Economic Impact Analysis of the Clay Ceramics Manufacturing NESHAP: Final Rule

摘要

This report evaluates the economic impacts of pollution control requirements on ceramic floor and wall tile and sanitaryware manufacturing operations. The Clean Air Act (CAA) was designed to protect and enhance the quality of the nation's air resources and Section 112 of the CAA establishes the authority to control hazardous air pollutant (HAP) emissions. To reduce emissions of HAPs, the Agency establishes maximum achievable control technology (MACT) standards. The term 'MACT floor' refers to the minimum control technology on which MACT standards can be based. The MACT floor is set by the average emissions limitation achieved by the best performing 12 percent of sources in a category or subcategory when that category or subcategory contains at least 30 sources. For this NESHAP, the MACT floors for existing kilns at major sources in the clay ceramics source category require no control of HAP emissions; however new kilns at major sources in this source category are required to meet a MACT floor that entails some level of control. Since the proposed rule requires no control of existing sources, no costs will be incurred by existing sources.
