02-21945. Approval and Promulgation of Air Quality Implementation Plans for the State of Montana; Revisions to the Administrative Rules of Montana

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve State Implementation Plan (SIP) revisions submitted by the Governor of Montana on April 30, 2001, May 21, 2001 and December 20, 2001. The April 30, 2001 and December 20, 2001 submittals revise the State's Administrative Rules of Montana (ARM) by updating Incorporation by Reference rules. The May 21, 2001 submittal repeals the State's Sulfur Oxide—Primary Copper rule. We are also announcing that on February 1, 2002, we updated the delegation of authority for the implementation and enforcement of the New Source Performance Standards (NSPS) to the State. Finally, the Governor's April 30, 2001 submittal contains other SIP revisions which will be addressed separately. In the “Rules and Regulations” section of this Federal Register, EPA is approving the State's SIP revisions as a direct final rule without prior proposal because the Agency views these as noncontroversial SIP revisions and anticipates no adverse comments. A detailed rationale for the approval is set forth in the preamble to the direct final rule. If EPA receives no adverse comments, EPA will not take further action on this proposed rule. If EPA receives adverse comments, EPA will withdraw the direct final rule and it will not take effect. EPA will address all public comments in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period on this action. Any parties interested in commenting must do so at this time. Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment.

DATES:

Comments must be received in writing on or before September 27, 2002.

ADDRESSES:

Written comments may be mailed to Richard R. Long, Director, Air and Radiation Program, Mailcode 8P-AR, Environmental Protection Agency (EPA), Region 8, 999 18th Street, Suite 300, Denver, Colorado, 80202.
