RFQ #2025059 - Portable Emissions Measurement System (PEMS) and Accessory

The contract pertains to the acquisition of a Portable Emissions Measurement System (PEMS) and its accessories, which are essential for measuring exhaust emissions from off-road and non-road equipment including construction and agricultural machinery, locomotives, cranes, and small off-road engines (SORE). These measurements are conducted during normal operation using primarily Gas, Particulate Matter, and system controller units. The purpose of this system is to support the California Air Resources Board's (CARB) compliance, surveillance, inventory, and research programs in alignment with California Code of Regulations Title 13 and Code of Federal Regulations Title 40 requirements. Securing this PEMS is critical for the Office of Research Planning and Emission Measurement Services (ORPEMS) to carry out timely and accurate exhaust emissions testing in accordance with both federal and state regulations. Without it, the staff’s ability to perform essential off-road emissions testing and subsequently provide the data needed to enforce these mission-critical regulations would be severely compromised. The solicitation was posted on December 5, 2025, with a response deadline of December 19, 2025, and is managed by the California State Air Resources Board, with Jian Huang as the primary point of contact. The system will be utilized within California to ensure ongoing regulatory compliance and support environmental research initiatives.
