"In a victory for environmentalists, the EPA is going to require that PNM reduce nitrogen oxide emissions at its four-corners generating station by 80 percent. The company and the state had both recommended a 20 percent reduction.
The EPA is giving PNM two additional years to meet the requirement at its 40-year-old, coal-fired San Juan power plant. It must complete the work in five years instead of the three-year period that had been discussed.
PNM says the EPA plan will cost upwards of $750 million while the company's alternative would have cost about 10 percent of that amount. PNM says customers may well have to shoulder the costs.
PNM says it plans to appeal the decision."
