The U.S. Environmental Protection Agency (EPA) is proposing a regulation to revise outdated timing-related references in the Inspection and Maintenance (I/M) rule such as submission dates, start dates, evaluation dates, and other milestones and/or deadlines to make them relevant for areas that will be newly required to begin I/M programs as a result of being designated and classified under the 8-hour ozone standard.

Summary of the Proposed Rule
The Agency is proposing minor revisions to the Motor Vehicle Inspection/Maintenance (I/M) regulation to update submission and implementation deadlines and other timing-related requirements to reflect the nonattainment designations under the new 8-hour National Ambient Air Quality Standards (NAAQS) for ozone. This proposal will also change the model year requirements in the modeling calculation which will establish the emission reduction target for I/M benefits
Key Elements of the Proposed Rule
This proposal would:
- Establish the implementation deadline for new I/M programs required under the 8-hour standard as 4 years after the effective date of classification under the 8-hour standard. This proposal would also clarify that the deadline for beginning OBD testing will be "coincident with program start up" for areas newly required to implement I/M as a result of being classified under the 8-hour ozone standard.
- Change the current, fixed deadline for beginning program evaluation testing to the more relative deadline of "no later than 1 year after program start up."
- Establish the submission deadline for new I/M state implementation plans (SIPs) required under the 8-hour standard. The submission deadline dates would be set for 1-year after the effective date of final action on the current proposal.
Background
Under the Clean Air Act as amended in 1990, certain ozone nonattainment areas are required to adopt vehicle I/M programs as one of the mandatory control measures used to reach attainment. On April 30, 2004 (69 FR 23951), EPA published a notice of final rulemaking addressing several key requirements related to the implementation of the 8-hour ozone standard originally promulgated on July 18, 1997 (62 FR 38856). Among other things, the 8-hour ozone standard implementation rule established deadlines for meeting the 8-hour ozone standard based upon a given area's degree of non-attainment. The rule also addresses when SIPs and attainment demonstration plans must be submitted.
As a result of the changes finalized by the 8-hour implementation rule, EPA is issuing a notice of proposed rulemaking to revise outdated timing-related references in the I/M rule such as submission dates, start dates, evaluation dates, and other milestones and/or deadlines to make them relevant for areas that will be newly required to begin I/M programs as a result of being designated and classified under the 8-hour ozone standard.
