<p>Bot: Creating new article from JSON</p> <p><b>New page</b></p><div>⚠️ &#039;&#039;&#039;Potentially responsible party (PRP)&#039;&#039;&#039; is a designation under the United States [[Definition:Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) | Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)]] — commonly known as Superfund — identifying any individual, company, or entity that may be held liable for the costs of cleaning up a contaminated site. For insurers writing [[Definition:Environmental liability insurance | environmental liability]], [[Definition:General liability insurance | general liability]], or [[Definition:Commercial general liability (CGL) | commercial general liability (CGL)]] policies, a PRP designation is a significant trigger: it can activate long-tail [[Definition:Coverage | coverage]] obligations and set off complex disputes over [[Definition:Policy interpretation | policy interpretation]] spanning decades of [[Definition:Occurrence | occurrence]]-based coverage.<br /> <br /> 🔗 Once the [[Definition:Environmental Protection Agency (EPA) | Environmental Protection Agency (EPA)]] or a state environmental authority identifies a PRP, that party faces [[Definition:Joint and several liability | joint and several liability]] for [[Definition:Remediation | remediation]] costs, meaning any single PRP can theoretically be compelled to bear the full expense regardless of its proportional contribution to the contamination. PRPs frequently turn to their historical [[Definition:Insurance carrier | insurance carriers]], asserting [[Definition:Coverage | coverage]] under old CGL policies that may predate modern [[Definition:Pollution exclusion | pollution exclusions]]. Carriers must then investigate the [[Definition:Policy period | policy period]], applicable [[Definition:Endorsement | endorsements]], and the evolution of pollution liability language to determine whether and to what extent a [[Definition:Duty to defend | duty to defend]] or [[Definition:Indemnity | indemnity]] obligation exists. This process can involve dozens of insurers across overlapping policy years.<br /> <br /> 💼 The financial stakes attached to PRP claims have profoundly shaped insurance product design and [[Definition:Underwriting | underwriting]] practice. The wave of Superfund-related litigation in the 1980s and 1990s prompted the industry to adopt the [[Definition:Absolute pollution exclusion | absolute pollution exclusion]] in standard CGL forms and spurred the development of dedicated [[Definition:Environmental liability insurance | environmental insurance]] products with carefully scoped coverage grants. Today, when [[Definition:Risk management | risk managers]] and [[Definition:Insurance broker | brokers]] evaluate an organization&#039;s environmental exposure, the possibility of PRP designation is a central concern that drives both the structure of coverage purchased and the [[Definition:Due diligence | due diligence]] performed during mergers and acquisitions.<br /> <br /> &#039;&#039;&#039;Related concepts:&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:Environmental liability insurance]]<br /> * [[Definition:Pollution exclusion]]<br /> * [[Definition:Commercial general liability (CGL)]]<br /> * [[Definition:Long-tail liability]]<br /> * [[Definition:Remediation cost cap insurance]]<br /> * [[Definition:Joint and several liability]]<br /> {{Div col end}}</div>
