Storm  Water
Management  Fact  Sheet
Spill  Prevention  Planning
DESCRIPTION

Spill prevention is prudent both economically and
environmentally, because spills increase operating
costs and lower productivity.  An important tool in
preventing spills is a Spill Prevention Plan.  A Spill
Prevention   Plan  specifies  materials  handling
procedures and storage requirements and identifies
spill cleanup procedures for areas and processes in
which spills  may potentially occur.   The  plan
standardizes  process  operating  procedures and
employee training in an effort to minimize accidental
pollutant releases that could contaminate storm
water runoff.

Spill prevention should be part of a comprehensive
Best Management Practice  program to prevent
runoff contamination. This program should also
include storm water contamination assessment, flow
diversion,   record keeping,  internal  reporting,
employee training, and preventive maintenance.

Typically, most businesses and public agencies that
generate  hazardous  waste and/or  produce,
transport, or store petroleum products are required
by State and federal law to prepare spill control and
cleanup plans. Therefore, a  Spill Prevention and
Response Plan may have already been developed as
a  result   of  other  environmental  regulatory
requirements. Existing plans should be re-evaluated
and revised to address storm water management
issues.

APPLICABILITY

A Spill Prevention Plan is applicable to facilities that
transport, transfer, and/or store hazardous materials,
petroleum  products,   or  fertilizers  that  can
                      contaminate storm water runoff. An important part
                      of an effective Spill Prevention Plan is establishing
                      a method for quick notification of the appropriate
                      emergency response teams in the event of a spill. In
                      some plants, each area or process  may have a
                      separate team leader and/or response team. Figure
                      1 illustrates a sample spill prevention team roster
                      that can help  in quick identification of Spill
                      Prevention team leaders and their responsibilities.

                      ADVANTAGES AND DISADVANTAGES

                      The advantages of an effective Spill Prevention Plan
                      include reducing  storm water contamination and
                      maintaining the water quality of the receiving water.
                      Spill Prevention  Plans are often good ways of
                      standardizing procedures and employee  training to
                      decrease the likelihood of spills.

                      Spill Prevention Planning can be limited by the
                      following:

                      •     Lack of employee motivation to  implement
                            the plan.

                      •     Lack   of  commitment  from   senior
                            management.

                      •     Key  individuals identified in  the  Spill
                            Prevention Plan may not be properly trained
                            in the areas of spill prevention, response,
                            and cleanup.

                      KEY PROGRAM COMPONENTS

                      Before preparing a Spill Prevention Plan, a facility
                      should do the following:

-------
Once these tasks have  been accomplished,  the
facility should prepare its Spill Prevention Plan. The
plan should include:

•      A description of the facility, including the
       owner's name and address, the nature of the
       facility activity,  and the general  types of
       chemicals used in the facility.

•      A  site  plan  showing  the locations  of
       chemical  storage  areas,  storm  drains,
       tributary  drainage  areas  with  drainage
       arrows,  all surface water bodies on or next
       to the site, and any devices to stop spills
       from leaving the site (i.e., collection basins).
       Spill prevention devices should also have a
       description written  on the map.  Table  1
       contains a list of features that should be
       indicated on the site map.

•      Notification procedures to be used in the
       event of a spill. These should include phone
       numbers of key personnel and appropriate
       regulatory agencies, such as local Pollution
       Control  Agencies  and the local  Sewer
       Authority.

•      Specific  instructions  regarding  cleanup
       procedures.

•      A single designated  person who has overall
       responsibility  for spill  response.    Key
       personnel should be trained in the use of this
       plan, and all employees should have basic
       knowledge of spill control procedures.

A summary of the plan should be written and posted
at appropriate points in the building (i.e., meeting
rooms,  cafeteria,  and  areas with a  high  spill
potential).  The summary should identify the spill
cleanup coordinators, location of cleanup kits, and
phone numbers  of regulatory  agencies  to be
contacted in the event of a spill.

Implementing the Spill  Prevention  Plan  should
include the following:

•      Spill cleanups should begin immediately.
       No  emulsifier or dispersant should be used.
•      In  fueling  areas,  absorbent  should be
       packaged in small bags for convenient use
       and small drums should be  available for
       storage. Absorbent materials  should not be
       washed down the floor drain or into the
       storm sewer.

•      Emergency  spill containment and  cleanup
       kits should  be located at the facility site.
       The  contents   of   the  kit  should  be
       appropriate  to the type and  quantities of
       chemical or  goods stored at the facility.

Some  structural  methods  to  consider  when
developing a Spill Prevention Plan include:

•      Containment diking—Containment dikes
       are temporary  or  permanent  earth or
       concrete berms or retaining walls  that are
       designed to hold spills. Diking can be used
       at  any industrial  facility,   but  is  most
       common for  controlling  large spills or
       releases from liquid  storage and  transfer
       areas.  Diking can provide  one of the best
       protective   measures   against   the
       contamination of storm water  because it
       surrounds the area  of concern and  keeps
       spilled materials separated from the  storm
       water outside of the diked area.

•      Curbing—Similar to containment diking, a
       curb is a barrier that  surrounds an area of
       concern. Unlike diking, curbing is unable to
       contain  large   spills  and   is  usually
       implemented  on   a  small-scale   basis.
       However,  curbing  is common at  many
       facilities and in small areas where liquids are
       handled and transferred.

Collection basins—Collection basins are permanent
structures in  which large  spills or  contaminated
storm water is contained and stored before  cleanup
or treatment.  Collection basins are designed to
receive spills, leaks, etc., and to prevent pollutants
from being released into the environment.  Unlike
containment dikes, collection basins can receive and
contain  materials from many locations across a
facility.

In  addition   to  preventing  the  release of  the
substance to surface waters, any spilled substances
must be cleaned up and disposed  to protect plant
personnel from potential health and fire hazards.
Methods of cleanup,  recovery,  treatment,   or
disposal include:

•      Physical. Physical methods for the cleanup
       of dry chemicals include the use of brooms,
       shovels, sweepers, or plows.
       Mechanical.  Mechanical methods include
       the use of vacuum cleaning systems and
       pumps.

       Chemical.  Chemical  cleanups  of material
       can be achieved with the use of sorbents,
       gels, and foams.  Sorbents  are compounds
       that  immobilize  materials   by  surface
       absorption or adsorption in the sorbentbulk.
       Gelling agents interact  with the  spilled

-------
       chemical(s) by concentrating and congealing
       to  form a rigid or viscous material  more
       conducive to a mechanical cleanup. Foams
       are mixtures of air and aqueous solutions of
       proteins  and  surfactant-based   foaming
       agents. The primary purpose of foams is to
       reduce the vapor concentration above the
       spill surface, thereby controlling the rate of
       evaporation.

IMPLEMENTATION

Past experience has shown that the biggest obstacle
to  an  effective  Spill  Prevention  Plan  is  its
implementation. Qualitatively, implementation of a
well  prepared  Spill  Prevention  Plan  should
significantly decrease contamination of storm water
runoff.

A facility Spill Prevention Plan should be reviewed
at least annually and following any spills to evaluate
the Spill Prevention Plan's level of success and how
it  can be  improved.  The plan should  also be
reviewed when a new material is introduced to any
of the facility's processes.

COSTS

If a facility already has a Spill Control and Cleanup
Plan in place, modification to address storm water
contamination concerns will require minimal cost.
If a facility will be developing a Spill Prevention
Plan for the first time, the initial cost will depend on
the type of material at the facility, the facility size,
and other related parameters.  Costs for structural
containment devices will also need to be identified
for each facility.
