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). Wet 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). Wet 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. Wet 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.

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 significant portion 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

Is a pond/impoundment unit or pond/impoundment system the final destination of all fly ash collected by the plant?

Does the plant use the same transport and disposal equipment for both fly and bottom ash? For example, if fly ash and bottom ash are transported using the same trucks, the trucks are considered a shared component.

The transport/disposal portion of the fly ash handling system refers to the transportation of fly 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: If any components of the conveyance portion of the bottom ash handling system are shared with one or more other generating units, only report those components and corresponding 

costs once.

The conveyance portion of the bottom ash handling system refers to the part of the system that conveys bottom ash from the boiler(s) of the unit to the intermediate or final storage of the 

bottom ash. 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). Wet 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.

Note: Bottom ash conveyance includes all capital and O&M costs required to dredge or empty ponds, dewatering bins, and/or surge tanks to intermediate 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. Wet 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.

planned to be installed by December 31, 2020. 

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.

Does the plant use the same transport and disposal methods for both fly and bottom ash? For example, if fly ash and bottom ash are transported using the same trucks, the trucks are considered a shared component.

Is a pond/impoundment unit or pond/impoundment system the final destination of all bottom ash collected by the plant?
