At the November 16, 2011 meeting, the APCD Board approved the Coastal Dunes Dust Control Rule 1001 to require implementation of dust control measures on coastal dunes where vehicle activity occurs. The rule, staff report, presentation and implementation milestones can be downloaded from the links below.
State Parks conducted a comprehensive monitoring study in the spring and summer of 2013 to help determine the most appropriate locations to site the comparison air monitoring stations and the dust control mitigation measures required by APCD's Rule 1001. The results of those studies are discussed in the two documents listed below. The raw data for each of these documents can be obtained by contacting the OHV Division of the California Department of Parks and Recreation.
A public workshop was held on September 7 at the Ramona Garden Park Center in Grover Beach. Information from the meeting and presentations are listed below.
APCD, State Parks and the County have been working cooperatively to evaluate and develop potential solutions to the particulate matter (PM) emissions from the Oceano Dunes State Vehicular Recreation Area (SVRA) that are impacting downwind neighborhoods. Significant progress has been made to date, including the hiring of technical experts from the Desert Research Institute (DRI) in Reno to assist with this effort. The pilot project scope of work below is currently being implemented at the Oceano Dunes during the spring windy season to test ways to reduce PM emissions. Next up is the development of a long-term PM Reduction Plan for the Dunes. The Plan is expected to be completed sometime this fall, and will be designed to meet the requirements of the Air District's fugitive dust regulation currently under development.
The Phase 2 Study was conducted to determine the cause of high levels of airborne particulate matter impacting air quality and public health on the Nipomo Mesa, and whether offroad vehicle activity on the Oceano Dunes is a contributing factor. The APCD and its study partners hosted a public workshop on March 3 to share the results of the Study, followed by presentation of the results to the APCD Board and their acceptance of the report and findings on March 24, 2010. Documents relevant to this portion of the study are listed below.
A year long particulate monitoring study was initiated by the District from April 2004 through March 2005 to better delineate the nature and extent of the particulate problem observed on the Mesa. Comprehensive sampling of both fine (PM2.5) and coarse (PM10) particulate matter was conducted across the Mesa. The results of this study are available in the Nipomo Mesa Particulate Study 2007.
