The Emergency Planning & Community Right-to-Know Act (EPCRA) requires facilities storing any substance for which a material safety data sheet (MSDS) is required by OSHA and in quantities exceeding the Threshold Planning Quantity (specified for Extremely Hazardous Substance or 10,000 pounds for all other substances) to report these substances to the state, Local Emergency Planning Committees (LEPC's) and fire departments. The SC State Emergency Response Commission requires an annual submission of a Tier II report due March 1 from qualifying facilities.
