Notes:
1. The monthly average BOD5 and Total Suspended Solids concentrations shall not exceed 15%
of the respective influent value (85% removal).
2. The effluent daily average dissolved oxygen concentration shall not be less than 5.0 mg/L.
3. The facility shall report all effluent TRC values reported by a NC certified laboratory including
field certified. However, effluent values below 50 ug/ 1 will be treated as zero for compliance
purposes.
4. Chronic Toxicity (Ceriodaphnia) P/F at 37%; tests shall be conducted in March, June,
September and December [see condition A. (2) for further details]. Chronic toxicity sampling
shall coincide with metals sampling.
5. U: upstream at least 100 feet from the outfall. D: downstream from the outfall, 50 feet
upstream of the Pacolet River. Upstream and downstream monitoring shall be conducted
three times per week in June, July, August and September and once per week during the
other months of the year.
There shall be no discharge of floating solids or visible foam in other than trace
amounts.

Permit NC0021601
A. (2) CHRONIC TOXICITY 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 37%.
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 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 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 foIIowing 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. If reporting pass/fail results using the parameter code TGP3B,
DWQ Form AT-1 (original) is sent to the below address. If reporting Chronic Value results using the parameter code
THP3B, 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 Iater 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 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 Iast day of the month following the month of the
initial monitoring.

A. (3) EFFLUENT POLLUTANT SCAN
Ve
The Permittee shall perform an annual Effluent Pollutant Scan for all parameters listed in the attached table.
The analytical methods shall be in accordance with 40 CFR Part 136 and shall be sufficiently
sensitive to determine whether parameters are present in concentrations greater than applicable
standards and criteria. Samples shall represent seasonal variations. Unless otherwise indicated,
metals shall be analyzed as "total recoverable."

BACKGROUND
The Town of Tryon WWTP is a Class III facility with a permitted flow of 1.5 MGD. The permit was
originally issued on January 9, 2004 and expires on December 31, 2008. The Permittee submitted EPA
Form 2A on September 30, 2008 in order to request renewal of the permit.
Since Tryon only has one Significant Industrial User (SIU) has a modified pretreatment program with the
Division of Water Quality's Pretreatment Unit and will continue to implement this program in the new
permit term. The facility has not requested any changes to the permit.
Instream Monitoring, Verification of Existing Conditions and DMR Data Review
This facility discharges to Vaughn Creek in subbasin 03-08-06 of the Broad River Basin. Vaughn Creek
is currently classified as C waters and is not on the 2002-303(d) list.
Tryon monitors for dissolved oxygen (DO), temperature, conductivity and fecal coliform instream.
Review of the instream data indicated very little difference between upstream and downstream values for
dissolved oxygen and temperature, temperatures appears seasonally appropriate. Conductivity was
elevated downstream as compared to upstream.
REASONABLE POTENTIAL ANALYSIS:
Reasonable potential analysis was conducted for: As, Cl, Cr, Cd, Cu, F, Pb, Hg, Mo, Ni, Se, and Zn
(please see attached).
TOXICITY TESTING:
Type of Toxicity Test:
Existing Limit:
Recommended Limit:
Chronic P/F
001: Chronic P/F @ 37%
001: Chronic P/F @ 37%
Monitoring Schedule: March, June, September, December
The facility has been consistently passing its WET tests with one exception. Tryon failed its toxicity test
in December of 2006. Toxicity tests conducted after failures passed.
