EXECUTIVE SUMMARY The City of Greenville has completed its thirteenth annual report to the NC Division of Water Resources. This report highlights the following components of our Stormwater Management Program: I. Executive Summary II. New Development Review/Approval III. Compliance and Enforcement IV. Illegal Discharges V. Retrofit Opportunities VI. Public Education VII. Additional NPDES MS4 Components The appendices provided include summary tables for new development, illicit discharge violations and public education back-up information. In addition, the following are updates to programs or projects managed by the City of Greenville’s Stormwater Management Section to address community issues associated with stormwater runoff. Stream Enhancement Program Update: The Stream Enhancement Program addresses bank erosion along blue-line streams in an effort to improve water quality, property values and protect the safety of citizens. The program was intended to provide an avenue for property owners to apply for funding from the City to address eroded blue-line stream banks located on private property. This program is typically funded through the Stormwater Utility. During the report period the City received 5 applications for funding. 2 applications were approved for funding and contracted during the 2017-2018 budget year. 1 application was received past the cutoff date for the 2017-2018 budget year and is scheduled to be contracted for the 2018-2019 year. 1 application did not meet the criteria to be eligible for funding and 1 is in review. The City will continue to accept applications and rank projects and will resume this effort in 2018 with available funds for eligible projects with any remaining funds to be utilized for other stream restorations identified in the Watershed Master Plans. Watershed Master Planning Update: Since the completion of all 7 of the Watershed Master Plans, staff has presented at several civic organizations and technical workshops about the effort and its value to the City. These include local neighborhood associations, national public works conference (PWX), IECA, and NC APWA. The City’s master plans capture public infrastructure and develop and prioritize projects for both flood retention and water quality throughout the city. The goals of the WMP included: (1) evaluating the watershed for existing flooding, water quality, and erosion problems, (2) recommend and prioritize capital improvement projects to mitigate existing flooding by reducing the frequency and severity of flooding for property owners, (3) identifying stream stabilization projects to reduce the risk of property loss along streams and reduce sediment loads as a result of erosion and (4) identify stormwater BMP retrofit locations to address runoff from existing impervious areas in order to minimize negative impacts to water quality in the receiving waters. COG-#1114085-v1-2017-2018_COG_Tar-Pam__NPDES_MS4_Annual_Report Page 3 of 38 8/30/2019 Long-Term Operation and Maintenance of Structural Stormwater BMPs Update: The City continues to recognize the importance of long-term maintenance and intends to develop policies and procedures to address the long-term operation and maintenance of structural stormwater BMPs associated with residential subdivision development. Currently, the residential developer turns the long-term operation and maintenance of structural stormwater BMPs over to a Home Owners Association (HOA) once the development or a portion of the development is completed. Residential developments that have been built since the implementation of the State regulations will soon be of an age where extensive maintenance and vegetative/nuisance management are required to keep the facilities functioning as designed. Thereafter, HOA’s are then unable financially to meet the routine and extensive maintenance program requirements, which then leads to complications for both the City and HOAs to ensure compliance with long-term operation and maintenance requirements. It is the City’s goal to develop policies and procedures in the future to address and alleviate these complications. This will be a topic of discussion with the upcoming Stormwater Advisory Committee. Stormwater Advisory Committee and Utility Rate Study: The establishment of this stakeholder’s group was a natural outgrowth of the City’s forward- thinking Watershed Master Planning (WSMP) process, the results of which were presented to the City Council on August 25, 2016. The Master Plans took a holistic look at the City’s drainage basins and stormwater management program to identify current and future needs both in terms of infrastructure and programming to reduce the severity, duration, and frequency of flooding, stabilize streambanks, and provide water quality treatment for impaired watersheds. The total implementation cost identified in the Master Plans for capital projects is approximately $170 Million in 2016 dollars. Additionally, the City will be required to replace aging infrastructure nearing the end of its life cycle. Staff currently estimates the maintenance cost to replace this infrastructure over a 40-50-year timeframe is approximately $230 Million. When evaluating these needs in comparison with current revenues, it became clear that there is a growing deficit that must be addressed. The City has contracted with a consultant to help facilitate a Stormwater Advisory Committee (SWAC) to complete a stormwater level of service and rate assessment linking capital improvement needs, financing and policy. The SWAC has met a total of 11 times (10 in this reporting period) starting in early 2017 through July of 2018. The first two meetings early in 2017 provided introductory material to the committee members regarding the City’s Stormwater Program, its utility funding, and the objectives of the committee. Meetings 3 through 11, starting in October 2017, addressed the following topics: • Extent of Service (EOS) – Where should the City provide stormwater services? COG-#1114085-v1-2017-2018_COG_Tar-Pam__NPDES_MS4_Annual_Report Page 4 of 38 8/30/2019 • Level of Service (LOS) – What is the type and frequency of service the City should provide? • Financial Analysis – Are changes to the utility rate structure and rates necessary to provide the recommended EOS and LOS. • Capital Spending Plan - How should capital projects be prioritized? Presentations were provided by the consultant team and City staff to educate the SWAC on the current practices and budgets of the City’s Stormwater Program. Within those presentations, the consultant team identified key areas that can impact the extent of service and level of service of the City’s Stormwater Program. The SWAC then discussed those areas to develop recommendations. Despite the stakeholders’ diverse backgrounds and differing vested interests, the group unanimously supported a higher level of service. They also unanimously recommended an increase to stormwater utility fees to achieve the desired levels of service and fund the substantial capital improvement program and infrastructure replacement needs determined necessary to ensure a sustainable stormwater program. A final report including recommendations on extent and level of service as well as a rate increase and capital spending plan will be presented to City Council in the next few months. The committee will continue to meet to further evaluate city ordinance and policy changes. COG-#1114085-v1-2017-2018_COG_Tar-Pam__NPDES_MS4_Annual_Report Page 5 of 38 8/30/2019 II.

COG-#1114085-v1-2017-2018_COG_Tar-Pam__NPDES_MS4_Annual_Report Page 8 of 38 8/30/2019 IV. PROGRAM ELEMENT: Illegal Discharges In accordance with the Tar-Pamlico River Basin – Nutrient Sensitive Water Management Strategy: Basinwide Stormwater Requirements, the City of Greenville developed an Illicit Discharge/Connection Program. This program establishes the process and legal authority to detect and eliminate any illegal discharge or connection within the city limits and up to 1 mile outside the contiguous city limits. The table presented on the next page is a summary of the violations that were investigated during this permit cycle and the resulting action taken. In addition, Appendix B includes copies of the initial reports. As noted in the table several of the issues were reported to the City by crews working on the WSMP. The City also continued to issue multiple door hanger notices throughout the year at residences and businesses to provide education on the impacts of placing lawn debris and other materials in the street. The City of Greenville continues to rely on the NC Department of Environment and Natural Resources Environmental Help Line for water quality concerns in our area. The number is 1- 877-623-6748. We did not receive any calls as a result of the state hotline during this permit cycle. In addition, through our pollution prevention education efforts, reports on water quality concerns have continued to be regularly received at the Public Works Department. As presented in previous Annual Reports, the City of Greenville has completed the collection and organization of jurisdiction-wide information identified in the permit. This information was compiled from various resources such as Greenville Utility Commission’s GIS database, City of Greenville’s GIS database, NC Division of Water Quality records and NC Division of Environmental and Natural Resources records. We have completed our annual update of this information. As part of Section 3-E in the City of Greenville Stormwater Management Program (COG SMP), the City conducted dry weather field screening of outfalls in a specified area. To select the area, a map was created showing all seven watersheds within the City’s jurisdiction. Due to the size, feasibility, and location within what the City determined to be a high risk area; the Hardee Creek watershed was chosen which represents approximately 10% of the geographic jurisdiction area. There were 18 outfalls in this area that fit the criteria outlined in the COG SMP. Each of the 18 outfalls in this area were observed to either have standing water or some element of flow. This is because a blue line stream was passing through every outfall. To be certain that the water in these outfalls were not results of illicit discharge, pH and chlorine tests were performed. None of the samples showed levels of either above what would be expected in ground or surface water.

PROGRAM ELEMENT: Retrofit Opportunities As discussed in the Executive Summary, the City of Greenville completed all of the Watershed Master Plans. Throughout this planning process numerous locations were identified by citizens, staff and the consultant (via stream walks) that were either severely eroded or had the potential for a structural BMP. All locations were assessed and viable locations were prioritized. A stakeholders group will be formed to further prioritize projects on a City-wide level. The table below identifies the top 12 water quality and/or stream stabilization projects across the Meetinghouse Branch Watershed and the estimated cost to design and construction the retrofit: The project assessment, summary, and map of projects and the project summaries, and sizing calculations are included on the following pages.

PROGRAM ELEMENT: Additional NPDES MS4 Components The City of Greenville’s NPDES MS4 Permit #NCS000437 requires that the City implement its Stormwater Management Plan for the following measures: Post-Construction Site Runoff Controls Illicit Discharge Detection and Elimination (IDDE) Public Education and Outreach Public Involvement and Participation Construction Site Runoff Controls Pollution Prevention and Good Housekeeping for Municipal Operations Total Maximum Daily Loads (TMDLs) The MS4 permit Part IV, B. 2. States: Reports submitted to submitted to satisfy other State Stormwater Reporting requirements satisfy the annual reporting requirements of this permit to the extent that the reports satisfy Part III, paragraph B 1-5, Part IV, paragraph B 3 (c) and Part II Section I, Electronic Reporting [g.s. 143-215.1(b)] of this permit This section is included in this NSW report to ensure that it satisfies all additional NPDES measures and reporting requirements. Previously Described Measures The Post-Construction (section II & III), IDDE (section IV), and Public Education (section VI) are all required components of our NSW program and are detailed in the previous sections of this report. The City applies the NSW requirements across its entire jurisdiction in both the Neuse and Tar-Pam river basins. Public Involvement and Participation The Public Involvement and Participation measure is not specifically part of the NSW program but the City of Greenville implements this measure in tandem with its Public Education efforts and those results are detailed in section VI Public Education. Specifically the Public Involvement activities include Storm Drain Stenciling, Adopt-A-Street, and the SW Education Grant Program. Construction Site Runoff Controls The City of Greenville will rely on its locally delegated Erosion and Sediment Control Program established June 8, 1978. The City Of Greenville will rely on the NCDEQ to administer NPDES Stormwater Discharge Permit for Construction Activities (NCG010000). The City has established and maintains a 24-hour online reporting software to provide a means for concerned citizens and agencies to contact the appropriate authorities when they see water quality and erosion control problems. The City will record the number of concerns received and the number of problems/incidents remedied as a result of the entries. The City also relies on the state telephone hotline (NCDEQ “Stop Mud”) to provide this service as well. COG-#1114085-v1-2017-2018_COG_Tar-Pam__NPDES_MS4_Annual_Report Page 22 of 38 8/30/2019 Pollution Prevention and Good Housekeeping for Municipal Operations The municipal operations that will be impacted by this operation and maintenance program would be the following: the Street Maintenance Division, Buildings and Grounds Division, Sanitation Division, Fleet Maintenance Division, Transit Division, and Recreation and Parks Department Operation and Maintenance, which would include Bradford Creek Municipal Golf Course. List of Industrial Facilities Requiring Individual NPDES Permits:  City of Greenville Sand Pit- NCDENR- Division of Land Resources Mining Permit # 74-9.  City of Greenville Public Works Complex – NCG080000 Industrial Permit. The City maintains operation and maintenance procedures for all municipal facilities. The Public Works facility is also covered by a NCG08 industrial stormwater permit. Inspection, sampling, and maintenance procedures are detailed in the facility’s specific Stormwater Pollution Prevention Plan (SWPPP). Annual inspections are conducted by the Fire/Rescue Department and monthly by Public Works Staff to identify unsafe conditions, including the potential for discharging of hazardous materials. The City routinely conducts self-inspections to insure OSHA compliance. There are regular inspections and cleaning of oil separators associated with Fleet Maintenance located at the Public Works Complex. These oil separators were cleaned 2 times during the year and waste oil and used oil dry were disposed of by a professional environmental management contractor 3 times during the year. All paved areas within the Public Works Complex are swept on a semi-annual basis. Litter patrol, is performed on a weekly basis and as needed, collects debris and/or litter at the Public Works Complex. Salt is stored under storage until needed. Waste from street sweeping is stored on-site in a contained area until transferred to a certified landfill. A SWPPP for the Public Works Complex has been developed and is updated annually. The last update was completed on September 6th, 2018 and is scheduled to be updated again on September 4, 2019. All waste produced and collected as a result of maintenance operations is taken to a certified landfill, recycled, or spread and stabilized appropriately. The City maintains a written Spill Prevention and Response Plan as part of the SWPPP. City streets are swept on an ongoing basis by a fleet of 4 street sweepers that results in cleaning all city streets approximately 6 times per year. The City has an active street sweeping program that includes 263.82 miles of City maintained streets and 34 miles of State maintained streets. City staff will conduct semi-annual stormwater system inspections specifically of the stormwater system, of the stormwater controls, and for stormwater pollution potential at the City’ operations. Major culverts and open channels are policed for debris clogs after each major storm event. Pipe systems and catch basins are cleaned by hand with a vacuum truck based on flooding reports and COG-#1114085-v1-2017-2018_COG_Tar-Pam__NPDES_MS4_Annual_Report Page 23 of 38 8/30/2019 as identified through regular maintenance activities. Approximately 70 miles of streams/open channels are manually inspected/checked and cleared of obstructions twice a year. Most post-construction stormwater control structures are privately owned and maintained but the City does have a small number of municipal owned and maintained control structures. City owned and maintained stormwater control structures follow the same O&M agreements as do privately owned controls. The Engineering Division performs annual inspection of these structures and coordinates with the responsible department for appropriate maintenance efforts. The City ensures that all municipal employees and contractors are properly trained and certified for any pesticide, herbicide, or fertilizer application used and that appropriate measures are followed. The City conducted an initial training program of all employees that are actively involved in facility operations and routine orientation training of new employees about stormwater management; potential sources of contaminants; reduction in usage of fertilizers, pesticides, and water usage; and Best Management Practices to eliminate stormwater runoff pollution. Operational employees receive formal training and information through brochures, flyers, posters, employee meetings, bulletin boards, and with training that shows areas of potential stormwater contamination and associated pollutants. Employees in all relevant City departments/divisions are also trained on how to recognize an illicit discharge and respond appropriately, with may include containment, cleanup, disposal, and reporting as well as proper fueling procedures. As part of the City’s controls for reducing discharge of pollutants it does not permit steam cleaning wash water to enter the storm drain. Existing wash pits for street maintenance and Sanitation are plumbed through a separator to the wastewater sewer system. Vehicle and equipment fueling is provided at a protected designated fueling area. All discharges within Fleet Maintenance go through oil separators. These areas are pumped out and cleaned twice per year or more often as needed. The City continues to evaluate its Stormwater Management Program annually to ensure all measurable goals are being met and to plan strategies to address any differences identified. The review includes at least the following positions within the City: Public Works Director, City Engineer, and the Stormwater Engineer. A Stormwater Pollution Prevention Team meeting is held annually with representatives from the Street Maintenance Division, Buildings and Grounds Division, Sanitation Division, Fleet Maintenance Division, Transit Division, Recreation and Parks Department Operation and Maintenance, and the Engineering Division. Team members review inspection reports from the Engineering Division and discusses compliance and suggested improvements and adjustments to the plan and municipal operations and training.

The grant of $2,500 for stormwater management education for 2017 was awarded to Love A Sea Turtle (LAST) to support and expand the Paint the Drain initiative. Since last spring, LAST have planned to paint every storm drain in Greenville over the next five years. A mobile platform for the video, a simplified sign-up, easy to access supplies, and ready availability of maps detailing where to paint are some of their goals. All of this combined with public service announcements airing year round and modern posters in schools, clubs and community volunteer agencies are part of the planning process to educate the public and complete this project. During their summer camp program, Upstream Downstream Connection Camp, they introduce water quality concepts, current storm-water concerns, and paint drains when and where it is appropriate and weather permitting. Stenciling storm drains throughout Greenville will continue to bring continued awareness to the public about what goes into storm drains does not go through a water treatment center, but flows directly into ou rivers and streams and ultimately our oceans. Love A Sea Turtle served as project coordinator and liaison to the effort. City of Greenville Storm Water Management staff provided project support with stencil kit materials. City of Greenville Videographer, Kelvin Thomas, worked with LAST students for a new storm drain stencil project video. Love A Sea Turtle’s “Turtle Team” of student volunteers led and participated in the storm drain stenciling project, promoted the project through awareness initiatives and table and poster displays, and took active roles as mentors for other youth in the community. At the completion of the grant cycle, representatives from the LAST presented the project report to the City's EAC during the June 2018 meeting. No applications were received for the 2018 EAC Grant. Funds were instead redirected to promotional items for the other educational booths and events.

Throughout the year we distribute fact sheets and brochures at presentations; special events; such as Citizen’s Academy, City Commissions and to the general public in order to educate on specific concerns. The City continues to work towards the development of further stormwater related brochures covering such topics as stormwater requirements for new development and redevelopment projects, maintenance practices by the City on open and closed storm drainage systems, street acceptance, commercial car wash operations and illicit discharge issues associated with restaurants.
