Permit NC0085979
A.(2.) ACUTE TOXICITY MONITORING(QUARTERLY)
[15A NCAC 02B .0500 et seq.]
The Permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined in the North
Carolina Procedure Document entitled"Pass/Fail Methodology For Determining Acute Toxicity In A Single
Effluent Concentration"(Revised-December 2010 or subsequent versions). The monitoring shall be performed
as a Fathead Minnow(Pimephales promelas)24 hour static test.The effluent concentration at which there may
be at no time significant acute mortality is 90% (defined as treatment two in the procedure document). 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.
The parameter code for Pimephales promelas is TGE6C. All toxicity testing results required as part of this
permit condition will be entered on the Effluent Discharge Form(MR-1)for the month in which it was
performed,using the appropriate parameter code.Additionally,DWR Form AT-2 (original)is to be sent to the
following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1623 Mail Service Center
Raleigh,North Carolina 27699-1623
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 any month,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 either these monitoring requirements 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 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. (3.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
[G.S. 143-215.1(b)]
Proposed federal regulations require electronic submittal of all discharge monitoring reports(DMRs). The

Section D. (2.) Reporting
Section D. (6.) Records Retention
Section E. (5.) Monitoring Reports
1. Reporting [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)intemet 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 intemet. 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, signing,and submitting one signed original and a copy of the computer printed eDMR
to the following address:
NC DENR/DWR/Information Processing Unit
ATTENTION: Central Files/eDMR
1617 Mail Service Center
Raleigh,North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility being
physically located in an area where less than 10 percent of the households have broadband access,then a
temporary waiver from the NPDES electronic reporting requirements may be granted and discharge monitoring
data may be submitted on paper DMR forms(MR 1, 1.1,2,3)or alternative forms approved by the Director.
Duplicate signed copies shall be submitted to the mailing address above.
Requests for temporary waivers from the NPDES electronic reporting requirements must be submitted in writing
to the Division for written approval at least sixty(60)days prior to the date the facility would be required under
this permit to begin using eDMR. Temporary waivers shall be valid for twelve(12)months and shall thereupon
expire. At such time,DMRs shall be submitted electronically to the Division unless the permittee re-applies for
and is granted a new temporary waiver by the Division.
Information on eDMR and application for a temporary waiver from the NPDES electronic reporting
requirements is found on the following web page:

For eDMR submissions,the person signing and submitting the DMR must obtain an eDMR user account and
login credentials to access the eDMR system. For more information on North Carolina's eDMR system,
registering for eDMR and obtaining an eDMR user account,please visit the following web page:
