Section 112(d) of the Clean Air Act requires EPA to set emission standards for hazardous air pollutants emitted by sources in certain specified source categories and subcategories. EPA recently published final maximum achievable control technology (MACT) requirements for hazardous air emissions from major sources in the Brick and Structural Clay Products (BSCP) and Clay Ceramic Manufacturing (CCM) categories. It did so after the original BSCP and CCM MACTs were challenged by industry and environmental groups and were ultimately vacated and remanded to EPA by the D.C. Circuit in 2007.
Major provisions of the BSCP MACT include the following:
The CCM MACT includes significant new provisions:
The rule is effective on December 28, 2015, and existing BSCP and CCM facilities must comply with the applicable MACT by December 28, 2018.
