National Emission Standards for Hazardous Air Pollutants: Paper and Other Web Coating Residual Risk and Technology Review (52 page(s), in English)

成员国:美国

通报日期:2019-09-27

内容概述:

Proposed rule - The U.S. Environmental Protection Agency (EPA) is conducting the residual risk and technology review (RTR) of the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Paper and Other Web Coating (POWC) source category that is required under the Clean Air Act (CAA). We are proposing to find the risks due to emissions of air toxics to be acceptable from this source category and that the current NESHAP provides an ample margin of safety to protect public health. Further, we identified no new cost-effective controls under the technology review that would achieve significant further emissions reductions, and, thus, are proposing to find that no revisions are necessary based on developments in practices, processes, or control technologies. In addition to performing the RTR, we are proposing certain amendments to the POWC NESHAP. Specifically, the EPA is proposing to add a compliance demonstration equation that accounts for retained volatiles in the web coating; to amend provisions addressing periods of startup, shutdown, and malfunction (SSM); to add repeat testing and electronic reporting requirements; and to make technical and editorial changes. The EPA is proposing these amendments to improve the effectiveness of the NESHAP.
