The Environmental Protection Agency has picked Milwaukee  to kick off a series of upcoming public hearings on how to chart a course to  restore the Great Lakes.
 A public meeting is scheduled for Tuesday to discuss the  federal government's proposed blueprint to begin fixing some of the troubles  plaguing the world's largest freshwater system.
 The EPA and its sister federal agencies are focusing  their efforts on cleaning up sites contaminated with toxic waste, stopping the  onslaught of invasive species, reducing surface and sewer pollution flowing into  the lakes and restoring ecologically sensitive habitats.
