Mr. Goodrich:Please
issue an "Authorization to Construct" for the following project:1.
Project Name: Contract No. 24 - Water Treatment Plant
Northwestern Wayne Sanitary District
2. Location: NCSR 1342 (Memorial Church Road)
Wayne County, NC
Description: Proposed discharge consists of iron filter backwash wastewater effluent
following treatment via a wastewater holding structure. The proposed
0.90 MGD water treatment plant will ultimately include three 10 ft.
diameter filters designed to remove approximately 1 mg/1 of iron from
the raw water supply prior to distribution as potable water to Sanitary
District customers. Each filter will typically be backwashed once per
day. A typical backwash cycle requires approximately 11,000 gallons of
potable water. Backwash wastewater will be discharged into a concrete
40' x 40' holding structure (67,000 gallon volume) to provide adequate
time for solids settling prior to discharge. Effluent from the holding
facility will be pumped via dual effluent pumps to the proposed discharge
point located on Great Swamp at NC Hwy. 581. The proposed
discharge point is located approximately 2,200 LF north of the
intersection of NCSR 1342 and NC Hwy. 581. Effluent characteristics
are anticipated to be within the limits specified in the NPDES Permit.
Please issue an Authorization to Construct for the proposed holding structure and effluent pumps.
Three copies of applicable plan sheets (Sheets G-4, G-5, G-24, G-25 from Contract No. 24 and Sheet
26 from Contract No. 21) illustrating the plant layout and proposed wastewater handling components
are included for your reference. A copy of NPDES Permit No. NC 0086959 is attached for your
reference.

I have reviewed the subject ATC's and have the same continents on each of them. They are all for settling
of the effluent from water treatment plant filter backwash. There should be a description of how the system
will work. How will the settled solids be separated from the effluent that will be pumped to the receiving
stream and what will become of the settled solids.
