Portland, Ore., July 20, 2011 — Portland General Electric Co. reported progress implementing its 2020 plan for the Boardman Power Plant.
Under the plan, PGE is installing a suite of controls to reduce emissions from the plant, and has agreed to end the use of coal there by the end of 2020. The plan was adopted by state regulators last year.
The U.S. Environmental Protection Agency has approved the portions of Oregon's state implementation plan for regional haze that pertain to the Boardman 2020 plan. EPA approval of the plan was published in the Federal Register July 5, and was the final regulatory step in certifying that the 2020 strategy complies with Clean Air Act requirements for regional haze.
PGE installed the first of the planned emissions control retrofits this spring, including controls that are expected to filter out 90 percent of the plant's mercury emissions. PGE also replaced the plant's burners, which are expected to reduce nitrogen oxide emissions by more than 50 percent. This fall, PGE will begin testing a dry sorbent injection system that is expected to reduce permitted emissions of sulfur dioxide 67 percent by 2014 and 75 percent by 2018.
The EPA has proposed new emissions standards for coal- and oil-fired electric plants known as the MACT rule — for maximum achievable control technology. PGE and other stakeholders are offering comments to the EPA on its draft standards. The comment period ends August 4.
PGE operates the Boardman Plant and owns 65 percent of it. The other owners are Bank of America Leasing LLC, 15 percent; Idaho Power Co., 10 percent; and Power Resources Cooperative, 10 percent.
