Biosolids Dewatering Facility
Phase 1 — Site Work & Foundations Package
Rockingham County
Dear Mr. Corcoran:
A letter of request for Authorization to Construct was received August 5, 2008, by the
Division, and final plans and specifications for the subject project have been reviewed and found
to be satisfactory. Authorization is hereby granted for the Phase 1 (Site Work and Foundation
Package) construction of the Biosolids Dewatering Facility at the existing 13.5 MGD
Wastewater Treatment Plant, with discharge of treated wastewater into the Dan River in the
Roanoke Basin. With the completion of Phase 1 and the future Phase 2 Biosolids Dewatering
Facility construction projects, the Biosolids Dewatering Facility will be operational.
This authorization results in no increase in design or permitted capacity and is awarded
for the construction of the following:
Concrete foundations for the (approximately) 28-foot by 46-foot dewatering
building, the 80-foot by 185-foot sludge storage shelter, and the 50,000 gallon
sludge storage tank, and associated site work and yard piping, in conformity with
the project plans, specifications, and other supporting data subsequently filed and
approved by the Department of Environment and Natural Resources.
The issuance of this Phase 1 Authorization to Construct (ATC) for the Site Work &
Foundation Package of the Mebane Bridge Road WWTP Biosolids Dewatering Facility in no
way implies that issuance of the authorization for the Phase 2 construction of this facility will be
granted. The Phase 2 ATC for the Biosolids Dewatering Facility may be issued after a complete
review of the plans and specifications for this portion of this project. Construction of facilities
other than those approved in this ATC shall not take place until the Phase 2 ATC is issued.
This Authorization to Construct is issued in accordance with Part III, Paragraph A of
NPDES Permit No. NCO025071 issued August 9, 2002, and shall be subject to revocation unless
