Subject: FINAL -- NPDES Permit No. NC0081370
Claremont McLin Creek WWTP
End of NCSR 1728
Catawba County
Dear Mr. McGinnis:
According to your renewal request, received January 4, 2000, the Division of Water Quality
(the Division) hereby transmits your final NPDES Permit.
Please note that the Division is concerned about a catch basin located in the sludge handling
area. This basin has potential to capture and drain spilled sludge directly to McLin Creek.
Therefore, as a Special Condition to this permit, the permittee shall evaluate options to prevent
potential environmental impact, and discuss these options, conclusions, and recommendations in a
report. Please submit this report to the Division within six months of the effective date of this
permit [See Special Condition A. (3.)].
As part of permit renewal, the Division conducted EPA -required Reasonable Potential
Analysis (RPA) on this facility's effluent data to determine the "reasonable potential" for
identified metals and toxicants to exceed North Carolina Water Quality Stream Standards. Due to
the permittee's failure to conduct the required pretreatment monitoring (a permit violation), data
for seven (7) parameters of concern were not available for this analysis. The permittee is hereby
reminded that pretreatment sampling is mandatory, including that appropriate to monitor
influent diverted from Claremont South WWTP. Please include all pre-treatment analytical
results in monthly Discharge Monitoring Reports. Parameters include, but may not be limited to,
arsenic, cyanide, fluoride, mercury, molybdenum, selenium, and silver.
Considering the pervious permit, various changes have been implemented.
Monitoring Frequency Changes:
• Based on "reasonable potential" to exceed Water Quality Stream Standards, monitoring
shall continue for copper and zinc in this facility's effluent, however the frequency for
these two parameters shall be decreased from 2/Month to Monthly, in keeping with
Division permitting guidance for Class II facilities.

Deleting from Permit:
• Receiving -stream Conductivity and Fecal Coliform -- Based on existing stream
conditions and revised policy, the permittee shall no longer be required to monitor
receiving -stream conductivity or fecal coliform bacteria.
• Based on "reasonable potential," the permittee is no longer required to perform effluent
monitoring for oil and grease, cadmium, chromium, lead, or nickel. The permittee
shall continue to monitor these parameters under the pretreatment modified Long Term
Management Plan.
Although other parameters and monitoring requirements remain unchanged, please note
that the Division has reorganized the table under Effluent Limitations and Monitoring
Requirements by "Sample Location" to facilitate operator use.
If any parts, measurement frequencies, or sampling requirements contained in this permit
are unacceptable, you have the right to an adjudicatory hearing upon written request within thirty
(30) days after receiving this letter. Your 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 a demand is made, this permit shall be final and binding.
Please notice that this permit is not transferable except after notifying the Division of Water
Quality. The Division may require modification or revocation and re -issuance of this permit.
This permit does not affect the legal requirements to obtain other permits required by the
Division of Water Quality, the Division of Land Resources, the Coastal Area Management Act, or
other federal or local governments.
If you have questions, or if we can be of further service, please call Joe Corporon at (919) 733-

SPECIAL CONDITIONS
A. (2.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaplznia dubia at an effluent concentration of 9%.
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 January, April, July, and October. 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:
Environmental Sciences Branch
North Carolina Division of
Water Quality
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.

A. (3.) MITIGATION OF CATCH BASIN NEAR THE SLUDGE -HANDING AREA
The Division noted a catch basin within the sludge handling area with potential to collect spilled sludge and drain it
directly to McLin Creek. Therefore, the permittee shall submit a report evaluating potential sludge -loss preventative
options including conclusions and recommendations. The permittee shall submit said report within six months of the
effective date of this permit.
Following the Division's review of the permittee's report, the Division may reopen this permit to evaluate the need for
remedial action regarding the potential for loss of sludge and impact to McLin Creek.

Claremont's McLin Creek WWTP began operation officially with its first permit effective on June
26, 1995. This permit expired on June 30, 2000 and the Division received prompt documentation to
renew (Short Form A) on January 4, 2000.1'4
Waste Load Allocation (WLA). The Division prepared the last WLA in January 1995 and
developed effluent limits and monitoring considering an in -stream waste concentration (IWC) of 9 %.
The Division judges these limits and monitoring requirements to be appropriate for this renewal with
the exception of the additions and deletions listed below (see PERMITTING APPROACH SUMMARY).
Verifying Existing Stream Conditions. This facility discharges to McLin Creeks'$, a Class C stream
within the Catawba River Basins. McLin Creek is not listed as an "impaired" waterbody [not 303(d)
listed]6.
COMPLIANCE REVIEW
Pretreatment Compliance. A modified pretreatment program or Short Term Monitoring Plan has
been approved 2. However, this facility is delinquent in its sampling compliance. The WWTP
contractor (Water Tech) "...was not clear on sampling duties at takeover..." therefore some data have
not been collected for the past three years.8 The necessary Reasonable Potential Analysis (RPA)
required at renewal is therefore limited to permit -required parameters only. This will generate a
Notice of Violation.
Notices of Violation (NOVs). Pretreatment will issue a Notice of Violation (NOV) in January 2001
for failure to administer pretreatment monitoring. The Division has issued no other NOVs for this
facility within the last two years.
Whole Effluent Toxicity (WET) Test. Quarterly monitoring results for Whole Effluent Toxicity
(WET) testing indicates "pass" for the last 25 quarters (January 1996 through November 2000). 9,10
DMR Instream and Effluent Data Review. The Division reviewed over 32 months (1998 through
September 2000) of Discharge Monitoring Reports (DMRs). Reports appear regular, thorough, and
complete. Total flow for this time period averages about 0.180 MGD, increasing slightly during the
year 2000 to about 0.200 MGD (or about 66 % of permitted capacity).'°
Effluent Chlorine. This facility's Total Residual Chlorine (TRC) discharge is currently limited to 28
µg/L and its processes include dechlorination.4 Based on 34 months of data (1998 through October
2000), effluent concentrations have been consistently reported as <20 µg/L TRC and are therefore in
compliance with the permit".
Instream Dissolved Oxygen and Temperature. Instream dissolved oxygen (DO) and temperature data
appear reasonable and seasonally appropriate. Dissolved oxygen values are well above and
consistently compliant with the Stream Standard minimum of 5 mg/Llo
Instream Fecal Coliform. Weekly fecal coliform counts appear similar when comparing upstream to
downstream data. Counts range on any given day from 72 to 920 colonies per 100 ml1o. However, the
Division found proportionally similar values upstream and downstream suggesting little or no

correlation to the facility's discharge. Occasionally system effluent concentrations indicate single -day
levels of 140 colonies per 100 ml, but monthly averages consistently total less than 5 per 100 m11°
Based on these findings and the relatively high dilution of the receiving stream (IWC 9%), the
Division finds no reason to continue instream (upstream and downstream) fecal coliform sampling,
and recommends that it be discontinued.
Reasonable Potential Analysis (RPA). The Division conducted EPA -recommended RPA analyses
on 32 months of data10 to determine the "reasonable potential" for identified toxicants to exceed
Water Quality Standards. The Division compiled seven (7) parameters of concern listed in the
previous permit10 including oil and grease (O&G), cadmium (Cd), chromium (Cr), copper (Cu), lead
(Pb), nickel (Ni), and zinc (Zn). Due to the permittee's non-compliance to required pretreatment
sampling, there are no data available for RPA of arsenic (As), cyanide (Cy), fluoride (F1), mercury
(Hg), molybdenum (mo), selenium (Se), or silver (Ag).
Of the seven parameters analyzed, results suggest no "reasonable potential" for O&G, Cd, Cr, Pb, or
Ni to exceed Water Quality Standards. Because these parameters are monitored under the modified
Long Term Monitoring Plan (LTMP), and because there is no reasonable potential, these parameters
will be deleted from the permit.
Lastly, data suggest that there is "reasonable potential" for state action -level parameters Cu and Zn.
Because Cu and Zn have North Carolina State Action Levels only, they are to be monitored only
and not limited. These parameters have been monitored 2/month4, however in keeping with revised
facility Class II requirements and current policy, the Division hereby reduces the monitoring
frequency to monthly.
CORRESPONDENCE
Staff Report. Mooresville Regional Office (MRO) prepared a Staff Report dated May 22, 2000.
MRO staff found the facility "...in good operational condition..." and recommended "...that this
permit be renewed...." However, the MRO noted a catch basin in proximity to the sludge -loading
area plumbed to discharge directly to McLin Creek. The MRO recommended that this catch basin
be removed from this location to prevent potential unauthorized sludge discharges to McLin Creek.2
Therefore, a Special Condition will be added to the permit requiring mitigation within one year of the
effective date.
PERMITTING APPROACH SUMMARY
Special Condition A.(3.) requires a report concerning the potential for sludge to be lost into the catch
basin located at the sludge -handling area. The report is due within six months of the permit effective
date.

Previous Requirements: Dissolved Oxygen, Fecal Coliform, Temperature, Conductivity4.

Joe,
Today I received a call from Mr. Tony Gragg, Town of Claremont. He
reported that the Short Term Monitoring Plan sampling regime has not
been adhered to since the Water Tech Company has taken responsibility
for the WWTP for the Town of Claremont. I informed him that this news
requires me to issue a Notice of Violation for failing to administer the
Pretreatment Program Properly.
Mr. Gragg reports that all data that has been reported on Daily
Monitoring Reports is all of the data the POTW Staff has collected. I
am returning the PIRF Form to you with an attachment of this e-mail so
you will know the Pretreatment Unit has made an attempt to find you
useful information.
Effective immediately Mr. Gragg will resume the STMP Sampling as
required with one sample per quarter for the first half of year 2001,
and then monthly sampling starting in June for 12 months to gather data
for the Headworks Analysis due in July of 2002.

Dear Mr. McGinnis:
The Pretreatment Unit of the Division of Water Quality has received a request for the Short Term
Monitoring Plan (STMP) Data from the McLin Wastewater Treatment Plant. This request was made
by Mr. Joe Corporon of the NPDES Unit. I realize that you report to the Division on Daily
Monitoring Reports. Some Publicly Owned Treatment Works (POTW) do not always report all of
their STMP data. Please verify that your organization is reporting all of the STMP data and inform .
me if this is being done.
If the Town of Claremont maintains an electronic version of the STMP data, please send me at a
minimum the past two years. The data in an electronic format will greatly aid the NPDES Unit. You
can send the data by disk or e-mail.
Thank you for your continued cooperation with the Pretreatment Program. If you have any questions
or comments, please contact me at [phone] extension 580 ([e-mail]) or Tom
S. Poe, Supervisor of the Pretreatment Unit extension 522 ([e-mail]).

Subject: NPDES Permit Issuance
Permit No. NC0081370
McLin Creek WWTP
Catawba County
In accordance with the application for a discharge permit, the Division is forwarding herewith the
subject NPDES 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 US Environmental
Protection Agency dated December 6, 1983.
On April 28, 1995, the Division received a letter from Mr. Miles Champion commenting on the
subject permit. The Town of Claremont may expand the treatment plant in the future; however, the
Division cannot comment on expansion until the speculative limits are complete. The Division has made
the following changes in the final permit:
The supplement sheet has been changed to reflect a vortex degritter instead of aerated degritters.
Winter limits for BOD5 and NH3-N have been added to the permit
The Chronic Toxicity monitoring will be collected on a grab sample.
The metals monitoring requirements have been re -calculated using data that was not available when
the Division received the renewal application in January 1995. The Division has considered the
recent headworks analysis and additional DMR data to revise the monitoring. Copper and Zinc
monitoring will remain in the permit because the concentration of these metals may exceed the action
levels for the receiving stream. Monitoring for Cadmium, Chromium, Nickel, and Lead shall be
conducted quarterly to track potential sources of toxicity.
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, Post Office Drawer 27447, Raleigh, North Carolina 27611-7447. Unless such demand is
made, this decision shall be final and binding.
Please take notice this permit is not transferable. Part II, E.4. addresses the requirements to be
followed in case of change in ownership or control of this discharge.

G. CHRONIC TOXICITY PASS/FAIL PERMIT 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 9 % (defined as treatment two in the North Carolina procedure document).
The permit holder shall perform guarte* 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, and 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.

Re: NPDES Permit No. NC0081370
McLin Creek WWTP
Claremont, North Carolina
Catawba County
Dear Mr. Goodrich:
The City of Claremont has reviewed the subject draft NPDES permit
and hereby make the following comments:
1. Public Notice, last paragraph:
Please clarify the statement regarding the affect on future.:
effluent limitations. The City of Claremont intends to file "•
an NPDES permit application within the next year for expansion--'
of the McLin Creek facility for an additional flow of 0.3'
million gallons per day (MGD). Long range plans are o
continue expanding the plant as necessary to accommodate
future growth in Claremont. The plant site contains
approximately 14.7 acres which allows the facility toexparid
by 3 or 4 MGD. r-
Additionally, the City is seriously considering the
abandonment of the North WWTP (permit no. NC0032662 and
pumping all of the wastewater generated in the northern sector
of the City to the McLin Creek facility to reduce operate'ig
cost. Therefore, the time table for expansion of the McLin
Creek facility would be accelerated.
Claremont is also considering the abandonment of the South
WWTP (permit no. NC0026549) which is not operating at this
time. How would this affect future expansions of the McLin
Creek facility?
The City will request speculative discharge limits for
expansion of the McLin Creek WWTP from 0.3 MGD to 0.6 MGD
within the next two days and include the above mentioned
information.

2. Supplement to Permit Cover Sheet, paragraph 1:
"Aerated de-gritters" should be changed to "vortex de-
gritter".
3. Effluent Limitations and Monitoring Requirements:
a. Why were the winter effluent limits of 16 mg/1 BOD and
4.0 mg/1 Ammonia-N deleted from the permit?
b. Why were six metals (cadmium, chromium, copper, lead
nickel and zinc) added to the monitoring requirements
with cadmium having a daily maximum of 23.5 ug/1?
c. During a recent site visit by the Division of
Environmental Management, Inspection Unit personnel
indicated that the Chronic Toxicity sample type should be
grab instead of composite since the plant discharge is an
intermittent flow (batch reactor). Please clarify the
sample type.
We appreciate your response in these matters at your earliest
convenience.

TO: Dave
FROM: Jay Lucas
SUBJECT: Claremont-McLin Creek WWTP, NC0081370
DATE: June 14, 1995
After running your spreadsheet, I found Copper and Zinc to be the only
metals of concern (if I'm interpreting it correctly). When Farrell ran the
spreadsheet, he only had about five months of data from the DMRs. I was
able to use more DMR data plus the headworks analysis.
I eliminated all metals monitoring from the effluent sheet except Copper 0
and Zinc and included some other minor changes outlined in the cover
letter.
-;
"'7
4Ca
I talked to Miles Champion, their engineer, and he said the McLin Creek ti' =n
WWTP was put in operation on July 11, 1994. The South WWTP had all Ti
flow diverted to it immediately. The town plans to remove the North
WWTP in about 18 months.

Response to Comments to DRAFT NPDES Permit
A wasteload allocation was completed for this facility in March, 1995. A letter questioning the various
Permit requirements was sent in April, 1995. This memorandum represents the Instream Assessment
Unit response.
Comment #3 Effluent Limitations and Monitoring Requirements
a. "Why were the winter effluent limits of 16 mg/I BOD and 4.0 mg/I Ammonia-N deleted from this
permit ?"
Omission of the winter BOD and NH3-N was my fault and should have been included in the
permit. I request that winter limits of 16.0 mg/l BOD and 4.0 mg/l NH3-N be added to this permit.
b. "Why were six metals (cadmium, chromium, copper, lead, nickel, and zinc) added to the
monitoring requirements with cadmium having a daily maximum of 23.5 µg/I ?" 9it
These requirements were recommended based on the McLin plant accepting waste from the 1.8
Claremont - South WWTP [NC0026549]. The Claremont - South plant had high concentrations ,-/x,
of these metals in their effluent. Therefore, the potential for the McLin plant to have the same J?<
difficulties with these metals was unknown and required monitoring data to verify that
compliance with these standards would be consistently achieved. .:a- ›+
Second, the monitoring required by the Pretreatment Modified Monitoring Plan will not prdVide
enough data to assess these toxics; hence the need to require monitoring in the NPDES
permit. 117
The limit for cadmium was based on both the high concentrations reported from the Claremont -
South plant and an accompanying recommendation by the Mooresville Region to require a limit.
Please let the facility know that we will be happy aless th ata after twelve consecutive
months of monitoring, (i.e. one years worth, sta#r*�) and between 8 12 data
points are recorded for each parameter to be assessed. If the McLin plant decides to pursue
this option, the data should reflect treatment which includes the connected South plant.
Please let us know if we can be of more assistance.
