(1) A general location map (USGS quadrangle map, or appropriately drafted equivalent
map), showing the facility's location in relation to transportation routes and surface
waters, and the name of the receiving water(s) to which the stormwater outfall(s)
discharges. If the discharge is to a municipal separate storm sewer system, the name
of the municipality and the ultimate receiving waters, and accurate latitude and
longitude of the point(s) of discharge must be shown.
(2) A narrative description of storage practices, loading and unloading activities, outdoor
process areas, dust or particulate generating or control processes, and waste disposal
practices.
(3)
A site map (or series of maps) drawn to scale with the distance legend indicating
location of industrial activities (including storage of materials, disposal areas, process
areas, and loading and unloading areas), drainage structures, drainage areas for each
outfall and activities occurring in the drainage area, building locations and impervious
surfaces, the percentage of each drainage area that is impervious. For each outfall, a
narrative description of the potential pollutants which could be expected to be present
in the regulated stormwater discharge.
(4) A list of significant spills or leaks of pollutants that have occurred at the facility during
the 3 previous years and any corrective actions taken to mitigate spill impacts.

prevent materials exposure to stormwater. In areas where elimination of exposure is

Permit NC0003719
not practicable, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(2) A schedule to provide secondary containment for bulk storage of liquid materials,
storage of Section 313 of Title III of the Superfund Amendments and Reauthorization
Act (SARA) water priority chemicals, or storage of hazardous materials to prevent leaks
and spills from contaminating stormwater runoff. If the secondary containment
devices are connected directly to stormwater conveyance systems, the connection shall
be controlled by manually activated valves or other similar devices [which shall be
secured with a locking mechanism] and any stormwater that accumulates in the
containment area shall be at a minimum visually observed prior to release of the
accumulated stormwater. Accumulated stormwater shall be released if found to be
uncontaminated. Records documenting the individual making the observation, the
description of the accumulated stormwater and the date and time of the release shall
be kept for a period of five years.
(3)
A narrative description of Best Management Practices (BMPs) to be considered such
as, but not limited to, oil and grease separation, debris control, vegetative filter strips,
infiltration and stonnwater detention or retention, where necessary. The need for
structural BMPs shall be based on the assessment of potential of sources contributing
significant quantities of pollutants to stormwater discharges and data collected
through monitoring of stormwater discharges.
(4) Inspection schedules of stormwater conveyances and controls and measures to be
taken to limit or prevent erosion associated with the stormwater systems.
c. Spill Prevention and Response Plan: The Spill Prevention and Response Plan shall
incorporate a risk assessment of potential pollutant sources based on a materials inventory of

program shall be developed. The program shall document schedules of inspections and
maintenance activities of stormwater control systems, plant equipment and systems.
Inspection of material handling areas and regular cleaning schedules of these areas shall be
incorporated into the program.
e. Training schedules shall be developed and training provided at a minimum on an annual
basis on proper spill response and cleanup procedures and preventative maintenance
activities for all personnel involved in any of the facility's operations that have the potential to
contarniratP stormwater runoff Facility personnel (or team) responsible for implementing the
training shall be identified in the plan.
f. The Stormwater Pollution Prevention Plan shall identify a specific position(s) responsible for
the overall coordination, development, implementation, and revision to the Plan.
Responsibilities for all components of the Plan shall be documented and position(s)
assignments provided.
g•
