66--Portable Emissions Monitoring System (PEMS)

The Environmental Protection Agency (EPA) plans to negotiate exclusively with Sensors, Inc. for the procurement of a Portable Emissions Measurement System (PEMS) under the authority of FAR 6.302-1. This system will be used by the EPA's Office of Research and Development, specifically the National Risk Management Research Laboratory's Air Pollution Prevention and Control Division, located in Research Triangle Park, North Carolina. The PEMS will support the Air, Climate, and Energy Research Action Plan by assessing emissions variations from on-road and non-road mobile sources in compliance with federal regulations and aligned with ongoing research by the Office of Transportation and Air Quality. By acquiring the same PEMS equipment currently used by OTAQ, the EPA aims to enhance the reliability and comparability of emissions data collected across these research divisions. Sensors, Inc. is identified as the sole source manufacturer of the required PEMS, which includes specific advanced analyzers such as a non-dispersive ultraviolet NOx analyzer, flame ionization detector, total hydrocarbon analyzer, and non-dispersive infrared analyzers for CO and CO2 measurement. The contract will also encompass basic technical training and engineering support during the system's commissioning and initial use. This procurement will be conducted as a single fixed-price purchase order following FAR Part 12 Commercial Procedures. Although the notice invites interested firms to express their capability to respond, it is not a solicitation for competitive quotations, and the EPA retains the sole discretion to proceed without competition. Responses must be submitted in writing within seven calendar days, with no consideration given to telephone inquiries.
