Protection of Stratospheric Ozone: Notice 17 for Significant New 
Alternatives Policy Program; Correction

AGENCY: Environmental Protection Agency.

ACTION: Notice of acceptability; correction.

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

SUMMARY: The Environmental Protection Agency published in the Federal 
Register of December 20, 2002, a Notice of Acceptability related to the 
Significant New Alternatives Policy (SNAP) program. Additional, new 
information was recently made available to EPA and provided updated 
information related to the calculation of the environmental impact of a 
fire suppression substitute that was listed as an acceptable substitute 
in the Notice. Based on this new information, EPA is correcting the 
atmospheric lifetime and global warming potential (GWP) listed for the 
substitute fire suppression agent. This correction does not change 
EPA's finding of acceptability, as set forth in the Notice, for use of 
the substitute in fire protection. This document identifies and makes 
the above corrections.

DATES: This corrections is effective on April 7, 2003.

ADDRESSES: Information relevant to this correction notice is contained

SUPPLEMENTARY INFORMATION: The Environmental Protection Agency 
published in the Federal Register of December 20, 2002 (67 FR 77927), a 
Notice of Acceptability related to the Significant New Alternatives 
Policy (SNAP) program. After publication of FR Doc. 02-32130 on 
December 20, 2002, additional, new information was recently made 
available to EPA provided updated information related to the 
calculation of the environmental impact of a fire suppression 
substitute that was listed as an acceptable substitute in the notice. 
Based on this new information, EPA is correcting the atmospheric 
lifetime and global warming potential (GWP) listed for C6-
perfluoroketone, a substitute fire suppression agent. EPA's evaluation 
of this new information is available in EPA air docket A-2002-08 at the 
address described above under ADDRESSES. This correction does not 
change EPA's finding of acceptability for use of C6-perfluoroketone as 
a substitute for halon 1301 in total flooding fire suppression 
applications in both normally occupied and unoccupied areas.
    In FR Doc. 02-32130, published on December 20, 2002 (67 FR 77927), 
under ``Supplementary Information,'' section I ``Listing of Acceptable 
Substitutes,'' make the following corrections:
    1. On p. 77931, in the first full paragraph in the third column, 
under the heading ``Environmental Information,'' correct the sentence 
to read ``C6-perfluoroketone has no ozone depletion potential, a global 
warming potential of between four and seven relative to CO2 over a 100-
year time horizon, and an atmospheric lifetime of up to two weeks.''
    2. On p. 77932, in the first paragraph of the first column, under 
the heading ``Comparison to Other Fire Suppressants,'' correct the 
second sentence to read ``With no ozone-depletion potential, a global 
warming potential of between four and seven, and an atmospheric 
lifetime of up to two weeks, C6-perfluoroketone provides an improvement 
over use of halon 1301, hydrochlorofluorocarbons (HCFCs) and 
hydrofluorocarbons (HFCs) in fire protection.''
