Permit NC0024872
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 2.1%.
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 January, April, July, and October. 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: NC DENR / DWQ / 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, indude 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.
If the Permittee monitors any pollutant more frequently 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 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.

SUMMARY
Davie County owns a 1.5 MGD treatment plant at Cooleemee. Currently, only a
portion of the plant is used for treatment. In the past, due to underloading, the
Division cut back the flow from 3.5 MGD to 1.5 MGD. The City administers an
industrial pretreatment program to control the discharge of industrial and commercial
wastes into its collection system and treatment works. Industrial sources include 2
Significant Industrial Users. The permit will continue to require the City to
implement its pretreatment program
TOXICITY TESTING:
Current Requirement: Chronic P/F @ 2.1 % (also recommended with renewal)
Cooleemee has passed its whole effluent toxicity testing requirement since 2005.
COMPLIANCE SUMMARY:
The facility has had compliance problems. The most recent compliance evaluation
inspection conducted on April 11, 2008 determined that the facility "appeared to be
competently operated and maintained". The following Notices of Violation were issued
during the review period (2005 through 2009): 08/01/08 - TSS; 12/4/07 - TSS;
09/26/07 - 5 TSS violations; 04/02/07 - no field certification for pH, temperature,
and TRC; 03/30/07 - 3 BOD violations, 3 fecal coliform violations, and 2 TSS
violations (all during January of 2007); 02/02/07 - 3 TSS violations; 11/29/06 - 3
TSS violations; 11/7/06 - TSS; 06/26/06 - 4 TSS violations; 10/31/05 - 4 TSS
violations; 9/27/05 - 5 TSS violations; 09/06/05 - 4 TSS violations; 03/30/05 - 3
TSS violations; 03/02/05 - 2 TSS violations.
INSTREAM MONITORING:
Cooleemee is part of the Yadkin - Pee Dee Basin Association and is not required to
perform the instream monitoring. Unfortunately, the Association doesn't have a

monitoring station near the discharge (upstream of the discharge), which complicates
analyses of the effects of discharge on the water quality in the receiving stream.
However, such impact is unlikely due to high dilution.
PROPOSED CHANGES:
No changes are proposed.

Subject: Notice of Violation
Failure to Submit Renewal Application
NPDES Permit NC0024872

Davie County
Dear Permittee:
The subject permit's expiration date is April 30, 2009. Federal [40 CFR 122] and state (15A NCAC
2H.0105 (e)) regulations require that an application for permit renewal be filed at least 180 days prior to
expiration of the current permit. To satisfy this requirement, your renewal package should have been sent
to the Division postmarked no later than November 1, 2008.
As of this date, the Division has not received your renewal application. This is a violation of Part II.
B. 10. of your permit, which states "Any permittee that has not requested renewal at least 180 days prior to
expiration...will subject the permittee to enforcement procedures as provided in NCGS 143-215.6 and 33
USC 1251 et. seq.". To prevent an assessment of civil penalties you must submit a completed
permit application (see enclosed forms) no later than December 5, 2008.
Use the enclosed checklist to complete your renewal package. The checklist identifies the items you
must submit with the permit renewal application. If all wastewater discharge from your facility has ceased
and you wish to rescind this permit [or if you have any questions] please contact Charles H. Weaver of my
staff. His telephone number, fax number and e-mail address are listed at the bottom of this page.
Sincerely,

The following items are REQUIRED for all renewal packages:
o A cover letter requesting renewal of the permit and documenting any changes at the
facility since issuance of the last permit. Submit one signed original and two copies.
o The completed application form (copy attached), signed by the permittee or an
Authorized Representative. Submit one signed original and two copies.
o If an Authorized Representative (such as a consulting engineer or environmental
consultant) prepares the renewal package, submit written documentation showing the
authority delegated to any such Authorized Representative (see Part II.B.11.b of the
existing NPDES permit).
o A narrative description of the sludge management plan for the facility. Describe how
sludge (or other solids) generated during wastewater treatment are handled and
disposed. If your facility has no such plan (or the permitted facility does not generate
any solids), explain this in writing. Submit one signed original and two copies.
The following item must be submitted by Industrial or Municipal facilities
discharging industrial process wastewater:
o Industrial facilities classified as Primary Industries (see Appendices A-D to Title 40 of
the Code of Federal Regulations, Part 122) must submit a Priority Pollutant Analysis
(PPA) in accordance with 40 CFR Part 122.21. If the PPA cannot be completed by the
time you complete your application package, submit the application package without
the PPA. Submit the PPA as soon as possible after you receive the completed analyses.
The above requirement does NOT apply to non -industrial facilities.
