YSAQMD is sad to announce the passing of Executive Director and Air Pollution Control Officer, Mat Ehrhardt, P.E.

It is with profound sadness that the Yolo-Solano Air Quality Management District (YSAQMD) announces the passing of Executive Director and Air Pollution Control Officer Mat Ehrhardt, P.E. on June 26, 2022.

Mat held a degree in Mechanical Engineering from California State University of Sacramento, where he was on the Dean’s list (1990-1992) and a member of the Tau Beta Pi Engineering Honor Society.   He came to the District in 1997 as an Associate Air Quality Engineer, earning his Professional Engineering license in Mechanical Engineering in 1997 before promoting to Supervising Air Quality Engineer in 2000 and then Deputy Air Pollution Control Officer in 2002. In 2005, he became the Executive Director of YSAQMD, leading operations for nearly 20 years.

Mat was a strong advocate for clean air, but in a way that made sense for all stakeholders, including the regulated community. Though Yolo-Solano is a medium size district, Mat’s impact on statewide air quality policy issues was undeniable, including serving as President of the California Air Pollution Control Officer’s Association from 2009 to 2010.

District staff extend their deepest condolences to his wife, daughter and family and asks to keep them in your thoughts at this difficult time.
