National Emission Standards for Hazardous Air Pollutants: Manufacture of Amino/Phenolic Resins Risk and Technology Review Reconsideration

This action finalizes amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Manufacture of Amino/Phenolic Resins (APR). These final amendments are in response to petitions for reconsideration regarding the APR NESHAP rule revisions that were promulgated on October 8, 2014. In this action, we are revising the maximum achievable control technology (MACT) standard for continuous process vents (CPVs) at existing affected sources. In addition, we are extending the compliance date for CPVs at existing sources. We also are revising the requirements for storage vessels at new and existing sources during periods when an emission control system used to control vents on fixed roof storage vessels is undergoing planned routine maintenance. To improve the clarity of the APR NESHAP, we are also finalizing five minor technical rule corrections. In this action, we have not reopened any other aspects of the October 2014 final amendments to the NESHAP for the Manufacture of APR, including other issues raised in petitions for reconsideration of the October 2014 rule.
