GRANTS PASS, Ore. (AP) — The timber industry is hoping that the U.S. Supreme Court will maintain business as usual on controlling muddy water running off logging roads into salmon streams.

The high court decided Monday to take up a 9th U.S. Circuit Court of Appeals ruling that federal regulators should treat stormwater on industrial timberlands the same as pollution discharged from a factory, changing the longstanding practice that treats it like water coming off farm fields.
