TOC has been in the process of obtaining the necessary permit, via Permit by <br /> Rule, now known as Tiered Permitting, for their carbon filter-bed treatment <br /> system. The tier they will be classified under will be the Conditional Exemption <br /> for specified wastestream. TOC is still working with DTSC on this process, as <br /> they have only completed phase I of the procedure. <br /> V. GENERAL DESCRIPTION OF FACILITY: <br /> TOC is located in the Port of Stockton at 3015 Navy Dr., and has been at this site <br /> since December 1948. The facility serves as a bulk loading terminal for tanker <br /> trucks transporting fuel. The terminal is a 24 hour operation and currently <br /> employs four full time employees. <br /> VI. HAZARDOUS WASTE ACTIVITY DESCRIPTION: <br /> 1. TOC generates antifreeze contaminated with water from their "knock out" <br /> tank associated with refueling trucks. In approximately January of 1993, <br /> this system was modified such that pure water is "pulled off', resulting in <br /> less volume of hazardous waste generated. In 1992, TOC generated .98 <br /> tons of waste ethylene glycol, and it was hauled to P R C Patterson, Inc. <br /> (PRC) 13331 N. Hwy 33, Patterson, CA 95363. <br /> 2. TOC has a 4000 gallon sump associated with their tank loading rack. This <br /> sump is used to collect storm water run-off, truck wash run-off, incidental <br /> spillage, etc. In February of 1992, the sump was cleaned which resulted in <br /> 3.39 tons of waste hauled to PRC. From the sump, the fuel/water mixture <br /> is pumped to an aboveground oil/water separator. The waste generated <br /> from the sludge removal and cleaning of the oil/water separator for 1992 <br /> totaled 91.59 tons and was disposed of by PRC. (The separator was <br /> cleaned to allow for maintenance on the system as well as the function <br /> described below in #3.) The resulting effluent from the separator is passed <br /> through a series of drummed carbon filters and the remaining fluid waste is <br /> discharged, under permit, to the sanitary sewer. The waste carbon filters <br /> generated during this process are hauled as hazardous waste. TOC <br /> generated one ton of waste carbon filters in 1992, and this waste was <br /> disposed of by U.S. Ecology, Hwy 95, Beatty, NV 89003 and American <br /> Environmental Management (AEM) 11855 White Rock Rd., Rancho <br /> Cordova, CA 95742. <br /> 3. TOC generates hazardous waste during the cleaning of their aboveground <br /> tanks. This activity is performed by a third parry company as needed, and <br /> at least routinely every five years. The oil/water separator, referred to in <br /> #2 above, is occasionally used in this activity as it actually consists of two <br /> separate tanks. Each tank is 8,000 gallons in capacity, with the northern <br /> one performing the separation and the southern tank acting as a storage <br /> unit. The storage side is used either for overflow from the separator, or to <br /> temporarily store the contents of an aboveground tank during its cleaning. <br /> 3 <br />
