Tower Park Marina -2- 18 October 1993 <br /> The surrounding area is natural ground, so storm water either soaks into the ground or runs off. <br /> The tanks do not have any water draws. If water is detected in the tanks through their monitoring <br /> systems, a pumper truck would be called to pump the water out. <br /> 3. Some pipes in the tank area need additional support. One pipe was being propped by a 2x4 piece <br /> of wood. A more permanent support is needed for this pipe and other pipes which extend for <br /> some length without supports. <br /> 4. The pipe mentioned in Item 3 had some staining at an elbow joint indicating there is some leakage <br /> at the joint. However, the ground below it was not stained. <br /> 5. One of the fill pipes going into the tanks has a valve with some staining. The ground below this <br /> valve also was not gained. -- - <br /> 6. The pipelines from the tanks are provided with secondary containment consisting of fiberglass <br /> wrapped around the pipes. These pipelines go through the levee to the landside and dock pump <br /> dispensers. The pipelines which go to the docks are connected by flexible hoses from the levee to <br /> the docks. The flexible hoses are needed because of water level fluctuations of as much as ten feet <br /> due to tidal effects. The flexible hoses and the dock pipelines do not have secondary containment. <br /> The dock pipelines are not visible and may be submerged in water. The flexible hoses are partly <br /> submerged in water. <br /> 7. A diesel spill occurred on 23 August 1993. According to the San Joaquin County spill report, a <br /> diesel dispenser on the dock was left open and discharged fuel to the delta. The county <br /> recommended that a separate diesel dispenser system for the park and the docks be provided by <br /> Tower Park. During my inspection, Mr. Johnson stated that the spill was caused by a dispenser <br /> which was indeed left open and also by overfilling. He also said the boat left a trail of floating <br /> product on the delta. He said that after the incident, Tower Park changed from self service to full <br /> service so that only park personnel are allowed to put in fuel. <br /> Mr. Johnson also said that a small spill occurred during the Labor Day weekend. He said the spill <br /> occurred due to a corrosion from the inside of the hose of one of the diesel pumps and since the <br /> nozzle was not open, only what was left in the hose spilled which was approximately less than half <br /> a gallon. <br /> Prior to the inspection, TPM sent me a copy of its Spill Prevention Control and Countermeasure (SPCC) <br /> Plan. My comments on the plan are provided in the attached checklist. <br /> Philip S. Isorena, Associate Engineer <br />
