Subject: NPDES Permit NC 0024252 Renewal
NCDEQ/DWR/NPDES
To whom it may concern;
The City of Conover respectfully request a renewal of Permit NC0024252 for the Northeast Wastewater
Treatment Plant(NE WWTP).
The NE WWTP,which was put on line in 1991, consists of a mechanical bar screen and an aerated grit
removal system dumping onto a central conveyor. The wastewater is pumped by lift station to four(4)
continuous flow sequential batch reactors. Each reactor has a 0.375 mgd capacity for a total design flow
of 1.5 mgd. From the reactors the wastewater is decanted and flows to five (5) shallow bed rapid sand
filters for tertiary treatment. After tertiary treatment the wastewater is disinfected with sodium
hypochlorite and then dechlorinated with sodium bisulfite. After dichlorination, a post aeration basin
increases the dissolved oxygen and the effluent is then discharged to Lyle Creek. The effluent is
discharge in batches and thus is not a continuous flow except in some storm situations.
Waste Activated Sludge is held in a 75,000-gallon aerated holding tank and thickened on a two-meter
gravity belt thickener to about 4 % solids. The thickened sludge is stored in a 35,000-gallon aerated tank.
The thickened sludge is then loaded into a 6,000-gallon tanker and transported to our Reginal Compost
Facility.
The city of Conover generates about 180 dry tons of residuals per year. Conover participates in a
Regional Compost Facility(Permit number WQ004563) with the City of Hickory. The facility is
designed to treat 20 dry tons per day and the City of Conover owns 15% of the capacity for a total of 3
dry tons per day.
Enclosed is EPA for 2A(tables a,b, c, and d), a diagram showing the NE WWTP treatment process, a
topographical map of the NE WWTP area, copies of Chronic Toxicity test and copies of a second species
toxicity test.
