Revisions to Standards of Performance for New Stationary Sources, National Emission Standards for Hazardous Air Pollutants, and National Emission Standards for Hazardous Air Pollutants for Source Categories
This action promulgates revisions to the General Provisions for Standards of Performance for New Stationary Sources, for National Emission Standards for Hazardous Air Pollutants, and for National Emission Standards for Hazardous Air Pollutants for Source Categories to allow for extensions to the deadline imposed for source owners and operators to conduct an initial or subsequent performance test required by applicable regulations. The General Provisions do not currently provide for extensions of the deadlines for conducting performance tests.
