The Michigan Freedom of Information Act (FOIA) provides all persons (except persons incarcerated in correctional facilities) with access to public records of public bodies. Requests to inspect or receive public records from EGLE must be in writing and describe the requested records with enough detail to enable the department to identify and locate the requested records. Some records are exempt from disclosure under the FOIA or another statute and thus will not be provided. A fee may be charged to process your request. Please note that many records are available that do not require a formal FOIA request.

Wolf Five LLC (Wolf) is the current owner of the former Wyckoff Steel Corporation (Wyckoff Steel) site located at 1000 General Drive, Plymouth, Michigan. Prior to Wyckoff Steel’s ownership, Ampco-Pittsburgh Corporation (Ampco) owned and operated the site from 1965 until 1987. Both Wycoff Steel and Ampco finished cold drawn steel and operated hazardous treatment, storage, and disposal units that handled waste from their steel production activities. Steel finishing operations were discontinued in 1990 and Wolf purchased the property in 2015.
While under Ampco’s ownership, Ampco removed and disposed of contaminated soils and demonstrated having met Michigan’s residential cleanup criteria for the majority of the contamination at the site. Groundwater contamination is still present at the site, but a restrictive covenant prohibiting use of the groundwater was implemented in 2006 and a groundwater monitoring system was installed that Ampco continues to operate and maintain today. Due to the restriction of groundwater use at the site it has received a limited residential closure designation. A limited residential closure means that the institutional control measure, in this case the restrictive covenant prohibiting the use of the groundwater, is used to prevent exposure to the contamination.
Pursuant to the 2015 Corrective Action Long Term Agreement (CALTA) between Wolf and EGLE, Wolf submitted a proposed Corrective Measures Implementation (CMI) Work Plan in September 2022. EGLE reviewed the CMI Work Plan and provided comments in January 2023. Wolf submitted a revised CMI Work Plan providing for Wolf to:
The CMI Work Plan is also available in hard copy for review at the following locations:
Environmental clean-up activity performed to address contamination resulting from hazardous waste treatment, storage and disposal facilities is referred to as "corrective action" in the hazardous waste regulations. Hazardous waste treatment, storage and disposal facilities are required to submit corrective action plans to EGLE for review and approval. The corrective action plans provide details on how the site owner(s) and/or operator(s) will investigate and clean-up the contamination to meet standards protective of human health and the environment. Though the corrective action cleanup process varies from site to site, it typically includes an initial site assessment, site characterization, interim actions, evaluation of remedial alternatives, and implementation of the selected remedy.
EGLE invites the community to comment on the CMI Work Plan. Comments can be submitted as follows:
Comments should include the name, address, and email of the writer; a concise statement of the basis for the comment(s); and the supporting relevant facts upon which the comment(s) are based. Written comments must be postmarked no later than June 16, 2023, the end of the comment period. If requested before June 1, 2023, EGLE will schedule a formal public hearing to take formal verbal comment on the proposed, conditional approval of the CMI Work Plan.
Before issuing a final decision, EGLE will evaluate all comments received. Information regarding EGLE’s final decision on the CMI Work Plan will be provided to all persons who submit timely formal comments or are on the facility mailing list. EGLE will respond to all significant comments on the CMI Work Plan, and explain any changes made in response to the comments received.
