Future DuSable Park

The small parcel of land proposed to become DuSable Park is a 3.5-acre peninsula just east of Lake Shore Drive between the Chicago River and the Ogden Slip. The parcel is owned by the Chicago Park District. When it is developed, the park is expected to be dedicated to Chicago's first non-Native-American settler, Jean Baptiste Pointe du Sable. He was a French and African American entrepreneur from the island of Haiti who lived and operated a trading post at the mouth of the Chicago River from 1779 to about 1800.

Under a June 2017 cooperative agreement, EPA is providing $6.8 million to the Chicago Park District to continue an ongoing cleanup.  In 2012, the Chicago Park District received about $250,000 through a previous cooperative agreement to clean up contaminated areas on the DuSable Park site. Contractors for the park district, with EPA oversight, removed more than 115 cubic yards of thorium-contaminated soil. Funding for the cleanup also comes from a 2014 fraud settlement in which Kerr-McGee Corp. and Anadarko Petroleum Corp. agreed to pay for environmental cleanups at former Kerr-McGee sites across the country.  This funding also paid for the removal of nearly 1,000 additional cubic yards of thorium-contaminated soil.

A small part of the elevated portion of the Navy Pier Flyover will pass over DuSable Park and be supported by several columns that will be placed in the park near Lake Shore Drive.

Streeterville Cooperative Agreement

The city of Chicago is cleaning up high levels of thorium contamination in the “Streeterville Thorium Investigation Area.” The area is bounded on the south by Randolph Street, on the west by Michigan Avenue, on the east by Lake Michigan and on the south by Erie Street. Through a 2012 legal agreement, EPA is providing $2.5 million to help fund the cleanup of some city sidewalks, streets, and parkways. The project may last through Aug. 31, 2025, subject to potential grant extensions.

Project at 545 N. McClurg Court

This project has been completed.

Prior testing determined that there was thorium-contaminated soil in some subsurface areas of the site. The project’s owner signed a legal agreement with the EPA to find and remove the thorium-contaminated soil. EPA oversaw that work. Contractors used specialized radiation-detecting instruments to scan the soil during excavation. As thorium-contaminated material was discovered, it was immediately secured, covered and packaged for removal to a licensed radioactive waste disposal facility.

Project at 455 North Park Drive

This project has been completed.

Prior testing determined that there was thorium-contaminated soil in some subsurface areas of the site. The project’s owner signed a legal agreement with EPA to find and remove the thorium-contaminated soil.  EPA oversaw that work.  Contractors used specialized radiation-detecting instruments to scan the soil during excavation. As 355 cubic yards of thorium-contaminated material was discovered, it was immediately secured, covered and packaged for removal to a licensed radioactive waste disposal facility.

Project at 465 N. Park Drive

This project has been completed.

In 2008, an administrative settlement agreement and order on consent were issued for 319 E. Illinois St., aka 465 N. Park Drive.  During 2012 and 2013, about 12 cubic yards of thorium-contaminated soil was removed.  The site was also covered with gravel and used as a staging area during the cleanup of the adjacent property at 455 N. Park Drive. In 2016, a high-rise residential building was erected here.

Project at 515 N. Peshtigo Court (aka 500 N. Lake Shore Drive)

This project has been completed.

More than 160 yards of subsurface thorium-contaminated material was secured, covered and packaged for removal to a licensed radioactive waste disposal facility. A 45-floor residential tower was built here after the former three-story masonry structures were demolished.

Project at 224-228 E. Ontario St. (OU22)

This project has been completed.

Thorium testing was done here because the location of a new 20-story hotel is within the Streeterville Thorium Monitoring Area. The project’s owner signed a legal agreement with EPA to remove thorium-contaminated soil, if any was found.  Contractors for the project’s owner used specialized radiation-detecting instruments to scan the soil during excavation. EPA oversaw that work; however, no thorium was detected.

Project at 510 N. Peshtigo Court (OU10) (aka 451 E. Grand Ave., aka 400 E. Illinois)

This project has been completed.

Before a 67-story residential high-rise building was constructed here, prior testing found thorium-contaminated soil nearby. The developer had signed a legal agreement with EPA to find and remove the tainted soil, if encountered.  EPA oversaw that work. Contractors are used specialized radiation-detecting instruments to scan the soil during excavation. As 8 cubic yards of thorium-contaminated material was discovered, it was immediately secured, covered and packaged for removal to a licensed radioactive waste disposal facility.

Navy Pier CTA Electric Bus Charging Station

The Chicago Transit Authority is constructing an electric bus charging station at Navy PierExit. The units will allow charging within 5 to 10 minutes allowing buses to return to service quickly.

This project is located within the “Lindsay Light Streeterville Thorium Monitoring Area” near Navy Pier at the intersection of East Grand Avenue and Park Drive. EPA is providing technical oversight to CTA and its contractors to ensure that monitoring for thorium-contaminated soil is conducted during construction activities.  And, if contamination is found, that it is removed and disposed of properly. To date, approximately 18 cubic yards of thorium-contaminated soil have been removed.

EPA will continue to oversee the work through the summer.  Construction of the charging station is scheduled to be completed by the end of 2020.
