30 July 2007 — The Leland Olds Station is engulfed in a $410-million project that will continue for more than three years.
Construction has begun at the coal-based power plant, located near Stanton, N.D., to install wet limestone scrubbers that will remove emissions of sulfur dioxide. The preliminary work of moving utilities and buildings has been completed, and now construction has started on the scrubber foundations.
Mark Nygard, construction supervisor, said that work on the foundations will continue into fall 2008. “We will have the new chimney foundation completed this year, and then we’ll start work on the 600-foot concrete chimney shell next spring,” he said.
The project has been in the works since early 2006. Myron Steckler, Basin Electric’s manager for the Leland Olds emissions control project, said the Environmental Protection Agency’s Regional Haze Rule, a major effort to improve air quality in national parks and wilderness areas, requires additional emissions control through implementation of the technology identified in the Best Available Retrofit Technology (BART) determination process. The expected enforceable compliance date to install the new technology is at the end of 2013.
“The Leland Olds Station is in full compliance with all its existing federal and state environmental permits,” Steckler said, “but by adding the scrubbers, we can be sure that Leland Olds can operate for an additional 20 to 30 years providing jobs and economic benefits to the area long into the future.”
Commercial operation for Unit 2 scrubber is scheduled for 2009 and 2010 for Unit 1.
