Subject: Issuance of NPDES Permit
NCO020184
Long Creek W WTP
Gaston County
' \Dear Mr. Shellenbarger:
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 includes the following significant changes from the draft permit sent to you
on July 6, 2005:
➢ The receiving water on the cover page has been corrected.
➢ The stream monitoring locations on page A(1) have been corrected.
In response to your comments submitted on August 1, 2005:
D "Daily sampling" means that your facility should sample 5 days per week, with the exception of
weekends and holidays. If a holiday falls on a weekday, you should report "HOLIDAY" on the
on the DMRs. If you miss weekday sampling, you may choose to sample on the weekend and
still meet the requirement.
The statement in Part 11, Section C-2: "the permittee shall at all times provide the operations and
maintenance resources necessary to operate the existing facilities at optimum efficiency" is
derived from 40 CFR 122.41 (e). The statement refers to the general requirement to properly
operate and maintain the wastewater treatment system. Spare parts, tools, and scheduled
maintenance activities would all be considered necessary "operations and maintenance
resources".
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 150E 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

September) and 1/week (October -May).
2. The monthly average effluent BOD5 and Total Suspended Solids concentrations shall not exceed 15% of the respective influent value
(85% removal).
3. The daily average dissolved oxygen effluent concentration shall not be less than 6.0 mg/L.
4. Compliance with the limit for Total Residual Chlorine shall be based upon a daily average value.
5. Chronic Toxicity (Ceriodaphnia), P/F at 19% with testing in March, June, September and December (see A. (2)).
6. The pH shall not be less than 6.0 standard units nor greater than 9.0 standard units and shall be monitored daily at the effluent by
grab sample,
There shall be no discharge of floating solids or visible foam in other than trace amounts.

Permit NCO020184
A. (2) CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 19%.
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 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 coderTGP3B'Ior the
pass/fail results and THP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to i>e'sent to the
following address:
Attention: NC DENR I DWQ I Environmental Sciences Branch
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) EFFLUENT POLLUTANT SCAN
Permit NCO020184
f#
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.

1.0 Proposed Changes Incorporated into Permit Renewal
• Effluent color monitoring will be reduced to quarterly.
• Instream color monitoring will be removed.
• Remove monitoring requirements for antimony, cyanide, mercury and silver due to lack of
reasonable potential for these pollutants to cause an exceedance of water quality standards.
Monitoring will continue to be required as part of the LTMP for this facility.
• Added nickel limit of 135 µg/L due to the results of data submitted for the LTMP.
• Added 2/month zinc monitoring due to results of data submitted for the LTMP.
• Added weekly average ammonia limits based on current permitting policy.
• Add yearly PPA requirement
2.0 Summary
Long Creek WWTP is one of two wastewater treatment plants operated by the City of
Gastonia. The plant has a permitted flow of 16.0 MGD. The facility treats domestic and
industrial wastewater collected from the northern portion of Gastonia and Ranlo and has 14 SIUs.
3.0 Compliance Summary
Efflrient DMR Data Review
Monthly average effluent DMRs data was reviewed for the period of January 2002
through April 2005. During this period, average monthly flows were at 40% capacity (6.42 MGD)
with a maximum monthly flow at 58% capacity (9.2 MGD). Monitored values for TRC, BOD,
TSS, fecal coliform, DO, and total phosphorus were all within permitted limits. The facility had
two violation for the monthly average ammonia limit during the review period: one during
January 2002 of 13.2 mg/L, and another in January 2003 of 9.6 mg/L. The Long Creek facility
also had two violations for total nitrogen in April and May, 2002: 9.9 mg/L and 6.7 mg/L,

respectively. These were the only limit violations over the course of the permit cycle. A
summary of monthly average DMR data for the limited parameters is presented in Table 1.

In the previous permit, the Long Creek facility was required to perform effluent and
instream color monitoring. They were a part of the South Fork Catawba River Water Quality
Alliance, which from April to November 2000 undertook a study of color dischargers in the river.
Following the release of the Final Color Study Report (AWARE Environmental, Inc. March 2001),
the Division of Water Quality began an effort to address the aesthetic concerns associated with
the color dischargers to the river. The result was the 2001 NPDES Color Permitting Policy, under
which Gastonia -Long Creek was classified as a Tier 2 facility. This classification would have
required that the facility perform effluent and instream color monitoring and prepare a pollution
prevention report. However, at the same time the facility lost a major industrial contributor,
Fleishman's Yeast, and requested to be re-classified as a Tier 1 facility (required monitoring and a
re -opener condition). With the lost of that industrial contribution, effluent color levels went from
an average of 558 ADMI to 40 ADMI. Instream background levels average 89 ADMI. Due to this
dramatic decrease in color levels, it does not appear that the facility currently has an effect on
instream color levels. The requirement for instream color monitoring will therefore be removed
from the permit. However, since the Long Creek Plant still has a large number of industrial
users, they will still be required to perform quarterly effluent monitoring.
Weekly average ammonia limits will be added to the permit based on current permitting
requirements for municipal facilities.
Instream Data Review
Instream data was reviewed for the period of January 2003 through April 2005. Prior to
the previous permit, the Long Creek facility entered into an agreement with the Divison to install
four automated continuous monitoring stations in the South Fork: one at an upstream location
and three at downstream locations. This agreement was reached in part to characterize instream
DO levels along a little -understood portion of the stream. Data is being collected for
temperature, DO, conductivity, and color. With the exception of conductivity (slightly higher
downstream), the discharge seemed to have little effect on the receiving stream. Instream
monitoring requirements will remain as established in the previous permit, with the exception of
color, which will be removed as described above.
Pre-treatment Data Review
This facility has 14 SIU and a full, long term monitoring program with the pretreatment
unit. As required under the LTMP, the Long Creek WWTP is required to perform quarterly
monitoring for cadmium, chromium, lead, molybdenum, nickel, and zinc. RPAs were
performed for each of these parameters and the results are discussed in the following section of
this fact sheet.

RPA Analysis
Lucent Technologies/ Salem Business Park
NC0080853
RDAs were performed for the following parameters based on DMR data submitted as a
requirement of the NPDES permit:
➢ Antimony ➢ Mercury
➢ Copper ➢ Silver
➢ Cyanide
The monitoring requirements will be removed for antimony, cyanide, mercury, and silver. None
of the data analyses for these parameters showed reasonable potential for exceedances of their
respective water quality standards. Quarterly monitoring for cyanide, mercury, and silver will
continue to be required as part of the LTMP pretreatment program for this facility. The RPA for
copper showed a predicted concentration that is higher than the allowable concentration. Since
this is an action level parameter, no limit will be added, however the 2/month-monitoring
requirement will be retained.
RPAs were performed for the following parameters based on DMR data submitted as a result of
LTMP or sludge plan requirements:
➢ Cadmium
➢ Lead
➢ Nickel
➢ Zinc
➢ Molybdenum
Data for cadmium, lead and molybdenum showed effluent levels that do not show reasonable
potential for an exceedance of water quality standards. However in February 2004 there was a
single high value for nickel of 134.0 µg/L. This is just below the allowable concentration of 135
µg/L and yielded a maximum predicted concentration for nickel that is significantly above the
water quality standard. Therefore the facility will receive a nickel limit of 135 µg/L during this
permit cycle. Monitoring for this parameter will increase to weekly.
Zinc levels also fluctuated significantly, and the data showed a maximum predicted
concentration of 390 µg/L compared to an allowable of 270 µg/L. Since this is an action level
parameter the facility will not receive a limit, however monitoring will be increased to twice per
month.
RPAs were performed for the following parameters data based on DMR data, although it does
not appear that the NPDES permit, LTMP, EPA, or the sludge program required this data.
➢ Selenium
➢ Arsenic
Data for both parameters showed only one detection out of 23 samples taken. These were
determined not to be pollutants of concern for this facility.
No RPA was performed for chloroform. Out of the 19 samples taken from January 2002 to April
2005, only one of the samples was above the detection level of 5.0 µg/L. That value was 6.1
µg/L. Although NC does not have a chloroform water quality standard, EPA has a criteria of 5.7
µg/L. The quarterly monitoring requirement will remain in the permit.
WET Test Results
The Long Creek WWTP has passed 19/19 chronic WET tests administered at 19% effluent
concentration since March 2001.

Correspondence File Review/Compliance History
The correspondence files were reviewed for the time period of 2003-2005. During this. time, the
facility seemed to have had a large number of sewer overflows. Two events were reported in
2002 totaling nearly 230,000 gallons, and five events were reported in 2003 totaling over 5.0 MGD.
Several of the heavier events (including one for 4.35 MGD in May 2003) were due to hydraulic
overload and the others were due to various equipment malfunctions. The fact sheet from the
previous renewal also maces reference to large sewer overflow events from 1999-2001. It does
not appear that there have been any sewer overflows since May, 2003.

Its looks like the difference in WET testing requirements and IWC are perhaps due to
a mistake in a previous pemit that was carried over. The facility has been testing
at 11%, not 110%, so they (the facility and Aquatic toxicology unit) must have caught
the mistake. I'll double check with AgTox and fix the mistake. I have no objections
to your other comments, I'll make those changes.

hope these are useful.....
1, fyi, the cover letter to Mr. Shellenbarger is dated 7/6/04.
2. for TRC, since the previous permit limit was 28.0 ug/1, I recommend
retaining that significant digit in this permit.
3. Ni, Cu, and Zn should be expressed as "total".
4. shouldn't the units for color measurements be specified? should
color samples be grab?
5. Z assume the City has a pretreatment program. If so, the fact
sheet should state that the permittee will continue to implement its
existing pretreatment program.
6. The WET limits are based on a 19% concentration. However, the
table on pg. 1 of the fact sheet says the IWC is 10.2%. Pis explain
why there is a difference.

Dear Ms. Fields:

PoNli 5odlioi. Bf{INCH
Thank you for sending us the draft of Long Creek WWTP's renewed NPDES permit.
We have reviewed this draft, and in accordance with your request, we are submitting
the following comments on what appear to be typographical errors:
• Cover page: Receiving waters listed here should read "South Fork Catawba River"
• Section A(1) Notes: Stream Monitoring locations listed are not correct (Do not
intersect South Fork River). Historically for Lonq Creek WWTP these locations have
been:
o Upstream: Highway 275 or 200 feet above outfag/1
o Downstream A: Spencer Mountain Pool at dam
o Downstream B: South Fork River bypass at NCSR 2003
o Downstream C: 1.5 miles below tailrace at power lines
We would also like some clarification on the definition of "daily sampling" in Part II
Section A. Does this mean we need to sample five days each week even when one day
is a holiday? Does it mean if we do not obtain a sample - due for instance to a
malfunctioning sampler - we can sample on the weekend and still meet the requirement?
We ask clarification as well for what is meant by "The Permittee shall at all times provide
the operations and maintenance resources necessary to operate the existing facilities at
optimum efficiency" (Part Il, Section C-2).

Re: Renewal Application of Permit NCO020184 Long Creek WWTP
Dear Ms. Stephens:
On behalf of the City of Gastonia, I am requesting renewal of the National Pollutant
Discharge Elimination System Permit #NC0020184 for the Long Creek Wastewater
Treatment Plant. A permit application and associated information including a sludge
management plan are being submitted along with this letter. This permit renewal
application is being submitted by the August 4, 2004 deadline to comply with
requirement to apply 180 days prior to the date of permit expiration (January 31, 2005),
As requested, please find the original signed version of this information along with two
copies.
The Long Creek Wastewater Treatment Plant continues to operate as an advanced
biological nutrient removal plant treating municipal wastewater for the City of Gastonia.
Numerous minor upgrades have taken place at the plant since the previous permit
renewal request, which have all been made to enhance the treatment process and
efficiency. Examples include replacement of malfunctioning aeration basin recycle
pumps and mixers, buying replacement of filter media and nozzles, beginning
replacement of aeration basin diffusers, construction of filter flow diversion, improved
chlorine/sulfur dioxide control system, and improved SCADA process control. As is
further described in the attached sludge management plan, the most notable change is
that anaerobic digesters at the plant have been repaired and placed back into service to
treat the sludge generated in the treatment process. Accordingly the lime stabilization
process for treating these solids has been eliminated.
All analyses have been tested by North Carolina certified laboratories in accordance
with 40 CFR Part 136 requirements. This application includes all data gathered for the
A A ISO 14001 Certified
A wspft Quoty A""— Pure and`Crean for our fields an f Streams

last four and one half years up through June 30, 2004. Efforts have been made to
obtain seasonal variation in the sampling as much as was possible. One oil and grease
analysis on an effluent sample showed a surprisingly high result that did not appear to
be representative of the discharge, however it was not possible to retest the sample so
this data was reported. Additional oil and grease testing was conducted to determine
the accuracy of that result with all results being below detection.
If you would like any additional information, or if I can be of any assistance please feel
free to call me at 704-866-6991 or e-mail at [e-mail].
Sincerely,

Section 13.1. Inflow and Infiltration.
Briefly explain any steps underway or planned to minimize inflow and infiltration.
The City of Gastonia seeks to correct all sources of inflow or infiltration, Inflow and infiltration has been of
particular concern in the older portion of Gastonia's collection system, which feeds into the Long Creek Wastewater
Treatment Plant. This area was extensively smoke tested as part of a sewer system evaluation study to identify
sources and extent of inflow/infiltration. Based on these identified sources the City is undergoing efforts to eliminate
them. The following are the major projects that have been identified and their current status:
• Linwood Road Sewer Rehabilitation Project — In 2002, Gastonia invested $237,150 to complete a project to
rehabilitate 2500 LF of 8" sewer by cured in place lining in Linwood Road from Franklin Boulevard to
Spencer Avenue. Active sewer services were also renewed to the street right-of-way.
• Firestone Mill storm drain connections — The possibility of roof drain connections to the sewer system were
identified during smoke testing as part of the sewer system evaluation study. The City is working to have
these connections removed. Firestone has made some corrections to their portion of the site and some
corrections to the portion of the site {the old mill building} that is currently owned by Preservation North
Carolina. Some follow-up smoke testing has verified that some of the connections have been removed. The
City is continuing to work with Firestone and Preservation North Carolina on this site.
• Osceola Mill - The possibility of roof drain connections to the sewer system were identified during smoke
testing as part of the sewer system evaluation study. City staff is currently trying to contact the property
owner of this closed facility to gain access for further evaluation of the situation.
• Abandoned Wastewater Collection Systems - It is suspected that several of the abandoned wastewater
collection systems in some older mill neighborhoods remain connected to Gastonia's existing wastewater
collection system. This was identified in the sewer system evaluation study as a possible source of
significant inflow/infiltration. The City will further investigate this potential source and do the necessary
work to disconnect any such lines. It is expected that substantial work will be needed on both the private and
public stormwater systems at these old mill sites. The City expects it will require an additional 5 years to
completely divert the stormwater from these mills and abandoned lines-
• Armstrong Branch Sewer Line Rehabilitation — Design for this project has been completed and the City is
currently in the process of obtaining right-of-way and seeking approval of a STAG grant for this project.
• Dillard Creek Outfall Manhole Rehabilitation — The design phase of this project has been completed and the
City is going to bid with this project.
• Niblick Drive Sewer Line Rehabilitation — Rehabilitation of this line has been approved and designed. The
project is currently under contract with a firm to complete the rehabilitation.

Section 13.3. Process Flow Diagram or Schematic
Process Flow Description
The Long Creek WWTP is a 1 G-mgd facility operated by the City of Gastonia which
' discharges to the South Fork River. influent wastewater enters the plant through a 48"
gravity feed sewer line and passes through coarse manual and fine mechanical screens
and a Detritor grit collector. Following preliminary treatment, the flow enters the main
lift station. Five influent pumps (three duty, two standby) lift the influent flow to
Manhole 41 (MH-1) and the flow is split to three primary clarifiers. The primary clarifier
effluent is combined with the RAS in MH-2 where the flow is split to two biological
' treatment trains. The biological treatment trains consist of anaerobic, anoxic and oxic
basins, with internal oxic recycle pumping (one duty, one standby per train) for
denitrification. One biological treatment train has a capacity of 7-mgd and the other has a
capacity of 9-mgd. Following the biological treatment trains, flow is combined in MH-6
and routed to the denitrification basin which consists of anoxic zones for further
denitrification and oxic zones for reaeration. Flow can be diverted around the
denitrification basins. This flexibility was provided because the plant is only required to
meet a total nitrogen limit in the summer months. The intermediate pumping station
consists of three screw pumps (two duty, one standby) which li ft the flow to four final
clarifiers. From the final clarifiers, the flow is sent to gravity anthracite filters. Eight
filter cells are used to allow filter cells to be taken out of service without impacting the
performance of the system. Flow can be diverted around the filters. Filter effluent is
disinfected in an open chlorine contact chamber by injection of chlorine solution. Sulfur
dioxide is injected into the chlorinated effluent for dechlorination. Finally, the effluent is
discharged through two three -stage static aeration devices to a 54" line, which discharges
to Long Creek. The process flow schematics show all of the processes of the treatment
plant along with bypasses and backup power sources. The plant has three 1,600 kW
generators located at the plant entrance.

Additional Information for NPDES Permit Application
Sludge Management Plan
for
Long Creek Wastewater Treatment Plant
NPDES Permit # NCO020184
The Long Creek Wastewater Treatment Plant (WWTP) design for sludge handling consists of
anaerobic sludge digestion followed by land application. Between 1999 and 2002 solids at the
Long Creek WWTP were handled through a lime stabilization process, but in Fall 2002 the
anaerobic digesters were cleaned, repaired and placed back into service. This plan describes the
processes in place for treating and disposing of this material.
Anaerobic Digestion:
The anaerobic digestion system consists of six anaerobic sludge digesters, each with a volume of
approximately 450,000 gallons, which treat the primary and waste -activated sludge from the
WWTP. On average, the City of Gastonia sends approximately 60,000 gallons of raw and
thickened wasted solids to these digesters each day for treatment. Two of the digesters are
heated and operated as primary digesters, the other four are utilized for sludge storage.
Raw sludge from the bottom of three primary clarifiers is pumped to the two primary digesters
where it is held at a temperature greater than 35'C. Wasting from the secondary clarifiers is also
pumped to the primary digesters, however these solids are first thickened in the dissolved air
floatation thickener unit located adjacent to the digesters. From the primary digesters, solids are
then pumped to the holding digesters and then into the sludge storage lagoons.
The WWTP has two biosolids storage lagoons, with a combined capacity of four million gallons.
Additionally, the City of Gastonia operates a residuals storage facility at the City of Gastonia's
Resource Recovery Farm located between Dallas and Cherryville. This facility is capable of
storing an additional eight million gallons of biosolids when application activities are hindered
by inclement weather.
The Long Creek WWTP currently complies with the 503 pathogen reduction requirement for
Class B biosolids by a PSRP process (40 CFR Part 257 Appendix II). Pathogen reduction is
demonstrated by fecal coli form testing or documentation of primary digester MCRT and
temperature. Vector attraction reduction is demonstrated by a measurement of 38% volatile
solids reduction using the Van Kleeck's equation or a 40 day additional anaerobic digestion
bench scale test.

Land Application Program:
For beneficial reuse of these biosolids, the City of Gastonia utilizes land application for disposal
of these solids. For the past three years, Gastonia has had a contract with Otter Creek
Environmental to perform this land application but has recently started utilizing EMA Resources,
Incorporated to perform this function. Biosolids are land applied to 2,273.2 acres of local
farmland throughout the county, in accordance with NCDENR Land Application Permit
WQ0001793. One hundred eighty-two of those acres are on City owned land at the Resource
Recovery Farm and the remainder is private farmland.
Environmental Management System:
The City of Gastonia's Wastewater Treatment Division, which includes the biosolids program,
has implemented and operated under an ISO 14001 Environmental Management System since
2001. The City has seen many benefits from this program in better organization, improved
compliance, controlled environmental impacts and greater efficiencies. Because of these
benefits, the City is in the process of instituting the National Biosolids Partnership
Environmental Management Program. The City believes that this program will help further
improve some aspects of its biosolids handling. In particular, it is believed that through this
program the biosolids program will benefit from inclusion of the City's contractor in the
environmental management system, inclusion of the best management practices in the program,
improved public acceptance of the program and a greater emphasis on biosolids quality.
Future Plans:
Gastonia has just completed an extensive Wastewater Master Plan Study. One of the areas
identified for future work was the digester complex at the Long Creek WWTP. The City is
currently selecting consultants to lead design and extensive rehabilitation of these digesters to
ensure their effective operation in the future.
