From DATCP
The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) prepares agricultural impact statements (AIS) for public projects that will involve acquiring farmland, through either outright purchase or easements.
A public project is one where the party in charge — the project initiator — has condemnation authority, also called eminent domain. Public projects include roads, airports, electric transmission lines, pipelines, parks and wastewater treatment plants. Project initiators include local governments, state agencies, and utilities.
