amended).
This modified permit includes the following changes from your current permit:
Outfall 002 has been deleted. Staff from the NC DENR Mooresville Regional Office have
confirmed that the outfall has been properly sealed.
If any parts, measurement frequencies or sampling requirements contained in this modification are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30)
days following receipt of this letter. This request must be in the form of a written petition, conforming to
Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative Hearings

1. All "effluent" samples shall be collected after the point of convergence of all dewatering streams and prior to
the point of connection with the storm sewer.
2. The grab sample for oil and grease should be skimmed from the surface in a quiescent zone, such as a holding
tank, if possible.
3. If lead is detected at 25 µg/L or lower during the first eight sampling events, lead monitoring is no longer
required and may be discontinued for the remainder of the permit term. If lead is detected at > 25.0 µg/L
during any of the first eight sampling events, lead monitoring must be continued for the remainder of the
permit term.
4. If this pollutant is not detected above method detection limits during the first eight sampling events, then
monitoring is no longer required and may be discontinued for the remainder of the permit term. If the
pollutant is detected during any of the first eight sampling events, monitoring must continue for the
remainder of the permit term.
5. Chronic Toxicity (Cerfodaphnia) P/F at 90%; March, June, September, and December [see A. (2)].
There shall be no discharge of floating solids or foam visible in other than trace amounts.

Permit NC0084226 t
A. (2) CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia
dubia at an effluent concentration of 90%.
The permit holder shall perform at a minimum, ua arterl monitoring using test procedures outlined in the "North Carolina
Cmodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North Carolina Phase
ll Chronic Whole Effluent Toxicity Test Procedure" (Revised February 1998) or subsequent versions. The tests will be
performed during the months March, June, September, and December. Effluent sampling for this testing shall be performed
at the NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first best of any single quarter results in a failure or ChV below the permit limit, then
multiple -concentration testing shall be performed at a minimum, in each of the two following months as described in "North
Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest concentration
having no detectable impairment of reproduction or survival and the lowest concentration that does have a detectable
impairment of reproduction or survival. The definition of "detectable impairment," collection methods, exposure regimes,
and further statistical methods are specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be -entered on the Effluent Discharge Monitoring Form
(MR-1) for the months in which tests were performed, using the parameter code TGP3B for the pass/fail results and THP3B
for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than 30 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 concentration/response
data, and be certified by laboratory supervisor and ORC or approved designate signature. Total residual chlorine of the
effluent toxicity sample must be measured and reported if 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 bop 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" m the comment area of the
form. The report shall be submitted to the Environmental Sciences Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be required
during the following month
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water Quality
indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include alternate monitoring
requirements or limits.
If the Permittee monitors any pollutant more frequently then required by this permit, the results of such monitoring shall be
included in the calculation & reporting of the data submitted on the DMR & all AT Forms submitted.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism survival,
minimum control organism reproduction, 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 the month of the initial
monitoring.

RE: NC0088226 permit mod
Hi Charles,
Since Outfall 002 is under concrete as evidenced by John and I during an inspection last month, I personally
do not see any reason why it should not be taken off the permit,

Marcia - the permit mod to delete outfall 002 at the Wachovia dewatering site is ready to issue. Any reason I should not
issue it?
