A. (2.) ACUTE TOXICITY MONITORING (MONTHLY) [15A NCAC 02B.0500]
The permittee shall conduct acute toxicity tests on a monthly basis using protocols defined as definitive
in EPA Document EPA-82 I -R-02-012 entitled "Methods for Measuring the Acute Toxicity of Effluents
and Receiving Waters to Freshwater and Marine Organisms." The monitoring shall be performed as a

purposes must be obtained during representative effluent discharge and shall be performed at the
NPDES permitted final effluent discharge below all waste treatment processes.
The parameter code for - Pimephalespromelas is TAA6C. All toxicity testing results required asp of
this permit condition will be entered electronically using the Division's eDMR system for the month in
which it was performed, using the appropriate parameter code. Additionally, DWR Form AT-1
(original) is to be sent to the following address:

days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all

signature.
Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is

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

retention of untreated wastes or maintenance during normal periods of equipment downtime. This
condition is not satisfied if adequate backup equipment should have been installed in the exercise of
reasonable engineering judgment to prevent a bypass which occurred during normal periods of
equipment downtime or preventive maintenance; and
(C) The Permittee submitted notices as required under Paragraph b. of this section.
(2) Bypass from the collection system is prohibited and the Permit Issuing Authority may take enforcement
action against a Permittee for a bypass as provided in any current or future system -wide collection system
permit associated with the treatment facility.
