terminated for any reason, the Permittee shall notify the Division in writing within five (5)
working days, unless the termination is initiated by the Division.

Permit NC00241 I
A. (3.) TOTAL PHOSPHORUS MONITORING
The Permittee shall calculate the seasonal mass loading of total phosphorus as the sum of monthly loadings,
according to the following equations:
(a) Monthly Mass Loading (lb/mo) = TP x Q x 8.34
where: TP = the average total phosphorus concentration (mg/L) of the
composite samples collected during the month
Q = the total volume of wastewater discharged during the month at
each outfall (MG/mo)
8.34 = conversion factor, from (mg/L x MG) to pounds
(b) Seasonal Mass Loading (lb/season) _ Y (Monthly Mass Loadings) for the season
The Permittee shall report the total phosphorus concentration for each sample and the monthly mass
loading in the appropriate self -monitoring report and the seasonal mass loading of total phosphorus in the
final self -monitoring report for the season.
A. (4.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Cenodaphnia dabia at an effluent concentration of 90.0%.
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 February, May, August and November. 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 Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621

Permit NC0024112
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 perrnittee 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.
A. (5.) NON -DETECTION REPORTING AND DETERMINATION OF COMPLIANCE
When pursuant to this permit a pollutant analysis is conducted using an approved analytical protocol with
the appropriate minimum detection level and a result of "non -detectable" or "below quantitation limit" is
obtained, the Pernuttee shall record that result as reported. For the purpose of determining compliance with
a permit limit for the pollutant, the numerical value of that individual analytical result shall be zero.

Permit NCO024112
A. (6.) EFFLUENT POLLUTANT SCAN
The Permittee shall perform an annual Effluent Pollutant Scan for all parameters listed in the attached table (using a sufficiently sensitive
detection level in accordance with 40 CFR Put 136). Samples shall represent seasonal variations. Unless otherwise indicated, metals shall be
analyzed as `total recoverable."

The City of Thomasville owns and operates a 4.0 MGD activated sludge wastewater treatment plant.
This facility is a major municipal treatment plant that serves 20,050 people. City has a separate
sewer collection system. For the past 2 years annual average flow varied within the range of 2.65-
3.31 MGD. Treatment consists of a comminutor, grit removal chamber, two primary clarifiers, two
roughing filters, three fine -bubble aeration basins, three secondary clarifiers, a 6 MG reaeration
lagoon, and chlorine disinfection. Waste sludge is anaerobically digested and then applied to land
under Non -Discharge Permit No. WQ0006050. The facility includes sand drying beds and a belt
filter press, but these are not in use.
The treatment plant currently operates at approximately 80% of its design capacity. The City
administers an industrial pretreatment program to control the discharge of industrial and commercial
wastes into its collection system and treatment works. Industrial sources include 9 Significant
Industrial Users.
The Thomasville WWTP discharges treated municipal wastewater to Hamby Creek, a Class C water
in the Yadkin -Pee Dee River basin. General water quality is rated as Poor and Fair in this portion of
the basin, due both to point source dischargers and nonpoint source runoff. Hamby Creek is
impaired due to elevated levels of fecal coliforrns. Currently, a TMDL is being developed to address
this issue. The facility is limited at the end of the pipe based on the WQ standard for fecal coliform,
and no changes are proposed with this renewal.

REASONABLE POTENTIAL ANALYSIS
The following parameters are monitored through the permit: Cd, Pb, Ni, CN, Cr, Cu, Ag, Zn, Hg.
The following parameters are monitored quarterly through the pretreatment program: As, Cd, Cr,
Cu, Pb, Hg, Mo, Ni, Se, Zn, CN, Ag, Sb. The permit will continue to require the City to implement
its pretreatment program
Reasonable potential analysis was conducted for: Ag, As, Cd, CN, Cu, Cr, Hg, Ni, Pb, Sc, and Zn.
(see attached).
TOXICITY TL'STING:
Type of Toxicity Test: Chronic P/F
Existing Limit: 001: Chronic P/F @ 90%
Recommended Limit: 001: Chronic P/F @ 90%
Monitoring Schedule: February, May, August, November
The facility has failed four WET tests since their last renewal and is currently under the Action Level
Policy (02/23/2004).
COMPLIANCE SUMMARY:
DMRs have been reviewed for the period January 2000 through September 2003. Facility has a bad
compliance record. During 2003, 12 NOVs (notices of violation) have been issued for violating
numerous parameters, including CN, Ni, BOD, DO, toxicity, pH, Cd, and Pb; during 2002, 10
NOVs were issued; during 2001, 8 NOVs were issued; during 2000, 9 NOVs were issued. Region
staff indicated that facility is working on the developing SOC language. It is suspected that
unauthorized dumping is the main cause of limit violations.
INSTREAM MONITORING:
Instream monitoring is required for temperature, dissolved oxygen, fecal coliform, conductivity,
total phosphorus, TKN, ammonia nitrogen, nitrate + nitrite nitrogen, and chlorophyll -a. An analysis
of DO, temperature and conductivity data showed that the facility might have some negative impact
on conductivity of the stream water (table is attached). Evidence does not suggest that facility has
any significant negative impact on dissolved oxygen and temperature.
PROPOSED CHANGES:
• Mentlenng Frequen,76: Weekly monitoring for chromium and selenium has been introduced
due to the implementation of the new permit limit.
• Lisnitr. Based on the Reasonable Potential Analysis, limits are being introduced for
chromium and selenium. In addition, weekly average limit for ammonia nitrogen, daily
maximum limit for total residual chlorine have been added to the permit. The daily maximum
limit for nickel is being increased to 94.1 µg/L.
• Priority pollutant monitoring on an annual basis has been added to fulfill the permit application
requirement in the future.

REGIONAL OFFICE COMMENT:
Regional office suspects that violations are the result of illegal dumping and is working with the city
to resolve the issue.

Hamby Creek WWTP NC 0024112 Permit Renewal Yadkin — Pee Dee
B.3. The Hamby Creek Wastewater Treatment Plant receives sewage from the City of
Thomasville via sanitary sewer and provides treatment before it is discharged to Hamby
Creek. Preliminary treatment at the plant consists of a manual barscreen, comminutor,
grit collector, grit pump, and grit washer. The comminutor grinds or shreds the large
materials entering the plant. The manual barscreen provides a bypass of the comminutor
for servicing and high flows. The grit collector, pump, and washer remove sand, cinders,
and gravel from the influent flow that could cause abrasion of units in the plant.
Primary treatment consists of the primary clarifiers which remove the settleable solids
from the influent and trickling filters using rock media. This helps to lower the BOD
loading on the plant's secondary treatment processes.
Secondary treatment consists of 6 activated sludge basins utilizing blowers for
oxygenation and three final clarifier units. Effluent from the clarifiers is pumped to a
polishing pond with three floating aerators. Disinfection of effluent from the polishing
pond is done by chlorine gas injection and flash mixing. Effluent then falls over two
short waterfalls and is discharged via a pipeline to the confluence of Hamby and North
Hamby Creeks.
Activated sludge from the bottom of the secondary clarifiers is pumped back and the flow
is split between the primary clarifiers and return sludge mixed with influent to the
aeration basin. Sludge is wasted from the primary clarifiers by pumping it to the
anaerobic digesters.
Sludge from the digesters is either liquid land applied, dried on drying beds, or belt
pressed for disposal via landfill.

Whole Effluent Toxicity (WET) Testing
Copper and Zinc Action Level Policy
NPDES Permit No. NCO024 t 12
City of Thomasville WWTP
Davidson County
Dear Mr. Bryant:
This is to inform you that a review of your toxicity self -monitoring report form for the month of
November 2003 indicates a violation of the toxicity limitation specified in your NPDES Permit. You
should undertake necessary actions to eliminate or reduce effluent toxicity to acceptable levels.
In addition, this correspondence contains important information on the Division's Copper and
Zinc Action Level Policy which is triggered by two or more toxicity limit violations that occur during
the toxicity testing calendar quarter specified by the toxicity testing special condition of your NPDES
Permit. Attachments addressing policy implementation and a copy of the Division's Toxicity Reduction
Guidance have been included with this Notice of Violation.
You should initiate follow-up toxicity testing upon a single WET test failure which occurs
during the toxicity testing calendar quarter.
Your facility is currently monitoring for copper and/or zinc and the data indicate that the levels
of copper/zinc in your effluent have the potential to cause an exceedance of the NC water quality action
level for this (these) parameter(s) in your receiving stream during low stream flow conditions. The
policy states that whenever a facility experiences two or more toxicity limit violations during a toxicity
testing calendar quarter, the NPDES Permit will be modified to include numeric limits for copper and/or
zinc UNLESS the permittee provides one or more of the following:
1. Instream measurements of dissolved metal during low flow conditions that demonstrate
compliance with the Action Level standard
2. A revision of the prospective permit limit using improved inputs that in concert with
existing or additional monitoring data demonstrates compliance with the Action Level
standard
3. Toxicity Identification Evaluation (TIE) results that definitively rule out copper and/or zinc
as causes of effluent toxicity
4. Demonstration by an alternative method approved by the Division and EPA that copper
and/or zinc is not the cause of toxicity

2
The Division has evaluated your copper and/or zinc monitoring data. The Division has also
developed a prospective NPDES permit limit based on your facility's instream waste concentration, the
copper and/or zinc action level criterion and a translator procedure. Based on this data your prospective
copper permit limit is 18 µg/L and your prospective zinc permit limit is 152 µg/L.
The permittee, upon experiencing two or more toxicity limit violations during a toxicity
testing calendar quarter must either provide DWQ with:
a) Written notification indicating acceptance of the prospective copper
and/or zinc permit limit. Notification is due within 30 days after the date of
the second WET Notice of Violation.
OR
b) Written notification indicating your choice of option(s) as noted on page
one of this correspondence. Notification is due within 30 days after the date
of the second WET Notice of Violation. DWQ approval of options 1-3
(previous page) is not necessary as the Division expects work to rule out
copper and/or zinc as causative effluent toxicants to begin immediately upon
the second WET permit limit violation.
Written notification (a or b above) shall be sent to:
North Carolina Division of Water Quality
Environmental Sciences Branch
Aquatic Toxicology Unit
1621 Mail Service Center
Raleigh. North Carolina 27699-1621
Please note that if you choose item b) above, you will be given nine months to submit
documentation that eliminates copper and/or zinc as causative effluent toxicants. Your final report
should be comprehensive and include all data used to support your conclusion(s). Should the data
indicate copper and/or zinc as the source of effluent toxicity or if the data are inconclusive as to copper
and/or zinc's role as a toxicity source, then the NPDES Permit will be reopened and the metal limits
specified above will be applied to the permit. The report is due nine months after the date of the second
WET Notice of Violation.
Three copies of the final report shall be submitted to:
North Carolina Division of Water Quality
Environmental Sciences Branch
Aquatic Toxicology Unit
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
You should consider submitting the above correspondence certified mail.
Failure to notify DWQ of your acceptance of a copper and/or zinc limit, failure to notify
DWQ of your option selection or failure to make acceptable demonstration to DWQ that copper
and/or zinc are not causative effluent toxicants within the stated time frames will result in
reopening of the NPDES Permit to include copper and/or zinc numeric limitations, as appropriate.
If the effluent is toxic, then we expect work to commence immediately with toxic effluent
samples. Failure to initiate work with toxic effluent samples during the study period is unacceptable and

3
will be considered a failure to make acceptable demonstration as cited above. We recommend a
minimum of three separate sampling events during the nine month period to definitively rule out copper
and/or zinc as causative effluent toxicants.
Please note that your actions to notify DWQ of prospective limit acceptance or to notify DWQ
of plan option(s) and subsequent submission of a plan are contingent upon two or more toxicity NPDES
permit limit violations occurring during a toxicity testing calendar quarter.
Also note that the WET limit will remain in your NPDES permit regardless of whether metals
are the source of effluent toxicity. The data resulting from your actions to disprove copper and/or zinc as
sources of effluent toxicity will determine whether NPDES Permit limits will be assigned for these
parameters. You are responsible for initiating actions to address these issues.
You may consider entering into a Special Order by Consent (SOC) with DWQ. A SOC provides
regulatory relief for specific NPDES permit limit violations and, if signed, will contain a requirement to
conduct a Toxicity Reduction Evaluation. The SOC will contain a compliance schedule, stipulated
penalties for failing to meet milestone activity dates and may contain upfront penalties to settle past
permit limit violations.
Additional information regarding the Division's copper and/or zinc action level policy can be
found at the following web site - http://www.esb.enr.state.nc.us. Click on the "Aquatic
Toxicology" Unit and go to the prompt "DOWNLOADS" located at the bottom of the page. This web
site also contains EPA's "Toxicity Reduction Evaluation Guidance for Municipal Wastewater Treatment

Evaluations.
