VAN DER VAART Secretary MICHAEL SCOTT Director September 22, 2016 Sent Via Email – sam.lockridge@clevelandcounty.com Mr. Sam Lockridge, Coordinator of Health Services Cleveland County 315 East Grover Street Shelby, North Carolina 28150 Re: Design Hydrogeologic Approval Cleveland County Landfill Self-McNeilly Phase 3 Expansion Permit No. 2301-MSWLF-2009 DIN 26700 Dear Mr. Lockridge, The Solid Waste Section (Section) has completed a technical review of the Design Hydrogeologic Report (DIN 26208) submitted on your behalf by Municipal Engineering on June 8, 2016 for the Phase 3 expansion at the Cleveland County Self-McNeilly MSW Landfill. The Water Quality Monitoring Plan (DIN 26209) and the Landfill Gas Monitoring Plan (DIN 26210) were also reviewed. The Phase 3 expansion is approximately 16.38 acres. The Water Quality Monitoring Plan associated with Phase 3 is amended to include four (4) groundwater monitoring wells, MW-109, MW-110S/MW-110D and MW-111, which will be converted from piezometers. There are no new proposed surface water monitoring locations. This monitoring plan is in addition to the previously approved June 2014 Water Quality Monitoring Plan (DIN 21283). The water quality monitoring network shall be sampled semi- annually. The Landfill Gas Monitoring Plan associated with Phases 1-3 is amended to include six (6) onsite structures (GARAGE_1, GARAGE_2, BREAK_RM, RANGEOFC, CONCESSN and SCALE_HS). No landfill gas monitoring wells are proposed due to the site being surrounded by surface water bodies. This plan supersedes the June 2014 Landfill Gas Monitoring Plan (DIN 21282) The landfill gas monitoring network shall be sampled quarterly. The Design Hydrogeologic Report, the Water Quality Monitoring Plan and the Landfill Gas Monitoring Plan meet the criteria required in 15A NCAC 13B .1623(b), .1624(b)(4) and .1626(4) and therefore, this portion of the Permit to Construct application is approved. An electronic PTC Application – Design Hydro Approval Cleveland Co Self McNeilly – Phase 3 2301-MSWLF-2009 DIN 26700 September 22, 2016 Page 2 of 3 copy of the approved Design Hydrogeologic Report (DIN 26208), the Water Quality Monitoring Plan (DIN 26209) and Landfill Gas Monitoring Plan (DIN 26210) can be obtained on the Solid Waste Section’s website: http://deq.nc.gov/about/divisions/waste-management/solid-waste- section, click on “Documents”. Any existing monitoring wells, piezometers or boring within the proposed footprint of the Phase 3 expansion area will need to be properly abandoned prior to construction activities commencing at Phase 3. Piezometers, groundwater monitoring wells, and borings, located in proposed Phase 4 may be abandoned now or after a Permit to Construct is issued by the Solid Waste Section. Please adhere to the following conditions: Prior to construction of cell(s), all piezometers, ground-water monitoring wells, and borings, located in the proposed cell(s), shall be properly abandoned by overdrilling first (exception of non-cased borings) and sealed with grout in accordance with 15A NCAC 2C .0113, entitled “Abandonment of Wells”. a. In areas where soil is to be undercut, abandoned piezometers, monitoring wells, and borings must not be grouted to pre-grade land surface, but to the proposed base grade surface to prevent having to cut excess grout and potentially damaging the wells. b. Well abandonment records (GW-30 form) for each decommissioned piezometer, boring, and groundwater monitoring well must be certified by a Licensed Geologist in accordance with rule .1623(b)(2)(1) and submitted to the Solid Waste Section in accordance with 15A NCAC 02C.0114(b). New groundwater monitoring wells (MW-109, MW-110S/110D, MW-111) associated the Phase 3 expansion must be sampled for the Appendix I constituent list prior to the Section issuing the Permit to Operate. The groundwater and surface water monitoring data collected at the landfill facility shall be submitted to the Section in electronic (pdf) format. Guidelines for sampling groundwater and surface water, and submitting data electronically can be located at the Section’s web site. http://portal.ncdenr.org/web/wm/sw/envmonitoring PTC Application – Design Hydro Approval Cleveland Co Self McNeilly – Phase 3 2301-MSWLF-2009 DIN 26700 September 22, 2016 Page 3 of 3 Additional Geologic, Ground Water and Monitoring Requirements will be included in the Permit to Construct.
