Dear Melissa:
Subject: 2018 Financial Assurance for Closure and Post -Closure Care and
Corrective Action
Chambers Development MSW Management Facility
Permit No. 04-03
CEC Project 165-276
Civil & Environmental Consultants, Inc. on behalf of Chambers Development of North Carolina,
Inc. is submitting the attached detailed written estimate, in current dollars, of the cost of hiring a
third party to close the largest area of the MSWLF unit at any time during the active life in
accordance with the closure plan required under Rule .1629. The estimate is Attachment 1.
The attached estimate includes 14.86 acres of additional landfill area from the recently
constructed Phase 3, Cell 1. The closure and post -closure care cost unit prices were calculated
by inflating the 2017 unit prices by 1.8% to account for inflation in accordance with the NCDEQ
inflation factor of 1.018 effective January 1, 2018.
Estimated Total Closure and Post -Closure Care Costs (For 30 year period) is $11,363,000.
The 2018 Estimate for Corrective Action was calculated by applying the NCDEQ inflation factor
of 1.018 to the 2017 Estimate of Corrective Action Cost.
Estimated Cost for Corrective Action is $2,145,586.
Please let me know if you have any questions or comments. I can be reached at [phone].
