Justification and Approval Redacted.pdf

This document is a Justification and Approval for a sole source contract modification. The Department of the Army Corps of Engineers Louisville District intends to sole source a modification (P0007) to Task Order W912QR21F0421 for a PFAS Remedial Investigation at the Iowa Army Ammunition Plant. The modification is justified under FAR 6.302-1(a)(2)(iii)(B) for the continued provision of highly specialized services where award to any other source would result in unacceptable delays. The contract requires the use of EPA Draft Method 1633 for the definitive analysis of PFAS in environmental matrices other than drinking water, performed by a DoD ELAP-accredited laboratory. No other methods may be used for regulatory compliance, risk assessment, or comparison to project screening/action levels without approval. This policy supersedes and cancels a prior ASD(S) memorandum on PFAS methodology.
