The Division may re -open and modify this permit if required in the event that the Division:
o Adopts new freshwater quality standards for ammonia.
o Develops a site -specific management strategy pursuant to T15A NCAC 2B .0110 in order to
protect endangered or threatened aquatic species in the receiving water.
If instream monitoring indicates ammonia concentrations are above protective concentrations for mussels
and the WWTP is identified as the cause, the Permittee will be required to evaluate options to reduce
effluent ammonia concentrations (including outfall redesign), and report to the Division within 120 days
of notification by the Division.
A. (3) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
[G.S. 143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program
reports and specify that, if a state does not establish a system to receive such submittals, then permittees
must submit monitoring data and reports electronically to the Environmental Protection Agency (EPA).
The final NPDES Electronic Reporting Rule was adopted and became effective on December 21, 2015.
NOTE: This special condition supplements or supersedes the following sections within Part u of this
permit (Standard Conditions for NPDES Permits):

Monitoring Reports
I. Reporting Requirements fSupersedes Section D. 2. and Section E. 5. a
Effective December 21, 2016, the permittee shall report discharge monitoring data electronically using
the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. Until such time that the state" s
eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation
(CROMERR), permittees will be required to submit all discharge monitoring data to the state
electronically using eDMR and will be required to complete the eDMR submission by printing,
signing, and submitting one signed original and a copy of the computer printed eDMR to the following
address:

1617 Mail Service Center
Raleigh, North Carolina 27699-1617
Page 5 of 7

Permit NCO087891
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility
being physically located in an area where less than 10 percent of the households have broadband
access, then a temporary waiver from the NPDES electronic reporting requirements may be granted
and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1.1, 2, 3) or alternative
forms approved by the Director. Duplicate signed copies shall be submitted to the mailing address
above. See "How to Request a Waiver from Electronic Reporting" section below.
Regardless of the submission method, the first DMR is due on the last day of the month following the
issuance of the permit or in the case of a new facility, on the last day of the month following the
commencement of discharge.
Starting on December 21, 2020, the permittee must electronically report the following compliance
monitoring data and reports, when applicable:
Sewer Overflow/Bypass Event Reports;
Pretreatment Program Annual Reports; and
Clean Water Act (CWA) Section 316(b) Annual Reports.
The permittee may seek an electronic reporting waiver from the Division (see "How to Request a
Waiver from Electronic Reporting" section below).
2. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to the
Division. Requests for temporary electronic reporting waivers must be submitted in writing to the
Division for written approval at least sixty (60) days prior to the date the facility would be required
under this permit to begin submitting monitoring data and reports. The duration of a temporary waiver
shall not exceed 5 years and shall thereupon expire. At such time, monitoring data and reports shall be
submitted electronically to the Division unless the permittee re -applies for and is granted a new
temporary electronic reporting waiver by the Division. Approved electronic reporting waivers are not
transferrable. Only permittees with an approved reporting waiver request may submit monitoring data
and reports on paper to the Division for the period that the approved reporting waiver request is
effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found on the
following web page:

Water Quality
Process Diagram Narrative Description
Permitting Section
Wastewater:
1. Wastewater enters a manhole where it is mixed with filter backwash and digester supernatant.
2. The wastewater pass through a bar screen to remove large objects.
3. Wastewater from the bar screen enters the influent valve vault where flow is directed to one of
two sequencing batch reactor (SBR) tanks.
4. Wastewater enters one of the two SBR tanks.
5. Wastewater is aerated and mixed with sludge in the SBR tank, then allowed to settle before
decanting.
6. Decanted wastewater from the SBR tanks enters the post equalization basin.
7. Wastewater from the post equalization basin is directed through one of the two tertiary disk
filters.
8. Wastewater from both tertiary disk filters enters the UV disinfection system.
9. Treated effluent is discharged to the South Toe River.
Sludge:
1. Waste sludge from the SBR tanks is evacuated to the digester.
2. Waste sludge from the digester is loaded onto trucks for disposal at the Town of Burnsville
WWTP (NC0020290).

Residuals Management Plan
East Yancey Wastewater Treatment Plant
The East Yancey Wastewater Treatment Plant (WWTP) will include a sludge holding tank.
Residuals will be stored for a period of time, until they are hauled to the Town of Burnsville's
WWTP and dewatered in their belt filter press. The Town of Burnsville has an agreement with
the East Yancey Water and Sewer District to operate the proposed East Yancey WWTP.
Burnsville personnel will haul sludge via sludge trucks from the sludge loading station at the
East Yancey WWTP to the Burnsville WWTP.
Per 15A NCAC 02H a minimum of 30 days of solids storage is required. Due to the remote
location of this plant and the method of sludge disposal it is recommended to provide 75 days of
storage. Solids will be produced at a rate of 100 lbs/day based on an average flow of 125,000 gpd
and 0.8 lbs solids per 1000 gallons of wastewater (Metcalf and Eddy, Wastewater En ing eering 3"d
Edition, pg 773) (125,000 gpd x 0.8 lbs solids / 1000 gal. = 100 lbs solids / day). Assuming a 1.5 %
solids concentration (Metcalf and Eddy, Wastewater Engineering 3'd Edition, pg 774)
approximately 59,050 gallons of sludge will be produced in 75 days (100 lbs solids / day x 1/ (62.4
lbs / cubic foot water x 1.015 (specific gravity of 1.5% sludge) x 0.015 (solids content) = 105.26
cubic feet per day = 787.3 gpd * 75 days = 59050 gal sludge produced in 75 days). The proposed
sludge holding tank is sized to hold approximately 62,800 gallons (32' x 17.5' x 15' water level =
8400 CF = 62,832 gallons) which is greater than 59,050 gallons therefore the sludge storage
requirement is met.
The belt filter press at the Burnsville WWTP was installed in 2000. It was designed to handle
sludge not only from the Burnsville WWTP, but also from the future East Yancey WWTP. The
maximum solids produced at the Burnsville WWTP were calculated to be 664 lbs/day (800,000
gpd x 0.83 lbs/ 1000 gal. = 664 lbs/day). However, the belt filter press was sized based on a total
flow rate of 1.1 mgd to account for solids coming from the future East Yancey WWTP
(1,100,000 gpd x 0.83 lbs/1000 gal. = 913 lbs/day). The 913 lbs/day capacity of the belt filter
press is therefore large enough to handle sludge from both the Burnsville WWTP (maximum
solids rate of 664 lbs/day) and the East Yancey WWTP (100 lbs/day).
