Tracking sources of fugitive dust at Nipomo Mesa, California

High concentrations of fugitive dust have been experienced in the Nipomo Mesa area, southern San Luis Obispo County, California, to the extent that the California air quality standard for PM10 has been exceeded numerous times. Population centers on the Nipomo Mesa are landward (downwind) of the Oceano Dunes State Vehicular Recreation Area (SVRA)- an off-highway vehicle (OHV) use area on an extensive coastal dune field, as well as undisturbed coastal dunes, agricultural fields, and petroleum coke storage piles at a refinery. All of these sites are potential fugitive dust sources.
