Suggested protocols, cont'd.=20
Storage areas=20
* Provide storage tank piping located below product level with a
shut-off valve at the tank; ideally, this valve should be an automatic =
shear
valve with the shut-off located inside the tank.=20
* Provide barriers such as posts or guardrails, where tanks are
exposed, to prevent collision damage with vehicles.=20
* Provide secure storage to prevent vandalism-caused contamination.=20
* Place tight-fitting lids on all containers.=20
* Enclose or cover the containers where they are stored.=20
* Raise the containers off the ground by use of pallet or similar
method, with provisions for spill control.=20
* Contain the material in such a manner that if the container leaks or
spills, the contents will not discharge, flow or be washed into the =
storm
drainage system, surface waters or groundwater.=20
* Place drip pans or absorbent materials beneath all mounted container
taps, and at all potential drip and spill locations during filling and
unloading of containers. Any collected liquids or soiled absorbent =
materials
must be reused/recycled or properly disposed.=20
* Ensure that any underground or aboveground storage tanks are designed
and managed in accordance with applicable regulations, identified as a
potential pollution source and have secondary containment such as a berm =
or
dike with an impervious surface.
Inspection=20
Provide regular inspections:=20
* Inspect storage areas regularly for leaks or spills.=20
* Conduct routine inspections and check for external corrosion of
material containers. Also check for structural failure, spills and =
overfills
due to operator error or failure of piping system.=20
* Check for leaks or spills during pumping of liquids or gases from
truck or rail car to a storage facility or vice versa.=20
* Visually inspect new tank or container installations for loose
fittings, poor welding and improper or poorly fitted gaskets.=20
* Inspect tank foundations, connections, coatings, tank walls and
piping system. Look for corrosion, leaks, cracks, scratches and other
physical damage that may weaken the tank or container system.=20
* Replace containers that are leaking, corroded or otherwise
deteriorating with ones in good condition. If the liquid chemicals are
corrosive, containers made of compatible materials must be used instead =
of
metal drums.=20
* New or secondary containers must be labeled with the product name and
hazards.
Next week, the final part of these tips will address training, spill =
response
and other considerations.
