Chino Hills State Park

SoCalGas is dedicated to maintaining the safety and integrity of our natural gas pipelines. We routinely perform various pipeline maintenance and safety tasks, including patrolling, inspecting, testing, repairing, and replacing pipelines. Enhancing our system helps us to continue to reliably provide the natural gas service that our customers count on. Natural gas is critical to providing an affordable and reliable energy source for heating and cooking to homes and businesses.

We will be in your neighborhood for a hydrotest project that is expected to take four to four months.

You May Notice a Natural Gas Odor

To perform this work safely, the operation may require a controlled release of natural gas. We encourage anyone who has concerns to call us at 1-800-427-2200. 

We strive to provide continuous natural gas service for our customers while the construction activities are taking place. Your natural gas service should continue without interruption. If that changes, a SoCalGas representative will notify customers.
