Hunters Point Power Plant Closure and Cleanup

Dust Control (including naturally occurring asbestos)

Breathing airborne dust can be harmful to health both because of the dust itself and because of other materials that can become airborne with the dust. Here, those other materials could include naturally occurring asbestos (NOA) and metals (both naturally occurring and from power plant operations). NOA is present because portions of the former power plant were built on fill material. The fill was derived from local serpentine rock (which is the natural source of NOA), which is present throughout the Bayview Hunters Point community and many other areas of California. For all of these reasons dust control has been a high priority while soil disturbing work is underway.

Depending on the work being performed, workers wear personal protective equipment such as gloves, goggles, overalls and respirators. These, and other worker safety practices at the site, satisfy all applicable requirements of the Occupational Safety and Health Administration (OSHA) and other regulatory agencies.

Due to the presence of NOA in the area, the remedy for the site includes installing a protective cover upon completion of soil cleanup activities, as pictured below. A protective cover is now in place throughout the site, which the exception of Area H, which is a portion of the property that was never use for PG&E Power Plant operations. Area H, also pictured below, has been reseeded with locally collected native seeds.
