Dear Ms. Payne:
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 July 3, 2007.
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

Permit NC0020940
A. (3) CHRONIC TOXICITY PERMIT LIMIT (Quarterly at 0.925 MGD)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or
significant mortality to Ceriodaphnia dubia at an effluent concentration of 1.5%.
The permit holder shall perform at a minimum, quarterlu 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, using the
parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWQ
Form AT-3 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch 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 Branch 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 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.

A. (4) CHRONIC TOXICITY PERMIT LIMIT (Quarterly at 1.4 MGD)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or
significant mortality to Ceriodaphnia dubia at an effluent concentration of 2.2%.

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

BACKGROUND
The Murphy WWTP (Class III) has a phased permit with permitted flows of 0.925 MGD and 1.4
MGD, it serves 1,310 people. The Town of Murphy currently has a pretreatment program with
the Division of Water Quality's Pretreatment Unit. The permit will continue to require the Town
to continue to implement its pretreatment program. The facility has not requested any changes to
the permit.
REASONABLE POTENTIAL ANALYSIS

For the last several months, we've been trying to revise which NPDES
permits we're going to overview. Earlier this week, we finally came up
with an updated list for facilities discharging to 303(d) streams.
Based on that new list, we will not be reviewing these permits. thanks

Subject: Town of Murphy, NPDES Permit # NC0020940, Permit Renewal.
The Town of Murphy is requesting renewal of its NPDES wastewater permit. The
current permit took effect on January 1, 2004 and is due to expire August 31, 2007.
No modifications have been made to this facility since its construction, the issuance
of the current permit, and our current operations.
The sludge generated by the Town of Murphy is still processed in aerobic digesters
until oxidized and then it is run through our sludge press. Final disposal of sludge will be
in the Cherokee County Landfill. All analyses and requirements are performed by the
Town of Murphy to ensure local and state regulations are met.
Sincerely,
Anna Payne
Town Manager

Subject: Pollutant List Data
1. Per your instructions, I did not fill out the pollutant list on the application form.
As requested I attached copies of the data sheets from the lab that does our
testing.
2. I will send in the February and March PPA sampling results as soon as they are
received.
3. I also wanted to note that our fecal count was high several times during this
period. This was a result of an unusual failure with our CL2 smartvalve. It took
us months to pin down the exact cause of the erratic fecal counts. It eventually
took the replacement of the smartvalve unit itself to correct the problem. We
have since been well within our fecal limits.

SBR PROCESS FLOW DIAGRAM
The "process flow diagram" for the SBR system consists of two SBR treatment tanks
which aerate the incoming wastewater and then is allowed to settle before discharged to
the post equalization tank. Sludge wasting is performed during the discharge sequence.
The system consists of two sludge digesters and a sludge press. The discharged
wastewater in the equalization tank is allowed to settle and is pumped off into the
chlorine contact tank and then sulfur dioxide is added before discharging to the river. A
back-up generator is onsite for any power failure.
