Can BLM remove NEPA from land use planning?

The Bureau of Land Management's (BLM) organic act, the Federal Land Policy and Management Act (FLPMA), charges the agency with managing public lands on the basis of "multiple use and sustained yield." Courts have held that several U.S. Environmental Protection Agency (EPA) actions are the functional equivalent of NEPA, including actions implementing the Clean Air Act (Portland Cement Ass n v. Ruckelshaus, 486 F.2d 375 (D.C. Cir. 1973)); the Federal Insecticide, Fungicide and Rodenticide Act (Envtl. Defense Fund, Inc. v. EPA, 489 F.2d 1247 (D.C. Cir. 1973)); the Ocean Dumping Act of 1972 (Maryland v. Train, 415 F. Supp. 116 (D. Md. 1976)); the Water Pollution Control Act (Weyerhaeuser Co. v. Costle, 590 F.2d 1011 (D.C. Cir. 1978)); and the Toxic Substances Control Act (Warren County v. North Carolina, 528 F. Supp. 276 (e.D.N.C. 1981)).
