Check the regulations for exact or specific language, exceptions, and optional “No Exposure” Exemptions.
“No Exposure” means all industrial materials and activities are protected by a storm resistant shelter to prevent exposure to rain, snow, snow-melt, and/or runoff.
Drums, barrels, tanks and similar containers that are tightly sealed do not automatically require storm resistant shelters provided that those containers are not deteriorated and do not leak. This is basically for fresh containers.
“Sealed” means banded or otherwise secured and without operational taps or valves. Opened containers are going to be affected.
This does not mitigate or reduce EPA spill containment regulations, but rather enhances it.
