Complaint Investigation Summary Report#:5105 COMPLAINT ID: COQXZNQTU Site Location: 800 E PESCADERO AVE Activity Summary Activity Date Recorded by 06/18/2020 5:00 PM- 10:24 PM Continuation from day. ALANIZ Arrived on site and met with Anthony Harb, Safety Manager with McLain Food Service. Also on site was Jim Carroll, vacuum truck worker with ABC Plumbing. ABC Plumbing was hired by All Environmental Services, environmental cleanup contractor, to pump the storm drain sump. Anthony showed me the spill area on the pavement. Diesel staining was observed starting near the center median on Pescadero St. and ending at a storm drain in the McLain Food Service parking lot. The diesel spill on the pavement was adequately cleaned by All Environmental Services. Approximately two 55 gallon drums of diesel contaminated absorbent waste was generated from the pavement cleanup. The impacted storm drain in the parking lot discharges into a nearby canal approximately 15 feet west. A diesel water mixture was observed discharging out of the storm drain pipe and into the canal. Diesel contaminated water was seen one quarter of a mile downstream from the storm drain discharge point. No diesel contaminated water was seen half a mile and three quarters of a mile downstream. Vegetation, fish, and other wildlife were observed in the canal. No dead wildlife was observed. Brandon Espinoza,All Environmental Services, 209-648-8060, arrived on site at approximately 6:30 p.m. Showed him the canal area contaminated with diesel fuel. He said his plan was to put absorbent booms around the pipe outlet and pump out the diesel water from the sump. The impacted storm drain contained a sump before it reached the canal. The cleanup crew attempted to pump the sump with a 1800 gallon pump truck but it did not work because there was too much water. Diesel was still observed in the drain after the truck had been filled. The initial plan was to take the water from the pump truck and put it into 55 gallon drums. It was decided that more equipment and people were needed to conduct a complete cleanup. The plan was revised to plug the drain on both ends of the impacted storm drain. Once this would be done, the piping section blocked off by the plugs would be remediated. According to Anthony, the entire draining system at the facility goes through the impacted storm drain before it reaches the canal. Piping upstream of impacted drain was inspected to make sure the diesel had not migrated the other direction. No contaminated piping upstream was observed. It was decided that the cleanup was going to occur on 6/19/2020 so the cleanup company could secure more supplies and people to assist with the cleanup. Since the cleanup was going to be completed the next day, Brandon had two of his employees come out from other shops with bigger absorbent booms and several totes for the diesel waste water in the vacuum truck. To contain the diesel, a bigger boom was placed around the outlet pipe going into the canal. In addition, a boom was placed in a narrow part of the canal one quarter of a mile downstream where the diesel sheen was very faint and appeared to be the end of the impacted area. This was done to limit the spread of contamination. I inspected an area 1/2 a mile and 3/4 of a mile downstream. Those areas were not observed impacted. All of the waste generated was left on site. Brandon is going to run samples to determine if the waste is hazardous. Called Robert De Leon, Supervisor with DTL Transport, 559-577-6300. Informed him of the EHD process (notice to abate, billing, Prop 65...). Gathered his information and created a complaint. He requested that the notice to abate be emailed to him at<reapairs@dtltransport.com> and asked me to cc 5105.rpt Page 2 of 11
