g. DESCRIPTION: PG&E was conducting an excavation to repair and replace a natural gas pipeline. During the backfill process, construction crews noticed water bubbling up in the soil which was determined to be coming from a water line. The cause of the release is unknown. The release impacted the soil and two storm drains. Storm drain covers were in place to reduce sediment impact to the storm drain. It is unknown where the storm drain leads. The owners of the water line responded and stopped the release within two hours. The repair has been completed.
