Today's action revises the motor vehicle Inspection/ Maintenance Program Requirements final rule promulgated on November 5, l992. EPA proposed these revisions on June 28, l994, allowing stakeholders ample opportunity for review and comment, and is taking final action on the revisions to include additions and modifications, regarding State Implementation Plan submissions for states with nonattainment areas that are in a position to redesignate to attainment. The revisions specify SIP requirements only for areas that are subject to the basic Inspection/Maintenance program requirement and that otherwise qualify for redesignation from nonattainment to attainment for the carbon monoxide or ozone national ambient air quality standards. This rule allows such areas to defer adoption and implementation of some of the otherwise applicable requirements established in the original promulgation of the Inspection/Maintenance rule. It is an appropriate time to take this action since the rule applies only to areas that by virtue of their air quality classification are required to implement a basic I/M program and that submit, and otherwise qualify for, a redesignation request.
