Chemical Used in Adhesives, Dry Cleaning to be Listed as Hazardous Air Pollutant

chemicalsIn a move that could affect manufacturers and dry cleaners, the EPA is moving forward with efforts to add the chemical n-Propyl Bromide (nPB) to a list of hazardous air pollutants in the Clean Air Act.

The agency today published a draft notice of its intent to regulate nPB, also known as 1-bromopropane (1-BP), under the Clean Air Act.

The chemical is used in vapor degreasing, aerosol adhesives, foam cushions and dry cleaning. According to the EPA, it’s a possible human carcinogen.

The chemical is also one of the first 10 substances the EPA in November said it would evaluate for potential risks to human health and the environment under the updated Toxic Substances Control Act.

“Based on the EPA’s evaluation of the petitioners’ showing concerning potential hazards, emissions, and atmospheric dispersion modeling that provided estimates of ambient concentrations of nPB, the EPA has determined that there is adequate evidence to support a determination that emissions and ambient concentrations of nPB may reasonably be anticipated to cause adverse health effects,” the agency said in the notice, published in the Federal Register and now open to public comment until March 10.

Last year, the Halogenated Solvents Industry Alliance, a solvents industry group, and the New York State Department of Environmental Conservation, threatened to sue the EPA for not listing nPB as a hazardous air pollutant.

The Halogenated Solvents Industry Alliance has said the chemical causes peripheral and central nervous system damage, and these effects have been seen in exposed workers.
