Approval and Disapproval and Promulgation of Air Quality Implementation Plans; Colorado; Revision to Definitions; Construction Permit Program; Regulation 3
EPA is proposing to partially approve and partially disapprove State Implementation Plan (SIP) revisions submitted by the State of Colorado on June 20, 2003 and April 12, 2004. The intended effect of this proposal is to approve those portions of the revisions to Colorado's Regulation 3 that place restrictions on increment consumption, add innovative control technology as an alternative to BACT requirements and make other changes as described in more detail below. In addition, EPA proposes to disapprove those portions of the rule revisions that EPA determined are inconsistent with the Clean Air Act (CAA), including provisions relating to pollution control projects. This action is being taken under section 110 of the CAA.
Approval and Promulgation of Implementation Plans; Albuquerque/Bernalillo County, NM; Interstate Transport of Pollution
The EPA is approving a revision to the Albuquerque/Bernalillo County, New Mexico State Implementation Plan (SIP) to address the ``good neighbor'' provisions of the Clean Air Act (CAA) section 110(a)(2)(D)(i), for the 1997 ozone and the 1997 fine particulate matter (PM2.5) National Ambient Air Quality Standards (NAAQS) as it applies to Albuquerque/Bernalillo County. The revision addresses one element of CAA section 110(a)(2)(D)(i), which pertains to prohibiting air pollutant emissions from within a state to significantly contribute to nonattainment of the ozone and PM2.5 NAAQS in any state. The Albuquerque/Bernalillo Air Quality Control Board (AQCB) is responsible for the portion of the New Mexico SIP that applies in Bernalillo County, which encompasses the City of Albuquerque. This rulemaking action is being taken under section 110 of the CAA.
Revisions To In-Use Testing for Heavy-Duty Diesel Engines and Vehicles; Emissions Measurement and Instrumentation; Not-to-Exceed Emission Standards; and Technical Amendments for Off-Highway Engines
This NPRM proposes to make several revisions to EPA's mobile source emission programs and test procedures. EPA believes that each of these is minor and non-controversial in nature. Most of the proposed changes arise from the results of the collaborative test program and related technical work we conducted for the highway heavy-duty diesel in-use testing program. Most noteworthy here is the proposal to adopt a particulate matter measurement allowance for use with portable emission measurement systems. Related to this are two provisions to align the in-use program timing requirements with completion of the program as required in current regulations and the incorporation of revisions to a few technical requirements in the testing regulations based on information learned in this and one other test program. Finally, the NPRM proposes to modify a few transitional flexibilities for locomotive, recreational marine, and Tier 4 nonroad engines and incorporates a handful of minor corrections.
Revisions to In-Use Testing for Heavy-Duty Diesel Engines and Vehicles; Emissions Measurement and Instrumentation; Not-to-Exceed Emission Standards; and Technical Amendments for Off-Highway Engines
EPA is taking direct final action on several revisions to EPA's mobile source emission programs standards and test procedures. EPA believes that each of these is minor and non-controversial in nature. Most of the changes arise from the results of the collaborative test program and related technical work we conducted for the highway heavy-duty diesel in-use testing program.

Related to this are two provisions to align the in-use program timing requirements with completion of the program as required in current regulations and the incorporation of revisions to a few technical requirements in the testing regulations based on information learned in this and one other test program. Finally, the DFR modifies a few transitional flexibilities for locomotive, recreational marine, and Tier 4 nonroad engines and incorporates a handful of minor corrections.
