Just last week, the bill H.R. 1310, which will effectively ban mountaintop removal/valley fill mining, was introduced to the House by Rep. Frank Pallone [NJ], Rep. John Yarmuth [KY] and Rep. Reichert [WA-R], with 116 co-sponsors.
Jeff Biggers of the Huffington Post wrote a great piece about the new legislation: http://www.huffingtonpost.com/jeff-biggers/black-waters-no-more-clea_b_171793.html
