Preliminary comments: Regional Haze SIP Revision - 2nd 10-Year Plan

Send us comment

Ecology revised the 2010 Regional Haze State Implementation Plan (SIP). We are required to do this about every 10 years to show improvements to visibility in the 3 national parks and 5 wilderness areas in Washington (mandatory Class I federal areas). We are asking for comments on our preliminary draft plan before we hold an official public comment period on the next draft.
