VAN DER VAART Secretary MICHAEL SCOTT Director November 3, 2016 Sent Via Email – rvail@santekenviro.com Mr. Ron Vail Vice President of Engineering 650 25th Street, N.W., Suite 100 Cleveland, Tennessee 37311 Re: Design Hydrogeologic Approval White Oak Subtitle D Landfill Phases 4 and 5 Expansion Haywood County 4407-MSWLF-1993 DIN 26977 Dear Mr. Vail, The Division of Waste Management, Solid Waste Section (Section) has completed a technical review of the Design Hydrogeologic Report submitted on your behalf by Bunnell-Lammons Engineering, Inc. on September 28, 2016 for the expansion of Phases 4 and 5 at the White Oak Subtitle D Landfill in Haywood County. The Water Quality Monitoring Plan and the Landfill Gas Monitoring Plan for Phases 1-5 were also reviewed. The expansion area of Phases 4 and 5 is approximately 14.3 acres. The Water Quality Monitoring Plan is amended to include five (5) groundwater monitoring wells (MW-18, MW-19, MW-20, MW-21 and MW-22) and one (1) surface water sampling location (SW-8) associated with Phases 4 and 5. The current monitoring network is composed of thirteen (13) groundwater monitoring wells (MW-1A, MW-2/2D, MW-3r/3Dr, MW-4A, MW- 8, MW-11S/11D, MW-14, MW-15, MW-16 and MW-17) and six (6) surface water sampling locations (SW-1, SW-2, SW-3, SW-5, SW-6 and SW-7). The updated Water Quality Monitoring Plan for Phases 1-5 includes eighteen (18) groundwater monitoring wells, seven (7) surface water sampling locations and one leachate sampling location. The water quality monitoring network shall be sampled semi-annually. The Landfill Gas Monitoring Plan proposes no new landfill gas monitoring wells associated with Phases 4 and 5. The existing monitoring network consists of seven (7) monitoring wells (LFG-1, LFG-2, LFG-4R, LFG-7, LFG-8, LFG-9 and LFG-10) and two (2) on site structures, the scale house and maintenance building. The landfill gas monitoring network shall be sampled quarterly. PTC Application – Design Hydro Approval White Oak MSW – Phases 4 and 5 4407-MSWLF-1993 DIN 26977 November 3, 2016 Page 2 of 3 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 copy of the approved Design Hydrogeologic Report (DIN 26875), the Water Quality Monitoring Plan (DIN 26742) and Landfill Gas Monitoring Plan (DIN 26973) can be obtained at the following link: http://edocs.deq.nc.gov/WasteManagement/Search.aspx Any existing monitoring wells, piezometers or boring within the proposed footprint of the Phases 4 and 5 expansion area will need to be properly abandoned prior to construction activities commencing. Piezometers, groundwater monitoring wells, and borings, located in the proposed Phases 4 and 5 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). The new groundwater monitoring wells (MW-18, MW-19, MW-20, MW-21 and MW-22) associated the expansion of Phases 4 and 5 must be sampled for the Appendix I constituent list prior to the Section issuing the Permit to Operate. The groundwater, surface water monitoring and leachate 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 on the Section’s website: http://deq.nc.gov/about/divisions/waste-management/waste-management-permit- guidance/solid-waste-section/environmental-monitoring PTC Application – Design Hydro Approval White Oak MSW – Phases 4 and 5 4407-MSWLF-1993 DIN 26977 November 3, 2016 Page 3 of 3 Additional Geologic, Ground Water and Monitoring Requirements will be included in the Permit to Construct.
