• Toxicity test results shall be filed with the Water Sciences Section no later than 30 days after the end of the reporting
ep riod(eg,January test result is due by the end of February).

which have not received a facility classification. In these cases,a duly authorized facility representative must sign the AT form.
The AT form must also be signed by the performing lab supervisor.
➢ FAILED TESTS:
• Toxicity test condition language contained in your NPDES permit may require use of multiple concentration toxicity testing
upon failure of any single quarterly toxicity test. If the initial pass/fail test fails or if the chronic value is lower than the permit
limit,then at least two multiple concentration toxicity tests(one per month)will be conducted over the following two months.
As many analyses as can be completed will be accepted. If your NPDES permit does not require use of multiple concentration
toxicity testing upon failure of any single quarterly test,you may choose to conduct either single concentration toxicity testing
or multiple concentration toxicity testing per the Division's WET enforcement initiatives effective July 1,1999. Follow-up
multiple concentration toxicity testing will influence the Division's enforcement response.
➢ INVALID TESTS:
• If you receive notification from your contract laboratory that a test was invalidated,you should immediately notify the Water
Sciences Section at(919)743-8424 and provide written documentation indicating why the test was invalidated and the date
when follow-up testing will occur.
➢ TESTING MONTHS:
• Toxicity testing months are specified by the NPDES Permit,except for NPDES Permits which contain episodic toxicity
monitoring requirements(eg,if the testing months specified in your NPDES permit are March,June,September,and
December,then toxicity testing must be conducted during these months).
EPISODIC MONTIORING:
• If your NPDES Permit specifies episodic monitoring and your facility does not have a discharge from January 1-June 30,then
you must provide written notification to the Water Sciences Section by June 30 that a discharge did not occur during the first
six months of the calendar year.
➢ NO DISCHARGE:
➢ If your facility is required to conduct toxicity testing during a month in which no discharge occurs,you should complete the
information block located at the top of the AT form indicating the facility name,permit number,pipe number,county and the
month/year of the subject report. You should also write"No Flow"on the AT form,sign the form and submit following normal
