Subject: Issuance of NPDES Permit Modification
Permit No. NC0036196
Clark Creek WWTP
Catawba County
Dear Mr. Sigmon:
Division personnel have reviewed and approved your request for modification 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 Statutes 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).
This revised permit includes the following changes from the City's current
permit:
Weekly average limit for arsenic has been deleted from this permit because this
parameter presented no reasonable potential to exceed the water quality standard
based on a statistical analysis of the effluent data. The City should continue to
monitor arsenic through the LTMP in the pretreatment program.
Please note that the weekly average and daily maximum limits for cyanide remain in the
permit because cyanide presented reasonable potential to exceed water quality standards
based on the statistical analysis of the effluent data.
If any parts, measurement frequencies or sampling requirements contained in this
permit are unacceptable to you, you have the right 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, this 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 l caro
required. Vatura

The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 56 %.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in
the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedures" 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:

AMENDED FACT SHEET FOR NPDES PERMIT DEVELOPMENT
NPDES Permit NC0036196
INTRODUCTION
The City of Newton Treatment Plant (WWTP), herein called Newton or the permittee,
requires a National Pollutant Discharge Elimination System (NPDES) permit to discharge
treated wastewater to the waters of the state. The permittee's 5-year NPDES permit expires at
midnight on July 31, 2010, and Newton has requested permit limits modification from the
Division of Water Quality. This Fact Sheet summarizes background information and rationale
used by the Division's NPDES Unit to determine permit limits and monitoring frequencies
revision.
FACILITY DESCRIPTION
Newton is a publicly owned treatment works (POTW) utilizing a Grade IV wastewater
treatment facility to treat domestic and industrial wastewater. The treatment system utilizes a
mechanical bar screen, two aerated grit chambers, two primary clarifiers, four aeration basins,
three secondary clarifiers, dual media filters, dual chlorination units, four gravity sludge
thickeners and post aeration. Table 1. Summarizes the receiving stream characteristics and
facility description.

The facility serves the City of Newton (-20000 people). Newton has active pre-treatment
program with a Long Term Monitoring Plan and has seven non -categorical significant
industrial users and two categorical industrial users. The facility has a existing 5.0 MGD
wastewater treatment facility, with expansion phase to 7.5 MGD.
BASINWIDE PLAN
The City of Newton — Clark Creek WWTP discharges into Clark Creek in the Catawba River
Basin. The stream classification of this segment of the Clark Creek is C. Clark Creek is listed
on North Carolina's 2006-303(d) list of impaired streams. That stream segment is impaired
for biological integrity. (North Carolina 303(d) List, 2006).
TOTAL RESIDUAL CHLORINE (TRC)
The permittee currently uses chlorine for disinfection. The Division has implemented TRC
policy to protect aquatic life in the waters of the State and has adopted aquatic life standard for
TRC. A TRC limit of 28 ug/1 and 26 ug/L should be continued in the permit for 5.0 MGD and
7.5 MGD respectively.
REASONABLE POTENTIAL ANALYSIS (RPA)
To establish a list of pollutants of concern (POCs), the Division examined Newton's two years of
pretreatment data, Discharge Monitoring Reports, and the basin plan. The Division then applied
the reasonable potential analysis to calculate a maximum predicted concentration for each POC.
Each maximum predicted concentration was then compared to the POC's freshwater
standard/criterion or allowable concentration considering dilution. If by this method, a POC
showed reasonable potential to exceed its standard or criterion, the Division included a limit in the
permit as a weekly average to protect the receiving stream against chronic toxicity impact, and as a
daily maximum against acute toxicity impact.
A reasonable potential analysis was performed on the following parameters: copper, cyanide,
and zinc. Results and data analysis are attached.
RPA RESULTS:
Based on the results of the Reasonable Potential Analysis:
• Limit and monitoring for arsenic should be deleted. Arsenic results had fifty-five
(55) reported values and all were below detection. No RPA was performed on
arsenic parameters.
• Limit and monitoring for cyanide should be continued in this permit. RPA
results showed the maximum predicted concentrations exceeding the allowable
concentration.
Fact Sheet
Renewal -- NPDES NC0036196
Page 2

• 2/month monitoring for copper should be continued in the permit. RPA results
showed the maximum predicted concentrations exceeding the allowable action level
concentration.
• No monitoring for zinc is added. This is because only four (4) data points were
used in the RPA and the facility have had excellent toxicity testing recording.
Monitoring will be continued in the LTMP program.

The permittee has passed all the seventeen WET tests from 2003 to 2007.
PROPOSED CHANGES
• Monitoring Frequencies:
• Weekly monitoring for arsenic has been deleted because this pollutant presented
no reasonable potential to exceed the water quality standards based on the
statistical analysis of the effluent data.
• 2/month monitoring for zinc has been added to 5.0 MGD phase since there was
reasonable potential to exceed action level standard.
• Limits:
• Weekly average limit for arsenic has been deleted because arsenic presented no
reasonable potential to exceed water quality standards.

To: <[e-mail]>
Mr. Agyeman Adu-Poku,
I wanted to confirm our conversation per your 7/18/07 letter concerning zinc monitoring requirements and also offer
additional information toward the City request to eliminate cyanide limits and monitoring from permit NC0036196 and also
request that copper monitoring be removed from the permit.
I contacted you 7/24/07 to discuss your proposal to implement effluent zinc monitoring. After we talked about action levels,
number of entries into the reasonable potential analysis (RPA) and City of Newton WWTP toxicity history you informed me
that the permit modification would not include effluent zinc monitoring. If I misunderstood please notify me.
Concerning the request to eliminate cyanide limits and monitoring you said the RPA indicated that the stream standard would
be violated. Some of the testing results from Pace Analytical used in the RPA are documented as flawed. The Division has
recognized these results as unreliable. I also have a copy of a client letter that attempts to explain the cyanide testing
problems. These extremely high results as documented by split sampling have to be removed from the RPA calculation.
Therefore the City requests that 10 of the 57 Pace Analytical results be stricken from RPA consideration and all of the
Meritech (72) results that happen to be below detection level be used in this determination. I have attached a summary of all
of the cyanide testing for your consideration.
As directed by the Division (March 16, 2006) the City of Newton staff has collected the required twelve months of effluent
total copper samples to request a permit modification to remove copper monitoring from permit NC0036196. I have attached

Mr. Sigmon:
Attached to this email is the fact sheet and the RPA data sheet. Because the City
requested for limit modification, I had to review all the pollutant of concern at the
facility and when the review was completed, zinc had to be added because it showed
reasonable potential to exceed action level standards.
I reviewed the data for cyanide and it also showed reasonable potential to exceed
water quality standards so I could not take it out as requested. I apologize that it
was not clear in the July 18 letter. Please review the attached documents and let me
know if you have any comments. Thanks,
Agyeman

Mr. Sigmon:
The draft permit should go out to public notice on 7/18 and if no adverse comment is
received, the final permit will be issued on 9/10 and becoming effective 10/1.
I have reviewed all the metals data in this permit, cyanide shown reasonable
potential to exceed water quality standard so cyanide monitoring and limit cannot be
eliminated. Let me know if you have any more questions.
Thanks,

Mr. Agyeman,
I received and appreciate your phone message yesterday concerning the status of
the City of Newton request to eliminate arsenic from permit NC0036196 that was
received by the Division on May 22, 2007. You said that removing arsenic
monitoring and limitations from the permit is a major permit modification and
requires "public notice". When can the City expect a permit change to actually be
in place so that we can stop the presently required arsenic testing?
Additionally, this office has submitted (07/10/07) a request to eliminate cyanide
monitoring and limitations. Is there anything I can do or anyone I can contact to
expedite the processes of these requests? Any help you can provide would be
greatly appreciated.
Thanks,
Danny

Ms. Sullins:
As directed by the Division (March 16, 2006) the City of Newton WWTP staff has
collected more than the required twelve months of cyanide samples to request a permit
modification concerning cyanide monitoring. Unfortunately the lab used until March
2007 (Pace Analytical) appears to not have been the lab of choice. As you can see from
the attached cyanide reports there were seven hits from March 2006 until March 2007
when the hits appeared very high. That was when we started using Meritech Labs along
side Pace (yellow highlight). The comparison testing revealed a significant test result
difference that indicated a definite Pace lab testing problem. This testing problem
explained any previous hits because the remaining 68 daily effluent cyanide tests
conducted by Meritech were all below detection limits.
These daily effluent cyanide results of less than detectable are significant because of the
accompanying influent cyanide testing and resulting removal rate. As you can see the
influent cyanide results ranged from <5 ug/L to a high of 168 ug/L on 5 / 1 / 07 by
Meritech and the corresponding effluent levels remained at below detection limits. The
daily effluent cyanide tests (67) performed by Meritech were all below detection limits
proving beyond any doubt there is no reason for weekly cyanide monitoring or
limitations in the NC0036196 permit.
The City of Newton again (12 / 21 / 2005) formally requests that cyanide monitoring and
limitations be eliminated from permit NC0036196. The present Long Term Monitoring
Plan (LTMP) will continue to include cyanide testing at the WWTP influent, primary
clarifiers, aeration basins, effluent, significant industrial uscrs and sludge haulers.
This office would appreciate your earliest response. If you have any questions please do
not hesitate to contact me at 828.695.4346 or 828.217.4427.

Subject: Request to remove effluent arsenic monitoring and limitations from the City of
Newton WWTP permit NC0036196
Mr. Klimek:
As directed by the Division (March 16, 2006) the City of Newton WWTP staff has
collected more than the required twelve months of arsenic samples to request a permit
modification. The attached fifty five test results were all below detection levels. Given
that there has been no detectable level of arsenic in the effluent discharge for over one
year the City of Newton WWTP again (12/21/2005) formally requests that effluent
arsenic monitoring and limitations be eliminated from permit NC0036196. The present
Long Term Monitoring Plan (LTMP) continues to include arsenic testing at the WWTP
influent, primary clarifier, aeration basin and effluent on a quarterly basis. The LTMP
also requires arsenic testing on the significant industrial users and sludge haulers
annually.
This office would appreciate your earliest response. If you have any questions please do
not hesitate to contact me at 828.695.4346.
Respectfully Yours,
