BLM-MT Air Monitoring, North Central District

data obtained from these stations fills a large spatial gap in air quality information and the data are used to support BLM air analyses and planning implementation. Objectives: The purpose of this project is to provide air quality data used to determine compliance with air quality standards and protect public health by continuously operating two air monitoring stations in central (Lewistown) and northern (Malta) Montana. Public Benefit: Continuous measurement and reporting of air quality information is used to protect public health, evaluate effectiveness of air resource management strategies, and ensure compliance with ambient air standards.
