## Steam Electric Questionnaire Part C. Instructions



# "Fly ash collection" is the separation of fly ash from the flue gas. Examples of fly ash collection equipment include ESPs and baghouses. Fly ash may also be collected by wet scrubbers. **"Fly ash conveyance"** is the conveyance of fly ash from the fly ash collection equipment (ESP or baghouse) of one or more generating units to intermediate or final storage (e.g., storage silos or ponds/impoundments). Common dry fly ash conveyance components include filter/separators, vacuum/pressure transfer stations, high pressure blowers, and associated high pressure piping (note that conveyance does NOT include the storage/loading silos). W et fly ash conveyance equipment is used to sluice fly ash and pump it to wet ash storage (e.g., ash ponds/impoundments). **"Bottom ash conveyance"** is the conveyance of bottom ash from the boiler(s) of one or more generating units to the intermediate or final storage of the bottom ash. Dry bottom ash conveyance does not use water to convey bottom ash to intermediate/final storage. Dry bottom ash conveyance includes systems that collect and convey the bottom ash without any use of water, as well as systems in which bottom ash is conveyed mechanically or pneumatically away from a quench water bath (e.g., submerged chain conveyor systems). W et bottom ash conveyance uses water (i.e., a sluice) to convey bottom ash away from the boiler to intermediate/final storage (e.g., ponds/impoundments). Note that dewatering bins are considered part of bottom ash conveyance. **"Intermediate storage"** refers to a facility or site where collected fly ash or bottom ash is stored after conveyance and prior to being transported to final disposal. Dry fly ash intermediate storage typically consists of storage silos. Dry bottom ash intermediate storage typically consists of stackout piles for the bottom ash collected from mechanical drag systems. W et fly ash or bottom ash intermediate storage typically consists of ponds/impoundments. **"Ash transport/disposal"** refers to the transportation of ash from intermediate storage to final disposal. Examples of ash transport/disposal include transportation used to haul ash off site (e.g., ash that is marketed and shipped off site to a reuse application). Ash transport typically consists of roads and vehicles that are used to transport the ash.

**Note: If any components of the conveyance portion of the fly ash handling system are shared w ith one or more other generating units, only report those components and**  **corresponding costs once.** The conveyance portion of the fly ash handling system refers to the part of the system that conveys fly ash from the fly ash collection equipment (ESP or baghouse) of the generating unit to intermediate or final storage (e.g., storage silos or ponds/impoundments). Common dry fly ash conveyance components include filter/separators, vacuum/pressure transfer stations, blowers, and associated high pressure piping (note that conveyance does NOT include storage or loading silos nor does it include movement between intermediate and final storage). Common wet fly ash conveyance components include sluicing equipment, associated piping, and pumps (note that conveyance does NOT include ponds/impoundments).

Identify the major components of the conveyance portion of the fly ash handling system, in particular those components that represent a significantportion of the capital or O&M costs for the system. Provide the type of component and the number of each type of component in the system. Additionally, provide the total system capacity of each type of unit component (i.e., volume of clarifying tanks). Total system capacity should equal the sum of the capacity of each individual component within that type. **Type of Component** Yes

Dry bottom ash handling includes systems that collect and convey the bottom ash without any use of water, as well as systems in which bottom ash is conveyed mechanically or pneumatically away from a quench water bath (e.g., submerged chain conveyor systems). W et bottom ash conveyance uses water (i.e., a sluice) to convey bottom ash away from the boiler to intermediate/final storage (e.g., ponds/impoundments).

Is this storage destination a pond/impoundment? Does this storage component store both fly and bottom ash together? For example, if bottom ash and fly ash are conveyed separately but stored in a common silo, the silo is considered a shared component. If you are instructed to skip forward to another section while completing this section for one bottom ash storage destination, be sure to complete this section for all other bottom ash storage destinations operated in 2009, being installed, or planned to be installed by December 31, 2020. The intermediate storage of bottom ash handling refers to the facility/site where collected bottom ash is stored after conveyance, prior to the ash being transported to final disposal. Dry bottom ash intermediate storage typically consists of storage silos. W et bottom ash intermediate storage typically consists of ponds/impoundments. Note that intermediate storage includes all equipment and operations associated with loading dry or moisture-conditioned ash into trucks or rail cars for transport. Intermediate storage also includes all ash dust suppression activities at the plant.

The transport/disposal portion of the bottom ash handling system refers to the transportation of bottom ash from intermediate storage to final disposal. An example of ash transport/disposal is transportation used to haul ash off site (e.g., ash that is marketed and shipped off site to a reuse application). Ash transport typically consists of roads and vehicles that are used to transport the ash. The capital and O&M costs for ash transport/disposal may include the road or rail infrastructure (roads, tracks, lights), the trucks and rail cars, the operation and maintenance costs associated with the trucks and rail cars, and ash disposal fees. Note that capital and operation and maintenance costs associated with ponds/impoundments and landfills/landfilling are requested in Parts D and F, respectively, and they should not be provided here in Section 3.5.
