ORCAA works cooperatively with the Washington State Department of Ecology (Ecology) and the regional United States Environmental Protection Agency (EPA) to measure criteria ambient air pollutants, meteorological parameters, and other air-related data. ORCAA is a member of the Washington Air Monitoring Work Group, which includes representatives of Ecology and the Washington State Local Air Pollution Control Agencies.
This committee makes recommendations to Washington Air Quality Managers Group regarding air monitoring programs, including ambient air monitoring site locations. Ecology provides support for the air monitoring that ORCAA conducts. ORCAA currently operates and maintains air monitoring equipment for measurement of three of the six criteria pollutants: particulate matter (PM2.5), ozone (O3), and carbon monoxide (CO).
ORCAA and Ecology operate and maintain meteorological sensors (wind speed, wind direction, temperature, and relative humidity) and nephelometers (a device that continuously measures fine particulates and visibility).
