Permit Compliance System. Contains data on more than 75,000 water-discharge permits.
Comprehensive Environmental Response, Compensation & Liability Information. Consists of Superfund data on hazardous waste site assessment and remediation.
Toxic Release Inventory System (TRIS). Features data on the release and transfer of more than 300 toxic chemicals and compounds by medium of release (air, water, underground injection, land disposal and off-site), reported by over 33,000 submitters.

The Right-to-Know Network
The Right-to-Know Network RTK NET was started in 1989 in support of the Emergency Planning and Community Right to Know Act (EPCRA), which mandated public access to the Toxic Release Inventory. Its databases provide and alternate access to the EPA information above, and more.
