Wisconsin officials propose new phosphorus limits

MADISON, Wis. (AP) State environmental officials have proposed new phosphorus limits for Wisconsin waters.

Department of Natural Resources water experts say the limits will prevent algae blooms and protect fish and insect populations.

The changes could be costly, though. The agency estimates more than 100 municipal wastewater treatment facilities may have to spend up to $1.13 billion to add filtration systems to meet the new standards. They also estimate up to 35 paper makers and food processors may have to spend up to $440 million.

The Natural Resources Board, which sets DNR policy, is expected to vote on Tuesday on whether to send the plan to a public hearing.
