Subject: Issuance of NPDES Permit NC0025496
Lincolnton WWTP
Lincoln County
Dear Mayor Huitt:
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 the following modifications from the draft permit previously sent to you on July
25, 2001:
• The cadmium limits (daily maximum and weekly average) have been deleted from the permit. The
results of a reasonable potential analysis (RPA) indicated that the effluent does not have the potential to
cause a violation of the water quality standard. Monitoring for cadmium will remain in the Pretreatment
program's Long Term Monitoring Plan.
• Color monitoring and reduction requirements have been modified based on your facility's
reclassification as a Tier 3 color discharger. The Tier 3 reclassification was based on actual
conditions observed at the Lincolnton WWTP during a site visit, additional information received during
the public hearing, and results of the AWARE Environmental study.
The water quality standard for color is a narrative standard from North Carolina regulation 15A NCAC
2B.0208(f): "Oils, deleterious substances; colored or other wastes: only such amounts as shall not render the
waters injurious to public health, secondary recreation or to aquatic life and wildlife or adversely affect the palatability
of fish, aesthetic quality or impair the waters for any designated uses; for the purpose of implementing this Rule, oils,
deleterious substances, colored or other wastes shall include but not be limited substances that cause a film or
sheen upon or discoloration of the surface of the water or adjoining shorelines....".
The effluent from Lincolnton's WWTP has affected the aesthetic quality and discolored the surface of
the water in the South Fork Catawba River. The additional information provided by Lincolnton
regarding events that affected the plant's effluent during the August 28th site visit was considered by
Division staff; however, with all factors reviewed, especially number of color contributors to the
Lincolnton treatment system, the tier upgrade is deemed appropriate.

The Tier 3 reclassification requires that Lincolnton also prepare a color reduction study, in
addition to the BMP report, which was required under the previous Tier 2 classification. The
special condition is as follows:
This facility has been classified as a Tier 3 color discharger. The permittee will conduct color monitoring of
instream stations (upstream, downstream) on a monthly basis during summer season (April -October). The permittee
will record whether a color plume was observed around the outfall pipe during the monthly instream sampling
events, and include that information on the monthly discharge monitoring report. Effluent samples will be collected
monthly for color on a year-round basis. Color samples will be analyzed for ADMI color at natural pH. Effluent
samples will consist of 24-hour composites, while instream samples will be collected as grabs. Samples will be
analyzed by a state certified laboratory.
The permittee will prepare a Pollution Prevention/Best Management Practices (BMPs) report. This report will
address the potential for the facility to reduce effluent color by incorporating pollution prevention measures and/or
BMPs prior to treatment. This report could include an evaluation of the dyeing process, looking at the potential for
dye substitution, improving dyeing efficiencies, etc.
The report could also investigate whether any BMPs could be implemented that would reduce the amount of color
discharged to the treatment plant. The permittee could do this work independently, or request voluntary assistance
from the North Carolina Division of Pollution Prevention and Environmental Assistance. The permittee will also
prepare a Color Reduction Study, which will involve an end -of -pipe treatment evaluation that develops cost
estimates for reducing effluent color by 75% and 90%. Both reports will be submitted within 24 months of the
permit effective date.
If data show that water quality standards for color are being violated by the discharge permitted by the terms of this
permit, then the Director may reopen this permit for the purpose of imposing additional requirements pursuant to
15A NCAC 2H.0114. Alternatively, if future conditions change and color is no longer a component of the influent
wastestream, then the permittee may request a permit modification to remove color permit requirements.
• The results of all tests on the characteristics of the effluent, including (but not limited to) NPDES
Permit Monitoring Requirements, shall be reported on monthly report forms (per North Carolina
regulation 15A NCAC 2B.0506 (b)(3)(J)). All future effluent metals data submitted for Lincolnton's
Pretreatment Long Term Monitoring Plan should be reported on the Discharge Monitoring Reports
(DEM Form MR-1).
The following conditions from the draft permit remain in this final permit:
• The cyanide limit of 22 µg/1 (daily maximum) remains in the permit. The results of the RPA
predicted that the effluent has the potential to cause a violation of the water quality standard. Effluent
data used in the analysis indicated several reported cyanide values that exceeded the allowable
concentration for protection of the standard.
• The mercury limit of 0.1 µg/1 (daily maximum) remains in the permit. The results of the RPA that
predicted that the effluent has the potential to cause a violation of the water quality standard. Mercury
continues to be a water quality concern throughout North Carolina. NPDES permittees have worked with
the state to reduce potential risks from this pollutant, including tasks associated with collecting and
reporting more accurate data. The most commonly used laboratory analysis (EPA Method 245.1) has a
detection limit of 0.2 µg/L while the current water quality standard is an order of magnitude lower at
0.012 µg/L. A more recently approved analytical test (EPA Method 1631) should produce a detection
limit below the level of the standard. This will allow the Division to assess potential water quality
impacts from discharges more accurately. Therefore, beginning on or before September 1, 2003, you will
be required to begin using EPA Method 1631 when analyzing for mercury.

Page 3 of 3
After permit issuance, if Lincolnton has twelve consecutive months of mercury values below the
detection level, then the City may submit a written request asking DWQ to re-evaluate the assignment of
a mercury limit in the NPDES permit.
• Effluent monitoring for copper will remains in the permit. Copper monitoring has been increased
to 2/month based on requirements for Class III and IV facilities.
• Monthly monitoring for zinc remains in the permit. The Division's concerns regarding discharges of
zinc from municipalities (and their potential effect on toxicity) require that zinc monitoring continue.
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.
Please take notice that this permit is not transferable. 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, Coastal Area
Management Act, or any other Federal or Local governmental permits may be required.
If you have any questions or need additional information, please contact Ms. Jacquelyn Nowell at
telephone number [phone], extension 512.
Sincerely,
Alan W. Klimek, P.E.

Permit NC0025496
A. (2). CHRONIC TOXICITY PERMIT LIMIT (Quarterly)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 11 %.
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 11 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: NC DENR / DWQ / 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.

Permit NC0025496
A. (3) COLOR PERMITTING REQUIREMENTS FOR TIER 3 FACILITY
This facility has been classified as a Tier 3 color discharger. The permittee will conduct color monitoring of
instream stations (upstream, downstream) on a monthly basis during the summer season (April 1— October 31).
The permittee will record whether a color plume was observed around the outfall pipe during the monthly
instream sampling events, and include that information on the monthly discharge monitoring report. Effluent
samples will be collected monthly for color on a year-round basis. Color samples will be analyzed for ADMI
color at natural pH. Effluent samples will consist of 24-hour composites, while instream samples will be
collected as grabs. Samples will be analyzed by a state certified laboratory.
The permittee will prepare a Pollution Prevention/Best Management Practices (BMPs) report. This report will
address the potential for the facility to reduce effluent color by incorporating pollution prevention measures
and/or BMPs prior to treatment. This report could include an evaluation of the dyeing process, looking at the
potential for dye substitution, improving dyeing efficiencies, etc. The report could also investigate whether any
BMPs could be implemented that would reduce the amount of color discharged to the treatment plant. The

SECTION
As you requested, I served as Hearing Officer for a public hearing to obtain comments
relative to the proposed color removal requirements necessary for the renewal of the above listed
draft NPDES permits. The hearing was held at 7:00 p.m. on August 28, 2001 at the Citizen's
Resource Center in Dallas, NC. The hearing was held in response tonumerouscomplaints about
the colored effluent plumes from some of the above permitted facilities. These plumes are
primarily due to the large number of textile dischargers in the Catawba River Basin.
BACKGROUND
15A NCAC 02B.0211(3)(f) states, in part, that colored wastes are allowed only in " such
amounts as shall not render the waters injurious to public health, secondary recreation or to
aquatic life and wildlife or adversely affect the palatability of fish, aesthetic quality or impair the
waters for any designated uses". Noticeably colored effluent from the above facilities, as well as
others, in the Catawba River Basin has been the subject of an ever increasing number of
complaints over the years. However, there has been no evidence collected by the Division, nor
presented by others, to indicate that these facilities are having anything other than an aesthetic
impact on the receiving stream.

The Division and several of the major color dischargers met in 1999 to discuss ways to
address the color issue. From this meeting, the South Fork Catawba River Water Quality
Alliance was formed to conduct color monitoring and assess the color problems in the watershed.
The data collected by the Alliance was incorporated into a final Color Study Report that was
submitted to the Division in March of 2001. This report documented noticeable color plumes
from the various discharge locations ranging from "no plume observed" at the Pharr Yarns
WWTP to " > 8.3 miles" for Delta Apparel. Water Quality Section staff also conducted
independent color evaluations during a site visit to the discharge locations in August of 2000.
Numerous photographs and water samples were taken, documenting the color problems in the
watershed. Based upon the findings of the Color Study Report prepared by AWARE
Environmental, Inc. and field visits by Water Quality Section staff, a NPDES Color Permitting
Policy for Catawba River Basin Color Dischargers was developed by the NPDES Unit and
approved by the Director on June 13, 2001. A copy of the policy is attached as Attachment A.
The NPDES Color Permitting Policy places the color dischargers into one of four tiers.
Basically, Tier 1 dischargers will only be required to monitor for color. Tier 2 dischargers will
be required to monitor for color, plus prepare a Best Management Practices Report to address the
potential for reducing effluent color. Tier 3 dischargers must comply with the Tier 1 and Tier 2
requirements, plus conduct a color reduction study to identify the cost associated with reducing
influent color by 75% and 90%. Tier 4 facilities will be required to achieve a 90% color
reduction between their influent and effluent. The tier system, with associated dischargers, is
explained in detail in the policy.
SITE VISITS
Jackie Nowell, Natalie Sierra, Dave Goodrich, Tom Belnick and I departed Raleigh the
day before the hearing to conduct site visits at the various discharges and see the effects of color
first hand. Our first stop was Gastonia's Crowder's Creek facility where we met with the
Director of Utilities, Don Carmichael and others. While supporting the Division's attempts to
reduce color, Mr. Carmichael was concerned that the Crowder's Creek facility had been placed
in Tier 3, since that facility was not a part of the original Alliance study. His concerns stemmed
from the fact that funds to meet the Tier 3 requirements had not been budgeted by either
Gastonia or Kings Mountain, who is the primary source of color at the Crowder's Creek plant. I
am uncertain as to why this facility was not a part of the original color study since their effluent
was extremely red on the day of our visit and appeared to constitute approximately 50% of the
flow in the receiving stream. The color of the receiving stream remained extremely red at the
Forbes Road bridge approximately one mile downstream.
Next we joined Carol Kemker from EPA -Region IV at the Yorkshire America's, Inc. dye
manufacturing plant. We toured their wastewater facility, discussed the improvements that they
had made, and hiked down to the discharge location. On the day of our visit, there was no
discernible color or plume in the receiving stream.
2

Gastonia's Long Creek discharge location was our next stop. Don Carmichael and other
city representatives met us there and explained that there had been a dramatic color reduction in
their effluent since the closure of the Fleischman's Yeast manufacturing facility. From our
vantage point directly above the discharge pipe, the effluent appeared to be very clear with
perhaps a very light green tint. The plume did not appear to be noticeable in the receiving
stream.
We spent the night in Hickory, which is worth mentioning only because Hickory is
located in the upper end of the watershed and we experienced a fairly intense rain event there
overnight. While we did not retrace our steps of the previous day, the additional stream flow
from stormwater runoff may have masked the color of the dischargers we visited on the 28th to
some degree.
Our first stop on the 28th was Hickory's Henry Fork wastewater treatment facility. The
color of effluent at the discharge location was the color of weak tea, but immediately turned to a
very dark color upon contact with the receiving stream, which appeared to be heavily laden with
sediment. It quickly dissipated, however, and was not noticeable a short distance downstream at
the next bridge. One of the difficulties of addressing a color problem in the stream was
demonstrated during our lab visit. Separate samples of plant effluent and water from the stream
appeared to be indistinguishable when compared in lab flasks, contradicting the actual conditions
at the discharge location.
Delta Apparel, Inc. was our next stop where we met with the plant manger, the
wastewater treatment ORC, and their lawyers. Delta Apparel, Inc. employs approximately 400
people and is the only permitted discharger in the basin to be placed in Tier 4 in accordance with
the Division's NPDES Color Permitting Policy. The concerns expressed in this meeting centered
around the proposed 90% color reduction requirement and the fact that all of their monitorirag to
date used the Platinum -Cobalt method rather than the ADMI process required by their draft
permit. It is uncertain how the data from the two testing methods would relate and whether a
90% reduction by the Platinum -Cobalt method would equate into a 90% ADMI reduction. (Note:
According to the Standard Methods for the Examination of Water and Wastewater, the Platinum -
Cobalt method is not applicable to most highly colored industrial wastewaters, whereas the
ADMI test was developed by the American Dye Manufacturer's Institute for colored waters and
wastewaters.) The Delta representatives were especially concerned that they couldn't meet a
90% reduction of color when producing lightly colored influent. Apparently, their dye operation
varies widely in response to the needs of their customers, and it would be very difficult to clean
up relatively clean water. Ironically, the plant manager did not want to be held to a specific
number limit either. Rather, he suggested that Delta be placed in Tier 3 for at least another
twelve months so they can continue monitoring through all four seasons using the ADMI
method.
Delta's influent color was extremely black or deep purple on the day of our visit. They
were continuing to add polymer and appeared to be removing a good bit of color, although the
effluent was still very dark. At the discharge location, the dark effluent quickly dissipated within
about 50 yards downstream of release. This situation represents a tremendous improvement
over that which was observed by Division staff on previous visits, although it remains unclear if
the previous night's rain was a factor.
3

The Lincolnton facility was our next stop. We were told by the wastewater treatment
plant personnel that approximately 65% of their flow comes from industrial sources, and that
there are six textile plants with dyeing operations contributing to their influent. The receiving
stream upstream of their discharge was a reddish brown color on the day of our visit. The city's
discharge, however, was a dark gray to black and created a very noticeable plume. The color of
the entire receiving stream was noticeably darker at a bridge about a quarter -mile downstream.
Again, it was impossible to determine if either the upstream or downstream color had been
influenced by the recent rain.
Our last stop was the City of Cherryville's wastewater treatment facilities. We were told
that their only textile discharger was no longer in business. As a result, their effluent discharge
appeared colorless.
PUBLIC HEARING
Approximately 39 people attended the public hearing. Those providing oral comments
were Representatives from the City of Gastonia, City of Lincolnton, Cooperative Extension
Service of Gaston County, the Catawba River Keeper and a Cove Keeper. Copies of all written
comments received are contained in Attachment B to this report.
All speakers were supportive of the tier system as outlined in the NPDES Color
Permitting Policy for Catawba River Basin Color Dischargers. The municipal representatives
were primarily concerned over the rate impact of conducting additional studies and the cost of
possible new construction. The River Keeper, Cove Keeper, and Cooperative Extension Service
were all concerned over the as yet unknown impacts of color on aquatic life. The River Keeper
also wanted Lincolnton's WWTP and Gastonia's Crowder's Creek WWTP moved to tier 4. All
of the speakers were very supportive of the tier system approach.
Delta Apparel had previously asked for additional time to submit technical data
supporting their voluntary efforts to reduce color in their effluent. Therefore, the comment
period was extended until September 23, 2001. Additional comments were also received from
the City of King's Mountain who is concerned that too many additional requirements will force
mills to close, eliminating jobs and leaving the remaining customers with excessively high user
rates, and from a private citizen urging us to hold firm with a 90% reduction requirement for
Delta Apparel, Inc.
After the close of the hearing record, additional data was requested from Delta Apparel,
Inc. in an effort to determine the amount of polymer being added and the resulting color
reduction achieved as measured by the ADMI method. Delta took exception to our requests for
the additional information and objects to a 90% removal requirement. Copies of correspondence
with Delta are attached in Attachment C.

FINDINGS & RECOMMENDATIONS
At best, color removal for aesthetic purposes appears to be an inexact science, which is
mastered as often by trial and error as by scientific calculations. I believe that the tiered
approach, as outlined in the NPDES Color Permitting Policy for Catawba River Basin Color
Dischargers, provides an appropriate mechanism for attenuating the impacts of color
dischargers —not only in the Catawba River basin, but in others as well.
Based upon comments received at the hearing, the additional data finally submitted by
Delta Apparel, Inc., and visual observations during our site visit, I recommend the following:
• Yorkshire Americas, Inc. —On the day of our visit, this facility no longer seemed to
have a color problem. However, due to the nature of their business, I believe that they are
appropriately included in Tier 2 and should be required to prepare a Pollution Prevention
/ Best Management Practices report.
• Gastonia -Long Creek & Cherryville—With the closure of the major industrial color
contributors to their wastewater treatment plants, these facilities no longer seem to have
color problems. Therefore, I recommend that they both be moved into Tier 1 with a color
reopener special condition.
• Hickory -Henry Fork —I believe that this facility is appropriately placed in Tier 3.
• Gastonia-Crowder's Creek —Since this facility was not a part of the original color study,
and since this permit cycle will expire on July 31, 2005, I concur with the Tier 3
designation. However, Gastonia should be advised that this facility will be placed in Tier
4 at the next permit renewal unless there is a significant improvement in the color of their
effluent.
• Lincolnton—Based upon the comments received at the public hearing and the actual
conditions observed during our site visit, I believe that Lincolnton should more
appropriately be designated as a Tier 3 facility. A Tier 3 designation requires the
preparation of a color reduction study within 24 months of the permit's effective date.
The Division would then have time to determine if this facility should move to Tier 4 for
the next permit cycle.
• Delta Apparel, Inc. —Based upon the test data available to us at this time, I concur with
Delta's argument that it would be difficult for them to consistently meet a 90% color
reduction when their dye use varies from 65% to 2% as stated in their attorney's letter of
September 21, 2001. However, data collected by the NPDES Unit reveals that other
textile and municipal facilities are able to achieve 90-plus percent color removal and
produce an effluent with ADMI ranges of between 400 to <25 units (see Attachment D).
•
Therefore, I believe that Delta is appropriately designated as a Tier 4 facility and should
have a specific color limit —expressed either as a percentage reduction or in ADMI units.
The ADMI test data submitted by Delta for the period of July 24, 2001 through December
4, 2001, indicates that they have achieved color reductions varying from 46% to 93%.
The highest monthly influent color average during this time frame was 5754 ADMI units.
The highest monthly effluent color average during this time was 860 ADMI units. (The
effluent color on the day of our visit was 748 ADMI units) I believe that it would be
5

appropriate to assign a color limit to Delta that we are reasonably comfortable that they
can achieve and gradually ratchet it down, over time, to a point that the color discharged
would neither be objectionable nor detrimental to the stream.
Therefore, it is my recommendation that the permit contain a phased monthly average
ADMI limit. Phase I of the permit cycle would run for 12 months from the date of
issuance and contain an ADMI limit of 863 units, which represents an 85% reduction from
their highest monthly influent concentration for which data is available. Delta's data
indicates that a limit of 863 ADMI units is attainable. Phase II of the cycle would follow
for the next 12 months and require them to meet a monthly average ADMI limit of 720
units. The final phase, running through the end of the permit cycle in 2005, would require
compliance with a monthly average ADMI limit of 575 units. The final ADMI limit of
575 units represents a 90% reduction from their highest influent average of 5754 units,
which occurred in October of 2001. Influent ADMI values, as well as the brand name,
quantity and cost of any polymer additions should also be reported monthly. The permit
should also contain a color re -opener clause that would allow additional requirements to
be imposed should conditions warrant.
Finally, I'd like to commend the efforts of the staff of the NPDES unit for their work in
developing the color policy, their research and assistance in collecting and analyzing data, and
preparing for the hearing. There doesn't appear to be a great deal of technical literature available
on color removal and their input has been invaluable.

Marshall,
In response to your comments about Lincolnton (NC0025496), regarding
Item 1) Cu and Zn - attached is an email from Susan Wilson with a brief
explanation on DWQ's guidance on the Cu and Zn action levels. Hopefully
this will clarify the issue. Susan did review the Lincolnton facility
after the June 2001 test and determined that reasonable potential did
not exist for Cu or Zn to exceed the action level and therefore no
limits were assigned.
I reviewed the WET testing self monitoring summary and found that
Lincolnton had a "did not report" in Dec. 2000, which was followed by a
PASS. There were two FAILs in June and September 2001. Each FAIL was
followed by two toxicity tests where the facility passed. Because of
these followup results, no enforcements were levied. I'm unsure whether
the facility put the followup test results on their DMRs, but it was
reported to the Aquatic Toxicology Unit and reported on the summary
database.
Item 2) Will make the parameter "Total Suspended Solids" in both places.
Item 3) This has been resolved by specifying " Total" metals in permits.
Please contact me if there are additional questions (919)-733-5083 x512
. Thank you.

Marshall/Jackie:
Here's a copy of what the NPDES Unit actually does in evaluating the
data for copper and zinc based on the approved action level guidance
submitted to EPA. I'm not sure I have the copy of the letter/document
sent to EPA out of the Aquatic Toxicology Unit - but this written
guidance expresses how we're dealing with the data once the ATU sends us
a list of the permittees that have an initial toxicity failure.
Marshall - note that we re -calculate the allowable level (through the
metal translator method and the 15th percentile TSS data for the
subbasin of the discharge). Therefore, you can't do a direct comparison
between the action level standard allowable and the DMR values (it's
more complicated than that - but the calcs. are laid out in this
guidance). We may need to conference call with you about this next week
if it's unclear, as well as some other items.

yesterday's conf call with Dave, Mike, Susan, and Mike cleared some

draft permit. Please email me your response. Feel free to correct any
assumptions I made. Call me at [phone] if you want to discuss
further. thanks. Marshall
1. Cu and Zn:
although there appear to be data entry errors in the DMR, the avg values
for these seem to me to exceed the action level criteria. The WET DMR
data show 2 test failures for 2000. I thought NC's policy was that if
there are WET violations and action levels are being exceeded, that
chemical -specific limits for those action level criteria would be
required. Pls explain your decision to not include limits for Cu and
Zn. I was also curious why the DMRs didn't reflect followup WET testing
for the 2 failures.
2. wanted to point out that the table in Part I.A specifies TSS, but
footnote 2 below cites TSR. I assume these should be consistent.
3. 40 CFR 122.45(c) requires that metals in permits be expressed as
total recoverable, unless another form is appropriate. Why aren't the
metals in this permit expressed this way?

Ms, Nowell:
I have talked with James Rhyne, WWTP Superintendent, about the visit ofBobby
Biowe to our Plant. The discharge of color that day was not at all typical of our usual
effluent, James has compiled a list of events that had taken place that had an
extremely negative effect on the color of our discharge. Please consider this

Subject: NPDES Permit Renewal — Jackie Nowell Telephone Conversation
Steve,
Per our conversation with Jackie Nowell yesterday, I would like to give you an account of the events that
took place prior to her on -site inspection of our WWTP. These events led to the poor quality of effluent that
was present that day and is being used to possibly place us as a Tier 3 instead of a Tier 2 concerning color.
I feel that it is unfair for the state to judge us on this ottc visit when they were advised that our plant was in
an upset condition due to circumstances beyond our control. .' )
On August 28, 2001, Jackie Nowell and others from the State visited our WWTP for an: inspection for
permit renewal reasons.
On August 22, 2001, Geymont Construction Inc. was dentolitioning around #3 Primary Clarifier when they
hit a 30" line that connected with the 111 and #2 Trickling Filter Splitter Box. We immediately opened the
Trickling Filter bypass Iine. This bypass line had not been used in over 10 years. This in turn, created a
septic slug load directly into the Aeration Basin. The Trickling Filters were bypassed for 16 hours. The heat
of August caused all the Trickling Filter Media to be killed, This dead media went directly into the
Aeration Basin upon the Trickling Filters being returned to operation at 7:00a.m. Thus, creating another
slug load to the Aeration Basin.
On August 23, 2001, both our Return Sludge Pumps failed at manhole #28 at 9:00 p.m. We had to take the
and #2 Final Clarifiers out of operation We called a contractor on August 24, 2001 to repair valve. The
repairs could not be made until early morning August 28, 2001. The #1 and 42 Final Clarifiers were put
back in operation at 12:30 p.m., the day of time inspection.
We are currently using bypass pumps at the intermediate lift station When we dropped the #1 and #2 Final
Clarifiers, we lost 33% of our Secondary Treatment. In turn, we diverted all our return sludge into #3 and
#4 Final Clarifiers. When all 3 of the bypass pumps were running, it caused a surge, which caused our
suspended solids to go,}tp because of a higher than normal sludge blanket in #3 and. #4 Final Clarifiers.
This is evident on the Oita on our DMR for August 2001.
We feel this chain of events caused a poor effluent quality that was evident during the plant visit on August
28, 2001. This poor effluent quality was caused by the upset condition at the WWTP and the em.uent
observed that day is not typical of the City of Lin.colnton's effluent.

Subject: Response to Draft Permit No. NC0025496
Ms. Nowell:
Thank you for the opportunity to respond to the above -mentioned Draft Permit for the
City of Lincolnton Waste Water Treatment Plant.
The City of Lincolnton currently has a cyanide limit of 184 ug/l (daily maxim — with
a 46 ug/1 weekly average). To reduce this limit to 22 ug/1 (daily maximum) is
oppressive. We believe that the current limit is more realistic.
Our current Permit does not contain a mercury limit. Based on data from our Long
Term Monitoring Plan for the past year I do not believe a mercury limit is warranted.
Based on the results of the South Fork Catawba River Water Quality Alliance Color
Study, I believe that continuing the collection of data, using the Study collection
points, through a quarterly monitoring process is all that is warranted. The Study
showed that color is not a contributor to pollution in the South Fork.
From the Office of the Director

dissipates after completely mixing in the stream. Mixing zones, where water quality standards
do not apply, are allowable under EMC rules, provided that unsightly conditions do not result
within the mixing zone.
6.5 RECOMMENDATIONS
Based on the results of the study, we recommend continuation of a monitoring program for
ADMI color on a less intensive basis. We make no specific recommendations on a facility -by -
facility basis.
6.5.1 Quarterly ADMI Color Monitoring
A significant database of information has been developed from the April - November
2000 sampling program. It is recommended that continuation of a collective,
coordinated sampling program be performed on a quarterly basis. A coordinated
instream sampling program will provide a more consistent, meaningful and reliable
database of ADMI color in the river than that which could be obtained from individual
monitoring, and it will supplement and continue the database begun under the color
study. Working from the baseline begun during the color study, continued monitoring
can be performed quarterly on a less intensive basis and still provide valuable and
coherent data from which changes can be detected.
The proposed plan for quarterly monitoring is presented in Appendix E. It is
recommended that ADMI monitoring be performed on effluent samples from each
Alliance discharger and from seven selected river locations, as discussed in the

SUMMARY OF FACILITY INFORMATION AND WASTELOAD ALLOCATION
Because of the number of textile mills that discharge into the Lincolnton WWTP, there
has been a complaint about its colored discharge into the South Fork Catawba River. A
public hearing on the renewal of the permit has been requested by the Catawba River
Foundation and will be held August 28, 2001.
The City of Lincolnton has requested a permit renewal for the Lincolnton WWTP. The existing
6.0 MGD WWTP discharges into the South Fork Catawba River, a class WS-IV water, in CTB35
subbasin. The discharge is three miles upstream of the City of High Shoals drinking water
intake. The plant serves a population of approximately 10,300 people.
The Lincolnton WWTP is an existing 6.0 MGD wastewater treatment facility consisting of a bar
screen, dual grit chambers, three primary clarifiers, three screw pumps, a flow splitter box,
four diffused aeration basins, three trickling filters, four secondary clarifers, three 250,000
gallon anaerobic sludge digestors, three 250,000 gallon sludge storage tanks, three chlorination
contact basins, and 68 sludge drying beds.
Lincolnton currently has an active pretreatment program with Long Term Monitoring Program.
There are nine significant industrial users (SIU) discharging to the system. The facility has an
average industrial flow of 2.15 MGD. The permitted industrial flow is 2.68 MGD.
SIUs - for Lincolnton WWTP are as follows:
• ALPHARMA - pharmapheutical products - 0.050 MGD - continuous flow
• FABRICTEX- high-tech knits. cotton and synthetic fabric - 0.150 MGD- continuous flow
• HAWORTH - office furniture - 0.015 MGD - continuous flow
• MCMURRAY FABRICS - intimate apparel, industrial and military type fabrics - 0.300 MGD
- continuous flow
• MOHICAN MILLS.- knitted textile fabric - 1.317 MGD - intermittent flow
• SOUTH FORK INDUSTRIES - dyed and finished fabric - 0.552 MGD - continuous flow
• TEXTILE PIECE DYEING COMPANY, INC. - textile finisher - 0.278 MGD - continuous flow
• VIKING TECHNOLOGY, INC. - socks - 0.025 MGD - continuous flow

The South Fork Catawba River is not listed on North Carolina's 2000 303(d) list. The use
support rating for 7.2 miles of the South Fork Catawba River, where the Lincolnton discharge
is located, from Clark Creek to 0.3 mile upstream of Muddy Creek is fully supporting but
threatened. The major source is point with the possible source listed as Clark Creek. The
biological assessment of the South Fork Catawba River at NC 27 (Lincoln County) in September
1994 was Good. The biological assessment was Good -Fair at the next downstream South Fork
Catawba River station at NC 7, McAdenville, Gaston County which was evaluated in August
1997.
TOXICITY TESTING:
Current Requirement: Chronic Toxicity P/F @ 11%; March June September December
The Lincolnton WWTP has consistently passed the toxicity test since 1996. Only one FAIL
(March 1997) test has occurred in past four years. One No Report in Dec. 2000 but test was
submitted during that month. All other test results have been PASS.
Recommendation: Renewal of existing chronic toxicity test @ 11%.
REASONABLE POTENTIAL ANALYSIS:
Analysis was conducted using daily monitoring report data from 1998, 1999, and 2000 and
pretreatment Long Term Monitoring Data from 1999 and 2000. The parameters that were
analyzed were arsenic, cadmium, chromium, copper, cyanide, lead, mercury, nickel, selenium,
silver, zinc, and phenolics.
• It was determined that a reasonable potential existed for cyanide, mercury, and phenolics
to exceed the water quality standard. Daily maximum limits were assigned for these three
parameters.
• It was also determined that copper had the reasonable potential to exceed the NC action
level. It is recommended that monitoring be increased to 2/month per 15 NCAC 2B .0500.
• While the analysis for zinc did not show reasonable potential to exceed the state action
level, it was recommended that monthly zinc monitoring be continued because of concern
for zinc discharges and potential toxicity from municipalities
• Cadmium no longer showed the reasonable potential to exceed the NC standard and
therefore the existing limit can be deleted. Effluent monitoring will be reduced to 2/month.
COMPLIANCE SUMMARY:
Through April 2001, Avg. Qw = 3.3 MGD (approximately 55% of capacity), BOD5=13.5 mg/1,
NH3=7.3 mg/1, TSS=18.5 mg/1, TN=9.5 mg/ and TP=2.08 mg/1.
In 2000, Avg. Qw = 2.7 MGD (approximately 45% of capacity), BOD5=15.0 mg/1, NH3=11.9
mg/1, TSS=20.4 mg/1, TN=10.6 mg/ and TP=2.62 mg/1. One TSS violation in January and
one pH violation in December
Lincolnton WWTP Fact Sheet

In 1999, Avg. Qw = 3.05 MGD (approximately 51% of capacity), BOD5=13.0 mg/1, NH3=6.35
mg/1, TSS=16.6 mg/1, TN=7.7 mg/ and TP=1.51 mg/1.
In 1998, Avg. Qw = 3.27 MGD (approximately 55% of capacity), BOD5=12.5 mg/1, NH3=3.52
mg/1, TSS=14.7 mg/1, TN=9.8 mg/ and TP=2.32 mg/1. One flow violation in February and
one pH violation in December
In 1997, Avg. Qw = 3.49 MGD (approximately 58% of capacity), BOD5=13.5 mg/1, NH3=6.16
mg/1, TSS=17.3 mg/1, TN=12.6 mg/ and TP=2.4 mg/1.
INSTREAM MONITORING:
Facility does not have instream monitoring at this time. Color issues must be addressed in the
South Fork Catawba River. Instream monitoring for color may be required per results of color
study.
PROPOSED CHANGES:
The following modifications have been made to the permit:
• The cyanide limit of 22 ug/1 (daily maximum) will be added to the permit based on results of
the reasonable potential analysis. The limit is based on the 1/2 FAV value for cyanide
• The mercury limit of 0.1 ug/1 (daily maximum) will be added to the permit based on results
of the reasonable potential analysis.
• The phenolics limit of 21 ug/1 will remain in the permit based on results of the reasonable
potential analysis.
• The cadmium limits (daily max. and weekly avg.) will be deleted from the permit based on
results of the reasonable potential analysis, which showed that the water quality standard
would not be exceeded instream. Will recommend that cadmium monitoring be reduced to
2/month.
• Effluent monitoring for copper will be maintained based on results of the reasonable
potential analysis. It is recommended that copper monitoring be increased to 2/month per
15 NCAC 2B .0500.
• Effluent monitoring for zinc will be maintained because of DWQ concern for discharge of
zinc from municipalities and potential effect on toxicity. It is recommended that monthly
zinc monitoring be maintained.
• Color monitoring and reduction requirements will be added based on results of AWARE
Environmental study.
This facility has been classified as a Tier 2 color discharger. The permittee will conduct
color monitoring of instream stations (upstream, downstream) on a monthly basis during
summer season (April -October). The permittee will record whether a color plume was
observed around the outfall pipe during the monthly instream sampling events, and include
that information on the monthly discharge monitoring report. Effluent samples will be
collected monthly for color on a year-round basis. Color samples will be analyzed for ADMI
color at natural pH. Effluent samples will consist of 24-hour composites, while instream
samples will be collected as grabs. Samples will be analyzed by a state certified laboratory.
The permittee will prepare a Pollution Prevention/Best Management Practices (BMPs)
report. This report will address the potential for the facility to reduce effluent color by
incorporating pollution prevention measures and/or BMPs prior to treatment. This report
could include an evaluation of the dyeing process, looking at the potential for dye
substitution, improving dyeing efficiencies, etc. The report could also investigate whether
any BMPs could be implemented that would reduce the amount of color discharged to the
treatment plant. The permittee could do this work independently, or request voluntary
assistance from the North Carolina Division of Pollution Prevention and Environmental
Assistance. The report will be submitted within 12 months of the permit effective date.
If data show that water quality standards for color are being violated by the discharge
permitted by the terms of this permit, then the Director may reopen this permit for the
purpose of imposing additional requirements pursuant to 15A NCAC 2H.0114.
Alternatively, if future conditions change and color is no longer a component of the influent
wastestream, then the permittee may request a permit modification to remove color permit
requirements.

1.0 INTRODUCTION
The City of Lincolnton is centrally located in Lincoln County, North Carolina and is
situated midway between the metropolitan Cities of Charlotte and Hickory, both of
which are experiencing dynamic growth patterns. The City of Lincolnton as defined
prior to 1989 experienced no increase in population over the past four decades; however,
the major annexation of an adjacent residential area known as Boger City in that year
resulted in a 40-percent increase in population with the population increasing from 4,879
in 1980 to 6,847 in 1990. The current population of the City of Lincolnton is 10,313.
The City owns and operates its own water and wastewater system serving residential,
commercial, and industrial customers both inside and outside the City Limits. The water
system consists of a 6.3-million-gallon-per-day (MGD) water treatment plant (WTP)
with raw water presently being obtained from the South Fork of the Catawba River. The
capacity of the plant is currently being expanded to 9.0 MGD.
The water distribution system delivers water to approximately 4,400 customers, 65
percent of whom reside within the City Limits. Outside customers include serving bulk
water to Lincoln County. The City of Lincolnton also simultaneously supplements its
own finished water with the purchase of bulk water from Lincoln County.
The wastewater system includes a collection system and a 6.0-MGD wastewater
treatment plant (WWTP) serving over 2,600 customers, 95 percent of who reside within
the City Limits. Although these facilities treat only a present 4.5 MGD on a daily
average, increases in regulatory requirements will necessitate major upgrades in
treatment processes within the near future. The present effluent permitted limits will
expire on July 31, 2000, and anticipated new limits will become significantly more
stringent. Future growth may also require some increases in capacity in the treatment
plant, together with additional collection system improvements.
The present WWTP requires significant alterations to meet anticipated limits. For
instance, major treatment process changes are required to meet the phosphorus and
nitrogen limit requirements. Disinfection improvements are also required, followed by a
dechlorination process.
Approximately half of the facilities within the WWTP are in excess of 30 years in age,
while the remainder has been in use for 16 years. In addition to the normal expected
maintenance, a number of items that require major repairs, replacement, or
refurbishment were identified in the 1995 Master Plan.
The existing administration facilities, particularly the laboratory, must be upgraded and
enlarged for adequate future management and operation.
Lincolnton WWTP NPDES Renewal

Page 4

The wastewater collection system serves the entire City with some minor service
extended outside the City Limits. The system consists of approximately 52 miles of
gravity sewer, ranging in size from six-inch diameter to 30-inch diameter. (This does not
include any service lines.) There are at present six major lift stations within the collection
system and a number of linear feet of force main ranging in size from four -inch diameter
to 16-inch diameter.
Increases in flow, up to twice the normal, occasionally occur within the WWTP during
periods of wet weather. Such flows are due to inflow/infiltration within the collection
system; however, this amount is not considered excessive and, for the most part,
inflow/infiltration is minimal.
The existing WWTP operates, for the most part, satisfactorily and meets its present
effluent limits. Treatment units within the plant are in need of refurbishment or
replacement due to normal wear and tear. Some of the equipment is aging and in need
of replacement.
The major deficiencies of the existing treatment facilities are that the overall process is
not capable of meeting anticipated future effluent standards. Meeting such standards
will require significant overall changes and modifications. In addition to these
requirements, new administration and laboratory facilities are also needed.
To meet pending mandatory effluent limits that are significantly more stringent than the
existing limits, immediate steps must be taken to provide an upgrade in the present
treatment processes.
Improvements for upgrading the plant include modifications that will significantly
upgrade the degree of treatment from a present secondary process to a more -advanced
tertiary process. The advanced processes to be added include biological nutrient
removal (BNR), nitrification and denitrification, phosphorus removal, filtration,
chlorination and dechlorination, and final effluent aeration. The processes for treating
and disposing of biosolids and side streams will also be upgraded. Proposed upgrades
include:
• New Anaerobic Digester Mechanical Mixing Systems
• New Gas -Holder Covers
• New Heater/Heat Exchanger Equipment
• New Dissolved Air Flotation Thickener
• New Solids Contact Reactor

2.0 EXISTING FACILITIES
The Lincolnton WWTP is a secondary treatment facility with a present capacity of 6.0
MGD. The plant was originally constructed in 1965 as a 3.0-MGD facility and was
expanded in 1981 to its present 6.0-MGD capacity. The major process units include
preliminary treatment, consisting of a coarse screen and grit removal; primary
treatment, consisting of primary clarification; secondary treatment, consisting of
roughing filters, aeration, secondary clarification, and chlorination; sludge handling,
consisting of anaerobic sludge digestion and dewatering of sludge by sand -drying beds.
In 1990, the City implemented a Sludge Land Application Program. The drying beds are
not presently used. The liquid sludge is hauled off for land application by a contracted
service.
The Lincolnton WWTP currently has NPDES Permit No. NC0025496 with the following

6.0 PROPOSED DESIGN
The proposed upgrades to the existing 6.0-MGD plant and alternate designs for
expansion to 9.0 MGD are described in the following section. A Flow Diagram of the
proposed system is attached as Figure 1. All wastewater treatment facilities are
protected from the 100-Year Flood. The 100-Year Flood elevation at the project site is
759. Required buffer zones from property lines and streams are provided for all newly
proposed wastewater treatment facilities.

6.2 MAIN LIFT STATION
The existing main lift station Pump Room contains five pumps. Pumps Nos. 1, 2, and 3,
were installed in 1965. Pumps Nos. 4 and 5 were installed in 1981. The pumps are
extended -shaft, vertical, non -clog sewage pumps. The suction size on Pump No. 1 is 4";
No. 2 is 8"; No. 3 is 10" and 14" on Pumps Nos. 4 and 5. The main lift station is a
reinforced concrete structure with a masonry superstructure. The finish -floor elevation
for the pump station is 762.50 feet, which is 3.5 feet above the 100-year flood elevation of
759 feet.
The existing main lift station will be upgraded by replacing the existing pumps. Four
new close -coupled, vertical, non -clog sewage pumps will be added to provide adequate
pumping capacity for the peak influent flow. Instrumentation and controls will be
provided for starting/stopping and sequencing the operation of the new pumps. Pump
speeds will be variable and controlled by variable frequency drives. Pump check control
valves will be electrically operated.

6.3 BNR (BIOLOGICAL NUTRIENT REMOVAL)
BNR will be utilized for the removal of COD, BOD, SS, Nitrogen, and Phosphorus. The
BNR process will be designed for nitrification and denitrification and phosphorus
removal, utilizing anaerobic; axoxic and oxic zones; intemal recirculations of the MLSS;
and external return of the activated sludge.
The process will utilize the Orbal Aeration Process. A new two -channel Orbal basin will
be constructed to treat an average daily flow of 6 MGD with provisions for an alternate
third channel to treat an additional 3-MGD flow. The existing aeration basins will be
modified and retrofitted with fine -bubble aeration.
The BNR process design is based upon a 6.0-MGD initial flow condition and a 24-
lb/1000 cf BOD loading. The design utilizes two -channel Orbal oxidation ditch
preceding the existing aeration basins, the first channel of the Orbal being used for
sludge reaeration. The Orbal will have four 50-HP aerators with the drives on the center
island.
Detention time will be 15 hours. Solids concentration will be 7,000 mg/1 in the sludge
reaeration channel and 3,500 mg/1 in the rest of the system. Resulting sludge age will be
15 days. It will be possible to operate at lower sludge ages; a ten-day sludge age may be
more desirable for reducing aeration power costs and increasing performance of the
anaerobic digesters. Thus, in actual operation —at the 6.0-mg flow condition —the
operating MLSS levels might be closer to 6000/3000 mg/1.
The altemate expansion will be based upon adding a third 20-foot-wide channel and six
25-HP disc aerator assemblies. At full design flow, the loading will be slightly greater
than 24 lbs/1000 cf. The design is based upon a 15-day sludge age with an MLSS split of
8000/4000 mg/1.
The expected power draw is as follows:
6.0 MGD: 197 bHP
9.0 MGD: 303 bHP

filters. The objective of the filtration process will be to remove additional nutrients and
suspended solids so that the effluent will consistently meet the NPDES effluent limits.
Filters are sized based on a nominal filtration rate of 2.0 GPM/SF. Multiple filter cells are
used to allow one filter to be taken out of service for repairs, maintenance, or
backwashing without impacting the performance of the system. Backwashing will be
accomplished by a combination of air scouring and water backwashing. Water for

bottoms, media, and other appurtenances will be installed in six cells for the upgrade.
The two additional cells will be completed for the alternate expansion.
6.9 DISINFECTION
Chlorination and dechlorination will be utilized for disinfection. Disinfection is to be
achieved through the application of a sodium hypochlorite (chlorine) solution injected
into the wastewater in an open contact chamber. Sodium bisulfite will then be
introduced into the chlorinated effluent to provide dechlorination.
The contact tank is designed for a nominal contact time of 30 minutes.
The sodium hypochlorite (chlorination) system will be comprised of two 10,000-gallon
FRP or polyethylene storage tanks, transfer pipe and appurtenances, metering pumps,
recirculation pumps, safety equipment, and associated filling station and transfer
controls.
The sodium bisulfite (dechlorination) system will be comprised of two 5,000-gallon FRP
or polyethylene storage tanks with transfer pipe and appurtenances, metering pumps,
recirculation pumps, safety equipment, and associated filling station and transfer
controls.
The sodium hypochlorite and sodium bisulfite will be stored in storage tanks which will
be equipped with support structure, manway, ultrasonic level meters, pressure relief,
discharge, vent, recirculation, distribution and overflow connections.
At the storage tanks, the sodium hypochlorite (12.5% concentration) and sodium
bisulfite (30% concentration) is mixed with water to form a 5.25% solution and up to
30% solution, respectively, that is metered/pumped to the effluent where it is diffused
into the effluent.

The existing anaerobic digester system is comprised of six 45'-0"diameter x 27'-1" SWD
concrete tanks each with a volume of approximately 327,000 gallons. Three of the
digester tanks are used for primary anaerobic digestion and three tanks are used for
storage of digested sludge. The digester tank and control building structures are in
serviceable condition. The three primary digestion tanks have floating covers, each with
a Perth gas -mixing system. The existing system also includes two sludge heat
exchangers, one 180,000 btu/hr capacity (circa 1984) and the other approximately
300,000 btu/hr capacity (circa 1965). The sludge heating equipment is undersized for the
expansion and does not work properly. As well, the gas mixing systems are currently in
disrepair and do not provide mixing.
Lincolnton WWTP NPDES Renewal
2000013
Page 26

Also, there are six sludge pumps —four 15-hp and four 5-hp—used to transfer sludge
into and out of the system and between the digesters and the sludge heat exchangers
respectively. Two 15-hp horizontal non -clog pumps circulate raw and recirculated
sludge (low solids concentration) into and between the digesters. Four 5-hp horizontal
non -clog pumps (two in operation at a time) circulate sludge (low solids concentration)
between the digesters and the sludge heat exchanger. As well, two 15-hp plunger -type
displacement pumps are used for transferring digested sludge (high solids
concentration) out of the system or between the tanks. The sludge transfer system is
installed with pumps in parallel and with isolation valves to allow for flexibility of
operation should one or more pumps be out of service. The existing ductile iron pipe
network appears serviceable; however, all pumps need to be replaced due to increased
performance requirements.
A supernatant liquor piping system for sampling and recycle, is serviceable; however, a
single -point rotating remover will be installed in the three storage digesters for ease of
supernatant removal, inspection, and sampling. All supernatant liquor sampling and
transfer pipe, fittings, valves, and appurtenances in the existing digesters and digester
control building should be inspected to determine if continued use is possible. All
suspicious piping or components should be replaced and the system reassembled and
painted.
All pipe and gas safety equipment in the digester gas collection system is unserviceable,
due to excessive corrosion, and needs to be replaced.
All three floating covers need to be replaced along with all ancillary equipment because
of corrosion damage and disrepair.
Design Criteria
The following criteria were used to evaluate digester -tank residence time, sludge -mixing
power, sludge -heating requirements, and gas -safety equipment sizes.
Plant Influent: 6.0 MGD
Average Solids Loading for Digester Sizing: 12,000 lbs/day
Sludge flow into digesters for digester sizing: 36,000 gal/day
Percent Volatile Solids: 60%
Percent Volatile Solids Destroyed: 50%

•
Meet anaerobic digestion process requirements to significantly reduce pathogens in
accordance with EPA Part 503 Biosolids Rule. Values for the mean cell residence time
and temperature shall be between 15 days at 95° F to 60 days at 68° F.
Required Expansion and Repair of Existing Facilities
At an influent flow rate of up to 9.0 MGD, the existing six digester tanks can be utilized.
Three digester tanks are used for primary anaerobic digestion and have new floating
covers. One digested sludge storage tank has a rigid gas -holder cover, capable of storing
10,800 cubic feet (cf) of digester gas at 11 inches of water column pressure (iwc) when
the digester tank is at maximum sludge -holding capacity. Gas -holder tank gas volume
varies with sludge volume. The remaining two tanks are uncovered and are also used to
store digested sludge. Each digester tank has a volume of approximately 327,000 gallons.
At 6 MGD, based on a sludge flow rate of 12,000 lbs/day (36,000 gal/day at 4% solids
concentration) the three anaerobic digester tanks have a 27-day mean cell residence time.
Sludge temperature will be maintained at 95 ° F. In addition, based on a digested sludge
flow rate of 8,400 lbs/day (16,787 gal/day at 6% solids concentration), the three storage
tanks have the capacity to retain processed sludge for 58 days at influent design capacity
of 6 MGD. Total digester tank hydraulic residence time is 85 days, before transfer to
land application sites or to existing sludge beds is necessary.
Mixing of the primary digesters will be accomplished by a vertical, mechanical -mixing
system, which will vigorously and homogeneously mix sludge throughout the digester
tank. Mixing of the tank contents will optimize digester performance capacity and gas
production. Correct mixing assures that:
• the food supply is uniformly dispersed;
• the incoming sludge is in constant contact with the growing cells to promote
maximum utilization of the system;
• the concentration of biological end products is kept at their lowest value by
dispersing them uniformly throughout the digester;
• incoming sludge and nutrients are uniform throughout the digester allowing the
best possible cell development;
• toxic materials entering the system are quickly dispersed, minimizing their effects on
the anaerobic process;
• dispersion of floating solids prevents a scum layer built up on the top of the digester
tank;
• The temperature of the tank contents remains uniform.

The existing digesters have compressors and control equipment enclosed in housing and
mounted on the digester cover. The new mechanical mixers will be mounted vertically
outside and on the periphery of the three primary digesters. At each location, two 39-
inch-diameter inlet and outlet pipes penetrate the digester walls connecting the tank
with the mixer body and propeller.
All sludge transfer pipes, fittings, and valves in the existing digesters and digester
control buildings should be inspected to determine if continued use is possible. All
unserviceable piping or components will be replaced.
Replace the two existing 15-hp horizontal non -clog pumps with new 30-hp pumps for
circulating raw and recirculated sludge into and between the digesters. As well, replace
the four existing 5-hp horizontal non -clog pumps with four new 7.5-hp pumps for
circulating sludge and raw sludge between the digesters and the sludge heat
exchangers. Replace the two 15-hp plunger -type positive displacement pumps with two
50-hp progressing cavity pumps for transferring digested sludge.
Interface updated controls and instrumentation with the existing SCADA System for
sludge heating and digester sludge pumping semi -automation.
Methane Production/Storage/Usage
At the estimated solids production rate, the plant has the potential to produce up to
2,250 cubic feet per hour of methane. This converts to an available energy source for
approximately 1,350,000 BTU's per hour. This digester gas will be used as fuel to fire the
sludge boilers. The sludge boilers are required to maintain the anaerobic digester tanks
at 95° F in order to comply with requirements for mean cell residence time. Sludge
boiler(s) operate periodically based on requirements to heat the incoming sludge and
maintain digester temperature.
The following is a summary of the condition and recommended improvements:
The 1965 and 1984 sludge heat exchangers are located in the heat exchanger building
(Building. 900). The units were evaluated and determined to be significantly under
capacity for the new expansion requirements. Based on heat transfer review, a
combination of sludge boilers with a total heating capacity of 1,500,000 Btu/hr is
required for winter operation. As a result, sludge heating will be accomplished by
replacing the existing sludge boilers (combined capacity of approximately 500,000
Btu/hr) with two new 750,000 Btu/hr sludge boilers. The new sludge boilers primary
fuel will be digester gas with natural gas as a backup. Controls will be included to
ensure maximum digester gas usage, blending digester gas with natural gas and to meet
new code requirements. The heat exchanger building will also be modified adding new
access doors to facilitate installation and servicing. Note: The digester gas demand for
one 750,000 Btu/hr sludge boiler is approximately 1,500 cf/hr.

There are three existing Duo -Deck steel covers on Digester Tanks No. 2, No. 3, and No.4;
and each cover has a Perth gas recirculation unit. Rusting is evident on the roof plates,
plate seams, and roof access ports. The Perth units have been severely neglected and are
beyond use. We recommend that the three existing floating covers be replaced with
three new steel floating digester covers. The new covers will be welded, single -shell
construction with sidewall skirt and insulation. The covers will allow for varying liquid
levels in the digester while maintaining a constant internal gas pressure and minimizing
gas leakage. In addition, one steel floating gas -holder cover will be installed on Digester
Tank No. 1 and designed to hold approximately 10,800 cubic feet of digester gas. The
gas -holder cover will also be welded, single -shell construction with long sidewall skirt.
In addition, the floating gas -holder cover will be installed with vertical guide rails for
wind -load stability. All new covers will have new gas safety equipment,
access/sampling hatches, guide rail components and ballast.
As well, for Digester Tanks No. 2, No. 3, and No. 4, the Perth gas recirculation units will
be replaced with 15-hp, externally -mounted, vertical -mechanical sludge mixers with
non -clogging propellers. The mixers are simple technology, low maintenance, and
mounted externally to the primary digesters for ease of maintenance. Each mixer is
capable of circulating the contents of a primary digester, through the mixer, in less than
20 minutes. This will provide a high mixing rate, resulting in local uniformity of mix,
and maximum digester gas generation.
Recommendations for modifications to the gas system are as follows:
• The gas safety system should be completely replaced. All existing ductile iron pipe
should be replaced with Type 316L stainless steel Schedule 10 pipe.
• All in -line devices for the gas safety system will be replaced. New accumulators,
drip traps, flame arresters, and check valves will be installed for Tanks No.1, No. 2,
No. 3, No. 4, the waste gas burner, and the heat exchanger boiler lines.
• The existing orifice meters and local flow and temperature recording equipment will
be removed. Low-pressure transmitters will be added to augment manometer
pressure readings. In -line flow Venturi with associated differential pressure
transmitters will be installed to monitor digester gas flow. Digester temperature
probes will be inspected and replaced if unserviceable. New electronics will be
integrated into the existing SCADA System.
• The existing waste gas burner will be replaced and the new burner will include
automatic operation and a natural gas pilot. As well, the existing pressure relief
valve to the waste gas burner will be replaced.

• There is an Envirex cover position system consisting of a cable -driven drum at the
top of the wall with a sealed sensing system down to an indicator box with alarms.
Only the cable and pointer systems appear to be working. The cover position
indicator equipment will be inspected and replaced as necessary. Primary cover
indication will be provided using ultrasonic level transmitters mounted on the
floating covers or digester tank side walls and integrated with the SCADA System
for display in the control room.
• Manometers — The existing manometer assemblies can be fairly easily rehabilitated.
The following items of work are included in the plans:
• Replace Pepcocks
• Provide new Glass Tubes and Gaskets
• Repipe all Sensing Lines from their Respective Sources
Sludge Holding Tanks No. 5 and No. 6 will be uncovered and unheated and will be
utilized to store digested sludge which is to be disposed of by land application.
6.12 DISSOLVED AIR FLOTATION (DAF) SLUDGE THICKENING
Thickening of the waste -activated sludge prior to anaerobic digestion is included in the
upgrade because it offers the following benefits:
• Reduction in the size of all downstream processes;
• Reduction in the volume of the sludge entering the digester;
• Reduction of all downstream power requirements;
• Provides the means for hydraulic control of the sludge, thus providing better
operation of downstream processes;
• Reduces the amount of supernatant to be handled from the anaerobic digesters.
DAF thickeners provide high -solids concentrations important to successful digester
operation. The DAF System utilizes microscopic air bubbles to float solids to the surface
of the tank. Bubbles have a compacting effect on the sludge particles and form a sludge
blanket denser than that formed in conventional gravity thickeners. Sludges with
normal solids contents of 0.5 to 1.0 percent can be thickened to a 3-to-5 percent solids
content.
Lincolnton WWTP NPDES Renewal
2000013
Page 31

The DAF Process is particularly well suited for use in conjunction with anaerobic
digesters. DAF units tolerate wide variances and hydraulic loads, while maintaining a
consistent predictable solids concentration. This feature reduces the possibility of
hydraulically overloading the digesters. The DAF also acts as a secondary grit removal
facility eliminating grit accumulation in the digesters and reducing expensive digester
cleanouts. The continuous withdrawal of thickened sludge from the DAF unit provides
a uniform feed of sludge to the digester throughout the day enhancing the overall
digester performance.
The DAF thickener had the added benefit of providing a source of oxygen to the
phosphorus -laden waste activated sludge, thereby keeping the phosphorus concentrated
in the sludge. Since phosphorus must ultimately be removed through the sludge solids,
it is preferred that the phosphorus not be released until the sludge is in the digester.
DAF units may be constructed in either rectangular or circular configurations. We
recommend a rectangular unit.
The DAF design parameters are as follows:
Total Number of Basins 2 Each
Effective Length 65'-0"
Effective Width 12'-0"
SWD 9'-0"
Net Solids Load - Solids Produced 500 lbs/hr
Capture Rate (Efficiency) 85%
Gross Solids Load - Solids Fed to Unit 588 lbs/hr
Pressured Flow 415 gpm
Air Flow Rate 4.0 SCFM
The DAF thickening system is designed to operate for 24 hours per day, seven days per
week, and produce 84,000 lbs/week solids.

6.13 SOLIDS CONTACT REACTOR (SCR)
In the Biological Nutrient Removal (BNR) portion of this facility, phosphorus is removed
from the system as a fixed biological material in the waste sludge. The phosphorus -
laden waste ultimately ends up in the anaerobic digester. With the absence of oxygen in
the anaerobic digester, a portion of the phosphorus is released from the sludge into the
digester supernatant.
The digester supernatant is recycled to the BNR facilities for treatment. The
supernatant, if not conditioned to remove the phosphorus which was released in the
digester, would return the phosphorus back to the BNR system where it was initially
removed; therefore, it is necessary to provide a system for treating the supernatant from
the digester prior to returning the supernatant to the BNR facilities. A solids contact
reactor system will provide the necessary treatment. The solids contact reactor removes
the phosphorus that has been separated from the liquid waste stream by chemical
conditioning. Conditioning chemicals such as alum or polymers are combined with the
supernatant. Mixing is applied, and the flocculated solids that contain the phosphorus
are allowed to settle. The phosphorus -laden solids are withdrawn and returned to the
anaerobic digester. The reactor overflow is returned to the BNR facilities.
