EMERGENCY RESPONSE INVESTIGATION REPORT INCLUDES CHRONOLOGY,RECOMWENDATIONS,CLEANUP AND FINAL DISPOSITION July 27, 1994 11:50AM Pager notification. I returned to the office to receive the complaint from PHS/EHD and from the Sheriffs office requesting PHS/EHD response. I travelled to Tower Park Marina. 12:20PM I arrived on sight. Already on site were Jerry Yoshioka with OES and Captain Darin Downey and Frank Ruiz with the San Joaquin Delta Fire District. A light sheen was observed in the water around the petroleum dispenser area which is on a dock that floats on the water. Tracy Perkin,Tower Park Marina staff,was just finishing booming off the area with absorbent booms. There was some difficult with obtaining the booms since Tower Park was temporarily out of stock. The area boomed was north of the pier shops and north of the "Bean Shed" board docking area. The tide was moving south and most of the spill was contained within the booms. Jerry and I investigated the extent of the spill and determined that it extended to the south to the 'Carrot Shed",where the slight sheen seemed to dissipate. Yvonne Mabee,Tower Park General Manager,stated that they did not know where the leak came from, though one of her staff indicated that there was a valve at the dispenser that needed to be checked. The spill seemed to be concentrated around the dock area adjacent to the dispenser area. The boat'"The Little Darl'ns"CF 1229HH-Bayliner was moved and it was thought that the shape of the huU allowed the petroleum to collected around the boat. Jim Blain,Tower Park Marina Sales Manager,was very upset and hostile about the boat being moved and brushing up against an adjacent boat. Mike Monez, Tower Park Marina Boat Sales, owner was also on site and observed the activities once the boat was moved. Yvonne Mabee stated that the dispenser was shut off at 8:00 PM last night as usual. 2:15PM GM1 Jim Simmons and BM3 Sean Sasser with the Coast Guard arrived on site. Jim Simmons indicated that the plume did not require any further containment. The individuals on site evaluated possible sources of the spill Tower Park staff was directed by Yvonne Mabee to remove the wood planking above the product lines to visually observe them for any leaks. None were observed. The lines were pressured by turning on the valves and it appeared that the sheen on the water in the dispenser area increased. When the value was closed it appeared that the sheen dissipated. I phoned Doug Wilson,Supervising REHS of PHS/EHD to update and to seek his direction. He suggested that I provide an inspection report with PHS/EHD recommendation that the lines be pressure tested before use. I phoned back and received his approval prior to giving the inspection report to Yvonne Mabee and to the other regulatory agencies on site. 3:00PM Left site. Arrived at PHS/EHD office at 3:40 PM. 1
