PORTAGE, Ind. (AP) -- Environmentalists are urging Indiana residents to attend one of three public meetings on revised state water quality rules they say will lead to more pollution.

State environmental officials will hold the first meeting Wednesday night in Portage, followed by an Aug. 25 meeting in Garrett and another one Aug. 26 in Seymour.

The revised rules define the circumstances under which an industrial plant or other facility can increase pollution to lakes and streams inside and outside the Great Lakes basin.

Environmentalists fear the revised rules would allow facilities to increase pollution without proving it’s necessary, particularly to Lake Michigan.

Rae Schnapp of the Hoosier Environmental Council says Indiana’s revised rules “are “fraught with loopholes.”
