## Development of Chemical Precipitation Operation and Maintenance Costs: **Maintenance Labor and Maintenance Materials**

Total operating and maintenance costs are the sum of the following cost elements: (1) Operating Labor Costs (2) Maintenance Labor Costs (3) Maintenance Materials Costs (4) Chemical Purchase Costs (5) Energy

Costs (6) Sludge Disposal Costs (7) Compliance Monitoring Costs

This Excel workbook consists of the following worksheets:

Notes Additional information regarding the query performed to extract pertinant information from the SteamElectric Survey Database.

.
EPA determined maintenance labor and maintenance materials costs for each plant by multiplying plant flow rate by the element-specific cost factors developed as described in this workbook.

Documents the development of element-specific cost factors for cost elements (2) and (3), using certain plant responses to the Steam Electric Survey. To select plant responses used to develop the cost factors, EPA started by extracting operating and maintenance costs for all wastewater treatment systems for plants operating chemical precipitation systems (as marked in B7-4). Next, EPA excluded from the dataset records for those wastewater treatment systems that do not treat FGD wastewater, systems subsequently determined by

EPA to not use chemical precipitation, and plant responses that were too incomplete or otherwise inappropriate for use in this analysis.
