SAN JOAQUIN COUNTY N: ENVIRONMENTAL HEALTH DEPARTMENT :. ►;� 600 E Main Street Stockton - CA 95202 (209) 468-3420 • Fax: (209) 468-3448 • Web: www.siaov.or4/ehd EMERGENCY RESPONSE INVESTIGATION REPORT: (INCLUDE CHRONOLOGICAL HISTORY. RECOMMENDATIONS, CLEANUP and FINAL DISPOSITION) 11/15/10 6:15 PM Received a message from the operator that Mr. Mike Elisason with Valley Pacific Petroleum Services called to report a diesel fuel spill at 3550 S. Hwy 99 Frontage Rd., Stockton. (209) 993-8793. 6:21 PM - I called Mr. Eliason and left a message asking for more information. Mr. Eliason called me back and informed me that Elite IV Contractors was hired to make a repair to dispensing unit 3/4. Elite IV neglected to shut the power off to the pump and a customer lifted a handle which caused the pump to come on and cause the spill. The shear valve on the pipe did not hold. The pump was shut down and the spill was contained with absorbent. The service technician for Elite IV was sprayed with diesel fuel but was not harmed according to Mr. Eliason. The spill did not reach a storm water catch basin. Mr. Eliason stated that they would resume the clean up at 8:30 AM tomorrow. I informed him that I would be on site tomorrow to document the spill. 11/16/10 8:06 AM On site to document the clean up of the spill. Met with Mr. James Abbott, Mr. Dan Elmer and Mr. Nathan Crum who work for Valley Pacific Petroleum Services. They had personnel from the company sweeping up the absorbent that was placed on the spill and containerizing it for pick up later by a licensed transporter. I took several photos of the staining of the spill on the asphalt. The spill extended approximately 100 feet from the dispenser to the east. Staining was also observed to the west of the dispensing area off of the concrete and onto the asphalt. The asphalt has cracks and gaps and is in poor condition. The nearest storm water catch basin is to the south, approximately 200 feet and it flows to a pond to the south east. The dispenser that was being worked on is part of an Aboveground Storage Tank system, so a permit to repair was not required to be obtained. The clean up will continue throughout the day and I requested that personnel come back later in the week to check for weeps of fuel coming out of the asphalt. I also requested that a copy of the waste disposal receipt for the waste absorbent be submitted to me once it has been hauled away from the site. Left at 8:32 AM. Filled out a Prop. 65. 11/22/10 - 11:15 AM Received a call from Wendy Cohen with the CVRWQCB (916) 464-5817 who received my Prop. 65 notification. I informed her of the spill and that it was released from a aboveground storage tank system. I called and spoke with Mike Eliason and asked him for the exact number of gallons that was spilled. He stated that 75 gallons was the estimate upon reviewing the inventory of the tank. Mr. Eliason also had a question about which report he was to submit in seven days. I informed him to contact CALEMA to find out about the follow up reporting and emailed him a link to the CALEMA spill reporting guidelines. I left a phone message with Wendy Cohen regarding the updated gallons of fuel that was spilled. 11/23/10 Received updated CALEMA spill report changing quantity released to 75 gallons.
