Louisiana Attorney General Liz Murrill has escalated a contentious regulatory battle, urging a state court to halt the Louisiana Public Service Commission’s oversight of the Rosefield Fourchon oil terminal. This high-stakes legal challenge centers on a critical interpretation of state law regarding what constitutes “pipeline transportation” versus internal storage operations, with profound implications for energy infrastructure investment and regulatory precedents in Louisiana.
Louisiana Attorney General Liz Murrill has taken a firm stance against what she views as an overreach by the Louisiana Public Service Commission (LPSC), filing a brief in the 19th Judicial District Court to stop the commission’s regulation of oil terminal operator Rosefield Fourchon. This legal maneuver highlights a fundamental disagreement over statutory interpretation and the scope of state regulatory power, directly impacting how oil storage and movement are classified within Louisiana.
The Core of the Dispute: Storage vs. Pipeline Transportation
At the heart of Murrill’s argument is the assertion that the LPSC’s ruling misreads state law, particularly amendments passed by lawmakers in the spring of 2025. These amendments aimed to clarify that “de minimis movement of oil wholly within a tank facility or storage terminal does not rise to the level of ‘the transportation of petroleum.’” Murrill contends that classifying Rosefield Fourchon, primarily a storage and metering facility, as a “common carrier” like airlines or railroads is an erroneous application of the law.
The case began with an accusation from Cantium, another producer utilizing Port Fourchon infrastructure, claiming Rosefield was overcharging at its terminal without a legally required LPSC-approved tariff. An administrative law judge initially sided with Cantium in December, a decision affirmed by the LPSC in May. Rosefield, supported by Murrill, vehemently rejects this premise, maintaining its operations are strictly confined to storage and metering, thus falling outside the commission’s jurisdiction.
Federal Regulators Weigh In: A Consistent Stance
Adding weight to Murrill’s position, federal regulators have echoed a similar sentiment regarding their authority. The Federal Energy Regulatory Commission (FERC) previously concluded that Rosefield’s Fourchon services “do not provide pipeline services.” FERC’s determination emphasized that crude oil moves intrastate after leaving the facility, effectively breaking the chain of interstate transportation that would typically trigger federal oversight. This federal perspective lends credence to the argument that Rosefield’s internal operations should not be subject to common carrier regulations.
The distinction is critical because common carrier status imposes stringent requirements, including LPSC approval of tariffs and rates. For instance, the article details that while FERC-approved rates were 67 cents per barrel in September 2023, Cantium claims Rosefield increased its charge to $2.50 that month without LPSC approval, and then to $4.87 per barrel in July of the current year. Cantium estimates overcharges since September 2023 at over $10 million for its volumes, while Rosefield asserts the LPSC has no jurisdiction over these “market rates.”
Legislative Intent and Economic Impact
Murrill’s brief highlights the 2025 legislative session amendments to La. R.S. 45:251, which she says were intended to explicitly exclude minimal, on-site oil movement within storage terminals from the definition of “transportation of petroleum.” This clarification, according to Murrill and Rosefield, should prevent the LPSC from asserting jurisdiction.

The implications of this regulatory battle extend beyond Rosefield Fourchon. Industry groups, including the Mid-Continent Oil and Gas Association and the International Liquid Terminals Association, have warned commissioners that treating terminal operators as common carriers would create significant hurdles. These include new registration and tariff requirements, mandatory commission approval of fees, and additional supervision fees to the Department of Revenue. Such increased regulatory oversight, they argue, would place Louisiana at a “distinct disadvantage,” potentially discouraging new investment and slowing critical modernization projects in the state’s vital energy sector.
The Legal Road Ahead for State Regulatory Power
Murrill’s request for an expedited stay underscores the urgency of the matter, citing state Supreme Court precedent that places questions of statutory interpretation within the district court’s original jurisdiction. The LPSC has the matter on its docket for October 23, awaiting action on Rosefield’s appeal and Murrill’s request to swiftly intervene.
This case is a stark example of the ongoing tension between legislative intent, regulatory interpretation, and industry concerns over economic viability. The outcome will not only determine the operational framework for Rosefield Fourchon but will also set a crucial precedent for the regulation of other oil storage and terminal facilities across Louisiana, impacting the state’s competitive edge in the energy market. Understanding the nuances of regulatory bodies like the Louisiana Public Service Commission is vital for the state’s economic landscape, and further information can often be found on the LPSC official website.
