Subject: Change -Page to Correct Error
NPDES Permit NCO061719
Woodlake Country Club WWTP
Moore County
The Division of Water Resources (the Division) became aware of an error in your recently issued
permit (December 16, 2019). The instream waste concentration (IWC) in Section A. (5) does not
accurately reflect the IWC for a permitted flow of 0.5 MGD. In addition, all three toxicity
conditions were not updated to include information regarding electronic submittal of forms.
Accordingly, we hereby forward the modified permit pages to amend your permit updating the
aquatic toxicity conditions in Sections A. (4), A. (5), and A. (6). Please insert these change pages
into your existing permit and discard the old pages. We regret any inconvenience this causes your
organization.
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 any other Federal, State, or Local governmental permits that may be required.
If you have questions, or if we can be of further service, please contact Brianna Young at
[e-mail] or call [phone].
Respectfully,

Permit NCO061719
A. (4) CHRONIC TOXICITY PASS/FAIL MONITORING ONLY (QUARTERLY)
Permitted Flow of 0.3 MGD
[15A NCAC 02B. 0500 et seq.]
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 2.8 %. The testing
shall be performed as a Ceriodaphnia dubia 7-day pass/fail test. The tests will be performed during the
months of February, May, August, and November. 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 electronically using
the Division's eDMR system for the month in which it was performed, using the parameter code
TGP311. Additionally, DWR Form AT-1 (original) is to be sent to the following address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, NC 27699-1621
Or, results can be sent to the email, [e-mail].
Completed Aquatic Toxicity Test Forms shall be filed with the Water 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
Water Sciences Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, then
monthly monitoring will begin immediately. Upon submission of a valid test, 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 Resources 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.

The effluent concentration defined as treatment two in the procedure document is 4.6 %. The testing
shall be performed as a Ceriodaphnia dubia 7-day pass/fail test. The tests will be performed during the
months of February, May, August, and November. 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

A. (7) ELECTRONIC REPORTING OF MONITORING REPORTS
[G. S. 143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program
reports. The final NPDES Electronic Reporting Rule was adopted and became effective on December
21, 2015.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit (Standard Conditions for NPDES Permits):
• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)1
The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic
Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. Until such time that the state's
eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation
(CROMERR), permittees will be required to submit all discharge monitoring data to the state
electronically using eDMR and will be required to complete the eDMR submission by printing,
