The Gowanus Canal has been designated as a toxic area for almost 15 years, and now the state is planning to formally look into what damage was caused to natural resources in the area.

The state has been working with the Environmental Protection Agency to clean up toxic chemicals in the area.

New York state’s Department of Environmental Conservation and federal agencies are asking for written comments from the public on their findings. This is the first step before they figure out how to restore damage caused by contamination and develop cleanup efforts.

The Gowanus Canal Conservancy says the cleanups and assessments at the Superfund site are the fastest-moving efforts at any site in the city.

The public comment period is open until April 15.
