Dear Mr. Erickson:
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 October 15, 2007 (or as
subsequently amended).
This final permit contains the following changes to its terms from those found in the draft permit sent to
you on September 25, 2013.
• 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 monitoruig data electronically using the NC DWR's
Electronic Discharge Monitoring Report(eDMR) internet application has been added to your final
NPDES permit. [See Special Condition A. (3.)] For information on eDMR, registering for eDMR
and obtaining an eDMR user account, please visit the following web page:

• The name of the receiving stream as listed within the permit has been modified to be shown as an
"unnamed tributary to Irish Buffalo Creek"with the local name "Bakers Branch"noted
parenthetically.
Please note'that the receiving stream is listed as an impaired waterbody on the North Carolina 303(d)
Impaired Waters List. Addressing impaired waters is a high priority with the Division, and instream
data will continue to be evaluated. If there is noncompliance with pchnitted effluent limits and stream
impairment can be attributed to your facility, then mitigative measures may be required.
If any parts, measurement frequencies or sampling requirements contained in this pen-nit 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 Carolina 27699-6714). Unless
such demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may
require modification or revocation and reissuance of the permit. This permit does not affect the legal
requirements to obtain other permits which may be required by the Division of Water Resources or
permits required by the Division of Land Resources, the Coastal Area Management Act or any other
Federal or Local governmental permit that may be required.
If you have any questions concerning this permit, please contact Bob Sledge at telephone number (919)

The permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in the"North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure,"Revised December 2010, or subsequent
versions.
The effluent concentration defined as treatment two in the procedure document is 90 %. The testing shall be
performed as a Ceriodaphnia dubia 7-day pass/fail test. The tests will be performed during the months of
January,April,July and October. These months signify the first month of each three month toxicity testing
quarter assigned to the facility. Effluent sampling for this testing must be obtained during representative
effluent discharge and 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.

Environmental Sciences Section
1621 Mail Service Center
Raleigh,N.C. 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 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
Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, then monthly

quarterly in the months specified above.
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 ffequently then required by this permit, the results of such
monitoring shall be included in the calculation&reporting of the data submitted on the DMR&all AT Norms
submitted.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control

Outfall 001 discharge of filter backwash from the following treatment system:
equalization basin, clarifier, dechlorination, flow measurement, and sludge lagoon
C. Possible toxic impacts to surface waters: The facility dechlorinates to reduce the residual
chlorine levels added to the finished water process.
2. Residuals handling and utilization/disposal scheme: The settled solids and alum residuals are
pumped to the sludge lagoon. The sludge lagoon's decant water is discharged into Water Sewer
Authority of Cabarrus County (WSACC) wastewater collection system for final
treatment/disposal at the Rocky River WWTP. The Kannapolis WTP is permitted (local permit
ff 203) under WSACC's approved pretreatment program.
PART III OTHER PERTINENT INFORMATION
1. Special monitoring or limitations (including toxicity) requests: None requested.
PART IV - EVALUATION AND RECOMMENDATIONS
There have been no changes and/or modifications to this facility or the subject permit since the
permit was last issued. The facility appeared to be properly operated and well maintained during the site
visit; however, the sludge lagoon is full and the removal of sludge will need to be addressed in the
future. Note: -No sludge has been removed in many years. No effluent limit violations were reported
during the review of the previous twelve (12) month period (July 2012—June 2013).
It is recommended th t the permit be renewed as requested.

Permit 9 0006220
Kannapolis WTP
Rowan County
Dear Mr. Weaver,
We are requesting renewal of our NPDES Permit (No. 0006220) to discharge decanted
backwash water from the City of Kannapolis WTP. There have been no changes since the
last permit was issued.
Settled solids and Alum residuals are removed from our Sedimentation basins by way of
a Trac-Vac system. These solids are pumped to a Residuals Lagoon. Any decant water
from the lagoon is sent to the Rocky River WWTP, Cabarrus County (Local Pretreatment
No. 203). Solids/Alum Residuals will be removed from the lagoon and disposed of, per
regulations, when necessary.
Backwash water is sent to an Equalization basin and then pumped to a circular Clarifier,
which settles out the solids. A scraper arm pushes solids into a trough and then sends
them to the sludge pumping station where they are pumped to the Solids Lagoon. The
decant water is then de-chlorinated and sent to Bakers Branch of Irish Buffalo Creek..
Flow measurement is calibrated quarterly by CITI, Inc, Charlotte,NC.
Sincerely,
John Erickson
City of Kannapolis WTP Manager
