WASHINGTON (AP) — The Supreme Court is getting down in the mud.

The justices said Monday they will hear an appeal of a federal court ruling that declared mud washing off logging roads is pollution. The federal appeals court in San Francisco ordered the Environmental Protection Agency to write regulations to reduce the amount of runoff from logging roads that reaches salmon streams.

Oregon and the timber industry filed separate appeals challenging the court ruling.

The Obama administration agreed with the challengers that the appeals court erred in its ruling. But it urged the high court to stay out of the case because Congress and the Environmental Protection Agency already are taking steps to address the appeals court ruling.
