(Radio Iowa) – A District Court Judge has ruled that an Iowa law allowing hazardous liquid pipeline companies to enter private land to conduct surveys is unconstitutional. The ruling came in a lawsuit by Navigator against a landowner who wouldn’t let surveyors onto his land near the northwest Iowa town of Sioux Rapids. Omaha-based Navigator wants to build a pipeline that would capture carbon dioxide from ethanol and fertilizer plants and send it to another location to be stored underground. Navigator and Summit Carbon Solutions of Iowa have sued landowners unwilling to allow surveyors onto their property. A Navigator spokesperson issued a statement saying the the company plans to appeal the ruling.
