RE: NPDES Renewal AUG 2 8 1010
Western Justice Academy WWTP
Edneyville, Henderson County,NC NCDEQ/pINRo.yapES
Dear Ms. Thedford,
Johnston Environmental, PLLC (JE), on behalf of'Henderson County is submitting this National
Pollutant Discharge Elimination System(NPDES)permit renewal for the Western Justice
Academy wastewater treatment plant(WJA WWTP). WJA WWTP currently discharges under
Permit NC0086070 which expires November 30, 2020.
In 2011,the North Carolina Department of Environmental Quality (NCDEQ) Division of Water
Resources (DWR)issued a modified NPDES permit to the WJA WWTP with a second-tier of
effluent limits and monitoring requirements(Part I A. (2))which would take effect when
monthly average flows exceed 0.01 million gallons per day (MGD). The second-tier
requirements impose lower and seasonal effluent limits for monthly and weekly average BOD5
and ammonia(NH3 as N).
Between April and June 2017 monthly average daily flows at the facility exceeded 0.01 MGD.
This far exceeded recorded average daily flows before and since this period as demonstrated in
Daily Monitoring Reports(DMRs). It was determined that the elevated flow for this period was
due to a combination of flow meter errors and increased flow due to major events occurring on
the JCA campus. These issues have been addressed and future elevated flows are not
anticipated.
After monthly average flows exceeded 0.01 MGD in three consecutive months between April
and June 2017,NCDEQ began reviewing the plant's historical flow data and decided to enforce
the second-tier permit starting July 2017. Although average monthly flows have not exceeded
5,000 gpd since July 2017, the NPDES permit does not revert to lower flow limits once the
10,000 gpd threshold is passed.
On Friday November 8, 2019 McGill Associates, on behalf of Henderson County,met with
Environmental Specialist, Daniel Boss and Regional Engineer, Tim Heim of NCDEQ Water
Resources—Water Quality Regional Operations at the Asheville Regional NCDEQ office. The
DEQ Asheville Regional Office was in support of changing the plant's permit to revert to the
permit limits associated with flows under 0.01 MGD at permit renewal.
1

Henderson County is requesting to revise the NPDES permit to allow the first-tier Part A(1)
limits to be enforced until monthly flows exceed 0.01 MGD in consecutive 4 months. By then the
second-tier permit requirements would be enforced. These effluent limits are outlined in Table 1.

Sludge Management
The WJA WWTP builds sludge slowly, due to the low influent flow. Sludge accumulation is.
monitored by the facility ORC and wasted to the digester to optimize facility operation. As the
need for sludge removal becomes apparent, sludge will be wasted to the digester where it will be
in the digester,the sludge is reduced and thickened for cost effective hauling. The sludge is
removed under an annual contract by Mike's Septic (828-775-1658)and transported to MSD of
Buncombe County waste treatment facility for disposal and the cost is paid by Henderson
County. Should the flow(and sludge generation) increase at this facility, the permittee will
respond by increasing the frequency in hauling.
Sincerely,
Deborah T. Johnston, PE
