MDAQMD headquarters in Victorville
Stretched out over almost 20,000 square miles of California’s vast desert expanse, the Mojave Desert Air Quality Management District is geographically the second largest of the state’s 35 air districts. As the air pollution control agency for San Bernardino County’s High Desert and Riverside County’s Palo Verde Valley, the District has primary responsibility for regulating stationary sources of air pollution located within its jurisdictional boundaries. To this end, the District implements air quality programs required by State and Federal mandates, enforces rules and regulations based on air pollution laws, and educates businesses and residents about their role in protecting air quality. The MDAQMD lies within the Mojave Desert Air Basin, which also encompasses desert portions of Kern, Los Angeles and Riverside Counties.
The District works to protect the health of over 550,000 residents by safeguarding the region's air quality. By partnering with the local communities and businesses, we implement regulations and programs to reduce air pollution and assist the High Desert in attaining ambient air quality standards.
The MDAQMD is committed to protecting air quality within its boundaries while supporting strong and sustainable economic growth. This is accomplished through a comprehensive and common-sense program of planning, regulation, compliance assistance, enforcement, monitoring, and public education.
The District consists of over 40 dedicated staff members, including engineers, inspectors, planners, community relations and other professionals, under the direction of the Executive Director. For a detailed list of our organization, please click on this link: District Organizational Chart
