North Carolina’s number one water quality problem is stormwater runoff pollution. As stormwater flows across impervious surfaces, it picks up various pollutants, such as oil & grease, excess nutrients, bacteria and sediment. Polluted stormwater flows down our storm drains and ditches where it is discharged, untreated, into our streams, rivers, and lakes. Stormwater runoff pollution causes adverse impacts to aquatic ecosystems, poses human health risks, and can greatly increase the cost of treating our drinking water. Program Background In 1972, the National Pollutant Discharge Elimination System (NPDES) program was established under the authority of the Federal Clean Water Act. Phase I of the NPDES Stormwater program was established in 1990. It required NPDES permit coverage for municipalities with populations of 100,000 or more. Phase II of the NPDES Stormwater program was signed into law in December 1999. The Phase II program extended permit coverage to smaller (< 100,000 pop.) c ommunities and public entities that own or operate a municipal separate storm sewer system (MS4). It required these smaller communities to develop a stormwater program and obtain an NPDES permit for stormwater discharges. In North Carolina, the Department of Environment and Natural Resources, Division of Water Quality (NCDWQ) administers the NPDES Stormwater program. NCDWQ issued the Town of Ayden’s (Town) initial Phase II permit, on December 1, 2005. The permit required the Town to develop, implement, and enforce a stormwater program designed to reduce the discharge of pollutants from the MS4 to the maximum extent practicable. The program was implemented in phases over the last five years. Pursuant to the permit the stormwater program included the following six minimum measures or best management practices (BMPs): 1. Public education and outreach; 2. Public involvement/participation; 3. Illicit discharge detection and elimination; 4. Construction site stormwater runoff controls; 5. Post-construction site runoff controls for new development and redevelopment; 6. Pollution prevention and good housekeeping for municipal operations.

Storm Sewer System Information 1.1 Population Served Estimated population served........................4,9431 1.2 Growth Rate Estimated growth rate..................................7.5%2 1.3 Jurisdictional Area Town Limits..................................................3.27 sq. mi ETJ Only....................................................14.63 sq. mi. Total Planning Jurisdiction………………...17.90 sq. mi. 1.4 MS4 Conveyance System Much of the Town’s stormwater conveyance system is in excess of 50 years old, thus it consists of a variety of materials and components. These range from typical curb and gutter systems conveyed by concrete, terra cotta, ductile iron and corrugated galvanized pipes to simple sheet flow. The predominate conveyance components include grass lined swales and vegetated drainage ditches with various pipes and culverts. There are also very few detention facilities within the Town’s jurisdiction; with all of these being located on private property. Stormwater conveyance system components are periodically inspected to ensure proper function. Additionally, visual inspections are performed during significant rain events. The North Carolina Department of Transportation (NCDOT) maintains systems within their public road rights-of-way. Systems located on private property, including detention facilities and other structural and nonstructural BMP’s, are maintained by the owner. The Town, as part of its stormwater program, performs mechanical street sweeping and leaf/debris removal on a weekly basis on all streets within its jurisdiction. Additionally, stormwater piping is mechanically cleaned by means of a high pressure water jet vacuum assisted truck. After cleaning, the stormwater piping is videoed with a crawling camera which transmits video to DVD. This work assists in identifying possible pipe failures/fractures. 1 July 2008 Town Population Estimate Data from North Carolina Office of Budget and Management, http://www.osbm.state.nc.us/. 2 Percentage increase from 2000 to 2008 (source North Carolina Office of Budget and Management).

Stormwater Management Program Plan The following sections describe the Town’s Stormwater Management Program and measurable goals for each BMP. While the six BMPs are not expected to change over the life of this Stormwater Management Plan, measurable goals may be modified, removed, or new goals added. Changes may be necessary to meet permit renewal requirements, changes in resources, or to be more effective in reducing impacts to the MS4. Modifications to these goals will be documented within the required annual report. 7.1 Public Education and Outreach The Town’s stormwater public education and outreach program includes dissemination of educational materials at festivals and special events, the development and distribution of a stormwater newsletter to all town utility customers, and the provision of a Stormwater Management Program Page on the Town’s Website. Target Pollutant Sources Land use within the Town’s jurisdiction is composed primarily of residential, commercial, and agricultural uses. Target pollutant sources from these land uses include: Sediment – Sediment can adversely impact waterways and aquatic environments. Due to recent drought cycles, maintaining vegetative cover has been an issue. For new construction, erosion control is necessary to keep sediment on site. Litter/Yard Waste – Litter and yard waste can block stormwater conveyances. As litter and yard waste decompose it introduces chemicals and additional nutrients into the storm system. General Household and Landscape Chemicals – These include fertilizers, pesticides, automotive chemicals, and detergents and can cause significant impacts to aquatic environments. Target Audience Two primary target audiences have been identified, local citizens and business owners. Local citizens will be targeted via their residences, churches, schools, and other civic groups. Business owners, particularly developments with high impervious surface ratios, will be targeted. Measurable Goals . A. Develop and Distribute Materials Develop educational materials or modify/utilize existing materials available from other agencies. Distribute educational materials through educational programs, local events (such as Downtown Day and the Ayden Collard Festival) and placement of informational flyers at Town Hall (4144 West Avenue) and the Town Operations Center (4061 East Avenue). B. Stormwater Related Newsletter Publish a Town Newsletter related the Town’s Stormwater Management Program and general water quality issues quarterly.

Measurable Goals A. Storm Sewer System Map The Town of Ayden maintains a Geographic Information System (GIS) database that includes detailed geospatial information related to the Town’s storm sewer conveyance system. The database also includes geospatial information related to drainage areas, receiving streams, land use, zoning, floodplain data, and other pertinent data. This information is updated periodically. Pursuant to the Town of Ayden’s current permit, components of their MS4 were mapped using Global Positioning System (GPS) technology and are included in the GIS. The Town will update the GIS Stormwater Layer to reflect changes to the MS4 as necessary. This may include updating stormwater system components for new development, repairs, and maintenance, in addition to updating stream data based on surface water identification requests. Mapping updates of the MS4 is solely the Town’s responsibility. B. Regulatory Mechanism Article VII of the Town’s Phase II Stormwater Ordinance provides the regulatory mechanism for addressing illicit discharges and connections to the Town’s MS4 System. The Town will continue to maintain this regulatory mechanism for the duration of this Plan. C. Procedures for Illicit Discharge Detection and Elimination In an effort to identify and eliminate illicit discharges into the MS4, the Town will investigate citizen complaints; identify at least one new priority area for detection and elimination annually; and conduct dry weather inspections in priority area(s). D. Staff Training The Town will provide appropriate employees with information related to the hazards associated with illegal discharges and improper disposal of waste. The Town will further explore the feasibility of partnering with other regional Town of Ayden Comprehensive Stormwater Management Plan ~ 14 ~ Phase II Communities to conduct at least one training session for Town employees related to this topic. E. Public Outreach The Town will provide area businesses and the general public with information related to the hazards associated with illegal discharges and improper disposal of waste. This information will be distributed as part of the Public Education and Outreach Program component of this Plan via the previously described Stormwater Related Newsletter and Stormwater Page on the Town’s Website. F. Local Stream Monitoring Evaluate the need for additional stream sampling/monitoring. Identify possible partnerships for collaborative sampling/monitoring efforts. Evaluation The Town’s Public Illicit Discharge Detection and Elimination Program will be evaluated by assessing progress towards each measurable goal listed above. Generally, inspection and complaint information will be logged and tracked. Assessments will be made toward completion of the goals listed above. Progress will be reported each year in the annual report to the state. 7.4 Construction-Site Stormwater Runoff Control Pitt County implements and enforces construction site stormwater runoff control for the Town of Ayden through its Soil Erosion and Sedimentation Control Program. Pitt County has local delegated authority from the state to implement such a Program. Measurable Goals A. Regulatory Mechanism Pitt County administers the Pitt County Soil Erosion and Sedimentation Control Ordinance within the town’s planning jurisdiction. Authority to do so is provided by Inter-Local Agreement. B. Plan Review Pitt County reviews and approves Soil Erosion and Sedimentation Control Plans for proposed new development projects within the Town’s jurisdiction to ensure compliance with the Pitt County Soil Erosion and Sedimentation Control Ordinance. C. Inspections Pitt County inspects permitted construction sites within the Town’s jurisdiction to ensure compliance with approved Soil Erosion and Sedimentation Control Plans. As needed, they request corrective actions, issue Notice of Violations and Stop Work Orders as outlined in the Ordinance. Town of Ayden Comprehensive Stormwater Management Plan ~ 15 ~ Evaluation Pitt County maintains a database and inspection reports on each permitted construction site. Information regarding number of sites, acreage of disturbance, compliance, notice of violations, and enforcement actions are tracked and will be included in the annual report to the state for sites within the Town’s jurisdiction. 7.5 Post-Construction Stormwater Management in New Development and Redevelopment The Town’s Post-Construction Stormwater Program includes four primary components: new development review, stormwater BMP inspection, education and outreach, and retro-fit opportunities. The Town is responsible for the implementation and enforcement of its Phase II Stormwater Ordinance. Regulatory Mechanism On September 8, 2008, the Town of Ayden Governing Board adopted the Town of Ayden Phase II Stormwater Ordinance which provides the regulatory mechanism for post-construction stormwater controls in the town’s jurisdiction. Post-Construction Stormwater Requirements The Town of Ayden utilizes both structural and non-structural BMPs to treat and control post-construction stormwater. Non-structural BMPs include stream buffers, flood hazard zone protection, and landscaping requirements. Structural stormwater BMPs include those listed in the NCDWQ Stormwater BMP Manual. Through its Phase II Stormwater Ordinance, the Town requires structural BMPs to have a signed operations and maintenance agreement and certification by a licensed engineer that the BMPs have been properly constructed. These measures are in place to ensure proper operation of the BMP. Specific post-construction stormwater requirements for new development are outlined below. For projects that individually, or cumulatively, disturb more than one-acre there are two options; low-density and high-density. A project is a low-density project if it has no more than two dwelling units per acre for residential development and no more than twenty-four (24) percent built-upon area (BUA) for non-residential development. Low-density development requirements include: Use vegetative conveyances; Minimum stream buffers (30-feet); Reduce nutrient loading (i.e. Meet Neuse River Basin Rules); Must have an operation and maintenance agreement and restrictive covenants for structural BMPs. A project is a high-density project if it exceeds the low-density threshold for dwelling units per acre and/or built-upon area. Town of Ayden Comprehensive Stormwater Management Plan ~ 16 ~ High-density development requirements include: 85% total suspended solids reduction; Control/treat the first 1-inch of rainfall; Discharge the storage volume at a rate equal to or less than the predevelopment discharge rate for the one (1) year, twenty-four (24) hour storm; Drawdown between 48 and 120 hours; Reduce nutrient loading (i.e. Meet Neuse River Basin Rules); Must have an operation and maintenance agreement and restrictive covenants for structural BMPs.; Minimum stream buffers (30-feet). Other Related Policies, Practices, Regulations In addition to the specific post-construction stormwater requirements listed above, the Town of Ayden employs other policies, practices and regulations that help to protect the water quality of its receiving waters. Measures are currently in place that help to protect natural resources, protect open space, preserve trees, regulate redevelopment and street design. During the Comprehensive Plan development process, the Town is evaluating additional measures to minimize water quality impacts associated with future development activities. Measurable Goals A. New Development Review Review and approve proposed new development projects to ensure compliance with the Town’s Phase II Stormwater Ordinance requirements. B. BMP Inspections Inspect new structural stormwater BMPs at the time the project is complete to ensure compliance with approved plans. Map new BMPs using GPS/GIS technology. Review required annual inspection reports submitted by the BMP owner. Conduct follow-up inspections as warranted and provide inspection reports to owner outlining follow up actions. Issue notice of violations if warranted. C. Education/Outreach This portion of the Post-Construction Stormwater Management Program is part of the overall education/outreach component described in Sections 7.1 and 7.2 herein. This primarily includes providing information to businesses, homeowner associations and other stormwater BMP owners about maintenance and inspection requirements. D. Retro-fit Opportunities Identify at least one new possible stormwater retro-fit location annually. Evaluate sites already identified based on land availability, willing ownership, potential for pollution reductions, and other pertinent variables. Rank these sites and evaluate grant availability and/or other funding sources to implement retro-fits. Identify potential partnerships to develop and fund retro-fit projects. Town of Ayden Comprehensive Stormwater Management Plan ~ 17 ~ Evaluation Electronic records of each BMP site approved through the Town’s Phase II Stormwater Ordinance, including inspection records, shall be maintained by the Town. Information regarding the number of plans reviewed, BMP inspections and other pertinent information will be included in the annual report to the state for development within the Town’s jurisdiction. 7.6 Pollution Prevention / Good Houskeeping for Municipal Operations The Town’s Pollution Prevention/Good Housekeeping Program includes four primary components: evaluate Town operations, corrective action, employee training, and public awareness. Affected Town Operations The following facilities are owned by the Town and are included in Pollution Prevention/Good Housekeeping Program: 1. Town Hall; 2. Town Operations Center; 3. Old Town Hall; 4. Community Building; 5. Arts and Recreation Community Center; 6. Veteran’s Park; 7. J.J. Brown Park; 8. Town Library 9. Water Distribution System; 10.

Training The Town will provide appropriate employees with information related to preventing and reducing pollutant runoff from municipal operations. The Town will further explore the feasibility of partnering with other regional Phase II Communities to conduct at least one training session for Town employees related to this topic. This training may be combined with training related to the hazards associated with illegal discharges into the MS4 and improper disposal of waste. B. Public Awareness Provide information to users of public facilities regarding efforts and measures implemented, instructions for proper use of facilities, and penalties for failure to comply. C. Maintenance and Inspections Ensure implementation of the following: Town of Ayden Comprehensive Stormwater Management Plan ~ 18 ~ The Town will perform street sweeping on all town streets on a weekly basis. The Town will utilize a vehicle wash area wherein all wastewater is drained to the sanitary sewer, not the storm sewer system. The Town will investigate and, where appropriate and feasible, implement an Integrated Pest Management Program wherein the prevention and management of pests including insects, weeds and plant disease is addressed by a minimally toxic method. The Town will continue a systematic schedule of high-pressure cleaning the piped portions of the town’s storm sewer system. The Town will continue to limit the use of salt for safety in extreme cold temperature events. When salt is required to provide for the public safety, it is no more than a 1/3 salt - 2/3 sand mixture that is limited to sidewalks and intersections. Town of Ayden Comprehensive Stormwater Management Plan ~ 19 ~ ANNUAL REPORTING In order to help evaluate the effectiveness of the Town’s NPDES Phase II Stormwater Program, NCDWQ requires the submittal of an annual report.
