From 1976 to 1997, the Oxford Municipal Solid Waste Landfill (MSWLF) – Unit 1 operated on this property as a permitted MSWLF under Permit No. 39-01, with an initial disposal area of 21.9 acres. The landfill was not constructed with a liner below the waste. The size of the closed MSWLF disposal area – Unit 1 is 28.8 acres. The volume of the closed MSWLF- Unit 1 is approximately 690,261 tons or 1,380,522 cubic yards. 2. In 1997, the transition plan for the MSWLF – Unit 1 included a permit modification request to construct and operate a Construction and Demolition Debris Landfill (C&DLF) on top of the closed MSWLF – Unit 1. On January 1, 1998, the C&DLF on top of the closed MSWLF – Unit 1 began receiving waste. Initially, the total landfill property consisted of 24 acres, but additional property was added over the years to bring the total landfill property to its current size of 397.73 acres. 3. In June 2008, to comply with the North Carolina Solid Waste Management Rule (Rule)15A NCAC 13B .0547(4), Granville County requested an approval for continued operations of the C&DLF according to the new facility plan and had a final fill elevation up to 606 feet above mean sea level (amsl). 4. In May 2012, the new Facility Plan was approved to incrementally develop the new Subtitle D MSWLF, containing three units – Unit 2, Unit 3, & Unit 4 under Permit No. 3901- MSWLF-2012 on the east side of the closed unlined MSWLF – Unit 1. The new MSWLF will be constructed with liners and leachate collection systems in accordance with Rules 15A NCAC 13B .1600 et seq. and will encompass approximately 157.8-acre waste footprint. The Unit Permit No.:3901-CDLF-1997 Oxford C&D Landfill Permit to Operate December 1, 2014 DIN 22365 Page 3 of 21 2 – Phase 1 encompassing 11-acre waste footprint was constructed in 2012 and receiving wastes for disposal in 2013.
