AB 43 lets California add rivers to state wild and scenic system if federal protections are removed

Gives the California secretary authority to hold hearings and add federally delisted or exempted rivers to the state system, with strict limits on scope and duration.

The Brief

AB 43 requires the California secretary (Natural Resources) to hold a public hearing and consider adding any river or river segment in California to the state wild and scenic rivers system if the federal government removes, delists, or exempts that river from protections under the National Wild and Scenic Rivers System. The statute directs the secretary to classify added rivers as wild, scenic, or recreational and to take whatever administrative steps are necessary to complete the addition.

The bill places important limits on state action: added segments cannot exceed the geographic length specified in the prior federal designation, the state may not provide protections beyond what the federal designation formerly provided, and additions take effect immediately but remain subject to legislative modification. Those constraints and the immediate-effect rule create a fast state backstop to federal rollbacks while preserving legislative and legal guardrails.

At a Glance

What It Does

When the federal government delists, removes, or exempts a California river from protections under 16 U.S.C. §1278(a) (as of Jan 1, 2018), the bill requires the state secretary to hold a public hearing and, if in the state's interest, add and classify that river into California's wild and scenic rivers system. The secretary must carry out the administrative steps to add and classify the river but may not extend protection beyond the prior federal designation or increase its geographic scope.

Who It Affects

This affects the California Natural Resources Agency (the secretary), state park and river managers, federal agencies that oversee river designations and water projects, water-resources project sponsors, local governments near affected rivers, conservation organizations, and recreation and tourism businesses tied to river corridors.

Why It Matters

AB 43 creates an automatic state mechanism to preserve river protections when the federal government withdraws them, reducing the risk that a federal rollback immediately strips all protection. It also sets precedents for state-level backstops to federal environmental designations while deliberately constraining how far the state can go.

What This Bill Actually Does

AB 43 responds to a narrow but growing problem: when Congress or the president removes, delists, or exempts a river in California from the National Wild and Scenic Rivers System, the practical protections that the federal designation provided can disappear overnight. The bill gives the state secretary a checklist: hold a public hearing to gather information and comment, then decide whether state protection is warranted.

If the secretary decides to act, the statute requires adding the river to California’s state wild and scenic system and classifying it as wild, scenic, or recreational. It also requires the secretary to ‘take all actions necessary’ to complete that administrative addition.

The bill’s triggers are specific. One trigger is a federal statute that would require removal or delisting upon enactment.

The other is a secretary determination that a federal statute or executive order has exempted the river from the core federal restriction in 16 U.S.C. §1278(a) as that provision read on January 1, 2018. That second trigger is judgment-based: it depends on the secretary’s interpretation of whether a federal action effectively exempts a river from the federal restrictions that protect river values.AB 43 imposes tight limits on state additions.

A state designation cannot exceed the geographic length established by the former federal designation; the state cannot impose protections beyond the scope of the prior federal designation; it cannot conflict with the earlier federal classification or a Comprehensive River Management Plan. Additions take effect immediately on designation and remain in force unless and until the Legislature enacts a statute to remove, modify, or reclassify the river.

Finally, the bill expressly says nothing in it creates protections beyond those that the river previously had at the federal level.Operationally, the statute treats an addition made under this authority as if the river had been designated pursuant to the usual state statutory pathways (cross-referenced to Sections 5093.54 and 5093.545). That gives added rivers the same legal posture as other state-designated wild and scenic rivers, subject to the bill’s constraints and the Legislature’s subsequent power to change the designation.

The Five Things You Need to Know

1

The bill requires the secretary to hold a public hearing before deciding whether to add a federally delisted or exempted river segment to the state wild and scenic system.

2

If the secretary decides to add a river, the river is classified (wild, scenic, or recreational) and the secretary must take all administrative steps necessary to effect that addition.

3

Any state addition is capped at the geographic length specified in the prior federal designation and may not provide protections that exceed the prior federal scope.

4

Additions become effective immediately upon the secretary’s designation and remain in effect until the Legislature enacts a statute to remove, modify, or reclassify them.

5

One trigger for state action is the secretary’s determination that a federal statute or executive order has exempted a river from protections under 16 U.S.C. §1278(a) as it read on January 1, 2018.

Section-by-Section Breakdown

Section 5093.71(a)(1)

Trigger: federal removal or delisting

This subsection creates a bright-line trigger: if a federal statute would, on enactment, require removal or delisting of a California river from the national Wild and Scenic Rivers System, the state secretary must hold a public hearing and consider state-level designation. Practically, this means Congress-driven delistings are an automatic prompt for state review and possible action.

Section 5093.71(a)(2)

Trigger: federal exemption and secretary’s determination

This provision captures cases where the federal government exempts a river from the protections of 16 U.S.C. §1278(a), either by statute or executive order. The statute leaves the determination of exemption to the California secretary, making the finding an administrative decision rather than an automatic legal conclusion—an important operational detail that gives the state discretion but opens the door to interpretive dispute.

Section 5093.71(a)(2)(A)-(B)

Secretary must hold hearing and may add and classify

After the hearing, the secretary must weigh the public information and determine whether state protection is in California’s interest. If the secretary decides to add the river, the bill requires classifying it as wild, scenic, or recreational and treating that addition as if it were designated and classified under the normal state statutory provisions (5093.54 and 5093.545). The secretary is also charged with taking all administrative steps necessary to make the addition effective.

Section 5093.71(a)(2)(C)-(D)

Scope limits: geography, protections, and management plans

The statute caps additions at the federal designation’s geographic length and forbids state protections that exceed the prior federal scope or that conflict with the prior federal designation or any Comprehensive River Management Plan. Those clauses constrain the state’s ability to expand boundaries or impose stricter terms than the original federal designation provided.

Sections 5093.71(b)-(d)

Immediate effect, legislative override, and no extra protections

Designations under this section take effect immediately and stay in force until the Legislature enacts a statute to change them. Subdivision (d) restates that nothing in AB 43 should be read to grant protections beyond those that the river had under the National System before the federal removal or exemption—affirming both the bill’s intent to preserve prior protection and its reluctance to create a new, broader state standard.

Who Benefits and Who Bears the Cost

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.

Who Benefits

  • River conservation organizations: They gain a quicker state pathway to restore statutory protection for rivers that lose federal status, reducing the window of legal vulnerability after federal rollbacks.
  • Local communities and recreation businesses along affected rivers: Immediate state designation preserves protective measures that support tourism, fisheries, and local land-use stability that could otherwise be lost with a federal delisting.
  • California Natural Resources Agency and state river managers: They receive a clear statutory mechanism to retain and manage protections without waiting for lengthy legislative processes, enabling continuity in stewardship.

Who Bears the Cost

  • State Natural Resources Agency/Secretary staff: The agency must convene hearings, perform legal and factual analyses, and complete administrative additions—tasks that require staff time and possibly new funding.
  • Water-resources project proponents and infrastructure developers: Projects that relied on a federal delisting or exemption may face reimposed state protections suddenly, raising permitting complexity and potential redesign or mitigation costs.
  • Local governments and private landowners adjacent to added segments: Immediate state designation can introduce new land-use constraints or procedural requirements that were not anticipated after a federal change, creating compliance and economic impacts.

Key Issues

The Core Tension

The bill balances two legitimate goals—swiftly restoring protections lost at the federal level and avoiding an unchecked expansion of state authority—by empowering an executive official to act quickly but restricting the scope of that action; the core dilemma is whether speed with constrained scope produces real protection for river values or merely creates procedural formality that leaves substantive management gaps and legal uncertainty.

AB 43 tries to thread a narrow needle: it empowers rapid state action while simultaneously circumscribing how far that action can go. That creates several practical tensions.

First, the bill leaves an important category—the secretary’s determination that a federal statute or executive order 'exempts' a river from 16 U.S.C. §1278(a)—to administrative judgment. That discretion is necessary to act quickly but invites litigation over whether a federal action actually removed the operative federal restriction.

Expect disputes over statutory construction and the interpretation of executive orders. Second, although the bill prevents the state from imposing protections that exceed the prior federal scope, it does not specify enforcement mechanisms or how state rules will interact with federal requirements in practice.

State protections may mirror federal language but still change on-the-ground outcomes because enforcement, permitting, and remedies differ between jurisdictions.

Operationally, the immediate-effect clause is both the bill’s strength and its complication. It preserves protection without legislative delay, but it also imposes sudden constraints on ongoing projects and local planning.

The statute provides no funding for the administrative work required to hold hearings and execute designations, nor does it set a timeline for the secretary’s decision after the hearing. Finally, the cross-reference to Comprehensive River Management Plans assumes that such plans exist and are up to date; where plans are stale or absent, the prohibition on conflicts may create ambiguity about allowable state actions and fuel additional disputes with stakeholders and tribes.
