7.1.2 Target Audience
Roxboro residents, school children, local businesses (including gas station owners
and landscaping companies) and industry, are targeted because these groups
have the most impact on stormwater pollution prevention.
7.1.3 Target Pollutant Sources
The education program targets 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 are also targeted.
The education program address's the proper use and disposal of typical household
chemicals, garden chemicals, and used motor oil.
7.1.4 Outreach Program
School programs, printed materials are distributed via mail and public events, and
participation in state cleanup programs will be used to reach the target audience.
CWEP stormwater materials are given to every new customer at City Hall. CWEP
also runs a digital media campaign that covers Internet, TV and Radio services in
the City. By using these methods, the education program reaches the majority of
residents of Roxboro, as well as those that do business here. 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.
7.1.5 Decision Process
The formation of the stormwater 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 were 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.

7.3.2 Storm Sewer System Map
The storm sewer system will be mapped and field verified 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 added to the City's
GIS database. The map will be updated as needed during subsequent
maintenance operations.
7.3.3 Regulatory Mechanism
The stormwater ordinance to include illicit detection, right of entry, and prohibition
of certain non-stormwater discharges.
7.3.4 Enforcement:
There are provisions in the 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.

CITY OF ROXBORO
7.3.6 Non Stormwater Discharges
Currently there are no known non-stormwater discharges that are a significant
contributor to the IVIS4. 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 BIVIP's listed in the Public
Education section of this plan. These educational BIVIP'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 BIVIP'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 STORMWA TER RUNOFF CONTROL
The City of Roxboro 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.

7.5.2 Stormwater Management Options
The existing land usage ordinance includes a post -construction stormwater runoff
management program for new development and redevelopment projects that
disturb greater than, or equal to, one acre. This includes projects of less than one
acre that are a part of a larger common plan of development or sale that discharges
into the MS4. All such projects shall be required to apply for locally issued
construction permit coverage under one of the following stormwater management
options:
7.5.2.1 Low Density Projects
Projects shall be permitted as low density if the project meets the following:
(1) No more than 2 dwelling units per acre or 24 percent built -upon area
(BUA) for all residential and non-residential development;
(11) Stormwater runoff from the development shall be transported from
the development by vegetated conveyances to the maximum
extent practicable:
(III)AII BUA shall be at a minimum of 30 feet landward of all perennial
and intermittent surface waters. For the purpose of this Rule, a
surface water shall be present if the feature is approximately
shown on either the most recent version of the soil survey map
prepared by the Natural Resources Conservation Service of the
United States Department of Agriculture or the most recent
version of the 1:24,000 scale (7.5 minute) quadrangle
topographic maps prepared by the United States Geologic
Survey (USGS). An exception to this requirement may be
allowed when surface waters are not present in accordance with
the provisions of 15A NCAC 213 .0233 (3)(a); and
(IV) The permit shall require recorded deed restrictions and protective
covenants to ensure that development activities maintain the
development consistent with the approved project plans.
7.5.2.2 High Density Projects
Projects exceeding the low density threshold (established above in low
density section) shall implement stormwater control measures that:
(1) Control and treat the difference in stormwater runoff volume leaving
the project site between the pre and post development conditions
for the 1 year 24 hour storm. Runoff volume drawdown time shall

(11) All structural stormwater treatment systems used to meet the
requirements of the program shall be designed to have an 85%
average annual removal for Total Suspended Solids:
(III)General Engineering Design Criteria for all projects shall be in
accordance with 15A NCAC 2H .1 008(c);
(IV) All BUA shall be at a minimum of 30 feet landward of all perennial
and intermittent surface waters. For the purpose of this Rule, a
surface water shall be present if the feature is approximately
shown on either the most recent version of the soil survey map
prepared by the Natural Resources Conservation Service of the
United States Department of Agriculture or the most recent
version of the 1:24,000 scale (7.5 minute) quadrangle
topographic maps prepared by the United States Geologic
Survey (USGS). An exception to this requirement may be
allowed when surface waters are not present in accordance with
the provisions of 15A NCAC 2B .0233 (3)(a); and
(V) The permit shall require recorded deed restrictions and protective
covenants to ensure that development activities maintain the
development consistent with the approved project plans;
7.5.3 Non -Structural BMP's
The receiving streams in the City's watershed are classified as Nutrient Sensitive
Waters; therefore the amended ordinance shall also ensure that the best
management practice for reducing nutrient loading is implemented. In addition, a
nutrient application (both inorganic fertilizer and organic nutrients) management
program shall be developed and included in the stormwater management program.
7.5.4 Structural BMPs
Standards and policies will be developed that ensure structural BMPs will be in
conformance with the state's Stormwater Management Design Manual.
7.5.5 Regulatory Mechanism
The City will annually assess existing ordinances, policies, programs and studies
that address storm water runoff quality. In addition to assessing these existing
documents and programs, the City will provide opportunities to the public to
participate in the development of the program. .
7.5.6 Operation and Maintenance
The existing land usage ordinance will be amended to address the long-term
operation and maintenance of post -construction controls. The amended ordinance
Page 23

COMPREHENSIVE STORMWATER MANAGEMENT PROGRAM REPORT
CITY OF ROXBORO
will include guidelines for delegating routine and non -routine maintenance
responsibilities to ensure access for inspections, and providing a mechanism for
enforcement.
7.5.7 Decision Process
The post construction stormwater management program shall ensure that controls
are in place that will prevent or minimize water quality impacts from new
development and redevelopment projects. These controls should include an
amended ordinance to address post -construction runoff control from new
development and redevelopment projects and ensure adequate long-term
operation and maintenance of BMPs.
7.5.8 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.

7.6.2 Affected Operations
The City of Roxboro operates a municipal building, 3 fire stations, a police
department, public works department, water treatment plant, wastewater treatment
plant, and 11 sewer pump stations. Operations at all of the affected operations will
be reviewed during the permit cycle.
7.6.3 Training
Training materials will be maintained on pollution prevention for public facilities,
using similar materials as will be used in the public outreach program. All
employees will be educated annually 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, 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. This
training will be in conjunction with the training requirements of the future Spill
Prevention, Control, and Countermeasures plan.
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
The Preventive maintenance program will be continued and will include routine
inspections of catch basins, storm water detention areas, and water quality
treatment systems. A similar program will be maintained for vehicles, equipment,
and material storage areas in the maintenance yard. Inspections will ensure all
equipment and material storage containers are in good condition. Any problems
or issues that may have an impact on stormwater quality will be noted and
corrective action taken. Vehicle washing and fueling operations will be inspected
annually to ensure that they are in good working order and that they minimize
exposure of stormwater to chemicals, fuels, and other liquids. Schedules and
procedures will be established for the inspections, and an organized record -
keeping system will be implemented to schedule and document inspections.

7.6.5 Vehicular Operations
All vehicles, equipment, and associated material are stored in covered facilities.
The vehicle and equipment washing operation currently employs a sediment
removal device within the wash bay. The City also uses a vacuum street sweeper
to regularly clean City roads and parking lots. The collected debris is temporarily
stored in an uncovered area at the waste water treatment plant, before transfer to
the landfill. As part of the stormwater management plan, other pollution reduction
measures (such as installation of a oil/water separator for the wash bay or covering
the temporary storage area) will be evaluated and implemented.
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. Garbage,
yard waste, and heavy garbage collection are collected by the City. 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 Roxboro 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 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.
