The main activity is the cleanup of the areas of concern. That was a commitment made in 1987 under the Great Lakes Water Quality Agreement.
Other commitments also involved improving our science base, developing lake-wide management plans for critical pollutants, and those plans have been developed. We are looking at implementation strategies for those plans so that on a lake-by-lake basis critical pollutants will be managed lake-wide. We're also modifying monitoring programs to support the implementation of those lake-wide management plans.
And the science continues. We're studying things like avian botulism and blue-green algae in Lake Erie, looking at sources, looking for next actions.
