Dear Mr. Hill:
While preparing the NC Solid Waste Management Annual Report for FY 2018-2019, the Solid
Waste Section (SWS) notices that Alamance County C&DLF, Permit No. 0104-CDLF-1993did not received any permitted C&D wastes in the FY 2018-2019. The recent Facility
Compliance Inspection Report confirmed that this C&DLF unit has been inactive sinceSeptember 18, 2017. According to the SWS records and the permit (DIN 25364) dated
December 10, 2015, the County operated the C&DLF unit – Phases 1 and 2 whichencompasses 6.32-acre waste footprint.
After receiving this e-mail notification, Alamance County (the County) shall immediatelyplace intermediate cover over the inactive landfill area where shall be stabilized with
vegetative ground cover or other stabilizing material according to Rule 15A NCAC 13B.0542(f)(2). Upon completing installation of the intermediate cover, the County should inform
the SWS in writing and the written notation shall be placed in the facility operating record.
According to data stated in December 17, 2018 e-mail message, the C&DLF unit – Phases 1and 2 has in-placed waste volume of 372,500 cubic yards (CY), which exceeded the permitted
gross capacity of 219,731 CY for the Phases 1 & 2 (DIN 25364). The approved facility plan(DIN 25366) of this landfill unit stated the landfill unit has an approved gross capacity of
415,000 CY. Based on the above-referenced data, the remaining capacity (waste plus thelandfill cover system) of the landfill is approximately 38,000 CY.
Because the Alamance County C&DLF unit has remaining capacity of 380,000 CY and ceased
waste disposal activities more than a year, pursuant to Rule 15A NCAC 13B .0543(c)(5)(C),the SWS determines that Alamance County shall begin closing the C&DLF unit according to
Rule 15A NCAC 13B .0543(c)(5) and the approved closure plan (DIN 25366) within 30calendar days (No later than December 12, 2019) after receiving this notification.
Pursuant to Rule 15A NCAC 13B .0543, the County may request the SWS an approval of an
extension of the closure activity by submitting a written request, which, in a minimum, shouldinclude the acceptable causes for postponing the rule-required closure activities, the new
closure schedule, and the detailed continuous efforts to be made for preventing threats tohuman health and the environment from the unclosed C&DLF unit.
Please contact me if you have any question of this closure request.
Regards,

From: Chao, Ming-tai

Hi Wayne: According to your calculation and updated info in the e-mail message, the constructed andoperational volume for Phases 1 & 2 of the C&DLF unit are: Constructed volume (air space + cap) = 410,500 CYVolume used (in-place waste volume as of the date submitting 2017-2018 Annual Rpt) =372,500 CY I would think the data is acceptable for this year annual report. No overfills the landfill unit atthis time. BUT, I believe there is a bigger problem, or I should say the Facility Plan must be overhauledin the near future. The approved gross capacity (air space + period cover + final cap) for this C&DLF unit =415,000 CY (This amount was approved by a local government approval processes[DIN25366]) The constructed volume/interim capacity (Phase 1+2) = 410,500 CYThe remaining gross capacity for this C&DLF unit = 415,000 CY - 410,500 CY = 4,500 CY This 4,500 CY is the only capacity left for the future development (either lateral or verticaldevelopments) for this C&DLF unit. But it is likely no Phases 3, 4, & 5 as described in 2015Facility Plan any more. Of course, the County can go through another local governmentapproval processes (substantial amendment to the permit per NCGS 130A-294(b1)) forincreasing more capacity than the current approved one (415,000 CY). This permit action willconsidered as a new permit per NCGS 130A-294(a3)(1); therefore a permit fee is required perNCGS 130A-295.8. By the way, the PTC for Phase 3 of the C&DLF unit (DIN 25364) has expired on June 16,
2017. The issuance of PTO for Phase 3 is an administrative error; therefore, the Solid WasteSection revokes the PTO for Phase 3 of the C&DLF unit (DIN 25364).
Please contact myself if you have any question on this matter. By the way, I will be on
vacation for the rest of this year from 12/21/18, if I don’t hear from you this week, I wouldlike to wish you and your family have a Merry Christmas and Happy and Prosperous New
Year in 2019.

Ming,

Per our discussion last week, we calculated the available air space for Phases 1 and 2 of the CDLF. 
We used the subgrade drawing provided in the initial permit produced by Hazen-Sawyer with the
above grade as-built topography determined by the last annual survey. Our volume used is 372,500
cubic yards with approximately 3,000 cubic yards remaining on top.  The cap will require
approximately 35,000 cubic yards.  Therefore, the total volume of Phases 1 and 2 is 410,500 cubic
yards including the capping material.

Phase 3 has yet to be developed and may never be developed.  The available volume for it remains
66,859 cubic yards without capping material.

I hope this will satisfy any discrepancies and if you need additional info or have questions, please let
me know.

Hope you have a nice two week holiday vacation.

Thanks and have a nice day.
