A. (3) CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (Quarterly) at 0.5 MGD
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 1%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the `North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or
"North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or
subsequent versions. The tests will be performed during the months of January, April, July and October.
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 test 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 top 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" in 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 indude
alternate monitoring requirements or limits.
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.

Permit NC0026646
A. (4) CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (Quarterly) at 1.5 MGD

Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or

subsequent versions. The tests will be performed during the months of January, April, July and October.

Sergie, I have reviewed the draft for Pilot Mountain WWTP. Section A(1) should have
a chronic tox lim of 1.0% for 0.5 MGD. Section A(2) should have a chronic tox lim of
3.0% for 1.5 MGD. Section A(3) is correct. There is no mention of 1.5 MGD in A(4),
instead it lists 3.0 MGD with an incorrect tox lim of 3% (that would be 5t). Thanks
for forwarding the draft.

"The real work of men was hunting meat. The invention of agriculture was a giant step
in the wrong direction, leading to serfdom, cities, and empire. From a race of
hunters, artists, warriors, and tamers of horses, we degraded ourselves to what we
are now: clerks, functionaries, laborers, entertainers, processors of information." -

Re: Major Permit Modification and fee
Dear Mrs. Wilson:

I spoke with Toya Fields earlier this week concerning our permit modification request
and she recommended that we go ahead and request a Major Modification to reduce
monitoring frequencies and parameters. We feel this would be appropriate at this time
due to the decreased flow at our facility. Enclosed you will find the Major Mod. Fee, as
we would like to go ahead with this process. If anything further is needed, feel free to 71
contact me at 336-368-4041. ,�, sad' •' "f

Charles - Need some help advising Pilot Mountain. They are looking for ways to save money since
industry has left town (their pretreatment program is now inactive). The ORC called and asked about
changing their classification from a Grade III (3/week sampling frequency) to a Grade II (1/week
sampling). The permitted flow is 1.5 MGD. However, actual daily average flows are well below 0.3
MGD. If the town requested a new flow limit of 0.5 MGD, could they get 1/week monitoring? Is so,
what would they need to submit? Thanks, Mike.
