The intent of this document is to outline the components, which will comprise a naturally occurring asbestos abatement program for site work. Background Naturally occurring asbestos has been mapped in approximately 11 square miles of Fairfax County, which includes a part of Fairfax City. Asbestos bearing rock are interspersed in the Green Stone Rock Formations that underlie the surface soils in the Orange Soils Group. Surface exposure of these rock formations is not usually seen, but it does happen. Even though the soils do not typically contain asbestos, they provide a good surface marker for detecting the possible presence of asbestos bearing rock.
Asbestos is a generic term used to describe the fibrous form of six different minerals.
The minerals identified in this particular soil group are actinolite and tremolite. Before beginning any activities that have changed and not in an agreed upon plan, an amended plan must be submitted and reviewed by Fairfax County Health Department Air Monitoring and Trends Analysis. The purpose of an asbestos abatement plan is to maintain safe working conditions on the construction site and to prevent migration of asbestos laden dust off the site. Excavated soils suspected to contain asbestos that are held on site must be kept wet or covered until properly disposed. Adequate vehicle and equipment cleaning must be performed to avoid the spread of asbestos to places such as parking lots and roads.
