A bipartisan crew of Gulf Coast lawmakers is taking another run at reshaping who calls the shots just off the shoreline. Their Offshore Parity Act would expand Louisiana, Mississippi and Alabama’s state waters from the current three nautical miles to roughly nine nautical miles. If Congress signs off, the move would hand those states new authority over future offshore oil, gas, mineral and permanent carbon-storage leases and redirect the resulting revenues, a prospect that has already drawn caution flags from federal agencies even as offshore leasing heats up.
What the bill would do
The Offshore Parity Act would amend the Outer Continental Shelf Lands Act and the Magnuson-Stevens Fishery Conservation and Management Act to carve out an “expanded submerged lands” band from three geographical miles out to three marine leagues, or about nine nautical miles. It would also let a state ask the Secretary of the Interior to delegate leasing authority within that zone. According to the House.gov text, any existing federal leases that fall into the newly expanded area would stay under current federal revenue-sharing rules, while new leases issued by a state under delegated authority would generate revenues that the state keeps under the bill’s framework.
Supporters say it levels the playing field
Backers led by Rep. Mike Ezell argue the proposal fixes a decades-old imbalance with Texas and parts of Florida and shifts more control back to coastal communities that live with the day-to-day impacts of offshore development. In a press release, Ezell and his co-sponsors framed the measure as both a fairness correction and an economic opportunity play, and local fishing officials told lawmakers that a wider state zone could cut down on the need for federal permits for shrimpers and charter operators. Supporters’ statements and testimony are laid out in Rep. Ezell’s release and in local reporting.
Interior flags practical and fiscal hurdles
The Department of the Interior, in a written statement submitted for a committee hearing, called the proposal a “significant change” to how OCSLA works today and warned that it raises knotty administrative and jurisdictional questions. Interior pointed out that shifting authority would also mean shifting responsibility for decommissioning more than 500 offshore structures and roughly 1,800 wells, a move the department said “could shift an estimated minimum of $2.5 billion in associated liabilities to the participating states.” In its filing, House.gov captured Interior’s recommendation that lawmakers spell out how any transition would work and how the dollars would truly shake out before advancing the bill.
Leases, dollars and timing
At its core, the bill would reshuffle who writes the leasing rules and who collects bonuses, rents and royalties for new tracts in the expanded zone. Supporters say that means more cash landing in state budgets. Critics warn it would dent federal revenues and add new layers of complexity to existing revenue-sharing arrangements.
As reported by New Orleans CityBusiness, advocates are hoping to lock in a full committee markup before the summer recess. The timing is tight. The Bureau of Ocean Energy Management has already scheduled an August 12 lease sale that would put roughly 80.4 million acres of the Gulf on the auction block. Details on that sale are outlined in BOEM’s notice.
The fight is unfolding as states look for their own offshore deal-making power. The Texas General Land Office last year executed a roughly 271,000-acre state lease with ExxonMobil for offshore carbon storage, a project supporters hold up as a model of state-led development. That agreement is described in a release from the Texas GLO.
Legal backdrop
Congress tried to sort out who owns what in the Gulf with the Submerged Lands Act of 1953, but Louisiana’s push for a broader “historic title” zone eventually ran into a wall at the Supreme Court. In United States v. Louisiana (1969), the court rejected those claims, which is the legal landscape the Offshore Parity Act now aims to revise by statute. That decision remains the key precedent explaining why Gulf states do not all have the same seaward limits. The ruling is archived at Justia.
Next steps
The measure has already gotten a public airing in a subcommittee hearing and is now waiting in line for a full committee markup date, with backers eyeing the summer work period. Even if Congress passes it, the bill would only allow a state to assume delegated leasing authority if the state formally applies and the Interior secretary decides that the state is capable of handling leasing and safety oversight. That means any real-world transfer of power would roll out over months or years, not overnight.
From New Orleans out to the Mississippi coast, the debate lands close to home. The underlying questions are blunt: who writes the rules in nearshore waters, who gets stuck with cleanup and decommissioning costs, and who ultimately collects when new offshore projects win approval. Those are the stakes that lawmakers, federal agencies and industry players are wrestling with as the Gulf’s leasing calendar and state ambitions collide just off the beach.
