## Abstract

The Environmental Protection Agency (EPA) is notifying the public of its finding that the Kent, Seattle, and Tacoma second 10-year limited maintenance plan (LMP) for particulate matter with an aerodynamic diameter of a nominal 10 microns or less (PM<INF>10</INF>) is adequate for transportation conformity purposes. The LMP was submitted to the EPA by the State of Washington Department of Ecology (Ecology or the State) on November 25, 2013. As a result of our adequacy finding, regional emissions analyses will no longer be required as part of the transportation conformity demonstrations for PM<INF>10</INF> for the Kent, Seattle, and Tacoma areas.
