The EPA is seeking comments on its plan to amend the standards that control emissions of toxic air pollutants from petroleum refineries. The current rules were issued in 1995. EPA’s current proposal provides options for the control of air emissions from storage tanks as well as revisions to the maximum achievable control technology work practice standards for cooling towers. Its goal is to reduce 2,250 tons of air toxics emitted each year as well as cutting 14,600 tons of volatile organic compounds emissions. The proposal also revises the proposed MACT work practice standards for cooling towers, revises the definition of a leak, and revises the requirements for leak detection and repair programs. Public comment on the proposal will be accepted for 45 days after its publication in the Federal Register.
