Approval and Promulgation of State Implementation Plans; Montana; 
Interstate Transport of Pollution, New Definitions of PM and PM2.5

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve State Implementation Plan (SIP)

[[Page 10204]]

revisions submitted by the State of Montana on June 28, 2000 and April 
16, 2007. The revisions update Administrative Rules of Montana (ARM) 
provisions for Particulate Matter, and address Interstate Transport 
Pollution requirements of section 110(a)(2)(D)(i) of the Clean Air Act. 
On June 28, 2000, the Governor of Montana submitted revisions to ARM 
rules 17.8.101--Definitions; 17.8.308--Particulate Matter, Airborne; 
and 17.8.320--Wood Waste Burners. The June 28, 2000 submittal included 
also a declaration certifying the adequacy of the State SIP in regard 
to the infrastructure-related PM2.5 elements of section 110 
of the Clean Air Act (CAA). In the April 16, 2007 submission, the 
Governor requested EPA's review and approval of the ``Interstate 
Transport Rule Declaration'' adopted into the Montana SIP on February 
12, 2007. In that same letter, the Governor rescinded the State's 
earlier request for approval of Montana's SIP in regard to the 
infrastructure-related PM2.5 elements of section 110 of the 
CAA. In light of this rescission, EPA is not taking action on this 
declaration. This action is being proposed under section 110 of the 
Clean Air Act.
    In the ``Rules and Regulations'' section of this Federal Register, 
EPA is approving the State's SIP revision as a direct final rule 
without prior proposal because the Agency views this as a non-
controversial SIP revision 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 an 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.
