ARTICLE III. STATE WETLAND MITIGATION POLICY

    (20 ILCS 830/3-1) (from Ch. 96 1/2, par. 9703-1)
    Sec. 3-1. State Wetland Mitigation Policy. This Act implements the State Wetland Mitigation Policy, which directs that each State agency shall preserve wetlands as a priority of action when they develop construction or land management plans. When an agency can establish that no other feasible alternative exists and adverse wetland impacts are unavoidable, adverse impacts are to be compensated for through the development and implementation of a Department approved Wetland Compensation Plan.
    The policy requires progressive levels of compensation based upon the level of impact to the existing wetland and the location of compensation wetlands. Priority shall be given to locating compensation wetlands close to the wetland area impacted.
    Proposed State and State-supported construction activities which may impact wetlands identified on the Illinois Natural Areas Inventory, under public ownership or which provide habitat for State or federally threatened or endangered species will continue to require direct consultation with the Department and compliance with the Endangered Species Protection Act of 1986.

    (20 ILCS 830/3-2) (from Ch. 96 1/2, par. 9703-2)
    Sec. 3-2. Ownership and management. Wetlands, whether purchased, restored or created as the result of this Act shall be protected through either easements or fee simple transfer to either a public conservation agency or private conservation organization which will protect and manage the area.

    (20 ILCS 830/3-3) (from Ch. 96 1/2, par. 9703-3)
    Sec. 3-3. Wetland Compensation Account. Each State agency is hereby authorized to establish a Wetland Compensation Account to reconcile debits and credits established as the result of Wetland Compensation Plans.
    Management of a Wetland Compensation Account, if established, is the responsibility of the individual State agency. The Department shall review each agency's Compensation Account to confirm that all debits and credits are accounted for and balanced.

    (20 ILCS 830/3-4) (from Ch. 96 1/2, par. 9703-4)
    Sec. 3-4. Impact evaluation. For each project action involving a wetland, State agencies shall follow a multi-step process to avoid and minimize adverse wetland impacts as the preferred course of action. An agency must document that no other feasible alternative exists before adverse impacts are considered.
    In order of priority, these steps shall include:
    (1) The avoidance of adverse wetland impacts;
    (2) Minimal alteration with compensation on the site of the proposed project;
    (3) Significant alteration with compensation on the site of the proposed project;
    (4) Wetland destruction with compensation on the site of the proposed project;
    (5) Wetland destruction with compensation off the site of the proposed project but within the same drainage basin; and
    (6) Wetland destruction with compensation both off the site of the proposed project and out of the drainage basin.

    (20 ILCS 830/3-5) (from Ch. 96 1/2, par. 9703-5)
    Sec. 3-5. Value. Value shall include:
    Value for each compensation plan shall be established by the agency developing the compensation plan in consultation with the Department.

    (20 ILCS 830/3-6) (from Ch. 96 1/2, par. 9703-6)
    Sec. 3-6. Compensation ratios. Wetland Compensation Plans must adhere to a schedule of increasing compensation ratios based upon the amount of adverse wetland impact and the location of compensation projects.
    (a) Compensation ratios are required to:
    (1) Ensure that wetland systems are not destroyed without careful evaluation of other alternatives; and
    (2) Discourage destruction of wetland resources in rapidly developing areas of Illinois and their replacement within other regions of the State.
    (b) Compensation ratios shall be established and shall be progressively higher to reflect the priority actions identified in Section 3-4.
    The lowest compensation ratio shall be for minimal alteration and compensation on-site. The highest compensation ratio shall be for destruction and compensation outside the impacted wetland's drainage basin.
    Progressively higher compensation ratios shall strongly encourage agencies to avoid or minimize adverse wetland impacts and to compensate on-site.
    (c) Compensation may be accomplished through a combination of creation of new wetlands, restoration of degraded wetlands, acquisition of existing wetlands, or research. Compensation shall be accomplished using the best available technology.
    (d) The Department, through the Interagency Wetlands Committee, shall review the compensation ratios to determine their adequacy and appropriateness, and shall report the results of this review in the biennial report required in Section 2-1.
    (e) When adverse wetland impacts occur, the Wetland Compensation Plan must include the creation of at least one-for-one replacement of new wetlands of comparable functional type and size, before restoration, acquisition or research alternatives are considered.
    One provision of a Wetland Compensation Plan may include funding for needed research on wetland functions, restoration or creation. Credit for research funding requires approval of the Department upon consultation of the Committee.
