Cary takes pride in protecting the environment by providing exceptional wastewater
collection and treatment services for which we have been recognized by our peers as
industry leaders. The top priority for our wastewater utility is to provide safe and reliable
wastewater collection and treatment services that are properly operated and maintained
to exceptional professional standards that meet and surpass all federal and state
requirements for environmental and community protection. We appreciate the opportunity
to provide additional justification for remission of the $536.57 civil penalty assessment.

Request for Remission of Civil Penalty January 12, 2023
Pursuant to NCGS 143B-282.1(c) remission of a civil penalty may be granted only when
one or more of the following 5 factors apply:
a. One or more of the civil penalty assessment factors in NCGS 143B-282.1(b) were
wrongfully applied to the detriment of the petitioner
b. The violator promptly abated continuing environmental damage resulting from the
violation
c. The violation was inadvertent or a result of an accident
d. The violator had not been assessed civil penalties for any previous violations
e. Payment of the civil penalty will prevent payment for the remaining necessary
remedial action
June 6, 2022 — 4100 Cary Oaks Drive, Incident #202200880
We believe that factors b, c, or d apply and should be considered in reviewing the civil
penalty assessment and our associated request for remission.
Remission Factor b: The violator promptly abated continuing environmental
damage resulting from the violation.
Cary responded quickly to stop the sewer spill. Once onsite, staff immediately removed
the blockage from the 10-inch sewer line causing the SSO and promptly began cleaning
up the spill. A temporary dam was constructed downstream in Camp Branch beyond the
location where the sewer spill advanced. Pumps were set up and the stream was flushed
with 66,500 gallons of dechlorinated potable water. The combined wastewater and
flushing waters were pumped into the sanitary sewer system for advanced treatment.
Cleaning and flushing occurred for approximately 12 hours to help restore the stream.
Remission Factor c: The violation was inadvertent or a result of an accident
The sewer spill was inadvertent and accidental as determined by a review of the actual
cause of the SSO. The cause of the SSO was associated with a 10-inch sewer line
cleaning that was performed on June 8, 2022 by Cary staff in preparation for a planned
sewer line maintenance and repair project. The sewer line was being proactively cleaned
for a planned pump station force main pigging/cleaning operation and the associated
replacement of an air release valve and manhole. Cleaning activity removed debris from
the 10-inch gravity sewer line, and debris strainers and vacuum trucks were used to
collect the debris. Unfortunately, some gravel and debris traveled downstream to an
adjoining sewer line and manhole, resulting in an accidental obstruction that subsequently
contributed to the inadvertent backup and SSO.
Cary takes a proactive and predictive approach to the operation and maintenance of our
collection system. With the planned cleaning operation performed to support sewer
system rehabilitation, it was completely inadvertent and an accident that a spill resulted
from those proactive efforts and was not caused by neglect, or the lack of Cary
maintaining our collection system.

Request for Remission of Civil Penalty January 12, 2023
Remission Factor d: The violator had not been assessed civil penalties for any
previous violations
Cary has not been assessed any civil penalties for any collection system (WQCS00013)
violations within the last 5-years or sewer blockages and/or SSO caused by an
inadvertent SSO caused by proactive sewer maintenance. Cary's extensive sewer
collection system maintenance records do not identify manholes SP76011033,
SP76011035 or the associated sewer line segment to have any past or repeated
compliance issues.
June 22, 2022 — 8921 Holly Springs Road, Incident #202200983
We believe that factors b, c, and d apply and should be considered in remising the civil
penalty assessment.
Remission Factor b: The violator promptly abated continuing environmental
damage resulting from the violation.
Cary responded quickly to stop the sewer spill. Once onsite staff immediately removed
the concrete construction debris blockage from the 8-inch sewer line causing the SSO
and promptly began cleaning up the spill. A temporary dam was constructed downstream
in the unnamed tributary that leads to Camp Branch beyond the location where the sewer
spill advanced. Pumps were set up and the stream was flushed with 17,200 gallons of
potable water. The combined wastewater and flushing waters were pumped into the
sanitary sewer system for advanced treatment. Cleaning and flushing occurred for
approximately 1.5 hours to help restore the stream.
Remission Factor c: The violation was inadvertent or a result of an accident
The sewer spill was inadvertent and accidental as determined by a review of the actual
cause of the SSO. The cause was associated with a piece of broken concrete that was
found in the 8-inch sewer line that resulted in a backup and SSO. Cary was not able to
determine if the construction debris was inadvertently placed in the sewer system or fell
into the sewer system leading to the blockage. Eighty-eight minnows were affected by the
sewer spill and cleanup efforts. Ambient air temperatures at the time the spill occurred
were at approximately 100 degrees which is believed to be a contributing factor in the
unfortunate fish kill. A couple of slow moving or stagnant pools of water in the unnamed
tributary combined with the high temperatures, overflow, and stream cleaning contributed
to the inadvertent stream conditions and fish kill.
Remission Factor d: The violator had not been assessed civil penalties for any
previous violations
Cary has not been assessed any civil penalties for any collection system (WQCS00013)
violations within the last 5-years or sewer blockages and SSO caused by an inadvertent
SSO caused by construction debris that led to a blockage. Cary's extensive sewer
collection system maintenance records do not identify manhole SP76011061 or the
associated sewer line segment to have any past or repeated compliance issues.

Request for Remission of Civil Penalty January 12, 2023
We appreciate the opportunity to provide additional information and our perspective on
the unfortunate sewer spills. These instances are the only sewer spills that have occurred
in the specific areas identified within our collection system and immediate action was
taken to prevent an SSO reoccurrence. We respectfully request that NCDEQ remove the
$536.57 civil penalty assessment by further evaluating our spill response, the proactive
system maintenance Cary performs, the cause of the spills, and Cary's exceptional record
of wastewater collection system compliance. If we can answer any questions or provide
any additional information, please feel free to contact Mr. Donald Smith, Wastewater
Collection System Manager at [phone].

such a request must be accompanied by a waiver of your right to an administrative hearing and a stipulation and
agreement that no factual or legal issues are in dispute. Please prepare a detailed statement that establishes why you
believe the civil penalty should be remitted and submit it to the Division of Water Resources at the address listed below.
In determining whether a remission request will be approved,the following factors shall be considered:

applied to the detriment of the petitioner;
(2) whether the violator promptly abated continuing environmental damage resulting from the violation;
(3) whether the violation was inadvertent or a result of an accident;
(4) whether the violator had been assessed civil penalties for any previous violations; or

Cary Collection System
Wake County
Dear Mr. Revels:
A review has been conducted of the self-reported Sanitary Sewer Overflows (SSO's) 5-Day Report/s submitted by
Town of Cary. The Division's Raleigh Regional Office concludes that the Town of Cary violated Permit Condition I
(2) of Permit No. WQCS00013 by failing to effectively manage, maintain, and operate their collection system so
that there is no SSO (Sanitary Sewer Overflow) to the land or surface waters and the SSO constituted making an
outlet to waters of the State for purposes of G.S. 143-215.1(a)(1), for which a permit is required by G.S.
143-215.1.
The Raleigh Regional Office is providing the Town of Cary an opportunity to provide evidence and justification as
to why the Town of Cary should not be assessed a civil penalty for the violation(s) that are summarized below:

This Notice of Violation / Notice of Intent to Enforce (NOV/NOI) is being issued for the noted violation. Pursuant
to G.S. 143-215.6A, a civil penalty of not more than twenty-five thousand dollars ($25,000.00) may be assessed
against any person who violates or fails to act in accordance with the terms, conditions, or requirements of any
permit issued pursuant to G.S. 143-215.1.
This office requests that you respond to this Notice, in writing, within 10 business days of its
receipt. In your response, you should address the causes of non-compliance, remedial actions, and all other
actions taken to prevent the recurrence of similar situations. The response to this correspondence will be
considered in this process. Enforcement decisions will also be based on volume spilled, volume reaching surface
waters, duration and gravity, impacts to public health, fish kills or recreational area closures. Other factors
considered in determining the amount of the civil penalty are the violator's history of non-compliance, the cost of
rectifying the damage, whether the spill was intentional and whether money was saved by non-compliance.

Cary takes pride in the operation and management of our nearly 1,000 miles of
wastewater collection system. We are an award winning and progressive wastewater
utility that has very few reportable or large volume SSO. We place emphasis on
responding quickly to sewer emergencies to prevent and minimize any spills that impact
our citizens, community, and environment. We appreciate the opportunity to provide
information on the recent sewer overflows, our efforts, and justification for why additional
enforcement action or civil penalty should not be assessed to the Town of Cary.

SSO Notice of Violation - Notice of Intent August 4, 2022
INCIDENT # 202200880 — 4100 Cary Oaks Drive
Sewer Overflow Cause - On June 9, 2022 town staff received a phone call at 5:26 PM
from a citizen that lives adjacent to 4100 Cary Oaks Drive in Apex, reporting water flowing
from a manhole. Cary wastewater collection system staff immediately responded to
investigate the call. Staff observed two overflowing manholes (SP76011033 and
SP76011035) that were adjacent to each other. Sewer was exiting one manhole at a
height of 3.5 inches from four one-inch vent holes and the other manhole three quarters
of an inch through one one-inch vent. Wastewater flowed from the manhole into Camp
Branch. The Sewer Spill Estimation Guide provided on the NCDEQ website along with
site conditions was used to estimate the total sewer spilled reaching the stream. Cary
staff used a hydraulic sewer jetting machine to clear the blockage and stop the sewer
overflow at 8:01 PM.
The cause of the spill was associated with a 10-inch sewer line cleaning that was
preformed on June 8, 2022 in preparation for a planned sewer line maintenance and
repair project. The sewer line was being proactively cleaned for a planned pump station
force main pigging/cleaning operation and the replacement of an air release valve and
manhole. The cleaning activity removed debris from the 10-inch gravity sewer line where
debris strainers and vacuum trucks were used to collect the debris. During the cleaning
operation some gravel and sediment debris traveled downstream to an adjoining sewer
line and manhole which resulted in an obstruction that lead to the backup and SSO.
Sewer Spill Cleanup — After stopping the sewer spill, Cary staff immediately began
cleaning up the spill. A temporary dam was constructed downstream in Camp Branch
beyond where the sewer spill traveled. Pumps were set up and the stream was flushed
with 66,500 gallons of dechlorinated potable water. The wastewater and flushing waters
were pumped into the sanitary sewer system for treatment. Cleaning and flushing
occurred for approximately 12 hours.
Sewer Spill Assessment - The Town performed conductivity readings following the
overflow and during the spill cleanup to assess the spill and cleanup efforts. The following

Corrective Actions — On June 10, the NCDEQ Raleigh Regional Office was notified and
a news release was published and distributed within 24 hours following the sewer spill
(Enclosed). After clearing the blockage, the area sewer lines were hydraulicly cleaned
and video inspected (1,411 feet cleaned and 633 feet video inspected) to ensure there
was no additional accumulation or partial sewer line blockages. The video assessment
identified some tuberculation (Photo 1.) on the interior of the 10-inch gravity sewer ductile
iron pipe which contributed to the volume of debris removed with prior cleaning. We are
adding this sewer line segment to our
programming for rehabilitation and cure-in-

Enforcement Actions —We request NCDEQ to consider that this unfortunate sewer spill
was unintentionally caused by measures that were under way for planning for a proactive
force main cleaning and repair project. We are disappointed that this spill occurred and
that it was caused by our cleaning efforts. As Cary's collection system operation and
maintenance program emphasizes the use of predictive and preventative measures to
keep our system operating properly, this cleaning event supports an important force main
cleaning and repair project which if not addressed could lead to a larger magnitude event.
INCIDENT # 202200983 — 8921 Holly Springs Road
Sewer Overflow Cause - On June 22, 2022 town staff received a phone call at 11:30 AM
from a citizen reporting water flowing from a manhole located at 8921 Holly Springs Road,
Apex. Cary wastewater collection system staff immediately responded to investigate the
call. Staff observed an overflowing manhole (SP76011061). Sewer was exiting 2 vent
holes at a height of a quarter of an inch and flowed into a depression in the ground that
ponded in an area 45' X 20' with an average depth of 4-inches. Wastewater flowed from
the ponded area into an unnamed tributary to Camp Branch. The Sewer Spill Estimation
Guide provided on the NCDEQ website along with site conditions was used to estimate
the total sewer spilled that ponded and reached the stream. Sewer volume estimates
were based on a larger estimated total volume due to site conditions, spill ponding, and

SSO Notice of Violation — Notice of Intent August 4, 2022
a citizen report that was received regarding a leak on
June 21, but no sewer spill was found. Cary staff used . , , � t
a hydraulic sewer jetting machine to clear the
blockage and stop the sewer overflow at 1:02 PM. The 1
cause of the spill was a piece of broken concrete
(Photo 2.) from past construction activities that ''
allowed debris to collect in the 8-inch sewer line
leading to a blockage.
Sewer Spill Cleanup After stopping the sewers ill
Cary staff immediately began cleaning up the spill. A t`t� ,
temporary dam was constructed downstream in the r _
tributary beyondspillPumps the sewer site. Pum s were set Photo 2. -Concrete removed from sewer line
up and the creek was flushed with 17,200 gallons of
potable water. The wastewater and flushing waters were pumped into the sanitary sewer
system for treatment. Cleaning and flushing occurred for approximately 1.5 hours.
Sewer Spill Assessment - The Town performed conductivity readings following the
overflow and during the spill cleanup to assess the spill and cleanup efforts. The following
table provides a summary of the data collected at the time of the SSO and with sewer
spill cleanup. Eighty-eight minnows were affected and collected from the spill cleanup.
The use of potable water, hot weather conditions around 100 degrees, and increased flow
in the tributary is believed to have negatively affected the fish.

video inspected to ensure there were no additional accumulations or sewer line
blockages. The video assessment did not identify any additional issues with the 8-inch
sewer line. Removal of the broken concrete remedied the cause for the blockage, and we
no longer expect there to be any operational issues. Cary's history of inspection included
a manhole and easement inspection December 1 , 2021.

SSO Notice of Violation- Notice of Intent August 4, 2022
We appreciate the opportunity in being able to provide information on both unfortunate
sewer spills. These two instances are the only sewer spills that have occurred in those
separate sewer line segment areas. We appreciate NCDEQ's consideration in evaluating
these sewer spills, the cause, and Cary's record and response to remediate and help
ensure that a SSO does not reoccur at these locations. If we can answer any questions
or provide any additional information, please feel free to contact Mr. Donald Smith,
