A. (7.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs)
and specify that, if a state does not establish a system to receive such submittals, then permittees must
submit DMRs electronically to the Environmental Protection Agency (EPA). The Division anticipates
that these regulations will be adopted and is beginning implementation in late 2013.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit (Standard Conditions for NPDES Permits):
• Section B. (11.)
• Section D. (2.)
• Section D. (6.)

Monitoring Reports
1. Reporting [Supersedes Section D. (2.) and Section E. (5.) (a)]
Beginning no later than 270 days from the effective date of this permit, the permittee shall begin
reporting 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:
NC DENR / DWR / Information Processing Unit
ATTENTION: Central Files / eDMR
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
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.
Requests for temporary waivers from the NPDES electronic reporting requirements 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 using eDMR. Temporary waivers shall be
valid for twelve (12) months and shall thereupon expire. At such time, DMRs shall be submitted
electronically to the Division unless the permittee re -applies for and is granted a new temporary
waiver by the Division.
Page 9 of 11

Permit NC0026646
Information on eDMR and application for a temporary waiver from the NPDES electronic
reporting requirements is found on the following web page:
http://portal.ncdenr.org/web/wq/admin/bog/ipu/edmr
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.
2. Signatory Requirements [Supplements Section B. (11.) (b) and supersedes Section B. (11.) (d)1
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part

SUMMARY
The Town of Pilot Mountain operates a wastewater treatment plant with a capacity of 1.5 MGD
but operated at the reduced flow of 0.5 MGD. The permit includes effluent limits for both flow
phases. If annual average flow increase above 90% of 0.5 MGD (0.45 MGD) the permittee shall
obtain authorization from the Division to operate at the 1.5 MGD flow. The town does not
expect to go to the higher flow rate within the next permit cycle.
The wastewater treatment system consists of influent pump station, grit removal, aeration
basin, two clarifiers, chlorination, de -chlorination, post aeration, effluent force main and
sludge holding tank.
RECEIVING STREAM
This facility discharges to the Ararat River in the Yadkin River Basin, classified C waters, HUC

Notices of violation were issued for one exceedance of BOD weekly average, one monthly
average and four weekly average exceedances for fecal coliform, and three monthly average and
seven weekly average exceedances for TSS. A reasonable potential analysis was performed for
Lead, Copper and Zinc. See attached RPA spreadsheet for results.
Mercury Evaluation
A mercury evaluation was conducted in accordance with the Permitting Guidance developed for
the implementation of the statewide Mercury TMDL to determine the need for a limit. Based on
dilution the water quality based effluent limitation (WQBEL) for mercury is 1,290 ng/1. The
technology based effluent limit (TBEL) is 47 ng/l. Three mercury samples were reported with
the permit application. The highest value was 6.96 ng/1 and the average was 6.33 ng/1. Based
on these results the permit will not include a mercury limit, only monitoring once every five
years.
LIMITS AND MONITORING REQUIREMENTS:
Current conditions, as well as the basis for the limits are summarized in Table 2.

INSTREAM MONITORING:
The permit requires instream monitoring at one upstream location and two downstream
locations. The permittee is a member of the Yadkin -Pee Dee River Basin Association, instream
monitoring is waived.
PRIORITY POLLUTANT ANALYSIS:
The application includes the results of three priority pollutant analyses. There were no
pollutants detected in the scan.
AQUATIC TOXICITY TESTING
Permit requires chronic toxicity, ceriodaphnia dubia, 1% (0.5). The facility consistently passed
all the toxicity tests.
SUMMARY OF PROPOSED CHANGES:
1. Based on the results of the RPA monitoring for lead was eliminated from the permit and
monitoring for copper and zinc were reduced to quarterly.
2. A condition was added to the permit with requirements for sampling mercury once
every permit cycle.
3. The permit includes a special condition with new requirements for electronic reporting
of DMRs.

SUPPLEMENTAL APPLICATION INFORMATION
PART E. TOXICITY TESTING DATA
POTWs meeting one or more of the following criteria must provide the results of whole effluent toxicity tests for acute or chronic toxicity for each of the
facility's discharge points: 1) POTWs with a design flow rate greater than or equal to 1.0 mgd; 2) POTWs with a pretreatment program (or those that are
required to have one under 40 CFR Part 403); or 3) POTWs required by the permitting authority to submit data for these parameters.
• At a minimum, these results must include quarterly testing for a 12-month period within the past 1 year using multiple species (minimum of two
species), or the results from four tests performed at least annually in the four and one-half years prior to the application, provided the results
show no appreciable toxicity, and testing for acute and/or chronic toxicity, depending on the range of receiving water dilution. Do not include
information on combined sewer overflows in this section. All information reported must be based on data collected through analysis conducted
using 40 CFR Part 136 methods. In addition, this data must comply with QA/QC requirements of 40 CFR Part 136 and other appropriate QA/QC
requirements for standard methods for analytes not addressed by 40 CFR Part 136.
• In addition, submit the results of any other whole effluent toxicity tests from the past four and one-half years. If a whole effluent toxicity test
conducted during the past four and one-half years revealed toxicity, provide any information on the cause of the toxicity or any results of a
toxicity reduction evaluation, if one was conducted.
• If you have already submitted any of the information requested in Part E, you need not submit it again. Rather, provide the information
requested in question E.4 for previously submitted information. If EPA methods were not used, report the reasons for using alternate methods.
If test summaries are available that contain all of the information requested below, they may be submitted in place of Part E.
If no biomonitoring data is required, do not complete Part E. Refer to the Application Overview for directions on which other sections of the form to
complete.
