Oceano Dunes Dust Mitigation

Coastal Dunes Dust Rule

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 Dunes Dust Studies

2013 Dunes Monitoring Study

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.

Study Results: Wind and PM10 Characteristics at the ODSVRA from the 2013 Assessment Monitoring Network

Study Results: 2013 Intensive Wind Erodibility Measurements At and Near the ODSVRA: Preliminary Report of Findings

2011 Dust Mitigation Study

In 2011, APCD and State Parks jointly funded a study by Desert Research Institute (DRI) to design and test various dust reduction control strategies at the Oceano Dunes State Vehicular Recreation Area (ODVSRA). STUDY RESULTS »

2007 Dunes Vegetation Study

Revegetation is an important dust reduction strategy at the ODSVRA. In 2007, State Parks published a comprehensive study of vegetation coverage within the ODSVRA, including the influence of offroad vehicle activity, detailed descriptions of revegetation efforts, and recommentations for ensuring future revegetation efforts are successful.

South County PM Workshop

A public workshop was held on September 7, 2011 at the Ramona Garden Park Center in Grover Beach. Information from the meeting and presentations are listed below.

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.
