Emergency Planning and Community Right-To-Know Act (EPCRA) was created to protect communities from the health and environmental hazards associated with hazardous chemicals. Under Section 312 of the Act, regulated industries must file an annual Tier II report with the SERC, LEPC, and local fire department for hazardous and/or extremely hazardous substances stored, used, or manufactured on site for more than a 24 hour period at any time during the previous calendar year. The deadline for filing a Tier II report for the previous year is March 1st.
Reporting Thresholds: Minimum thresholds have been established for Tier II reporting under Title III, Section 312. The federally established reporting thresholds are as follows:
For Extremely Hazardous Substances (EHSs) designated under section 302 of Title III, the reporting threshold is 500 pounds (or 227 kg.) or the threshold planning quantity (TPQ), whichever of those two amounts is lower. The Environmental Protection Agency’s (EPA) List of Lists should be consulted for the actual reporting quantities.
For all other hazardous substances for which facilities are required to have or prepare a Safety Data Sheet (SDS), the minimum reporting threshold is 10,000 pounds (or 4,540 kg.). Liquids must be converted from gallons to pounds for Tier II reporting.
