Hazardous and regulated material spills released into the environment must be reported to a manager or supervisor to initiate reporting and cleanup activities by properly trained responders. Installation heads should maintain and reference any facility-specific spill, emergency response, or contingency planning documents. Additionally, Postal Service™ policy requires the completion of PS Form 8187, Hazardous and Regulated Substance Release Notification, to internally report the release of these materials.
Common reportable materials used at USPS® sites that may prompt additional reporting requirements to the United States Environmental Protection Agency, state, or local regulatory agencies, depending on the quantity released into the environment include the following:
In general, spills to the environment must be reported if they reach:
n Stormwater drains or ponds
n Dry wells or catch basins
