Dear North San Fernando Valley community member:

Over the next couple days you may notice a small plane flying at low

altitudes over our Aliso Canyon natural gas storage facility. The flights

are being conducted to measure background methane levels at the

facility and are a required step in the process to resume natural gas

injections.

As described in our last communication, the flights are one of several

checks and activities that must be completed before SoCalGas can begin

to resume injections. A complete list of these activities is available here.

As we move through this process, we will continue to provide updates

on our progress at socalgas.com/alisoupdates. We will also continue to

provide periodic email updates to the community.
