Protection of Stratospheric Ozone: Listing of Substitutes for 
Ozone-Depleting Substances-n-Propyl Bromide; Correction

AGENCY: Environmental Protection Agency.

ACTION: Notice of proposed rulemaking; correction.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) published in the 
Federal Register of June 3, 2003, a Notice of Proposed Rulemaking 
related to the Significant New Alternatives Policy (SNAP) program's 
review of n-propyl bromide. During the public comment period, members 
of the public requested clarification or correction of a number of 
statements in the preamble to the proposed rule. This document 
identifies, corrects, and clarifies these portions of the preamble.

FOR FURTHER INFORMATION CONTACT: Margaret Sheppard. Before October 16, 
2003, contact Ms. Sheppard by telephone at (202) 564-9163, by fax at 
(202) 565-2141, by e-mail at sheppard.margaret@epa.gov, or by mail at 
U.S. Environmental Protection Agency, Mail Code 6205J, Washington, DC 
20460. Overnight or courier deliveries should be sent to the office 
location at 501 3rd Street, NW., Washington, DC 20001. Further 
information can be found by calling the Stratospheric Protection 
Hotline at (800) 296-1996, or by viewing EPA's Ozone Depletion World 
Wide Web site at http://www.epa.gov/ozone/snap/. On and after October 
16, 2003, contact Ms. Sheppard by telephone at (202) 343-9163, by e-
mail at sheppard.margaret@epa.gov, or by mail at U.S. Environmental 
Protection Agency, Mail Code 6205J, Washington, DC 20460. Overnight or 
courier deliveries on and after October 16, 2003 should be sent to the 
new office location at 1310 L Street, NW., Washington, DC 20005.

SUPPLEMENTARY INFORMATION: The Environmental Protection Agency 
published in the Federal Register of June 3, 2003 (68 FR 33284), a 
Notice of Proposed Rulemaking related to the Significant New 
Alternatives Policy (SNAP) program's review of n-propyl bromide. During 
the public comment period, members of the public requested 
clarification or correction of certain

statements in the proposal, FR Doc. 03-75043, published on June 3, 
2003.
    In the proposed rule, FR Doc. 03-75043, published on June 3, 2003, 
in the ``Supplementary Information'' section make the following 
corrections:
    1. On page 33286 at the top of the third column, the chemical name 
for HCFC-141b is corrected to read ``1,1-dichloro-1-fluoroethane.''
    2. On page 33286 on the 8th line down from the top of the third 
column, the chemical name for HCFC-225cb is corrected to read ``1,3-
dichloro-1,1,2,2,3-pentafluoropropane.''
    3. On page 33286, on the 21st line down from the top of the third 
column, the chemical name for HFC-365mfc is corrected to read 
``1,1,1,3,3-pentafluorobutane.''
    4. On page 33304, at the bottom of the third column, footnote 15 is 
corrected to read as follows:

    ``The recommended AEL for nPB is lower than that for many 
acceptable solvents (HFEs, ketones, HFCs, HCFC-225ca/cb, 
hydrocarbons), but is higher or comparable to the AEL for some 
acceptable solvents (d-limonene, VMSs, dichlorobenzotrifluoride, 
HCFC-123, methylene chloride, PCBTF). However, a direct comparison 
between two compounds with different AELs does not necessarily mean 
that using a compound with a lower AEL is more risky. Actual 
exposure levels will vary based upon factors other than the AEL, 
such as emission controls in place, work practices, ventilation, 
rate of spraying, and vapor pressure of the solvent.''

    5. On page 33311, in the first column under the first bullet point, 
the following sentence appears beginning in the 51st line: ``Recent 
regulations for hazardous air pollutants disallow use of methylene 
chloride in foam fabrication facilities.'' This sentence is corrected 
to read as follows: ``Recent regulations for flexible polyurethane foam 
fabrication facilities that are major sources of hazardous air 
pollutants disallow use of methylene chloride-based adhesives at loop 
slitters and associated equipment used to apply adhesives to bond 
foam.''
    The National Emissions Standard for Hazardous Air Pollutants 
(NESHAP) for new and existing sources at flexible polyurethane foam 
fabrication facilities, published in the Federal Register of April 14, 
2003 (68 FR 18062), does not generally disallow use of methylene 
chloride in all foam fabrication facilities. The NESHAP disallows the 
use of HAP-based adhesives at loop-slitter affected sources at plants 
that are major source of hazardous air pollutants (HAPs), in accordance 
with the compliance dates set forth in the NESHAP. Stationary sources 
emitting, or having the potential to emit, less than 10 tons per year 
of a particular HAP, such as methylene chloride, and less than 25 tons 
per year of any combination of HAPs are not regulated as major sources 
under the NESHAP and are thus considered ``area sources.'' EPA has 
listed flexible foam fabrication operations as an area source category 
for further scrutiny and may address HAP emissions from area sources 
under section 112(k) of the Clean Air Act in the future.
    Users of adhesives containing methylene chloride must comply with 
applicable requirements of the Methylene Chloride Standard issued by 
the Occupational Safety and Health Administration (29 CFR 1910.1052).
