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 Mebane, 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.

X X X X X Development Director COMPREHENSIVE STORMWATER MANAGEMENT PROGRAM REPORT CITY OF MEBANE Page 19 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 City 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 City 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 City, or receive approval for a revised schedule, the City will take enforcement action and the connection will be removed at the responsible party’s expense. COMPREHENSIVE STORMWATER MANAGEMENT PROGRAM REPORT CITY OF MEBANE Page 20 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 City 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 City ordinance to allow for greater enforcement and penalties. 7.4 CONSTRUCTION SITE STORMWATER RUNOFF CONTROL The City of Mebane will rely on the North Carolina State Erosion and Sediment Control Program and the Department of Water Resource’s general stormwater permit program for construction activities to meet the construction site stormwater runoff control requirement.

X City Engineer City Planner COMPREHENSIVE STORMWATER MANAGEMENT PROGRAM REPORT CITY OF MEBANE Page 22 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. 7.5.3 Non-Structural BMP’s The receiving streams in the City’s watershed are classified as Nutrient Sensitive Waters; therefore the post construction ordinance ensures that best management practices for reducing nutrient loading are implemented. 7.5.4 Structural BMPs The City has certified its BMP manual as equal to the NC DWQ BMP Manual. The City reviews structural BMP’s based on the NC DWQ BMP Manual and will continue to do so in the future. The City may investigate additional qualified BMP’s in the future. These additional techniques are to be evaluated based upon field testing and evaluation by the City’s Engineer. 7.5.5 Regulatory Mechanism The City’s Post-Construction Ordinance establishes the City’s ability to regulate new development for water quality compliance. 7.5.6 Operation and Maintenance The City’s Post-Construction Ordinance establishes the City’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 City will require annual submissions of BMP inspection reports and the City 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 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. COMPREHENSIVE STORMWATER MANAGEMENT PROGRAM REPORT CITY OF MEBANE Page 23 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.

The City’s Facilities O&M Plan for Reducing Stormwater Pollution Runoff from Municipal Operations report identified most of the City’s facilities as having minimal potential for stormwater pollution. The City’s Public Works Facilities, Wastewater Treatment Plant, and pump stations are high risk and are evaluated on a daily basis by City personnel as well as annually through the City’s facility O&M evaluations. 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 are educated on the need for controls to protect stormwater from exposure to potential pollutants. This training also serves 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. 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. COMPREHENSIVE STORMWATER MANAGEMENT PROGRAM REPORT CITY OF MEBANE Page 26 7.6.5 Vehicular Operations All vehicles, equipment, and associated material at both the Public Works and Parks & Rec. facilities are stored inside buildings. Washing of vehicles is performed in the wash bay at public works. Minor vehicle and equipment maintenance take place at these facilities. 7.6.6 Waste Disposal Debris and floatables collected from the MS4 are temporarily stored in an uncovered area at the maintenance facility before transfer to the landfill. The City of Mebane performs its own garbage, yard waste, and heavy trash collection. Recyclables collection is contracted out to a private company. Used oil from vehicle and equipment maintenance operations is stored onsite and periodically collected by a certified oil recycler. 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 City of Mebane would begin creating a Water Quality Recovery Plan (WQRP) 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 DEMLR 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.
