## Development of Chemical Precipitation Purchased Equipment Costs: **Pumps**

Purchased Equipment Costs are the sum of the following cost elements: (1) Pump Costs (2) Tank Costs (3) Chemical Feed System Costs (4) Mixer Costs (5) Clarifier Costs (6) Filter Press Costs (7) Sand Filter Costs

This Excel workbook consists of the following worksheets:

WW Forwarding

Treated Eff Discharge

Sum p Each cost component includes the cost of freight and associated ancillary equipm ent such as piping, valves, and controllers.

Each worksheet in this workbook derives an equation relating FGD W astewater Flow, gpm to the cost of each required type of pump. FGD W astewater Flow, Pum p Cost, and Pump W eight were obtained from W eir Mineral's cost proposals (DCNs SE01825.A3-A6) and Freight Costs were approximated from FreightCenter.com's online cost estimator (DCN SE01825.A7) using Pump W eight. Pum p Cost was plotted against FGD W astewater Flow and a trendline was added to relate the two. Freight Cost was then divided by the Pum p Cost to develop the Freight Cost/ Pump Cost Ratio. The cost ratio is consistently

between 3 and 5%; therefore, EPA assumed a Pump Freight Factor of 4%. This Excel workbook documents EPA's derivation of cost element (1) using information provided in response to the Steam Electric Survey

and industry

vendors.

EPA determ ined total pum p costs for each plant using the plant's FGD W astewater Flow, gpm in the equations derived in this workbook, the quantity of pumps required, the capacity factor, and the Pump Freight Factor developed in this workbook.

FGD Wastewater Flow, Pum p Cost, and Pump W eight were obtained from W eir Mineral's Wastewater Forwarding Pump proposal (DCNs SE01825.A3) and Freight Costs were approximated from FreightCenter.com's online cost estimator (DCN SE01825.A7) using Pum p W eight. Wastewater forwarding pumps and FGD recycle pumps are costed based on the same data. FGD Wastewater Flow, Pum p Cost, and Pump W eight were obtained from W eir Mineral's Treated W astewater Discharge Pump proposal (DCNs SE01825.A4) and Freight Costs were approximated from FreightCenter.com's online cost estimator (DCN SE01825.A7) using Pum p W eight.
