(I)
(2)
(3)
Submit payment of the penalty, OR
Submit a written request for remission, OR
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 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 143B-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 (30) days of receipt of this
notice. The Division of Water Resources also requests that you complete and submit the enclosed "Justification for

Please allow this letter to serve as a response to the Notice of Violation & Intent to Issue Civil Penalty
document (NOV-2022-DV-0199) received on July 22nd, 2022. This document contains the narrative regarding
pending violation actions of (3) Sanitary Sewer Overflow (SSO) events, reported on the month of June 2022
within the City of Raleigh Collections System [1]. This document also provides exhibits as proof of our efforts to
mitigate each of the sewer events. The noticed events occurred while the City operated its collection system,
according to WQCS00002, dated June 6th, 2017. The permit includes the language outlined in footnote 1 and
applies to the SSOs upon which NOVs with the notice of Intent (NOV-N01) 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 events, listed with the intended NOV-NOI action.
Please find below, the additional information requested for the SSO events.
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 SSOs that was 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 ahernatives to the 550, such as the use of auxiliary treatment fadllties, 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 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 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 back-up equipment;"

Incident Number # 2022000292 - 06/25/2022 -12408 Village Pines Ln, Raleigh NC
This spill was neither willful nor intentional. It resulted from a grease build-up, restricting the sewer flow
within a section of a 12-inch ductile iron pipe gravity sewer main. This build-up led to a sewer spill of
approximately 34,800 gallons of untreated wastewater in which roughly 31,400 gallons remained within the
natural topography and/or were absorbed by the surrounding soil. A further site assessment estimated that
roughly 3,400 gallons may have reached an unnamed tributary that discharges into surface waters of the Neuse
River (see exhibit 1— Area of Operation). However, visual observation did not identify wastewater debris near
the tributary's discharge into the Neuse River.
Note
The NOV/NOI letter erroneously shows that 31,400 gallons reached surface water Instead of 3,400.
The Raleigh Regional Office is providing the Oty of Raleigh an opportunity to provide evidence and justification as
to wily the City of Raleigh shoukf not be asseaaed a civil penalty for the vlolatlon(s) that are summarized below:

Exhibit 1—Area of gyration
On 06/25/2022, at approximately 8:49 AM, Raleigh Water staff responded to a sanitary sewer overflow
emanating from a sanitary sewer manhole (affected assets SMH123111) located near 12408 Village Pines Ln,
Raleigh NC. The responding staff took all reasonable steps to stop and mitigate the impact of the discharge,
gaining control of the spill event by 11:43 AM on the same day. Crews utilized hydraulic jetting to remove the
source of the blockage within the affecting asset2, thus restoring sewer flow.
The natural topography of the surrounding land, southwest of the affected asset, served to partially contain
approximately 31,400 gallons of untreated wastewater. The ground surrounding the affected manhole absorbed
a vast portion of untreated water before it reached surface waters of the Neuse River. See Exhibit 2 — Natural
containment. This spill was naturally and partially 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.
!Affected Asset Structure within the collection system that allowed the release of untreated wastewater Into the environment, typically a sewer manhole.
2. Affecting Asset Structure within the collection system that housed a blockage that resulted In an SSO, typically a sewer gravity main.

During the restoration phase of the operation, crews mechanically removed sewer -contaminated soil and
utilized over 3,000 gallons of 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 an application of lime, and restored with grass seed and straw. See Exhibit 3 — Site Restoration.
Exhibit 3 — Site Restoration
The cost associated with the mitigation of this event amounted to $2,924.07. The approximate cost to the Utility
to have treated 34,800 gallons of wastewater would have been approximately $52.20. 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 the cost 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 over 200 residences upstream of the spill event (see Exhibit 4- Zone of Influence3). Within the last ten
years, this specific portion of the collection system has not experienced a grease -related SSO event. This area
has been placed on routine maintenance.
3. Zone of Influence: Area upstream from an 55o that contains homes or businesses whose discharge of wastewater may have contributed to the creation of a
system blockage. Identifying this area is critical to analyz.ng potent.al sources of illicit discharges such as grease or rags that generate blockages, as well as
determining where educational materials can be distributed post -Incident to educate residents regarding the proper use of the collection system.

Exhibit 4- Zone of influence
Outreach information literature was requested to be sent to the immediate -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.
A press release notification was requested to be published in the Raleigh News & Observer as required by NCGS
Article 21, Chapter 143.215.1C. See Exhibit 5 — Press release. Outreach information literature was requested to
be sent to the immediate -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

Incident Number # 202200994 — 6/26/2022 — 6600 Glenwood Ave., Raleigh NC
This spill was neither willful nor intentional. It resulted from a grease build-up, restricting the sewer flow
within a section of 8-inch polyvinyl chloride (PVC) pipe gravity sewer main. This build-up led to a sewer spill of
approximately 1,905 gallons of untreated wastewater remaining on the ground and not reaching the surface
waters of the state. (See Exhibit 1— Area of Operation)
Exhibit 1—Arai of Operation
On 6/26/22, at approximately 3:38 PM, Raleigh Water staff responded to a sanitary sewer overflow emanating
from a sanitary sewer manhole (SMH148641) located near 6600 Glenwood Ave., Raleigh NC. The responding
staff took all reasonable steps to stop and mitigate the impact of the discharge, gaining control of the spill event
by 5:45 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 event consisted of employing a vacuum truck to recover stagnant
wastewater that remained in the natural topography. 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 re -introducing 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. The area around the manhole and containment area was
cleared of debris, treated with an application of lime, and restored with grass seed and straw.
A follow-up CCTV assessment was conducted on 6/28/2022 to identify the root cause of the SSO. The CCTV
assessment identified the root cause to be a large offset joint within Sewer gravity main 105239 located 237.4'
downstream from Sewer manhole 120710. See Exhibit 2 — Offset joint. The assessment recommended a point
repair (Work Order #1448802) to remove the offset joint and conduct a follow-up camera inspection to view the
rest of the pipe. These assets have been placed on the Division's Hotspot list for increased maintenance.

The cost associated with the mitigation of this event amounted to $1,992.67. The approximate cost to the Utility
to have treated 1,905 gallons of wastewater would have been approximately $2.85. 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 the cost to treat the greater volume of sewage created by the spill.
This section of the collection system is located downstream of a commercial area. It provides sewer collection
services to several food service establishments (see Exhibit 4- Zone of Influence). A Fats, Oils, and Grease (FOG)
assessment conducted a compliance follow-up at fourteen (14) food service establishments upstream from the
affecting asset located in the Townridge Shopping Center. Two of these establishments are currently out of
business, yielding twelve (12) total inspections to be completed. This specific portion of the collection system
has not experienced a grease -related SSO event within the last ten years. This area will be placed under routine
maintenance upon completion of the point repair.

A press release notification was requested to be published in the Raleigh News & Observer as required by NCGS
Article 21, Chapter 143.215.1C. See Exhibit 5 — Press release. Outreach information literature was requested to
be sent to the immediate -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.

Incident Number # 202200996 — 6/27/2022 — 2214-2598 Garner Station Blvd., Raleigh, NC
This spill was neither willful nor intentional; it resulted from a large quantity of debris that entered the
wet well during the night of 6/26/2022. This accumulation affected the pump cycle and wastewater flow
capacity.
On the morning of 6/27/2022, a pump station mechanic arrived on site for a routine station check and found the
wet well overflowing. Immediate was taken to mitigate the scene. Upon initial assessment, it was determined
that although the debris accumulation allowed the pumps to cycle on as normal, once the wet well level began
to drop the debris became entangled in the alarm floats and affected the wet well MultiTrode level controller.
As the well began to fill again, the MultiTrode level controller was able to cycle the pumps ON but had reached
the point it wasn't able to cycle the pumps OFF. The alarm floats were found entangled and were unable to send
signals via SCADA. As the pumps continued to run, the debris was being sucked into each pump until pump #1
had an amperage overload and the resulting fault tripped the main breaker. Pump #2 continued to take in debris
until it had been damaged to the point it was unable to move water. Both pumps ultimately needed to be
replaced. Subsequently, bypass pumping was immediately established to control flow coming into the wet well.
This event resulted in the approximate loss of 12,300 gallons of which roughly 3,500 gallons remained within the
natural topography not reaching surface waters of the state. This event affected an unnamed tributary of the
Upper Swift Basin. See Exhibit 1- Area of Operation.

Containment and collection of this spill event consisted of placing a temporary containment dam downstream of
the station This emplacement contained filtering media to stop wastewater debris from flowing downstream. A
water pump was placed in the containment dam to collect and transfer the wastewater from the stream and
reintroduce it into the collection system. Vacuum trucks were used to remove wastewater from the pump
station returning the wastewater elsewhere into the collection system. See Exhibit 2 - Containment and
Collection Efforts.

Restoration of this spill event consisted of washing the land surrounding the station. Sewer debris and solids
were collected and disposed of accordingly. Crews utilized ample potable water to flush the affected area. 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 that no fish kill or unnecessary
vegetative damage occurred. See exhibit 3 — Restoration Efforts.

The cost associated with the mitigation of this event (including replacement of two pumps and labor) amounted
to over $80,490.30. The approximate cost to the Utility to have treated 12,300 gallons of wastewater would
have been approximately $18.45. 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 the cost to
treat the greater volume of sewage created by the spill.

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 significantly 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 preventative maintenance program whose goal is
to maintain over 2,566 miles of sanitary sewer pipe and minimize the accidental release of untreated
wastewater.
Since July 2022 (Fiscal Year 2023), the Utility has assessed approximately 26.24 [1J 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
$ 219,544.69 PI, approximately .016% of the Division's annual operating budget. The 49,005 gallons of untreated
wastewater spill identified in this letter cost the Utility approximately $85,407.04. to mitigate. The City's cost of
sewer treatment per gallon is $.0015 [3J. At this rate, it would have cost the City $73.50 to treat the entire
volume of sewer spilled. 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 the cost to
treat 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 event's severity and complexity. The City
continues to demonstrate due diligence in environmental performance by allocating the necessary resources to
a spill event irrespective of the associated cost. This effort is noted in the City's low SSO performance rate of
0.31 total SSO rate ]4] per 100 miles of pipe, compared to the Southeastern Region of the US, of 7.0 spills per 100
miles of line. In the previous Fiscal year 22 total performance miles assessed were 417.34 Miles at a cost of
$ 2,829,598.09.

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
Environment 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 such as wipes, fats,
oil, and grease to commercial and residential users. 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 is continuously
developing initiatives to increase residential and commercial customer partnerships to address grease
accumulation and prevent illicit discharges. The educational material and videos can be accessed through social
media and the Raleigh Water website httos://raleiRhnc.govbg_wer-maintenajice
The City continues its monetary reward program or bounty program, which pays out fifty ($50) dollars to any
citizen that observes and reports an SSO or conditions that may cause a spill event. 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 message of
prevention and offering contact information throughout the service area each day. 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 improper materials into the
sanitary sewer mains. The City also circulates information regarding the discharge of grease into the sewer
system and the effects of such deposits. Whenever possible, and upon investigating the root cause of a spill
event, PUD Code Enforcement officers develop and send registered informational letters about the spill event to
the customer base serviced by the line where the SSO has occurred. This 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-2022-N01-00199 issued for the month of June
2022 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, please
contact Matthew Vessie, Sewer Maintenance Superintendent [phone], or Carlos M. Perez, ORC

How was the SSO remediated (i.e. Stopped and cleaned up)?
Crews utilized hydraulic letting to remove the source of the blockage from the affecting asset thus restoring sewer flow. A
temporary spill containment site was emplaced downstream of the affected asset in order to contain the flow of sewer anc
minimize the environmental impact on the surrounding land. Crews utilized ample potable water to flush the area and
remove traces of sewer from the affected area. Flushed water was then collected at the temporary containment point and
reintroduced to the collection system. CCTV inspection and FOG assessment will follow.

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 dvil penalty for the violation(s) that are summarized below:

In accordance with your application received May 19, 2015 and Settlement Agreement (16 EHR 00538 and
16EHR 00843), we are forwarding herewith Permit No. WQCS00002, dated June 6, 2017, to the City of Raleigh
for the operation and maintenance of the subject wastewater collection system.
This permit shall be effective from June 6, 2017 until January 31, 2024 and shall be subject to the conditions
and limitations specified herein. It is your responsibility to thoroughly review this permit. Please pay particular
attention to the monitoring and reporting requirements in this permit and any special conditions.
For purposes of permitting, the collection system is considered to be any existing or newly Installed system
extension up to the wastewater treatment facility property or point of connection with a separately owned
sewer system. The collection system is considered all gravity lines, pump stations, force mains, low pressure
sewer systems, STEP systems, vacuum systems, etc. and associated piping, valves and appurtenances that
help to collect, manage and transport wastewater to a wastewater treatment plant under the Permittee's
ownership or maintained and operated by the Permittee through a perpetual legal agreement. Satellite
systems are systems tributary to the Permittee's collection system but those collection systems are not owned
or maintained by the Permittee. The system description provided on Page 1 of this permit is meant to provide
a general idea about the size of the system and may not be all inclusive of the collection system at the time of
permit issuance or afterward.
A discharge of wastewater to the environment from the Permittee's wastewater collection system prior to
reaching the wastewater treatment facilities is referred to herein as a Sanitary Sewer Overflow (SSO). The
evaluation of enforcement options after an SSO will be determined considering all relevant information
available or requested of the Permittee. Compliance with all conditions of the permit as well as all statutes
and regulations pertaining to the wastewater collection system must be maintained or appropriate
enforcement actions may be taken as noted in Condition VI(2).

CS-SSO can be downloaded from the SSO Reporting area at: httn://portal.ncdenr.ore/web/wo/swn/oslcs/sso
A notice of deficiency (NOD), notice of violation (NOV), civil penalty, and/or a moratorium on the addition of
waste to the system may be issued if adequate justification for an SSO Is NOT submitted to the regional office.

documentation as necessary. DWR staff will review the justification claim and determine if enforcement
action is appropriate. Please be advised that the information needed to justify a spill is very comprehensive.

request an adjudlcatory hearing upon written request within thirty days following the receipt of this permit.
This request must be in the form of a written petition, conforming to Chapter 1508 of the North Carolina
