➢ Toxicity test condition language contained in your NPDES permit may requite 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 perrint 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, if the testing months specified in your NPDES permit are March, June, September, and December, then toxicity testing must
be conducted during these months),
> If your NPDES Permit specifies episodic monitoring and your facility does not have a discharge from January I -June Sit, 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.

Ms. Slachciak,
Thank you for submitting the supporting information requested for the April 11, 2012 effluent
toxicity test result for the CMUD-Sugari Creek WWTP. Alli relevant infim-nation has been
reviewed by Aquatic Toxicology Unit staff. The result of the April 11, 2012 test has been recorded
with a result of >I 00%.
To investigate the apparent difference in results obtained from the tests, we examined
documentation concerning sampling, testing, and lab procedures. Water quality parameters of the

25.4%. The difference between ETT Environmental, Inc. and Meritech, Inc. conductivity
measurements was 22.1 %. Both of these conductivity measurements were greater than would
normally be expected from past experience. The conductivity measurements between Meritech,
Inc. and Environmental Testing Solutions was 4.2%.

Mr. Ferrell also discussed with Ms. Robinson the bioassay cleaning procedure for the composite
sampler, and sample collection container. We recommend a bioassay cleaning procedure be
performed after each use in order to remove any toxic constituents that may remain in the
composite sampler tubing, or sample container. We recently sent instructions for the bioassay
cleaning procedure to you. If you or your staff have any questions regarding this procedure please
contact me or Mr. Ferrell at 919-743-8401 .
We have not determined that any of the labs involved violated any defined protocols. Each
laboratory produced appropriate chain -of -custody and quality assurance documentation. Effluent
water quality parameters measured at each laboratory were reasonably similar except for the above
described conductivity differences. Under these circumstances, it has been our policy to accept the
result which lies in favor of the discharging facility. A result of >I 00% has been, recorded for the
April 11, 2012 toxicity test. If a test result other than >I 00% was submitted, we remind you that
the CMUD-Sugar Creek WWTP monthly monitoring reports (DM R) submitted to the Division's
Central Files must be amended.
The effluent DMR facility information must be completely filled out (at the top of the sheet), and
the form should have "CORRECTED COPY" written or typed at the top.

Dear Mr. Shearin:
This is to inform you that a review of your toxicity self -monitoring report form for the month of February 2006
indicates a violation of the toxicity limitation specified in your NPDES Permit,
You should take whatever remedial actions are necessary to eliminate the conditions causing the effluent toxicity
violation(s). Your efforts may include conducting a Toxicity Reduction Evaluation (TRE), a site -specific study designed
to identify the causative agents of effluent toxicity, isolate the sources of toxicity, evaluate the effectiveness of toxicity
control options, and confirm reductions in effluent toxicity. Please be aware that North Carolina General Statutes provide
for assessment of civil penalties for violations of NPDES permit limitations and requirements.
