Report: PRP Search Manual (2009 edition with 2011 addendum)

The 2009 "PRP Search Manual" provides guidance on how to search for potentially responsible parties (PRPs) that may be liable for cleanup at a Superfund site. Issued 9/30/2009. The manual was amended in 2011 to add an addendum and again in 2012 to update appendix 6 of the manual. The manual gives the user historical background on Superfund and its enforcement program and describes the planning stages, baseline tasks and followup tasks for conducting effective PRP searches. Procedures and information contained in the manual are based on current EPA policy and guidance.

The manual, divided into four chapters, 13 appendices, and one addendum, is available for downloading as a complete document or by individual chapter, addendum, or appendix. The November 2011 addendum informs users of three guidance documents, issued after publication of the manual, that focus on: (a) documentation of completed PRP search activities in certain situations related to cost recovery; and (b) the definition and tracking of "Preliminary PRP Search Completion" in EPA's Comprehensive Environmental Response, Compensation, Disable rich-text and Liability Information System (CERCLIS).
