SUPPLEMENTARY INFORMATION:

This document proposes to take action to approve the definition of greenhouse gas, and add greenhouse gases to emission inventory requirements. We have published a direct final rule approving the State's SIP revision (s) in the “Rules and Regulations” section of this Federal Register, because we view this as a noncontroversial action and anticipate no relevant adverse comment. We have explained our reasons for this action in the preamble to the direct final rule. If we receive no adverse comment, we will not take further action on this proposed rule. If we receive adverse comment, we will withdraw the direct final rule and it will not take effect. We would address all public comments in any subsequent final rule based on this proposed rule. We do not intend to institute a second comment period on this action. Any parties interested in commenting must do so at this time. For further information, please see the information provided in the ADDRESSES section of this document.
