Chemical Storage

Chemicals should be stored in such a way to minimize stormwater contact. For example, chemicals should be stored in secondary containment (5 gallons or greater) and covered. If chemicals are stored inside a sealed building without secondary containment, the chemicals should be store far enough away from the door so that a spill would not be able to reach the outside environment.

Here are a few examples of chemical storage.

Improper Chemical Storage
