Pursuant to G.S. 143-215.6A(c), in determining the amount of the penalty I have taken into account the Findings of Fact and
Conclusions of Law and the factors set forth at G.S. 143B-282. I (b), which are:
(1) The degree and extent of harm to the natural resources of the State, to the public health, or to private property
resulting from the violation;
(2) The duration and gravity of the violation;
(3) The effect on ground or surface water quantity or quality or on air quality;
(4) The cost of rectifying the damage;
(5) The amount of money saved by noncompliance;
(6) Whether the violation was committed willfully or intentionally;
(7) The prior record of the violator in complying or failing to comply with programs over which the Environmental

Within thirty (30) days of receipt of this notice, you must do one of the following:
(1) Submit payment of the penalty, OR
(2) Submit a written request for remission, OR
(3) Submit a written request for an administrative hearing
Option 1: Submit payment of the penalty:
Payment should be made directly to the order of the Department of Environmental Quality (do not include waiver
form). Payment of the penalty will not foreclose further enforcement action for any continuing or new violation(s).
Please submit payment to the attention of:
Attn: PERCS Branch
Division of Water Resources
1617 Mail Service Center
Raleigh, North Carolina 27699-1617

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 detennining 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 thirty (3 ) days of receipt of this
notice. The Division of Water Resources also requests that you complete and submit the enclosed "Justification for

Sanitary Sewer Overflows - December 2023
Collection System Permit No. WQCS00002
Raleigh Collection System
Wake County
Dear Mr. Wheeler:
A review has been conducted of the self -reported Sanitary Sewer Overflows (SSO's) 5-Day Report/s submitted by
City of Raleigh. The Division's Raleigh Regional Office concludes that the City of Raleigh violated Permit Condition I
(2) of Permit No. WQCS00002 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 City of Raleigh an opportunity to provide evidence and justification as
to why the City of Raleigh 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.
If you have any questions, please do not hesitate to contact Kevin Fowler with the Water Quality Section in the
Raleigh Regional Office at 919-791-4200 or via email at [e-mail].

Re: Response to NOV-2024-DV-0014
Sanitary Sewer Overflows -- December 2023
Permit No. WQCS00002
Dear Mrs. Manuel:
FEB - 2 20A
Please allow this letter to respond to the Notice of Violation document (NOV-2024-DV-0014) dated January
09th, 2024, and received by Raleigh Water on January 17th, 2024. This document contains the narrative
regarding the pending five Notice of Violation actions of Sanitary Sewer Overflows (SSO) incidents reported in
the month of December 2023 within the City of Raleigh Collections System III- This document also provides
exhibits as proof of our efforts to mitigate the sewer incidents. The noticed incidents occurred while the City
operated its collection system, according to WQCS00002, dated June 06th, 2017. The permit includes the
language outlined in footnote one and applies to the SSOs upon which NOVs with the notice of intent (NOV-NOI)
were based. This document will establish a reasonable explanation of the actions taken to stop the spills, contain
the released untreated wastewater, collect the wastewater and reintroduce it to the collection system; and
finally, restore the possible environmental impacts brought by the release of the SSO incidents, listed with the
intended NOV-NOI action. Please find below the additional information requested for the SSO incidents.
1. "The Director may take enforcement action against the Permittee for SSOs that must be reported to the Division as
stipulated in Condition IV92). This includes 5SOs that were caused by severe natural conditions or exceptional events
unless the Permittee demonstrates through properly signed, contemporaneous operating logs or other relevant
evidence that:
[a.I The SSO was caused by severe natural conditions; there were no feasible alternatives to the SSO, such as the use of auxiliary treatment facilities, retention of
untreated wastewater, reduction of inflow and infiltration, use of adequate backup equipment, or an increase in the capacity of the system. This provision is not
satisfied if, in the exercise of reasonable engineering judgment, the Permittee should have installed auxiliary or additional collections system components, wastewater
retention or treatment facilities, adequate backup equipment, or should have reduced inflow and infiltration or
[b.] The SSO was exceptional, unintentional, temporary, and caused by factors beyond the reasonable control of the Permittee; the SSO could not have been prevented
by the exercise of reasonable control, such as proper management, operation, and maintenance; adequate treatment or collection facilities or components (e.g.,
adequately enlarging treatment of collection facilities to accommodate growth or adequately controlling and preventing infiltration and inflow); preventative
maintenance; or installation of adequate backup equipment;"

Incident Number # 20230160012/02/2023 — 3731 Charleston Park DR., Raleigh, NC, 27604
This spill was neither willful nor intentional. It resulted from a grease build-up, restricting the sewer flow within
a section of the 8-inch gravity sewer main. This build-up led to a sewer spill of approximately 4,680 gallons of
untreated wastewater, approximately 2,680 gallons of which reached an unnamed tributary within the Neuse
Basin. (See Exhibit 1—Area of Operation)
On 12/02/2023, at approximately 10:55 PM, Raleigh Water staff responded to a customer complaint about a
sewer odor near 3731 Charleston Park, DR., Raleigh. Upon arrival, Utility Responders identified an active sanitary
sewer overflow emanating from a sanitary sewer manhole (see exhibit 2- Affected Asset-SMH11214$). The
responding staff took all reasonable steps to stop and mitigate the impact of the discharge, gaining control of
the spill incident by 12:13 AM on 12/4/2023. Crews utilized hydraulic jetting to remove the source of the
blockage within the affecting asset, thus restoring sewer flow.
Exhibit 2 — Affected Asset

Containment and collection of this spill incident consisted of employing a temporary containment site
downstream of the affected asset. This approach was intended to contain wastewater flow and minimize the
environmental impact on the surrounding land. Crews successfully contained approximately 2,000 gallons of
untreated wastewater before it reached the state's surface waters, preventing further environmental pollution
(see Exhibit 3 — Containment and Collection efforts). Responding crews employed pumps at the temporary
containment site to recover flushed wastewater and any evidence of sewer completing the operation by re-
introducing the contained wastewater to the collection system. This spill was contained without a significant
environmental impact on the adjacent area and its natural resources. Visual inspection of the affected area and
downstream waters confirmed no fish kill or unnecessary vegetative damage.
Exhibit 3- Containment and Collection Efforts
During the restoration phase of the operation, crews utilized ample potable water to flush the affected area and
remove sewer traces from the surrounding area. The area around the manhole and containment area was
cleared of debris, treated with lime, and restored with grass seed and straw.
Exhibit 4 —Restoration Efforts

Further assessment of this incident determined that grease accumulation on the gravity main that feeds into 24-
Peyton Wall PS caused a grease blockage that led to the subsequent overflow. Code enforcement action was
initiated to send educational outreach material to approximately 358 property owners upstream of the affected
area. The requested outreach literature explains the need for customers to use the sanitary sewer collection
system properly. It also serves as an opportunity for citizens to partner with Public Utilities to protect the City's
water quality and the sewer collection infrastructure. See Exhibit 5 — Code Enforcement Educational Outreach
Effort.

The cost associated with the mitigation of this incident amounted to $1,809.50. The approximate cost to the
Utility to treat 4,680 gallons of wastewater would have been approximately $7.02. The City saved no money
from this spill. Its costs for cleanup exceeded the cost of treating the volume of sewage had no spill occurred.
Furthermore, the City still had to pay for treating the greater volume of sewage created by the spill.
This section of the collection system is located downstream of a residential area. It provides sewer collection
services to approximately 358 properties upstream of the spill incident (see Exhibit 6 - Zone of Influence). This
specific portion of the collection system experienced a non -reportable grease -related 5SO incident on 2/11/2022
in which approximately 135 gallons of untreated wastewater remained on the ground and did not reach surface
waters. The affected asset has been identified as a hot spot for recurrent maintenance at 90 to 120 days.

No additional issues have been associated with this section of the collection system since the last sewer
incident. This site continues to remain an active maintenance spot pending the completion of further sewer
main cleaning and CCTV assessment.

Incident Number # 20230161012/06/2023 — 908 Cherry Pond Ct., Wake Forest, NC
This spill was neither willful nor intentional. It resulted from a grease build-up, restricting the sewer flow within
a section of the 8-inch Polyvinyl Chloride gravity sewer main. This build-up led to a sewer spill of approximately
2,530 gallons of untreated wastewater remaining within the natural topography and not reaching surface
waters. See Exhibit 1— Area of Operation.
On 12/06/2023, at approximately 6:22 PM, Raleigh Water staff responded to a sewer overflow customer
complaint near 908 Cherry Pond Ct., Wake Forest, NC. Upon arrival, Utility Responders identified an active
sanitary sewer overflow emanating from a private sanitary sewer cleanout (see exhibit 2- Affected Asset), which
resulted from a grease blockage of the downstream sewer main. The responding staff took all reasonable steps
to stop and mitigate the impact of the discharge, gaining control of the spill incident by 7:05 PM on 12/6/2023.
Crews utilized hydraulic jetting to remove the source of the blockage within the affecting asset, thus restoring
sewer flow.
EMh[blt 2 — Affected Asset
Containment and collection of this spill incident consisted of removing the untreated wastewater from the
natural depression utilizing excavators and dump trucks to haul away any surface soil affected by sewer debris
accumulation. This approach was intended to contain wastewater flow and minimize the environmental impact
7

on the surrounding land. Crews successfully contained, collected, and removed approximately 46 cubic yards
(77,840 lbs.) of untreated wastewater -saturated soil before it reached the surface waters of the state,
preventing further environmental pollution (see Exhibit 3 — Containment, Collection and Removal Efforts). This
spill was contained without a significant environmental impact on the adjacent area and its natural resources.
Exhibit 3- containment, Collection, and Removal Efforts
During the restoration phase of the operation, crews remove all traces of untreated wastewater debris from the
surrounding area. The areas around the manhole and natural containment were cleared of debris, treated with
lime, and restored with grass seed and straw. See Exhibit 4 — Restoration Efforts
8

Exhibit 4 — Restoration Efforts
Further CCTV assessment of this incident is scheduled to determine the source of the grease accumulation that
led to the subsequent overflow. A code enforcement action was initiated to send educational outreach material
to approximately 195 property owners upstream of the affected area. The requested outreach literature
explains the need for customers to use the sanitary sewer collection system properly. it also serves as an
opportunity for citizens to partner with Public Utilities to protect the City's water quality and the sewer
collection infrastructure. See Exhibit 5 — Code Enforcement Educational Outreach Effort.

Incident Number # 202301625—12/1212023 — 5832 Whitebud Dr., Raleigh
This spill was neither willful nor intentional; it resulted from debris accumulation (flushed wipes) blocking a
portion of an 8-in gravity sewer main. The debris accumulation led to a sewer spill of approximately 2,040
gallons of untreated wastewater, which remained on the natural topography and did not reach surface waters.
See Exhibit 1— Area of Operation.
Exh bit 1 —Area of Operation
On 12/11/2023, at approximately 1:31 PM, Raleigh Water staff responded to a sanitary sewer overflow
emanating from a sanitary sewer manhole (affected sewer asset SMH101678) located near 5832 Whitebud Dr.,
Raleigh, NC. The responding staff took all reasonable steps to stop and mitigate the impact of the discharge,
gaining control of the spill incident by 2:23 PM on the same day. Crews utilized hydraulic jetting to remove the
source of the blockage within the affecting asset, thus restoring sewer flow.
Containment and collection of this spill incident consisted of employing a temporary spill containment site
downstream of the affected area, restricting sewer flow to downstream surface waters. This approach was
intended to contain wastewater flow and minimize the environmental impact on the surrounding land.
Responding crews employed pumps at the temporary containment site to recover flushed wastewater and any
evidence of sewer completing the operation by reintroducing the wastewater to the collection system. This spill
was contained without a significant environmental impact on the adjacent area and its natural resources. Visual
inspection of the affected area and downstream waters confirmed no fish kill or unnecessary vegetative
damage.
During the restoration phase of the operation, crews utilized ample potable water to flush the affected area and
remove sewer traces from the surrounding area and downstream conveyance. The area around the manhole
was cleared of debris, treated with lime, and restored with grass seed and straw.
A CCTV assessment completed on 12/18/2023 after hydraulic jetting was completed identified some grease
accumulation but no infrastructure deficiencies that could have influenced grease to accumulate, creating a
blockage (see Exhibit 2 — Affecting Assets with Grease Accumulation).
12

A code enforcement action was initiated to send educational outreach material to approximately 112 property
owners upstream of the affected area. The requested outreach literature explains the need for customers to use
the sanitary sewer collection system properly. It also serves as an opportunity for citizens to partner with Public
Utilities to protect the City's water quality and the sewer collection infrastructure. See Exhibit 3 — Code
Enforcement Educational Outreach Effort.

The cost associated with the mitigation of this incident amounted to $4,531.93. The approximate cost to the
Utility to treat 2,040 gallons of wastewater would have been approximately $3.06. Raleigh Water saved no
money from this spill. Its costs for cleanup exceeded the cost of treating the volume of sewage had no spill
occurred. Furthermore, Raleigh Water still had to pay to treat the greater volume of sewage created by the spill.

Incident Number # 202301640—12/13/2023 — 8417 Sawyer Drive, Raleigh
This spill was neither willful nor intentional; it resulted from root intrusion, which blocked a portion of an 8-in
Vitrified -Clay Pipe gravity sewer main. The root intrusion led to a sewer spill of approximately 1,335 gallons of
untreated wastewater reaching an unnamed tributary within the Hare Snipe Basin (see exhibit 1— Area of
Operation)
On 1/13/2023, at approximately 5:08 PM, Raleigh Water staff responded to a sanitary sewer overflow
emanating from a sanitary sewer manhole (affected sewer asset SMH139284, see Exhibit 2 — Affected Asset)
located near 8417 Sawyer Drive, Raleigh, NC. The responding staff took all reasonable steps to stop and mitigate
the impact of the discharge, gaining control of the spill incident by 05:49 PM on the same day. Crews utilized
hydraulic jetting to remove the source of the blockage within the affecting asset, thus restoring sewer flow.
16

Containment and collection of this spill incident consisted of employing a temporary spill containment site
downstream of the affected area, restricting sewer flow to downstream surface waters. This approach was
intended to contain wastewater flow and minimize the environmental impact on the surrounding land.
Responding crews employed pumps at the temporary containment site to recover flushed wastewater and any
evidence of sewer completing the operation by reintroducing the wastewater to the collection system. This spill
was contained without a significant environmental impact on the adjacent area and its natural resources. Visual
inspection of the affected area and downstream waters confirmed no fish kill or unnecessary vegetative
damage. See Exhibit 3 —Containment and Collection Efforts.
During the restoration phase of the operation, crews utilized ample potable water to flush the affected area and
remove sewer traces from the surrounding area and downstream conveyance. The area around the manhole
was cleared of debris, treated with lime, and restored with grass seed and straw. See Exhibit 4 — Restoration
Efforts.

17

The cost associated with the mitigation of this incident amounted to $5,460.59. The approximate cost to the
Utility to treat 1,335 gallons of wastewater would have been approximately $2.00. Raleigh Water saved no
money from this spill. Its costs for cleanup exceeded the cost of treating the volume of sewage had no spill
occurred. Furthermore, Raleigh Water still had to pay to treat the greater volume of sewage created by the spill.
This section of the collection system is located downstream of a residential area. It provides sewer collection
services to several residences surrounding the spill incident. Within the last ten years, this specific portion of the
collection system has not experienced a root intrusion SSO. Sanitary sewer assets in this area have been
routinely maintained with subsequent chemical root control treatment.

Summary
The Sewer Maintenance Division of Raleigh Water strives to develop initiatives that improve operational
reliability to meet customer expectations and meet or exceed the Water Quality Collection System permit
requirements. Our operations are focused on continual improvement, the prevention of pollution, and increased
environmental performance efficiency. This endeavor is noted as the Division operates an ISO Certified
Environmental Management System governed by the 14001-2015 Standards. As part of these initiatives, the
Division operates a comprehensive reactive and preventive maintenance program to maintain over 2,644 miles
of sanitary sewer pipe and minimize the accidental release of untreated wastewater.
Since July 2023 (Fiscal Year 2024), the Utility has maintained approximately 803.9 [1- miles of gravity sewer mains
by flushing with hydraulic jetting, conducting CCTV assessments, and performing repair operations, easement
maintenance, and inspections. The fiscal year-to-date cost of these operations amounts to $1,339,456.68 1t1,
approximately 1% of the Division's annual operating budget. The 11,685 gallons of untreated wastewater,
identified as notice of violations in this letter, cost the Utility approximately $38,654.22 to mitigate. The City's
cost of sewer treatment per gallon is $.0015 t�[]. At this rate, treating the untreated wastewater spilled would
cost the City $17.52. The City saved no money from these spills. The costs of mitigation well exceeded the cost
of treating the volume of sewage had no spill occurred.
Furthermore, the City still had to pay for treating the greater sewage volume created by these spills. This fiscal
comparison shows the City's commitment to environmental protection, sparing no cost regardless of the spill
incident's severity and complexity. The City continues to demonstrate due diligence in environmental
performance by allocating resources to a spill incident regardless of the associated cost. This effort is noted in
the City's SSO performance rate of 1.27 total SSO rate 14: per 100 miles of pipe, compared to the Southeastern
Region of the U.S., of 7.0 spills per 100 miles of line.

Note
In FY-2023, the Raleigh Water -Sewer Maintenance Division spent $2,054,254.45 in operations to maintain, repair, and Inspect approximately 939.95 miles of
sanitary sewer Infrastructure.
Additionally, the City of Raleigh Assistant Public Utility Directors and Collections System staff have become
involved in challenging the nonwoven fabrics industry standards to better inform consumers of these products
and their detrimental effects on the collections systems. PUD staff has personally met with officers of INDA, the
leading association of the nonwoven fabrics industry based in Cary, NC, to communicate our concerns about
these fabrics, the current industry standards, and better education for the consumer, PUD has also joined forces
with other utilities nationwide through the National Association of Clean Waters Agencies (NACWA), the Water
22

Efi►rironment Foundation (WEF), and the American Public Works Association (APWA) to challenge INDA and
current industry standards, recognizing that they do not support compatibility in sanitary sewer collections
systems nationally. These agencies work collectively to challenge the testing protocols, assessment guidelines,
and consumer education and labeling of these non -dispersible.
Raleigh Water has an aggressive educational outreach initiative to address illicit discharges to commercial and
residential users, such as wipes, fats, oil, and grease. Raleigh Water has developed a complimentary property
managers resource kit that provides best practice resources for establishing a property -specific awareness
program. Each kit contains brochures and complimentary gadgets to help residents manage grease and fat
collection and disposal. The resource kit also features a multimedia flash drive with videos and reproducible
educational material that property managers can use to educate tenants to reduce the risk of sewer backups
caused by the introduction of solids through their residential piping. Each kit costs Raleigh Water approximately
$85.00 to produce and is provided free of charge to the property management. Raleigh Water continuously
develops initiatives to increase residential and commercial customer partnerships to address grease
accumulation and prevent illicit incident discharges. The educational material and videos can be accessed
through social media and the Raleigh Water website: https://raleighnc.pzov/sewer-maintenance
The City continues its monetary reward or bounty program, which pays out fifty ($50) to any citizen who
observes and reports an SSO or conditions that may cause a spill incident. This program has been advertised via
printed material, a television advertisement campaign, and graphic design "wraps" on Sewer Maintenance
vehicles. These graphics on our vehicles function as mobile billboards, spreading our prevention message and
offering contact information throughout the service area daily. This program was developed hoping that citizens
and customers would become more aware of the signs of an emerging system problem causing the SSO
occurrence and become proactive in helping the City prevent these occurrences. Additionally, all customers are
notified via their water and sewer utility bills not to discharge materials that could block the flow of the sanitary
sewer mains. The City also circulates information regarding grease discharge into the sewer system and the
effects of such deposits. Whenever possible, and upon investigating the root cause of a spill incident, PUD Code
Enforcement officers develop and send registered informational letters about the spill incident to the customer
base serviced by the line where the SSO has occurred. This educational outreach is done to educate our
customers on the proper use of sanitary sewers to prevent the disposal of non-flushable items and items
harmful to the continuous operation of the collections system.
On behalf of the City of Raleigh, I am requesting that the NOV-2024-DV-0014 issued for the month of December
2023 be fairly reviewed, considering the steps the Department has taken to protect the environment and meet
or exceed the requirements of the Collections System Permit. If additional information is required, don't
hesitate to contact Matthew Vessie, Sewer Maintenance Superintendent, at [phone] or Carlos M. Perez,
Assistance Superintendent, at 919-996-5929.

How was the SSO remediated (i.e. Stopped and cleaned up)?
Crews were dispatched out due to an odor call in the area. Once on site crews were able to identify SMH112198
surcharging and immediately began attempts to break the blockage. The affecting asset was identified as SGMN166507
within the pate of PS 24 Peyton Hall. Once crew were able to gain access to the pump station the blockage was removed
using hydraulic flush truck, Containment and restoration process has begun."
Sewer maintenance crews were dispatched last night 12/2/2023 for a sewer odor (a)3731 Charleston Park Dr. Crews arri\
on -site and began preliminary investigations. Crews were able „to identify at least 6 MH. s that were holding. Flushing cr&
were able to locate and witness SMH112198 surcharging (a)rate of 60gpm. Sewer maintenance flushing crews utilized
hydraulic letting to remove the source of the blockage with in SGMN166507 thus restoring sewer flow. The blockage was
removed and -flow restored in the sewer gravi1y main C@ 12:13am on 121312023. Sewer maintenance reactive crews are
currently on site beginning the restoration process. Crews were able to cease the SSO with 78 minutes. Untreated
wastewater water did indeed reach the storm drain channel and ultimately reached an unnamed tributary to Neuse river
basin. Containment and collection of this spill event consisted of employing a temporary spill containment site downstrear
of the affected area at 3730 Charleston Park Dr. utilizing a 4 gasoline pump to remove any untreated waste water and
re -introduce the wastewater back into the collection system. This approach is intended to contain wastewater flow and
minimize the environmental impact of the surrounding area. The root cause was determined to be grease. Hydrants were
started to assist restoration of the open storm drain channel and notification has been sent to water distribution via email.
This spill was contained without significant environmental impact on the adjacent area and its natural resources. Visual
inspection of the affected area and downstream water confirmed no fish kill or unnecessary vegetative damage. The
estimated volume of gallons was determined to be 4680 gallons with 2000 gallons remaining on the natural topography. 3
areas around the manhole were cleared of debris , washed with potable water, treated with an application of lime , and
finally restored with grass seed and straw.

t. PERFORMANCE STAN©A �
1. The sewage and wastewater collected by this system shall be treated in the properly permitted
Wastewater Treatment Facility identified in the permit application and documented in the Division's
database. 115A NCAC 02T .0108 (b))
2. The Director may take enforcement action against the Permittee for SSOs that must be reported to the
Division as stipulated in Condition IV (2). This Includes SSOs that were caused by severe natural
conditions or exceptional events unless the Permittee demonstrates through properly signed,
contemporaneous operating logs, or other relevant evidence that:
a. The SSO was caused by severe natural conditions; there were no feasible alternatives to
the SSO, such as the use of auxiliary treatment facilities, retention of untreated wastewater,
reduction of inflow and infiltration, use of adequate back-up equipment, or an increase in
the capacity of the system. This provision is not satisfied if, in the exercise of reasonable
engineering judgment, the Permittee should have installed auxiliary or additional collection
system components, wastewater retention or treatment facilities, adequate back-up
equipment or should have reduced inflow and infiltration; or
b. The SSO was exceptional, unintentional, temporary and caused by factors beyond the
reasonable control of the Permittee; the SSO could not have been prevented by the
exercise of reasonable control, such as proper management, operation and maintenance;
adequate treatment facilities orcollection system facilities or components (e.g., adequately
enlarging treatment or collection facilities to accommodate growth or adequately
controlling and preventing infiltration and inflow); preventive maintenance; or installation
of adequate back-up equipment;
The Permittee can submit a claim to the Division Regional Office that the SSO meets the criteria of
this condition. The Permittee has the option of submitting this claim along with the spill report
required by Condition IV(2) (i.e., within five business days) in order to be considered for Immunity
from enforcement action. Form CS-SSO Part II, or most current Division approved form, shall be
used for any claims. The Permittee has the burden of proof that the above criteria have been met.

4. The Permittee shall develop and implement an educational fats, oils and grease program that shall
include at least semiannual distribution of educational material targeted at both residential and non-
residential users. The Permittee shall also develop and implement an enforceable fats, oils and grease
program for non-residential users under which the Permittee can take enforcement against users who
have not properly installed, operated and maintained grease traps or grease Interceptors as directed
or otherwise violated the terms of the enforcement program pertaining to fats, oils and grease.
(15A NCAC 02T .0108 (b)]
S. The Permittee shall adopt and implement a Capital Improvement Plan (CIP) to designate funding for
reinvestment into the wastewater collection system infrastructure. The CIP should address the short-
term needs and long-term "master plan" concepts. The CIP should typically cover a three to five year
period and include a goal statement, description of the project area, description of the existing facilities,
known deficiencies (over a reasonable period) and forecasted future needs. Cost analysis is integral to
the CIP. [G.S.143-215.9B]
