New Compliance Options Added to MACT Standards for Petroleum Refinery Process Units

摘要

In a February 9, 2005 direct final rule (70 FR 6930-6973), EPA revised the maximum achievable control technology (MACT) standards for certain process units at petroleum refineries. The 40 CFR Part 63, Sub-part UUU MACT standards regulate emissions from fluidized catalytic cracking units (FCCUs), catalytic reforming units (CRUs), and sulfur recovery units (SRUs) at petroleum refineries. In addition, the MACT standards require owners/operators to implement work practice standards intended to limit hazardous air pollutant (HAP) emissions from bypass lines that can divert a vent stream away from a control device.
