Court Won’t Hear Challenge to Clean Air Regs

The U.S. Supreme Court on Tuesday declined to hear a challenge to new clean air requirements limiting sulfur dioxide emissions, The Memphis Daily News reports. Several corporations, industrial associations and state governments have complained that the Environmental Protection Agency’s required emission levels are lower than mandated by law to protect public health. The U.S. Court of Appeals for the District of Columbia refused to overturn the EPA's decision and the high court justices refused to reconsider that ruling.
