This 3 minute video showing the particulate matter plume originating in the riding area of the Oceano Dunes State Vehicular Area where off roading breaks the dune crust. This plume is health threatening. The San Luis Obispo County Air Pollution District has measured the particulate matter for over two decades and found the concentrations of silica (sand) to be above state and federal health standards. The San Luis Obispo County Board of Supervisors has taken no action to protect residents downwind, and on April 15, 2008 granted an extension of an operating agreement which was scheduled to expire next month.
