Quick Summary
The Environmental Protection Agency (EPA), specifically the Office of Air and Radiation Procurement Branch (OPB), has issued a Special Notice for the sole source procurement of 157,500 custom 4-inch polyester air filter discs. This requirement is for the Office of Air and Radiation (OAR), National Analytical Radiation Environmental Laboratory (NAREL), Radiation Network Monitoring System (RADNET). The estimated value for this effort is $197,300.00. Responses regarding this sole source action are due by February 23, 2026.
Scope of Work
The EPA requires 157,500 custom-made 4-inch diameter air filter discs, made of polyester felt type material. These filters are critical for the NAREL RADNET air filter program, which operates high-volume air monitoring stations across over 100 locations in the United States. The custom filters, currently provided by H.C. Warner Inc., are essential because they enable uninterrupted high-volume air sampling for over one continuous week without operator intervention. The EPA states that no other known filter provides this required capability, and any change in filter composition could invalidate the evaluation of long-term data trends from laboratory analyses.
