1 <br />' l0. Drains and outlets on tank trucks are checked for leakage before departure. The <br />drivers aze trained in this procedure by their employer. When the storage tank is <br />' unloaded, the drivers chocks the truck wheels prior to loading and removes [he <br />chocks only after ascertaining that no lines are left connected to the unloading <br />apparatus. <br />' 11. The facility is in such a location that if a major spill were to occur it would be <br />directed to the surface facility detention pond via road borrow ditches. Listed below <br />' are possible spill scenarios: <br />Vehicle Maintenance Shop used oil tank - <br />a. Transfer of liquid from 5 gallon bucket to the tank. Maximum spillage <br />estimated at 5 gallons. The spill would spread out on the gravel surface <br />' and be absorbed by the gravel. Sufficient absorbent materials are <br />available on site to handle spills of this size. <br />b. Transfer of tank contents to tanker for off-site use. Maximum spillage <br />estimated at 5~ gallons. Spill would spread out on gravel surface and be <br />absorbed. Sufficient absorbent materials are available on site to handle <br />spills of this size. <br />c. Maximum capacity spill by container rupture. Maximum spillage is 55 <br />' gallons. This quantity would be contained within the steel containment <br />vessel. <br />' If the steel containment vessel were to ever accumulate sufficient water to make <br /> drainage of the area necessary, a portable pump would be utilized to remove the <br /> water. Careful observation of the water surface prior to pumping and discharge into <br />' the storm water drainage system will ensure that no discharge of oil occurs as <br /> prohibited by 40 CFR Part 1103. If drainage of the containment azea should ever be <br /> necessary, documentation of the inspection or sampling of the water prior to <br />' discharge will be kept on file at the facility. <br />1 <br /> <br />1 <br />1 <br />1 <br />14 <br />
