<br /> . , <br /> .. <br /> . CITY OF ARDEN HILLS <br /> JmDWID(lM <br /> DATE: NoV8Dber 24, 1992 <br /> TO: Dorothy PersOn, city Mministrator <br /> FRCM: DIm winkel., Public works superint........~t <br /> SllBJECT: Remaval of 10,000 Gallon Gasoline Tank <br /> I am requesting that the Council approve the rerooval of the 10,000 gallon <br /> gasoline tank located behi.rrl the Public Works J:uildi.nq. ihe tank was <br /> originally scheduled to be removed in 1991. D..1e to the possibility of <br /> including the rem:wal costs in the proposed new Public Works facility, it was <br /> my recommendation not to remove it in 1991. However, as the preparation of <br /> the 1993 Budget began, which includes an estimated cost for spending in 1992, <br /> it became obvious that the tank rencval should be added back in the 1992 <br /> Budget if the referendum fails. ihe Council agreed and said that the tank <br /> shall be removed this year. There is $10,000 in the 1992 estimated I::udget for <br /> rem:wal of this year. <br /> . I have obtained three quotes to do this job. '!be tank rencval shall include; <br /> rerooving the tank and hauling to an approved tank disposal company for <br /> disposal, purging the tank prior to rerooval, backfillin:J the site to grade, <br /> and also conducting the required envirornnental site assessment with written <br /> report for a clean site. The quoted prices for this specification are as <br /> follows: <br /> 1. Minnesota Petroleum Service, Inc. $3,878.00 <br /> 2. Griffin Service 4,350.00 <br /> 3. Petroleum Equipment Services 4,040.00 <br /> Minnesota Petroleum is the apparent low bidder for this project. Mr. Bruce <br /> Madsen from Minnesota Petroleum stated that he could get this done yet this <br /> fall. <br /> There are also alternate costs that may be encountered during this tank <br /> removal. These costs were foun:l on site durin:J the tank removal. These costs <br /> include the excavation, rencval and stockpilin:J of bnpacted soil at $6.18 per <br /> cubic yard. I.oaclin] and haulin:J the bnpacted soil to a disposal site would <br /> cost $8.05 per cubic yard. And finally addin:J clean replacement soil <br /> c:arrpacted in place would cost $11.50 per cubic yard. It is my hope that these <br /> extra costs would not be needed, and if they are that we could reduce some of <br /> the costs by our people loading the tnlcks to haul the material away. <br /> REXX1'1MENDATION: <br /> . It is my recommendation that we hire Minnesota Petroleum to remove the <br /> un:lerground gas tank, and that they be authorized to do this as soon as <br /> possible. <br /> I:M/ts <br />
