Playa del Rey Natural Gas Storage Operations

Southern California Gas Company (SoCalGas) continues to operate the Playa del Rey field with the safety of our neighbors as a top priority. In an effort to better update and inform the residents and businesses around our facility, SoCalGas has agreed to implement several measures.

  1. Soil gas monitoring
    SoCalGas will set up a soil gas monitoring program using a qualified consultant agreed to by the CPUC and establish a procedure to post results of the soil gas monitoring analysis. Results will also be provided to the CPUC’s Utilities Safety and Reliability Branch (“USRB.”) We will also follow a soil gas monitoring program after abandoning and closing any wells.
  2. Subsidence monitoring
    SoCalGas will set up a program to monitor subsidence in the area. Subsidence is a phenomenon where the elevation of the ground is lowered over a large area. In some parts of the Los Angeles basin this has resulted from large scale withdrawal of oil or water from subsurface formations. SoCalGas will hire a specialized contractor to monitor for the occurrence of subsidence using sophisticated satellite technology that is capable of detecting changes in ground level of 2 to 3 millimeters. We will also submit results of this program to the USRB and post results.
  3. Gas pressure, withdrawal and release of liquids
    In the Venice area of the field, we will continue to maintain reservoir pressure at no greater than 2400 psi.
  4. Withdrawn Gas Composition
    The chemical composition of withdrawn gas will be posted and updated monthly.
  5. Testing of liquids 
    If SoCalGas releases any liquids into the atmosphere that reach neighboring homes, we will test the liquids for Polychlorinated Biphenyls (PCBs), metals, and volatile organic compounds (VOCs). These results will be posted. PCB content of liquids collected inside of our pipeline at the facility since 2003 and going forward will be posted.

Soil Gas Monitoring

Out of 150 points sampled utilizing 4' deep probes in Phase One, 2 locations (involving 5 sample points) yielded methane levels higher than 25,000 PPM. As per the Settlement Agreement approved by the CPUC, this requires immediate investigation (Phase Two) with 2 - 20' deep probes at the two well sites where gas was found -- and more extensive testing of the samples obtained. Once those results have been obtained, then it will be determined whether the gas is associated with the Storage Field and what, if any, further action is required.
