The day after a coal-ash retention pond broke at a Tennessee Valley Authority power plant in Kingston, Tenn., closing a river and inundating about a dozen homes with sludge, 39 environmental groups asked President-elect Barack Obama to reject a pending regulation that would make it easier to dispose of such ash in abandoned coal mines.
