EAST HELENA INSTITUTIONAL CONTROLS PROGRAM
Institutional Controls
The U.S Environmental Protection Agency's September 2009 East Helena Superfund Site Operable Unit (OU) 2 Residential and Undeveloped Lands Final Record of Decision (ROD) recognizes that residual levels of lead and other contaminants will remain in place (sometimes at levels that pose health risks) beneath foundations, sidewalks and temporary structures, in unfinished basements or attics, and on undeveloped lands in and around East Helena. For this reason, the ROD concluded that Institutional Controls (ICs) are an important and necessary component of the final remedial action for the East Helena Superfund Site (former site of the Asarco lead smelter).
ICs are administrative or legal controls intended to help return a site to safe and productive uses by minimizing the potential for human exposure to contamination and protecting the integrity of the selected remedy (like the soil removals that have occurred in our community).
ICs protect human health and the environment by restricting property activity, use, or access. ICs also provide information to modify behavior by making the public aware of soil contamination concerns and restricted uses on properties.
