 8 Unanticipated, Critical Work Allowance.
Task 9 Annual Environmental Monitoring Reporting

SCOPE OF WORK
Kittitas County Solid Waste
Groundwater Monitoring Well, LPL Closure, Biosolids Expansion Area, and Air Permit
INTRODUCTION
Kittitas County Solid Waste Programs (County) owns and operates the Ryegrass Limited Purpose Landfill (LPL)
located in Kittitas County, Washington. The site is currently permitted under Washington Administrative Code
(WAC) 173-350-400, Limited Purpose Landfills. The current facility was reclassified as an LPL in 2004 with a
planned capacity of approximately 550,000 cubic yards.
Based on the results from the groundwater monitoring over the past several years, the Washington State
Department of Ecology (Ecology) has requested that a monitoring well work plan be developed and executed to
try to determine if the nitrates are entering the groundwater from the septage lagoons, a product of the closed
Municipal Solid Waste (MWS) landfill on site, the biosolids land application, or a different unanticipated factor not
related to activities on site. Once the source of the constituent is determined a plan can be developed on how to
address them in a way that will meet Ecology's directive.
The LPL is now nearing capacity and the County is planning a Final Closure of the LPL and beginning of Post -
Closure Care. Parametrix, Inc. (Parametrix) will assist the County in updating the Ryegrass LPL Closure Plan and
financial assurance documentation. Additionally, Parametrix will develop a plan for the conditioning of the soil
from another County project site to be used for Final Cover of the LPL.
County also owns and operates the Ryegrass Biosolids Management Facility that includes two 500,000-gallon
lined septage ponds installed in 2006, west of two leachate and process wastewater ponds and a biosolids land
application practice. The County is looking to add the area south of the existing LPL as a new biosolids application
area.
Parametrix will support the County in obtaining a modification to the existing General Permit for Biosolids
Management to increase the land application area for Class I and II septage. As part of this effort, Parametrix will
update the Site -Specific Land Application Plan (SSLAP) to include the new application areas, update the Plan of
Operation for the septage evaporation lagoons, and evaluate alternative crop types for more effective nutrient
uptake.
This scope is assumed to be executed over a two-year period with the timing of each item depending on outside
influences like regulations and facility capacity. Parametrix's services will be provided in accordance with the
following tasks.
PROJECT MANAGEMENT
Throughout the course of this contract, Parametrix will provide effective project management and coordination,
ensuring the scope of work is executed effectively within budget and schedule. The effort involved for Project
Management is included under each task. Parametrix will:

full cover depth has been applied. The County will analyze the survey and submit the information to the
regulators.
Services During Construction
• Responses to RFIs and Submittals
• Pre -construction meeting attended by engineer (on site)
• Final walk through by engineer
TASK 04 — EVALUATION OF BORROW SOILS FOR OTHER USES
Objective
We understand that Kittitas County Solid Waste is planning to close the Phase 1 area at its Ryegrass LPL and set
up a biosolids recycling facility on site. Closure of the Phase 1 area would consist of placement and compaction of
a soil cap comprised of two layers: 1) a low permeability barrier soil layer, and 2) an upper vegetative soil layer.
Concurrently, the County will be constructing a new transfer station, which will require extensive removal of
settlement prone soil. The intent of this geotechnical evaluation is to determine whether the soil removed from
the transfer station site will be suitable for use as final cover soil components at the Ryegrass LPL. In addition,
representative soil samples will be evaluated by a local agricultural laboratory (SoilTest of Moses Lake, WA) to
provide baseline parameters for soil fertility (for the vegetative cover soil layer) and for use in the biosolids
recycling process.
Activities
Herein, we present an abbreviated scope of the evaluation for HWA to perform:
• Conduct geotechnical testing on three bulk samples that HWA obtained at the Transfer station site
during foundation explorations conducted for the design of the new transfer station. The samples
represent soil composited from 3 areas where deep excavations will occur at the new transfer station
s ite.
• Geotechnical testing will include compaction (proctors), shear strength (direct shears) and remolded
permeability.
Kittitas County Solid Waste
Groundwater Monitoring Well, LPL Closure, Biosolids Expansion 5 September 2023
Area, and Air Permit
SCOPE OF WORK (continued)
• Agricultural testing will be conducted to determine soil fertility and compatibility with proposed final
cover vegetation, in addition to assessing the potential for soil use in the biosolids recycling process.
• The results of our geotechnical testing will inform our recommendations regarding, handling, drying,
placement, compaction, and stability of the soil used for final cover.
• Our findings and recommendations will be provided in a technical memorandum.
Parametrix shall assist in coordination and review of information for this task and assist where needed.
Deliverables
• Technical memorandum outlining the findings and recommendations for the soil.
TASK 05 — EXPANSION OF BIOSOLIDS LAND APPLICATION AREA
Objective
The objective of this task is to obtain a modification to the Kittitas County Ryegrass Septage Facility's (the Facility)
existing General Permit for Biosolids Management (Permit Number BT9208) to increase the land application area
for Class I and II septage.
Activities
The following activities will be performed to increase the land application area to include previously closed MSW
landfill areas and the footprint previously designated for expansion of the LPL.
• Coordinate with Ecology to apply for a permit modification to increase the land application area.
• Complete a SEPA checklist and threshold determination (to be completed under Task 09: SEPA Checklist).
• Prepare responses to public comments.
• Prepare a Site -Specific Land Application Plan (SSLAP) to include the new application areas.
• Update the Plan of Operation for the septage evaporation lagoons, which will include the additional two
leachate ponds as discussed in the next task.
• Evaluate alternative crop types for more effective nutrient uptake using region -specific sources (e.g.,
Washington State University Extension) and publications.
TASK 06 — SEPA CHECKLIST AND CRITICAL AREAS REPORT UPDATE
Prepare a SEPA checklist using the most recent version of the checklist form. The SEPA checklist that was
prepared for the Phase 2 LPL Expansion will be modified to reflect the LPL closure, new leachate lagoon and
biosolids land application.
Additionally, this task includes updating the Ryegrass Critical Areas Report and Habitat Management Plan
prepared for the previously proposed Phase 2 Expansion. The report will be modified to be non-specific to any
particular project on the site.

TASK 07 —AIR PERMITTING
Kittitas County Solid Waste Programs (County) owns and operates the Ryegrass Limited Purpose Landfill (LPL)
located in Kittitas County, Washington. Solid waste handling activities at the site are currently permitted under
Washington Administrative Code (WAC) 173-350-400, Limited Purpose Landfills.
Washington State air pollution control standards and requirements are covered under Chapters 173-400, -401,
and -460 WAC. Establishment of new equipment or modification of existing equipment that may cause an
increase in air pollution emissions is subject to minor new source review (NSR) under Chapters 173-400 and -460
WAC. Any facility that meets or exceeds the applicability requirements in WAC 173-401-300 is required to obtain
an air operating permit. Federal air pollution control standards for landfills are covered under the New Source
Performance Standards contained in Title 40 Code of Federal Regulations (CFR) 60 and the National Emission
Standards for Hazardous Air Pollutants contained in 40 CFR 63. All these air quality requirements are administered
by the Department of Ecology Air Program. Parametrix will evaluate applicability of the state and federal air
quality requirements to the Ryegrass LPL, determine actions necessary to achieve compliance with applicable air
quality requirements, and prepare required applications for submittal to Department of Ecology (Ecology).
This scope will be executed over a six-month period with the timing of each item depending on outside influences
such as regulatory review and availability of information from the County. Parametrix's services will be provided in
accordance with the following tasks.

Permitting Assistance
Objective
This task will utilize findings from the evaluation of applicable regulations to prepare and submit required
applications and provide follow-up with Ecology as required to obtain the corresponding approval(s).
Approach
The following activities will be performed as part of this task:
• Preparation of inventory of all regulated air pollutants from the operations at the site during calendar
year 2023. This will be done by using known emission factors and annual production throughput values to
be provided by the County, along with any proposed new equipment.
• Prepare the permit application submittal to Department of Ecology (Ecology) on behalf of the County. The
application will be based on the Ecology Instructions for Permit Application. Subtasks are expected to
include
o Review of equipment and process data
o Prepare best available control technologies (BACT) analysis
o Determine controlled potential to emit (PTE)
o Compare PTE of toxic air pollutants (TAPS) to WAC 173-460-150
o Prepare permit application
• Equipment usage and operations will be based on the 2023 LPL emissions inventory.
Deliverables
The following deliverables will be prepared:
• Draft NSR Permit application for County review and a final application for County signature by responsible
official(s) using Ecology application forms.

SCOPE OF WORK (continued)
Assumptions:
• The County will provide all data concerning equipment and materials throughput required for emission
inventory calculations. This data is necessary for the emission inventory calculations to be done.
• This scope does not include preparation of detailed ambient impact modeling utilizing AERMOD.
• Drawing and SEPA preparation will not be required.
TASK 08 — UNANTICIPATED, CRITICAL WORK ALLOWANCE
If unanticipated, critical work activity becomes necessary that is not within the authorized scope of services, the
County may authorize additional services utilizing the budget established in this task. An allowance of $10,000 has
been allocated to this task.
A"TASK 09 —ANNUAL ENVIRONMENTAL MONITORING REPORT
Objective:
Prepare annual report documenting the results of the four quarterly groundwater monitoring events in accordance
with the requirements of Solid Waste Handling Standards (Chapter 173-350 WAC), the current solid waste handling
permit issued by Kittitas County Health Department, the Sampling and Analysis Plan (SAP), and Guidance for
Groundwater Monitoring at Landfills and Other Facilities Regulated Under Chapters 173-304, 173-306, 173-350,
and 173-351 WAC (December 2012, Ecology Publication 12-07-072). Additionally, summarize the environmental
monitoring for gas and leachate monitoring of the LPL and the closed landfill.
Approach:
Prepare annual report summarizing the data collected during quarterly monitoring for the LPL and bi-annual
sampling for the closed landfill. The annual report will include evaluating the groundwater data in accordance with
the statistical approach presented in the SAP, which consists of establishing a subset of parameters for formal
detection monitoring and conducting quarterly comparisons of data to intrawell trends and those that are
statistically significant (95%) for both long term and short-term trends. For new wells without historical data, the
baseline data will be established with the initial eight data points.
Deliverables:
Draft (PDF via Parametrix SharePoint site) and Final Environmental Monitoring Annual Report (three copies and PDF
via Parametrix ftp site). The data for each quarter in 2024 will be submitted to the Ecology's EIM database following
submittal of the final annual report.
Assumptions:
• Copies of original laboratory reports, including laboratory QA/QC results, will be provided to Parametrix by
HWA or the analytical laboratory.
• Groundwater data will be provided to Parametrix in electronic format. The laboratory will provide
groundwater quality data in an EIM-ready format.
• Groundwater, leachate, and gas sampling will be completed by others (HWA)
• Gas and Leachate data will be provided to Parametrix by HWA with digital copies of the gas results and
electronic format of leachate testing.

SCOPE OF WORK (continued)
The annual report will summarize and interpret the following information (for all four quarters):
o All groundwater monitoring data, including laboratory and field data for the sampling periods
o Statistical results and/or any statistical trends, including findings of any statistical increases for the
year including time series plots of concentrations
o A summary of concentrations above the maximum contaminant levels of Chapter 173-200 WAC,
Water Quality Standards for Groundwaters of the State of Washington
o A summary of the leachate results compared to groundwater samples
o A summary of the landfill gas conditions
o Static water level readings for each monitoring well for each sampling event
o Potentiometric surface elevation maps depicting flow direction for each sampling event
o Groundwater flow velocity calculations for each sampling event and a discussion of any trends or
changes during the year
o Geochemical evaluation, including cation -anion balancing and trilinear and/or stiff diagraming for
each sampling event noting any changes or trends in water chemistry for each well during the year
One hard copy of the final report will be submitted to Kittitas County, Ecology, and the Health Department.
BUDGET
We estimate that the scope of services described herein will require a budget of $293,109.64. A breakdown of
these costs is presented on the attached spreadsheet. Parametrix agrees not to exceed the above budget without
the County's authorization. However, if during the work, a level of effort beyond the scope of our work appears
necessary, Parametrix will contact the County immediately to discuss any necessary modifications to the scope of
services and/or budget estimate.
The budget presented in this proposal reflects an estimate based on our current understanding of the project
requirements for a scope of work developed from information provided. Parametrix reserves the right to transfer
hours and budget dollars between tasks to satisfy project requirements. The budget also reflects estimated direct
costs to the project. Parametrix may also transfer funds allocated for direct costs to professional/technical hours,
or vice versa, to satisfy project requirements.
