The Community Right-to-Know provisions help increase the public's knowledge and access to information on chemicals at individual facilities, their uses, and releases into the environment.
States and communities, working with facilities, can use the information to improve chemical safety and protect public health and the environment.
Facilities must submit an annual inventory of these chemicals by March 1 of each year to their State Emergency Response Commission (SERC), Local Emergency Planning Committee (LEPC), and local fire department. The information submitted by facilities is made available to the public.
Any facility that is required to maintain Safety Data Sheets (SDS) and Material Safety Data Sheets (MSDS) under the Occupational Safety and Health Administration (OSHA) regulations for hazardous chemicals stored or used in the work place.
Facilities with chemicals in quantities that equal or exceed the following thresholds must report:
For Extremely Hazardous Substances (EHS): either 500 pounds or the Threshold Planning Quantity (TPQ), whichever is lower. The TPQ of an EHS can be found on the EPA’s Consolidated List of Lists.
For gasoline (all grades combined) at a retail gas station: the threshold level is 75,000 gallons (or approximately 283,900 liters), if the tank(s) was stored entirely underground and was in compliance at all times during the preceding calendar year with all applicable Underground Storage Tank (UST) requirements at 40 CFR part 280 or requirements of the State UST program approved by the Agency under 40 CFR part 281.
For diesel fuel (all grades combined) at a retail gas station: the threshold level is 100,000 gallons (or approximately 378,500 liters), if the tank(s) was stored entirely underground and the tank(s) was in compliance at all times during the preceding calendar year with all applicable UST requirements at 40 CFR part 280 or requirements of the State UST program approved by the Agency under 40 CFR part 281.
For all other hazardous chemicals: the threshold level is 10,000 pounds.
These documents are watermarked because facilities can no longer use them to report. However, they are still available for facilities to familiarize themselves on the type of information collected on the Tier II report.
