Statutory Review

The solar electric generation facility is a Type 3 action under Wis. Admin. Code § PSC 4.10(3).Type III actions normally do not require preparation of an EA or an environmental impact statement (EIS) under Wis. Admin. Code § PSC 4.10(3). However, an evaluation of a specific Type III proposal may indicate that the preparation of an EA is warranted for that proposal. The Commission will prepare an EA for this project that will evaluate the location of the project and its potential environmental, community, and private property impacts. There will be a preliminary determination when the EA is complete that will determine whether the preparation of an EIS is necessary. Comments on this preliminary determination will be accepted and considered before a final determination is made. At the time of the preliminary determination, the Commission shall make copies ofthe EA available to those persons that request it.
