Subject: Issuance of NPDES Permit NCO020591
Third Creek WWTP
Iredell County
Division personnel have reviewed and approved your application for renewal of the subject permit. Accordingly, we are
forwarding the attached NPDES discharge permit. This permit is issued pursuant to the requirements of North Carolina General
Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency
dated May 9,1994 (or as subsequently amended).
The following changes were made to the final permit in response to your comment letter of December 19, 2000:
➢ The limits for Lead, Chromium, and Nickel have been deleted. Reasonable Potential Analyses indicated
that the maximum predicted levels for these parameters were less than the allowable concentrations.
Therefore, fin -its for these parameters are no longer necessary.
➢ Instream monitoring of Fecal Coliform and Conductivity has been deleted.
➢ . The daily max limit for Cadmium was revised from 12.8 to 15 µg/1 as per current Division policy.
➢ The daily max limit for Cyanide was revised from 51.6 to 22 µg/1 as per current Division policy.
➢ Monitoring for Total Nitrogen and Total Phosphorus has been changed to weekly. The results of this
additional monitoring will be used in the development of a nutrient management strategy for the Yadkin
River Basin.
➢ The limits for ammonia nitrogen were inadvertently changed in the draft permit. We apologize for this
mistake and have reinstated your previous limits.
If any parts,.measurement frequencies or sampling requirements contained in this permit are unacceptable to you, you
have the tight 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 (6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless such demand is
made, taus decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may require
modification or revocation and reissuance of the permit This permit does not affect the legal requirements to obtain other
permits which may be required by the Division of Water Quality or permits required by the Division of Land Resources, the
Coastal Area Management Act or any other Federal or Local governmental permit that may be required. If you have any
questions concerning this permit, please contact David Goodrich at telephone number [phone], extension 517.

Permit. N00020591 .
A. (2.) CHRONIC TOXICITY PERMIT LIMIT (Quarterly)
The effluerat discharge shall at no time exhibit observable inhibition of reproduction of significant mortality to
Cniodaphniui dubia at an effluent concentration of 39%.
The permits holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North
Carolina Geriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or
"North Camolina Phase II Chronic %X-1ole 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 saunpling 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
Emit, then multiple -concentration testing shall be performed at a minimum, in each of the two following months as
described inn "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, ewxposure regimes, and further statistical methods are specified in the "North Carolina.Phase 11 Chronic
\thole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition voll be entered on the Effluent Discharge
itlonitoring Form (11R-1) for the months in which tests wc*re perfoxrmed, using the.parameter code TGP3B for the
pass/fail results and THP3B for the Chronic Value. Additionally, D%t'Q Form AT-3 (original) is to be sent to the
following address:

days after tdic end of the reporting period for which the report is made.
Test data s1hall be complete, accurate, include all supporting chemical/physical measurements and all
concentratuon/response data, and be certified by laboratory supen-issor and 4RC 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 thecae be no discharge of flow from the facility during a month in which toxicity monitoring is required, the
permittee %ill 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 monthilyear 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 immmdiate follow-up testing to be completed no later than the last day of the month following the month of the initial

conversation Ms. Carol Rogers, Pretreatment Coordinator, had with Mr. Joe Corporone.

K1. Ammonia. We have a concern with the proposed ammonia limits. This is a
drastic reduction. No reason for this reduction was given. Mr. Corporone
advised Ms. Rogers that these limits appeared to be in error and that the old
limits would be reinstated. We would request the old limits be reinstated.
y�rr1 ' 2. Cadmium. We believe the weekly limit proposed for Cadmium under the
6-MGD permit to be too low to achieve compliance. We request a higher
limit.
tX3. Cyanide. The limit for Cyanide is too low. Mr. Corporone recaluulated
� t this and told Ms. Rogers an error had been made. After Mr. Corporone
L ' had a discussion with Mr. Dave Goodricb, Mr. Corporone informed Ms.

4. Alternative Analysis Evaluation: N/A
PART IV - EVALUATION AND RECOMMENDATIONS
The permittee, City of Statesville, has applied for permit renewal. The WWTP serves the
Third Creek basin of the city. The WWTP appears to be adequate to meet all existing effluent
limits and is well maintained and operated. The subject WWTP is a member of the Yadkin Pee -
Dee River Basin Association. As a member, all instream monitoring is conducted by the
association. However, influent and effluent sampling remains under the control of the WWTP
facility.
This office has received multiple complaints regarding the colored effluent from this
WWTP. Jeff Carty (ORC) stated that the color is primarily attributable to MoCaro Dyeing and
Finishing. MoCaro contributes approximately 500,000 gallons of wastewater per day to the plant
(25% of the total daily load). The effluent color varies from deep red to purple and noticeably
tints Third Creek for several miles downstream. However, there is very little public exposure
downstream as the stream is surrounded by farmland and undeveloped woodlands. Most of the
complaints have come from observations at road crossings. If quantitative color standards are
ever adopted, the effluent from this plant would need to be reviewed.
It is recommended that the NPDES permit be. renewed as requested.

Summary
The facility has requested a permit renewal with no modifications.
The following notes were taken during the review of the application package:
➢ Review of Basin Plan:
Fecal coliform levels in Third and Fourth Creeks are high upstream of
Statesville's dischargers, indicating that non -point source runoff
contamination is the probable source although several small facilities in the
subbasin show occasional violations.
The two largest of these major facilities are Statesville's third and Fourth
Creek WWTPs. No instream DO violations were reported by Statesville's
Fourth Creek WWTP in its self monitoring reports during 1992-1996. There
is, however, a measurable decrease in DO concentrations below the
discharge.
DWQ intends to develop NPS management strategies for this waterbody for
the second Yadkin -Pee Dee River Basin Plan. In addition, local efforts are
needed to develop a plan to reduce non -point source pollution.
➢ 303(d) List Review
Not reported on 303d List

FACT SHEET FOR NPDES PERMIT DEVELOPMENT
NPDES No. NCO020591
(Continued)
➢ Reasonable Potential Analysis:
A reasonable potential analysis was performed using the most recent DMR data.
The results of the analysis are attached to this document. In summary,
- Cadmium The maximum predicted concentration was determined to
be greater than the allowable concentration. Therefore, a limit of 5.2
µg/l was be included in the renewal.
- Cyanide The maximum predicted concentration was determined to
be greater than the allowable concentration. Therefore, a limit of
12.9 µg/1 was be included in the renewal.
Lead The maximum predicted concentration was determined to be
less than the allowable concentration. Therefore, no limit will be
included in the renewal.
- Nickel The maximum predicted concentration was determined to be
less than the allowable concentration. Therefore, no limit will be
included in the renewal.
- Selenium The maximum predicted concentration was determined to
be less than the allowable concentration. Therefore, no limit will be
included in the renewal.
- Chromium The maximum predicted concentration was determined
to be less than the allowable concentration. Therefore, no limit will
be included in the renewal.
- Copper Monitoring only for copper will be included in the permit.
This parameter has an action level of 7 µg/l.
- Mercury The maximum predicted concentration was determined to
be less than the allowable concentration. Therefore, no limit will be
included in the renewal. One hit was thrown out as error. The rest
were all below detection.
- Zinc Monitoring only for zinc will be included in the permit. This
parameter has an action level of 50 µg/l.
- Silver Monitoring only for zinc will be included in the permit. This
parameter has an action level of.56gg/1.
o .Otn
The facility joined the Yadkin Pee -Dee River Basin Association in June of
1998. Therefore, the established instream monitoring requirements will be
waived until the facility chooses to terminate its membership with the
association.

(Continued)
Facility appears to be operating within the constraints of their current permit
based on a review of past DMR data. Toxicity test results were pass for 1998
and January and April of 1999.
WLA Review:
The most recent WLA was prepared in April 1994. Limits were determined
to be water quality limited and instream monitoring was recommended for
DO, Fecal Coliform, Temperature, and Conductivity. In addition, the
following metals monitoring requirements were recommended: Cadmium
weekly average limit of 5.2 µg/l , Cyanide weekly average limit of 12.9 µg/l;
Nickel weekly average limit of 227.1 µg/l, lead weekly average limit of 64.5
µg/l, ,and Chromium weekly average limit of 129 µg/1. In addition,
monitoring was recommended for Selenium, Copper, Zinc, Chlorides,
MBA,S, and Silver.
➢ ATC Issued
Authorization was granted for the construction of two (2) belt presses with
feed pumps, polymer system and wash water pumps to replace the existing
dissolved air flotation (DAF) thickener. This ATC was issued January 30,
1997;
➢ Staff Report Review
Most 'recent staff report was prepared in February of 1999. The WWPT
appears to be adequate to meet all existing effluent limits and is well
maintained and operated. The subject WWTP is a member of the Yadkin -
Pee Dee River Basin Association. As a member, all instream monitoring is
conducted by the association. However, influent and effluent sampling
remains under the control of the WWTP facility.
Region recommends that the permit be renewed as requested.

Part III Permit No. NC0020591
G_ CHRONIC TOXICITY PASS/FAIL PERMTI' LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 39% (defined as treatment two in the North Carolina procedure document).
The permit holder shall perform quarterly monitoring using this procedure to establish compliance
with the permit condition. The first test will be performed after thirty days from the effective date
of this permit during the months of January, April, July, October. Effluent sampling for this
testing shall be performed at the NPDES permitted final effluent discharge below all treatment
processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter
code TGP3B. Additionally, DEM Form AT-1 (original) is to be sent to the following address:
Attention:
Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Environmental Management 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 and appropriate environmental controls, shall constitute an invalid test
and will require immediate retesting(within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.

Dear Mr. Goodrich:
On January 15, 1999, the City of Statesville submitted a renewal application for the
NPDES permits for our Third and Fourth Creek Plants. Please accept this letter as an
addendum to that application. We would like to present some additional information
which we feel is relevant, but was not included in our original application. This letter is
submitted at the urging of DENR representatives.

We are aware of the monitoring data review conducted by your unit during the
"Reasonable Potential Analysis." However, we would like to draw your attention to the
following results (Table 1). We would appreciate your consideration on reducing the
monitoring frequency or eliminating these parameters from the new permit.

We expect to see continued reductions in these and other metals discharges due to our
participation in EPA's Common Sense Initiative (CSI). The City of Statesville signed
onto this voluntary initiative as a participating municipality in March 1998. In this role,
our pretreatment industries have worked with DENR representatives (from the Divisions
of Water Quality, Waste Management, and Pollution Prevention) and the local metal
finishing community. Under the CSI, we grant regulatory flexibility in our local
pretreatment regulations in exchange for reductions in discharges from the local metal
finishers. To date we have four of eleven metal finishers signed on to this program and
hope to increase this number in the near future.
Should you have additional questions about specific monitoring data, please call me at
[phone]. If you have questions about our involvement in the Common Sense
Initiative please call Greg Newman or Terry Albrecht at the Division of Pollution
Prevention at [phone].
Thank you for your consideration.

Re: City of Statesville
Third Creek Wastewater Treatment Plant
NPDES Permit NC0020591
Permit Renewal
Dear Mr. Weaver:
With this letter and application, the City of Statesville requests renewal of its
Third Creek NPDES permit NC0020591. Please find enclosed the required completed
application and $400 renewal fee.
Per a conversation with Bethany Bolt on 1/14/99, we were advised to include a
copy of the old "additional wastewater characteristic sheet" as we did not receive a new
sheet in our application. These characteristics have not changed.
We request that the following process change be noted: In 1997, a new
dewatering facility was constructed. This facility contains two belt presses for sludge
dewatering.
If any additional information is needed, please contact Jeff Carty at
[phone].
Sincerely

Biosolids Management Plan
The City of Statesville owns and operates two wastewater treatment plants and a water treatment
plant which generate residuals. To manage these residuals, the biosolids management policy is
to process two-thirds of all residuals produced through the NViro process per Distribution Permit
number WQ0006245 and land apply the remaining one-third through a contract operation. The
contract for land application was signed on August 19, 1998 and the contractor is in the process
of obtaining the land application permits. The City also holds Land Application permit number
WQ0014543 which will only be used as a back-up method of residuals disposal. At this time, no
residuals have been land applied. All residuals are being processed through NViro.
The Third Creek WWTP processes an average wastewater flow of 2.0 million gallons per day.
After conventional processing through an activated sludge operation, sludge is aerobically
digested and then dewatered using a belt filter press. The press cake is transported to the Fourth
Creek Residuals Facility and is blended with biosolids from Fourth Creek and dewatered alum
sludge from the water plant. The blended material is stabilized using the NViro process per
Distribution Permit number WQ0006245.
After the contractor has obtained the land application permits, we will begin land applying one-
third of all residuals produced.
