Tracy Material Recovery&Transfer Station SPCC Plan Shop Area Five ASTs are located at the shop area(one 1,500 gallon used oil,two with 250 gallon hydraulic oil, one 250 gallon motor oil, and one 250 gallon transmission oil).The tanks and some drums are located under an exterior covered canopy with a concrete-bermed containment area possessing several hundred gallons capacity. Other stationary drums are located on secondary containment pallets. Some drums may be in mobile units that provide limited secondary containment. There is a storm drain located outside the shop over 80 feet east of the tanks. In order to promptly respond to spills, absorbent materials and equipment are readily available in the shop and spill carts are stationed near work areas where chemicals are located. The used oil AST is located outside the shop and is double walled with an overfill protection alarm. It is used to accumulate used oil from small containers used to drain the oil from the trucks. Oil is added to the tank either manually by pouring the container into the tank or using the installed suction pump to siphon oil from the floor container into the tank. Overfills, hose leaks during tank unloading, or other spills from used oil collection activities would be contained at the tank area. The nature of the operations makes a high level alarm unnecessary. The four product ASTs are located adjacent to the used oil tank within the concrete containment area. Hoses from the tank provide delivery of product oil to various work stations in the shop. Shop personnel will insure that the product pumps are turned off at night to prevent spills during non-operational hours. MRF/TS Building An industrial baler located in the MRF/TS building contains a 1,500 gallon AST for hydraulic fluid. This AST is constructed of heavy steel and resides within the baler unit; it is single-walled and located beneath recycling equipment which is out of any traffic area.The potential for a rupture of this AST is remote, but at this volume, much of its contents would undoubtedly reach the onsite drainage system and, ultimately, the retention basin as the building provides limited secondary containment. Should a rupture occur, the spill management contractor would be required to remove the contents of the retention basin and conduct extensive clean up at the site. The potential for discharge from the baler AST is more likely to occur from a leaking hose which would be managed by onsite personnel utilizing spill kit equipment located in the MRF/TS building. Stationary drums storing used oil, waste antifreeze, and waste cooking oil are located on secondary containment pallets. There is a storm drain located outside the shop approximately 140 feet northeast of the roll-up door adjacent to the drums. In order to promptly respond to spills, absorbent materials and equipment are readily available in the MRF/TS building and spill carts are stationed near work areas where chemicals are located.
