midwest regulations on CO2 pipelines

The rules for CO2 pipelines in Iowa, Illinois, Minnesota, Nebraska and the Dakotas would require:  carbon steel pipe ranging from 4 to 24 inches in diameter with operating pressures of up to 2,200 pounds per square inch. That stays the same across these states. What varies across the states is how to go about building the pipelines. NE has no rules. IA has a lot of rules. Some counties along the way have stricter rules concerning eminent domain.
