Option 2: Submit a written request for remission or mitigation including a detailed justification for such
request:
Please be aware that a request for remission is limited to consideration of the five factors listed below as they may
relate to the reasonableness of the amount of the civil penalty assessed. Requesting remission is not the proper
procedure for contesting whether the violation(s) occurred or the accuracy of any of the factual statements contained in
the civil penalty assessment document. Because a remission request forecloses the option of an administrative hearing,
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:
(1) whether one or more of the civil penalty assessment factors in NCGS 14313-282,1(b) was wrongfully
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
(5) whether payment of the civil penalty will prevent payment for the remaining necessary remedial actions.
Please note that all evidence presented in support of your request for remission must be submitted in writing. The
Director of the Division of Water Resources will review your evidence and inform you of his decision in the matter of
your remission request. The response will provide details regarding the case status, directions for payment, and
provision for further appeal of the penalty to the Environmental Management Commission's Committee on Civil Penalty
Remissions (Committee). Please be advised that the Committee cannot consider information that was not part of the
original remission request considered by the Director. Therefore, it is very important that you prepare a complete and
thorough statement in support of your request for remission.
In order to request remission, you must complete and submit the enclosed "Request for Remission of Civil Penalties,
Waiver of Right to an Administrative Hearing, and Stipulation of Facts" form within thi!1y_(30) days of receipt of this
notice. The Division of Water Resources also requests that you complete and submit the enclosed "Justification for
Remission Request."

Construction Debris Causes Sewer Spill in Cary
On the morning of June 22: 2022, Cary responded to a 3,759-gallon sewer
spill near 8921 Holly Spr!ngs Road.
The spill Is the result of a piece of concrete construction debris lodged in the
sewer One.
A portion of the spill accumulated in a depression around the manhole that
spilled. The accumulated sewage was pumped back into the sewer system
for disposal and treatment. The spill was cleaned up and the area flushed
with water.
CARY, NC — A sewer spill in Cary occurred the morning of June 22, 2022
behind 8921 Holly Springs Road. Cary staff responded to the alert that came n
and 11:30 a.m. and stopped the spill at 1:02 p m The overall spill volume was
.,,59 gallons, which flowed into an unnamed tributary to Camp Branch.
The spill was caused by a piece of concrete construction debris that restricted
flow in the sewer tine resulting in a backup and manhole overflow. Approximately
1,600 of the 3,759 gallons accumulated in a depression around the manhole with
the remainder reaching the stream. The accumulation on the ground was pumped
back into the sewer system for disposal .and treatment and the ground was
cleaned by flushing with water. The sewer spill and cleanup activities affected
around 80 small fish.
As required by law, additional notification has been made to the State Department
of Environmental Quality, who YA1 review the incident. North Carolina General
Statutes require public notice !n the form of a news release issued by wastewater
ut#ity operators within 24 hours of the detection of a wastewater overflow of 1,000
gallons or greater that also reaches surface waters Paid advertisements are also
necessary for spiels of 15,000 gallons or greater

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-0 violation — Notice of Intent Agaust 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 (SP78011033 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
table provides a summary of the data collected at the time of the SSO and with sewer
spill cleanup. Four small catfish were affected and collected during the spill cleanup.

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 -
place pipe lining. i
Cary's history of inspection included
manhole inspections on December 1, 2021
with no issues identified at the time of the
inspection. The sewer line was last cleaned
the week of May 30, 2021. Following the
sewer spill the sewer lines in area were
cleaned and inspected to ensure we did not
have a repeated spill. The planned pump
station force main cleaning and repair
project is still scheduled to occur.

Enforcement Actions — We request NCDEQ to consider that this unfortunate sewer spill
was unintentionally caused by measures that were underway for planning for a proactive
fame 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 Viol on - Notice of 11ftent MAmust 4 2022
a citizen report that was received regarding a leak on
June 21, but no sewer spill was found. Cary staff used
a hydraulic sewer jetting machine to clear the
blockage and stop the sewer overflow at 1:02 PM. The
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 sewer spill, 1111111111111119ALMU IWAPIM,
Cary staff immediately began cleaning up the spill. A
temporary dam was constructed downstream in the -
tributary beyond the sewer spill site. Pumps were set Photo 2. - Concrete removedfrom 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.

no longer expect there to be any operational issues. Cary's history of inspection included
a manhole and easement inspection December 1, 2021.

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 violations) that are summarized below:
