Guidance: 2015 CERCLA RD/RA UAO and SOW

Transmittal memorandum announcing the issuance of the revised model Remedial Design/Remedial Action (RD/RA) Unilateral Administrative Order (UAO) and the new model RD/RA UAO Statement of Work (SOW). Issued 9/30/2015.

The model RD/RA UAO is for use by EPA staff when issuing RD/RA UAOs to potentially responsible parties (PRPs) under section 106 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA, commonly referred to as Superfund). It is designed to be used in conjunction with the model RD/RA UAO SOW, which is the technical attachment to the UAO that sets forth the procedures and requirements for implementing the RD and RA under the UAO. The revised model RD/RA UAO supersedes the 1990 model document.

The transmittal memorandum also announces updates to the RD/RA Consent Decree (CD) SOW, originally issued on 9/29/14, to conform to the new RD/RA UAO SOW, and includes as an appendix an explanation of the changes to the RD/RA CD SOW.

The two model documents included with the transmittal memorandum are available in Word format from the Cleanup Enforcement Model Language and Sample Documents Database:

The transmittal memorandum and appendix are available in PDF below.
