Subject: NPDES Permit
Warrenton WWTP
Permit No. NCO020834
Warren County
In accordance with the application for discharge permit, the Division is forwarding
herewith the subject NPDES permit. This permit is issued pursuant to the requirements of North
Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina
and the U.S. Environmental Protection Agency dated May 9, 1994.
The Division received your comments dated November 17, submitted on behalf of the
county, regarding the increased nutrient sampling requirement. The Division has modified the
weekly testing requirement for total nitrogen and total phosphorus. The increased monitoring
shall not commence until July 2001 to allow the county time to budget the weekly frequency. This
monitoring is necessary due to the continued concerns of nutrient loading to the Tar Pamlico River
Basin. Should the county find consistent minimal results for total nitrogen or total phosphorus,
the Division may modify the requirement at the next permit renewal. The county may also wish to
discuss the weekly monitoring requirement during the next negotiated agreement between the
Division and the Tar Pamlico Association in 2004.
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, Mail Service Center 6714, 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 except after notice to the Division of
Water Quality. The Division of Water Quality 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, the Division of Land Resources, the Coastal Area Management Act, or
any other federal or local governmental permit.

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, auarterlu 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 Il 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: 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.

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.

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
SECTION A. DEFINITIONS
1. Permit Issuing Authority
The Director of the Division of Water Quality.
2. DEM or "the Division"
Means the Division of Water Quality, Department of Environment, Health and Natural Resources.
3. EMC
Used herein means the North Carolina Environmental Management Commission.
4. Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33 USC
1251, et. seq.
5. Mass /Dav Measurements
The "monthly average discharge' is defined as the total mass of all daily discharges sampled
and/or measured during a calendar month on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
month. It is therefore, an arithmetic mean found by adding the weights of the pollutant found
each day of the month and then dividing this sum by the number of days the tests were
reported. The limitation is identified as "Monthly Average' in Part I of the permit.
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar week (Sunday - Saturday) on which daily discharges are
sampled and measured, divided by the number of daily discharges sampled and/or measured
during such week. It is, therefore, an arithmetic mean found by adding the weights of
pollutants found each day of the week and then dividing this sum by the number of days the
tests were reported. This limitation is identified as "Weekly Average" in Part I of the permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged dunng a
calendar day. If only one sample is taken during any calendar day the weight of pollutant
calculated from it is the "maximum daily discharge." This limitation is identified as "Daily
Maximum," in Part I of the permit.
d. The "average annual discharge' is defined as the total mass of all daily discharges sampled
and/or measured during the calendar year on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found each
day of the year and then dividing this sum by the number of days the tests were reported. This
limitation is defined as "Annual Average" in Part I of the permit.

Pan II
Page 2 of 14
6. Concentration Measurement
The "average monthly concentration,' other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar month on
which daily discharges are sampled and measured, divided by the number of daily discharges
sampled and/or measured during such month (arithmetic mean of the daily concentration
values). The daily concentration value is equal to the concentration of a composite sample or in
the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples
collected during that calendar day. The average monthly count for fecal coliform bacteria is
the geometric mean of the counts for samples collected during a calendar month. This
limitation is identified as "Monthly Average" under "Other Limits' in Part I of the permit.
b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar week
(Sunday/Saturday) on which daily discharges are sampled and measured divided by the
number of daily discharges sampled and/or measured during such week (arithmetic mean of the
daily concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average weekly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar week. This limitation is identified as "Weekly Average' under "Other Limits" in
Part I of the permit.
c. The "maximum daily concentration" is the concentration of a pollutant discharge during a
calendar day. If only one sample is taken during any calendar day the concentration of
pollutant calculated from it is the "Maximum Daily Concentration'. It is identified as "Daily
Maximum" under "Other Limits' in Part 1 of the permit.
The "average annual concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar year on
which daily discharges are sampled and measured divided by the number of daily discharges
sampled and/or measured during such year (arithmetic mean of the daily concentration
values). The daily concentration value is equal to the concentration of a composite sample or in
the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples
collected during that calendar day . The average yearly count for fecal coliform bacteria is the
geometric mean of the counts for samples collected during a calendar year. This limitation is
identified as "Annual Average' under "Other Limits" in Part I of the permit.
e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount of
dissolved oxygen required to be available in the effluent prior to discharge averaged over a
calendar day. If only one dissolved oxygen sample is taken over a calendar day, the sample is
considered to be the "daily average concentration" for the discharge. It is identified as "daily
average" in the text of Part 1.
The "quarterly average concentration" is the average of all samples taken over a calendar
quarter. It is identified as "Quarterly Average Limitation' in the text of Part I of the permit.
g. A calendar quarter is defined as one of the following distinct periods: January through March,
April through June, July through September, and October through December.

7. Other Measurements
a. Flow, (MGD): The flow limit expressed in this permit is the 24 hours average flow, averaged
monthly. It is determined as the arithmetic mean of the total daily flows recorded during the
calendar month.
b. An "instantaneous flow measurement" is a measure of flow taken at the time of sampling, when
both the sample and flow will be representative of the total discharge.
c. A "continuous flow measurement" is a measure of discharge flow from the facility which occurs
continually without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for
infrequent maintenance activities on the flow device.
8. Types of Samples
a. Composite Sample: A composite sample shall consist of:
(1) a series of grab samples collected at equal time intervals over a 24 hour period of discharge
and combined proportional to the rate of flow measured at the time of individual sample
collection, or
(2) a series of grab samples of equal volume collected over a 24 hour period with the time
intervals between samples determined by a preset number of gallons passing the sampling
point. Flow measurement between sample intervals shall be determined by use of a flow
recorder and totalizer, and the present gallon interval between sample collection fixed at
no greater than 1/24 of the expected total daily flow at the treatment system, or
(3) a single, continuous sample collected over a 24 hour period proportional to the rate of flow.
In accordance with (1) above, the time interval between influent grab samples shall be no
greater than once per hour, and the time interval between effluent grab samples shall be no
greater than once per hour except at wastewater treatment systems having a detention time of
greater than 24 hours. In such cases, effluent grab samples may be collected at time intervals
evenly spaced over the 24 hour period which are equal in number of hours to the detention time
of the system in number of days. However, in no case may the time interval between effluent
grab samples be greater than six (6) hours nor the number of samples less than four (4) during a
24 hour sampling period.
b. Grab Sample: Grab samples are individual
exceeding 15 minutes; the grab sample can
representative of the discharge or the receiving
9. Calculation of Means
samples collected over a period of time not
be taken manually. Grab samples must be
wa ters.
a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the individual
values divided by the number of individual values.
b. Geometric Mean: The geometric mean of any set of values is the Nth root of the product of the
individual values where N is equal to the number of individual values. The geometric mean is
equivalent to the antilog of the arithmetic mean of the logarithms of the individual values.
For purposes of calculating the geometric mean, values of zero (0) shall be considered to be one
(1).
c. Weighted by Flow Value: Weighted by flow value means the summation of each concentration
times its respective flow divided by the summation of the respective flows.

Part H

10. Calendar Day
A calendar day is defined as the period from midnight of one day until midnight of the next day.
However, for purposes of this permit, any consecutive 24-hour period that reasonably represents
the calendar day may be used for sampling.
11. Hazardous Substance
A hazardous substance means any substance designated under 40 CFR Part 116 pursuant to Section
311 of the Clean Water Act.

SECTION C. OPERATION AND MAINTENANCE OF POLLUTION CONTROLS
1. Certified 012grator
Pursuant to Chapter 9OA44 of North Carolina General Statutes, and upon classification of the
facility by the Certification Commission, the permittee shall employ a certified wastewater
treatment plant operator in responsible charge (ORC) of the wastewater treatment facilities. Such
operator must hold a certification of the grade equivalent to or greater than the classification
assigned to the wastewater treatment facilities by the Certification Commission. The permittee
must also employ a certified back-up operator of the appropriate type and any grade to comply
with the conditions of Title 15A, Chapter 8A .0202. The ORC of the facility must visit each Class I
facility at least weekly and each Class II, III, and IV facility at least daily, excluding weekends
and holidays, and must properly manage and document daily operation and maintenance of the
facility and must comply with all other conditions of Title 15A, Chapter 8A .0202. Once the
facility is classified, the permittee shall submit a letter to the Certification Commission which
designates the operator in responsible charge within thirty days after the wastewater treatment
facilities are 50% complete.
2. Proper Operation and Maintenance
The permittee shall at all times properly operate and maintain all facilities and systems of
treatment and control (and related appurtenances) which are installed or used by the permittee to
achieve compliance with the conditions of this permit. Proper operation and maintenance also
includes adequate laboratory controls and appropriate quality assurance procedures. This provision
requires the operation of back-up or auxiliary facilities or similar systems which are installed by a
permittee only when the operation is necessary to achieve compliance with the conditions of the
permit.

Part II
Page 8 of 14
3. Need to Halt or Reduce not a Defense
It shall not be a defense for a permittee in an enforcement action that it would have been necessary
to halt or reduce the permitted activity in order to maintain compliance with the condition of this
permit.
4. Massing of Treatment Facilities
a. Definitions
(1) "Bypass" means the known diversion of waste streams from any portion of a treatment
facility including the collection system, which is not a designed or established or operating
mode for the facility.
(2) 'Severe property damage" means substantial physical damage to property, damage to the
treatment facilities which causes them to become inoperable, or substantial and permanent
loss of natural resources which can reasonably be expected to occur in the absence of a
bypass. Severe property damage does not mean economic loss caused by delays in
production.
b. Bypass not exceeding limitations.
The permittee may allow any bypass to occur which -does not cause effluent limitations to be
exceeded, but only if it also is for essential maintenance to assure efficient operation. These
bypasses are not subject to the provisions of Paragraphs c. and d. of this section.
c. Notice
(1) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it shall
submit prior notice, if possible at least ten days before the date of the bypass; including an
evaluation of the anticipated quality and affect of the bypass.
(2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as
required in Part II, E. 6. of this permit. (24 hour notice).
d. Prohibition of Bypass
(1) Bypass is prohibited and the Permit Issuing Authority may take enforcement action against
a permittee for bypass, unless:
(A) damage;
was unavoidable to prevent loss of life, personal injury or severe property
(B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment
facilities, retention of untreated wastes or maintenance during normal periods of
equipment downtime. This condition is not satisfied if adequate backup equipment should
have been installed in the exercise of reasonable engineering judgment to prevent a bypass
which occurred during normal periods of equipment downtime or preventive maintenance;
and
(C) The permittee submitted notices as required under Paragraph c. of this section.
(2) The Permit Issuing Authority may approve an anticipated bypass, after considering its
adverse affects, if the Permit Issuing Authority determines that it will meet the three
conditions listed above in Paragraph d. (1) of this section.

PART III
OTHER REQUIREMENTS
A. Requirements for Control of Pollutants Attributable to Industrial Users
1. Effluent limitations are listed in Part I of this permit. Other pollutants attributable to inputs from industries
using the municipal system may be present in the pemuttee s discharge. At such time as sufficient information
becomes available to establish limitations for such pollutants, this permit may be revised to specify effluent
limitations for any or all of such other pollutants in accordance with best practicable technology or water
quality standards.
2. Under no circumstances shall the permittee allow introduction of the following wastes in the waste treatment
system:
a. Pollutants which create a fire or explosion hazard in the POTW, including, but not limited to,
wastestreams with a closed cup flashpoint of less than 140 Degrees Fahrenheit or 60 degrees centigrade
using the test methods specified in ATSM standards D-93-79, D-93-80, or D-3278 (incorporated by
reference, see 40 CFR 260.11). This prohibition does not apply to any aqueous solution containing less
than 24 percent alcohol by volume which would otherwise be a hazardous waste under 40 CFR 261.21 by
virtue of having a closed cup flashpoint of less than 140 degrees Fahrenheit or 60 degrees centigrade;
b. Wastes which will cause corrosive structural damage to treatment works, and in no case discharges with
pH less than 5.0 standard units unless the system is specifically designed to accommodate such discharges;
c. Solid or viscous substances in amounts which cause obstructions to the flow in sewers or interference with
the proper operation of the treatment works;
d. Wastewaters at a flow rate and/or pollutant concentration which will cause an inhibition or disruption of
the POTW, its treatment processes, operation, or sludge use and disposal;
e. Heat in amounts which will inhibit biological activity in the treatment works, resulting in interference but
in no case heat in such quantities that the temperature at the treatment works influent exceeds 40°C
(104T) unless the works are designed to accommodate such heat;
f. Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in amounts that will cause
interference or pass through;
g. Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in quantity that
may cause acute worker health and safety problems;
h. Any trucked or hauled pollutants, except at discharge points designated by the POTW.
3. With regard to the effluent requirements listed in Part I of this permit, it may be necessary for the permittee to
supplement the requirements of the Federal Pretreatment Standards (40 CFR, Part 403) to ensure compliance
by the permittee with all applicable effluent limitations. Such actions by the permittee may be necessary
regarding some or all of the industries discharging to the municipal system.
4. The permittee shall require any industrial discharges into the permitted system to meet Federal Pretreatment
Standards promulgated in response to Section 307(b) of the Act. Prior to accepting wastewater from any
significant industrial user, the permittee shall either develop and submit to the Division a Pretreatment Program
for approval per 15 NCAC 2H .0907(a) or modify an existing Pretreatment Program per 15 NCAC 2H .0907(b).
5. This permit shall be modified, or alternatively, revoked and reissued, to incorporate or modify an approved
POTW Pretreatment Program or to include a compliance schedule for the development of a POTW
Pretreatment Program as required under Section 402(b)(8) of the Clean Water Act and implementing
regulations or by the requirements of the approved State pretreatment program, as appropriate.

SUBJECT: Advance Notice of Renewal Application Requirements
Permit NC0020834
Warrenton WWTP
Dear Permittee:
Your NPDES permit for a municipally owned/operated WWTP expires on October 31, 2009. This notice is
being sent to explain the requirements for your permit renewal application.
You are receiving this advance notice because your facility has a permitted flow at or above 1
MGD, or the facility receives industrial [pretreatment] wastewater. If either of these criteria no
longer applies, contact the NPDES Unit before submitting a renewal application.
Federal (40 CFR 122) and state (15A NCAC 2H.0105(e)) regulations require that permit renewal
applications be filed at least 180 days prior to expiration of the current permit. Your renewal application is
due to the Division postmarked no later than May 4.2009. Failure to apply for renewal by the appropriate
deadline may result in a civil penalty assessment or other enforcement activity at the discretion of the
Director.
The U.S. EPA revised and expanded the application requirements for municipal permits, effective August 1,
2001. EPA form 2A is attached to this Notice, and must be used for your permit renewal application. The
new application requirements mandate additional effluent testing:
1. Conduct three Priority Pollutant Analyses (PPAs) and submit results with your renewal
application. Collect samples for the PPAs in conjunction with sampling for your current
quarterly toxicity test. The new PPA requirements differ from previous versions. Each PPA
must include:
➢ Analyses for all total recoverable metals listed in Part D of form 2A. This includes metals
that are not normally monitored through your NPDES permit.
➢ Analyses for total phenolic compounds and hardness.
➢ Analyses for all of the volatile organic compounds listed in Part D.
➢ Analyses for all of the acid -extractable compounds listed in Part D.
➢ Analyses for all base -neutral compounds listed in Part D.
➢ Analyses for Total Mercury must be performed using EPA Method 1631.
2. Conduct four toxicity tests for an organism other than Ceriodaphnia and submit results with
your renewal application. The tests should be conducted quarterly, with samples collected on the
same day as your current toxicity test. Call the Aquatic Toxicology Unit at [phone] for
guidance in conducting the additional tests.

The pollutant and toxicity analyses described above must accompany your permit renewal
application, or any major permit modification request. The Division cannot draft your permit without the
additional data. Any data submitted cannot be over 4 % years old, and must account for seasonal
variation (samples cannot be collected during the same season each year if collected over multiple years).
PLEASE NOTE: If your existing permit contains a requirement for annual PPAs, additional PPAs
are not required [provided you have conducted at least 3 scans prior to submitting your application).
If any wastewater discharge will occur after the current permit expires, this NPDES permit must be
renewed. Discharge of wastewater without a valid permit would violate Federal and North Carolina law.
Unpermitted discharges of wastewater could result in assessment of civil penalties of up to $25,000 per day.
Use the checklist below to complete your renewal package. The checklist identifies the items you
must submit with the permit renewal application. If all wastewater discharge has ceased at this facility and
you wish to rescind this permit, please contact me. My telephone number, fax number and e-mail address
are listed at the bottom of the previous page.
Sincerely,
Charles H. Weaver, Jr.

NPDES File
The following items are REQUIRED for all renewal packages:
o A cover letter requesting renewal of the permit and documenting any changes at the facility since
issuance of the last permit. Submit one signed original and two copies.
o The completed EPA Form 2A application (copy attached), signed by the permittee or an Authorized
Representative. Submit one signed original and two copies.
o If an Authorized Representative (such as a consulting engineer or environmental consultant) prepares

RE: Implementation of the Tar Pamlico Basin Association's Monitoring Coalition
NPDES Permit Modification for Instream Monitoring
NCO020834 Warrenton WWTP
Warren County
Dear Mr. Carver:
As a member of the Tar Pamlico Basin Association's monitoring coalition, your facility and the NC Division of
Water Quality (DWQ) have entered into an agreement that provides both parties with an effective monitoring tool
within the Tar Pamlico River basin. By this letter the DWQ is waiving the instream monitoring requirements as
specified within your individual NPDES permit beginning March 1, 2007 when the association begins monitoring
of the basin as specified within the Memorandum of Agreement (MOA). This agreement identifies the stations,
parameters, and frequency of monitoring required of the association in order that instream monitoring
requirements be waived for members. Should your membership in the association be terminated, you must notify
DWQ immediately and the instream monitoring requirements in your permit will be reinstated.
All other terms and conditions in the original permit remain unchanged and in full effect. These modifications are

Dear Mr. Wakild:
WOOD 0bq
This letter serves as an official response to your letter dated June 28, 2006 instructing the Town of
Warrenton to provide a plan for providing uninterrupted chlorination and dechlorination when the
Wastewater Treatment is running on generator power.
We have made good progress in addressing this issue. After consulting with our contractor that
provides and services our chlorination equipment, we purchased a portable 1 horsepower 120-volt
booster pump with 20 feet of 2-inch suction hose and 100 feet of 2-inch discharge hose.
It is a distance of approximately 100 feet from our chlorine contact basin to our chemical feed room
where chlorine gas and sulfur dioxide gas are injected into carrying water. We added a quick couple
connection to our carrying water line in the chemical feed room. We have an existing 120-volt outlet
that is live when we are running on generator power. This outlet is located in the immediate area of
where the booster pump needs to be set up in the event we are running on emergency power.
The booster pump and hoses have quick couple connectors. The equipment is light weight and can be
set up and running in approximately 10 minutes by one person. It is capable of supplying an ample
amount of water for injecting our chlorine and sulfur dioxide gas.
In the event the plant experiences a power failure and goes on generator power, our dialer is
programmed to call an operator. It is our procedure to come to the plant, check all systems, and
remain on site until the plant is back on utility power. The booster pump and apparatus will allow us to
continue chlorination and dechlorination during such events.
On July 31, 2006 we took Clarifier no. 1 out of service and brought in a contractor to make the
necessary concrete repairs. The repair work should be completed in 3 to 4 days. An additional 12
days is needed for the concrete to cure properly. We will then put the unit back on line on or around
August 16, 2006.
We greatly appreciate your direction and assistance in helping our plant perform property and meet our
permit requirements.
Sincerely,
William R. Parkinson

Subject: Compliance Evaluation Inspection
Warren County Wastewater Treatment Plant
NPDES Permit No. NCO020834
Warren County
Dear Mr. Carver:
On June 16, 2006 Mr. Myrl Nisely of the Raleigh Regional Office conducted a compliance
inspection of the Warren County Wastewater Treatment Plant with the assistance of Mr. William
Perkinson, ORC of the facility. His help was appreciated as it facilitated the inspection process.
The plant was compliant. Please see the attached inspection checklist for specific comments.
We emphasize the following points:
The standby generator is not large enough to run all parts of the plant during a power
failure. The pumps supplying water for chlorine injection are among the components
idled. Therefore, disinfection stops. This termination of chlorine injection immediately
begins a violation of the permit. Attempts at manually feeding some other form of
chlorine are troublesome, unreliable and unsafe for those handling the material. Please
investigate some means of supplying emergency power or otherwise assuring
uninterrupted disinfection and dechlorination. Please respond in writing with a plan by
August 4, 2006.
2. Clarifier #1 effluent piping includes a concrete box on the outside of the clarifier that is
leaking and showing significant deterioration of the concrete. This needs to be repaired
soon to avoid a catastrophic failure that would release effluent inside the plant.
If you have any questions regarding this inspection, please contact Myrl Nisely at (919) 791-
4200.

In this letter we wish to provide written notification to the Regional Office of NCDWQ that the Town of
Warrenton WWTP has a vacancy for Back-up ORC. This letter supports the phone conversation that
you and I had on Friday, January 27, 2006 concerning this matter.
The Town of Warrenton suspended Darnell Bullock, who is currently listed as WWTP Back-up ORC,
on January 17, 2006. He has temporarily been relieved of all duties and responsibilities associated with
his job with the Town. A final decision concerning his employment will be made on February 13, 2006.
Thus Mr. Bullock is no longer able to serve or be designated as the WWTP Back-up ORC. A
replacement for the Town's WWTP Back-up ORC designation will be made within 120 days from the
date of January 17, 2006,
Thank you for your assistance and direction regarding this matter.

Subject: Compliance Evaluation Inspection
Warren County Wastewater Treatment Plant
NPDES Permit No. NCO020834
Warren County
Dear Mr. Carver:
On February 24, 2004 Mr. Myrl Nisely and Mr. Christopher Wu of the Raleigh Regional Office
conducted a compliance inspection of the Warren County Wastewater Treatment Plant with the
assistance of Mr. William Perkinson, ORC of the facility. His help was appreciated as it
facilitated the inspection process. The plant was compliant.
The following observations were made:
1. The permit was issued with the understanding that 3 low level Hg analyses and 1 Priority
Pollutant Analysis (PPA) scan would be submitted within 1 year. Mr. Perkinson is on
schedule to accomplish this. Because the PPA includes a mercury, that test will
constitute one of the three required.
2. The oxidation ditch liquor was black from industrial dyes. This is normal for this plant
and it does not interfere with biological treatment.
3. The sludge blanket level in the secondary clarifier is higher than the allotted guideline of
1/3 the depth of the tank. Increased sludge digester capacity is necessary to allow the
wasting necessary for proper operation of the activated sludge system. Mr. Perkinson
stated that Macon Robinson is undertaking a plan for upgrading the WWTP. We urge
any upgrade to include digester capacity.
4. The sludge inventory throughout the plant is high. Mr. Perkinson mentioned that he was
expecting to apply the sludge to the land soon. Six loads were actually removed from
one digester on 2/23/2005. At present, virtually no wasting is possible without losing the
vector reduction process already accomplished in the digester tanks.
5. Backwashing is completed manually about once a week or as water level dictates.

6. The generator wa... --_ t tested during the inspection. Mr. P ison said that the annual
inspection by Gregory Poole had just been conducted on February 23, 2005.
A separate issue that must be addressed is the lack of a stormwater program that is required
under general permit NCG11000. Phase I of the municipal stormwater regulations require that
all municipal wastewater plants discharging greater than 1 MGD of flow and having a point
source discharge of stormwater must establish a stormwater program. The implementation of
this Phase I requirement was delayed and did not become effective until March 2003 along with
Phase H. At that time, the Town should have submitted a Notice of Intent (NOI) application
form to obtain that permit. During last year's inspection (February 23, 2004), Mr. Nisely and
Mr. Perkinson discussed the question of whether to apply. A list of designated towns and
counties in the Phase II rules did not show Warrenton or Warren County to be included in Phase
II, so the permit was not pursued. In reality, every municipal W WTP over 1 MGD that has at
least one point discharge of stormwater must obtain this permit. Now that a clear understanding
shows the need for NCGI 1000, please submit the NOI by March 11, 2005.
If you have any questions regarding the attached report or any of our findings, please contact
Myrl Nisely at: [phone].

We have scheduled an on -site inspection of your laboratory for approximately 8:00 a.m., December 7, 2004. The scope of the
inspection will include all methods marked on Attachment I of the laboratory's current North Carolina Wastewater /Groundwater Certificate
and /or marked on the application for NC Wastewater/Groundwater Laboratory Certification. A copy of the current Attachment I is enclosed
for your reference. The purpose of the inspection will be to verify the laboratory's documented quality control/quality assurance procedures
and adequacy in meeting the requirements of 15A NCAC 2H .0800.
Enclosed are inspection checklists for the upcoming inspection. Prior to the on -site inspection, excluding the data review sections,
please have your analysts complete each checklist. Any checklists that your laboratory is unable to complete, or any specific items that you
do not understand, will be completed during the inspection. Completion of these checklists prior to the on -site inspection, with comments
by analysts relating to specific procedural differences will help avoid any unnecessary interruption of the analyst's schedule.
Please have available the DMR report sheets and corresponding bench data available for the months of January, April and
August 2004 for us to review. If further data or report sheets are required, we Will notify you during the inspection. These data sets will be
used to assess the quality of your data during the inspection.
Review your last inspection report (Inspection date: November 21, 2003), to assure that all deficiencies have been corrected. If the
deficiencies cited in the December 31, 2003 inspection report have not been corrected, enforcement action will be recommended.
Thank you for your time and cooperation. I can be contacted at [phone] (extension 272), if you have questions.

Dear Mr. Carver:
Endosed with this letter is a copy of the draft permit for your facility. Please review the draft carefully to ensure
thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from your current permit:
➢ Based on adverse comments from EPA, the Division of Water Quality was required to implement weekly average
NH3-N (ammonia) limits for municipal facilities, as required by the Code of Federal Regulation. This implementation
policy was adopted October 15, 2002. The weekly average is three times the monthly average value (with a cap of 35
mg/l.) This permit includes both monthly and weekly average limits for NH3-N.
➢ A Priority Pollutant Analysis special condition has been added as required by EPA for all facilities with a flow
limit above 1.0 MGD.
Please note that Warrenton WWTP is required to analyze all samples for mercury using EPA Method 1631. The three
pollutant scans submitted with the renewal application report using Method 245.1. Special Condition A.(4.) requires
correction of this oversight.
Submit any comments to me no later than thirty days following your receipt of the draft. Comments should be sent
to the address listed at the bottom of this page. If no adverse comments are received from the public or from you,
this permit will likely be issued in September with an effective date of November 1, 2004.

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.

Permit NCO020834
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.

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.
Data Review
DMR data from May 2002 through May 2004 were reviewed. Monthly average data are
summarized below.
Max 1 1.0 26.1 1 11.2 9.4 7.9 83.5 3.9 25.9 1.9 LTD
Min 0.5 9.3 7.2 0.2 0.5 9.5 0.7 2.3 0.3 1.8
NCO020834 Conventional Data (May 2002-May 2004)

Correspondence/Complia......
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.
Instream 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

Subject: Wastewater Plant Compliance Inspection
Warrenton, NC
NPDES Permit No. NCO020834
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 W WTP 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].

Mr. Charles H. Weaver, Jr.
NC DENR / DWQ

Raleigh, NC 27699-1617
Dear Mr. Weaver
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 concerning scheduling the three Priority Pollutant Analyses and four
Altemate Species Toxicity tests in conjunction with our permit renewal application. 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 May 16, 2004 ' AS Toxicity
Week Beginning June 7, 2004 AS 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).

We appreciate your direction and assistance in connection with our permit renewal. If you have any
questions regarding our application, please contact William Perkinson at 252-257-1776.

This letter is a response to your letter dated January 9, 2004 instructing the Town of Warrenton to
evaluate putting the lime sib/slurry tank system back into use.
We have made good progress in cieaning and performing maintenance on the slurry tank, slurry pump,
and relating piping. It appears that this equipment now is in adequate working order.
We have also determined that we are unable to use the pellet lime that is stored in the sib. This lime
was purchased in error approximately two years ago. It does not dissolve properly and quickly clogs up
the equipment. We also do not have adequate safety controls and equipment to run this type of time
due to the heat that is generated when it is mixed with water.
There is no straightforward or simple way to remove the several tons of pellet time that is currently
stored in our lime silo. We have begun the process of consulting individuals and companies that
specialize in handling this material. Our goal is to devise a way to remove the pellet lime and replace it
with powdered hydrated lime as soon as possible.
We hereby petition the State to provide the Town of Warrenton with some additional time to resolve this
problem
We greatty appreciate your direction and assistance in helping our plant perform property and meet our
permit requirements.

William R Perkinson

Subject: Considerations on Addition of Lime to the Oxidation Ditch
NPDES Permit No. NCO020834
Warren County
Dear Mr. Gardner:
Recent conversations with Mr. Bill Perkinson, ORC of the WWTP, have brought to light that the
lime silo/slung tank/piping arrangement for adding lime to the oxidation ditch for pH adjustment
has not been in use for many months. Bill was proposing to store bags of lime near the ditch for
easy handling as they are opened and dumped about midway down the length of the oxidation ditch.
Dumping of bags has been the technique used since the slurry equipment became dysfunctional.
The Division of Water Quality has concerns about dumping in this manner, and would like to see
the silo and other equipment be refurbished and put back into use.
1) The permit in Section B requires the permittee at all times to "provide the operation and
maintenance necessary to operate the existing facility at optimum efficiency".
2) Dumping lime powder into the ditch does not provide satisfactory agitation to assure rapid
dissolving of the lime. Lime may possibly be dumped so fast that it forms a lump in the
oxidation ditch that distributes very slowly, giving a slow elevation of pH. When the pH fails to
increase as quickly as needed, more bags would then be dumped, possibly resulting in a pH too
high, eventually.
3) There may be health concerns and even OSHA worker safety concerns in trying to add bags at
the side of the ditch. Spilling powder on skin or breathing the dust should be avoided.
We hereby request that the City evaluate putting the old system back into use. The problems with
the slurry tank and clogged piping to the ditch may have been caused when pelletized time was used
instead of the usual lime powder. Please reply to this request by February 13, 2004.
It should be noted for the future that anytime a piece of equipment is taken out of service, a
telephone call to the Raleigh Regional Office is required to report the change.
If there are any questions or comments, please contact me at [phone].

This laboratory was inspected to verify its compliance with the requirements of 15A NCAC 2H .0800 for the
analysis of environmental samples.
II. GENERAL COMMENTS:
This report reflects findings related to on -site inspection, application information and DMR review.
III. DEFICIENCIES, RECOMMENDATIONS, REQUIREMENTS, AND COMMENTS:
General:
A. COMMENT: Some of the benchsheets used by the laboratory do not contain all of the necessary labeling
information.
REQUIREMENT: All laboratories must use printed laboratory bench worksheets that include a space to enter
the signature or initials of the analyst, date of analyses, sample identification, volume of sample analyzed, value
from the measurement system, factor, final value to be reported, and each item must be recorded each time
samples are analyzed. Ref: 15A NCAC 2H .0805 (a) (7) (H).
B. COMMENT: The laboratory does not perform sufficient quality control for all duplicate sample analyses.
REQUIREMENT: Any time quality control results indicate an analytical problem, the problem must be resolved,
and any samples involved must be rerun if the holding time has not expired. Ref: 15A NCAC 2H .0805 (a) (7)
(F).
REQUIREMENT: Control limits for duplicate sample analyses must be established. No firm acceptance
values have been established, documented, or evaluated against results obtained on analyses. The results
obtained must be documented on the bench sheet and evaluated against the acceptance criteria to
demonstrate that the analyst was aware of any out -of -control situation and the corrective action that was
taken. Any samples not meeting the criteria must be reanalyzed if possible. If this is not possible, the data
must be flagged on the laboratory reports and Discharge Monitoring Reports (DMR) as all quality control
requirements not met.

•
Page 2
L
REQUIREMENT: Each laboratory shall develop and maintain a document outlining the analytical quality
control practices used for the parameters included in their certification. Supporting records shall be
maintained as evidence that these practices are being effectively carried out. Ref: 15A NCAC 2H .0805
(a)(7)•
COMMENT: The laboratory must calculate either the relative percent difference, or the absolute difference for
each duplicate pair analyzed. This value is then used to establish control charts or other appropriate acceptance
criteria. If duplicates fail to repeat within reasonable acceptance limits corrective actions must be taken. The
acceptance criteria should be listed on the bench sheets so that the analyst will be able to immediately confirm
whether or not the data falls within acceptable limits.
C. COMMENT: The laboratory does not maintain standard or reagent preparation logs.
REQUIREMENT: All analytical data pertinent to each certified analysis must be filed in an orderly manner as
to be readily available for inspection upon request. Ref: 15A NCAC 2H .0805 (a) (7) (A).
COMMENT: The laboratory needs to increase the documentation of reagents used, made, and standard
preparation. The preparation of all reagents, standards and media should be documented in a preparation log
or logs. Traceable identifiers should link solution preparation information to analytical batches in which the
solutions are used. Documentation of solution preparation should include the analyst's initials, date of
preparation, the volume or weight of standard used, the solvent and final volume of the solution. This
information as well as the vendor, manufacturer, lot number, and expiration date should be retained for
primary standards or chemicals and reagents used.
Total Residual Chlorine:
1. DEFICIENCY: The laboratory does not analyze a mid -range check standard each analysis day.
REQUIREMENT: Verify the standard curve daily by analyzing one or more standards within the linear range,
as specified in the individual method. The curve must be updated as set forth in the standard procedures,
each time the slope changes by more than 10 percent at midrange. Ref: 15A NCAC 2H .0805 (a) (7) (1).
D. COMMENT: The laboratory does not analyze a second source standard.
REQUIREMENT: Excluding Oil and Grease, all residue parameters, leachate extractions, residual chlorine
by titration, and coliform, analyze one known standard in addition to calibration standards each day samples
are analyzed to document accuracy. Analyze one suspended residue, one dissolved residue, one residual
chlorine and one oil and grease standard quarterly. Ref: 15A NCAC 2H .0805 (a) (7) (8).
REQUIREMENT: Analyze one known standard in addition to calibration standards each day samples are
analyzed to document accuracy. This LCS (laboratory control standard) must be from a second source. For
held curves for colorimetric methods, it must be analyzed after the initial CCV (continuing calibration
verification standard) is analyzed. It is recommended that this laboratory control standard, like the CCV, have
a mid -range concentration and not vary by more than ± 10%. If it does, the analysis is out of control. The
analysis must be terminated and the problem corrected. Ref: 15A NCAC 2H .0805 (a) (7) (B), (F), and
Standard Methods, 18th Edition - Method 1020 B.3.
COMMENT: The laboratory can perform an annual five -point standard verification curve. Thereafter, the
laboratory must verify the calibration curve each analysis day. To do this, the laboratory must analyze a
blank to zero the instrument and a mid -range check standard each day that samples are analyzed. The check
standard must be within ± 10% of its known value.

•
Page 3
Fecal Coliform:
E. COMMENT: No comparison test is conducted before a new lot of consumables are put into use.
REQUIREMENT: When a new lot of culture medium, pads, or membrane filters is to be used, a comparison of
the current lot in use, (reference lot) against the new lot (test lot), be made. Ref: Standard Methods, 181h Edition
- Method 9020 B.3d (page 9-7)
F. COMMENT: The laboratory calculates values from all dilutions that meet the 20-60 colonies per plate method
criteria in reporting the final value to be reported even when a 100ml-sample volume is analyzed.
REQUIREMENT: If a 100 ml sample is analyzed and the counts are less than 60 colonies: report the total
number of colonies present on the 100 ml sample. If zero counts are obtained report as <1/100 ml/ (This is a
whole volume sample). Ref: MEMO: Fecal Coliform Reporting, March 25, 2003.
IV. PAPER TRAIL INVESTIGATION:
This consisted of comparing data reported on DMR's submitted to this Division with the values obtained on
laboratory bench worksheets. Data was reviewed for the months of January, April, and August 2003. No data
transcription or reporting issues were observed at this time.
V. CONCLUSIONS:
Correcting the above deficiencies and comments and implementing the recommendations should help them to
produce quality data and meet certification requirements.
Please respond to all numbered Deficiencies and lettered Comments cited in this report.

SUBJECT: Renewal Application Requirements for Permit NC0020834
Warrenton WWI?
Dear Permittee:
Your NPDES permit for a municipally owned/operated W WTP expires on October 31.2004. This advance notice is
being sent to explain the new requirements for your permit renewal application.
You are receiving this advance notice because your facility has a permitted flow at or above 1 MGD, or.your
W WTP has a pretreatment program. If either of these criteria no longer apply to your facility, contact the NPDES
Unit before submitting a renewal application.
Federal (40 CFR 122) and state (15A NCAC 2H.0105(e)) regulations require that permit renewal applications be filed
at least 180 days prior to expiration of the current permit. Your renewal application is due to the Division no later
than May 4, 2004. Failure to apply for renewal by the appropriate deadline may result in a civil penalty assessment or
other enforcement activity at the discretion of the Director.
The U.S. EPA revised and expanded the application requirements for municipal permits, effective August 1, 2001.
EPA forms 1 and 2A are attached to this Notice, and must be used for your permit renewal application. The new
application requirements mandate additional effluent testing.
1. Conduct three Priority Pollutant Analyses (PPAs) and submit results with your renewal application.
Collect samples for the PPAs in conjunction with sampling for your current quarterly toxicity test. The
new PPA requirements differ from previous versions. Each PPA must include:
➢ Analyses for 1H total recoverable metals listed in Part D of form 2A. This includes metals that -are
not normally monitored through your NPDES permit.
➢ Analyses for total phenolic compounds and hardness.
➢ Analyses for all of the volatile organic compounds listed in Part D.
➢ Analyses for all of the acid -extractable compounds listed in Part D.
➢ Analyses for all base -neutral compounds listed in Pan D.
2. Conduct four toxicity tests for an organism other than Ceiodapbnia and submit results with your renewal
application. The tests should be conducted quarterly, with samples collected on the same day as your
current toxicity test. Call the Aquatic Toxicology Unit at [phone] for guidance in conducting the
additional tests.
These additional analyses must accompany your permit renewal application, or any request for a major permit
modification. The Division cannot draft your permit without the additional data. Any data submitted cannot be
over 41/z years old, and must account for seasonal variation (samples cannot be collected during the same season
each year if collected over multiple years).

If your permit already contains a requirement for an annual effluent pollutant scan, additional scans are not
required [provided you have conducted at least 3 scans prior to submitting your application].
If any wastewater discharge will occur after the current permit expires, this NPDES permit must be renewed.
Discharge of wastewater without a valid permit would violate Federal and North Carolina law. Unpermitted
discharges of wastewater could result in assessment of civil penalties of up to $25,000 per day. If all wastewater
discharge has ceased at your facility and you wish to rescind this permit, contact Vanessa Manuel of the Division's
Compliance Enforcement Unit at [phone], extension 532. You may also contact the Raleigh Regional Office
at [phone] to begin the rescission process.

Describe Problems/Observations
Our technical assistance visit was in response to a request from Mr. Myrl Nisely of the
Raleigh Regional Office who conducted a visit to this same facility on 6/23/2003. The
purpose of his visit was to evaluate their system and operational practices with regards to
high flow events and associated turbidity problems with their plant effluent (see attached
"Warrenton Recon."). We were met by Mr. Perkinson and given a tour of the facility
starting at the headwork's, then working from the effluent backwards through the
treatment process.
On this day, one of the clarifiers was not operating, isolated and drained due to a leaking
centerwell seal which was ordered, to be delivered anyday and replaced, at which time it
would be placed back in service. It was suggested in the future when leaving the clarifier
offline for an extended period of time, if possible, fill it with water to stop the excessive
rusting observed during this visit as well as maintaining proper moisture for any other
seal etc. that may dry and subsequently leak. Mr. Perkinson agreed and stated that in the
future every effort would be made to follow this suggestion. The effluent of the two
oxidation ditches is straight to its associated clarifier with one effluent valve for each
ditch and a cross -connecting pipe with a single isolation valve to allow for operation of
one ditch with either of the two, or both clarifiers. On this visit and as mentioned in
Myrl's report, one ditch was operational and the other was down and full of septic sludge,
the other ditch was operational. The offline clarifier mentioned above was for the
operational ditch, so the ditch effluent was directed to the other clarifier. This was
putting backpressure on the isolation valve for the offline ditch, which was leaking by
and allowing activated sludge to enter the offline ditch and contribute to the existing
sludge problem. It was suggested that Mr. Perkinson contact someone within the city

utility department and acquire an inflatable line plug to stop this flow. Mr. Perkinson
agreed and stated he would start that process ASAP. Mr. Perkinson stated that normal
practice was to use the offline ditch as equalization during high flow events in
conjunction with a reduction of RAS flow to prevent solids washout. This statement with
regards to reducing the RAS flow rate is contradictory to what was stated in Myrl's report
and is probably a result of Myrl's visit and it is suggested this practice continue. Using
the offline ditch as equalization, although not designed as such nor desired, may be
continued but should be managed better with every effort made to return its contents
ASAP so as to minimize septicity and subsequent solids buildup. Initial visual
observation of the mixed liquor in the operational ditch was consistent with the color of
old sludge. This was later confirmed in the laboratory with a settleability test in which
the solids settled to 180ml in 1000m] in the first 5 minutes and 150 by the end of the test
(30 min) with numerous amounts of straggler floc left suspended. When asked about
their wasting practice, Mr. Perkinson stated they wasted regularly and during our tour a
log was presented. This log was not complete in that it did not have the actual totals per
waste event noted. As noted in Myrl's report, wasting was conducted until reaching the
top drain with no emphasis placed on the pounds of solids removed. It is suggested that
in the future a MLSS be conducted on the RAS flow and flow volumes recorded to
establish solid removal volumes for future process control. When Mr. Perkinson was
asked what process control method they used he stated that it was basically a MLSS
method with a desired concentration for summer and winter. It was suggested that he
start using MCRT in conjunction with MLSS and establish a trend or correlation between
the two and maybe in the future he may even want to start using MCRT solely. Don
asked for the operating manuals for the plant, located the original design figures for
MCRT and calculated MCRT using some "rough" MLSS values and it was suggested
that based on those figures that they could possibly operate with much less MLSS. It was
suggested that in the future Mr. Perkinson adopt this process control method since it most
closely meshed with their existing methods and is also worth mentioning that Mr.
Perkinson has background in laboratory analysis which should enhance this. The
impression was Mr. Perkinson had "inherited" some process control practices from past
operators which were not ideal and that Mr. Perkinson should start new practices which
were more beneficial to both he and his facility.

One oxidation ditch was down, full of sludge going septic. Duckweed on top. In normal
times, one oxidation ditch is adequate. Ditch No.I is fitted with a mixer and flow is
controlled to provide anoxic zones for nutrient removal. Ditch No. 2 is not so fitted, so
when it is pressed into use, only nitrification is accomplished in that unit.
The digesters were full, waiting for Granville Farms. MLSS was estimated to probably
be about 35 —3600 mg/1 today because there is no room for wasting.
Clarifier blankets were 1.5 and 2', respectively out of a total depth of 12'.
Effluent was clear and free of foam.
ORC logbook continues to be on computer, without signatures. In the last CEI it was
pointed out that a bound logbook is a requirement.
There have been days where Q hits 5 MGD for a few hours, sometimes 3-4 times per day.
Ammonia levels are usually the parameter that goes out of control during upsets.
Phosphorus remains fine. There was a bad upset of NH3 at the end of April and first half
of May, 2003. A question was raised about what the enforcement will look like for this
episode.
It was explained that the plant wastes with fair regularity to maintain MLSS
concentration at about 2500 — 3000 mg/l. MLSS is measured twice per week. While
stated to be according to MLSS, in practice the wasting is done until the digester level
reaches the top drain. So the length of time and the impact on MLSS concentration
varies.

Process control is basically by MLSS concentration and an occasional SVI ("not run
daily'). Apparently blanket settling characteristics are not a problem, although this was
not explored in greater detail.
A study of clarifier and ORC logs for rainy days showed blankets rising rapidly. In times
of trouble (high Q), the staff increases clarifier return rates to pull the blankets down.
This helps at first, but eventually just adds to the hydraulic load on the clarifiers, helping
to "fluff' the blankets and blow them over the weirs. Though it seems counter -intuitive,
slowing the recycle rate often actually helps relieve the throughput in the clarifiers and
allows the blankets more time to compact.
Loss of solids from the clarifier obviously puts a big load on the sand filters. Once these
clog, the flow automatically bypasses the units to the creek. This accounts for why final
effluent is turbid at times.
Logs showed an uneven split to clarifiers as evidenced by blanket levels. One would ride
at 10 to 12 feet while the other was at 5 feet for days at a time.
In high flow times, the clarifiers were losing blankets, yet crews went home at 5 PM until
the next day. Were other options considered, such as the use of polymer? The only
additional response in the log was, in one case, the second ditch was put into service via a
call in at 5 AM.

Dear Mr. Mitchell:
Raleigh, North Carolina 27609
Our office issued a Notice of Violation (NOV) dated 5/23/03 to Warren County WWTP for
failing to achieve compliance with the facility's 76% chronic toxicity effluent permit limitation for
March 2003.
It has come to my attention that this NOV was issued in error; therefore, the 5/23/03 NOV issued
to Warren County WWTP for failing to achieve compliance with its 76% chronic toxicity effluent permit
limitation for March 2003 is hereby rescinded. The Division's toxicity compliance and enforcement
tracking databases have been modified to reflect this change.
I apologize for this oversight. If you have any questions concerning this letter, please contact

you should have any questions about your toxicity testing requirement, please contact Mr. Kevin Bowden with
the Aquatic Toxicology Unit at [phone] or another Unit representative at the same number.
➢ The pgrmittee is responsible for ensuring that toxicity testing is conducted according to the permit requirement
and that toxicity report forms are appropriately filed.
➢ The reporting of whole effluent toxicity testing data is a dual requirement. All toxicity test results must be
entered (with the appropriate parameter code) on your monthly Discharge Monitoring Report which is
submitted to:
North Carolina Division of Water Quality
Central Files
1617 Mail Service Center
Raleigh, NC 27699-1617
IN ADDITION
Toxicity test data (original "AT" form) must be submitted to the following address:
North Carolina Division of Water Quality

1621 Mail Service Center
Raleigh, North Carolina 27699-1621
➢ Toxicity test results shall be filed with the Environmental Sciences Branch no later than 30 days after the end
of the reporting period (eg, January test result is due by the end of February).
Toxicity test condition language contained in your NPDES permit may require use of multiple concentration
toxicity testing upon failure of any single quarterly toxicity test. If the initial pass/fail test fails or if the chronic
value is lower than the permit limit, then at least two multiple concentration toxicity tests (one per month) will
be conducted over the following two months. As many analyses as can be completed will be accepted. If your
NPDES permit does not require use of multiple concentration toxicity testing upon failure of any single
quarterly test, you may choose to conduct either single concentration toxicity testing or multiple concentration
toxicity testing per the Division's WET enforcement initiatives effective July 1, 1999. Follow-up multiple
concentration toxicity testing will influence the Division's enforcement response.
➢ Toxicity testing months are specified by the NPDES Permit, except for NPDES Permits which contain episodic
toxicity monitoring requirements (eg, if the testing months specified in your NPDES permit are March, June,
September, and December, then toxicity testing must be conducted during these months).
➢ If your NPDES Permit specifies episodic monitoring and your facility does not have a discharge from January 1-
June 30, then you must provide written notification to the Environmental Sciences Branch by June 30 that a
discharge did not occur during the first six months of the calendar year.
➢ If you receive notification from your contract laboratory that a test was invalidated, you should immediately

SUBJECT: NOTICE OF VIOLATION
Whole Effluent Toxicity (WET) Testing
Copper and Zinc Action Level Policy
NPDES Permit No. NC0020834
Warren County WWTP
Warren County
Dear Mr. Mitchell:
This is to inform you that a review of your toxicity self -monitoring report form for the month of
March 2003 indicates a violation of the toxicity limitation specified in your NPDES Permit. You should
undertake necessary actions to eliminate or reduce effluent toxicity to acceptable levels.
In addition, this correspondence contains important information on the Division's Copper and
Zinc Action Level Policy which is triggered by two or more toxicity limit violations that occur during
the toxicity testing calendar quarter specified by the toxicity testing special condition of your NPDES
Permit. Attachments addressing policy implementation and a copy of the Division's Toxicity Reduction
Guidance have been included with this Notice of Violation.
You should initiate follow-up toxicity testing upon a single WET test failure which occurs
during the toxicity testing calendar quarter.
Your facility is currently monitoring for copper and/or zinc and the data indicate that the levels
of copper/zinc in your effluent have the potential to cause an exceedance of the NC water quality action
level for this (these) parameter(s) in your receiving stream during low stream flow conditions. The
policy states that whenever a facility experiences two or more toxicity limit violations during a toxicity
testing calendar quarter, the NPDES Permit will be modified to include numeric limits for copper and/or
zinc UNLESS the permittee provides one or more of the following:
1. Instream measurements of dissolved metal during low flow conditions that demonstrate
compliance with the Action Level standard
2. A revision of the prospective permit limit using improved inputs that in concert with
existing or additional monitoring data demonstrates compliance with the Action Level
standard
3. Toxicity Identification Evaluation (TIE) results that definitively rule out copper and/or zinc
as causes of effluent toxicity
4. Demonstration by an alternative method approved by the Division and EPA that copper
and/or zinc is not the cause of toxicity

The Division has Ated your copper and/or zinc monitoring . The Division has also
developed a prospective NPDES permit limit based on your facility's instream waste concentration, the
copper and/or zinc action level criterion and a translator procedure. Based on this data your prospective
copper permit limit is 20 µg/L.
The permittee, upon experiencing two or more toxicity limit violations during a toxicity
testing calendar quarter must either provide DWQ with:
a) Written notification indicating acceptance of the prospective copper
and/or zinc permit limit. Notification is due within 30 days after the date of
the second WET Notice of Violation
DIO
b) Written notification indicating your choice of option(s) as noted on page
one of this correspondence. Notification is due within 30 days after the date
of the second WET Notice of Violation. DWQ approval of options 1-3
(previous page) is not necessary as the Division expects work to rule out
copper and/or zinc as causative effluent toxicants to begin immediately upon
the second WET permit limit violation.
Written notification (a or b above) shall be sent to:
North Carolina Division of Water Quality
Environmental Sciences Branch
Aquatic Toxicology Unit
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Please note that if you choose item b) above, you will be given nine months to submit
documentation that eliminates copper and/or zinc as causative effluent toxicants. Your final report
should be comprehensive and include all data used to support your conclusion(s). Should the data
indicate copper and/or zinc as the source of effluent toxicity or if the data are inconclusive as to copper
and/or zinc's role as a toxicity source, then the NPDES Permit will be reopened and the metal limits
specified above will be applied to the permit. The report is due nine months after the date of the second
WET Notice of Violation.
Three copies of the final report shall be submitted to:
North Carolina Division of Water Quality
Environmental Sciences Branch
Aquatic Toxicology Unit
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
You should consider submitting the above correspondence certified mail.
Failure to notify DWQ of your acceptance of a copper and/or zinc limit, failure to notify
DWQ of your option selection or failure to make acceptable demonstration to DWQ that copper
and/or zinc are not causative effluent toxicants within the stated time frames will result in
reopening of the NPDES Permit to include copper and/or zinc numeric limitations, as appropriate.
Please note that your actions to notify DWQ of prospective limit acceptance or to notify DWQ
of plan option(s) and subsequent submission of a plan are contingent upon two or more toxicity NPDES
permit limit violations occurring during a toxicity testing calendar quarter.

If the effluent is toxic, then we expect work to commence immediately with toxic effluent
samples. Failure to initiate work with toxic effluent samples during the study period is unacceptable and
will be considered a failure to make acceptable demonstration as cited above. We recommend a
minimum of three separate sampling events during the nine month period to definitively rule out copper
and/or zinc as causative effluent toxicants.
Also note that the WET limit will remain in your NPDES permit regardless of whether metals
are the source of effluent toxicity. The data resulting from your actions to disprove copper and/or zinc as
sources of effluent toxicity will determine whether NPDES Permit limits will be assigned for these
parameters. You are responsible for initiating actions to address these issues.
You may consider entering into a Special Order by Consent (SOC) with DWQ. A SOC provides
regulatory relief for specific NPDES permit limit violations and, if signed, will contain a requirement to
conduct a Toxicity Reduction Evaluation. The SOC will contain a compliance schedule, stipulated
penalties for failing to meet milestone activity dates and may contain upfront penalties to settle past
permit limit violations.

emergency situations. If there are currently any portions of the collection system that are inaccessible
by maintenance and emergency equipment please identify those in response to this letter. For each
identified section please provide a plan and schedule to establish accessibility- or an alternate method of
properly maintaining that portion of the system.
Below I have listed the items that may be of specific note to the Town. These items do not need to be submitted but
should be in place prior to receiving the permit. Please inform me if you have any questions or comments regarding
any of these items:
I. Please note that the permit will require a written contingency plan to be developed for each pump
station in case of pump failure. These plans should be available to staff at all times and should clearly
identify the steps they are to take in case of a pump failure.
2. I've enclosed an outline of all inspections, logs and record keeping that will be required in the permit.
We discussed record keeping during our meeting. Currently the Town has records of work orders and
has begun pump station inspection records. There will be record -keeping that will have to be added to
the existing program and some existing logs and/or inspections may need to be modified to include all
items to be inspected/tested as required by the permit.
3. You noted that the Town is currently working towards development of a detailed mapping of the
collection system. Please note that a minimum of 10 percent of the system must be mapped each year.
Items required on the map are listed in Condition 111.3 of the attached permit.
4. The Division of Water Quality highly recommends fencing around pump stations to restrict
unauthorized entry whenever possible. At a minimum all components of pumps stations must be
restricted. This includes locking all wetwell and drywell covers, locking all power and control boxes.
As mentioned above. I am attaching a template of the wastewater collection system permit. It is essential that your
staff review this document carefully again and make note of any conditions not already discussed in this letter that
will be problematic for the Town of Warrenton. Please submit a list of any Conditions not already discussed with
your response to the letter.
Please be aware that you are responsible for meeting all requirements set forth in North Carolina rules and
regulations. Any oversights that occurred in the review of the subject application package are still the responsibility
of the applicant. In addition, any omissions made in responding to the above items may result in future requests for
additional information.
Please reference the subject application number when providing the requested information. Two copies of all revised
and/or additional documentation should be submitted to my attention at the address above. Please note that failure to
provide this additional i von on or before the above requested date may result in your permit being issued

Dear Mr. Smiley:
The Non -Discharge Permitting Unit has conducted a preliminary review of the subject permit application package.
�,�.�r,ste,� -4-b tltSlo3
Below I have listed the items that must be submitted in response to this letter. Please submit these items in triplicate
to my attention at the address below by Decen1b8r2t-2ffl2'. I will then discuss other issues that are of importance
regarding the collection system permit, but do not require a written response. Finally, I am also attaching a template
of the wastewater collection system permit. It is essential that you and town staff members review this document
carefully and make note of changes to your current program that will need to be made, as well as making note of any
conditions not already discussed in this letter that will be problematic for the Town.
If after reviewing this letter and the enclosed template permit, you and/or your staff would like to discuss the
permitting process or the permit with the Division of Water Quality, I would be very happy to schedule a time to
come to Warrenton for a meeting.
The additional information to be submitted are itemized below:
In order to meet Condition I.2 of the permit. please provide a list of collection lines that are currently
identified as having inadequate capacity and likely to have Sanitary Sewer Overflows (SSOs) until
rehabilitated or replaced. With this list must be submitted documentation (evaluations by consultants.
spill reports etc.) to show how it was determined that the specific section of collection line has capacity
inadequacies (you may refer to documents already submitted with your application). You must also
provide a scheduled date for when each line will be rehabilitated or replaced to solve the current
problem. The scheduled dates should be reasonable and you should be able to provide justification for
each date.
2. Per permit condition I.10, each pump station MUST have BOTH audible and visual alarms present and
working. UNLESS there is a telemetry SCADA system with automatic poling for signal at the pump
station. Pump stations without telemetry SCADA systems or visual and audible alarms must
immediately be retrofitted. The list of pump stations that was provided with the permit application
indicates that at least one pump station is not currently provided with all required alarms. Please
provide a date in the near future when the F&M pump station will be fitted with an audio alarm to
accompany the existing visual alarm.
3. The locations of all high priority lines will be referenced in your collection system permit. Therefore it
is necessary to provide this information in the form of a written list. Please provide a written list (the
identifier used can be any that is clear to the Town, such as from manhole #20 to manhole #30 or, along
Smith St from James St to Oak St, etc). Please note the Division's definition of a high priority line
when developing this list: Any aerial line. sub -waterway crossing, line contacting surface waters,
siphon, line positioned parallel to streambanks that are subject to eroding in such a manner that may
threaten the sewer line.

Dear Ms. Homewood:
I had submitted this information at an earlier date therefore I am sending this response
certified mail. I apologize for the delay.
In response to item #1, your letter dated November 21, 2002:
We do not have collection lines having inadequate capacity and likely
to have SSOs.
Item #2:
We have installed both audible and visual alarms at F & M lift station and
the Detention Center lift station. Currently all lift stations not having telemetry
are equipped with working audible and visual alarms.
Item #3:
The high priority lines in our collection system are as follows:
From manhole #5 to manhole #15 this is the area behind the WWTP
to SR 1001.
From manhole #25 to manhole #30. #25 is just south of Ridgeway
Street - #30 is behind Connell Subdivision.
From manhole #105 to manhole #110. #105 is at the end of the
Cochran Furniture sewer line - # 110 is at the intersection of Warren
and Bute Street.
From manhole # 13 8 to manhole #140. # 13 8 is the first manhole in
John Riggan's pasture - #140 is the last manhole leading to
the John Riggan lift station. #140 is actually in the creek.

Aerial lines are as follows:
Gravity line from manhole #9 to #38
Gravity line from manhole #13 to #56
Gravity line from manhole #105 to #106
Gravity line from manhole #109 to #110
Gravity line from manhole #120 to #121
Item #4, Right-of-ways inaccessible:
Sewer line from old hospital to Peck Manufacturing has one manhole in
a swampy area Line can be cleaned from downstream direction.
Sewer line behind Cochran Furniture needs two creek crossings to be
accessible. This work is scheduled for July 2003.
Possumquarter Creek sewer Ime right-of-way was cleared March 12,
2003.
All items in your letter have been reviewed and appropriate action is being taken. We are
very excited about receiving a grant for our mapping system and should have that in
place within the next two months.
Again, I apologize for the delay in getting this response to you. If you have any
questions feel free to contact me.

Dear Mr. Gardner:
On February 3, 2003, Mr. Myrl Nisely of the Raleigh Regional Office conducted an annual
compliance inspection of the Regional WWTP facility. The assistance provided by Mr. Bill
Perkinson was greatly appreciated. Findings during the inspection were 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.
Seven influent lift stations are under the care of the Warrenton Public Works Department.
The plant was clean, nicely landscaped and well cared for. A backup generator was
demonstrated to be in working order. It is tested weekly.
2. The influent grit chamber was being bypassed, and has been for about a month to clean out
grit and repair a pipe leak. At present flows, the effectiveness of this chamber is considered
marginal by the operating staff.
3. One of the three influent lift pumps had been replaced very recently, but had problems with
an air leak that caused loss of prime. Repairs are expected within a few days.
4. On the day of inspection, only one oxidation ditch and one secondary clarifier were in use.
Maintenance was being done on the clarifier to upgrade the scrapers and to clear siphon
pickup pipes. The ditch was full of mixed liquor on hold because of excessive flow in recent
days from rain and significant I & I. The active clarifier showed modest levels of buildup on
the V-notch weirs and trough because weekly cleaning had been delayed by recent heavy
rains and cold weather. There was one foot of sludge in the clarifier, well under the 1/3
depth guideline.
5. The sand filters and chlorine contact chamber were exceptionally clean and free of growth.
6. One aerated digester was 1/3 full, the other about 3/4 full and being decanted. Sludge
disposal is handled by Granville Farms land application. Lime is stored in a silo for pH
adjustment and waste sludge treatment.

7. The effluent was clear and free of foam and solids. Access to the discharge pipe was readily
available, although the December ice storm had brought down several limbs right over the
discharge point. These should be removed as soon as possible. Reminder: weeds are to be
controlled during the growing season.
8. A check of the flow meter against a staff gage agreed with each other almost exactly.
Samplers were operating well. The effluent sampler was flow proportional, with a
refrigerator temperature of 2° C.
9. The laboratory runs fecals and field tests, and was certified in December, 2002. No
additional field certification will be needed. The fecal incubator had a temperature of 440 C.
Chemical bottles were appropriately labeled with dates received, opened and expiration date.
10. Review of self monitoring DAM reports for March and September, 2002 showed consistent
reporting of results. Chains of custody were in order.
11. The ORC logbook is presently being kept on computer. Therefore, no signature exists to
document the declaration that a plant visit was made. The Division requires the use a bound
logbook as the official record.
12. A review of self monitoring DMR reports for the past year showed limit violations in
September, 2002 for BOD weekly and monthly averages and ammonia monthly average.
Enforcement will be taken on these excursions.
This wastewater treatment plant is running well. Mr. Nisely was pleased to meet both Bill
Perkinson and Kenny Champion. If there are any questions or comments, please contact Myrl
Nisely at [phone].

Dear Mr. Matthews:
P. O. Box 281
Warrenton, NC 27589
Q�
This morning I spoke with Kevin Bowden of NCDENR \ DWQ by phone concerning problems that we
have encountered with chronic toxicity testing scheduled for our plants effluent in December 2002.
Originally this was scheduled for 12-10-02 and 12-13-02. The 12-05-02 ice storm caused our plant to
be without electrical power from 12-05-02 to 12-11-02. Also, the laboratory we use for our testing,
Tritest, Inc. was down for some time immediately after the ice storm. The toxicity testing was
rescheduled for 12-31-02 and 01-03-02. Due to problems encountered with our effluent composite
sampler on 12-31-02, we were forced to abort this particular test.
The toxicity testing has been rescheduled for 01-07-02 and 01-10-02. We apologize for the delay in
performing this test.
We appreciate your direction and assistance in connection with this matter. Please advise us if we
need to provide any further information.
Sincerely,
William R. Perkinson
