These regulations establish construction standards, monitoring standards and closure requirements on all underground storage tanks. The regulations required total compliance with these standards by September 1, 1986. The County Health Department, who is charged with enforcement in San Diego County, has advised us that, because of the extremely large number of underground tanks in the County, it was impossible to have Countywide compliance by that date and that if an underground tank owner has an action plan in effect to meet the regulations and are diligently pursuing that plan, they will cooperate. RECOMMENDATION: That the City Council approve the plan to abandon and remove eight underground fuel tanks, install two new underground tanks and appropriate $94,000 from unappropriated General Fund reserves. BOARDS/COMMISSIONS RECOMMENDATION: Not applicable. DISCUSSION: The City of Chula Vista owns 11 underground storage tanks as follows: 1. Public Works Yard - 10,000 gallon diesel 2. Public Works Yard - 12,000 gallon unleaded gasoline 3. Public Works Yard - 10,000 gallon leaded gasoline 4. Public Works Yard - 550 gallon diesel, not being used 5. Public Works Yard - 550 gallon kerosene, not being used 6. Public Works Yard - 550 gallon waste oil 7. Police Department - 4,000 gallon gasoline 8. Fire Station No. 1 - 1,000 gallon diesel 9. Fire Station No. 1 - 550 gallon gasoline 10. Fire Station No. 2 - 550 gallon diesel 11. Fire Station No. 3 - 550 gallon diesel In addition, there is at least one underground tank at the Golf Course. According to the City's lease agreement with American Golf, the lessee is responsible for this location. The lessee is not using the old tank and is in the process of removing and replacing it. Page 2, Item 8 Meeting Date-1TIT87$6 Tank numbers 1, 2 and 3, above, have been tested as required by the regulations, certified to be safe and the permit applied for to the County. In addition, a tank at Fire Station No. 4 was found to be leaking last spring, the tank and contaminated soil removed, and the site is in the process of being restored. The cost to complete the work to date is over $20,000 and could spend up to the budget amount of $55,000. In order to meet the requirements of the law, we still have to take some action on tanks 4 through 11. There are several options for insuring compliance: 1. Test the tanks and develop a monitoring program. 2. Clean the tanks and fill with concrete leaving them in place. 3. Remove the tanks. It cost approximately $500 each to test the three tanks in the Public Works yard. If any of the tanks were found to be 1 eaki ng, they woul d then have to be removed along with any contaminated soil. If the tanks pass the test, a monitoring system must be set up and the tanks retested annually. All of the tanks are 20 years or more old and are all single wall steel. This is the same type of tank that developed a leak at Fire Station 4. Because of the similarity in the tanks to the one formerly at Fire Station No. 4 in age and type of material, these tanks could develop leaks at any time. The cost of a monitoring system on the two larger tanks could also be expensive, involving monitoring wells or some other type of observation pit. The tanks could be abandoned according to either option 2 or 3. Option 2, cleaning and filling with concrete, has some negative aspects. First, the tanks have to be cleaned before filling. Second, if the site were ever sold, or we wished to build on that location, the tanks would have to be removed. The cost of removing a large block of concrete could be prohibitive. Third, test boring of the soil under the tanks would have to be taken and analyzed to determine whether or not the soil is contaminated. If it is, those tanks and the soil would still have to be removed. Under Option 3, tank removal, the County Health Department would visually inspect the tank as it is removed and check the soil for contamination. Any contaminated soil would still have to be removed, however, we would not have had the tank cleaning and soil boring costs. Because of the potential for leaks and future removal costs, it is recommended that all the tanks be abandoned and removed. The estimated total cost to remove the 8 tanks is $54,000. This estimate assumes no leaks have occurred and no additional soil needs to be removed. Both the Police Department and Fire Department require at least one alternate fueling facility. The Police Department requires an alternate facility on a 24-hour basis in the event the Public Works Yard is not available, either through an equipment failure or power outage. Page 3, Item 8 Meeting Date 11 18 86 The Fire Department requires at least one alternate fueling facility more centralized to the outlying stations. Requiring all the fire trucks to come into the Public Works yard to fuel creates coverage problems for the Department every time a truck must be refueled. In order to meet the Police and Fire Departments' needs, there are several options available: 1. Issue credit cards for 24-hour stations. 2. Install two new double-walled 1,000 gallon underground tanks at Station 2 which meet all the monitoring requirements. One tank would supply the Fire Department with diesel and the other the Police Department with gasoline. The estimated cost for this installation is $17,000 to $20,000 for each tank. The first option has been ruled out because of the difficulty in limiting unauthorized use of credit cards and controlling the purchases. In addition, there are no 24-hour stations in Chula Vista selling diesel fuel. If the first option is not feasible, then it will be necessary to install new tanks meeting all the current standards at Station No. 2. Two locations are desirable; however, due to the high cost of the installation, one location could work. The waste oil tank at the Corporation Yard will be replaced with several 55-gallon drums to store the product until it can be picked up by the waste oil collector. Staff is also cognizant of the potential for a change in the future location of the Public Works Yard. While the future location is not known, it will probably be located east of I-805. The fueling facilities at Station 2 would then provide a location west of I-805. It should also be mentioned in connection with this item that there is a plan to have fueling facilities at the new Fire Station to be constructed on East "H" Street, approximately one mile west of Otay Lakes Road. This construction is proposed for sometime in the next 3 to 5 years. FISCAL IMPACT: The estimated cost to remove all eight tanks is $54,000. To install two new underground tanks at Fire Station No. 2 is $40,000. The total required is $94,000 assuming none of the tanks have developed leaks. There are no funds budgeted.
