          - 40 CFR Parts 52 and 81 
          - [NH-45-7172b; A-1-FRL-6906-3] 

# AGENCY:

Environmental Protection Agency (EPA). 

# ACTION:

Proposed rule. 

# SUMMARY:

The Environmental Protection Agency (EPA) is proposing to redesignate the Nashua, New Hampshire nonattainment area to attainment for the carbon monoxide (CO) air quality standard and is proposing to approve a Maintenance Plan that will insure that the Nashua area remains in attainment. The EPA is also proposing to redesignate the Manchester, New Hampshire nonattainment area to attainment for the CO air quality standard and is proposing to approve a maintenance plan that will insure that the Manchester area remains in attainment. Under the Clean Air Act, as amended in 1990 (the CAA), designations can be revised if sufficient data are available to warrant such revisions and the request to redesignate shows that all of the requirements of section 107(d)(E)(3) of the CAA have been met. EPA is proposing to approve the New Hampshire maintenance plans and other redesignation submittals because they meet the maintenance plan and redesignation requirements, and will ensure that the two areas remain in attainment. The approved maintenance plans will become a federally enforceable part of the New Hampshire State Implementation Plan (SIP). In this action, EPA is also proposing to approve the New Hampshire 1990 baseline emission inventories for both of these areas, transportation conformity budgets for both areas and a revision to the inspection and maintenance (I/M) SIP approved for the Nashua area. 

                        In the Final Rules Section of this                         **Federal Register**                        , EPA is approving the State's SIP submittal as a direct final rule without a prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no relevant adverse comments are received in response to this rule, no further activity is contemplated. If EPA receives relevant adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period. Any parties interested in commenting on this action should 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.
