> Toxicitv test results shall be riled with the Environmental Sciences Branch no later than 30 days after the end of the
reporting period (eg, January test result is due by the end of February).
> 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.
> Toxicity testing months are specified by the NPDES, Permit, except for NPDES Permits which contain episodic toxicity
monitoring requirements (eg, it the testing months specified in your NPDES permit are March, June, September, and
December, then toxicity testing must be conducted during these months).
> 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, the permittee will
revert to the quarterly months specified in the permit. Please note that your permit may or may not contain this language.
)k It 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 Environmental Sciences Branch by June 30 that a discharge did not occur
during the first six months of the calendar year.
If you receive notification frorn your contract laboratory that a test was invalidated, you should immediately notify the
Environmental Sciences Branch at [phone] and provide written documentation indicating why the test was
invalidated and the date when follow-up testing will occur.
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 procedures,
The Aquatic Toxicity Test forms shall be signed by the facility's Operator in Responsible Charge (CRC) except for facilities
