## Development of Chemical Precipitation Purchased Equipment Costs: **Tanks**
Purchased Equipment Costs are the sum of the following cost elements: (1) Pump Costs (2) Tank Costs (3) Chemical Feed Sy stem Costs (4) Mixer Costs (5) Clarifier Costs (6) Filter Press Costs (7) Sand Filter Costs

This Excel workbook consists of the following worksheets:

FRP vs Steel

Shop-built steel tanks

Field-built steel tanks **Legend** Develops a relationship between tank volume and field-built tank and freight costs. Additionally , internal surface area is calculated for use in developing coating costs.

Vendor provided data. See DCN SE01825.A17 for data used as the source for these analy ses. Vendor provided data. See See DCN SE01825.A14 for data used as the source for these analy ses. Each cost component includes the cost of freight and associated ancillary equipm ent such as piping, valves, and controllers.

This Excel workbook documents EPA's derivation of cost element (2) using information provided by industry vendors.

EPA determ ined carbon steel tank costs for each plant using the equations derived in this workbook. EPA determined whether carbon steel or FRP tanks would be used for each ty pe of tank based on the cost and detailed comparisons documented in this workbook.

Develops FRP tank costs and compares them to carbon steel tank costs developed in the following worksheets. FRP tank costs are based on phone conversations with a vendor documented in DCNs SE01825.A10 and A12. A cost per gallon is used to compare the tanks. Develops a relationship between tank volume and shop-built tank and freight costs. The coating cost equation developed in the subsequent worksheet is also applied to develop total costs.Develops a relationship between tank volume and field-built tank and freight costs.
