Permit NC0020834
A (2). CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 76%.
The permit holder shall perform at a minimum, Quarterly monitoring using test procedures outlined
in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998,
or subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised -February 1998) or subsequent versions. The tests will be performed during the months of
March, June, September, and December. Effluent sampling for this testing shall be performed at
the NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or
ChV below the permit limit, then multiple -concentration testing shall be performed at a
minimum, in each of the two following months as described in "North Carolina Phase II
Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent
versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of
the highest concentration having no detectable impairment of reproduction or survival and the
lowest concentration that does have a detectable impairment of reproduction or survival. The
definition of "detectable impairment," collection methods, exposure regimes, and further statistical
methods are specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (Revised -February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the
parameter 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.

A (3). NUTRIENT LIMITS SPECIAL CONDITION
Limits on total phosphorus and total nitrogen have not been included at this time because the
facility is participating in the nonpoint source trading option outlined in the Tar Pamlico NSW
Implementation Strategy Phase II, which was adopted December 8, 1994. If compliance with any
element of this strategy, or subsequent approved revisions to the strategy is not maintained, the
Division reserves the right to reopen this permit to include nutrient limits. If requirements other
than those listed in this NPDES permit are adopted as part of a future revision to the strategy, the
Division reserves the right to reopen this permit to include these requirements.
A (4). MERCURY MONITORING
Mercury results submitted on the three pollutant scans accompanying the renewal application were
analyzed using Method 245.1. Within the first year of this permit, permittee will collect three
effluent samples, which shall be analyzed for mercury using EPA Method 1631 and the results
submitted to the Division.

3. Does the facility have operational or compliance problems? Please comment: For a couple of years
they have had sludge in the idle oxidation ditch. This needs to be removed and disposed before they
can use the unit again for emergency flows or to take the other ditch down for maintenance. There are
plans for doing so in the next few months.
Summarize your BIMS review of monitoring data (Notice(s) of violation within the last permit cycle;
Current enforcement action(s)): Historically had a few NH3/BOD excursions, but are now operating
better under new ORC Perkinson, doing closer monitoring of control parameters.

Adequate Digester Capacity? Yes ❑ No ® Sludge Storage Capacity? Yes El No
Please comment on current operational practices: At times the limited capacity of the digesters causes
interference with the desired wasting schedule. i.e. having to let MLSS build while decanting-'
digesters -or --having _them hauled, then wasting steadily over a short time, rather than -short wasting
sessions on a regular basis. Hauling can be held up by wet weather, causing binds.

Subject: Wastewater Plant Compliance Inspection
Warrenton, NC
NPDES Permit No. NC0020834
Warren County
Dear Mr. Carver:
On May 3, 2004 Mr. Myrl Nisely of the Raleigh Regional Office conducted an annual compliance
inspection of the Regional WWTP facility with the assistance of Mr. Bill Perkinson. Please note the
attached checklist, including the Comments at the end of some sections. Summary comments are as
follows:
1. The treatment system, permitted at 2.0 MGD, consists of the following units: a bar screen
and grit chamber, three lift pumps to two oxidation ditches, two secondary clarifiers, two
aerated waste sludge digesters, four tertiary sand filters, a chlorination system and contact
chamber, a sulfur dioxide dechlorinator, cascade post aeration and an effluent flow meter.
2. The permit is expiring in six months, so an application for renewal is due at the State at
this time. Mr. Perkinson had it ready for submittal in the next few days.
3. A check of the effluent flow meter against the staff gage showed an error of 13%. This is
outside the 10% limit. Have the meter recalibrated as soon as possible.
4. The grit chamber motor was out for repair. Whenever a treatment unit is taken out of
service, the operator is to telephone the RRO office to report it within 24 hours.
5. The lime slurry system has been refurbished and is proving to be a real asset for adjusting
pH in both the oxidation ditch and the sludge digesters.
6. More digester capacity is needed at this plant. Wasting must be carefully orchestrated,
with frequent decanting of liquid to make more space. The pattern of wasting could be
better optimized if space were available. Land application will be done in a few weeks.

7. The Facility has the responsibility of providing an annual report to citizens on the
performance of the wastewater and drinking water plants. The Public Works office,
without Mr. Perkinson's awareness of the process, has done this task. Teresa Gustkey
has expressed a desire to work with him in preparing a combined report for next year.
This wastewater treatment plant is compliant. Please notify me by phone or e-mail when items
# 3 and #4 have been completed. If there are any questions or comments, please contact Myrl
Nisely at [phone] or [e-mail].

BACKGROUND
The Warrenton WWTP (Class III) has a permitted flow of 2.0 MGD. The current permit expires
October 31, 2004, and the Town of Warrenton submitted an application for renewal in April
2004. The Division has received results of all three required pollutant scans and one of the
required 2"d species tests. The remaining 2"d species tests were scheduled for June and the
results will be forwarded as soon as possible. This facility receives primarily domestic (with
some light industrial) wastewater. It has no Significant Industrial Users and does not implement
a pretreatment program. The facility has not requested any changes to the permit.
Warrenton WWTP discharges into Fishing Creek, classified C NSW at this point, in the Tar
Pamlico Basin. The receiving waters are not listed as impaired on the current 303 (d) list (but the
Tar Pamlico basin does have a nutrient management strategy).
Since the Town of Warrenton is part of the Tar Pamlico Nutrient Trading Association, their
permit includes nutrient monitoring without limits. Also special condition language relating to
potential nutrient limits has been added to the permit.

Correspondence/Compliance
The Raleigh Regional Office (RRO) conducted several site visits during this permit term to
evaluate compliance. A Staff Report was also prepared in conjunction with the permit renewal.
RRO finds the facility to be in compliance with the NPDES permit and recommends renewal.
The Warrenton WWTP has received two Notices of Violation (NOVs)/civil penalties since 2002.
One was for violation of its monthly average limit for NH3-N in May 2003. The other was for
exceeding its BOD limits, both weekly average and monthly average, in September 2002. The
facility has been in compliance with its toxicity limit during this entire permit term.
In stream Data
Warrenton performs instream monitoring for temperature, dissolved oxygen, and fecal coliform.
Dissolved Oxygen values in the summer months in 2002 and 2003 sometimes fell below 5 mg/1
in both upstream and downstream locations. However, no trend was evident. The Tar Pamlico
River Basin Association is in the process of establishing an instream monitoring plan.
Warrenton is listed as a participating member.
PERMITTING STRATEGY
The previous and current effluent limits were based on guidelines and water quality standards.
The Division has judged previous parameters and limits to be appropriate for renewal with some
exceptions. Weekly average ammonia limits based on a 3:1 ratio with the monthly average will
be implemented in this permit. This is a new statewide policy that resulted from EPA
requirements. The resulting summer weekly average limit will be 6.0 mg/L and the winter limit
will be 12.0 mg/L. In addition, an annual pollutant scan will be added such that the Permittee
can collect the necessary data required by EPA Form 2A throughout the permit term. This
condition is now standard on all major municipal permits in North Carolina.
The Division conducted EPA -recommended analyses to determine the reasonable potential for
toxicants to be discharged by this facility, based on DMR data from January 2001-March 2004.
Calculations included copper and zinc. Results suggest reasonable potential for the facility to
discharge copper and zinc at levels toxic to aquatic life. However, both of these parameters are
action level. Therefore, limits for them are only included if they are determined to be causative of
toxicity in the discharge. Since the facility has not failed any toxicity test since 2000, no limits
will be added.
SUMMARY OF PROPOSED CHANGES
In keeping with Division policies, the following will be incorporated into the permit:
• New weekly average ammonia limits (both summer and winter)
• Annual pollutant scan

That's just what I need. When the results from the two tests in May and the one in June come in, could
you fax them too?

Hey Dawn,
I have spoken with Bill Perkinson (ORC) concerning alternate species testing on several occasions.
The Town is trying their best to meet all requirements of the NPDES Permit application.
Our database shows one test result received for alternate species testing in April 2004.. On 4/16/04, I
spoke with the Town's biological lab and the lab indicated that the 3/04 alternate species test was
invalidated due to pathogen interference.KB told him to retest (alternate species) in 4/04, perform 2
alternate species in 5/04 an 1 alternate species in 6/04.Aeromonus is most likely the bacteria that
attacked the fish gills.Aeromonus is a ubiquitous organism that becomes more prevalent during
periods of environmental stress. I'm faxing you the 4/04 alternate species data this morning. I don't
anticipate the facility having any problems with fathead minnow. kevin.

Kevin,
I'm just starting on a renewal for Warrenton, NC0020834. With their
application, they state that their remaining alternate species test
results would be sent to you (not me). If you've received those, could
you send me a copy? We need the info too. They were (supposedly) done
May 3, May 16, and June 7.
If it's a problem at all, I can contact the applicant and ask them to
send me a copy. I just thought if they did send one in, I'd try to get
it from you first.
Thanks,

4.3 Status and Recommendations of Previously Impaired Waters
There were no Impaired streams identified in the 1999 basin plan in this subbasin.
4.4 Status and Recommendations of Newly Impaired Waters
There are no newly Impaired waters in subbasin 03-03-04. Refer to Part 4.5 below for
information on waters with noted water quality impacts.
4.5 Status and Recommendations for Waters with Noted Impacts
The surface waters discussed in this section are not Impaired. However, notable water quality
problems and concerns have been documented for these waters based on this assessment. While
these waters are not Impaired, attention and resources should be focused on these waters to
prevent additional degradation or facilitate water quality improvement.
Waters in the following section are identified by assessment unit number (AU#). This number is
used to track defined segments in the water quality assessment database, 303(d) Impaired waters
list, and the various tables in this basin plan. The assessment unit number is a subset of the
DWQ index number (classification identification number). A letter attached to the end of the
AU# indicates that the assessment is smaller than the DWQ index segment. No letter indicates
that the assessment unit and the DWQ index segment are the same.
4.5.1 Fishing Creek [AU# 28-79-(29) and (21)]
Current Status and 2004 Recommendations
Fishing Creek (24.3 miles) is currently Supporting in the aquatic life category from Enfield
water supply intake to Beech Swamp because of a Good -Fair bioclassification at site B-1 in
2002. Filamentous algae were covering all habitats and leaf packs were rare at site B-1. The
next downstream monitoring site has a Good bioclassification, indicating water quality recovery.
Drought may be partially responsible for the lower bioclassification upstream. Total phosphorus
and iron were elevated at site A-13 as well.
DWQ will continue to monitor water quality in Fishing Creek to determine if the cause of the
depressed biological community is from extreme meteorological events or land use activities.
Land -disturbing activities should implement BMPs to minimize or prevent future impacts to
water quality in the Fishing Creek watershed.
Because of the potential water quality problems noted above and because Fishing Creek has
endangered species present, it has been identified by EEP as one of 27 local watersheds in the
basin with the greatest need and opportunity for stream and wetland restoration efforts. This
watershed will be given higher priority than nontargeted watersheds for implementation of EEP
restoration projects.

This letter is in reference to our current NPDES permit (NC0020834), which will expire on October 31,
2004. To satisfy the requirement of the renewal package, this letter is to serve as official notice for the
Town of Warrenton's request for the renewal of said permit.
On March 8, 2004, William Perkinson representing the Town of Warrenton, spoke with Kevin Bowden
of NC DENR / DWQ by phone conceming scheduling the three Priority Pollutant Analyses and four
Alternate Species Toxicity tests in conjunction with our permit renewal application. Mr. Bowden
recommended the following schedule.
Week Beginning March 14, 2004 AS Toxicity PPA
Week Beginning April 11, 2004 AS Toxicity PPA
Week Beginning May 3, 2004 AS Toxicity PPA
Week Beginning May 16, 2004 * AS Toxicity
Week Beginning June 7, 2004 AS Toxicity
NPDES Toxicity
NPDES Toxicity
* Replaces AS Toxicity originally scheduled for March 14,
2004 which was run and resulted invalid.
These tests are firmly scheduled with our contract laboratory Tritest, Inc. Test results from the March
14, 2004 PPA and April 11, 2004 AS Toxicity are included with the attached renewal package. The
remaining PPA results will be forwarded promptly to your office upon completion of the tests.
Remaining Altemate Species toxicity test results will be forwarded promptly to Mr. Bowden's office
upon completion of the tests.
We also want to include in this cover letter the required narrative regarding our facility sludge
management plan. It is as follows:
The sludge generated at the plant is wasted to aerobic digesters, where it is aerated until it is
suitable for land application. The sludge is then hauled away and land applied by Granville
Farms of Oxford, NC (Permit No. WQ0000838).
Sludge Vector Attraction and Pathogens reduction are accomplished in accordance with EPA
503 Regulation, Option 3 (Additional Digestion of Sludge) and Option 12 (Raising the pH of
Domestic Septage).

Macon, here is what I have been able to find out:
1) Change of operations for the Warrenton WWTP
Attached is a name change form to use. Yet much of it doesn't apply to this situation
because ownership is not changing, but the relationship of the permit holder is.
Ownership of the plant is right now shown to be Miles, Wa A. on the computer, with the
permit in the name of Mitchell, C. W. Please use the form to explain what the change in
relationship is intended to be, and submit it to the address near the end of the form. There
is no fee involved, I was told.
2) Building an Animal Shelter with Sewer Connecting to the WWTP
This sewer would need to meet minimum design criteria, and would be permitted under a
Non -discharge permit. The best way to do this project would be to locate an engineer who
is already familiar with the State's fast track sewer permitting. He would apply using a
form found at http://h2o.enr.state.nc.us/ndpu/ExpressPermitting.html
He would submit a package to us containing an engineering checklist. We'll review the
application, making sure the WWTP has capacity for the new flow and other details, we
then issue the permit, the sewer would be built, then the engineer would submit As Built
drawing and his engineering certification that minimum criteria were met.
I hope this is fairly clear. If not, please call me again and we'll take another stab at it.

Hi ya!
I was out in the upper Tar basin on Friday and visited two outfalls while I was out and about.
For your records here are the coordinates for those two outfalls. I'm providing them in two formats. Let me
know if you need another. I can convert them.
Oxford WWTP discharges to Fishing Creek at:
36.27688 (36 16.613)
78.59107 (78 35.464)
Warrenton WWTP discharges to Fishing Creek at:
36.38035 (36 22.$2t) J(, L ,
, 78.16820 (78 10.092)

Judy, I'm not sure who in your office might be interested in these coordinates. Can
the appropriate person(s)? See you this afternoon.
Thanks!

On March 8, 2004, I spoke with Kevin Bowden of NC DENR / DWQ by phone concerning scheduling
the three Priority Pollutant Analyses and four Alternate Species Toxicity tests in conjunction with our
permit renewal application. Our renewal application (Perrnit NC0020834) is due to your office no later
than May 4, 2004. Mr. Bowden recommended the following schedule.
Week Beginning March 14, 2004 AS Toxicity PPA NPDES Toxicity
Week Beginning April 11, 2004 AS Toxicity PPA
Week Beginning May 3, 2004 AS Toxicity PPA
Week Beginning June 7, 2004 AS Toxicity NPDES Toxicity
These tests have now been firmly scheduled with our contract laboratory Tritest, Inc. Our renewal
application along with required data will be sent to your office before the May 4, 2004 deadline. PPA
results that come in after the May 4, 2004 deadline will be forwarded promptly to your office. Alternate
Species toxicity test results that come in after the deadline will be forwarded promptly to Mr. Bowden's
office.
We appreciate your direction and assistance in connection with this matter.
Sincerely,

Subject: Rc: NC0020834 !Warrenton! Mercury monitoring
From: Tom Bclnick <[e-mail]>
Date: The, 19 Aug 2003 09:34:39 -0400
To: Charles Weaver <charles.weaver(a ncmail.net>
FYI- The letters we sent them state that all effluent samples that they
collect will need to be run with the low level analysis. This includes future
effluent samples collected in support 2f_thi_r .r aemal_.appli ati.on (PPA
Analysis) and any future Annual PPA requirements that might be included in
their next permit. They do not currently have effluent mercury monitoring
requirements for their NPDES effluent Sheet or Pretreatment.
Charles Weaver wrote:
Tom - the current permit [issued 12/30/2000] for Warrenton doesn't
require any mercury monitoring. Yet they were on the list for 1631 -
they got the letter last year and this year.
Wayne Mitchell from the Town called asking about it - I told him you
would call him back and explain about the 1631 requirement. I'm puzzled
that they're on the list when their permit has no limit and no monitoring.
Mr. Mitchell will be out this morning but will return after 1 p.m. His
number is 252 257-1776.
Thanks,
