ITEM #5 CITY OF COLTON AGENDA REPORT FOR THE CITY COUNCIL MEETING OF NOVEMBER 4, 2008 TO: HONORABLE MAYOR AND CITY COUNCIL MEMBERS FROM: MARITZA TAPIA, INTERIM PUBLIC WORKS DIRECTOR SUBJECT: APPROVE CHANGE ORDER NO. 1 AND AUTHORIZE FILE AND RECORDATION OF THE NOTICE OF COMPLETION FOR THE FOR THE FUEL TANK REPLACEMENT PROJECT. DATE: OCTOBER 27, 2008 BACKGROUND: At the City's Corporate Yard, fuel depot underground storage tanks (UST) were installed in 1989. There are a total of five (5) tanks onsite with the following capacities: 12,000 gallons gasoline, 8,000 gallons diesel, 550 gallons oil, 550 gallons hydraulic, and 550 gallons used oil. In conjunction with new regulatory requirements established by the State Water Resources Control Board, the City was notified that the Corporate Yard USTs are within 1000 ft. of a fresh water drinking well and are subject to annual Enhanced Leak Detection Inspection. On December 7, 2007 and July 28, 2008, the County Fire Department Unit performed inspections and found the existing USTs did not comply with the new regulatory requirements. The City secured a permit from County Fire Department for the removal of these tanks which requires these tanks be removed by December 13, 2008. Simultaneously, staff has moved forward in installing an above ground storage tank to service the City's fleet, which does meet the new standards set by the State Water Resources Board. The new above ground tank will have the capacity to hold 8000 gallons of gasoline and 4000 gallons of diesel. Design plans for an above ground storage tank (AST) at the city's corporate yard were completed by Cornerstone Technologies Inc. The regulating agency for an AST installed at the city's Corporate Yard will be the Colton Fire Department, rather than the San Bernardino County Fire Department. The designed AST HAS replaced the existing UST, thereby removing any threat of contamination to fresh drinking wells. ANALYSIS/DISCUSSION: On February 5, 2008, the City Council authorized the award of construction contract for the Corporate Yard Fuel Tank Replacement Project to West Tek, Inc. A `Notice to Proceed' for the above noted project was issued on June 5, 2008. West Tek, Inc. completed the project satisfactorily as specified on contract documents, plans, and specification as of October 15, 2008. The completed project totaled $187,818, which is $12,818 higher than the awarded contract of $175,000. The additional expenses were a result of the following requests by the city: installation of one (1) additional gasoline fuel dispenser, sump box outlet in the spill containment area that will connect to
