Subject: NPDES Permit Issuance
Permit No. NCO021181
Belmont WWTP
Gaston County
Dear Mr. Waiters:
Division staff have reviewed and approved your application for an NPDES discharge permit.
Accordingly, the Division is forwarding 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 U.S. Environmental Protection
Agency dated May 9, 1994 (or as subsequently amended).
The following items appear in this FINAL permit:
• Addition of a weekly average BOD5 effluent limit of 45.0 mg/l. The previous permit
contained a monthly average limit but incorrectly left out the weekly average limit.
• Deletion of the draft cyanide limit, which was proposed in the draft permit based on 2000
effluent data. Subsequently, the permittee submitted the full data set for 2001 which
showed no detections of cyanide (n=12; all < 10 ug/1) and requested deletion of the proposed
limit. The deletion is consistent with NPDES permitting policy. Effluent cyanide
monitoring will continue on a monthly basis as part of the Pretreatment LIMP, and cyanide
data will be re-evaluated during the next permit renewal. The facility should continue to
evaluate the monthly data, to ensure that cyanide is not a pollutant of concern.
The permit expiration date has been changed to 2/28/05.
Please note that the Division's NPDES Compliance Unit is separately evaluating the request
for a waiver from 15A NCAC 2H.0124 (4), which requires 7-day, 24-hour continuous
staffing for facilities with design capacity > 5 MGD. The Division understands that the
facility was investigating the cost of telemetry equipment.
Finally, 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/1
BOD5 and 4 mg/1 NH3-N. 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/1 total phosphorus and 6 mg/1 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 a demand is made, this permit shall be final and binding.

SUPPLEMENT TO EFFLUENT LnOTATIONS
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, guarterlu monitoring using test procedures outlined in the
"North Carolina Cedodaphnia 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, DWg Form AT-3
(original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of Water (duality
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.

PROJECT NOTES
Summary
• This is a permit renewal for a 5.0 MGD major municipal activated sludge WWTP serving a
population of 9500. Average daily industrial flow averaged 1.5 MGD, and the renewal
application reported 3 SIUs (all textile yarn dyers) discharging to the POTW. Sludge is land -
applied according to permit WQ0003281. The facility has been discharging since 1970.
• In the early 1990's the facility relocated its outfall pipe to the main stem Catawba River
(Lake Wylie), which is classified as water supply (WS-IV, B CA) at the discharge location.
The submerged outfall structure is located 345-feet from shoreline, at approximately 12-feet
below water surface. The receiving stream is not listed in the 2000 303(d) list of impaired
waterbodies. The discharge point falls within the Lake Wylie Nutrient Management Strategy
area, and therefore the facility will be subject to nutrient limitations upon expansion.
Permit Development
• Application. The previous permit expired 8/31 /01. The facility's renewal application
(Standard Form A) was received by the Division on 2/ 16/01.
• anide. Based on reasonable potential analysis, the 2000 DMR data indicated a potential
for the effluent to exceed the allowable chronic cyanide concentration (66 ug/1) and the
allowable acute concentration (22 ug/1). On 9/21 /00, the facility reported an effluent
concentration of 73 ug/1 and a concentration of 140 ug/1 in the west aeration basin. In
November 1999, the facility reported an influent concentration of 140 ug/1 and an effluent
concentration of 58 ug/1. Effuent data for 2001 (through August) has been below the
detection limit (<10 ug/1). The facility may request removal of the draft cyanide limit if
data for 12-months shows effluent concentrations below the detection limit. [REVISION: all
effluent data for 2001 (n=12) was < 10 ug/l, and the limit was deleted in the final permit.
Monthly monitoring is maintained in the Pretreatment LTMP1.
• Color. The facility's effluent is colored due to textile waste, however no instream aesthetic
impact is evident since the outfall is submerged and located >300-feet offshore. Therefore,
no color monitoring is recommended.
• Metals. Metals are analyzed monthly in effluent under the Pretreatment Long Term
Monitoring Plan. Copper was the only metal to show reasonable potential, but per the
Action Level Policy no limit is needed since the facility has been compliant with its chronic
toxicity test. Maintain monthly monitoring of metals under the Pretreatment LTMP.
• 24/7 Staffing Waiver Request. The facility is currently permitted for 5 MGD. At permit
renewal the facility requested a phased limit of 4 MGD be added, due to the recent loss of
Page 2
Version: February 22, 2002

NPDES PERMIT FACT SHEET City of Belmont
` Page 3 NPDES No. NCO021181
several major water users and the resultant decrease in average monthly flow to only 1.6-
2.5 MGD. Since the facility's main concern was the additional cost burden of 24-hour/7-
day staffing requirement for > 5 MGD facilities per 15A NCAC 2H.0124, the facility is now
requesting a waiver from the 24/7 staffing requirement. This waiver request is under
review by the NPDES Compliance Unit.
• Downstream Station. The facility's DMRs state the downstream monitoring station at 100-
feet below the outfall pipe, while the previous permit required 1-mile downstream
monitoring. The permittee stated that the monitoring has been at 1-mile below the outfall,
and the DMR will be corrected.
• Future Expansion. Note that upon expansion beyond 5 MGD, the facility will be subject to
the Lake Wylie Nutrient Management Strategy (1 mg/1 TP and 6 mg/1 TN summer). The
facility would also be subject to the Catawba Lakes Strategy, which requires the facility to
meet a minimum of advanced treatment limits (15 mg/1 BOD5 and 4 mg/I NH3-N). Based
on instream data showing low instream DO above the discharge (see below), more stringent
effluent limits would likely be required upon expansion.
• Water Quality Limited Parameters: cyanide in draft permit [REVISION: no parameters are
WQ-limited in final permit].
DMR Data.
• Effluent Physical/Chemical Data. For the period 1/01-8/01, the following range of monthly
average values were reported: 1.5-2.5 MGD [flow]; 2.8-11 mg/1 [BOD]; 0.2-3.1 mg/1 [NH3];
14-21 mg/1 [TSS]; 7-45 orgs/ 100m1 [fecal]; 2-14 mg/I [TN]; and 2-20 mg/1 [TP]. Daily
maximum TRC concentrations ranged up to 600-700 ug/l.
• Effluent Toxicity Data. The facility has passed 19 of 20 quarterly chronic toxicity tests
conducted between 1997-2001. The test is conducted at an effluent concentration of 8%.
• Instream Data. For 2000/01 period, the facility reported instream monitoring data at an
upstream and downstream station. Generally there were no instream trends noted for DO,
fecal coliforms, or conductivity between stations. Instream DO values were generally above
the WQS (5 mg/1) in summer 2001, but Summer 2000 data shows several values <5 mg/l,
particularly at the upstream station. For Summer 2001, there does not appear to be any
instream exceedance of the fecal coliform WQS.
• Compliance Data. There were no compliance enforcement assessments for this facility
between 1 /94-3/00. A civil penalty of $983 was assessed for May 2000 for monitoring
violations, and a Notice of Violation was sent for a chronic toxicity test failure reported in
August 2000.
Wasteload Allocation.
• The last WLA was conducted in 1996.
Mooresville Region Data.
• The MRO submitted a staff report dated 5/23/01 for this permit renewal. The staff report
states there are no water intakes for several miles below the discharge point. The report
notes there is color in the effluent. However, since the effluent is discharged below the
surface and >300-feet offshore, no color plume is evident.
• The MRO conducted a Compliance Evaluation Inspection on 10/24/00. The MRO reported
that the WWTP operation and maintenance is commendable, and a comprehensive process
control program is used.
Miscellaneous Data.
• The city reported 6 sewer line spills totaling 68,000 gallons during calendar year 2000.

PROJECT NOTES
Summary
• This is a permit renewal for a 5.0 MGD major municipal activated sludge WWTP serving a
population of 9500. Average daily industrial flow averaged 1.5 MGD, and the renewal
application reported 3 SIUs (all textile yarn dyers) discharging to the POTW. Sludge is land -
applied according to permit WQ0003281. The facility has been discharging since 1970.
• In the early 1990's the facility relocated its outfall pipe to the main stem Catawba River
(Lake Wylie), which is classified as water supply (WS-IV, B CA) at the discharge location.
The submerged outfall structure is located 345-feet from shoreline, at approximately 12-feet
below water surface. The receiving stream is not listed in the 2000 303(d) list of impaired
waterbodies. The discharge point falls within the Lake Wylie Nutrient Management Strategy
area, and therefore the facility will be subject to nutrient limitations upon expansion.
Permit Development
• Annlication. The previous permit expired 8/31/01. The facility's renewal application
(Standard Form A) was received by the Division on 2/ 16/01.
jj •Cyanide. Based on reasonable potential analysis, the 2000 DMR data indicated a potential
Qlt for the effluent to exceed the allowable chronic cyanide concentration (66 ug/1) and the
c4 allowable acute concentration (22 ug/1). On 9/21/00, the facility reported an effluent
concentration of 73 ug/1 and a concentration of 140 ug/1 in the west aeration basin. In
November 1999, the facility reported an influent concentration of 140 ug/1 and an effluent
concentration of 58 ug/l. Effuent data for 2001 (through August) has been below the
detection limit (<10 ug/1). The facility may request removal of the cyanide limit if data for
12-months shows effluent concentrations below the detection limit.
• Color. The facility's effluent is colored due to textile waste, however no instream aesthetic
impact is evident since the outfall is submerged and located >300-feet offshore. Therefore,
no color monitoring is recommended.
• Metals. Metals are analyzed monthly in effluent under the Pretreatment Long Term
Monitoring Plan. Copper was the only metal to show reasonable potential, but per the
Action Level Policy no limit is needed since the facility has been compliant with its chronic
toxicity test. Maintain monthly monitoring of metals under the Pretreatment LTMP.
• 24/7 Staffing Waiver Request. The facility is currently permitted for 5 MGD. At permit
renewal the facility requested a phased limit of 4 MGD be added, due to the recent loss of
several major water users and the resultant decrease in average monthly flow to only 1.6-
2.5 MGD. Since the facility's main concern was the additional cost burden of 24-hour/7-
day staffing requirement for > 5 MGD facilities per 15A NCAC 2H.0124, the facility is now
requesting a waiver from the 24/7 staffing requirement. This waiver request is under
review by the NPDES Compliance Unit.
• Downstream Station. The facility's DMRs state the downstream monitoring station at 100-
feet below the outfall pipe, while the previous permit required 1-mile downstream
monitoring. The permittee stated that the monitoring has been at 1-mile below the outfall,
and the DMR will be corrected.
• Future Expansion. Note that upon expansion beyond 5 MGD, the facility will be subject to
the Lake Wylie Nutrient Management Strategy (1 mg/1 TP and 6 mg/l TN summer). The
facility would also be subject to the Catawba Lakes Strategy, which requires the facility to
meet a minimum of advanced treatment limits (15 mg/I BOD5 and 4 mg/1 NH3-N). Based
on instream data showing low instream DO above the discharge (see below), more stringent
effluent limits would likely be required upon expansion.
• Water Quality Limited Parameters: cyanide
DMR Data.
• Effluent Physical/Chemical Data. For the period 1/01-8/01, the following range of monthly
average values were reported: 1.5-2.5 MGD [flow]; 2.8-11 mg/l [BOD]; 0.2-3.1 mg/I [NH3];
14-21 mg/1 [TSS]; 7-45 orgs/100ml [fecal]; 2-14 mg/l [TN]; and 2-20 mg/1 [TP]. Daily
maximum TRC concentrations ranged up to 600-700 ug/l.
• Effluent Toxicity Data. The facility has passed 19 of 20 quarterly chronic toxicity tests
conducted between 1997-2001. The test is conducted at an effluent concentration of 8%.

• Instream Data. For 2000/01 period, the facility reported instream monitoring data at an
upstream and downstream station. Generally there were no instream trends noted for DO,
fecal coliforms, or conductivity between stations. Instream DO values were generally above
the WQS (5 mg/1) in summer 2001, but Summer 2000 data shows several values <5 mg/l,
particularly at the upstream station. For Summer 2001, there does not appear to be any
instream exceedance of the fecal coliform WQS.
• Compliance Data. There were no compliance enforcement assessments for this facility
between 1 /94-3/00. A civil penalty of $983 was assessed for May 2000 for monitoring
violations, and a Notice of Violation was sent for a chronic toxicity test failure reported in
August 2000.
Wasteload Allocation.
• The last WLA was conducted in 1996.
Mooresville Region Data.
• The MRO submitted a staff report dated 5/23/01 for this permit renewal. The staff report
states there are no water intakes for several miles below the discharge point. The report
notes there is color in the effluent. However, since the effluent is discharged below the
surface and >300-feet offshore, no color plume is evident.
• The MRO conducted a Compliance Evaluation Inspection on 10/24/00. The MRO reported
that the WWTP operation and maintenance is commendable, and a comprehensive process
control program is used.
Miscellaneous Data.
• The city reported 6 sewer line spills totaling 68,000 gallons during calendar year 2000.

I appreciate your letting me know about this and asking for my input.
Removing the cyanide limit based on the new data and requiring
monitoring through the long-term pretreatment program sounds good to me.
I assume you will document this through an amendment to the fact sheet
or in a response to comments. See you next week. Marshall

Hi Marshall- I'm getting ready to finalize this draft permit. I
received the EPA concurrence letter, and also one comment from the
permittee. The draft included a new limit for cyanide based on monthly
effluent data for 2000 showing reasonable potential. I mentioned in the
cover letter to the permittee that their data for 2001 (through August)
was looking good (all <10 ug/1), and that they could request removal of
the limit if the trend continued. They have since sent in a letter
requesting removal of the cyanide limit, based on all 12 monthly data
points for 2001 reporting at < 10 ug/l. I would like to remove the
limit, and maintain monthly cyanide monitoring in the long-term
pretreatment program. This facility does have a quarterly chronic tox
test, which they passed 19 of 20 quarters between 1997-2001. Let me
know what you think. Thanks.

we're having a conf call w/ Mike T., Mike M., and Susan W. tomorrow
afternoon to discuss a number of issues/comments that affect several
permits we've reviewed.
I went ahead and looked at Belmont and have only 2 very minor comments
that don't need to wait for that call.
In Part A.1, the parameter name is "PH", when it should be "pH".
Also in Part A.1, TSR is specified in the table, but footnote 2
specifies TSS. I assume these need to be consistent.
I will be sending you a no comment letter for this facility.
thanks. Marshall

I would like to make one request and one comment concerning the draft NPDES permit
for our facility. The comment, we no longer utilize caustic addition as a routine way to
adjust the (pH) of the influent wastewater. The request, we would like to have the daily
cyanide limit removed based on the 2001 data set, which indicates "non -detection" for
cyanide for the year. The effluent long term monitoring chart for the year 2001 is
attached.
Your help is greatly appreciated. Sincerely,

Draft NPDES Permit NCO021181
City of Belmont
Hello folks- Please let me know if you have any comments on this internal draft NPDES permit. I hope
to get this draft out to public notice in early November, so I'll need any comments you may have by
October 31 (Wednesday, yes Halloween).
Belmont is at 5 MGD design flow and has lost several major water users, and are now averaging 1.6-2.5
MGD. At renewal they requested a 4 MGD phased flow limit be inserted, since the 7 day/24 hour
staffing requirement for > 5MGD plants was costing them. Since permit time has been lagging, NPDES
suggested they first try for a waiver and we transferrd the request to the Compliance Unit (Bob Sledge).
Mike- I'm not sure if Bob has contacted you about this waiver yet? We'll need to resolve this before the
draft goes out.
Mike- the past staff reports have mentioned color in the effluent due to textile inputs. Goodrich visited
this site several months ago, and said that although the effluent is colored, with the submered outfall
pipe discharging >300-ft offshore into Lake Wylie, he didn't notice any aesthetic impacts. Do you
concur with this? At this point I don't have any color monitoring in the draft permit.
Thanks all.

PART IV - EVALUATION AND RECOMMENDATIONS
The City of Belmont requests renewal of the subject Permit. There have been no changes to
the existing WWTP and/or the permit since the permit was last renewed. Mr. Pat Waiters (WWTP
Superintendent) indicated during the site visit a desire to have the permitted flow at this facility
reduced below 5.0 MGD. The basis for this request -is that facilities with permitted flows at or above
5.0 MGD are required to have staff present 24 hours per day. Since some industrial water users have
recently closed or left town, the WWTP has seen a reduction in hydraulic loading. Current flows
(over the past 12 months) are running anywhere from 1.87 MGD to 2.6 MGD. Belmont will be
submitting a request to have the renewed permit issued with tiered limits; one flow will be either 3.0
or 4.0 MGD, and the other flow will be the current hydraulic capacity of 5.0 MGD. When
incorporating tiered effluent limits such as this in an NPDES permit, it is equally important that
language also be included in the permit that specifically defines when the City must move from one
permitted flow to the other. Without such written guidance, compliance becomes difficult to
determine, especially when average flows are at or near the lowered tiered limit.
This facility continues to have a significant amount of color in it's effluent and, therefore,
should be included in any proposed color monitoring/study program implemented by the Division.
Pending receipt and approval of the WLA, it is recommended that the NPDES Permit be
renewed.

Hey Bob- As I mentioned today, the City of Belmont is requesting relief from the 24 hr/7day staffing
requirement for > 5 MGD facilities, as specified by 15A NCAC 2H.0124 (Reliability). Belmont is
currently permitted at 5.0 MGD. Their permit is in for renewal, and they have requested phased limits of 4
MGD and 5 MGD, to get relief from the 24/7 requirement until the flow picks up. It sounds like they lost
an operator, and don't want to hire a new one if they don't need to. Back in 1995 their monthly average
flows had reached 4.1 MGD, but with the loss of several textiles they are now in the 1.6-2.0 MGD monthly
average range. >From the permitting side, I told them that it might take 6 months before a final permit is
out, since I haven't started their review, and since EPA is holding all Municipal Major permits in limbo
until we negotitate an agreement on several issues (proper application forms, etc). Dave suggested the
waiver route as a possible quicker solution. Bob- I've left a hardcopy of their request and recent flow data
on your desk, and you indicated you would contact the MRO to determine whether they would be
comfortable with this reduced staffing request. Thanks.

RE: Addendum to Renewal of NPDES Permit
Application
o
G7�i
Mr. Weaver:
I
The City of Belmont submitted an application for renewal of its NPDES permit February
14, 2001. The City would like to modify that application and request a reduction in the
permitted effluent flow from the wastewater treatment plant. The justification for the
request is based on three major factors:
The average monthly discharge has never approached the permitted 5 million
gallons -per -day (MGD). The highest monthly average has only been 4.185
MGD obtained in February of 1995. The monthly average reached 4 MGD
three times in 1993, three times in 1994, once in 1995. It has not reached 4
MGD since 1995.
The City has lost three major water users from 1998 to 2001. The reduction
in flow amounts to an average of 0.7 MGD. The current discharge flow now
averages 1.6 MGD
• Personnel cost associated with operating the wastewater treatment facility
twenty -four -hours per -day is greatly out of balance with the current discharge
flow.
Attached to this cover sheet is a chart of the monthly discharge flows from 1992 up to
April of 2001. The material in the original application package is also included.
The City would like to request a tiered discharge limit, the lower limit being 4 MGD and
the upper limit being 5 MGD.
Thank you, for your review and consideration.

AMENDMENT TO NPDES PERMIT APPLICATION z
Background j cn o
N
O
In mid-2001 the U.S. Environmental Protection Agency, which oversees North Carolina's' o �'
NPDES permit program, determined that the state's application form for major municipal Ga
dischargers is inadequate. The EPA indicated that the form does not require a summan, of
the applicant's wastewater characteristics, as EPA's standard form does, and so does not
provide the necessary public record for permit issuance. Since July 2001, EPA has objected
to the issuance of approximately forty permit renewals until the permittees provide complete
I
applications.
In recent discussions with the Division of Water Quality, the EPA recently agreed that the
Division may provide the monitoring information on each pernvttee's behalf rather than
require the facilities to complete new applications. The permittees already submit discharge
monitoring reports (DMRs) under the terms of their NPDES permits, and the Division
can easily produce summaries for each facilty. However, the Division does not have the legal
authority to amend a facility's application; each pemrittee must give its consent in order for
the Division to submit this information on its behalf. North Carolina will provide a
summary of discharge monitoring reports as additional documentation to ensure the record
is complete
The statement below is designed to give the pemuttee's consent in this one instance. Other
than signing the statement below, no further action will be required on the part of the
permit holder. Furthermore, this will not change the substance of the draft permit
already issued by the Division.
PLEASE SIGN AND RETURN THE FOLLOWING STATEMENT AS SOON AS
POSSIBLE TO THE ADDRESS BELOW. THIS STATEMENT WILL
CONSTITUTE AN OFFICIAL PERMIT AMENDMENT.
