Subject: Issuance of NPDES Permit NCO025071
Mebane Bridge WWTP
Rockingham County
Dear Mr. Asbury:
Division of Water Quality (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).
The following changes have been made to the draft version of your permit:
• As noted in your comments, the facility address has been corrected to 204
Mebane Bridge Road.
• As a result of comments from the US EPA Region 4, an ammonia reopener
condition has been added to this permit. This condition specifies that a weekly
average ammonia limit may be added to this permit after a reasonable potential
analysis of effluent ammonia data.
• The required percent removal for total suspended solids (TSS) has been changed
to 85%. It appears that your facility is capable of meeting this monthly average
requirement on a regular basis. As such, the Division does not believe that the less
stringent 75% removal requirement is necessary.
• In response to the new NPDES municipal application data requirements, DWQ is
reinstating annual effluent pollutant scans into municipal permits. Special
Condition A. (3.) of this permit details this requirement. Be advised that pollutant scan
data must be submitted on the Discharge Monitoring Report Form for the appropriate
month. Upon renewal of this permit, the City of Eden should use this data in
completing application 2A.
In addition, please note that there are endangered species present in the receiving
stream for your discharge. The North Carolina Wildlife Resources Commission has
recommended stand-by power (if not already in place) and alternatives to chlorination in
order to protect these species. Furthermore, be aware that North Carolina is in the
process of adopting a new standard for total residual chlorine. It is anticipated that this
standard will be 17 µg/L. Such a limit would be implemented at the time of your next
permit renewal.
If any parts, measurement frequencies or sampling requirements contained in this
permit are unacceptable to you, you have the right to an adjudicatory hearing upon

written request within thirty (30) days following receipt of this letter. This request must be
in the form of a written petition, conforming to Chapter 150B of the North Carolina
General Statutes, and filed with the Office of Administrative Hearings (6714 Mail Service
Center, Raleigh, North Carolina 27699-6714). Unless such demand is made, this decision
shall be final and binding.
Please note that this permit is not transferable except after notice to the Division.
The Division may require modification or revocation and reissuance of the permit. This
permit does not affect the legal requirements to obtain other permits which may be
required by the Division of Water Quality or permits required by the Division of Land
Resources, the Coastal Area Management Act or any other Federal or Local governmental
permit that may be required.

Notes:
1. Sample locations: Upstream - Upstream at NCSR 1964; Downstream - Downstream at NCSR 700. Upstream and
downstream samples shall be grab samples. Stream samples shall be collected three times per week during June.
July, August and September and once per week during the remaining months of the year.
2. The monthly average BODs and TSS concentrations shall not exceed 15% of the respective influent value (85% removal).
3. The Division may re -open this permit to require weekly average limits for ammonia. After calculating allowable
concentrations, the Division will perform an analysis of past ammonia data to determine if there is a reasonable potential
for this discharge to exceed these potential limits. If there is, this permit will be re -opened. If there is not, the permit will
not be re -opened, but will contain weekly average limits for ammonia upon renewal.
4. The pH shall not be less than 6.0 standard units nor greater than 9.0 standard units.
5. Chronic Toxicity (Ceriodaphnia) P/F at 5.1%. Toxicity testing shall be performed in the months of March. June,
September and December (see Part A.(2.).
6. Sampling for zinc should coincide with sampling for chronic toxicity test.
T. Limit is an instantaneous maximum (i.e. not to be exceeded at any time) not a daily maximum.
There shall be no discharge of floating solids or visible foam in other than trace amounts.

Permit NCO025071
A. (2.) CHRONIC TOXICITY PERMIT LBUT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration- of 5.1%.
-The permit holder shall perform at a minimum, auarteriu monitoring using test procedures outlined
in the "North Carolina Cerkx1aphnia. Chronic Effluent Bioassay Procedure," Revised February 1998,
or subsequent versions or "North Carolina Phase., IL 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 code TGP3B for the pass/fail results and THP313 for the Chronic Value. Additionally, DWQ
Form AT-3 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality
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.

Dear Ms. Sierra:
Thank -you for the opportunity to review the draft wastewater discharge permit for the
City of Eden, in Rockingham County, North Carolina. The discharge from the facility is
to the Dan River, at approximately 23 river miles upstream of the public water supply raw
water intake serving the City of Danville. Due to the distance upstream, we have no
objection to the permit as drafted by the Division of Water Quality.

Natalie,
After review of the Mebane Bridge Draft Permit, we have only a couple of comments.
1. The plant address on the cover page shows 191 Mebane Bridge Road. The plant's
physical address is 204 Mebane Bridge Road. The incorrect address is also located on
the Supplement to Permit Cover Sheet.
2. We are confused on sampling frequencies for the Upstream and Downstream
locations. The confusion is because of the notation beside the Downstream location
and not the Upstream. We would assume that the notation was meant for both Up and
Down. We need some clarification on these locations and frequencies.
If you need any additional information concerning this matter, please feel free to
contact me at 336-623-9921 ext. 320.
Thanks,

Habitat Conservation Program
DATE: 22 April 2002
SUBJECT: Proposed Permit Renewal for Eden, City -Mebane Bridge WWTP, Rockingham
County, NPDES Permit No. NCO025071
Biologists with the North Carolina Wildlife Resources Commission (NCWRC) have
reviewed the subject application for impacts to fish and wildlife. Cur comments are providod is
accordance with provisions of the Clean Water Act of 1977 (as amended), the Fish and Wildlife
Coordination Act (48 Stat. 401, as amondad; 16 C.S.C. 661-667d), and North Carolina General
Statutes (G.S. 113-131 et seq.).
The applicant has submitted a request for a permit renewal for the Eden, City -Mebane
Bridge Wastewater Treatment Plant to discharge treated wastewater into the Dan River in the
Roanoke River basin. It is our understanding that this plant utilizes chlorine in their treatment
system. Chlorine is acutely toxic to aquatic organisms and forms secondary compounds that are
also detrimental to aquatic life. In addition, the dechlorination agent, hydrogen disulfide, is also
very toxic to aquatic life. We are especially concerned with impacts of this project on the many
sensitive species that are found in this system. The Dan River and its tributaries support a high
diversity of aquatic organisms, including largemouth bass (Micropterus salmoldes), sunfishes,
catfishes, minnows, darters, and mussels and other invertebrates. The Dan River aquatic habitat
is considered by the Natural Heritage Program to be a State significant natural heritage area, and
the Non -Game Section of the NCWRC has identified this river as one of six High pnonty areas
for long term conservation. There are records for the existence of the federal and state
endangered James River spinymussel (Pleurobema collina), the federal species of concern and
state endangered, green floater (Lasmigona subviridis), state species of special concern,
rivenveed darter (Ctheostoma podostemone) and bigeye jumprock (Scartomyzon ariommus), and
the state signi ficantly rare, Roanoke hogsucker (Hypentehum roanokense) and notched rainbow
(Villusa constricts) in the Dan River system.
We recommend that the following conditions be incorporated into the permit to reduce
impacts to fish and wildlife resources and in particular to listed species.

1. We request that ozone or ultraviolet light systems replace the chlorine systems. These
disinfbetants also provide an additional benefit of removing a hazardous material from
the workplace.
2. If not already in place, we suggest the installation of a stand-by power system.
Thank you for the opportunity to provide input during the planning stages for this project.

Hello, All -
I'm passing along this response from Marshall for you to add to your files.
[I've added names so you can tell who wrote what.] The string began with
Natalie asking Marshall about application monitoring requirements for Eden
and related issues.
This part focuses on how many PPAs we have to get before we issue this
permit. He's agreeing that we can move ahead with fewer than the required
number of samples so long as the other analyses are done after the permit is
issued. In explaining his rationale, Marshall contradicts himself, but I
don't have time to pursue this any further today.
Somewhere in the middle of the string, I mentioned the idea of adding app
monitoring requirements to the muni permits and asked if that sounded okay;
got no direct response. (See Natalie for the rest of the string, I already
deleted mine.)

yesterday w/o A/C wasn't good, but in our old building, we really had
some bad days. thanks for asking.
To clarify what I was thinking, they need to get "the rest of the data"
to have a complete application for the current renewal. Otherwise, the
current application would be incomplete and the regs wouldn't be met.
We are taking a similar approach with other states. I just reviewed a
FL POTW permit and have told them EPA is going to object if the permit
doesn't require that at least 3 samples that reflect seasonality be
collected for all Form 2A parameters.
the appproach you outlined re annual monitoring for hardness and oil and
grease sounds ok to me. For yrs, KY has required quarterly monitoring
of 4 metals and hardness for POTWs. I think we'd like to hear more
about what you want to accomplish and how you want to get there. We can
discuss this in more detail when we come up for the midyear.
let me know if you need anything else. Marshall

Natalie - This is my draft response to Marshall's last message. Would
you see if this makes sense to you before I send it?
Let me see if I understood you on the 2A question: With one PPA in hand
(forget the other testing for now), we can issue Eden's permit. Then we
require them to do the other 2 PPAs (seasonally) early in the next
permit term. So we can say they met the application requirements for
the permit we already issued?
If that's the idea, wouldn't it be more above -board to just say, "Look,
we have a problem here. NC has only recently begun to implement the
municipal application requirements adopted in '99. (Bad NC! Bad!) The
new monitoring requirements, which take about a year to complete prior
to application, have not been met. They will be met for those
applications due in a year or more. Permittees submitting applications
in the meantime don't have enough time to perform all of the monitoring
but will complete as much as is reasonable and meaningful. It's an
awkward situation and we're doing the best we can with it."
True, these 'interim' applications won't fully meet the federal
requirements. The deficiencies are significant but not critical to the
resulting permit. Remember, we required PPAs in years past (before my
time here) and saw so few 'detects' that we dropped the requirement. We
don't like not meeting the requirements any more than EPA does, but I
don't see a way around it unless we wait a year to get the monitoring
results (and we have enough backlog issues already).
As for what we want to accomplish, we want to make sure we meet the
requirements of the state and federal water quality programs. We just
thought it would be easier to add the pre-app monitoring requirements to
the permit rather than just rely on the permittees to remember them (and
have to deal with it when they don't).

Hi, Marshall -
Hope you're doing well down there - I understand yesterday's A/C failure
brought new meaning to the name 'Hot-lanta.'
< I certainly can agree with getting one sample now, which is appropriate,
but that does not absolve the permittee from getting the rest of the data
during the term of the permit, as the regs require. >
When you say they have to 'get the rest of the data,' do mean that they make
up the other tests for the current renewal? Or just that we need to make
sure they're doing it during the permit term for the next renewal? (BTW,
that's "make up" as in "make up the missed test," not "make up some numbers
to put on the DMR. <grin>)
We are considering adding PPAs and the 2nd species WET tests to the major
muni's standard monitoring requirements to make sure those tests are done
and the results available for each future renewal. We may also throw in
annual monitoring for other parameter listed in the form but not already
included in the permit - hardness and O&G are a couple that have come up.
Does this approach sound okay to you? Have any of the other states you're
familiar with come up with an approach we should look at?
Thanks. And stay cool down there.

1) The City did submit the new EPA Form 2A. Regarding Part D, a
minimum of 3 samples that address seasonality was not provided for
antimony, beryllium, thallium, all volatile organic compounds, all
acid -extractable compounds, and all base neutral compounds. The draft
permit does not require that this information be subsequently collected.
40 CFR Part 122.21(a)(2)(i)(B) and 40 CFR Part 122.21(j) require that
existing POTWs must provide the information required by Form 2A. EPA
recognizes that all this information may not be available at the time of
permit issuance. However, unless the draft permit is changed to require
that a minimum of 3 samples that address seasonality for all the
parameters and compounds cited above are collected and submitted within
12-18 months of permit issuance and unless the permit contains a
specific reopener that limits may be added based on evaluation of that
data, EPA will object to this permit for failure to meet the regs cited
above.
2. Re the 75% removal requirement for TSS, 40 CFR Part 133.103(d) does
allow for a lower percent removal for less concentrated influent
wastewater for separate sewers. This reg requires that in order to
receive such a lower requirement, the permittee must satisfactorily meet
3 separate criteria. The City's 5 pg. March 2002 rationale that was
provided with the draft permit materials does not address or meet
criteria #3, that the less concentrated influent wastewater is not the
result of excessive I/I. Because NC has not provided documentation that
all the requirements of 40 CFR Part 133.103(d) have been met, EPA
objects to the granting of a 75% removal requirement for TSS unless and
until the permittee submits adequate documentation that criteria #3 has
been met.
looking at the last 3 yrs worth of data that were submitted, it's
interesting that the overall avg is almost 88% and that the worst value
was really due to discharge problems. Because the City can meet this
most of the time, have you given any consideration to limiting the
amount of time that the 75% waiver would be allowed?
3) Based on the recent resolution of ammonia, it is our understanding
that this permit will include a reopener regarding weekly average
ammonia limits.
4) In Part A.1, the footnote for TSR references TSS. We recommend that
the two terminologies be consistent.
5) We had requested that the fact sheet contain a statement that this
facility will be required to implement its approved pretreatment
program. Will you add such a statement to the fact sheet?
6) Have you sent a copy of this draft NPDES permit to the State of
Virginia that may be affected by this discharge?

BACKGROUND
The City of Eden's Mebane Bridge WWTP (Class IV) has a permitted flow of 13.5 MGD. Actual
discharge has averaged 7.2 MGD over the last three years or about 55% of permitted capacity.
The permit was first, issued on June 9, 1997 and permit expires on February 28, 2002. The
Division received and acknowledged the appropriate documentation to renew on September 11,
2001. The facility serves the City of Eden (pop. 14,000), the town of Wentworth (pop. 2700)
and three Significant Industrial Users (SIUs). These SIUs are textile plants — National Textiles,
LLC, Santee Company, LLC, and Karastan Rug Mill — and are regulated through the City's
pretreatment program. Eden has a full Long Term Monitoring Plan (LTMP) with the Division's
Pretreatment Program.
The Winston-Salem Regional Office has conducted several inspections of the facility and
generally finds it to be well operated and maintained with few problems relating to the point
source discharge. There are, however, some concerns over sewer overflows at some of the pump
stations, one of which is the subject of a current enforcement case. The 2001 Roanoke River
Basinwide Water Quality Plan makes no recommendations for this facility and describes this
portion of the Dan River as generally being in good condition.
Instream Monitoring and Verification of Existing Conditions and DMR Data Review
This facility discharges to Dan River (classified C waters) in the Roanoke River Basin. Instream
data for 1999-2001 were reviewed for this permit renewal; the facility monitors downstream
temperature, dissolved oxygen, pH, conductivity and color in accordance with the NPDES
permit. Instream dissolved oxygen concentrations were generally fairly high both upstream and
downstream of the discharge, with the lowest value — 6.3 mg/L — well above the instream
Fact Sheet
NPUFSS \C0025071 Renewal
Fa,,c I

standard of 5 mg/L (the average instream dissolved oxygen concentration was 9.0 mg/L).
Temperatures and pH values appear seasonally appropriate and within acceptable ranges.
Conductivity increased to varying degrees downstream of the discharge but downstream values
seem reasonable. Color, probably the most significant instream parameter for this particular
permit, does not increase downstream by any significant amount. In some case, downstream
color was less than upstream. Overall, downstream color remained close to ambient (as
measured by upstream) - the highest value was 87 ADMI.
Discharge Monitoring Report (DMR) data from January 1999-November 2001 were also
reviewed. The facility monitors effluent flow, color, DO, BOD, Total Suspended Solids (TSS),
temperature, total nitrogen, total phosphorus, ammonia nitrogen, fecal coliform, copper, zinc and
total residual chlorine. The values for most of these parameters are summarized below; ND

The facility has experienced some problems with TSS (see Correspondence section below). The
average TSS value was 11.79 mg/L, but effluent values went as high as 78.9 mg/L. Ammonia
nitrogen levels are fairly low, with an average of 0.24 mg/L and values ranging from non -detects
to 1.36 mg/L. Effluent nutrient levels also look reasonable for this type of plant.
Total residual chlorine (TRC) values are fairly low -- average TRC was 1.38 ug/L with values
but the detection level used should be more sensitive. Cover language will be included to
address this. The facility has passed each quarterly toxicity test in the permit period.
Correspondence
The Winston-Salem Regional Office (WSRO) performed one compliance evaluation inspection
and one compliance sampling inspection during this permit term. The facility is generally
described as well maintained and operated.
Three NOVs have been issued during this permit term, all for violation of total suspended solids
limits. Civil penalties were assessed for two of these violations (June 2000 and September
2001), both of which were paid to the Division.
In January 2002, the Non -Discharge Compliance Unit assessed civil penalties for a sewer
overflow from the Railroad pump station in June 2001. An estimated 194,000 gallons of
wastewater wound up in Dry Creek and DWQ staff observed dead fish and blackish purple water
in the creek. The case is pending, but the regional office has been recommending that the facility
address the problem since a 1999 compliance inspection report.
The last staff report was submitted prior to the 1997 permit renewal.
PERMITTING STRATEGY
Waste Load Allocation (WLA). The Division prepared the last WLA in August 1996. The
previous and current effluent limits were based on guidelines and water quality standards. Limits
were recommended for BOD, TSS, ammonia nitrogen (summer only), total residual chlorine,
fecal coliform, pH and color. This WLA presented updated flow data, also present in the 1996
fact sheet, which indicate that the instream waste concentration should be changed to 5.1 %.
Fact S11--et
NTIDES NC00250 i 1 Renewal
pa"i_

Such a change only affects the toxicity test limit and rpa calculations. The BOD, limit is based
on secondary treatment and the ammonia limit is based on ammonia toxicity.
In addition, a 1995 modification to the permit granted some reprieve from 85% removal of TSS
and BOD. Due to the characteristics of the influent wastestream (largely textile waste that is
relatively low in suspended solids and BOD), the Division changed the percent removal to 75%.
Recent data suggest that it is appropriate to continue this for TSS, but not for BOD (where they
are consistently achieving better than 85% removal). The Permittee's justification for continuing
this variance is attached. The Division has judged all other previous parameters and limits to be
'appropriate for renewal.
Reasonable Potential Analysis (RPA) The Division conducted EPA -recommended analyses to
determine the reasonable potential for toxicants to be discharged by this facility, based on three
years of DMR data (1999-2001) and LTMP data dating from 1997 to present. Calculations
included parameters listed in the previous permit and pre-treatment documents to include:
cadmium, chromium, copper; nickel, lead, zinc, mercury, silver, arsenic, cyanide and selenium.
Data for molybdenum and phenols (both monitored through the LTMP plan) were reviewed, but
no reasonable potential analysis was performed since no water quality criteria exist for either.
Phenols are of concern for organoleptic effects in water supply waters; since the class does not
change for over 3 miles downstream and dilution is high in this area, phenols are not expected to
be present in detectable amounts at the water supply intake. Average effluent value for
molybdenum was 3.5µg/L.
Reasonable potential was demonstrated for copper and silver. Both of these are action
level parameters, so monitoring only (2/month) will be imposed, given Eden's perfect toxicity
record. No reasonable potential exists for cadmium, chromium, nickel, lead, zinc, mercury,
arsenic, cyanide and selenium.
SUMMARY OF PROPOSED CHANGES
In keeping with Division policies the following changes are recommended:
The zinc monitoring frequency should be changed from 2/month to quarterly due to a
finding of no reasonable potential (and an excellent toxicity record).
Silver monitoring (2/month) should be added due to a finding of reasonable potential.
Note in cover letter regarding sewer overflows
All other permit limits and monitoring requirements are in keeping with Division policies and
NC and federal regulations.

Facility Description — Potential Facility Changes
Mebane Bridge Wastewater Treatment Plant
Page 1 of 1
There are presently no projected plans to make any changes at the Mebane Bridge
Plant.
We current have an engineer firm doing a long-term solids handling study. The
outcome of this study could likely lead to addition solids handling equipment being
installed from the study's finding. Possible improvements may include the need for a
second aerobic digester and a belt press.
As part of our capital improvements plan the following pieces of equipment have been
targeted for replacement over the next five years. Replace one floating aerator per
year, both mechanical barscreens, the chlorine contact chamber gates, and the sodium
bisulfite tank.
