Tier II Reporting

The Massachusetts Statewide Emergency Response Commission (SERC) was established to promote chemical emergency preparedness and prevention through collaboration and planning. The Emergency Planning and Community Right-to-Know Act (EPCRA) requires facilities to maintain material safety data sheets for any hazardous chemical used or stored in the workplace.

Facilities covered by the reporting requirements of EPCRA must submit annual Tier II reports to their Emergency Planning Committee, Local Fire Department, and the State Emergency Response Commission.
