From The Wall Street Journal: West Virginia lawmakers approved a measure on Saturday to roll back strict water-protection rules enacted last year after a chemical spill contaminated drinking water for 300,000 people in West Virginia’s capital. ... Environmental groups fought the measure. "It reduces the regulation of tens of thousands of above-ground storage tanks, some of which have the potential to contaminate drinking water," said Evan Hansen, president of Downstream Strategies, an environmental consulting company based in Morgantown, W.Va.
