The estimate is Attachment 1. The attached estimate includes 4.71 acres of additional landfill area from the recently constructed Phase 2, Cell 2C South. The closure and post-closure care cost unit prices were calculated by inflating the 2014 unit prices by 1.4% to account for inflation in accordance with the NCDENR inflation factor of 1.014 effective January 1, 2015. Estimated Total Closure and Post-Closure Care Costs (For 30 year period) is $7,783,000.
