The Emergency Response Planning provisions require that state and local authorities develop chemical emergency preparedness and response capabilities through better coordination and planning with local businesses.

Extremely Hazardous Substances (EHS) Threshold Planning Quantities (TPQs) are determined by the EPA based on their potential to cause significant health effects in a single exposure. The Emergency Planning Notification requirement involves chemicals listed on the EHS list (see 40 CFR Part 355, Appendices A and B).

Any facility that has any of the listed chemicals at or above its TPQ must notify the HSERC and LEPC within 60 days after they first receive a shipment or produce the substance on site.
