(BLE) is pleased to submit this work plan to the North Carolina Division of Waste Management (NCDWM) Solid Waste Section (SWS) for the Phase 2 construction and demolition (C&D) landfill expansion area on behalf of Rutherford County, Odom Engineering, PLLC (Odom), and McGill Associates (McGill). The work plan addresses the groundwater assessment activities required by the SWS in support of the permit application (in progress) for the Phase 2 C&D landfill expansion. PROJECT INFORMATION The project information below was obtained from multiple in -person and telephone meetings and emails between BLE, McGill, Odom, Rutherford County, and the SWS. The subject landfill site is located in Rutherford County, North Carolina, between the cities of Rutherfordton and Spindale with a physical address of 656 Laurel Hill Dr, Rutherfordton, North Carolina. Rutherford County owns and operates a closed Subtitle D municipal solid waste (MSW) landfill and an active C&D landfill consisting of one waste unit designated Phase 1. The county plans to expand the C&D landfill in an area designated Phase 2 which is approximately 17 acres and construct one new approximate 5.5-acre C&D waste unit in the expansion area. Rutherford County has retained McGill as design and permitting engineer for the project. Rutherford County has also retained BLE (as a subconsultant to McGill) to provide design hydrogeologic services, geotechnical engineering, monitoring plan services, and construction quality control services for the project. Work on the project has begun. McGill has defined the limits of the expansion area and developed a conceptual design plan. BLE has performed six (6) borings and installed five (5) piezometers in the expansion area as part of the design hydrogeologic report (DHR). I 6004 Ponders Court. Greenville, SC 29615 t�864.28B.1265 AB64,288.4430 -info@hlemrpxom sLECORP.COM 1s 1m 1i Work Plan for Groundwater Assessment -- Phase 2 Expansion Area January 16, 2020 Rutherford County Landfill, North Carolina BLE Proposal Number J20-13675-04 Several discussions with the SWS occurred after the DHR work started. The SWS expressed concern about development of a new waste unit in the expansion area due to an ongoing assessment of corrective measures (performed by others) for the existing C&D and MSW waste units. As a result, the SWS informed Rutherford County, McGill, and BLE that they will require a background assessment of the groundwater quality in the expansion area as a condition of the permitting process for Phase 2. Rutherford County, Odom, and McGill requested that BLE prepare this work plan to perform the required sampling, analysis, data evaluation, and reporting for the background assessment. WORK PLAN SCOPE OF SERVICES The objective of this project is to collect and report the groundwater quality information required by the SWS in support of the permitting process. Work Plan Contents Table 1— Groundwater Elevations and Well Data — This table includes all wells (piezometers, groundwater monitoring wells, and landfill gas monitoring wells) in the facility records. Please note that several of these wells may not currently exist; they may have been abandoned. The table includes well construction information and the hydrogeology monitored by each well. Wells selected for sampling as part of this plan have been highlighted in yellow. Water level data collected by Scarlett Geophysical (October 2019) and BLE (November 2019) are presented on the table. Please note that piezometers installed by BLE in the Phase 2 expansion area were not present in October 2019. • Table 2 -Background Sampling Matrix —Water Quality and Table 3 —Metals List -Background Sampling — These tables include the laboratory and field parameters selected for analysis as part of the work plan. The matrix includes those parameters currently utilized for monitoring of the C&D waste unit plus dissolved metals. • Figure 1- Composite Groundwater Elevation Contour Map (October & November 2019) — This map shows the proposed limits of the Phase 2 C&D expansion area outlined in red and also includes groundwater elevation contours for data from October and November 2019. The data indicates a west-southwest groundwater flow direction in the Phase 2 expansion area. Based on our preliminary review, these data appear to be similar to that in the historical facility records. Sampling, Analysis, and Reporting Plan BLE will provide the services of a geologist or environmental technician to conduct groundwater sampling of the eight (8) wells identified on the tables. Water levels will be collected prior to each sampling event. The wells will be purged and sampled within 24 hours of purging. We will attempt to purge three (3) well volumes. If a well appears to be low yield, less than three well volumes may be purged. Any well evacuated to dryness which does not recover within 24 hours will not be sampled. Efforts will be made to reduce sample turbidity during sampling to reduce the potential for false -positive metals results. Sampling logs will be prepared for each well sampled. Up to two (2) sampling events approximately 30 days apart are proposed as part of this work plan. 2 of 4 1s 1m 1i Work Plan for Groundwater Assessment -- Phase 2 Expansion Area Rutherford County Landfill, North Carolina January 16, 2020 BLE Proposal Number J20-13675-04 • BLE will submit the groundwater samples to a North Carolina certified laboratory for analysis via hand -delivery or overnight courier. The laboratory will perform the analyses indicted on the matrix. Please note that field parameters will be measured in the field by BLE during sampling and reported on the field sampling logs. • BLE will compile, review, and evaluate historical groundwater elevation data and prepare groundwater elevation contour maps (as the historical site data allows) to illustrate groundwater flow direction at the site. A groundwater elevation contour map from each sampling event will be included in each report. Supplemental historical maps may be included if necessary. • BLE will prepare written reports for up to two (2) sampling events which will include a description of field activities, sampling logs, summary tables, maps, laboratory data, and our conclusions and recommendations. The reports will be submitted to the SWS for review. SCHEDULE Based on our discussions with the SWS, the following completion schedule is anticipated: SWS Review of Work Plan 1 week First Sampling Event (last week of January 2020) 2 days Laboratory Analysis (Event 1) 2 weeks Preparation of Report of First Event 1 week Second Sampling Event (last week of February 2020) 2 days Laboratory Analysis (Event 2) 2 weeks Preparation of Report of Second Event 1 week SWS Review of Reports 2 weeks APPROXIMATE DURATION 13 weeks The anticipated project duration can be completed as shown above assuming that the project does not have delays due to inclement weather, site access, lab data acquisition, or other delays beyond our control. This schedule does not include review time by McGill, Odom, or Rutherford County. ASSUMPTIONS We have assumed that any well identified in an approved sampling matrix will yield sufficient groundwater for sampling. We have assumed that up to two sampling events will be required. We have assumed that we may change the sampling plan based on the results of the first sampling event. 3 of 4 1s 1m 1i Work Plan for Groundwater Assessment -- Phase 2 Expansion Area Rutherford County Landfill, North Carolina CLOSING January 16, 2020 BLE Proposal Number J20-13675-04 We appreciate the continued opportunity to work with the SWS to address regulatory issues and to develop solutions for permitting.
