Subject: Request for Authorization to Construct
Onslow Water and Sewer Authority, Dixon WTP, Replacement lagoon liner
NPDES Permit No. NC0083551
Plans and specification and supporting documents were received in the
Wilmington Regional office for review. The work that will be conducted will not disturb
any areas outside of the area specified in the plans. The plans propose a replacement of
the synthetic liner with an impervious geomembrane liner to meet the specifications
outlined in Part 2 of Section 02666 of the Bid Proposal and Contract Document (project
RFB#2007-08-Lagoon 01).
The Dixon WTP utilizes three lagoons capable of holding 900,000 gallons of
wastewater each. All three lagoons are necessary for providing the adequate settling time
to meet the effluent limitations at the current rate of production of potable water.
Although still in use, the lagoon level has been lowered in anticipation of receiving the A
to C. The Wilmington Regional Office has no objections to the issuance of the
Authorization to Construct as requested in the plans and specifications provided. Thank
you for the opportunity to comment.
