Portland General Electric Company operates two fossil fuel-fired electric generating plants in the Eastern Region. The Coyote Springs Plant is located at the Port of Morrow in Boardman and it includes two natural gas-fired combined cycle combustion turbines. The Boardman Plant is located on Tower Road about 10 miles south of Boardman and it includes one existing coal-fired electric generating unit and one proposed natural gas-fired combined cycle combustion turbine (aka Carty Plant). This page is set up to provide information about the sources, including pending applications, draft permits, final permits, and public notices.
DEQ regulation of PGE Boardman
DEQ's proposed revisions to air pollution control rules adopted in 2009 for the PGE Boardman coal-fired power plant were approved by the Environmental Quality Commission at the commission's December 2010 meeting. The revisions allow PGE to choose to close the coal-fired power plant near Boardman by 2020 and satisfy federal requirements for air quality and pollution controls to reduce haze emissions. The rules also:
- Repeal the 2009 rule that requires expensive pollution control equipment and allows the plant to operate until 2040
- Ensure the permanent closure of the Boardman coal-fired boiler no later than Dec. 31, 2020.
- Use dry sorbent injection controls to meet federal regulations for sulfur dioxide control (as proposed by DEQ in its 2018 option).
- A more stringent sulfur dioxide limit from 2018-2020 as proposed by DEQ.
- Include a 2015 closure option if PGE decides to close the plant earlier than 2020.

Anticipated results of the regulation
DEQ concluded that the proposed BART controls, when combined with the permanent closure of plant no later than 2020, meet federal 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 currently range from 137 to 281 pounds per year.
