Northern States Power Co.-Minnesota, a unit of Xcel Energy (NYSE: XEL), sued the U.S. Environmental Protection Agency (EPA), asking the agency to reconsider its methodology for calculating allowable emissions for those power plants under the Cross State Air Pollution Rule (CSAPR).
Xcel also filed a petition with the District of Columbia Circuit Court of Appeals Oct. 10, saying the CSAPR does not give the utility credit for emissions reductions made at the Riverside and High Bridge power plants in Minnesota. Both plants were built as coal-fired power plants, but High Bridge was repowered in 2008 and Riverside in 2009 as gas-fired plants. The new plants reduced sulfur dioxide (SO2) and nitrogen oxide (NOx) emissions by 95 percent.
“Such early actions must be correctly treated, not penalized,” said Judy Poferl, president and CEO of NSP-MN. “Revising the rule will not only avoid unwarranted costs of compliance with CSAPR, but also will ensure proper treatment of early action under the many other new environmental regulations anticipated to take effect in the future.”
CSAPR is designed to address the long-range transport of emissions of SO2 and NOx across state lines. It applies to 27 states in the Eastern and Midwest U.S.
