Couser v. Emmet County

The developer of an interstate carbon dioxide pipeline and a farmer and part-owner of an ethanol production facility challenged a county ordinance concerning pipeline permitting and safety. They argued that that ordinance was preempted by the federal Pipeline Safety Act and Iowa’s hazardous liquid pipelines and storage facilities statute. These plaintiffs <a href="https://climatecasechart.com/case/couser-v-story-county/">previously challenged</a> another county’s law regulating the pipeline.
