EPA has issued a final rule to clarify when industrial facilities making changes to equipment or processes may need to retain records documenting their emissions even if the changes do not trigger Clean Air Act New Source Review (NSR) permitting requirements. The rule clarifies when facilities must keep records and report emissions when a "reasonable possibility" test shows that projected emissions increases could equal or exceed 50 percent of the Clean Air Act's NSR significant levels for any pollutant.

This rule does not change permitting requirements. The "reasonable possibility" test examines the difference between a project's baseline emissions and the sum of emissions projected to result from the project and emissions attributable to independent factors such as growth in market demand.
