Review of private undertakings.
(a) The Department shall adopt standards, including maps, in
accordance with the Illinois Administrative Procedure Act, for determining
whether a private undertaking will affect a high probability area for the
statewide occurrence of archaeological resources. The Illinois State
Museum shall propose to the Department maps of high probability areas for
each county in the State that the Department shall consider in creating its
standards. The maps shall be made available to any interested person and
shall be filed with all regional planning commissions to assist in the planning process.
(b) High probability area maps for each county in the State shall be
prepared by the Illinois State Museum and submitted to the Department.
Until maps for a particular county are adopted by the Department as rule,
the Director's review within that county
for archaeological resources shall
be limited to determining whether there are known archaeological sites
within the area of the undertaking. If there are no known sites, the
Director shall so notify the State agency or the local or private
designee responsible for the private undertaking and the undertaking may
proceed. If there is a known archaeological site within the undertaking,
the Director shall so notify the state agency or the local or private
designee responsible for the private undertaking and may require additional

private undertakings outside high probability areas unless the undertaking
may affect a known archaeological site. An archaeological investigation
may be required only on that portion of property within a high probability
area or where a known site exists on that property. Archaeological
investigations shall be required in high probability areas unless the
Director indicates that such investigations are not necessary.
