Illinois Compiled Statutes
Information maintained by the Legislative Reference Bureau
Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts
soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide
Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

(20 ILCS 3420/4)
(from Ch. 127, par. 133c24)
State agency undertakings.
(a) As early in the planning process as may be practicable and prior to
the approval of the final design or plan of any undertaking by a State
agency, or prior to the funding of any undertaking by a State agency, or
prior to an action of approval or entitlement of any private undertaking by
a State agency, written notice of the project shall be given to the
Director either by the State agency or the recipients of its funds, permits
or licenses. The State agency shall consult with the Director to determine
the documentation requirements necessary for identification and treatment
of historic resources. For the purposes of identification and evaluation
of historic resources, the Director may require archaeological and historic
investigations. Responsibility for notice and documentation may be
delegated by the State agency to a local or private designee.
(b) Within 30 days after receipt of complete and correct documentation
of a proposed undertaking, the Director shall review and comment to the
agency on the likelihood that the undertaking will have an adverse effect
on a historic resource. In the case of a private undertaking, the
Director shall, not later than 30 days following the receipt of an
application with complete documentation of the undertaking, either approve
that application allowing the undertaking to proceed or tender to the
applicant a written statement setting forth the reasons for the
requirement of an archaeological investigation. If there is no action
within 30 days after the filing of the application with the complete
documentation of the undertaking, the applicant may deem the application
approved and may proceed with the undertaking. Thereafter, all
requirements for archaeological investigations are waived under this Act.
(c) If the Director finds that an undertaking will adversely affect an
historic resource or is inconsistent with agency policies, the State agency
shall consult with the Director and shall discuss alternatives to the proposed
undertaking which could eliminate, minimize, or mitigate its adverse effect.
During the consultation process, the State agency shall explore
all feasible and prudent plans which eliminate, minimize, or mitigate
adverse effects on historic resources. Grantees, permittees, licensees, or
other parties in interest and representatives of national, State, and local
units of government and public and private organizations may participate
in the consultation process. The process may involve on-site inspections and
public informational meetings pursuant to regulations issued by the Department of Natural Resources.
(d) The State agency and the Director may agree that there is a feasible
and prudent alternative which eliminates, minimizes, or mitigates the
adverse effect of the undertaking. Upon such agreement, or if the State
agency and the Director agree that there are no feasible and prudent
alternatives which eliminate, minimize, or mitigate the adverse effect, the
Director shall prepare a Memorandum of Agreement describing the
alternatives or stating the finding. The State agency may proceed with the
undertaking once a Memorandum of Agreement has been signed by both the
State agency and the Director.
(e) After the consultation process, the Director and the State agency
may fail to agree on the existence of a feasible and prudent alternative
which would eliminate, minimize, or mitigate the adverse effect of the
undertaking on the historic resource. If no agreement is reached, the agency
shall call a public meeting in the county where the undertaking is proposed
within 60 days. If, within 14 days following conclusion of the public
meeting, the State agency and the Director fail to agree on a feasible and
prudent alternative, the proposed undertaking, with supporting
documentation, shall be submitted to the Historic Preservation
Mediation Committee. The document shall be sufficient to identify each
alternative considered by the Agency and the Director during the
consultation process and the reason for its rejection.
(f) The Mediation Committee shall consist of the Director and 5 persons
appointed by the Director for terms of 3 years each, each of whom shall be
no lower in rank than a division chief and each of whom shall represent a
different State agency. An agency that is a party to mediation shall be
notified of all hearings and deliberations and shall have the right to
participate in deliberations as a non-voting member of the Committee.
Within 30 days after submission of the proposed undertaking, the Committee
shall meet with the Director and the submitting agency to review each
alternative considered by the State agency and the Director and to evaluate
the existence of a feasible and prudent alternative. In the event that the
Director and the submitting agency continue to disagree, the Committee
shall provide a statement of findings or comments setting forth an
alternative to the proposed undertaking or stating the finding that there
is no feasible or prudent alternative. The State agency shall consider the
written comments of the Committee and shall respond in writing to the
Committee before proceeding with the undertaking.
(g) When an undertaking is being reviewed pursuant to Section 106 of the
National Historic Preservation Act of 1966, the procedures of this law
shall not apply and any review or comment by the Director on such undertaking
shall be within the framework or procedures of the federal law. This subsection shall not prevent the Department of Natural Resources from entering into an agreement with the Advisory
Council on Historic Preservation pursuant to Section 106 of the National
Historic Preservation Act to substitute this Act and its procedures for
procedures set forth in Council regulations found in 36 C.F.R. Part 800.7.
A State undertaking that is necessary to prevent an immediate and
imminent threat to life or property shall be exempt from the requirements
of this Act. Where possible, the Director shall be consulted in the
determination of the exemption. In all cases, the agency shall provide the
Director with a statement of the reasons for the exemption and shall have
an opportunity to comment on the exemption. The statement and the comments
of the Director shall be included in the annual report of the Department of Natural Resources as a guide to future actions. The provisions of this
Act do not apply to undertakings pursuant to the Illinois Oil and Gas Act,
the Surface-Mined Land Conservation and Reclamation Act and the Surface
Coal Mining Land Conservation and Reclamation Act.

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
(c) The Director shall not require archaeological investigations for
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.
