EPA SARA 313 Reporting (form R & A)

Superfund Amendments and Re-authorization Act (SARA) of 1986 and the Emergency Planning and Community Right to Know Act (EPCRA) as Title III of SARA regulation require facilities that fall under OSHA 29 CFR 1910.1200 to report (Form R) their Toxic Release Inventory on annual basis if they meet or exceed applicable reporting thresholds for certain chemicals.

Gasoline and diesel fuel are subject to SARA reporting as they are subject to OSHA’s MSDS requirements under 29 CFR 1910.1200. Therefore, if a Gas Station has 75,000 gallons of gasoline or 100,000 gallons of diesel fuel in underground storage tanks, or 10,000 pounds of either in an above-ground storage tank or more on-site at any one time in the previous calendar year they are subject to Tier II reporting. Bulk facilities must continue to report using the 10,000-pound threshold.
