Subject: Issuance of NPDES Permit
NCO021181
Belmont WWTP
Gaston County
Dear Mr. Webb:
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).
This final permit contains no significant changes from the draft you were sent on November 9, 2005.
Please note that this facility will be subject to additional treatment requirements upon expansion
above 5 MGD. The Catawba Basinwide Water Quality Plan recommends that all new and expanding
discharges of oxygen consuming wastes to the lakes (including Lake Wylie) should be required to meet a
minimum of advanced treatment limits of 15 mg/L BOD5 and 4 mg/L NH3. In addition, upon future
expansion, this facility will be subject to the lake Wylie Nutrient Management Strategy, which requires
monthly average limits of 1 mg/L total phosphorus and 6 mg/L total nitrogen (summer only).
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 required.
If you have any questions concerning this permit, please contact Toya Fields at telephone
number [phone], extension 551.
Sincerely,
fdl� /arl W. Klimek, P.E.

SUPPLEMENT TO EFFLUENT LIMITATIONS
AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A (2). CHRONIC TOXICITY PERMIT LIMIT (QRTRLY) -
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 8%.
The permit holder shall perform at a minimum, uag rterly monitoring using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or
"North Carolina Phase 11 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 lI 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 H 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 Section
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.

Permit No. NCO021181
A. (3) EFFLUENT POLLUTANT SCAN
The permittee shall perform an annual Effluent Pollutant Scan for all parameters listed in the table below (in
accordance with 40 CFR Part 136). The annual effluent pollutant scan samples shall represent seasonal (summer,
winter, fall, spring) variations over the 5-year permit cycle. Unless otherwise indicated, metals shall be analyzed as
"total recoverable." Additionally, the method detection level and the minimum level shall be the most sensitive as
provided by the appropriate analytical procedure.

from Debra Watts, Groundwater Protection Unit.
➢ Add yearly PPA requirement
➢ Add TRC limit
2.0 Summary
The Belmont WWTP discharges to the mainstem of the Catawba River in Lake Wylie, which is
classified as a water supply (WS-IV, B CA). The submerged outfall structure is located 345 feet
from the shoreline, approximately 12 feet below the water surface. The discharge point falls
within the lake Wylie Nutrient management Strategy area, and therefore the facility would be
subject to nutrient limits upon expansion.
This facility has a STMP and will be required to continue implementing its pretreatment
program. There are no SIUs currently discharging to the WWTP and only one CIU (Spartan
Dyes)
3.0 Compliance Summary
DMR Data Review
DMR data was reviewed for the period of January 2002- August 2005. A summary of monthly
average effluent data is presented in the following table. Maximum monthly average flows are
currently at 47% capacity. The facility has violated its BOD, fecal coliform, TSS and pH limits
over the past permit cycle. Those violations will be discussed in the section on Compliance
History.

RPA Analysis
There were no monitoring requirements for metals in the facility's NPDES permit; therefore
RPAs were performed on data submitted as part of the LTMP. Analyses were performed for
arsenic, cadmium, chromium, copper, cyanide, lead, mercury, molybdenum, nickel, selenium,
silver, zinc. With the exception of copper and zinc, predicted maximum concentrations for all
parameters were below the allowable concentrations. Although levels of copper and zinc were
predicted above the allowable concentration, these are action level parameters' and data does not
show that they are having a toxic effect on the receiving stream.
WET Test Results
The Belmont WWTP has a chronic WET testing requirement at 8%. Since January 2001 they have
passed 19/20 tests administered. The single failure was in May 2004. No cause was determined.
Correspondence File Review/Compliance History
Between January 2002 and August 2005 the facility has incurred two permit violations for BOD
(one weekly average, one monthly average), four for fecal coliform (weekly geometric mean
exceedances), one TSS monthly average exceedance, and 12 pH violations (11 daily minimum
and one daily maximum). All violations were minor enough to receive NOVs except one fecal
coliform weekly geometric mean violation that proceeded to an enforcement case.

Toya,
Thanks for getting back with me so quickly. In answer to your questions:
/Just to clarify, they won't need to perform any groundwater monitoring? /Right. I
would recommend some language like "Groundwater monitoring is not required at this
time." We will not ask them to abandon the wells since we may want them to sample
for other purposes.
/Would you like to be copied on the draft permit? /Yes, that would be great.
Toya Fields wrote:
Thanks for writing Debra.
I can handle the change during the renewal, that won't be a problem. Just to
clarify, they won't need to perform any groundwater monitoring? Would you like
to be copied on the draft permit?

I have been working with your boss, Dave Goodrich, in addressing groundwater
monitoring wells on NPDES permits. The permit I have listed above,
NC0021181, City of Belmont, was originally listed as having 4 monitoring
wells (probably in their ATC).
I wrote a memo to Dave and he concurred (7/5/2005) that we need to close out
these wells. We (APS) were going to address this in a letter, but since you
are in the middle of your review of this permit, I was wondering if it would
be more expedient for you to address this when you issue the permit, for
example, in your cover letter or comments "groundwater monitoring is not
required at this time" -- this is basically for their clarification as to
whether or not they need to monitor.
If this is a problem, please let me know. Also, if you would like to
discuss, please call me at the number below. Thanks! djw

Dana- this sounds fine with me. They continue to pass their toxicity test, so copper is not really considered a problem,
and we'll have enough cyanide data to do the RPA.
Dana Folley wrote:
Hey, Tom, I was reviewing Belmont's LTMP and was looking at their NPDES permit to make sure all NPDES POCs
are properly addressed. I noticed that the fact sheet and cover page talked about "maintaining the LTMP monthly
sampling" for cyanide and copper and re-evaluating the data at the next renewal. The City does have monthly
effluent sampling for all LTMP POCs (including CN and cu), which is unusual. The City is interested in cutting this
back to the normal quarterly sampling frequency that is in our guidance and that most other POTWs do. I plan to
approve this for all other LTMP POCs, but wanted NPDES Unit concurrence before I approved quarterly effluent for
copper and cyanide. I looked at the DMRs beginning with 4/02 when the current permit became effective to see what
the effect of them cutting back would be, both on your RPA and our Headworks Analysis (HWA):
1. The coppers have been bouncing around in the 11 to 60 ug/l level, and the monthly sampling from 4/02 to
12/03 gives us 21 samples. If they cut back to quarterly for 2004, you'll still have at least 25 samples when the
renewal is done in early 2005. I'm also thinking this is plenty to do an RPA ... what are your thoughts? [HWA
isn't due til 2007, so I'll be happy with quarterly till then.]
2. The cyanides, unfortunately, are another matter altogether ... I discovered that they haven't been meeting the
LTMP required detection level of 0.01 mg/I since 10/02. So between 4/02 and 12/03, you have monthly data
with 2 detections @ 0.011 and 0.013 mg/l, 4 values @ <0.01 mg/1, and 15 values at 0.02 mg/1.. I've told the
POTW that they need to get this fixed pronto, beginning with seeing if the lab still has the January sample and
can re -run it at 0.01. (and the MRO may want to send them an NOV). I'm inclined to require them to continue
with the monthly for awhile at least, to make up for the LTMP violation. But since the HWA isn't due til early
2007, from my perspective I don't necessarily need lots more monthlys as we still have three years to get
enough good data. But you need to do the RPA in early 2005, so I propose I require the POTW to continue
with monthly cyanide through the end of 2004 so you'll have 12 data points with a good detection level, and
then let then go to quarterly in 2005. Would this be acceptable for your RPA needs? Note you also have the 6
good detection values between 4/02 and 9/02 if you want to use those, plus if you wanted, you could use the 15
<0.02's as one-half detection level.
Let me know!
