The U.S. Environmental Protection Agency (EPA) Office of Air and Radiation has awarded a $41.3 million Indefinite Delivery Contract (IDC) to WSP USA Environment & Infrastructure Inc., a for-profit engineering and professional services firm, to operate the Clean Air Status and Trends Network (CASTNET) program through July 2025. CASTNET is a major EPA initiative that monitors air quality and atmospheric deposition across over 100 rural sites in the U.S. and Canada.

The contract includes a series of delivery orders for various CASTNET-related tasks, such as routine operations, non-routine maintenance and repairs, supplemental monitoring studies, and support for tribal air quality monitoring. These delivery orders range in value from around $30,000 to over $3.8 million and utilize time-and-materials pricing. The work will primarily be performed at WSP's facility in Penllyn, Pennsylvania. There are no set-aside designations associated with this IDC or its task orders. The contract aims to continue the long-running CASTNET program, which provides critical data to EPA for analyzing air pollution trends and informing regulatory decisions under the Clean Air Act.
