Sign Up For Proposition 65 Warnings Activated by the SoCalGas Aliso Canyon Fence-Line Monitoring System

Click on the Appropriate Button Below to Get Warnings by Email or Text Message.

SoCalGas is providing the opportunity to receive an email or text message with a warning when the fence-line monitoring system at the Aliso Canyon Gas Storage Facility detects methane in the air in excess of 25 parts per million for 30 minutes, followed by a detection of benzene at a level of 1.5 parts per billion or greater averaged over any 30-minute period.

The warning does not necessarily mean that you have been exposed to benzene from the facility. Distance from the facility, wind direction, meteorological conditions, and topography all play a part in whether there would be concentrations of benzene high enough to cause an exposure at a specific location. If a warning notification is issued, you are encouraged to check the alisocynalerts.sonomatechdata.com/warnings for more information on the nature and timing of the exceedance. These warning notifications are provided pursuant to California’s Proposition 65 and are similar to warning notifications you may be familiar with at gas stations, parking garages, and other locations.
