The Environmental Protection Agency (EPA) is proposing to approve a plan for the Wallula area in Washington State that addresses the second 10-year maintenance period for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM<INF>10</INF>). This plan relies upon the control measures contained in the first 10-year maintenance plan, with revisions to reflect updated permits and agreements, also proposed for approval in this action. Lastly, we are proposing to take final agency action on high wind and wildfire exceptional events associated with the Wallula area.
The agency’s own summary, as published.
