Task 2 -Groundwater Compliance Monitoring (2021)
Task Leader: Glen Wallace (PGG)
Background:
Grant County (County) is required under WAC 173-351 to collect groundwater samples quarterly from
solid waste monitoring wells surrounding the Old Landfill and New Landfill as outlined in the August
2019 Environmental Monitoring Plan.
Exhibit A: Amendment 24 555-3746-001X06
FY 2021 Ephrata Landfill Eng. and Env. Services 2 September 2021
Ephrata Landfill
The County is also required to submit quarterly and annual groundwater monitoring reports to Ecology
and Grant County Health District (GCHD). Pacific Groundwater Group (PGG), as a subcontractor to
Parametrix, is currently contracted to assist the County in collection of samples and associated reporting
through the second quarter 2021. For this contract amendment,. PGG will assist the County in collection
of samples through fourth quarter 2021 (third quarter 2021 and fourth quarter 2021) and produce one
quarterly report. The fourth quarter results will be captured in the 2021 annual report, which will be
performed under separate amendment in 2022. PGG and the County will each provide one person for
each sampling round. PGG will continue to manage the water quality database and generate reports.
PGG will also submit quarterly groundwater data results to Ecology's EIM database as required by WAC
173-351.
Solid waste landfill groundwater sampling work for the Old and New Landfills occurs at the same time
and the reports are combined; however, work on the Old and New Landfills will be separated on
invoices based on a standardized percentage of effort.
Approach:
Task 2.1- Maintain Database for through 2021
PGG will work directly with Analytical Resources Inc. of Seattle to receive groundwater monitoring data
in standardized electronic digital format. Data will be reviewed for quality and entered into PGG's
groundwater monitoring database for the Ephrata Landfill. This budget also includes loading
monitoring data into Ecology's EIM database. Data will be entered for all wells sampled in the third
quarter sampling event of the year 2021. The County will be provided a complete copy of the data
upon request.
Task 2.2 - Collect Groundwater Samples During Two Sampling Rounds
PGG will work with the County to collect groundwater samples during two sampling rounds (through
fourth quarter 2021). PGG will order bottles, and help County personnel operate the pumps, collect
samples, measure field parameters, measure water levels, and transfer samples. We anticipate that
each sampling round takes two long field days plus travel time. PGG will coordinate with the lab and
include lab invoices in project billings. The County will maintain pumps and other County -owned field
gea r.
Task 2.3 - Prepare and Submit One Quarterly Report
PGG will generate one quarterly report combined for both the Old and New Landfills, for the third
quarter 2021. The report will conform to requirements of WAC 173-351-415(2).
Task 2.4 - Prepare Data Summary for 2021 Annual Report
PGG will prepare data summary through fourth quarter 2021 based on available data through 2021. PGG
will prepare the 2021 Annual Report under the 2022 Engineering and Environmental Services
amendment. The 2021 Annual Report will be combined for both the Old and New Landfills. The report
will conform to requirements of WAC 173-351-415.
Task 2.5—Task Management
The task management task includes costs associated with PGG invoicing and personnel management
and communication.

Task 2.6 - Pump Replacement Support
As requested by the County, PGG will assist in replacing or coordinating maintenance on groundwater
sampling pumps and appurtenances. This task will be specified upon request and may include elements
of pump removal, sourcing replacement equipment from vendors, and troubleshooting.
Deliverables:
PGG, under contract to Parametrix, will prepare and submit the third quarter 2021 groundwater monitoring
report, which will be forwarded to GCHD and Ecology.
Task 3 - Landfill Gas Operations, Monitoring, and Reporting
Task Leader: Drew Norton, EIT
Approach:
Task 3.1— Landfill Gas Monitoring and System Operational Support
Parametrix will monitor the landfill gas collection system, including flare facility, and gas probes during
two rounds on a quarterly basis (September and December 2021). Parametrix will generate one annual
letter report (2021) combined for both the Old and New Landfills' landfill gas collection systems and gas
probes, in accordance with the NOC APPROVAL ORDER NO. 19AQ-E051, as well as summarize past
landfill gas probe monitoring conducted by Parametrix.
Parametrix will assist County staff in operating and maintaining the active landfill gas system, following
the guidance provided in the Active Landfill Gas Operations and Maintenance Manual. Parametrix will
provide guidance to safely and effectively operate the Ephrata Landfill gas collection system that will
help control landfill gas from migrating around the Old Landfill and emitting from the New Landfill.
The system operations monitoring will include and be based upon the following:
• Changes in landfill gas constituent concentrations and flow rates over monthly time interval.
• Operations and maintenance of the landfill gas system.
• Perform routine inspections and maintenance of the gas system.
• Monitor each individual trench/well wellhead for pressure, methane, oxygen, carbon
dioxide, temperature, and flow.
• Adjust each individual wellhead flow to reach stable operation and/or generation flows.
The manual will be used as a reference and training guide to operate and maintain the gas collection
system. We will assist the County in the proper operation and data collection required to satisfy the
greenhouse gas regulations.
We estimate that each landfill gas monitoring round takes one field day plus travel time and reporting.
The County will supply the landfill gas meter (Landtech Gem500) to monitor for methane, oxygen,
carbon dioxide, and pressure.
Exhibit A: Amendment 24
FY 2021 Ephrata Landfill Eng. and Env. Services
Ephrata Landfill
555-3746-001 � 06
September 2021
We anticipate that the landfill gas system will have reached stable operation by the start of this work.
Landfill gas system stability will be evaluated based on the following:
• Changes in landfill gas constituent concentrations and flow rates over monthly time interval.
• Changes in landfill gas temperature at individual collection points (e.g. wellheads).
• Changes in overall volumetric flow and flows from individual collection points.
Landfill gas system operational stability will be characterized by little change in the above parameters
over significant time intervals (e.g. month) or steady, predictable data trends.
Task 3.2 —Title V Air Quality Operating Permit Semi -Annual and Annual Reporting
a. Assistance on any deviations through the year.
b. Prepare permit condition forms using Ecology Air Quality templates that communicate
activities during the year.
c. Train County staff on proper permit condition reporting and compliance that anticipates one
site visit.
d. Prepare landfill gas system overall site plan update in accordance with Title V Operating
Permit.
e. Prepare draft content for the 2021 annual report in accordance with the Operating Permit
conditions. Submit electronic copies to County for review.
f. Final 2021 annual reporting will be completed and submitted to the County for delivery to
Ecology Air Quality Program via email at Emissions.inventory@ecy.wa.gov by January 31,
under the 2022 Engineering and Environmental Services amendment.
The Title V Operation Permit (being prepared) will include 2021 as the first reporting year, with the first
annual report due on January 31, 2022. We will prepare the final 2021 Annual Report under the 2022
Engineering and Environmental Services amendment.
Deliverables:
Parametrix will prepare and submit a summary of landfill gas collection system and probe monitoring data,
which will be forwarded to GCHD and Ecology.
Landfill Title V Permit Annual Reporting —Annual Report data summary information for communicating Title
V Operating Permit activities, deviations, and compliance reporting.
