Toxic Release Inventory

The Toxic Release Inventory must be forwarded annually on July 1st to the Ohio EPA and the USEPA. This inventory is a mass balance for chemicals that enter and leave manufacturing facilities each year. For more information about this program please visit the Ohio EPA TRI Website.

Risk Management Plans

Many facilities storing significant quantities of extremely hazardous substances are required to complete Risk Management Plans (RMPs). The chemical accident prevention regulations require full updates and submission of the RMPs at least once every five years or when there is a significant change in inventory.
