Coastal Dunes Dust Control Rule
At the November 16 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, and presentation can be downloaded from the links below. The staff report contains the background and justification for adoption of the rule, as well as detailed responses to all significant and/or technical written comments submitted on the rule.
South County PM Workshop
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.
South County Particulate Matter Update
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.
South County Phase 2 Particulate Matter Study
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.
Raw Data
South County Phase 1 Particulate Matter Study
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.
