While plutonium is no longer produced at Hanford, we continue to measure air quality to ensure that it is safe for those who live and work in the area. We follow federal and state air quality standards for outdoor air to prevent air pollution from reaching levels that are harmful to human health.
When emissions don't meet standards, we take corrective actions to bring them into compliance.
Ecology, the Washington Dept. of Health, EPA, tribes, and local clean air agencies maintain a network of air monitoring stations around the state to measure air pollution. Air quality is measured at facilities that have air handling systems, in the tank farms, and at cleanup sites.
