The CLEAN–UP Act authorizes the Secretary of the Army, acting through the Chief of Engineers, to carry out specified water resources projects that remove or remediate contaminated sediment under a joint remediation plan developed with the non‑Federal sponsor and approved by the EPA Administrator. When the Corps follows an EPA‑approved joint plan, the bill bars CERCLA liability for releases that result from the covered activity; it also preserves the federal government’s right to seek cost recovery from responsible parties.
This changes the default liability posture for Corps‑led sediment remediation tied to Congressionally authorized projects and activities under Water Resources Development Act (WRDA) section 312(f). The bill formalizes plan contents and public consultation requirements, allocates roles and funding identification, and gives EPA discretionary authority to add conditions — a package that will affect project timelines, sponsor responsibilities, interagency review workloads, and the practical enforcement of the polluter‑pays principle.
At a Glance
What It Does
The bill conditions a CERCLA liability shield for the Secretary of the Army on carrying out contaminated‑sediment removal or remediation pursuant to a joint plan that the Army develops with the non‑Federal interest and that the EPA Administrator approves. The joint plan must incorporate relevant National Contingency Plan requirements, describe work and disposal methods, assign roles and funding sources, and may include additional EPA terms.
Who It Affects
Directly affects the U.S. Army Corps of Engineers, non‑Federal sponsors (local governments, port authorities, etc.) that partner on water resources projects, and the EPA through a new plan‑approval role. It also touches dredging contractors, environmental consultants, ports and maritime operators, and potentially responsible parties (PRPs) subject to later cost‑recovery actions.
Why It Matters
By tying Corps operations to EPA‑approved plans and narrowing CERCLA exposure for the Secretary, the bill aims to accelerate federally supported sediment cleanup while keeping EPA’s technical oversight. That dual approach shifts legal risk from the Corps, concentrates procedural control in the approval process, and may alter who pays upfront versus who ultimately bears response costs.

What This Bill Actually Does
The CLEAN–UP Act sets up a joint planning mechanism that brings the Army Corps, the non‑Federal project sponsor, and the EPA into a single, EPA‑approved remediation plan before contaminated‑sediment work moves forward. The plan must meet National Contingency Plan‑related requirements the EPA deems relevant, explain exactly what work will be done, say how dredged material will be disposed of, spell out who does what, and identify likely funding sources.
The Administrator may add other terms necessary to protect health and the environment.
If the Corps carries out removal or remediation under such a joint plan, the bill bars CERCLA liability for the Secretary for releases that occur as a result of the covered activity. That protection is limited to the Secretary and applies only when the work strictly follows the approved plan.
At the same time, the statute explicitly preserves the federal government’s power to pursue cost recovery from PRPs for response costs the Corps incurs.Before starting a covered activity, the Corps must document the hazardous substances present in the sediment it plans to address and make an effort to identify potentially responsible parties. The Corps also must consult with interested federal, state, and local officials and provide an opportunity for public comment while developing the joint plan.
Those steps build a record that supports both the environmental rationale for the work and the legal posture around liability and cost allocation.Practically, the bill applies to two narrow categories of activities: water‑resources projects Congress has specifically authorized for contaminated‑sediment work, and projects carried out under WRDA section 312(f). That means routine navigation dredging unrelated to a specific remediation authorization is outside this statutory scheme.
The combination of EPA plan approval, required plan elements, and the pre‑action documentation obligations will change how sponsors and the Corps sequence site investigation, contractor procurement, disposal siting, and funding commitments.
The Five Things You Need to Know
Section 2(a) bars CERCLA liability for the Secretary of the Army for releases resulting from a covered activity carried out in accordance with an EPA‑approved joint plan.
Section 2(b) requires joint plans to include relevant National Contingency Plan requirements, a work description, dredged‑material disposal method, roles and funding identification, and any other EPA‑required terms.
Section 2(c) mandates consultation with federal, state, and local officials and an opportunity for public comment during joint‑plan development.
Section 2(d) requires the Corps to document hazardous substances in the target sediment and to seek to identify potentially responsible parties before carrying out the covered activity.
Section 2(e) preserves the United States’ right to seek cost recovery under CERCLA for response costs the Corps incurs while carrying out a covered activity.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
Provides the Act’s formal name: the Coordinated Leadership for Environmental and Aquatic Needs–Unified Planning Act, or the CLEAN–UP Act. This is purely nominal but signals congressional intent to prioritize coordination between federal, state, and local actors on sediment remediation projects.
CERCLA liability limitation for the Secretary
Establishes that the Secretary of the Army is not liable under CERCLA for hazardous‑substance releases or pollutant discharges that result from a covered activity when the activity is performed in accordance with a joint plan approved by the EPA Administrator. Mechanically, this is a targeted immunity: it does not amend CERCLA broadly, it attaches the shield to compliance with the approved plan, and it applies only to the Secretary (not to non‑Federal sponsors or contractors unless otherwise protected by other authorities). The practical effect is to lower legal risk for Corps decision‑making tied to approved plans.
Joint plan content and EPA terms
Specifies required plan elements: protection of human health and the environment; incorporation of relevant and appropriate National Contingency Plan requirements; a clear statement of the work to be performed; explicit identification of dredged‑material disposal methods; delineation of roles and responsibilities between the Corps and the non‑Federal interest; and identification of funding sources. The Administrator may add additional terms and conditions — a lever that lets EPA shape project design and monitoring requirements as part of granting the liability protection.
Consultation and public comment
Requires the Corps to consult with interested federal, state, and local officials and to provide an opportunity for public comment when developing the joint plan. This creates administrative record points that agencies can rely on for both environmental justification and legal defense, but also imports procedural timelines and potential for contested public input to slow projects.
Pre‑action documentation and PRP identification
Obligates the Corps to document hazardous substances present in the sediment slated for remediation and to ‘seek to identify’ any potentially responsible parties before carrying out the work. Those steps are designed to create transparency about contamination levels and to preserve the federal government’s ability to later seek reimbursement, but the language ‘seek to identify’ is permissive and could be a source of dispute over sufficiency of pre‑work due diligence.
Cost recovery preserved
Clarifies that nothing in the liability limitation prevents the federal government from pursuing CERCLA cost recovery from responsible parties for response costs the Corps incurs. That maintains the statutory toolset enabling the government to recoup expenditures and keeps intact the polluter‑pays enforcement mechanism even when the Corps receives liability protection.
Definitions and scope
Provides key definitions: ‘covered activity’ is limited to contaminated‑sediment removal or remediation under a project specifically authorized by Congress for that purpose or under WRDA section 312(f); ‘Secretary’ is the Secretary of the Army acting through the Chief of Engineers; and it imports CERCLA definitions for ‘hazardous substance’ and ‘pollutant or contaminant.’ This scoping prevents the statute from applying to general Corps activities outside those defined authorities.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- U.S. Army Corps of Engineers — Reduces CERCLA exposure when working under EPA‑approved plans, which lowers litigation risk and can streamline operational decisions tied to Congressionally authorized remediation projects.
- Non‑Federal sponsors (ports, local governments, river commissions) — Gain clearer access to Corps technical capacity and federal execution while preserving a pathway to EPA oversight; may secure faster project delivery if plan approval is efficient.
- EPA — Gains formal approval authority to set conditions and require NCP‑related elements, concentrating technical control over remediation standards and monitoring in a single point of review.
- Ports and maritime operators — Stand to benefit from clearer disposal‑method determinations and a structured remediation pathway that can reduce uncertainty about navigation dredging impacts and future liability.
- Environmental and engineering firms — Will encounter clearer project scopes and plan‑driven specifications, which can make bidding and performance expectations more predictable.
Who Bears the Cost
- Non‑Federal sponsors — Must help develop the joint plan and identify funding sources; they may carry substantial upfront costs, cost‑share obligations, or long‑term maintenance responsibilities tied to the remediation project.
- EPA — Faces increased review and conditional‑approval workload; the agency may need to invest staff and technical resources to vet plans and to negotiate additional terms that come with the approval authority.
- Potentially Responsible Parties (PRPs) — Remain subject to federal cost‑recovery efforts for Corps response costs, and could face reimbursement claims even when the Corps had liability protection.
- Federal taxpayers — The Corps may proceed with remediation actions before cost recovery is achieved, creating potential short‑term fiscal exposure for the Treasury.
- Dredging contractors and disposal site operators — May incur higher compliance and monitoring costs to meet EPA‑required disposal methods and NCP‑related terms imposed through the joint plan.
Key Issues
The Core Tension
The central tension is between accelerating federally supported sediment cleanup by shielding the Corps when it follows an EPA‑approved plan, and preserving accountability and the polluter‑pays principle: giving the Corps operational cover can expedite action but risks shifting upfront costs and reducing direct CERCLA deterrence unless EPA oversight, PRP identification, and later cost‑recovery are robust and enforceable.
The bill creates a legal and administrative paradox: it narrows CERCLA exposure for the Secretary while preserving federal cost‑recovery from PRPs. That combination can speed federally led action but may also shift the timing of who pays — the government may front costs and then pursue PRPs, or PRPs may litigate the sufficiency of pre‑action identification efforts.
The statute’s use of ‘seek to identify’ PRPs is permissive and could become a battleground in cost‑recovery litigation about whether the Corps satisfied its investigative duty prior to remediation.
Operationally, the EPA’s power to add “other terms and conditions” gives it a strong conditional veto over the liability shield. EPA conditioning could introduce technical or monitoring requirements that increase project cost or duration.
Determining whether an activity was truly “carried out in accordance with” an approved plan is a discrete legal question that will invite litigation when releases occur; courts will be asked to parse deviations, emergent site conditions, and whether a release ‘resulted from’ the covered activity rather than pre‑existing contamination or unrelated discharges. Finally, the bill’s narrow scope — limited to Congressionally authorized projects and WRDA 312(f) actions — leaves ambiguity about remediation conducted under other federal authorities or emergency responses, creating potential gaps where neither the Corps nor other agencies have clear liability boundaries or coordination rules.
