Storm Water Pollution Prevention Plan
|
|
|
The Storm Water Pollution Prevention Plan is
considered to be the most important requirement of the General
Permit. Each facility covered by this permit is required to
develop a plan, tailored to the specific conditions and with
the primary goal of controlling pollutants that may be discharged
into storm water runoff.
Components of the Plan: Each storm water plan must
include a site map and a description of the measures and controls
that will be used to prevent and/or minimize pollution of
storm water. The site description must include:
- Topographic Map: Maps must extend one-fourth mile
beyond the property line, showing the facility, surface
water bodies, wells, seepage pits, infiltration ponds, storm
water discharge points;
- A Site Map: Maps should include all outfalls and
storm water discharges, drainage areas of each storm water
outfall, structural storm water pollution control measures
(i.e. retention ponds, vegetation swales, sediment traps),
name of receiving water/separate municipal storm sewer system,
locations of exposed significant materials, location of
past spills/leaks, location of high risk/waste-generating
areas and activities;
- Narrative Description: Include the activities (industrial)
occurring at the facility, significant materials that are
treated, stored or disposed of in a manner to allow exposure
with storm water;
Materials, equipment and vehicle maintenance practices
employed to minimize contact of significant materials
to storm water;
Existing structural and non-structural control measures
employed to reduce pollutants in storm water discharges;
Industrial storm water discharge treatment facilities;
Methods of on-site storage and disposal of significant
materials;
- Material Inventory: A list of all materials, used,
stored, or produced on site with emphasis on those materials
that are exposed to storm water and have the potential of
polluting storm water runoff;
- List All Significant Spills or Leaks: Include all
spills and leaks that occurred during the past three years;
- Storm Water Management Controls: Include all methods
that will be utilized to control significant pollutants
in storm water runoff;
Identify storm water pollution prevention plan personnel
who will be responsible for developing, implementing and
revising the plan;
Procedures for the inspection and maintenance of storm
water conveyance system devices;
Good housekeeping policies and procedures;
Identify areas where significant spills may occur that
would affect storm water discharges, as well as procedures
for handling such events;
- Storm Water Management Practices: List all measures
to remove significant pollutants from the storm water (i.e.
containment devices, oil-grease separators, debris and sediment
controls, waste chemical disposal);
- Sediment and Erosion Prevention: Identify topographic
areas that have a high potential for erosion of soil and
the methods to be employed to reduce such erosion;
- Employee Training: Periodic training of all employees
at all levels of responsibility should be conducted in the
storm water pollution prevention plan. Topics should include
spill response, materials/equipment handling procedures,
and good housekeeping strategies;
- Inspection Procedures: Qualified plant personnel
should conduct periodic inspections, documenting such inspections
and any corrective action to be initiated:
- Non-Storm Water Discharges: A qualified plant employee
should conduct a visual inspection of storm water to assure
that non-storm water discharges are not entering the storm
water (i.e. oil sheen). In addition, an inspection of procedures/equipment
for the discharge on non-storm water should be conducted
when appropriate. Laboratory testing is not required but
should be conducted if reason exists to believe that significant
pollutants are present in the storm water discharges;
- Annual Inspection: An annual inspection is required
that includes a review of the storm water pollution prevention
plan, as well as the facility to assure all measures and
controls are operating properly. The annual report should
be submitted to the Agency as outlined in this permit;
- Other Program Requirements: The plan shall include
a description and records for additional federal and/or
local programs that may affect storm water discharges (i.e.
Spill Prevention Control and Countermeasures-SPCC);
- Signature Requirements: The signature of the person
responsible for the preparation of the initial plan and
all subsequent amendments to the plan should be included.
