ATEX Express Ethane Pipeline Hits Potential Snag in Ohio

Enterprise Products Partners recently announced a 1,230 mile ethane pipeline from Pennsylvania to the Gulf Coast (see this MDN story). Dubbed the ATEX Express (Appalachia to Texas), the proposed pipeline includes building 353 miles of new pipeline through Ohio. But the Ohio stretch of construction has hit a potential snag.

Ohio Power Siting Board (OPSB) officials say Enterprise must get their approval before building it, but Enterprise disputes the OPSB has the authority to oversee construction the ATEX Express in the state. The dispute hinges on whether the natural gas liquid ethane that will flow through the pipeline is a liquid or a gas. Ethane under pressure is a liquid, but when it hits the air, it turns into a gas.
