Postal Service facilities that store certain quantities of hazardous chemicals must complete and submit the Emergency Planning and Community Right-to-Know Act (EPCRA) Tier II form by March 1 each year.
Reporting requirements apply to any location that stores threshold quantities of EPCRA-regulated chemicals, such as sulfuric acid in lead-acid and gel cell batteries; gasoline; diesel fuel; heating oil; propane; and ice melt/anti-skid products.
In most cases, the federal reporting threshold is 10,000 pounds.
USPS facilities that exceed this threshold must complete and submit an EPCRA Tier II form to notify state and local emergency response agencies about the potential hazards on site.
The Tier II Reporting Environmental Compliance Bulletin, available on the Environmental Affairs Blue page, has more information.
