• Permit NC0020389
A. (3) CHRONIC TOXICITY PERMIT LIMIT (Quarterly)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or
significant mortality to Ceriodaphnia dubia at an effluent concentration of 90%.
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 January, April, July and October. 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:
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 NC0020389
A. (4) CALCULATION OF TOTAL NITROGEN LOADS _
a. The Permittee shall calculate monthly and annual TN Loads as follows:
i. Monthly TN Load (pounds/month) = TN x TMF x 8.34
where:
TN = the average Total Nitrogen concentration (mg/L) of the composite samples collected during the month
TMF = the Total Monthly Flow of wastewater discharged during the month (MG/month)
8.34 = conversion factor, from (mg/L x MG) to pounds
if. Annual TN Load (pounds/year) = Sum of the 12 Monthly TN Loads for the
calendar year
b. The Permittee shall report monthly Total Nitrogen results (mg/L and pounds/month)
in the discharge monitoring report for that month and shall report each year's
annual results (pounds/year) in the December report for that year.
A. (5) ANNUAL LIMITS FOR TOTAL NITROGEN
a. Total Nitrogen (TN) allocations and TN Load limits for NPDES dischargers in the
Neuse River basin are annual limits and are applied for the calendar year.
b. For any given calendar year, the Permittee shall be in compliance with the annual TN
Load limit in this Permit if:
i. the Permittee's annual TN Load is less than or equal to said limit, or
ii. the Permittee is a Co-Permittee Member of a compliance association.
c. The TN Load limit in this Permit (if any) may be modified as the result of allowable
changes in the Permittee's TN allocation.
i. Allowable changes include those resulting from purchase of TN allocation from
the Wetlands Restoration Fund; purchase, sale, trade, or lease of allocation
between the Permittee and other dischargers; regionalization; and other
transactions approved by the Division.
ii. The Permittee may request a modification of the TN Load limit in this Permit to
reflect allowable changes in its TN allocation. Upon receipt of timely and proper
application, the Division will modify the permit as appropriate and in accordance
with state and federal program requirements.
iii. Changes in TN limits become effective on January 1 of the year following permit
modification. The Division must receive application no later than August 31 for
changes proposed for the following calendar year.
iv. Application shall be sent to:
NCDWQ / NPDES Unit
Attn: Neuse River Basin Coordinator
Mail Service Center
Raleigh, NC 27699-1617
d. If the Permittee is a member and co-Permittee of an approved compliance
association, its TN discharge during that year is governed by that association's group
NPDES permit and the TN limits therein.
i. The Permittee shall be considered a Co-Permittee Member for any given calendar
year in which it is identified as such in Appendix A of the association's group
NPDES permit.
ii. Association roster(s) and members' TN allocations will be updated annually and
in accordance with state and federal program requirements.

• Permit NCO020389
iii. If the Permittee intends to join or leave a compliance association, the Division
must be notified of the proposed action in accordance with the procedures
defined in the association's NPDES permit.
(1) Upon receipt of timely and proper notification, the Division will modify the
permit as appropriate and in accordance with state and federal program
requirements.
(2) Membership changes in a compliance association become effective on January
1 of the year following modification of the association's permit.
The TN monitoring and reporting requirements in this Permit remain in effect until expiration of
this Permit and are not affected by the Pennittee's membership in a compliance association.
A. (6) LAGOON FREEBOARD HEIGHT REQUIREMENT
A minimum of 2 feet of freeboard height must be maintained in the lagoons (currently used for
equalization/sludge holding). A staff gauge must be placed in each lagoon and the height
recorded daily.

A. (7) EFFLUENT POLLS WANT SCAN • Permit NC0020389
The Permittee shall perform an annual Effluent Pollutant Scan for all parameters listed in the attached table. The
analytical methods shall be in accordance with 40 CFR Part 136 and shall be sufficiently sensitive to

STANDARD CONDITIONS FOR NPDES PERMITS
Section A Definitions
2/Month
Samples are collected twice per month with at least ten calendar days between sampling events.
3/Week
Samples are collected three tines per week on three separate calendar days.
Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33 USC 1251, et. seq.
Annual Averagg
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform, the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
Dwass
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.
Calendar Dav
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.
Calendar Out rter
One of the following distinct periods: January through March, April through June, July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 ml in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time
interval between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically.
Composite samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: 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
(3) Variable time/constant volume: 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 preset gallon interval between sample collection feed at no greater than 1/24 of the
expected total daily flow at the treatment system, or
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at
a constant time interval. This method may only be used in situations where effluent flow rates vary
less than 15 percent. The grab samples shall be taken at intervals of no greater than 20 minutes apart
during any 24-hour period and must be of equal size and of no less than 100 milliliters. Use of this method
requires prior approval by the Director.

system in number of days. However, the interval between effluent grab samples may not exceed six hours nor
the number of samples less than four during a 24-hour sampling period.
Continuous flow measurement
Flow monitoring that occurs 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.
Daily DischaM
The discharge of a pollutant measured during a calendar day or any 24hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. The "daily discharge" concentration comprises the mean
concentration for a 24hour sampling period as either a composite sample concentration or the arithmetic mean of all
grab samples collected during that period. (40 CFR 122.3)
Daily Maximum
The highest "daily discharge" during the calendar month.

Re: W WTP Violations, LV-2014-0099, 0100, and 0 10 1
Town of Benson, North Carolina
Dear Mr. Smith:
TOWN MANAGER
MATT ZAPP
TOWN CLERK
CONNIE M. SORRELL
FINANCE DIRECTOR
VACANT
TOWN ATTORNEY
R. ISAAC PARKER
This letter is being sent in response to the letter the Town received dated March 31, 2015
from S. Jay Zimmerman that denied the Town's request to Remit Civil Penalties levied
for limits violations LV 2014-0099, 0100, and 0101 and the subsequent meeting held on
May 14, 2015 in which representatives from the Town, DWQ, and The Wooten Company
were present.
It is the Town's understanding that our request for remission of penalties was denied, at
least in part, due to the fact that our request did not lay out a plan that was specific
enough in nature in how the Town will work to correct the inflow and infiltration (I/I)
problem in the wastewater collection system that we believe lead to the subject violations
at the W WTP. While the Town described the four phase approach that is being
undertaken, the schedule of these actions were not specific enough to demonstrate that
the Town is working at an acceptable pace to correct these problems.
At the meeting held on May 14, the Town described that several actions have already
occurred or are underway. These actions are as follows:
Phase I (mapping): received Rural Center funding and Town completed this phase in
March 2014.

Mr. Danny Smith
June 8, 2015
Page 2 of 3
Phase II — Smoke Testing: The Town determined that our staff could assist Rural Water
Association in this phase. To date, 15-20% of the system has been smoke tested. As a
result of the testing, the Town has completed repair of 28 broken clean out caps, and 14
manholes that showed deficiencies. The objective is to "find and fix" as many inflow
sources as possible, as well as qualify areas that should be followed up on with the next
phase of cleaning and CCTV inspection. In addition to the field work and repairs, the
Town has invested heavily in human resources to provide redundancy for all certified
positions such as operators.
Moving forward, the Town plans to continue the four phase approach to correcting the I/I
problems but we will be more aggressive with our schedule to the maximum extent
possible. The schedule of these actions will be as follows:
• Complete remaining smoke testing: October 31, 2015. To meet this schedule, the
Town will either contract out services or hire additional staff.
• Complete CCTV for critical areas from Smoke Testing: December 31, 2016.
Depending on the problems found, this cost may need to be spread across two
budget years.
• Complete Capital Improvements Plan from results of field work: June 30, 2017.
As field work reveals needed maintenance activities that Town staff can complete such as
clean out caps, manhole cover replacement, etc. these items will be completed. For the
larger scale repairs such as trenchless sewer rehabilitation, sewer replacement, and point
repairs, the Town will begin applying for funding using the Capital Improvements Plan as
leverage. Funding sources for repairs will include CWSRF, USDA — Rural
Development, and CDBG funding. As soon as we can evaluate supporting data, the
Town will make effort to secure any grant funds possible before pursuing low interest
loans. It is likely that a combination of grants and loans can be secured to help the Town
complete the needed work. As stated before, remission of the assessed penalties will
allow the money that would pay the penalties to be used for smoke testing and CCTV
work. Therefore, the Town continues its request to remit the penalties and allow the
Town to better invest the money directly into repair of our infrastructure.
We appreciate your consideration of this request. If you should have any questions or
require additional information, please do not hesitate to contact me.
Sincerely,
Stephen Phillips
Town of Benson

Subject: RE: Meeting
Mr. Phillips,
Thanks for meeting with us yesterday, May 14, 2015.
The letter you that you received on April 171h from DWR's Central Office explained remissions recommendation decision
and that the Division will hold the penalty payment expectation in abeyance for 90 days of your receipt of the letter or
until July 17, 2015 (which is 90-days after you received the correspondence) .
In our meeting yesterday we discussed several issues regarding Inflow and Infiltration. Accordingly, please
provide Raleigh Regional Office a detailed schedule of actions that will be taken by the Town of Benson to
identify and address/abate the Town's I&I issues, including the identification of funding source(s). Please submit
this, or an application requesting a Special Order by Consent (SOC) to the Division within 70 days of receipt of
the letter you received, or by June 26, 2015. (if the town is proposing to submit an SOC application and
additional time is needed for application submittal, please call me to discuss.) Information for submitting an
application for an SOC may be found here: link
After the RRO receives the abovementioned response/schedule or an SOC application, the RRO will revisit remission
recommendation and provide the new remission's recommendation to the DWR's Central Office staff. At that time our
Central Office will provide you a new correspondence indicating payment expectations and your remaining
appeal/remission options before EMC enforcement subcommittee, as appropriate.
Therefore, there is not a 30 day payment expectation in response to the request to remit civil penalties per letter dated
March 31, 2015 (Town of Benson receipt date is April 17" ). Rather, this issue will be revisited in late July and a new
correspondence will be provide to you that will clearly communicate: 1) remissions decision, 2) penalty payment
options, and 3) oral presentation options before Environmental Management Commission Enforcement Subcommittee.
Please let us know if you have any questions.
Thanks

ROLE OF THE CONSTRUCTION INSPECTION GROUP WIG)
1. Conduct periodic inspections of the project.
2. Review change orders for necessity and reasonableness to determine eligibility for loan
funding.
3. Purpose:
a. To assure that the overall objectives of the loan are realized.
b. To assure that the loan and project will be administered in accordance with State
regulations.
c. To advise and offer assistance to the Loan Recipient.
d. To ensure contract compliance and construction in accordance with the approved
contract documents.
CIG INSPECTIONS
Prior notice will be given; however, unannounced inspections may also be conducted.
2. Inspections will be primarily focused on the project construction but will also act on behalf
of Infrastructure Finance Section (IFS) for loan administration issues (as necessary).
3. During inspections, CIG will usually review all shop drawings, submittals, inspector's field
reports, as -built drawings, revised construction schedules and records of testing of
materials and equipment, and discuss pending or executed change orders for completeness
and accuracy.
4. The Division of Water Quality (DWQ) requests that all equipment and materials on job
site are properly stored, stockpiled, and protected. The job site is to be maintained in an
acceptable manner.
5. Safe working conditions should be maintained at all times. CIG will discuss safety
violations which are potentially life endangering or threatening serious injury. If
necessary, CIG will take prompt action to notify State and OSHA regional representatives
of any noted conditions.
6. Results of the inspection will be discussed at the job site upon completion of the inspection.

7. Formal copies of the inspection report will be sent to the Loan Recipient, A/E and other
parties, if so requested.
8. CIG prefers to accompany the A/E on the final punch list inspection to avoid the situation
where both the A/E and CIG provide a final punch list of deficiencies to the contractor.
CHANGE ORDERS
The Loan Recipient, hereafter referred to as Recipient, should notify the DWQ prior to
commencement of any change order work, except for emergency situations, that change the
scope of the project.
2. Recipient must obtain prior DWQ approval for any change orders in excess of $100,000 or
any change orders that would necessitate an increase in the loan amount.
Recipient should submit two (2) properly executed (original signatures) change orders to
DWQ. Change order forms should indicate the Federal or State loan project number, the
correct change order number, name of contractor, contract number, and the dates the
change order was signed by each party. If additional information is requested by the State,
a response is required within two (2) weeks, or the change order will be returned without
further or final action.
4. A complete detailed justification and clear description must be submitted with each change
order to identify the need for the change. For any requested time extensions, the submittal
shall include justification and proper documentation.
5. Copies of new or revised contract drawings and/or specifications must be submitted with
each change order, when appropriate.
6. Unless previously agreed unit prices are used, complete records of price negotiations shall
be submitted with each change order. This should include such items as: a copy of the

The change order checklist should be completed and submitted with each change order. A
copy of the checklist is attached.
8. Change orders will not be approved until the above backup documentation is submitted.
Work in place required by a non -State approved change order shall not be included in a
contractor's partial payment request until the change order is approved.
9. Once the Recipient signs a change order, the Recipient is obligated to the Contractor. The

recommends submittal of unexecuted change orders to provide the Recipient with a
preliminary eligibility determination.
10. Quantity overruns on unit price contracts will not be reimbursed for the project until a
change order is submitted and approved to address the overruns.

The inspection began in the treatment plant office. All paperwork was well organized and
easily accessible. Discharge Monitoring Reports were reviewed for compliance with permit
limits and monitoring requirements. Chain of custody records were available and found to be
in order. The laboratory is state certified and performs the majority of permit required
parameters. Contract lab - EnvironmentOne, performs the remainder of the parameters
required by the permit, toxicity is performed by Ameritech.
4. Maintenance and housekeeping was found to be good. The mechanical and manual bar screens
were in acceptable condition, and were demonstrated during the inspection. The grit removal
system was functioning properly and without excessive odor. Debris is removed as needed
and taken to the landfill.
S. Secondary clarifiers #2, #4 and #5, were functioning properly and were free of weir blockages
and showed no sign of short-circuiting. #1 and #3 were offline, due to low flow conditions.
The performance of the plant was not affected by these clarifiers being offline. The sludge
blanket ranged from 1'-2', which is within the acceptable range of sidewall depth.
6. Biological nutrient removal is conducted at the facility, no chemical feed is required.
7. The #4 tertiary filter continues to be off-line due to the necessity of replacing a broken
hydrocone base. This was noted in the last inspection dated 7.13.11. Please provide a
timeline for the replacement of the hydrocone base and when the tertiary filter will be
back in service.
8. The chlorination and de -chlorination systems appeared to be functioning properly.
9. The three oxidation ditches appear to have adequate capacity with no objectionable odor. The
central ditch acts as an anoxic zone, which splits and flows to the aerated ditches on either
side. The DO for the outside ditches is 1.5, and for the central ditch is <.05.
10. Standby power, consisting of a permanent generator, is available and is tested as requred. The
generators have the capacity to run the waste water treatment plant effectively.
11. The effluent pipe discharges to Hannah Creek, adjacent to the facility. The effluent appeared to
be clear. The receiving water is free of foam and other debris.
The Benson Wastewater Treatment Plant appears to be a well run facility with few problems cited,
during this inspection. Please respond back to this office within 30 days of the receipt of this letter,
concerning the issue noted in bold in item #7. Please continue your diligence in the proper

Performance Annual Report
I. General Information
Facility Name: Benson Wastewater Treatment Plant Responsible Entity: Town of Benson
Contact Person: Martin Morris Applicable Permit # NCO020389
Telephone # [phone] Telephone # [phone]
Description of Treatment Process: The Benson W WTP uses modified extended aeration, mechanical and biological
processes to treat the raw wastewater entering the plant. The raw wastewater enters the plant from town through two 16 inch
sewage mains and goes through a mechanical bar screen which removes floating material then to a grit chamber which slows
the flow to less than 1 foot per second which allows any heavy materials (sand & organics etc.) to be removed. The flow
then goes through a parshall flume measuring device, a set of screw pumps and into three large oval oxidation ditches, with
a volume of 618,000 gallons each, where oxygen is added by means of surface rotors. The oxygen promotes the growth and
reproduction of natural bacteria and other organisms, which reduce the pollutants to inert solids. The mixed water and solids
then go to five (5) clarifiers in which the solids settle to the bottom by gravity and then removed. The clarified water is then
pumped to five (5) multi -media gravity filters, which remove any residual solids after which the water is disinfected with
gaseous chlorine then released into Hannah Creek after samples are taken and analyzed as required by our NPDES Permit.
