In mid-October, 26 states filed an amicus brief asking the U. S. Supreme Court to overturn Decker v. Northwest Environmental Defense Center, U.S. This court case classifies logging as an industrial, rather than agricultural, activity subject to Clean Water Act permitting for point sources. States write that this ruling contradicts U.S. Environmental Protection Agency and congressional directives that runoff from logging operations be treated as a nonpoint source mitigated with best management practices.
