Group challenges Grayling fish hatchery expansion

​Environmental groups are asking the state to take back permission for a fish hatchery to expand its operations on a legendary trout stream. The operator has been given permission to raise as much as 300,000 pounds of rainbow trout in the facility. 

The complaint says there are not enough protections to ensure the Grayling Fish Hatchery won’t allow diseases and parasites to escape into the Au Sable River.

Marvin Roberson is with the Sierra Club.

“The permit doesn’t require those pools to be monitored to see whether or not fish or parasites or diseases are escaping from the facility, and we think it’s outlandish to say 'you don’t have to check to see whether those things are getting out,'” Roberson said.

A spokesman for the state Department of Environmental Quality says the agency is closely monitoring the water around the hatchery, and will act quickly if there’s a problem.
