Procurement of 157, 500 “Custom” made 4” in diameter, air filter disc made of po

The U.S. Environmental Protection Agency (EPA), specifically the Office of the Chief Procurement Officer's Land, Enforcement, and Air Division, has issued a Special Notice for the procurement of 157,500 custom-made 4-inch diameter air filter discs composed of polyester felt material. This sole source purchase order, valued at approximately $197,300, is being awarded to H.C. Warner Inc., a small business entity, for supply to the EPA's National Analytical Radiation Environmental Laboratory (NAREL). The procurement is being conducted under the authority of FAR Parts 12 and 13 via FedConnect. The agency is seeking a waiver to bypass competitive bidding requirements based on the unique specifications and capabilities required for this specialized equipment. This Special Notice was posted on February 19, 2026, with a due date of February 23, 2026.

The primary objective of this procurement is to supply specialized Gusmer Cellulo polyester air filter discs that enable uninterrupted high-volume air sampling for extended periods of over one week without operator intervention—a capability the EPA has determined no alternative filter can provide. The filters support NAREL's Radiation Network Monitoring System (RADNET), which operates over 100 air monitoring stations throughout the United States to collect and analyze particulate matter for radioactive contamination assessment. The agency emphasizes that any change in filter composition could compromise the validity and comparability of long-term laboratory data trends, making these specific filters essential for program continuity. The contract will operate under a 4-month base period with a firm fixed-price structure. While this is classified as a no set-aside procurement, H.C. Warner Inc. is identified as a small business, and the sole source justification under FAR 13.106-1(b)(1)(i) reflects the specialized nature of the required filtration technology.
