Information for Facilities that are Required to Report

Is your facility required to submit a Tier II report?

If you are not sure, the following information will help assist you in making that determination.


The minimum requirement for reporting Hazardous Material inventory is: 

  • Extremely Hazardous Substance (EHS) = 500 pounds or the threshold planning quantity (TPQ), whichever is less. The amount of an EHS at a facility (both pure and in mixtures) must be aggregated for purposes of threshold determination. Include the EHS in a mixture if it makes up at least 1% of the mixture, or 0.1% if the EHS is a carcinogen. EHSs and their TPQs are listed in Appendix A

  • 10,000 pounds or more of a hazardous chemical or a quantity necessary referenced by the Threshold Planning Quantity of the chemical through the EPA "List of Lists";

  • Gasoline (all grades combined) at retail gas stations if all gasoline is stored in compliant underground storage tanks (UST) = 75,000 gallons. The term gasoline includes gasohol which is composed of at least 90% gasoline and up to 10% ethanol;
