The California Legislature created the Air District in 1955 as the first regional air pollution control agency in the country, recognizing that air emissions overflow political boundaries. The nine counties of the San Francisco Bay Area form a regional air basin, sharing common geographical features and weather patterns, and therefore similar air pollution burdens, which cannot be addressed by counties acting on their own. The Bay Area Air Quality Management District is the public agency entrusted with regulating stationary sources of air pollution in the nine counties that surround San Francisco Bay: Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, southwestern Solano, and southern Sonoma counties. Vision A healthy breathing environment for every Bay Area resident. Mission To protect and improve public health, air quality, and the global climate. Core Values Excellence - Air District programs and policies are founded on science, developed with technical expertise, and executed with quality.

Collaboration - Involving, listening, and engaging all stakeholders, including partner agencies, to create broad acceptance for healthy air solutions.

Environmental services are highly fragmented, with many niche providers focusing on only one region or service offering. Spheros will serve as a unified platform to support public and private sector clients across the life cycle of their needs, including regulatory consulting, advisory, response, measurement, and analysis. The environmental services industry is driven by many long-term secular drivers including increased environmental awareness, enhanced regulations, and greater consumer demand. As increased consumer demand fuels more industrial activity, the resulting environmental challenges continue to grow in number, scope, and complexity. Further, damage and disruptions caused by climate change and other disasters to vulnerable infrastructure create a greater need for expert services and industrial operations often require continuous monitoring and testing to comply with applicable laws and regulations.
