MAIN STREET RECOMMENDATION: Request the Tustin City Council, at their regular meeting of June 16, 1986, to authorize the removal of the 500 gallon underground storage tank located at 235 E. Main Street by Kamtec Corporation for a cost of $6,230+. BACKGROUND: On. January 1, 1984, the State Underground Storage Tank Law became effective. The purpose of the law is to regulate underground tanks containing hazardous materials in order to protect the groundwater and public health from the effects of leaks from these tanks. The law imposes several requirements on owners of underground tanks, including the application of a permit to operate and the implementation of an approved method to monitor the underground tanks for leaks. The law also makes provisions for tank removal. The City currently has three 12,000 gallon each underground fuel tanks located at 1472 Service Road. This amount of storage is sufficient to satisfy the needs of the City of Tustin and the Tustin Unified School District at this time. The tank recommended for removal is a 500 gallon steel tank located underground at 235 E. Main Street. Staff is recommending this tank be removed for several reasons: 1) adequate storage exists for all City use at 1472 Service Road; 2) this tank is of such an age, that the cost to bring it up to the minimum standard required by the law would be prohibitive; 3) the tank is located on the same property as a water well. Because the City does not have staff licensed to perform the required work, requests for proposals were sent to seven firms in the local area capable of performing the work. Kamtec submitted the only proposal, however, others responded stating that their current work load prohibited them from performing the work at this time.. JUNE 10, 1986 PAGE TWO The cost of $6,230 is for: preparation of state required permits; tank removal; backfilling and paving; testing associated with tank removal; disposal of tank removed; and, submittal of state reports. There may be other costs which are undeterminable at this time. While this tank has not been filled in quite some time and presumed to be empty, there is no way to be certain that it is completely empty. Upon removal from the ground, if it is found that the tank still contains any liquid or sludge, an analysis of the remaining liquid or sludge must be performed by a state certified laboratory. The cost for this analysis will be $400-$600. The remaining liquid or sludge would need to be disposed of at a hazardous waste site. This process will be at actual cost plus 20 percent. If the surrounding soil should be contaminated, it must also be disposed of at a hazardous waste site. Once again, the charge for this process would be actual cost plus 20 percent. Costs for this work may be totally reimbursable from state and federal agencies, but we will not be advised of the reimbursability for this project until December, 1986 or later. Monda Buckley ?
