Southern California Gas Aliso Canyon Progress Update

Relief Well Operations Advancing On-Schedule into Fourth of Five Phases; Efforts to Alleviate Community Concerns, Reduce Emissions Continue

LOS ANGELES, Jan. 13, 2016 /PRNewswire/ -- Southern California Gas Co. (SoCalGas) continues to work as quickly and safely as possible to stop the natural gas leak at its Aliso Canyon Storage Facility while reducing the odor reaching the community.  The update below covers events and activities for the time period January 4-13, 2016.  More information on the topics below is available by calling the media hotline at (877) 643-2331 or visiting

Resident Relocations Continue
As of Jan. 13, SoCalGas has relocated 2,479 households and is continuing to work with 1,581 households in different stages of finalizing arrangements. SoCalGas is also offering pet boarding upon request for relocated families, and families who chose not to relocate but remain in the Porter Ranch 91326 zip code.

Progress on the Stopping the Leak—Relief Well in Phase 4
The relief well efforts are now in Phase 4, the "Follow" phase, and drilling is occurring at more than 7,600 feet as of Jan. 13. The objective of this phase is to maintain the proper distance and angle to the target well, while following it down to below 8,000 feet of measured depth using active magnetic ranging. This phase will put the relief well into position for the final phase of intercepting the target well. This phase will be one of the longer phases because the drilling crew has to gradually work its way down to below 8,000 feet of measured depth by alternating between drilling and ranging. This effort requires the drilling equipment to be retracted and exchanged with the ranging equipment, which can take a day for each process. Ultimately the relief well will intercept the leaking well at more than 8,500 feet below the surface. Fluids will be pumped in to stop gas flow, followed by cement, which should permanently seal the leaking well off from the natural gas reservoir. 

The relief well process is scheduled to be complete sometime between late-February and late-March. A fact sheet on the relief well can be found on the SoCalGas newsroom: All work continues in conjunction with multiple agencies including: Los Angeles County and City Fire, California Office of Emergency Services, Division of Oil, Gas and Geothermal Research (DOGGR), the California Public Utilities Commission (CPUC) and California Occupational Safety and Health Administration (CalOSHA), to oversee the operation and worker safety.

Sen. Fran Pavley's Legislative Proposals
The initiative announced this week by Sen. Pavley and other legislators, represents the start of a legislative process.

SoCalGas appreciates the legislators' interest in the topic and looks forward to participating in the public discussion.  As we have since this incident began, SoCalGas stands willing and ready to cooperate with the Governor's office, all state and local officials, and regulatory agencies.

Air Quality and Public Health Information
The most recent Aliso Canyon preliminary methane emissions estimates by the California Air Resources Board (CARB) were posted Jan. 11, showing updated rough estimates of the volume of gas leaking from the well that indicate emissions have decreased from CARB's initial preliminary estimates, SoCalGas announced yesterday.  This new posting represents an estimated 60-percent reduction in CARB emissions estimates since the Nov. 28 data, according to the latest CARB monitoring data, and an approximate 20-percent reduction in emissions estimates since the most recent Dec. 23 preliminary estimate by CARB. 

SoCalGas continues to conduct twice daily air sampling both at the leak site and within the community. Results are posted on its website.

The California Office of Environmental Health Hazard Assessment (OEHHA) has completed its review of the available data and has noted that "...the available Porter Ranch neighborhood air sample data does not indicate that an acute toxicity health hazard exists in the Porter Ranch neighborhood due to the Aliso Canyon natural gas leak." More information can be found on the OEHHA website.

Also, according to the Los Angeles County of Department of Public Health, (LA County DPH) Aliso Canyon Gas Leak Health Fact Sheet, Mercaptans, the odorant in the gas emitting from Aliso Canyon, may cause eye, nose and throat irritation, coughing and nasal congestion, shortness of breath, nausea, stomach discomfort, dizziness and headaches.  A number of the residents of Porter Ranch have reported experiencing one or more of these symptoms.  However, according to the LA County DPH, this odorant is not associated with long-term health effects, though symptoms may recur on a daily basis as long as the odors remain.

Schools Back in Session
SoCalGas is committed to minimizing the burden on Porter Ranch residents and will work with LAUSD to provide support where needed. Porter Ranch residents who have been temporarily relocated can consider the following school transportation options for their children: bus transportation, mileage reimbursement or alternative transportation.  For details, visit

SoCalGas Appears at Jan. 9 AQMD Hearing
SoCalGas appeared at the Jan. 9 hearing before the South Coast Air Quality Management District Hearing Board and has agreed to the stipulated abatement order that the Hearing Board will consider on Jan. 16. SoCalGas stands ready to implement its requirements just as soon as the Hearing Board takes final action.  Among other directives, the order requires SoCalGas to collect and treat gas leaking from the well to the extent that it can be done safely. It also orders SoCalGas to fund additional air monitoring, to further enhance well inspections and fund an independent health study.

SoCalGas recognizes that expert public agency involvement and oversight is essential to assuring neighbors, customers and the general public that this accident is being addressed as safely and expeditiously as possible.  This is SoCalGas' highest priority.
