Abstract:
This action requests comments and information on n-propyl bromide (nPB) under the U.S. Environmental Protection Agency's (EPA) Significant New Alternatives Policy (SNAP) program. SNAP implements section 612 of the amended Clean Air Act of 1990 (CAAA), which requires EPA to evaluate substitutes for ozone depleting substances (ODSs) to reduce overall risk to human health and the environment. Through these evaluations, SNAP generates lists of acceptable and unacceptable substitutes for each of the major industrial use sectors. The intended effect of the SNAP program is to expedite movement away from ozone depleting compounds while avoiding a shift into substitutes posing other environmental or health problems. Through this Advance Notice of Proposed Rulemaking (ANPR), the Agency hopes to receive information as part of the development of effective regulatory options on the listing of nPB as acceptable or unacceptable for the various submitted end-uses under SNAP. This action notifies the public of the availability of information regarding nPB and the Agency hopes that this action will provide the public an opportunity to provide input at an early stage in the decision-making process. This notice does not constitute a final, or even preliminary, decision by the Agency. Based on information collected as part of this ANPR, EPA intends to propose a future determination regarding the acceptability or unacceptability of nPB as a substitute for class I and class II ozone depleting substances and, if acceptable, an occupational exposure limit (OEL) for nPB. This limit would be designed to protect worker safety until the Occupational Safety and Health Administration (OSHA) sets its own standards under Public Law 91-596. However, until a final determination is made, users of nPB should exercise caution in the manufacture, handling, and disposal of this chemical. EPA has received petitions under CAAA Section 612(d) to add nPB to the list of acceptable alternatives for class I and class II ozone depleting substances in the solvent sector for general metals, precision, and electronics cleaning, as well as in aerosol and adhesive applications.
