The Environmental Protection Agency published in the Federal Register of January 27, 2003, a direct final rule related to the Significant New Alternatives Policy (SNAP) program. Additional, new information was recently made available to EPA related to the calculation of the environmental impact of a fire suppression substitute that was listed as an acceptable substitute in the direct final rule. 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 rule, for use of the substitute in fire protection. This document identifies and makes the above correction.
