National Emission Standards for Hazardous Air Pollutants: Chemical Manufacturing Area Sources Technology Review

摘要

The Environmental Protection Agency (EPA) is finalizing amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Chemical Manufacturing Area Source (CMAS) categories pursuant to a technology review under Clean Air Act (CAA) section 112(d)(6). Specifically, the EPA is finalizing new leak detection and repair (LDAR) requirements for equipment leaks and heat exchange systems in organic hazardous air pollutant (HAP) service. In addition, the EPA is taking final action to add standards for pressure relief devices (PRDs) and pressure vessels; require electronic reporting for notification of compliance status (NOCS), performance test reports, and periodic reports; and require continuous performance testing of non-flare air pollution control devices (APCD). The EPA is not finalizing the proposed area source category for chemical manufacturing with ethylene oxide (EtO) or related standards at this time.
