Dear Ms. Johnston:
Division personnel have reviewed and approved your application for a renewal of the subject
permit. Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued
pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of
Agreement between North Carolina and the U.S. Environmental Protection Agency dated October
15, 2007 (or as subsequently amended).
The following changes have been incorporated into this renewal:
• 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.
The requirement to begin reporting discharge monitoring data electronically using the NC
DWR's Electronic Discharge Monitoring Report (eDMR) internet application has been added
to your NPDES permit. [See Special Condition A. (4.)] For information on eDMR, registering
for eDMR and obtaining an eDMR user account, please visit the following web page:

Permit NC0020567
A. (2) CHRONIC TOXICITY PERMIT LIMIT (Quarterly)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or
significant mortality to Ceriodaphnia dubia at an effluent concentration of 0.87%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures
outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised
February 1998, or subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity
Test Procedure" (Revised -February 1998) or subsequent versions. The tests will be performed
during the months of March, June, September and December. Effluent sampling for this testing
shall be performed at the NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or
ChV below the permit limit, then multiple -concentration testing shall be performed at a minimum, in
each of the two following months as described in "North Carolina Phase II Chronic Whole Effluent
Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric
mean of the highest concentration having no detectable impairment of reproduction or survival and
the lowest concentration that does have a detectable impairment of reproduction or survival. The
definition of "detectable impairment," collection methods, exposure regimes, and further statistical
methods are specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (Revised -February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the
Effluent Discharge Monitoring Form (MR-1) for the months in which tests were performed. If
reporting pass/fail results using the parameter code TGP3B, DWR Form AT-1 (original) is sent to the
below address. If reporting Chronic Value results using the parameter code THP3B, DWR Form AT-3
(original) is to be sent to the following address:
Attention: NC DENR / DWR / Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no
later than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical
measurements and all concentration/response data, and be certified by laboratory supervisor and
ORC or approved designate signature. Total residual chlorine of the effluent toxicity sample must be
measured and reported if chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity
monitoring is required, the permittee will complete the information located at the top of the aquatic
toxicity (AT) test form indicating the facility name, permit number, pipe number, county, and the
month/year of the report with the notation of "No Flow" in the comment area of the form. The report
shall be submitted to the Environmental Sciences Section at the address cited above. Should the
permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be
required during the following month. Should any test data from this monitoring requirement or tests
performed by the North Carolina Division of Water Resources indicate potential impacts to the
receiving stream, this permit may be re -opened and modified to include alternate monitoring
requirements or limits.
If the Permittee monitors any pollutant more frequently then required by this permit, the
results of such monitoring shall be included in the calculation and reporting of the data submitted
on the DMR and all AT Forms submitted.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival, minimum control organism reproduction, and appropriate environmental
controls, shall constitute an invalid test and will require immediate follow-up testing to be completed
no later than the last day of the month following the month of the initial monitoring.

Additional Toxicity Testing Requirements for Municipal Permit Renewal. Please note that
Municipal facilities that are subject to the Effluent Pollutant Scan requirements listed above are also
subject to additional toxicity testing requirements specified in Federal Regulation 40 CFR
122.21(j)(5). The US EPA requires four (4) toxicity tests for a test organism other than the test
species currently required in this permit. The multiple species tests should be conducted either
quarterly for a 12-month period prior to submittal of the permit renewal application, or four tests
performed at least annually in the four and one half year period prior to the application. These tests
shall be performed for acute or chronic toxicity, whichever is specified in this permit. The multiple
species toxicity test results shall be filed with the Aquatic Toxicology Branch at the following address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Contact the Division's Aquatic Toxicology Branch at 919-743-8401 for guidance on conducting the
additional toxicity tests and reporting requirements. Results should also be summarized in Part E
(Toxicity Testing Data) of EPA Municipal Application Form 2A, when submitting the permit renewal
application to the NPDES Permitting Unit.
A. (4.) 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.

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.
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 II, Section B. (11.) (a) or by a duly authorized representative of that
person as described in Part II, Section B. (11.)(b). A person, and not a position, must be
delegated signatory authority for eDMR reporting purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an
eDMR user account and login credentials to access the eDMR system. For more

Background
The Yadkin Valley Sewer Authority WWTP is a Class IV facility with a permitted flow of 1.8
MGD. The facility is 100% domestic and serves customers in Elkin. The facility provides
service for approximately 6,703 citizens of Elkin, Ronda and Jonesville. In addition to NPDES
Permit NC0020567, the Permittee also holds the non -discharge permit WQ0007349 for land
application of sludge. The facility has not requested any changes to the current NPDES permit.
Instream Monitoring, Verification of Existing Conditions and DMR Data Review
This facility discharges to the Yadkin River in subbasin 03-07-02 of the Yadkin -Pee Dee River
Basin. The Valley River is classified C waters at this point and is on the 2012-303(d) list for
turbidity standard violations. The facility is not required to monitor any instream parameters, so
no instream data were available for analysis.

The permit does not require monitoring for toxicants. However, the Division considered data
for parameters of concern in the EPA Form 2C that facility submitted for the renewal. The
majority of the parameters were not detected in the discharge. The Division reviewed the
following parameters that were detected in the discharge and have applicable state standards or
EPA criteria for Class C stream: Zn and Chloroform. Both of these parameters were below the
state standards/EPA criteria except for one sample of Zn that was detected at 51 ug/L (above the
standard of 51 ug/L) . Considering the in -stream waste concentration of only 0.87%, even Zn is
well below the allowable concentration and is not expected to violate the applicable water
quality standard.

• Fecal Coliforms limits in the permit are based on the North Carolina water quality
standards [15A NCAC 2B .0200].
• pH limits limit in the permit are based on the North Carolina water quality standards
[15A NCAC 2B .0200].
• TRC limit in the permit is based on the North Carolina water quality standards [15A

Summary of Proposed Changes
• 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.
The requirement to begin reporting discharge monitoring data electronically using the NC
DWR's Electronic Discharge Monitoring Report (eDMR) internet application has been
added to the permit. [See Special Condition A. (4.)]
• Monitoring frequency for Total Nitrogen and Total Phosphorus was reduced to Monthly
in accordance with the 15A NCAC 2B .0508.
