SUMMARY: EPA is taking final action for four national emission standards for hazardous air pollutants (NESHAP) that regulate 12 industrial source categories evaluated in our risk and technology review. The four NESHAP include: National Emissions Standards for Group I Polymers and Resins (Butyl Rubber Production, Epichlorohydrin Elastomers Production, Ethylene Propylene Rubber Production, Hypalon\TM\ Production, Neoprene Production, Nitrile Butadiene Rubber Production, Polybutadiene Rubber Production, Polysulfide Rubber Production, and Styrene Butadiene Rubber and Latex Production); Marine Tank Vessel Loading Operations; Pharmaceuticals Production; and The Printing and Publishing Industry.
For some source categories, EPA is finalizing our decisions concerning the residual risk and technology reviews. For the Marine Tank Vessel Loading Operations NESHAP and the Group I Polymers and Resins NESHAP, EPA is finalizing emission standards to address certain emission sources not previously regulated under the NESHAP. EPA is also finalizing changes to the Pharmaceuticals Production NESHAP to correct an editorial error. For each of the four NESHAP, EPA is finalizing revisions to the regulatory provisions related to emissions during periods of startup, shutdown, and malfunction and promulgating provisions addressing electronic submission of emission test results.
DATES: This final action is effective on April 21, 2011.
