McDOWELL COUNTY HAZARDOUS MATERIALS EMERGENCY PLAN
APPENDIX 6 TO HMEP
TECHNIQUES FOR SPILL CONTAINMENT AND CLEAN-UP
A.
An
important area of any hazardous materials incident is the ability to contain
the product within a defined area and then restore the area to its prior
condition. This plan, however, cannot adequately cover the various forms in
which a hazardous materials emergency may appear.
A.
The
Incident Commander (IC) has the responsibility of evaluating the health hazard
of the contaminants to the clean-up workers. He/she will request assistance, as
necessary, from health officials, the facility, transporter, or manufacturer.
After evaluation of the hazard, the Incident Commander must determine the most
appropriate method with which to proceed.
B.
There
are three (3) basic methods in which to approach containment. These methods are
not the only appropriate solutions, and, as always, the individual incident
will dictate what approaches should be followed.
1.
Diking
a.
Where
a leak is emanating from a vehicle, dikes should be placed around both sides of
the vehicle rather than just in the area of the leak. Further, the location of
the dikes in relation to the vehicle must be determined after the hazards to
workers have been evaluated. For example, if it appears that the leak or spill
is likely to explode, then the dikes should be placed much further away than if
there is no likelihood of explosion. Along with diking, it is vital that
precautions are taken to keep the contaminants from entering a water system.
Such precautions should include covering manholes and sewers with several
layers of plastic, sand, soda ash, and/or oil dry.
2.
Discharge
a.
Suppression
options include creating a water fog or covering the discharge with foam to
prevent the formation of a toxic cloud. Steps should be taken to plug the leak.
3.
Allow
the Product to Continue to Burn
a.
Burning
should specifically be allowed if the material consists of hydrocarbons and if
the material is located either in a pipe or in a cylinder under pressure. Often
in these instances, the best action will be no action, except for monitoring
the fire to keep it from spreading.
A.
Emergency
responders at minor emergency situations should use whatever techniques are
appropriate for the situation. For example, these techniques should include but
not be limited to the following:
1.
There
are guidelines set forth by the Occupational Safety and Health Administration
(OSHA), which governs hazardous waste operations and emergency response
activities.
2.
Flushing
the area with water.
3.
Preparing
dikes.
4.
Gathering
the contaminants into DOT-permitted drums for proper disposal.
5.
If
the situation grows beyond the emergency responder’s capabilities, private
contractors should be contacted.
6.
Following
the removal of all hazardous materials from the clean-up, the affected area
must be returned to its original condition when feasible. Only materials
equivalent to those removed should be used.
7.
After
all liquids, waste residues, and surrounding contaminated soil have been
removed from the site, sampling should be performed for confirmation of
complete waste removal. If any residual contamination remains and it is
determined that additional removal is not feasible, a site closure plan should
be written for review by the applicable state or federal agencies. Such a plan
must document that the contaminants left in the soil will not adversely impact
any environmental media (ground water, surface water, or atmosphere), and that
direct contact through dermal exposure, inhalation, or ingestion will not
result in a threat to human health or the environment. The agencies can then
determine what additional monitoring will be necessary, such as ground water
sampling, so that these sites can be left “clean”.
8.
Transportation
assistance and/or escort services for containment and clean-up purposes will be
available when the situation arises through local, county, and state law
enforcement agencies.
9.
The
person or group that requests, leases, borrows, etc. equipment will be
responsible for returning that equipment in full working order to the owner.
Where a private contractor is involved, that contractor will be entirely
responsible for his/her own equipment used in the emergency response
activities.
A.
The
Regional Hazmat Response Team will be responsible for containment of the
hazardous material, if activated and involved.
B.
Clean-up
of a minor hazardous materials incident will be the Incident Commander’s
responsibility to accomplish or oversee, depending upon whether the product
owner can be ascertained.
C.
Clean-up
of a major hazardous materials incident will the Incident Commander’s (in
conjunction with the WVDEP) responsibility to oversee.
D.
Local
fire services are not prepared or equipped to contain or clean-up a large
release. Private contractors will be needed to assist or conduct the activity.
The party responsible for causing the spill and/or the owner of the material
will be encouraged to arrange clean-up in a timely, professional manner, in
accordance with all applicable rules and regulations, as required by law.
