Sewage spills into the lake already are a source of E. coli and other bacterial "bugs" that frequently lead to beach closings during the summer. Chicago banned swimming at Lake Michigan beaches 130 times last year; there were 178 beach closings in Lake County.
Under a policy change pushed by the Environmental Protection Agency, municipal sewage plants around the lake and across the country would gain explicit authority during wet weather to skip a required treatment that kills most of the bacteria, viruses and parasites in wastewater.

"We felt it was necessary to issue a definitive national statement that this is an acceptable option," said James Hanlon, director of the EPA's Office of Wastewater Management. "Continuing to prevent it may not be necessary from a public health standpoint."
The only other option, Hanlon and others say, is to spend billions of tax dollars upgrading treatment plants, something that appears unlikely in the current political climate. Federal funding for plant improvements and other clean water projects would be cut by nearly $500 million in Bush's proposed budget for 2005.
