There shall be no discharge of floating solids or visible foam in other than trace amounts.

Permit NC0044440
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 34 %.
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 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: NC DENR / DWQ / Environmental Sciences Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch 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 Branch 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.
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.

SUMMARY OF FACILITY INFORMATION AND WASTELOAD ALLOCATION
The City of Cherryville is requesting renewal of the Cherryville WWTP. The WWTP discharges into
Indian Creek, a class C stream. This facility is a major municipal treatment plant operating in Gaston
County that serves 5,000 people. City has a separate sewer collection system. The facility has permitted
flow of 2.0 MGD discharging into the Indian River. For the past 2 years annual average flow varied
within the range of 0.46-0.771 MGD. In the year 2001 the only significant industrial user has ceased
operation and WWTP is currently 100% domestic.
TOXICITY TESTING:
Current Requirement:
Proposed Requirement:
Chronic Toxicity P/F @ 34%; March, June, September, December
Chronic Toxicity P/F @ 34%; March, June, September, December
Toxicity Test Results : Facility has consistently passed the toxicity test, except for September 2002. Subsequent test
was a PASS.
REASONABLE POTENTIAL ANALYSIS:
The following parameters are monitored through the permit: CN, Cu, and Zn. Reasonable potential
analysis was conducted for: Cu, Zn, and CN (see attached).
COMPLIANCE SUMMARY:
DMRs have been reviewed for the period January 2001 through April 2004. Facility has a mixed
compliance record. During the review period, the following NOVs (notices of violation) have been
issued: 03/11/03 — CN, 03/03/03 - CN, 02/20/03 - CN, 12/03/02 - CN, 11/25/02 — WET failure,
11/20/02 - CN, 10/23/02 — pH and fecal, 06/06/02 — fecal. Facility has experienced most of the problems
during 2002-2003 time period. It has an excellent compliance record since April of 2002.
A compliance evaluation inspection conducted on January 13, 2005 found some minor problems with
self -monitoring and reporting. Other areas of compliance appeared to be satisfactory.
Cherryville WWTP Fact Sheet
NPDES Renewal
Page I

INSTREAM MONITORING:
Instream monitoring is required for temperature, dissolved oxygen, fecal coliform, and conductivity. An
analysis of DO, temperature and conductivity data indicated that the facility has an insignificant impact
on the water quality of the receiving stream.
PROPOSED CHANGES:
• Monitoring Frequencies: Monitoring for CN has been reduced to quarterly due to the elimination
of the limit. Monitoring for Cu and Zn have been reduced to quarterly based on the RPA.
• Limits: Based on the Reasonable Potential Analysis, limit for CN has been eliminated. A weekly
average limit for ammonia nitrogen and daily maxinium TRC limit have been added to the permit.
• Priority pollutant monitoring on an annual basis has been added to fulfill the permit application
requirement in the future.
ALL OTHER EXISTING PERMIT LIMITS AND MONITORING REQUIREMENTS WILL REMAIN
THE SAME.
PROPOSED SCHEDULE FOR PERMIT ISSUANCE:
Draft Permit to Public Notice: 05/25/2005 (est.)
Permit Scheduled to Issue: 07/06/2005 (est.)

PART IV - EVALUATION AND RECOMMENDATIONS
The City of Cherryville has applied for Permit renewal for the subject facility. The
pretreatment program has been inactivated since August 20, 2001, since there are no industries
discharging to the wastewater treatment plant.
The Cyanide has been reported to be below the detection limits for the past two years. It
is recommended that the Cyanide limits be deleted from the limits requirements. Also, the
source of Copper and Zinc has been eliminated since no industry is discharging to the WWTP;
therefore, Copper and Zinc should also be deleted from the monitoring requirements.
Page 3

It is requested that the TRC be limited since the monitored TRC average for the past year was
calculated to be 346 µg/1. Please note that a stream action level of 17 µg/1 has been established for
TRC to protect the receiving stream against chronic toxicity effects and 28 µg/1 has been set as the
maximum allowable effluent TRC concentration to protect against acute toxicity effects.
Pending review and approval by P&E, it is recommended that the permit be renewed to
include the changes noted above.
