The EPA granted petitions from Halogenated Solvents Industry Alliance (HSIA) and New York State Department of Environmental Conservation (NYSDEC) to add n-propyl bromide, commonly known as 1-bromopropane (1-BP), to the Clean Air Act’s (CAA) list of hazardous air pollutants (HAPs). 1-BP is found in degreasers, cleaners, spray adhesives, automotive refrigerant flushes and lubricants. Nothing has been added to HAPs list since 1990.
Sound like good news, right? Well…under the Toxic Substances Control Act (TSCA), EPA noted last year that the chemical could pose “an unreasonable risk of injury to health” under certain conditions of use but did not find any unreasonable risk of injury to the environment. The risk evaluation is ongoing and is expected to be finalized this year.
One just has to wonder what exceptional circumstance will be required before any true regulatory activity would occur. Trump’s EPA gets to claim doing a good thing in both health and clearing up backlog but what comes next is what really matters.
