BARRY R. WALLERSTEIN, D. Env.
Executive Officer

A longtime Southern California resident, Barry R. Wallerstein holds a doctorate in environmental science and engineering from the University of California at Los Angeles - School of Public Health, and M.S. and B.S. degrees in biological science from the University of Southern California. He has two decades of experience in urban planning and environmental studies, with an emphasis in air pollution control and public policy development. He has been AQMD's Executive Officer for ten years, having served the agency in increasingly responsible positions since 1984.

Previously in his career, Barry held positions as an Environmental Control Administrator at Northrop and as a member of rule development staff at the California Air Resources Board.

As executive officer, he serves as chief of staff to implement environmental protection policies as approved by the agency's 12-member Governing Board, working proactively with state and federal regulatory officials, local governments, regulated businesses, and community stakeholders. In recent years, he has executed innovative programs to:

  • achieve concurrent reduction of greenhouse gases, criteria pollutants, and air toxics for simultaneous progress toward public health & climate protection goals;
  • strengthen public-private investment in clean fuels and renewable energy technologies;
  • address specific community and neighborhood environmental justice issues, including the evolving area of cumulative impacts;
  • identify and reduce air toxics exposure (especially diesel particulate); and
  • integrate voluntary cleanup incentives into regulatory structures.

During Barry's tenure, he has overseen the development and continuing implementation of the first local-district air toxics control plan in the United States, an outgrowth of the agency's Multiple Air Toxics Exposure Studies (MATES-II and III). Findings from these studies point to diesel engine exhaust as the primary contributor to community cancer risk from air toxics in Southern California - - especially in neighborhoods adjoining heavy diesel activity such as ports, freeways, and rail yards. As a result, Barry has also led implementation of AQMD's historic Clean Fleet Vehicle rules, which are achieving international recognition as a strategic model to accelerate the transition to clean-fueled fleets based on advanced technologies.
