Presolicitation Notice SSD_Redacted 143061-26-0083.pdf

This is a Single Source Determination justification document using Simplified Acquisition Procedures (SAP) for a federal contract action under the simplified acquisition threshold, issued by the Department of Commerce, NOAA Acquisition and Grants Office (AGO), Western Acquisition Division, Alaska Fisheries Science Center (AFSC), and REFM Division.

The contract requires histological analysis services for fish ovaries to support fisheries stock assessments under the Magnuson-Stevens Fishery Conservation and Management Act. The services involve processing fish ovary samples to inform research on reproduction and maturity of commercially important species, including walleye pollock. NOAA has identified Histology Consultation Services, Inc. (located at 207 N. Harness St., PO Box 770, Everton, WA 98247) as the sole source capable of meeting requirements. The justification cites two supporting rationales: compatibility with existing systems and equipment, as Histology Consultation Services has provided these services for over five years with specialized expertise and equipment ensuring sample consistency; and the specialized nature of histological processing, as the company possesses unique expertise in processing marine fish ovaries using the Schiffs/Mallory staining technique, which provides superior contrast for identifying ovary structures and spawning events. Market research identified only two potential laboratories performing this work, with Histology Consultation Services being the only vendor capable of delivering the required Schiffs/Mallory staining methodology. The document includes certification statements from the technical representative and determining official affirming the single source determination is accurate and complete.
