The Postal Service is reminding facilities with aboveground storage tanks that monthly visual inspections of the containers are required.
Aboveground storage tanks, or ASTs, are used to store oil, antifreeze, heating oil and other hazardous chemicals.
USPS could be held liable if chemicals inside the ASTs — which are usually made of fiberglass, plastic or metal — leak into the environment.
Monthly inspections help confirm the ASTs are secure.
The Aboveground Storage Tank Management Environmental Compliance Bulletin, available on the Environmental Affairs Blue page, has more information.
Employees who have questions should consult their region’s designated USPS environmental specialist.
