EPCRA & Tier II

EPCRA Section 311

Requires a facility to submit safety data sheets, or a list of the chemicals they cover, to state and local authorities.

Section 311 obliges a facility to give its State Emergency Response Commission, Local Emergency Planning Committee and fire department either the safety data sheets for its hazardous chemicals, or a list of those chemicals grouped by hazard category.

Most facilities submit the list rather than the sheets themselves. The submission is one-time for each chemical, with updates required when a new hazardous chemical arrives on site.

In practice Sections 311 and 312 are handled together, since both depend on the same underlying question of which chemicals are present above threshold.
