DEQ's proposed revisions to air pollution control rutes adopted in 2009 for the PGE Boardman coal-fired power plant were approved by the 

• 	 Air Quality Home Environmental Q,Jality Commission at the commission's December 2010 meeting. The revisions allow PGE to choose to close the coal-fired pow 

• 	 Air Quality Index plant near Boardman by 2020 and satisfy federal requirements for air quality and pollution controls to reduce haze emiSSions. The rules also: 

• 	 AirToxics • Repeal the 2009 rule that requires expensive poHvtion control equipment and allows the plant to operate until 2040 • 	 Burning and • 	 Ensure the permanent closure of the Boardman coal-fired boiler no later than Dec. 31, 2020. smoke • 	 Use dry sorbent injection controls to meet federal regulations for sulfur dioxide control (as proposed by DEQ in its 2018 option), • 	 Columbia Gorge • 	 A more stringent sulfur dioxide limit from 2018-2020 as proposed by DEQ.

Q,Jality Rating DEQ concluded that the proposed BART controls, when combined with the penmanent closure of plant no later than 2020, meet federal • 	 Woodstoves requirements and provide a significant environmental and public health benefit fOr Oregon. In brief, DEQ's rules: 

• 	 Reduce haze forming emissions by 48 percent in the 2011 to 2019 timeframe and eliminate these pollutants completely after closure, 

• 	 Significantly improve visibility in 14 Class I wilderness areas in Oregon and Washington. 

• 	 Significantly improve visibility In the Columbia River Gorge National Scenic Area and reduce acid deposition, lessening the risk to Native 

American natural and cultural resources. 

• 	 Permanently eliminate approximately 4,000,000 tons per year of greenhouse gasses and all of the plant's mercury emissions, which curr· range from 137 to 281 pounds per year.
