California Extends Vapor Intrusion Review Due to Virus

March 26, 2020, 9:25 PM

Health concerns over the new coronavirus pandemic have prompted California regulatory agencies to extend the comment period and postpone public meetings about new instructions for screening and evaluating vapor air intrusion.

  • Vapor intrusion happens when toxic vapors move through soil to the surface. Gasoline, diesel fuel, and solvents used in dry cleaning are common sources. Some chemicals are carcinogenic.
  • California’s Department of Toxic Substances Control, the State Water Resources Control Board, and the San Francisco Bay Regional Water Quality Control Board developed the additional guidance.
  • The comment period had been extended to noon June 1. April public meetings have been postponed indefinitely.
