Air Quality Monitoring
The District operates four air monitoring stations within its tri-county jurisdiction: Jacobs Station (Humboldt County), Humboldt Hill Station (Humboldt County), Crescent City (Del Norte County), and Weaverville Station (Trinity County). Air monitoring data collected at these stations is reported to the EPA for determining compliance with the Federal Ambient Air Quality Standards.
Air monitoring stations are typically small buildings which contain sampling and monitoring equipment. They are usually accompanied by a meteorological station to measure wind speed, direction, temperature, and humidity. Meteorological information is collected to assist in determining the origin of pollution events and is used when preparing healthrisk assessments.

The California Air Resources Board (CARB) conducts routine audits of District equipment and procedures for quality assurance purposes. The most recent local air quality data is available from each of the District's monitoring stations. If you would like more information that what is provided on this website please contact District staff.
Each year, the District develops an Annual Network Plan for Ambient Air Montitoring to monitor pollutant levels in the District. The plan both summarizes the previous year's air quality data and discusses any expected changes in the monitoring process. Every year the plan is publicly noticed in July for public comment on the plan. Please contact District staff for further information.
