Dear Mr. Massengill:
This letter transmits a Notice of Violation and assessment of civil penalty in the amount of $785.67 ($750.00 civil penalty -
$35.67 enforcement costs) against City of Raleigh.
This assessment is based upon the following facts: a review has been conducted of the Sanitary Sewer Overflow (SSO)

summarized in Attachment A to this letter.
Based upon the above facts, I conclude as a matter of law that City of Raleigh violated the terms, conditions or
requirements of Collection System Permit No. WQCS00002 and G.S. 143-215.1(a)(1) in the manner and extent shown in
Attachment A. In accordance with the maximums established by G.S. 143-215.6A(a)(2), a civil penalty may be assessed

Based upon the above findings of fact and conclusions of law, and in accordance with authority provided by the
Secretary of the Department of Environmental Quality and the Director of the Division of Water Resources, I, Scott
Vinson, Regional Supervisor, Raleigh Regional Office hereby make the following civil penalty assessment against City of
Raleigh:
$750.00 For 2 of the 2 violations of Collection System Permit No. WQCS00002 and G.S. 143-215.1(a)(1) for

$750.00 TOTAL CIVIL PENALTY
$35.67 Enforcement Costs
$785.67 TOTAL AMOUNT DUE
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-282.1(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
Management Commission has regulatory authority; and
(8) The cost to the State of the enforcement procedures.
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 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
Remission Request."
Both forms should be submitted to the following address:
Attn: PERCS Branch
Division of Water Resources
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
AND
Scott Vinson, Regional Supervisor
Water Quality Regional Operations Section

Division of Water Resources, NCDEQ
1628 Mail Service Center, Raleigh
Raleigh, NC 27699-1628

Option 3: File a petition for an administrative hearing with the Office of Administrative Hearings:
If you wish to contest any statement in the attached assessment document, you must file a petition for an administrative
hearing. You may obtain the petition form from the Office of Administrative Hearings. You must file the petition with
the Office of Administrative Hearings within thirty (30) days of receipt of this notice. A petition is considered filed

the signed original, one (1) copy and a filing fee (if a filing fee is required by NCGS §150B-23.2) is received in the
Office of Administrative Hearings within seven (7) business days following the faxed or electronic transmission. You

Raleigh, North Carolina 27699-1601
Please indicate the case number (as found on page one of this letter) on the petition.
Failure to exercise one of the options above within thirty (30) days of receipt of this letter, as evidenced by an internal
date/time received stamp (not a postmark), will result in this matter being referred to the Attorney General's Office for
collection of the penalty through a civil action. Please be advised that additional penalties may be assessed for violations
that occur after the review period of this assessment.

Dear Mr. Massengill:
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:

days of its receipt. In your response, you should address the causes of non-compliance,
remedial actions, and ail 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

Dear Mr. Vinson:
NC Dept of Environmental Quality
AUG 10 ?ucd
Raieigh Regional Office
Please allow this letter to serve as a response to the Notice of Violation & Intent to Issue Civil Penalty
document (NOV-2021-DV-0318) received on July 27th, 2021. This document contains the narratives regarding a
pending violation actions of (2) Sanitary Sewer Overflow (SSO) events, which occurred during the month of July
2021 within the City of Raleigh Collections Systemill. J. This document also provides exhibits as proof of our
efforts to mitigate the sewer event. 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 wastewater;
collect the wastewater and reintroduce it to the collection system; and finally, restoring the possible
environmental impacts brought by the release of the 5S0 events, listed with the intended NOV-NOI action.
Please find below, the additional information requested for the three SSO events.
]. "The Director may take enforcement action against the Permlttee for SSOs that must be reported to the Division as stipulated In Condition IV92). This includes SSOs that were
caused by severe natural conditions or exceptional events unless the Permlttee demonstrates through properly signed, contemporaneous operating logs, or other relevant
evidence that
Ia.] 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 Permhtee should have Installed auxiliary or additional collections system components, wastewater retention or treatment
faclities, 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 # 202101463 — 06/28/2021— 0 Harris Rd, Raleigh, NC
This spill was neither willful nor intentional. It resulted from a grease build-up, restricting the sewer flow
within an 8" Vitrified Clay pipe gravity sewer main section. This build-up led to a sewer spill of approximately
7,880 gallons of untreated wastewater, reaching an unnamed tributary within the Richland Wake Forest Basin.
(See exhibit 1— SSO Area of Operation, p.4)
On 06/28/2021, at approximately 5:15 PM, Sewer Maintenance staff was notified of a sewer spill
emanating from a manhole located near 0 Harris Rd, Wake Forest. The responding staff arrived shortly after and
commenced taking all reasonable steps to stop and mitigate the impact of the discharge, gaining control of the
spill event by 11:47 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 two temporary spill containment
sites downstream of the affected area. 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 sites 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 area surrounding the manhole and the downstream conveyance. The
areas around the manhole were cleared of debris and washed with potable water. The area around the manhole
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 07/14/2021 to identify the root cause of grease
accumulation. The CCTV assessment is ongoing pending further sewer main cleaning.
The cost associated with the mitigation of this event amounted to $ $5,536.68. The approximate cost to
the Utility to have treated 7,880 gallons of wastewater would have been approximately $11.82. 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 in a residential area. it provides sewer collection services
to over 430 properties upstream of the spill event (see Exhibit 2- Zone of Influence, p4). Before the event on
June 28th, this portion of the collection system experience two separate SSO events: 2/13/2010 Harris Rd
Easement SSO, Asset I.D. SGMN116109 and 7/11/2005 201 Harris Rd. SSO, Asset I.D. SGMN108589.
A press release notification associated with this event was requested on 6/29/2021 (see exhibit 3 -Press
release, p.5). Outreach information literature was also requested to be sent to the immediate -affected area.
The requested outreach literature would explain 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 # 202101469 — 06/29/2021— 6601 Times Dr, Raleigh, NC
This spill was neither willful nor intentional. It resulted from a grease build-up, restricting the sewer flow
within an 8" gravity sewer main section. This build-up led to a sewer spill of approximately 2,800 gallons of
untreated wastewater, reaching an unnamed tributary within the Perry Basin (See exhibit 1— SSO Area of
Operation, p8)
On 06/29/2021, at approximately 3:46 PM, Sewer Maintenance staff was notified of a sewer spill
emanating from a manhole near 6601 Times Dr, Raleigh, NC. The responding staff arrived shortly after and
commenced taking all reasonable steps to stop and mitigate the impact of the discharge, gaining control of the
spill event by 5:44 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 two temporary spill containment
sites downstream of the affected area. 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 sites 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

downstream waters confirmed that no fish kill or unnecessary vegetative damage occurred.
During the restoration phase of the operation, crews utilized ample potable water to flush the affected
area and remove sewer traces from the area surrounding the manhole and the downstream conveyance. The
areas around the manhole were cleared of debris and washed with potable water. The area around the manhole
was cleared of debris, treated with an application of lime, and restored with grass seed and straw.
A follow-up CCTV assessment was conducted immediately following the sewer event of 06/29 to identify
the root cause of grease accumulation, The CCTV assessment is ongoing, pending further sewer main cleaning.
The cost associated with the mitigation of this event amounted to $10,074.11. The approximate cost to
the Utility to have treated 2,800 gallons of wastewater would have been approximately $4.20. 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 provides sewer collection services to approximately 228 properties
upstream of the spill event. Two hundred two of these properties are serviced by a private sewer system in
which Raleigh Water has no jurisdiction of maintenance or treatment of grease accumulation in their private
sewer collection system (see Exhibit 3- Zone of Influence, p9). Before the event on June 29th, this portion of the
collection system experienced three separate SSO events: 12/11/06 (6531 Meridien Dr); 2/9/05 (easement off
6541 Meridien Dr.); and 1/8/2003 (easement behind 6541 Meridien Dr). This site has been identified as an area
for repeated maintenance.
A press release notification associated with this event was requested on 6/29/2021 (see exhibit 2, p.9).
Outreach information literature was also requested to be sent to the immediate -affected area. The requested

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 2600 miles of sanitary sewer pipe and minimize the accidental release of untreated
wastewater.
Since July 1, 2020 (Fiscal Year 2021), the Utility has maintained approximately 428.40 [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
3,581,811.42 [2], approximately 28%ofthe Division's annual operating budget. The 10,680 gallons of untreated
wastewater spill identified in this letter cost the Utility approximately $15,610.79 to mitigate.
The City's cost of sewer treatment per gallon is $.0015 [3]. At this rate, it would have cost the City $16.02 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 2.21 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.

Additionally, the City of Raleigh Assistant Public Utility Directors and Collections System staff has
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
10

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 https://raleighnc.gov/sewer-maintenance
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-2021 NOI-0264 issued for the month of
May 2021 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 T.J. Lynch, Assistant Raleigh
Water Director, at [phone].

minimize the environmental impact to the surrounding land. Crews utilized potable water to flush the area and to 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 assessment will follow
