Former McLouth Steel Corp Site

Phase I documents have been received and are posted below. These were required by the Phase I Corrective Action Consent Order for the facility. EGLE is currently using the information from these to build an enforcement referral to generate a Phase II Corrective Action Consent Order for more remedial action.

New Area of Interest Draft Work Plan

The Area of Interest Interim Measures Work Plan is in response to the identification of a New Area of Interest at the northwest portion of the RTRR property. EGLE MMD staff conducted an inspection, and collected samples on March 15th, 2023, after receiving information from a community member. It appeared that the recent excavation to extend the existing railroad exposed shallow groundwater that has been in contact with buried calcium hydroxide waste. The MMD notified RTRR of the results on March 16th, 2023, and required immediate action to protect the community from potential human exposure. RTRR installed fencing to prevent people from accessing the site. A second sampling event was conducted by MMD staff on March 29th, 2023, after observing a substance exhibiting a milky appearance seeping into Monguagon Creek (Huntington Creek) from the western shoreline during the first sampling event. Based on the data collected from these inspections and sampling events MMD has determined that the northwest area of the site is a New Area of Interest, and an Interim Measures Work Plan is required to address the high pH liquid in the excavation area and propose actions to immediately prevent the discharge of high pH groundwater into Monguagon Creek. The work plan has been reviewed by EGLE’s MMD and approved with several modifications including revising the work plan to include proposed actions to immediately prevent the discharge of impacted groundwater into Monguagon Creek.

Consent Order

EGLE and RTRR entered into a Consent Order, called a Corrective Action Consent Order, or CACO. Pursuant to the CACO, RTRR will undertake certain corrective actions within the approximately 76-acres that comprise the northern portion of the former McLouth Steel Corp facility.

RTRR has agreed to do the following:

• Perform the first phase of the corrective action (environmental investigation and response activities) that includes investigation of the five known waste management units, or WMUs, on the northern portion of the site.
• Clean up the WMUs if needed.
• Investigate groundwater contamination.
• Control dust.
• Evaluate stormwater management options to eliminate flow to the Trenton Channel of the Detroit River.

EGLE will use the information collected during the first phase of the corrective action and other sources to help determine if additional phases of corrective action are necessary.
