Parametrik <br />Deliverables <br />Scope of Work <br />Draft and Final Environmental Monitoring Reports for the First, Second and Third Quarters of 2024. <br />The quarterly data will be submitted to Ecology's EIM database. <br />Draft and Final Environmental Monitoring Annual Report for 2024. The final report will be submitted <br />by April 1, 2025. The data for Fourth Quarter 2024 will be submitted to Ecology's EIM database <br />following submittal of the final annual report. <br />The Environmental Monitoring Reports will include: <br />• Laboratory reports and field data sheets <br />• A data validation summary report <br />• Tabulated groundwater results <br />• Time -series plots <br />• Static water level measurements and potentiometric surface maps <br />• Groundwater flow velocity calculations <br />• A summary of statistical comparisons in accordance with the Draft SAP <br />• Geochemical evaluation, including cation -anion balancing and trilinear and/or stiff <br />diagraming noting any changes or trends in water chemistry for each well <br />• LFG Monitoring Sheets <br />• Tabulated LFG monitoring data suitable for quarterly reporting <br />A draft and final summary letter report detailing the Balefill gas vent modifications <br />Objective <br />Based upon initial review of the LPL as part of the NOC application with Department of Ecology, a <br />Tier 2 analysis of landfill gas generation from the LPL will be required. This results from <br />Toxic/Hazardous Air Pollutants (TAPs/HAPs) being above the Small Quantity Emissions Rate (SQER) <br />and Acceptable Source Impact Level (ASIL), per the LandGEM modeling. It is believed that the <br />speciation and generation rate calculated by the LandGEM modeling is overestimating these values <br />and thus not representative of the actual gas generation by the LPL. This work is being included to <br />provide Tier 2 analysis of the LPL and will generate a site -specific characterization of the landfill gas <br />generation from the LPL that will be utilized to modify the NOC application (Task 07). <br />Kittitas County Solid Waste 553-1763-010 <br />Ryegrass LPL and Future Uses 6 June 2024 <br />Amendment 02 <br />
