1. SUPREME COURT
Big wins elusive for EPA in Clean Water Act showdowns
For U.S. EPA at the Supreme Court, it's been the best of times -- and the worst. In Clean Air Act cases, EPA is on a roll. The high court last term upheld a major EPA program for air pollution that drifts across state lines. It also barely trimmed a permitting program for greenhouse gases, leaving intact most of EPA's first round of climate regulations. But it's a different story when the Clean Water Act is in play.
