Or. Admin. R. 340-252-0070 - Timeframe of Conformity Determinations

Any election by an MPO to shorten the timeframe of a conformity determination under 40 CFR 93.106(d) requires approval of the Department of Environmental Quality or the Lane Regional Air Protection Agency, as applicable. A shortened timeframe may be appropriate, for example, when projected future emissions fail to meet a Motor Vehicle Emissions Budget (MVEB) due to calculation methods that are inconsistent with the methods used to determine the MVEB. Such circumstances may exist for example, when emissions estimation methods have changed from those used to establish the MVEB.

NOTE: This rule is included in the State of Oregon Clean Air Act Implementation Plan as adopted by the Environmental Quality Commission under OAR 340-200-0040.
