Document Headings Document headings vary by document type but may contain the following: the agency or agencies that issued and signed a document the number of the CFR title and the number of each part the document amends, proposes to amend, or is directly related to the agency docket number / agency internal file number the RIN which identifies each regulatory action listed in the Unified Agenda of Federal Regulatory and Deregulatory Actions See the Document Drafting Handbook for more details. Environmental Protection Agency 40 CFR Part 82 [EPA-HQ-OAR-2002-0064; FRL-8316-7] RIN 2060-AK26 AGENCY: Environmental Protection Agency. ACTION: Notice of Proposed Rulemaking. SUMMARY: Pursuant to the U.S. Environmental Protection Agency's (EPA or “we”) Significant New Alternatives Policy (SNAP) program, this action proposes to list n-propyl bromide (nPB) as an unacceptable substitute for methyl chloroform, chlorofluorocarbon (CFC)-113, and hydrochlorofluorocarbon (HCFC)-141b when used in adhesives or in aerosol solvents because nPB in these end uses poses unacceptable risks to human health when compared with other substitutes that are available. In addition, EPA takes comment on alternate options that would find nPB acceptable subject to use conditions in adhesives or in aerosol solvents. This action also proposes to list nPB as acceptable, subject to use conditions, as a substitute for methyl chloroform, CFC-113, and hydrochlorofluorocarbon (HCFC)-141b in the coatings end use. This proposal supersedes EPA's proposal of June 3, 2003 on the acceptability of nPB as a substitute for ozone-depleting substances for aerosols and adhesives.
