Facilities Conducting Four Factor Analysis

Round 2 Regional Haze Program Planning

DEQ's Regional Haze Program works with facilities to implement pollution control plans to improve visibility and air quality at Oregon's national parks and wilderness areas. As part of this program, DEQ is providing information on each participating facility including correspondence, four factor analysis, and any resulting pollution control plans.

Information on each participating facility will be added when it is available.
