7.1.2 Target Audience
Mebane 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 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.

7.2.2 Target Audience
The City will hold an annual public meeting rather than trying to solicit stormwater
committee members. 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 Mebane community. Additional meetings may be held if
public involvement is substantial.
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.

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.
Page 19

COMPREHENSIVE STORMWATER MANAGEMENT PROGRAM REPORT
CITY OF MEBANE
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.

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
7.6.2 Affected Operations
The City of Mebane has a City Hall, three fire stations, a police station, a public works facility, a waste water treatment
plant, an Arts and Community Center, a parks and recreation department, several parks and 15 sewer pump stations. 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.

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.

7.7.2 Determination of TMDL's
A TMDL on a receiving water with a stormwater Waste Load Allocation (WLA)
will trigger the need for compliance with this section of the CSWMP. 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 (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 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.
