Cessation of Regulated Operations (CRO)

The goal of the Cessation of Regulated Operations (CRO) program is to prevent threats to human health and the environment that are created when business owners and operators irresponsibly abandon businesses where chemicals were produced, used, stored or handled. In 1987, vandals entered the closed Dayton Tire & Rubber facility to remove copper cores from several large transformers remaining at the facility. This vandalism resulted in the discharge of Askerol (PCB oil) from the transformers to Wolf Creek. Cleaning up and demolishing the site took three years and cost approximately $8 million. This incident and many others prompted State Representative Thomas Roberts to introduce House Bill (HB) 98. This law (Ohio Revised Code (ORC) Chapter 3752) went into effect July 1, 1996, when Ohio created the Cessation of Regulated Operations (CRO) program.

ORC Chapter 3752 applies to owners or operators of facilities required to file a chemical inventory report under the Emergency Planning and Community Right-to-Know Act (EPCRA). Facilities exempted from CRO include: underground storage tanks regulated by the State Fire Marshal’s Bureau of Underground Storage Tank Regulations (BUSTR); oil/gas production operations; and public utilities.
