EPA Proposes New Emission Standards for Flexible Polyurethane Foam Production

Posted in on Tue, Nov 19, 2013

EPA has proposed amendments to the National Emissions Standards for Hazardous Air Pollutants for Flexible Polyurethane Foam Production to address the results of the residual risk and technology review.  In light of our review, we are proposing amendments that would prohibit the use of hazardous air pollutant-based auxiliary blowing agents for slabstock foam production facilities. In addition, the EPA is proposing amendments to correct and clarify regulatory provisions related to emissions during periods of startup, shutdown and malfunction; to add provisions for affirmative defense; to add requirements for reporting of performance testing through the Electronic Reporting Tool; to revise compliance dates for applicable proposed actions; to clarify the leak detection methods allowed for diisocyanate storage vessels at slabstock foam production facilities; and to revise the rule to add a schedule for delay of leak repairs for valves and connectors.  Comments are due December 4, 2013.
