Institutional controls are defined by Minnesota Statute,
Section ยง 115B.02, subdivision 9a, as legally enforceable
restrictions, conditions, or controls on the use of real
property, ground water, or surface water located at or adjacent
to a facility where response actions are taken that are
reasonably required to assure that the response actions are
protective of public health or welfare or the environment.
Institutional controls include restrictions, conditions, or
controls enforceable by contract, easement, restrictive
covenant, statute, ordinance, or rule, including official
controls such as zoning, building codes, and official maps. An
affidavit required under section 115B.16, subdivision 2, or
similar notice of a release recorded with real property records
is also an institutional control.
