This is a request to renew NPDES Permit NCO074012 issued to
Lincoln County for Middle Forney Creek WWTP in the East Lincoln
County Water & Sewer District. This permit expires July 31, 2001.

Sludge Management Plan
Prior to February 2000 our sludge was transported by pumper
trucks to the City of Lincolnton WWTP and applied to their drying
beds. Beginning in February 2000 Lincoln County contracted with
Southern Soil Builders of Roaring River, N. C. to land apply our
sludge. After a sludge analysis is performed and the sludge is
checked for a reduction in total volatile solids the sludge is pumped
from our sludge holding tank to Southern Soil Builder's tanker trucks,
which then transport the sludge to the appropriate field. There the
sludge is applied to the soil by Southern Soil Builder's equipment and
personnel.

Middle Forney Creek W WTP is a .75 MGD wastewater facility consisting of an influent pump
station with dual pumps, a Parshall flume with ultrasonic flow measuring and recording, a mechanical bar
screen with a manual bypass screen, an aerated grit removal basin measuring 10 ft. X 10.5 ft. X 10 ft.
with a capacity of 7,854 gallons. An Oxidation ditch with a total dimension of 106.5 ft. X 124.5 ft. with 3
channels. Channel 1 measures 52 ft. X 15 ft. X 9 ft. with a capacity of 350,000 gallons. Channel 2
measures 36 ft. X 15 ft. X 9 ft. with a capacity of 250,000 gallons. Channel 3 measures 20 ft. X 15 ft. X
9 ft. with a capacity of 150,000 gallons. The 3 channels have a total of six rotor aerators. The plant has
dual final clarifers with a diameter of 35 ft.X 13.5 ft and a capacity of 97,104 gallons each, dual chlorine
contact chambers measuring 32.3 ft X 11.6 ft. X 6 ft. with a capacity of 16,918 gallons. and SO2
dechlorination. Also in place is a rectangular effluent flow weir, cascade post aeration, influent and
effluent samplers, a DAF sludge thickener which has never been in operation, a return sludge pumping
station with dual pumps. The pre-existing package plant was converted to aerobic digesters with dual
blowers and the final clarifer was converted to a gravity sludge thickener.The aerobic dibesters consists of
4 metal tanks, holding 10,500 gallons, 9627 gallons, 19,400 gallons and 121,445 gallons or a total of
160,972 gallons.. The thickened sludge pump station pumps to a sludge holding tank that measures
56 ft.diameter X 20 ft. with a capacity of 368,279 gallons. The sludge holding tank has a sludge
recirculating truck loading pump station with dual pumps. The plant also has a caustic feed system with a
recirculation pump and dual feed pumps.
