The Emergency Planning and Community-Right-to-Know Act (EPCRA) was enacted by Congress to assist local communities in protecting public health by requiring facilities to file an annual EPCRA Tier II Report, identifying hazardous chemical inventories maintained at the facility. Submitting Tier II Reports allows the local emergency personnel to be aware of the chemicals that are present within facilities in their jurisdiction, and prepare for and respond to chemical emergencies.
The annual federal deadline for submitting Tier II Reports is March 1st (more to come on
this deadline). Facilities are required to report any chemicals, which are included within the OSHA Hazard Communication Standard (29 CFR 1910.1200). A list of EHSs and their TPQs can be found at 40 CFR 355, Appendix A. The EPA has compiled a “List of Lists” which provides a consolidated list of chemicals that are subject to EPCRA Tier II reporting along with their Threshold Planning Quantities (TPQ). The TPQ is the amount of chemical kept on-site above which you must file a Tier II. It is important to note that ammonia has a Tier II reporting threshold of 500 pounds.
Some states require that Tier II forms be submitted electronically, while other states may require hard copy submittals. Still, others require both digital and printed submissions.
