Section 313 of the Emergency Planning and Community Right to Know Act of 1986 requires that a facility prepare and submit to the U.S. EPA Toxic Chemical Release Inventory Reporting Form R for each listed chemical it uses, manufactures, or processes in an amount greater than the applicable threshold. The applicable threshold depends on the nature of the chemical and the type of activity. Facilities must report the quantities of both routine and accidental releases of listed toxic chemicals, the maximum amount of the listed toxic chemical onsite during the calendar year, and the amount contained in wastes transferred offsite or treated onsite. Verdant Environmental has prepared the SARA 313 report for a company operating several petroleum refineries for more than 10 years.
