High-Resolution Mobile Monitoring

The Washington State Department of Ecology (ECOLOGY) is seeking a contractor to conduct a High-Resolution Mobile Monitoring (HRMM) study across multiple Washington counties, including Franklin, Grant, Grays Harbor, Chelan, and Yakima. The primary objective is to obtain a comprehensive dataset of multiple criteria, hazardous, and toxic air pollutants through mobile monitoring in overburdened communities and participating Tribal communities. The successful contractor will be responsible for developing a comprehensive monitoring plan, conducting mobile air quality measurements, processing and analyzing data, and creating interactive visualizations. Key deliverables include a detailed monitoring strategy, high-resolution air quality data collection, and comprehensive data analysis that supports environmental justice efforts. The Request for Proposal (RFP 2605 AQP) was issued on October 20, 2025, with proposals due by December 15, 2025, at 4:00 pm local time. The initial contract period will run from the date of signature until June 30, 2027, with potential extensions up to 24 months.

The contract has specific budget limitations, with a total budget of $8,000,000 and a strict constraint that no more than $500,000 can be used for procuring or building mobile monitoring platforms and equipment. The study will specifically target census tracts with high Environmental Health Disparities scores, focusing on overburdened communities across various Washington State regions. Funding for the project will come from ECOLOGY's Air Quality Program and is contingent on legislative reappropriation. While the RFP does not explicitly detail set-aside designations or restrictions on responding organizations, the complex technical requirements suggest that potential bidders should have significant expertise in air quality monitoring, data analysis, and environmental justice research. The project aims to inform future air monitoring strategies and identify communities most impacted by air pollution, with the ultimate goal of supporting broader environmental justice initiatives in Washington State.
