AOCs

EPA has started a $12 million cleanup at the Lake Linden Recreation Area in Lake Linden, Michigan. Crews will remove about 13,300 cubic yards of sediment contaminated with lead, zinc, and polychlorinated biphenyls (PCBs).

Multiple cleanups around Detroit, including Monguagon Creek, Harbortown and Lower Rouge River’s Old Channel, will help restore the Detroit and Rouge Rivers. EPA and partners have already addressed about 400,000 cubic yards of contaminated sediment and restored more than 320 acres of habitat within the Detroit River AOC.

With the completion of the Thomson Reservoir project, all eight sediment cleanup projects are now complete for the Minnesota side of the St. Louis River Area of Concern. More than 1.9 million cubic yards of contaminated sediment have been addressed and over 1,000 acres of habitat have been restored across the AOC.

The Estabrook Falls Fish Passage Project modified the waterfall which prevented native fish from being able to swim upstream to critical spawning habitat during a majority of the year. After the project was completed, several Lake Sturgeon made their way upstream to Ozaukee County for the first time in over 100 years.

On March 30, U.S. Environmental Protection Agency resumed dredging contaminated sediment from the Lower Rouge River Old Channel in Detroit, Michigan. More than 100,000 cubic yards of sediment contaminated with coal tar and petroleum products will be remediated.

In early March, U.S. Environmental Protection Agency began the second year of its cleanup project on the Cuyahoga River in Gorge Metro Park. Throughout the duration of the project, EPA expects to remove more than 850,000 cubic yards of contaminated sediment from the river.

The project will remove over 240,000 cubic yards of contaminated canal and river bottom sediment and remediate over 100 acres of sediment at two sites in the AOC.

The Degradation of Benthos Beneficial Use Impairment was removed from the Eighteenmile Creek Area of Concern after federal, state, and local partners concluded that communities of benthic macroinvertebrates are not negatively impacted by PCBs.

In September, Muskegon Lake became the 8th overall U.S. AOC delisted and the 7th delisted under the GLRI. The designation comes after years of restoration and remediation work which restored more than 134 acres of habitat and 6,000 linear feet of shoreline.

The West Creek Flume Spillway Project, completed with a $7M Great Lakes Restoration Initiative grant, stabilized 6,500 linear feet of shoreline and restored fish passage.
