L- --_..J MSA 9800 Shelard Parkway, Suite 102 Minneapolis, MN 55441 Re: Proposal to Inspect a 500 MG Hydropillar City of Arden Hills, Minnesota AEC Proposal #MN062992 Dear Ms. Arlig: We are pleased to submit this proposal to inspect the 500 M G Hydropillar for the City of Arden Hills. Minnesota in the Fall 1992. The inspection will be performed in conformance with the applicable sections of the enclosed . Procedures For Insoectina Existina Steel Water Storaae Tanks. Please note that the owner is to provide an operator to control the flow rate from the reservoir. This person must be at the control station full time while our inspectors are inside the reservoir. This is a safety precaution so that in an emergency, the flow from the reservoir can be stopped immediately. The interior will be examined by one or two individuals floating in a raft while the reservoir is being emptied. This evaluation can only be performed if the temperatures are above freezing and there is no ice in the reservoir. The exterior will be examined in areas accessible without any rigging or scaffolding. Paint chips from the exterior coating will be analyzed for total lead content. Based on the results, we may recommend a TCLP Test be performed on a sand blasted sample to determine if removal of the exterior coating will generate hazardous waste. Following the inspection, we will submit an Inspection Report, certified by a professional engineer. The report will include color photographs of the conditions discovered during the inspection, engineering analysis, and cost estimates of any reconditioning work required. The report will also include necessary repair procedures for an existing leak, Two copies of the report will be provided. The reservoir inspection will be done for a fixed fee of $2.000.00, including the certified Inspection Report and initial paint chip test for lead. If the inspection cannot be completed in one day, each additional day will be charged at $850.00. The inspection fee does not include the cost of the TCLP Test. AEC provides this service and a cost estimate will furnished upon request. .
