A. (3) ACUTE TOXICITY PASS/FAIL PERMIT LIMIT (0.5 MGD)
[15A NCAC 02B.02001
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 March, June, September and December. 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.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will
begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement will
revert to quarterly in the months specified above.
All toxicity testing results required as part of this permit condition will be entered bn the Effluent Discharge
Monitoring Form (MR -1) for the month in which it was performed, using the parameter code TGE6C
Additionally, DWR Form AT -2 (original) is to be sent to the,following address:

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 until such time that a single test is passed. Upon passing, this monthly test
requirement will revert to quarterly in the months specified above Assessment of toxicity compliance is based on
the toxicity testing quarter, which is the three-month time interval that begins on the first day of the month in
which toxicity testing is required by this permit and continues until the final day of the third month
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 mimmum 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.

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.

waiver request may submit monitoring data and reports on paper to the Division for the period that the
approved reporting waiver request is effective.
