HB 599 adds R.S. 30:961(L), which flatly says the law does not authorize sale of running surface water owned by Louisiana for use outside the state, and it repeals the existing subsection (I) that allowed the secretary to enter cooperative endeavor agreements (CEAs) for out-of-state withdrawals with legislative committee approval. In short: the state withdraws a delegated pathway for selling or otherwise contracting away running surface water for use beyond Louisiana’s borders.
That change matters for any public or private project that planned to move river or stream water across the state line—municipal bulk sales, private commercial exports, or multistate industrial supply arrangements. It also creates immediate legal and administrative questions about scope (what counts as a “sale” or as “running surface water”), existing agreements, and how agencies will enforce and implement the ban.
At a Glance
What It Does
The bill adds an express prohibition against selling running surface water owned by Louisiana for use outside the state and removes the statutory authority that let the secretary enter CEAs permitting out‑of‑state withdrawals. It does not create a new permitting program or set penalties; it removes one explicit authorization and inserts a prohibitory statement into R.S. 30:961.
Who It Affects
State agencies that negotiate water CEAs, utilities and private firms that contract for bulk surface water, and out‑of‑state entities seeking Louisiana water supplies are directly affected. Indirectly, local governments, environmental organizations, and industries dependent on river flows will see operational and planning impacts.
Why It Matters
The bill narrows the universe of lawful interstate surface water transfers and changes the legal footing for commercial water exports. Professionals in resource management, utilities, and project finance need to reassess contracts, permits, and risk models where out‑of‑state use of Louisiana surface water was part of a project plan.

What This Bill Actually Does
HB 599 inserts a single sentence into the Louisiana statutes to say that nothing in the running surface water law authorizes sale of that water for use outside Louisiana, and it deletes the prior subsection that specifically allowed the secretary to enter cooperative endeavor agreements for out‑of‑state use with legislative committee approval. Practically, the bill strips a statutory tool previously used to formalize multistate or cross‑border water arrangements.
The text limits its reach to "running surface water," the term already used in R.S. 30, which generally refers to moving waters such as rivers and streams rather than groundwater or static impoundments. Because the bill neither creates a substitute permit nor outlines penalties or enforcement mechanics, the immediate legal effect is prohibitory: state officials will lack the statutory authorization to cut CEAs that accomplish out‑of‑state sales or withdrawals of running surface water.The law leaves several practical matters unresolved.
It does not expressly rescind already‑executed CEAs or clarify whether transfers characterized as leases, service agreements, or in‑lieu exchanges count as prohibited "sales." Nor does it address transfers of water that transit Louisiana to a second state, transfers of treated water, or sales of water rights tied to impoundments. Those gaps will matter to agencies and private parties trying to interpret compliance obligations.For project planners and compliance officers, the takeaway is clear: any pending or proposed contract that contemplated a CEA or a direct sale of river or stream water for use outside Louisiana will face a new legal barrier.
Expect agencies to revise internal guidance and for affected parties to seek clarity via rulemaking, renegotiation, or, potentially, legislative carve‑outs for specific projects.
The Five Things You Need to Know
The bill adds R.S. 30:961(L) explicitly prohibiting the sale of running surface water owned by Louisiana for any use outside the state.
The bill repeals R.S. 30:961(I), which previously authorized the secretary to enter cooperative endeavor agreements for withdrawal of running surface water for out‑of‑state use with House and Senate natural resources committee approval.
The prohibition is limited to "running surface water" owned by the state—groundwater, private water rights, and non‑running water bodies are not addressed by the text.
HB 599 does not include grandfathering language or an express repeal of existing agreements, nor does it specify enforcement mechanisms or civil/criminal penalties for violations.
The bill leaves ambiguous whether arrangements characterized as leases, treated‑water sales, transit transfers, or multistep commercial agreements fall within the ban on "sale" for out‑of‑state use.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Express ban on sale of running surface water for out‑of‑state use
This new subsection inserts a categorical rule: nothing in the running surface water statute authorizes sale of running surface water owned by Louisiana for use outside the state. That language converts a permissive framework into a proscriptive one for cross‑border surface water sales. Practically, it removes a statutory justification state actors could cite when approving or negotiating a commercial transfer of river or stream water beyond Louisiana’s borders.
Removes the secretary’s CEA authority for out‑of‑state withdrawals
Subsection (I) used to allow the secretary to enter into cooperative endeavor agreements for out‑of‑state use, subject to approval by the House and Senate natural resources committees. Repealing that subsection strips the explicit legislative authorization for the secretary to execute CEAs that effectuate cross‑border withdrawals. Agencies will need to adjust internal policies and stop relying on that statutory pathway.
What the bill does not do — and why that matters
The statute focuses on "sale" of "running surface water" but does not define those terms or provide enforcement procedures, penalties, or transitional rules. It therefore creates immediate interpretive questions—whether in‑state transfers that later move out of state are covered, how to treat treated or bulk water that is transported, and whether existing CEAs remain valid. Those drafting gaps will be the fronts for administrative guidance, litigation, or follow‑up legislation.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Louisiana state policymakers and resource managers — they regain a clear, statutory basis to prevent outbound commercial sales of river and stream water, preserving political control over state surface water assets.
- In‑state water users (municipal utilities, in‑state industries, and agriculture) — they face reduced competition from out‑of‑state buyers for bulk surface water supplies, which can protect local access and pricing.
- Riverine ecosystems and environmental organizations — by blocking commercial exports of running surface water, the bill reduces a pressure pathway that can lower instream flows and harm habitat, making conservation outcomes easier to defend.
- Communities in source basins — local constituencies that rely on consistent flows for municipal supply, recreation, and industry get stronger statutory protection against projects that would divert surface water out of the basin.
Who Bears the Cost
- Out‑of‑state utilities, municipalities, and industrial users that had planned to secure Louisiana running surface water supplies — their prospective supply contracts and project economics are directly curtailed.
- Private water exporters, brokers, and investors who underwrite cross‑border bulk water transactions — prior business models premised on CEAs or sales to out‑of‑state users lose a statutory pathway.
- State agencies and the secretary — the repeal reallocates responsibilities, may require new guidance, and could create administrative workload as agencies process questions, update rules, and potentially negotiate alternatives.
- Projects and developers that built financial models assuming the ability to transfer surface water out of state — they face contract renegotiation risk and potential stranded investment costs.
Key Issues
The Core Tension
The central tension is between asserting state control to protect in‑state water supplies and the economic or cooperative benefits of cross‑border water transfers: the bill prioritizes preservation of running surface water within Louisiana, but in doing so it closes a statutory door that some projects, regional partnerships, or neighboring jurisdictions may have seen as a necessary route for water security or economic development.
The bill is tidy in wording but thin on mechanics. By prohibiting "sale" without defining the term, it leaves open whether other commercial arrangements—leases, service contracts for water treatment and transport, or arrangements where water is sold as a byproduct of a utility service—would be treated as forbidden sales.
Similarly, restricting the prohibition to "running surface water" sidesteps groundwater, impoundments, and treated effluent; those categories could become targets for workaround strategies, shifting extraction pressure rather than reducing total removals.
There's also legal friction at the margins. The statute removes a state authorization route but does not address existing CEAs: courts or agencies will need to decide whether those agreements survive, are unenforceable, or require legislative ratification.
Finally, enforcement and monitoring are unresolved—the bill contains no civil penalty scheme or explicit enforcement authority tied to the prohibition, so practical compliance may rely on administrative gatekeeping (permit denials, refusal to renew agreements) rather than a new enforcement regime.
