Piping Cost

Trucking vs. Piping EPA extended the cost estimate to all leachate plants instead of the two sample plants

evaluated on the 'Trucking Costs' and 'Piping Cost' tabs. This tab includes a list of all leachate plants and their wastewater flow rates. Column I includes the estimated annualized cost associated with trucking leachate while column M includes the estimated annualized cost associated with pumping the leachate. This Excel workbook documents the analysis conducted by EPA to determine the most cost effective method for transporting leachate from the collection point back to the equalization tank at the start of the FGD treatment system.

EPA assumes that plants discharing both FGD wastewater and landfill leachate will treat the two waste streams with the same treatment system if limits were to be set on both types of discharge. EPA acknowldeges that this is not feasible for those plants with some level of FGD wastewater treatment already in place, see the leachate and FGD treatment in place analysis. For those plants that find it feasible to treat the two waste streams with one treatment system, EPA conducted an analysis to determine the most cost effective method for transferring the leachate back to the plant FGD wastewater treatment system. EPA considered trucking the leachate and transferring the wastewater by pump and length of pipe (both concrete and stainless steel piping). EPA determined that stainless steel pipe and pump was the most cost effective.

EPA estimated the cost per foot for lengths of concrete piping. Along with the cost of piping, freight costs were also incorporated into the $/foot estimate. EPA determined that freight costs made concrete pipe an unfeasible option due to the weight. EPA estimated the cost per foot for lengths of stainless steel piping. These $/foot estimates were adjusted to include costs associated with freight. Average freight was found to be 0.9% of the purchased costs and is highlighted in yellow. For two plant, 9161 and 9177, EPA estimated the costs associated with trucking leachate from the landfill back to the plant. The costs detailed on this tab assume that the plant will purchase dump trucks to be able to accomplish this task. The costs detailed here follow early revisions of the sludge transportation methodology which included costs for purchasing trucks, insurance, fuel, labor costs associated with the driver, fuel, and general maintenance. EPA estimated the costs associated with purchasing a pump and stainless steel piping to transfer the leachate for the same two plants (9161 and 9177) from the landfill back to the plant. This cost estimate assumes the pumps purchased will be similar to the wastewater transfer pumps costed for the chemical precipitation treatment system.EPA extended the cost estimate to all leachate plants instead of the two sample plants evaluated on the 'Trucking Costs' and 'Piping Cost' tabs.
