Determine EPCRA Section 312 Tier II reporting obligations for hazardous chemicals.
If any chemical is determined to be reportable, ensure you collect the following information for your Tier II report documentation (as per 40 CFR 370.42):
Facility managers can seamlessly determine emergency planning notification requirements using this EPCRA Tier II threshold calculator. By evaluating stored chemical inventories against EPA thresholds for Extremely Hazardous Substances (EHS) and standard hazardous chemicals, you avoid missing critical annual reporting deadlines. Accurately identifying reportable quantities protects your business from compliance fines while providing local emergency responders with crucial safety data.
Under EPCRA regulations, any chemical that requires an OSHA Safety Data Sheet (SDS) under the Hazard Communication Standard is considered a hazardous chemical and is potentially subject to Tier II reporting if thresholds are met.
The general reporting threshold for most standard hazardous chemicals (those not classified as EHS) is 10,000 pounds present at the facility at any one time during the calendar year.
For an EHS, a facility must submit a Tier II report if the maximum amount present at any one time equals or exceeds its chemical-specific Threshold Planning Quantity (TPQ) or 500 pounds, whichever value is lower.
Yes. You must calculate the weight of the hazardous chemical component within the mixture, or alternatively report the entire weight of the mixture if the specific concentration of the hazardous component is unknown.
