This document contains the narrative regarding a pending violation actions of (3) Sanitary Sewer Overflow (SSO) events, which occurred during the month of October 2021 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 event 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 SSO event, listed with the intended NOV-NOI action. Please find below, the additional information requested for the SSO event. 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 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 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;" 1 Incident Number # 202102084 — 10/25/2021 — 1902 Glenwood Ave., Raleigh, NC This spill was neither willful nor intentional; it resulted from a partially collapsed 6-inch vitrified clay sewer gravity main. Although no active SSO was witnessed during the discovery of the failed pipe, the presence of paper debris was indicative of a previous sewer spill. Based on open channel estimation, hydraulic modeling, and the amount of flow recovered from a downstream containment and collection site, it was determined that the approximate volume of the spill was 5,000 gallons. The wastewater reached approximately 3,720 ft downstream on Oxford Branch Tributary to Crabtree Creek. On 10/25/2021, at approximately 6:48 am, Utility Operators identified sewer debris on the ground near the base of sewer manhole SMH153636. A close television inspection identified that a portion of the vitrified clay pipe had collapsed (see exhibit,1 - Partial collapse) leading to a subsequent sewer overflow reaching the stormwater channel below..The responding staff took all reasonable steps to stop and mitigate the impact of the damage as soon as they arrived, restoring the sewer gravity main at approximately 03:45 PM on the same day. Repair crews were able to replace approximately 9 ft of vitrified clay sewer gravity main with PVC pipe restoring the sewer flow within the system (see exhibit 2 — Repaired main). Containment and collection of this spill event consisted of employing a temporary spill containment at approximately 3,720 ft downstream of the affected area. This approach was intended to contain wastewater flow and minimize the environmental impact on the surrounding surface waters of the state. Responding crews employed a pump at the temporary containment site to recover wastewater and any evidence of wastewater completing the operation by re -introducing the wastewater to the collection system. During the restoration phase of the operation, crews utilized ample potable water to flush and remove wastewater debris from the affected area, including the manhole and the creek. 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. The cost associated with the mitigation of this event amounted to $8,225.23. The approximate cost to the Utility to have treated 5,000 gallons of wastewater would have been approximately $7.50. 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 portion of the sanitary sewer collection system serves a residential area east of Glenwood Avenue. It has been identified as a hot spot for recurrent assessment. Portions of this sewer collection system have been assessed as follows: Flushing activities Clean 5/28/2020 Clean 9/28/2020 Clean 10/7/2020 CCTV Activities CCTV 2/22/2018 CCTV 2/26/2018 CCTV 5/10/2019 CCTV 10/25/2019 CCTV 5/28/2020 CCTV 9/15/2020 CCTV 10/25/2021 CCTV 10/26/2021 CCTV 11/2/2021 Repair Activities Invert Repair 12/3/2018 Point Repair 8/25/2020 Point Repair 10/26/2021 Ring and/or Cover Replacement 11/15/2021 2 A press release notification associated with this event was published in the Raleigh News & Observer on 10/26/2021 (Exhibit 3 — Press release).

The bore -through resulted in the sewer spill of approximately 3,600 gallons of untreated wastewater of which approximately 1,000 reached an unnamed tributary within Pigeon House Basin. On 10/18/2021, at approximately 1:30 PM, Raleigh Water staff was notified of a sewer odor near a service road located behind 120 Forest Rd., Raleigh, NC. The responding staff took all reasonable steps to identify the source of the odor, stop and mitigate the impact of the discharge as soon as they arrived, gaining control of the spill event by 4:30 PM on the same day. Crews utilized CCTV to identify the source of the odor determining that the damaged sewer pipe was the direct result of a utility pole being buried directly through an 8-in vitrified clay sewer gravity main (see exhibit 1- Ruptured sewer main and excavated utility pole). Utility responders immediately established a sewer bypass to re-route sewer flow downstream of the damaged pipe. The utility pole owner (AT&T) was immediately contacted to remove and relocate the pole. Crews also utilized hydraulic jetting to dislodge and remove debris that has entered the sewer main as a result of the buried utility pole. Exhibit 1—Ruptured sewer main and excavated utility pole USMH: SMH109743 DSMH: SMH150396 Miscellaneous Survey Abandoned Containment and collection of this spill event consisted of employing a temporary spill containment site downstream of the affected area. This approach was intended to contain sewer flow and minimize the environmental impact on the surrounding land. Responding crews initiated the collection of untreated wastewaters from the containment site to re -introduced it to the collection system downstream. Cleanup consisted of removing and disposing of sewer debris from the excavation. The area around the affected sewer gravity main was washed with potable water and the surrounding area was decontaminated with the application of lime, grass seed, and straw. 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 occurred. 6 Raleigh Water completed the repair of the damaged sewer main, by replacing the damaged section of the main with PVC pipe and the utility poled was re -positioned accordingly (see exhibit 2- Repair efforts). A Code Enforcement action was issued to assess the damage and to assign the associated cost of the incident against the contractor. Exhibit 2- Repair efforts The cost associated with the mitigation of this event amounted to $14,734.32. The approximate cost to the Utility to have treated 3,600 gallons of wastewater would have been approximately $5.40. The City saved no money from this spill. The costs for cleanup and repair 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 volume of sewage created by the spill as well as the cost of potable water used to mitigate the event. A press release notification associated with this event was requested to be published in the Raleigh News & Observer on 10/19/2021 (Exhibit 3 — Press release).

This news release is required by NCGS Article 21, Chapter 143.215.1C. �nvicoa�enta, Quality NC Dept of /C 0 "Raleigh Regional Office 11 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 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% of the Division's annual operating budget. The 16,000 gallons of untreated wastewater spill identified in this letter cost the Utility approximately $24,826.46. to mitigate. The City's cost of sewer treatment per gallon is $.0015 [3]. At this rate, it would have cost the City $24.90 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.

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. 12 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 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-0464 issued for the month of October 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.
