[15A NCAC 02B.0200 et seq.]

The permit holder shall perform at a minimum, quarterly monit using test p ures outlined in
the "North Carolina Ceriodaphnia Chrpnic Effluent Bioassay Pro ure," (Revised mber 2010, or
subsequent versions) or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised December 2010, or subsequent versions)e tests wiM be performed during the months of
February, May, August, and November. These ionths signify the first month of each three-month
toxicity testing quarter assi to the facility. Effluent sampling for thi esting must be obtained during
representative effluent disc shall bellormed at the NPDESinitted final effluent discharge
below all treatment p1cesse's.
If the test procedure performed as the first test of an single quarter results in a failure or ChV
below the permit limit, then multiple -concentration ting shall be performed at a minimum, in
each of the two following months as described in "N Carolina Phase II Chronic Whole
Effluent Toxicity Test Procedure" (Revised -December 2010, or subsequent versions).
All toxicity ' g results requ as part of this permit condition will be entered electronically using
the Division's eDMR system for the months ix?which tests were performed, using the parameter code
TGP3B for the p it results and THP3B for the Chronic Value. Additionally, DWR Form AT-3

Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate

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, monitoring

testing quarter, which is the three-month time inte al that begins on the first day of the month in which
toxicity testing is required by this permit and cons until the final day of the third month.
Should any test data from this monitoring requiremen sts performed by the Carolina Division
