Bona Fide Prospective PurchaserEdit
Bona fide prospective purchaser (BFPP) is a key mechanism in environmental law designed to unlock the redevelopment of contaminated or potentially contaminated properties by private buyers while preserving accountability for cleanup. Rooted in the broader framework of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), BFPP status can shield a buyer from certain cleanup liabilities that would otherwise attach under the statute, provided the buyer meets a defined set of criteria. In practice, the BFPP defense is meant to align private investment and responsible remediation, encouraging market-driven cleanup of brownfields while ensuring that purchasers act with due diligence and remain engaged in addressing any remaining hazards.
Supporters stress that BFPP protection reduces regulatory and financial uncertainty, enabling redevelopment that would be deterred by the specter of unlimited cleanup liability. This, in turn, can revive blighted districts, create jobs, and incentivize lenders to finance deals they would otherwise classify as too risky. The mechanism is framed as a property-rights friendly, market-based tool that channels private capital toward productive use of land while maintaining guardrails to prevent shirking of cleanup responsibilities. The concept sits at the intersection of private property rights, risk management, and public health, with safeguards designed to ensure that those who benefit economically from a site also contribute to its remediation.
Legal framework
The BFPP defense rests within CERCLA’s liability scheme. The central idea is that a party who purchases a facility and undertakes proper due diligence and ongoing care can avoid liability as a potential responsible party for cleanup, to the extent that the buyer did not cause or contribute to the contamination. The defense is most commonly invoked by buyers of properties known or suspected to be contaminated, who intend to continue business operations or repurpose the site in a manner that remains protective of public health and the environment. Related concepts in CERCLA – such as the innocent landowner defense – sit alongside BFPP in the broader landscape of liability protections intended to prevent prohibitively high liabilities from blocking legitimate redevelopment projects. For more context, see CERCLA and Superfund.
The practical framework is built around standards for due diligence and ongoing stewardship. The All Appropriate Inquiries (AAI) process governs the initial assessment of the site, and the standards governing AAI are articulated in sources such as All Appropriate Inquiries and the widely used ASTM E1527 standard. In addition, BFPP status requires ongoing compliance with land-use controls and cooperation with regulators, as well as attention to any residual contamination that could pose risk to human health or the environment. See also references to brownfields redevelopment as the typical setting for BFPP determinations.
Criteria for BFPP status
A purchaser seeking the bona fide prospective purchaser defense generally must satisfy a structured set of criteria designed to ensure that the buyer acted with due diligence and is committed to orderly remediation. Core elements include:
All Appropriate Inquiries (AAI) into the property’s previous uses and ownership, conducted in accordance with applicable guidelines (often via the ASTM E1527 process). This is the due diligence that establishes a defensible starting point for evaluating risk. See All Appropriate Inquiries and ASTM E1527.
No knowledge, and no reason to know, that hazardous substances were disposed of on the property at levels or in ways that would trigger CERCLA liability, aside from information uncovered through the AAI. This helps determine that the buyer did not willfully ignore known problems.
No affiliation with any party responsible for the releases (or with someone who caused or contributed to the contamination) that would undermine the integrity of the defense. This keeps the defense aligned with the purchaser’s independent stewardship.
The purchaser undertakes, or commits to undertake, all appropriate response actions to remove, mitigate, or manage contamination to the extent necessary to comply with applicable cleanup requirements, and to prevent future releases. This obligation emphasizes action and accountability rather than mere ownership.
The purchaser exercises due care with respect to the contamination, to the extent required by the site conditions and the nature of the release. This includes implementing protective measures and ensuring that operations do not exacerbate risk.
The purchaser provides all information that is reasonably available to the government about the facility and its condition. This transparency supports regulator oversight and informed decision-making.
The purchaser complies with any institutional controls or land-use restrictions established for the site as part of the remedy to ensure ongoing protectiveness. These controls can limit uses or impose monitoring requirements intended to prevent exposure to contamination.
In practice, the defense is narrowly scoped. It does not grant a blanket shield from all environmental exposure, and it is not a substitute for responsible remediation. When a buyer fails to meet any element, the defense may not apply.

Benefits and limitations
Benefits - Encourages brownfield redevelopment by reducing the fear of open-ended cleanup liability for buyers who perform due diligence and commit to remediation. This can unlock underutilized or long-vacant properties and catalyze investment in communities. - Aligns private incentives with public health and environmental goals by tying liability protection to proactive steps, including information disclosure and ongoing stewardship. - Provides a predictable framework that can reassure lenders and investors, helping to mobilize capital for site redevelopment. See also brownfields and environmental finance.
Limitations and caveats - BFPP is not a free pass. It only shields certain liabilities under CERCLA; other legal avenues of liability, including state remedies and third-party claims, may still apply. See discussions of potentially responsible party and lender liability for related considerations. - The defense hinges on adherence to specific procedures and ongoing obligations. If a buyer’s due diligence or stewardship is found deficient, the protections may not apply. - State-level implementations and interpretations vary, which can affect the certainty and availability of BFPP protection. This creates a mosaic of regulatory outcomes rather than a single nationwide standard. - Critics argue that the structure can be used to shield deliberate noncompliance or to delay comprehensive cleanup, although proponents contend that robust requirements and oversight minimize such risk.
Controversies and debates
Controversies around BFPP tend to center on balancing private market incentives with public accountability.
Supporters’ case: Proponents argue BFPP strikes an essential balance between property rights and environmental protection. By putting in place solid due diligence (AAI), ongoing care, and clear cooperation with regulators, BFPP channels private capital into productive reuse of contaminated land. The policy framework is seen as a pragmatic approach to eliminating urban blight, reducing blight-driven costs for communities, and fostering job creation, all while retaining meaningful cleanup obligations.
Critics’ case: Critics contend that any liability shield can create moral hazard if buyers assume the defense without giving due weight to long-tail contamination risks, or if the defense is applied too broadly in ways that shield noncompliant behavior. They also worry about uneven implementation across states and the possibility that the defense may be used to structure transactions in which the true cost of cleanup remains externalized or deferred. From this vantage, the debate centers on whether the guardrails are sufficiently robust to prevent the transfer of cleanup costs to taxpayers or to future site users.
Woke or reform-oriented criticisms (common in public discourse but controversial among some scholars): Some critics frame BFPP as a tool that tilts the balance toward developers at the expense of communities seeking rapid, comprehensive cleanup. In a conservative counter-narrative, supporters argue that the framework, with its stringent conditions and ongoing obligations, actually strengthens accountability and reduces the likelihood of “walk-away” scenarios, while avoiding immobilizing regulation that would deter investment in urban cores. The pushback to such criticisms typically emphasizes the administrative and financial realities of redeveloping brownfields, the role of private capital in risk-bearing projects, and the necessity of clear standards to avoid indefinite liability.
Implementation and governance questions: Debates frequently address how strictly AAI must be applied, how to assess “due care” in diverse site contexts, and how to harmonize federal protections with state environmental programs. The interaction of BFPP with the innocent landowner defense, institutional controls, and state brownfield programs is also a subject of ongoing policy and scholarship.
