(7/1/05) EPA will maintain New Source Review (NSR) requirements that will be used by states and communities across the country to meet the new, more protective 8-hour standard for ground-level ozone. The decision responds to an Earthjustice petition for reconsideration of the final rule to implement Phase 1 of the 8-Hour National Ambient Air Quality Ozone Standard. To ensure a smooth transition to the new 8-hour ozone standard, the NSR requirements will continue to apply to large sources of ozone-forming air pollutants in nonattainment areas for the 8-hour ozone standard, not the recently revoked 1-hour standard. EPA determined that the states should be allowed to remove 1-hour ozone New Source Review programs from their state implementation plans and replace them with a New Source Review program that is applicable to the 8-hour standard. By ensuring that new, rebuilt, or modified plants and facilities do not contribute to air quality problems, the NSR program is one tool that nonattainment areas use to meet and maintain EPA's air quality standards.
