Sec. 2.
Legislative intent

A. The legislature finds
and declares that there is at present and will continue to be a growing need
for electric service that will require the construction of major new
facilities. It is recognized that facilities cannot be built without
in some way affecting the physical environment where the facilities are
located. The legislature further finds that it is essential in the
public interest to minimize any adverse effect on the environment and on the
quality of life of the citizens of this state that new facilities might cause.�
The legislature further finds that present practices, proceedings and laws
relating to the location of utility facilities may be inadequate to protect
environmental values and take into account the total effect of the facilities
on society.� The lack of adequate statutory procedures may result in delays in
new construction and increases in costs that are eventually passed on to the
citizens of this state in the form of higher electric rates and that may result
in the possible inability of the electric suppliers to meet the needs and
desires of the citizens of this state for economical and reliable electric
service.� Furthermore, the legislature finds that existing law does not provide
adequate opportunity for individuals, groups interested in conservation and the
protection of the environment, local governments and other public bodies to
participate in a timely fashion in the decision to locate a specific major
facility at a specific site.

B. The legislature declares
that it is the purpose of this act to provide a single forum for the
expeditious resolution of all matters concerning the location of electric
generating plants and transmission lines in a single proceeding to which access
will be open to interested and affected individuals, groups, county and
municipal governments and other public bodies to enable them to participate in
these decisions.
