WASHINGTON—The Environmental Protection Agency is proposing an air emission regulation that could affect producers of flexible polyurethane foam. The regulation, to be presented in the Federal Register this month, will address emissions of hazardous air pollutants from the production of slabstock, molded and rebond flexible PU foam. The proposal would prohibit use of methylene chloride and other hazardous air pollutants as a mixhead flush, mold-release agents and pollutant-based adhesives at flexible molded foam facilities.
If approved, the regulation would require toluene diisocyanate and methylene chloride emissions to be reduced from storage tanks and equipment leaks, and would prohibit the use of pollutant-based cleaners.
Comments on the proposal will be accepted 60 days after it appears in the register. The proposal can be found online at http://www.epa.gov/fedrgstr/epa-air or by calling (919) 541-5742.
