Adequacy Determination for the Grants Pass, Oregon PM10

The Environmental Protection Agency (EPA) is notifying the public of its finding that the Grants Pass, Oregon second 10-year limited maintenance plan (LMP) for particulate matter with an aerodynamic diameter of a nominal 10 microns or less (PM10) is adequate for transportation conformity purposes. The LMP was submitted to the EPA by the State of Oregon Department of Environmental Quality (ODEQ or the State) on April 22, 2015. As a result of our adequacy finding, regional emissions analyses will no longer be required as part of the transportation conformity demonstrations for PM10 for the Grants Pass area.
