Sec. 1-6.

Definitions.

As used in this Act:

(a) "Wetland" means land that has a predominance of hydric soils (soils
which are usually wet and where there is little or no free oxygen) and that
is inundated or saturated by surface or groundwater at a frequency and
duration sufficient to support, and that under normal circumstances does
support, a prevalence of hydrophytic vegetation (plants typically found in
wet habitats) typically adapted for life in saturated soil conditions.
Areas which are restored or created as the result of mitigation or planned
construction projects and which function as a wetland are included within
this definition even when all three wetland parameters are not present.

(b) "Adverse wetland impacts" means any land management and construction
or related project activity which directly or indirectly reduces the size
of a wetland or impairs a wetland's functional value, as described in
subsection (c) of Section 1-2 of this Act, or the hydraulic and
hydrologic characteristics of a wetland.

(c) "Director" means the Director of Natural Resources.

(d) "Department" with reference to this Act means the Department of
Natural Resources.

(e) "Committee" means the Interagency Wetlands Committee created by this
Act.

(f) "Mitigation" includes avoiding, minimizing or compensating for
adverse wetland impacts.  This includes:

(1) Avoiding the impact altogether by not taking a certain action or parts
of an action;

(2) Minimizing the impact by limiting the magnitude of the action; and

(3) Compensating for the impact by replacing or providing substitute wetland resources
