EPA is taking direct final action to approve revisions to the Maricopa County Environmental Services Department (MCESD) portion of the Arizona State Implementation Plan (SIP), and the Placer County Air Pollution Control District (PCAPCD) and South Coast Air Quality Management District (SCAQMD) portions of the California SIP. These revisions concern volatile organic compound (VOC) emissions from Pharmaceutical, Cosmetic and Vitamin Manufacturing Operations, Fiberboard Manufacturing, and Hydrogen Plant Process Vents.
