This site displays a prototype of a “Web 2.0” version of the daily Federal Register. It is not an official legal edition of the Federal Register, and does not replace the official print version or the official electronic version on GPO’s govinfo.gov.
The documents posted on this site are XML renditions of published Federal Register documents. Each document posted on the site includes a link to the corresponding official PDF file on govinfo.gov. This prototype edition of the daily Federal Register on FederalRegister.gov will remain an unofficial informational resource until the Administrative Committee of the Federal Register (ACFR) issues a regulation granting it official legal status. For complete information about, and access to, our official publications and services, go to About the Federal Register on NARA's archives.gov.
The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.

Notice of proposed rulemaking; correction.
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.Start Further Info

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 Start Printed Page 56810statements 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).Start Signature
