Page 13 COMPREHENSIVE STORMWATER MANAGEMENT PROGRAM REPORT TOWN OF ELON 7.1.2 Target Audience Elon residents, school children, local businesses (including gas station owners and landscaping companies) and industry, will be targeted because these groups have the most impact on stormwater pollution prevention. 7.1.3 Target Pollutant Sources The education program will target total suspended solids and nutrient loading because turbidity, sedimentation, and nutrients are the pollutants of concern in downstream waters. In addition, floatables, trash, and debris will also be targeted. The education program will also address the proper use and disposal of typical household chemicals, garden chemicals, and used motor oil. 7.1.4 Outreach Program School programs, printed materials to be distributed via mail and public events, and participation in state cleanup programs will be used to reach the target audience. By using these methods, the education program will be expected to reach all residents of Elon, as well as those that do business here, over the course of the five year permit period. As a result of this outreach program, the target audience will be informed of the importance of reducing storm water pollution and ways they can incorporate pollution reduction in their daily lives. Direct Education was chosen over mass media due to availability of the cooperative stormwater education program, Stormwater Smart, and due to studies showing the effectiveness of direct education over mass media. 7.1.5 Decision Process The formation of the storm water public education and outreach program was based on the mechanisms currently in place, and their means and effectiveness of communicating and educating the public about the issues of stormwater pollution prevention. Each of the BMP's selected was judged to be an effective and economical tool for educating the general public and/or specific groups within the community, with a specific measurable goal with which to gauge its effectiveness. 7.1.6 Evaluation The education and outreach program will be evaluated based on how each individual BMP is meeting its measurable goal at the end of each reporting period. Changes will be considered for any BMPs that are not meeting the measurable goals. Page 14 COMPREHENSIVE STORMWATER MANAGEMENT PROGRAM REPORT TOWN OF ELON 7.2 PUBLIC INVOLVEMENT AND PARTICIPATION 7.2.1 BMP Summary Table BMP Measurable Goals YIR Y2R Y3R Y4R Y5R Responsible Position/Party Public Meeting A public meeting will be held annually to discuss the X X X X Town Planner implementation of the permit beginning in year 2. This Town Clerk meeting will provide the public with the opportunity to be involved with the stormwater program and will serve Town SEC as a better conduit for public input than the stormwater committee used previously. More meetings may be held if public involvement is substantial. Volunteer Stormwater Program The Town will promote various volunteer stormwater X X X X X Town SEC programs annually. These will include Big Sweep, Town Planner Adopt -A -Stream programs, and Storm Drain Stenciling. The number of participants will be reported annually. Helpline / Hotline All stormwater related calls will be forwarded to the X X X X X Town Planner Town Planner who will then distribute the information to other employees. Page 15 COMPREHENSIVE STORMWATER MANAGEMENT PROGRAM REPORT TOWN OF ELON 7.2.2 Target Audience The Town's stormwater committee will be discarded in favor of an annual public meeting. The public meetings will allow the public an opportunity to review the stormwater management program and will target all interested and affected members of the Elon community. Additional meetings may be held if public involvement is substantial. The Town's committee was ineffective in soliciting widespread public input. 7.2.3 Participation Program The public was originally involved in the development of the stormwater permit and management program through a public hearing in 2005. Public participation opportunities will be implemented throughout the life of the permit through the Volunteer Stormwater Programs and the Annual Public Meeting. 7.2.4 Decision Process A public meeting is necessary for public participation and input. The other BMPs were selected to give the public a choice of both active and passive participation roles. 7.2.5 Evaluation The Public Involvement and Participation program will be evaluated based on how each individual BMP is meeting its measurable goal at the end of each reporting period. Changes will be considered for any BMPs that are not meeting the measurable goals.

Page 17 COMPREHENSIVE STORMWATER MANAGEMENT PROGRAM REPORT TOWN OF ELON 7.3.2 Storm Sewer System Map Storm sewer system has been mapped and will be inspected during the course of normal maintenance operations by the public service department. The route of the system, locations of pipes, drainage ditches, and outfalls will be maintained on a paper map and/or electronic map. The map will be updated as needed during subsequent maintenance operations. 7.3.3 Regulatory Mechanism The Town has an Illicit Discharge Ordinance which allows for inspection, maintenance, and prohibits illicit discharges. 7.3.4 Enforcement: There are provisions in the amended ordinance for enforcement actions and penalties for dumping, spills, and willful illicit connection. 7.3.5 Detection and Elimination After the field screening is complete, the Town will take measures to identify and remove illegal discharges. Identifying illegal discharges may require a combination of office and field work. After the field screening, staff will consult the jurisdiction - wide information they have compiled to obtain information about the land uses, infrastructure, industries, potential sources and types of pollution that may exist in the drainage area of the outfall. After priority areas have been identified in the office, a systematic field investigation will be planned that minimizes the amount of resources required to identify the source. The following field methods may be used to identify and trace the source of illegal discharges: • Site Investigation • Dry weather flow observations • Smoke Testing/Dye Testing • Television Inspection The right of entry established in the ordinance will provide access for inspection if the origin of the discharge is in doubt. Once an illegal discharge is located and confirmed through field screening, staff will notify the responsible party verbally if possible and follow-up with written notification. If the responsible party does not comply with the removal schedule provided by the Town, or receive approval for a revised schedule, the Town will take enforcement action and the connection will be removed at the responsible party's expense. Page 18 COMPREHENSIVE STORMWATER MANAGEMENT PROGRAM REPORT TOWN OF ELON 7.3.6 Non Stormwater Discharges Currently there are no known non-stormwater discharges that are a significant contributor to the MS4. If any are identified in the future, they will be addressed at that time. 7.3.7 Outreach Town employees will be informed of the hazards associated with illegal discharges and improper disposal of waste as part of their general training requirements. These will be addressed in the Pollution Prevention/Good Housekeeping section of this plan, and will include training in hazardous material handling and disposal, as well as notices and signs posted in the appropriate areas. The general public will be educated through the BMP's listed in the Public Education section of this plan. These educational BMP's will include brochures, public service announcements, and business education and outreach programs. 7.3.8 Decision Process The formation of the storm water Illicit Discharge Detection and Elimination program was based primarily on regulatory mechanisms. The regulatory, educational, procedural BMP's selected were judged to be an effective means of detecting and eliminating illicit discharges. 7.3.9 Evaluation The effectiveness of the program will be gauged by the total number of illicit connections detected and removed each year and with public complaints. If the total number remains constant, or increases, changes will be made to the public education program and/or the Town ordinance to allow for greater enforcement and penalties. 7.4 CONSTRUCTION SITE STORMWATER RUNOFF CONTROL The Town of Elon will rely on the North Carolina State Erosion and Sediment Control Program and the Department of Water Quality's general stormwater permit program for construction activities to meet the construction site stormwater runoff control requirement.

Town SEC Page 20 COMPREHENSIVE STORMWATER MANAGEMENT PROGRAM REPORT TOWN OF ELON 7.5.2 Stormwater Management Options The existing land usage ordinance has a post -construction stormwater runoff management program for new development and redevelopment projects that disturb greater than, or equal to, one acre. This ordinance may be revised prior to the end of year 3 of the permit to incorporate Low Impact Development (LID) provisions and Nutrient Reduction limits as defined in the Jordan Lake Nutrient Reduction Strategy will be adopted within the timeline established by NC Session Laws and NC DWQ Regulations. 7.5.3 Non -Structural BMP's The receiving streams in the Town's watershed are classified as Nutrient Sensitive Waters; therefore the post construction ordinance ensures that best management practices for reducing nutrient loading are implemented. In addition, a nutrient application (both inorganic fertilizer and organic nutrients) management program has been developed and is included in the stormwater management program. 7.5.4 Structural BMPs The Town has certified its BMP manual as equal to the NC DWQ BMP Manual. The Town reviews structural BMP's based on the NC DWQ BMP Manual and will continue to do so in the future. The Town may investigate additional qualified BMP's in the future. These additional techniques are to be evaluated based upon field testing and evaluation by the Town's Engineer. 7.5.5 Regulatory Mechanism The Town's Post -Construction Ordinance establishes the Town's ability to regulate new development for water quality compliance. 7.5.6 Operation and Maintenance The Town's Post -Construction Ordinance establishes the Town's ability to regulate new development for water quality compliance. The ordinance includes guidelines for delegating routine and non -routine maintenance responsibilities to ensure access for inspections, and providing a mechanism for enforcement. The Town will require annual submissions of BMP inspection reports and the Town will inspect each BMP during each permit cycle. 7.5.7 Education An education process for developers and citizens about new development with respect to stormwater and water quality has been established and is ongoing. 7.5.8 Decision Process Page 21 COMPREHENSIVE STORMWATER MANAGEMENT PROGRAM REPORT TOWN OF ELON The post -construction stormwater management program ensures that controls are in place that will prevent or minimize water quality impacts from new development and redevelopment projects. These controls include post -construction ordinance to address post -construction runoff control from new development and redevelopment projects and ensure adequate long-term operation and maintenance of BMPs. Future revisions to this ordinance will be intended to enhance water quality. 7.5.9 Evaluation The post -construction site management for new and re -development activities program will be evaluated based on how each individual BMP is meeting its measurable goal at the end of each reporting period. Changes will be considered for any BMPs that are not meeting the measurable goals.

Page 23 COMPREHENSIVE STORMWATER MANAGEMENT PROGRAM REPORT TOWN OF ELON 7.6.2 Affected Operations The Town of Elon operates a municipal building that serves as a Town hall and fire station, a police station, a Public Works vehicle and equipment storage yard, and a maintenance facility for the Parks & Recreation Department. All vehicles, equipment, and materials at the storage yard and Park maintenance facility are stored in covered buildings. There are no floor drains in any of the buildings at these two facilities. 7.6.3 Training Training materials have been developed on pollution prevention for public facilities, using similar materials as will be used in the public outreach program. All employees will be educated on the need for controls to protect stormwater from exposure to potential pollutants. This training will also serve as the training requirement for public employees as specified in the outreach component of the Illicit Discharge section of this program. All public employees involved in vehicle, open space, or building maintenance operations will be provided training in BMPs, the processes and materials they are working with, safety hazards, practices for preventing discharges, and procedures for responding quickly and properly to toxic and hazardous material incidents. All public employees involved in stormwater drainage system maintenance will be specifically trained in the disposal of floatables, grit, sediment, and other pollutants removed from the system. Additional training, or certification, will be provided to employees that manage and apply chemicals for control of dust, pests, vermin, and weeds and/or to enhance the growth or condition of public urban landscape and recreation facilities. Training will target the safe and effective application, storage and disposal of chemicals used. 7.6.4 Maintenance and Inspections A preventive maintenance program has been developed that includes routine inspections of catch basins and other stormwater systems for the municipal building and vehicle storage yard. The objective of the inspections is to reduce pollutant loading from municipal sites. Inspections include noting any problems or issues that may have an impact on stormwater quality, and any corrective actions needed. Schedules, procedures, and a record -keeping system are used to schedule and document inspections. Page 24 COMPREHENSIVE STORMWATER MANAGEMENT PROGRAM REPORT TOWN OF ELON 7.6.5 Vehicular Operations All vehicles, equipment, and associated material at both the Public Works and Parks & Rec. facilities are stored inside buildings. The Public Works vehicles (pickup and dump trucks) are currently washed outside, with the untreated wash water discharging into a nearby drainage ditch. Washing of these vehicles at another location has been investigated but is non -cost effective and pollution runoff is minimized by runoff not going across impervious areas and not going directly into surface waters. Minor vehicle and equipment maintenance take place at these facilities. 7.6.6 Waste Disposal Garbage, recyclables, and heavy trash collection are contracted out to private companies. 7.6.7 Flood Management Projects Future flood management projects will be reviewed from a water quality standpoint. 7.6.8 Decision Process The most effective and practical BMPs for minimizing stormwater pollution were selected for this program. 7.6.9 Evaluation The pollution prevention/good housekeeping for municipal operations program will be evaluated based on how each individual BMP is meeting its measurable goal at the end of each reporting period. Changes will be considered for any BMPs that are not meeting the measurable goals.

A TMDL with no WLA will not require a Water Quality Recovery Plan, but rather the need to evaluate existing strategies and if any can be tailored or expanded to improve the water quality in the TMDL watershed. 7.7.3 Establishing a Water Quality Recovery Plan Based on the above schedule the Town of Elon would begin creating a Water Quality Recovery Plan (WARP) within 12 months of establishment of the TMDL, would have evaluated existing measures within 24 months, developed a monitoring plan within 36 months, and would be implementing or have planned for implementation within 48 months. The WQRP would be submitted and approved by NC DWQ and EPA. 7.7.4 Decision Process TMDL planning and implementation will be done in an effort to improve water quality and with the approval of NC DWQ staff. 7.7.5 Evaluation Progress toward restoring water quality standards will be difficult to determine and most evaluation tools will be based upon programs rather than through water quality monitoring or water quality improvements. While the goal of a WQRP is to improve water quality standards, the NPDES MS4 permit obligation is to reduce non -point source pollutant loading to the maximum extent practicable (MEP). The MS4 is not required to meet water quality standards. Evaluation of successful techniques will be evaluated over time, probably multiple permit cycles. Page 27
