Particulate Matter Information

The OHMVR Division proposes to install, operate, and maintain meteorological, sand flux (i.e., sand movement), and particulate matter monitoring equipment and dust and track-out control measures primarily in and within the vicinity of Pismo State Beach and Oceano Dunes SVRA in San Luis Obispo (SLO) County. The OHMVR Division may install monitoring equipment in and within the vicinity of Rancho Guadalupe Dunes County Park in Santa Barbara County. The proposed equipment and control measures are intended to provide information on the dynamics of dust generation at Pismo State Beach and Oceano Dunes SVRA, to help limit high levels of suspended particulate matter (PM) with an aerodynamic diameter of 10 micrometers or less (PM10) on the Nipomo Mesa, in SLO County, and also to comply with SLO County Air Pollution Control District Rule 1001, Coastal Dunes Dust Control Requirements, which requires the OHMVR Division, as operator of Oceano Dunes SVRA, to develop a Particulate Matter Reduction Plan to minimize emissions of PM10 from the area under its control. In accordance with CEQA an Environmental Impact Report (EIR) is being prepared.
