This report summarizes and reviews the Institutional Controls (IC) program currently in place within British Columbia (BC). It also provides an overview of the IC programs within Ontario, Quebec, and selected United States jurisdictions. Finally, this report evaluates various options for the IC program amendments in BC.
The phrase "institutional controls" refers to legal or administrative mechanisms to restrict land use where, during or at the completion of site cleanup, residual contamination remains. In many cases, residual contamination remains at sites because potential exposures to site contamination, under anticipated future uses, does not demand a full cleanup. At these sites, safe reuse may occur even where some residual contamination remains.
Clean up standards at these future use-based cleanups often allow contamination to remain in place, if it will not pose an unacceptable risk in light of anticipated future land uses. For example, industrial use scenarios typically allow more lenient cleanup standards than, for example, residential use scenarios. And regardless of the type of anticipated land use, future use-based cleanups often rely on additional future use assumptions, such as, that groundwater will not be withdrawn from the site area or that excavation will not occur below, for example, fifteen feet.
