ROGERS, JR. Director Mr. John Kiviniemi Assistant Director of Raleigh Water City of Raleigh P.O. Box 590 Raleigh, NC 27602-0590 NORTH CAROLINA Environmental Quality September 22, 2023 Subject: Compliance Evaluation Inspection City of Raleigh Sewer Collection System Collection System Permit No: WQCS00002 Wake County Dear Mr. Kiviniemi: On June 30,2023, Cheng Zhang and Kevin Fowler of the Raleigh Regional (RRO) Office Division of Water Resources conducted a Compliance Evaluation Inspection of the subject facility. The assistance and cooperation of you, Mr. Matt Vessie, the Utilities Manager, Mr. Carlos Perez, the Operator in Responsible Charge (ORC), and many other members of your staff during the inspection, were very helpful and appreciated. A checklist of items is enclosed with this letter. During the inspection the following items were noted: 1.) The City's collection system is classified as a Class 4 collection system. It has approximately 2,468 miles of gravity sewer mains, 134 miles of force main, 517 simplex pump stations that discharge to a pressure sewer and serve a single building, 4 simplex pump stations serve more than one building, and 123 duplex pump stations. Mr. Carlos Perez is the Operator in Responsible Charge (ORC) and Mr. Jeffrey Bognar, Mr. David Collins, Mr. David Jackson, Mr. Manuel Lopez, and Mr. Chris Worthy are the backup ORCs. 2.) The City has a GIS based collection system map which has all items required by the permit. 3.) The City has adopted a Sewer Use Ordinance and established inter -local agreement with Town of Clayton in Johnston County. 4.) The City has developed and implemented a Capital Improvement Plan (CIP) for the sewer system, which includes all components required by the permit. Current CIP covers a ten-year period (2021 to 2030). The CIP covers sewer interceptor upgrades, sewer main replacement under Asset Management Plan (AMP), pump station upgrades, and miscellaneous sewer improvement. 5.) The system has 123 duplex pump stations, all stations were equipped with SCADA. Major pump stations are inspected daily, others weekly. Five pump stations were visited during the inspection.

The City has developed and implemented a Fats Oils and Grease (FOG) program. Grease traps/interceptors at restaurants are inspected by the City's Fat/Oil/Grease Program inspectors. It was noted that distribution/mailing of FOG educational material has not been conducted and documented in the past several years, due to the City's information vetting policy. 15A NCAC 02T .0108 (b) requires at least semiannual distribution of FOG educational material targeted at both residential and nonresidential users. It was noted that FOG educational material and water/wastewater reports are posted on the City's website and available to consumers. The City has implemented an aggressive educational outreach initiative that addresses illicit discharges such as wipes, fats, oil, and grease to commercial and residential users. The City developed a complimentary property managers resource kit for residential users that provides best practice resources for establishing a property -specific awareness program. The City continues its monetary reward or bounty program to promote pollution prevention, 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. The City 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. With consideration of these initiatives the City has taken, distribution of FOG educational material can be reduced to annually. 7.) The City has developed and implemented a spill response action plan; the plan was updated in June 2023 and found adequate. 8.) A review of records and logbooks indicate the following: a) Records are maintained adequately for sewer line maintenance, cleaning, high priority line inspection, and right of way maintenance. All maintenance and inspection records are kept in Cityworks program. The City is behind the schedule in sewer easement maintenance due to the Covid pandemic, has developed a strategy by classifying sewer easements into four categories and acting accordingly to ensure easement is accessible should a spill happens. b) 174 Sanitary Sewer Overflows (SSOs) were discovered or reported since the last inspection. Required SSO reports, press releases, and public notices were available for review. 9.) The City has designated over eleven thousand high riority/aerial lines; these lines are inspected semi- annually. Two siphon boxes were observed during the inspection, which were in good condition, the right-of-way to these lines was well maintained.
