Please allow this letter to serve as a response to the Notice of Violation & Intent to Issue Civil Penalty
document (NOV-2022-DV-0236) received on August 20"r, 2022. This document contains the narrative regarding
pending violation actions of (4) Sanitary Sewer Overflow (SSO) events, reported on the month of July 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-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 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.1 TheSSO was caused by severe natural condltlow, there were r+o fessbie alternatives to the SSO, such as the use of auxlYary treatment facilities, retention of
untreated wastewater, reduction of inflow and Infiltration, use of adequate backup equipment, or an increase In the cap" at the system, This provision is not
satisfied if, in the exercise of eeasoeabie errglneerhtj Judgment. the Permittee should have installed audliary or aihlltionatcoGeetbons system components, wastewater
retention or treatment facilities, adequate back-up equipmentorshouid have reduced Inflow and infiltration: or
(b.l The SSO was exceptional, unintentional, temporary, and caused byfactors beyond the reasonable control of the Farmlttee: the SSO could notftave been prevented
by the exercise of reasonable control, such as proper management, operation, and maintenance: adequate treatment or collection facilities or components (e4,
adequately enlarging treatment of collection faciibes to accommodate~h or adequately controlling and preventingInAlretion and Inilowl: preventative
maintenance: or Installation of adequate back-up equipment;"

Incident Number 0 202201041— 07/04/2022— 7703 Oak Marsh Dr., Raleigh NC
This spill was neither willful nor Intentional; it resulted from a failed 6" ductile iron sewer forced main. This
asset failure led to a sewer spill of approximately 1,600 gallons of untreated wastewater remaining within the
natural topography and not reaching surface water of the state (see exhibit 1— Area of Operation).
On Monday, July 4th, 2022, at approximately 12:05 PM, Raleigh Water Utility Responders were notified of
wastewater emanating from the ground near 7703 Oak Marsh Dr., Raleigh. The responding staff took all
reasonable steps to stop and mitigate the impact of the discharge as soon as they arrived, gaining control of the
spill event by 2:05 PM.
Utility Responders were able to contain and collect the wastewater by utilizing vacuum trucks in tandem and
controlling wastewater flow from the nearest pump station. Crews were able to collect the untreated
wastewater flow in tanks preventing the wastewater from continuing downstream. The natural topography of
the surrounding land, downstream of the affected asset, served to partially contain approximately 1,600 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 —Temporary containment. This spill was
temporarily 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, repair crews replaced the damaged section of force main (see
Exhibit 3 - Damaged Pipe and Subsequent Repair). The repair was made possible by reducing wastewater flow at
the nearby pump station. Once the force main was excavated, crews applied a 36W containment band replacing
approximately 4 ft. of ductile iron pipe. Once the repair was completed, the force main was pressurized to verify
the effectiveness of the repair, and no subsequent leaks or repair failures were noted. Crews restored the site by
backfilling the excavation with stable structural aggregates and restoring the ground surface with seed and
straw. Sewer -contaminated soil was mechanically removed and the area surrounding the pipe break was
cleaned with ample potable water to remove sewer traces from the surrounding area, and downstream
conveyance. The area was then treated with an application of lime and restored with grass seed and straw. See
Exhibit 4 — Site Restoration.
The cost associated with the mitigation of this event (including the repair efforts) amounted to $5,208.3S. The
approximate cost to the Utility to have treated 1,600 gallons of wastewater would have been approximately
$2.40. 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.

A press release notification was requested to be published in the Raleigh News & Observer as required by NCGS

event. This site continues to remain an active spot pending the completion of further Capital Improvements.

Incident Number # 20220119S — 07/26/2022 — 6321 Winter Spring Dr., Wake Forest NC
This spill was neither willful nor intentional. It resulted from a broken r PVC pipe located 40' upstream from
sewer manhole SMH130985. This pipe failure restricted the normal flow of untreated wastewater leading to the
sewer spill of approximately 3,600 gallons of untreated wastewater reaching an unnamed tributary within Smith
Creek Basin. See Exhibit 1—Area of Operation and Damaged Section of Pipe.

On 07/26/2022, at approximately 10:41 AM, Raleigh Water staff responded to a sanitary sewer overflow
emanating within an unnamed tributary located near 6321 Winter Spring Dr., Wake Forest NC. The responding
staff took all reasonable steps to stop and mitigate the impact of the discharge, gaining control of the spill event
by 02:15 PM on the same day.
Containment and collection of this spill event consisted of emplacing a sewer bypass and rerouting untreated
wastewater flow from manhole SHM132959 to manhole SMH130985 thus isolating the damaged segment of the
sewer main from continuing to flow into the stream (see Exhibit 2 — Bypass Operation). This approach was
Intended to contain wastewater flow and minimize the environmental impact on the surrounding land.
Responding crews also employed debris pumps at the temporary containment site to recover untreated
wastewater and any evidence of sewer debris 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, repair crews replaced the damaged section of the sewer gravity
main (see Exhibit 3 — Sewer Main Repair Effort). The repair was made possible by eliminating wastewater flow
utilizing a sewer bypass (see Exhibit 3 — Sewer by-pass). Once the sewer gravity main was excavated, crews
applied a 360' containment band replacing approximately 20 ft. of ductile iron pipe. Once the repair was
completed, the sewer main was inspected through CCTV to verify the effectiveness of the repair. CCTV
confirmed that no subsequent leaks or repair failures were noted. Crews restored the site by armoring the
creek's bank with stable structural aggregates and restoring the ground surface with seed and straw. Sewer -
contaminated soil was mechanically removed and the area surrounding the pipe break was cleaned with ample
potable water to remove sewer traces from the surrounding area, and downstream conveyance. The area was
then treated with an application of lime and restored with grass seed and straw. See Exhibit 4 — Site Restoration.

Exhibit 0 - Ske Retomdon
The cost associated with the mitigation of this event (including the repair efforts) amounted to $47,208.83. The
approximate cost to the Utility to have treated 3,6W gallons of wastewater would have been approximately
$5.40. 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 within a residential area. It provides sewer collection services to
approximately 360 residences. This specific portion of the collection system has not experienced an SSO event
within the last ten years.

event. This site continues to remain an active maintenance spot.

Incident Number B 202201201— 7/27/2022 — US 70-BR E., Garner, NC
This spill was neither willful nor intentional; it resulted from an obstruction In the invert Impeding the normal
flow of untreated wastewater. This obstruction resulted in approximately 4,800 gallons of untreated wastewater
to reach White Oak Creek located within the White Oak Basin. See Exhibit 1— Debris in the manhole.
On 07/27/2022, at approximately 1.45 PM, Raleigh Water staff responded to a sanitary sewer overflow
emanating from a sewer manhole near the exit ramp of US HW 70 East, Garner, NC. The responding staff took all
reasonable steps to stop and mitigate the impact of the discharge, gaining control of the spill event by 3:57 PM
on the same day.
FAIM 1— Mbrb in the manhole
Crews utilized hydraulic jetting and manual tools to remove the source of the blockage from the affecting asset
thus restoring sewer flow. Upon further assessment it was observed that the cause of the blockage was a
dislodged manhole step that laid at the bottom of the manhole invert causing a disruption of normal flow. It was
also noted that although grease did not contribute to the spill, there was grease accumulated within the
confines of downstream manholes. As a precaution a temporary spill containment site was emplaced
downstream of the affected area to contain the flow of untreated wastewater and minimize the environmental
impact to the surrounding land. The manholes found to have grease accumulation were serviced with hydraulic
jetting and degreaser.
Restoration of this spill event consisted of washing the land surrounding the affected asset. 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.

Fth4R3 -R"Umbn900
The cost associated with the mitigation of this event amounted to approximately $3,88S.92. The approximate
cost to the Utility to have treated 4,800 gallons of wastewater would have been approximately $7.20. 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 sanitary sewer collection system services a vast commercial complex housing several food -
service establishments within the Gamer Service area. A F.O.G. consultation found only two restaurants (out of
29) not in compliance and subsequently were assessed notice of violations.
There have been no additional issues associated with this section of the collection system since the last sewer
event. This site remains an active maintenance spot. A press release notification associated with this event was
requested to be published in the Raleigh News & Observer on July 28th, 2022 (see Exhibit 4 — Press Release).

Incident Number 8 202201209 — 07/28/2022 — intenection of Major Slade Rd / Smithfeld Rd, Knightdale, NC
This spill was neither willful nor intentional; it resulted from a failed 16' Polyvinyl Chloride Pipe force main. This
asset failure led to a sewer spill of approximately 4,000 gallons of untreated wastewater to spill unto the land.
Approximately 1,000 gallons reached an unnamed tributary within Poplar Basin (see exhibit 1— Area of
Operation).
On Thursday, July 2r, 2022, at approximately 6:45 AM, Raleigh Water Utility Responders were notified of
wastewater emanating from the ground near the intersection of Major Slade Rd & Smithfield Rd, Knightdale, NC.
The responding staff took all reasonable steps to stop and mitigate the impact of the discharge as soon as they
arrived, gaining control of the spill event by 3:08 PM,
Utility Responders were able to contain and collect the wastewater by utilizing vacuum trucks and controlling
wastewater flow from the nearest pump station, The natural topography downstream of the affected asset, and
the excavation surrounding the affected force main served to partially contain approximately 3,000 gallons of
untreated wastewater before it reached surface waters. See Exhibit 2 — Temporary containment. This spill was
temporarily 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.
12

During the restoration phase of the operation, repair crews replaced the damaged section of force main (see
Exhibit 3 - Damaged Pipe and Subsequent Repair). The repair was made possible by reducing wastewater flow at
the nearby pump station. Once the force main was excavated, crews applied a 350' containment band replacing
approximately several feet of ductile iron pipe. Once the repair was completed, the force main was pressurized
to verify the effectiveness of the repair, and no subsequent leaks or repair failures were noted. Crews restored
the site by backfilling the excavation with stable structural aggregates and restoring the pavement to travel
conditions. Sewer contaminated soil was mechanically removed and the area surrounding the pipe break was
cleaned with ample potable waterto remove sewer traces from the surrounding area, and downstream
conveyance. See Exhibit 4 — Site Restoration.
13

The cost associated with the mitigation of this event (including the repair efforts) amounted to $18,809.16. The
approximate cost to the Utility to have treated 4,000 gallons of wastewater would have been approximately
$6.00. 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.
A press release notification was requested to be published In the Raleigh News & Observer as required by NCGS

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 66.58111 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
$ 885,577.46121, approximately .06% of the Division's annual operating budget. The 14,000 gallons of untreated
wastewater spills Identified in this letter cost the Utility approximately $75,112.26. to mitigate. The City's cost of
sewer treatment per gallon is $.0015131. At this rate, It would have cost the City $21.00 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
0.65 total SSO rate 14' per 100 miles of pipe, compared to the Southeastern Region of the US, of 7.0 spills per 200
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.
15

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.11raleiahnc.novisewer-maintgnan;
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-NOI.0236 issued for the month of July 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

sewer main. A tem ora containment site was established 2:00 pm on 437 Boardwalk Dr. utilizing a 4 gumpandstr�
to prevent any untreated wastewater from reaching further down stream utilizing SMH100221 to reintroduce back into the
sewers stem. A bypass plug was established and started 0,215 om diverting sewer from SMH132959 to SMH130985.
Sewer maintenance crews started a hydrant at 2:30 on the intersection of Winter Sorina Dr & Silent Brook Rd to assist wi
the flushin-q of the creek. Crews are still on site flushing the creek and easement crews are working diligently to gain
access to the easement for the re air crews. Once crews ained access the repair crews removed the damacled section a
