TWSA Plant # 3 is operated under the authority of the following permit, as issued by the North Carolina
Dept. Of Environment and Natural Resources: NC0063321 NPDES Discharge Permit

TWSA Plant # 3 discharges from one outfall into an unnamed tributary to the Chatooga River which is
classified as Class B-Trout ORW waters in the Savannah River Basin. The plant process is a conventional
activated sludge process with a design capacity of 0.200 million gallon/day. The plant consists of the
following unit processes, manually cleaned bar screen, extended air activated sludge with secondary
clarification, tertiary filters and chlorination and dechlorination facilities. The addition of a band screen at
the headworks would greatly improve operations and the quality of sludge the plant produces.

The average daily flow at the facility during the year 2021 was 0.090 mgd this represents 45.0% of plant
capacity and was a 2% decrease from the avg daily flow during 2020. The highest monthly average
during 2021 occurred in October and was recorded as .114 mgd. This represents 57% of total plant
capacity and represents a 4% increase from 2021. The highest daily recorded flow in 2021 was .267 mgd
and occurred October 7th, 2020. There were 6 days during 2021 that the daily flow exceeded plant
capacity.

This plant produced 90,000 gallons of waste sludge during 2021 This sludge was hauled by a private
contractor to TWSA Plant #1 for treatment. These residuals totaled 11.39 dry tons and represented 3.1%

of the total residuals generated by the Authorities facilities.

Overall performance of the TWSA #3 wastewater plant for the calendar year of 2021 was excellent. There
were no violations of permitted monthly, weekly or daily limits during the calendar year. On
average, there was a 96.6% reduction in the amount of pollutants in the water after treatment.

The permit for this facility was renewed effective November 1, 2017 and will expire on Aug 31st, 2022.
