Ohio institutional and engineering controls lists

The Ohio Environmental Protection Agency (Ohio EPA) posts two lists of cleanup projects that rely on controls: a List of projects with Institutional Controls and a List of projects with Engineering Controls. Its Division of Environmental Response and Revitalization (DERR) posts both as spreadsheets beside the DERR database.

In a Phase I ESA

These lists are the Ohio form of the state institutional and engineering control records that ASTM E1527-21 lists as a standard source. The general reading of a control listing is on the State/Tribal Institutional and Engineering Control Registries page. Four Ohio details shape how to read one.

• Environmental covenants carry the restrictions. Ohio EPA says many cleanup plans include site controls put in place through legal documents, and that Ohio enacted an environmental covenants act in December 2004 (Ohio Revised Code 5301.80 to 5301.92) to ensure that institutional, or land use, controls can be implemented and enforced. Its template covenant subjects a property to activity and use limitations.
• A covenant not to sue can depend on it. Under the Voluntary Action Program, the state's covenant not to sue protects an owner only while the property is used and maintained in the same manner as when it was issued. Ohio EPA says these properties often restrict the occupancy of buildings because of vapor intrusion concerns, and that violating the conditions of the environmental covenant can void the covenant not to sue. Read the environmental covenant before any change of use or occupancy.
• Restrictions are reported on every year. A Voluntary Action Program property with use restrictions, which Ohio EPA also calls activity and use limitations or institutional controls, owes an annual compliance report. A property with an operation and maintenance plan or a risk mitigation plan must report on that as well. Ask for the latest reports.
• Other programs use controls too. Under the Remedial Response Program, Ohio EPA inspects remedies and says operation and maintenance may consist merely of ensuring that property use restrictions continue. RCRA corrective action remedies may combine removal and treatment with engineering and institutional controls. The page read does not say which programs the two lists draw on.

What the record shows

The page read does not describe the fields in either spreadsheet. When read, it gave their last update as June 25, 2026.

Where to look a site up

• Both lists are on Ohio EPA's Database Request page.
• For Voluntary Action Program properties, Ohio EPA's USD and CNS Site Summaries include remedies or land use restrictions.
• DERR is at 614-644-2924.

Getting the file

A listing says a control exists. The covenant or the plan says what it requires. The agency's eDocument search has a Covenant document type that runs from September 30, 2014. For anything else, use the online file review request form; Ohio EPA says the best first contact is the district office where the site is located.
