Learning about dust control and naturally occurring asbestos

Breathing airborne dust can be harmful to your health. The damage can come from the dust and other materials that can become airborne along with it.

At the Hunters Point Power Plant, the other materials may include naturally occurring asbestos (NOA) and metals. NOA and metals are present because portions of the former power plant were built on fill material. The fill includes local serpentine rock (the natural source of NOA and metals). The rock is present throughout the Bayview Hunters Point community and many other areas of California.

For these reasons, dust control is a high priority while soil-disturbing work at the site is underway. It’s also why, after soil cleanup is complete, a protective cover is installed to protect the community from airborne matter.

 

Satisfying safety requirements

Depending on the task being performed, workers wear personal protective equipment, which may include:

  • Gloves
  • Goggles
  • Overalls
  • Respirators

 

These and other worker safety practices at the site meet all relevant requirements of the Occupational Safety and Health Administration (OSHA) and other regulatory agencies.

Because of the presence of NOA in the area, the remedy for the site included the installation of a protective cover after soil cleanup was complete. A protective cover is now in place throughout the site. The only area where a cover is not in place is Area H. This portion of the property was never filled and was never used for PG&E power plant operations. Area H was reseeded with native plants.
