Excerpt from EPRCA - EPA finalized several changes to the Emergency Planning (Section 302), Emergency Release Notification (Section 304) and Hazardous Chemical Reporting (Sections 311 and 312) regulations that were proposed on June 8, 1998 (63 FR 31268). These changes include clarification on how to report hazardous chemicals in mixtures, and changes to Tier I and Tier II forms. Additionally, the rules now use a question and answer format. Facilities subject to EPCRA reporting, State Emergency Response Commissions (SERCs), Local Emergency Planning Committees (LEPCs) and fire departments should become familiar with the new regulation.

This final rule is effective on March 26, 2009.
