Indiana's Department of Environmental Management (IDEM) Office of Land Quality uses a system of risk-based closure to address releases of hazardous substances or petroleum. When contamination remains on site, a legal or administrative measure called an Institutional Control (IC) may be needed. An IC protects human health and the environment by restricting property activity, use, or access to minimize exposure to contamination.
The IDEM Institutional Controls Registry is a listing of sites with ICs, sorted by county. There are two IC Registry summary reports available:
The IC Registry includes information such as the site address, county, city, IDEM cleanup program overseeing the project, and the types of land use restrictions applicable for the site. The registry also has interactive features including a link to view the actual IC document using IDEM’s Virtual File Cabinet, and, where available, Internet mapping technology for an aerial view of the site.
