4 MEMORANDUM To: Rod Visser,Assistant County Manager From: Paul Spire, Landfill Manager Subject: Estimated Replacement Equipment Needs for Life of Landfill Date: August 27, 2002 Equipment for the landfill is on a designated replacement list that has been in use since the commencing of the landfill as one of its reserve accounts. This schedule lists all the current equipment and anticipates the need for replacement on a set schedule. In the current year of 02-03 there were two things that were up for replacement, one a compactor, which was let out for bid and is suggested for replacement at a cost of$317,000. This compactor has a life expectancy of six(6)years but is expected to be in use till the landfill closes in 2009. The other is a large dump/service type truck that will be purchased off of the state contract, for an anticipated cost of$48,000. The life expectancy of this item is ten(10)years. In 03-04,there is a replacement of a Bulldozer at an anticipated cost of$418,500 with a life expectancy of 6 years,which means that it is to be replaced in the year 09-10. At that time it will be used to put the final cap on the lined landfill and when the cap is completed it will be shitted to the Construction and Demolition Landfill in 11-12. In year 05-06 a wheel loader is to be replaced at an anticipated cost of$119,000 with a life of eight (8)years. This equipment is used in the white goods and tire area of the MSW landfill. In year 06-07 the leachate truck,which is used to haul the landfill's leachate to the processing plant, is up for replacement. It will be replaced on a ten(10)year basis and is to be replaced for the complete monitoring time of the landfill,which is currently for thirty(30)years. The anticipated cost for this replacement is$110,800. It will be replaced three more times before the estimated landfill monitoring time is complete. Also in 06-07 is the motor grader. It is used in the upkeep of the roads and in construction. It is estimated to cost$20,000 (we expect to buy it used off of State surplus equipment) with a life expectancy of eight(8)years and will also change over to the C&D landfill at its next replacement in the year of 13-14. In the year of 09-10 a dozer is replaced which is already listed in the current years (02-03) replacement. Also in that year a hydraulic excavator is replaced. This is used in the white goods,tire, and mulch area of the MSW landfill. It will also be used as a backup to loading the transfer trucks when the transfer station starts. It has an eight(8)year life expectancy and is anticipated to cost $164,000. It should be noted that all estimated replacement cost are true anticipated cost since they are inflated at 3%per year on the previous acquisition cost for each piece of equipment. At current post closure operations the staff will have to monitor and maintain the closed landfill for a minimum of thirty years. This includes all gas monitoring, water monitoring, upkeep of all access roads, maintenance of all erosion control areas, and maintenance of the cap. Maintenance of the cap will consist of checking and repairing of settlement;repairing of seeding and washed out areas, vector control, leachate control,mowing, and general upkeep of the closed landfill. If heavy equipment is necessary to maintain the closed landfill, it will have to come from the Construction and Demolition landfill. Since some of the heavy equipment such as the compactor will not be replaced, other pieces will have to be kept on the replacement list for several years or until such time as the state no longer requires Orange County to monitor its landfill. If you have any other questions please give me a call.
