PART C. ASH HANDLING

Use the Part C Comments tab to do the following: provide additional information as 

requested in certain questions within Part C; indicate atypical data (e.g., if 2009 

information is not representative of normal operations); and note methods used to make 

best engineering estimates in the event that exact data are not available.

INSTRUCTIONS

Part C requests information about ash handling operations at your plant. Complete Part 

C if ash is generated in any fossil-fueled steam electric generating units at your plant. 

See Part A Section 8 for steam electric generating unit fuel classifications.

As you are completing the electronic form, note the following: When you enter your plant 

name and plant ID on the Part C TOC tab, all name and ID fields throughout Part C will 

automatically populate. Refer to the overall questionnaire instructions, the glossary, and 

the acronym list for assistance with completing Part C. 

Please provide all free response answers in the highlighted yellow areas. Throughout 

Part C, you may need to make copies of certain sections/questions. Instructions are 

provided throughout Part C regarding making copies. Note that Steam Electric Unit IDs 

or Storage IDs must be populated on the copied tab or section, located in the upper right 

corner under "Plant ID" and "Plant Name", in order to correlate the requested 

information with the steam electric unit or ash handling system.

Where the questionnaire indicates to provide an attachment, an electronic format (e.g., 

PDF) is preferred; however, hardcopies are also acceptable.

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.
