EPA Updates Refinery Standards to Require Fenceline Monitoring of Benzene Emissions

摘要

Petroleum refineries will be required to install monitors to measure fenceline concentrations of benzene, one of a series of new requirements established by the Environmental Protection Agency Sept. 29. The fenceline monitoring requirements are included in a final rule that updates national hazardous air pollution standards that apply to refineries, which also will be required to improve the efficiency of flares and comply with new emissions standards for delayed cokers. The EPA estimated the final rule (RIN 2060-AQ75), once fully implemented in 2018, will reduce emissions of benzene, xylene and other hazardous air pollutants by 5,200 tons per year. The agency also estimated the rule will cut emissions of volatile organic compounds, a precursor to the formation of ground-level ozone, by 50,000 tons per year.
