The commission that oversees water quality regulations in Iowa is considering adoption of rules that align state regulations with those imposed by the federal Clean Water Act.
The Environmental Protection Commission's proposed rules primarily give the Iowa Department of Natural Resources authority to issue permits that regulate manure handling for livestock farms shown to discharge manure into waterways.
Permits aren't required, however, and environmental groups say the rules are too weak and too friendly to livestock farms.
Iowa Citizens for Community Improvement wants all farms with spills to be required to get a permit. The group also wants five members of the nine-member, governor-appointed commission to abstain from voting because they have financial interests in livestock farming.
A vote on the rules is scheduled for Tuesday morning.
