This bill enacts a single statutory pronouncement: the United States Fish and Wildlife Service final rule entitled “Endangered and Threatened Wildlife and Plants; Endangered Species Status With Critical Habitat for Guadalupe Fatmucket, Texas Fatmucket, Guadalupe Orb, Texas Pimpleback, Balcones Spike, and False Spike, and Threatened Species Status With Section 4(d) Rule and Critical Habitat for Texas Fawnsfoot” (89 Fed. Reg. 48034; June 4, 2024) shall have no force or effect.
In short, the bill would strip the legal force from that rule and remove the regulatory basis for the listings and critical‑habitat designations set out in it.
That action matters because a statutory nullification of an agency rule short‑circuits the ordinary administrative process and immediately alters the legal framework that governs federal consultations, permitting, and criminal/take prohibitions tied to the Endangered Species Act designations. The change would affect federal, state, and private projects in the watersheds where those mussels occur and raise practical and legal questions the bill does not address, including the status of ongoing consultations, prior enforcement actions, and whether the agency must re‑examine the species using its scientific record.
At a Glance
What It Does
The bill declares that the specified USFWS final rule (89 Fed. Reg. 48034, June 4, 2024) has no legal effect. By statute it removes the regulatory basis for the listings and critical‑habitat designations contained in that rule without directing any further agency action.
Who It Affects
Federal agencies that rely on ESA listings and critical habitat for Section 7 consultations (for example, USFWS, Army Corps of Engineers) and project proponents in affected Texas river systems — including water districts, agricultural irrigators, infrastructure developers, and energy companies. Conservation organizations, researchers, and entities that previously relied on the rule for protections are also directly affected.
Why It Matters
Congressional nullification of a specific regulatory listing is an uncommon and decisive intervention into the ESA process: it alters compliance obligations overnight and creates implementation questions the bill does not resolve, from pending consultations to the legal status of actions that occurred while the rule was in force.

What This Bill Actually Does
The bill is extremely short and does one thing: it declares by statute that the USFWS final rule published at 89 Fed. Reg. 48034 on June 4, 2024 has no force or effect.
That final rule had established endangered species status and critical habitat for six mussel species (Guadalupe Fatmucket, Texas Fatmucket, Guadalupe Orb, Texas Pimpleback, Balcones Spike, and False Spike) and given threatened status with a Section 4(d) rule and critical habitat for the Texas Fawnsfoot. Removing the rule would eliminate the legal designations and the regulatory provisions tied to that specific Federal Register action.
Because the bill does not instruct the agency to take any follow‑up steps, it leaves practical implementation to the receiving agencies and courts. Federal permitting agencies that used the rule as the basis for Section 7 consultations would lose that regulatory hook; project proponents could argue that ongoing consultations must be revised or terminated.
The bill also says nothing about prior permits, biological opinions already issued, enforcement actions taken while the rule was in force, or whether any interim protections remain under other authorities.The statute does not create new standards, reassign listing determinations, or appropriate funds. It also does not specify an effective date beyond the normal rule that statutes take effect on enactment, nor does it include a savings clause preserving actions already taken under the rule.
Those omissions create immediate legal and operational ambiguity for agencies, regulated parties, and conservation entities about how to treat prior decisions and how to proceed if new petitions or listings are later considered.
The Five Things You Need to Know
The bill covers one specific USFWS final rule: 89 Fed. Reg. 48034 (published June 4, 2024) concerning six mussel species and one threatened mussel in Texas.
Statutory effect: the bill declares that rule “shall have no force or effect,” thereby removing the rule’s legal authority without directing new agency proceedings.
The bill contains a single substantive section and includes no savings clause preserving prior actions taken under the now‑voided rule.
The text does not appropriate funds or require the Fish and Wildlife Service to relist the species or undertake any new administrative process.
Because the bill nullifies a final rule rather than amending the ESA, it changes regulatory obligations directly by statute instead of through the agency’s rulemaking record.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Statutory nullification of a named USFWS final rule
This is the operative clause: it names the full title of the USFWS final rule and declares it to have no force or effect. Mechanically, the clause strips the regulatory content of that Federal Register entry from the Code of Federal Regulations and rescinds the legal status the rule created (the listings and critical‑habitat designations) by statute rather than by agency action.
Targeting a single Federal Register action
The bill references the exact Federal Register citation and publication date, so its scope is narrowly framed to that particular rule text rather than to a broader set of regulatory provisions or to the Endangered Species Act itself. That precision makes clear what is rescinded, but it also means the bill does not address any related regulatory instruments or administrative records that preceded or followed that Federal Register notice.
What the statute does not do — and why that matters
The statute does not include transitional or savings language, it does not instruct the agency to take additional steps (for example, to re‑open a review or reissue a notice), and it does not address the legal status of agency actions taken while the rule was in force. Those omissions generate immediate legal questions about the handling of existing biological opinions, permits, or enforcement actions and leave it to agencies and courts to interpret the practical consequences.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Private landowners and developers in affected Texas watersheds — they would no longer face project constraints tied specifically to the listings and critical habitat designated in the rescinded rule, which can reduce permitting delays and mitigation obligations.
- State and local water managers (river authorities, irrigation districts) — rescission removes a federal regulatory layer that commonly triggers consultations and potential operational constraints on water draws tied to ESA protections.
- Infrastructure and energy project proponents (transportation, oil and gas, utility relocation) — projects that had routed or been modified to avoid designated critical habitat could avoid or reduce compliance costs tied to that specific rule.
- Entities that challenged the rule or opposed the listing (including some industry trade groups and state governments) — Congress’s action would obviate the need for continued litigation over that final rule.
Who Bears the Cost
- Conservation organizations, researchers, and public‑interest advocates — they lose the protections the rule created and must decide whether to pursue litigation, new petitions, or other advocacy to restore safeguards for the species.
- The six mussel species and Texas Fawnsfoot — nullification removes regulatory protections intended to reduce extinction risk, potentially increasing vulnerability if no other protections apply.
- Federal agencies and permitting authorities (USFWS, Army Corps of Engineers) — they face operational and legal ambiguity about how to treat pending consultations, biological opinions, and enforcement actions made under the rescinded rule.
- State agencies and municipalities that relied on the listing for conservation planning — they may face reputational and planning costs if species declines accelerate or if federal funding and partnerships shift as a result.
Key Issues
The Core Tension
The central dilemma is between decisive, immediate relief for economic actors and the procedural‑scientific integrity of species protection: the bill delivers rapid regulatory clarity for projects and landowners by statutorily voiding a listing, but it does so without substituting an administrative process or scientific reassessment, leaving species conservation and legal certainty in tension.
Two implementation challenges dominate. First, the bill eliminates the rule but says nothing about actions already taken under it — for example, biological opinions, formal consultations, permits conditioned on avoiding critical habitat, or mitigation commitments.
Courts and agencies will need to decide whether those past administrative acts survive the statutory rescission, which could trigger litigation and operational disruption. Second, the bill replaces an administrative, science‑based decision with a statute that does not engage the agency’s record or specify a scientific alternative; that raises practical questions about how future listings or protections should proceed for these species and how to reconcile statutory repeal with the ESA’s conservation goals.
Beyond implementation, the bill illustrates an institutional trade‑off: Congress can precisely remove a regulatory constraint, but doing so without procedural scaffolding (no savings clause, no directive to the agency) shifts uncertainty to agencies, regulated parties, and courts. The absence of funding or direction for supplemental scientific review means the pathway to restoring protections — if desired later — would require either new agency proceedings or additional legislative action, each of which has its own procedural and evidentiary burdens.
