Narrative
On may 8th, 2017 a leak was discovered near 6205 archibald ave. In rancho cucamonga. Responding socalgas crews located the leak on a aldyl-a plastic 2 inch coupling and affected a repair. No injuries or further damage resulted from this incident. Investigation immediately following the leak repair revealed elevated methane concentrations in the soil surrounding the repaired leak. Crews began to perform vacuum extraction of residual gas per gas standard 184.0426 mitigation of persistent residual gas indications. Extraction operations continued, including the use of contractors, until methane concentrations were returned to normal concentrations. Extraction equipment was removed from the site wednesday june 7th, 2017. Post extraction monitoring continues for 6 weeks until july 19th, 2017 to verify methane concentrations remain at normal concentrations. This incident was reported to the cpuc due to media coverage of gas extraction operation on may 18th. This incident was reported to PHMSA on june 13th, when claims of property damage estimates began coming in, and it was determined those could potentially exceed the $50,000 threshold. When those costs are finalized, a supplemental and final report will be submitted or rescinded as appropriate. Note: the gas loss calculation was based on the time socalgas identified the leak until the time gas was controlled. 12-26-18 - supplemental report submitted with final costs.
