Southern California Gas Co. unveiled a new methane capture system to save released gas from pipeline replacement work for later use, part of its pipeline safety enhancement plan.
The system would be used in a pipeline replacement project in west Los Angeles, and the utility expects to capture about 190 Mcf of gas in the process, according to a March 25 news release.
In addition, the utility introduced an interactive online tool allowing the public to view methane monitoring data at its Aliso Canyon gas storage facility. The new web page is one of SoCalGas' latest technology and safety enhancement efforts, which include round-the-clock pressure monitoring and infrared thermal imaging cameras for leak detection.
"This new tool will offer the community near real-time information about methane levels at the facility and will supplement a single methane monitoring station operated by the community," said Lisa Alexander, vice president for customer solutions and communications at SoCalGas.
On March 20, a pipeline leak much smaller than the massive breach in late 2015 was discovered at Aliso Canyon and immediately plugged on the same day it was discovered. "The release was minor and did not pose a risk to safety, health or the environment," a SoCalGas spokeswoman said.
Under its pipeline safety enhancement plan, SoCalGas is to pressure-test or replace certain high-pressure pipeline sections in its system and upgrade, replace or retrofit mainline valves for remote control or automatic shutoff. The utility has a five-year capital plan with $6 billion budgeted for infrastructure improvements and about $1.2 billion for pipeline safety, distribution, transmission and storage system improvements in 2017.
