With the nation's attention diverted by the drama over the debt ceiling, Republicans in the House of Representatives are loading up an appropriations bill with 39 ways - and counting - to significantly curtail environmental regulation. One would prevent the Bureau of Land Management from designating new wilderness areas for preservation. Another would severely restrict the Department of Interior's ability to police mountaintop-removal mining. And then there is the call to allow new uranium prospecting near Grand Canyon National Park. In fact, one measure - to forbid the Fish and Wildlife Service to list any new plants or animals as endangered - was so extreme that 37 Republicans broke ranks Wednesday and voted to strip it from the bill. Although inserting policy changes into appropriations bills is a common strategy when government is divided as it is now, no one can remember such an aggressive use of the tactic against natural resources. The new Republican majority seems intent on restoring the robber-baron era where there were no controls on pollution from power plants, oil refineries and factories," said Representative Henry A. Waxman, a California Democrat, excoriating the proposal on the floor.
