2017-17514: National Emission Standards for Hazardous Air Pollutants: Manufacture of Amino/Phenolic Resins

Summary

On October 8, 2014, the Environmental Protection Agency (EPA) finalized amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Manufacture of Amino/Phenolic Resins (APR). Subsequently, the EPA received three petitions for reconsideration of the final rule. The EPA is reconsidering and requesting public comment on issues related to the maximum achievable control technology (MACT) standards for continuous process vents (CPVs) at existing affected sources. The EPA is proposing to revise the MACT standard for back-end CPVs at existing affected sources based on hazardous air pollutant (HAP) emissions test data for back-end CPVs at existing sources for this source category submitted by petitioners. The EPA is also soliciting comments regarding the need to revise the standard for front-end CPVs at existing sources, and to extend the compliance date for the proposed revised emission limit for back-end CPVs at existing sources. Additionally, the EPA is proposing requirements for storage vessels at new and existing sources during periods when an emission control system used to control vents on fixed roof tanks is undergoing planned routine maintenance. The EPA is seeking comments only on the four issues specifically addressed in this notice: proposed revised back-end CPV MACT standards for existing sources, whether the EPA should modify the front-end CPV MACT standards for existing sources, whether the EPA should extend the compliance date for the proposed revised back-end CPV MACT standards for existing sources, and the proposed work practice standards for storage vessels during planned routine maintenance of emission control systems. In this rulemaking, the EPA is not reopening or requesting comment on any other aspects of the 2014 final amendments to the NESHAP for the Manufacture of APR, including other issues raised in petitions for reconsideration of the 2014 rule. The EPA estimates this proposal, if finalized as proposed, would reduce compliance costs to this industry by $2.1 million per year, compared to a revised cost estimate of the MACT standard as amended in 2014.
