Division personnel have reviewed and approved your application for 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 May 9, 1994 (or as subsequently amended).
This final permit includes no major changes from the draft permit sent to you on April 28, 2004.
This permit includes a TRC limit that will take effect on February 1, 2006. If you wish to install
dechlorination equipment, the Division has promulgated a simplified approval process for such projects. Guidance
for approval of dechlorination projects is attached.
If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to
you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of
this letter. This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina
General Statutes, and filed with the Office of Administrative Hearings (6714 Mail Service Center, Raleigh, North

The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised November 1995, or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or significant
mortality is 3 % (defined as treatment two in the procedure document). The permit holder shall perform
quarterly monitoring using this procedure to establish compliance with the permit condition. The tests will be
performed during the months of January, April, July, and October. Effluent sampling for this testing shall be
performed at the NPDES permitted final effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B.
Additionally, DWQ Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of Water Quality
4401 Reedy Creek Road
Raleigh, North Carolina 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements performed
in association with the toxicity tests, as well as all dose/response data. 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 Branch at
the address cited above.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will
begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement will
revert to quarterly in the months specified above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this monthly test
requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of
Water Quality indicate potential impacts to the receiving stream, this permit may be re -opened and modified to
include alternate monitoring requirements or limits.
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.

SUMMARY
This facility is a major municipal treatment plant operating in Surry County that serves 1300
people. Town has separate sewer collection system. Facility has a permitted flow of 1.5 MGD
discharging into Ararat River. For the past 2 years annual average flow varied within the range
of 0.342-0.372 MGD. The Ararat River is on the 303 d list due to biological impairment,
sediment is listed as one of the main causes of impairment. The main potential sources of
pollution listed on 303d list are urban runoff, agriculture and municipal wastewater. The Town
of Pilot Mountain has 2 significant industrial users and a full-scale pretreatment program.
REASONABLE POTENTIAL ANALYSIS
The following parameters are monitored through the permit: Cd, Cn, Cu, Zn, Ag, The following
parameters are monitored quarterly through the pretreatment program: As, Cd, Cr, Cu, Pb, Hg,
Mo, Ni, Se, Zn, Cn. Reasonable potential analyses were conducted forall the parameters
monitored in the permit and through the pretreatment program (see attached).

The facility has been consistently passing its WET tests with one exception. The toxicity test
failed during October 2002. DWQ has notified the facility about steps they will be required to
take under the Copper and Zinc Action Level Policy if they fail two or more toxicity tests
during a calendar quarter.
COMPLIANCE SUMMARY:
Page 1
Version: June 15, 2004

DMRs have been reviewed for the period January 2000 through October 2003. Facility has a
mixed compliance record. During review period following limit violations have occurred:
10/17/00 — Cn daily max.; 12/2000 — NH3 weekly average; 12/12/00 — Cn daily max.; 01/2001 —
TSS weekly average for 3 weeks and TSS monthly average; 01/01/00 — Cn daily max.; 02/2001
BOD monthly average and TSS monthly average; 02/12/01 — Cn daily max.; 02/18/01 — Cn
daily max.; 02/27/01 — Cn daily max; 06/27/01 — Cn daily max; 07/03/01 — Cn daily max.;
07/26/01 — Cn daily max.; 6/23/03 - Cn daily max., TSS weekly average and monthly average.
A compliance evaluation inspection conducted on October 23, 2003 found that facility is well
maintained and properly operated: A few minor issues that needed to be addressed were the
method for collecting composite samples and monitoring frequencies for temperature, Cu, Ag,
and Zn. An on -site inspection conducted on December 14, 2001 did not find any operational or
maintenance problems, although it was noted that there is excessive amounts of sludge stored
on the property. A compliance evaluation inspection conducted on October 19, 2000 found
following deficiencies: too much sludge stored on the property, and some minor issues with
DMRs and records.
INSTREAM MONITORING:
Instream monitoring is required for temperature, dissolved oxygen, fecal coliform, and
conductivity. The facility is a member of the Yadkin -Pee Dee Monitoring Coalition,
and all their instream monitoring is conditionally waived for the duration of their
membership in the Coalition. Analysis of DO, temperature and conductivity data
showed that facility has no negative impact on DO and temperature of the stream (table
is attached).
PROPOSED CHANGES:
• Monitoring Frequencies: Weekly monitoring for lead has been introduced due to the
implementation of the new permit limit. Monitoring for cadmium and cyanide has been
reduced to 2/month due to the elimination of the limit. Monitoring for oil and grease has
been reduced to weekly based on effluent data.
• Limits: Based on Reasonable Potential Analysis, a limit is being introduced for lead. A
weekly average limit for ammonia nitrogen has been added to the permit, and a daily
maximum limit for total residual chlorine has been added to the permit. Limits for
cadmium and cyanide have been eliminated based on Reasonable Potential Analysis.
• Priority pollutant monitoring on an annual basis has been added to fulfill the permit
application requirement in the future.
Existing permit limits and recommended limits/monitoring are summarized in the table below:
