GENERAL SUBJECT : Potential Changes to the Ash Handling Part of the Steam Electric ICR 

TOPICS DISCUSSED AND ACTION TAKEN

Sarah Holman and I contacted Craig Fleming, Delta Ducon, on Thursday, January 28, to discuss the potential 

changes that EPA was considering making to Part C (Ash Handling) of the questionnaire. We briefly talked 

with Mr. Fleming regarding his thoughts about these potential changes. Below is a summary of the call.

Mr. Fleming agreed that asking for ash handling information on a system level is a good way to go; however, he

wanted to make sure that we allow for plants that have multiple generating units and have dedicated ash 

handling systems for each generating unit (like Fayette). We explained that our current setup will allow for this 

type of response.

Mr. Fleming stated that it makes sense to ask for costs in three categories (conveyance, intermediate storage, 

and transport/disposal), and that he thinks that plants that installed ash handling systems after 1980 should have 

costs broken out in such categories. He stated that before 1980 they more likely would have purchased the 

system as one lump sum, which would make it difficult for them to split up costs in these three categories.

Therefore, he agreed with splitting up the costs, and our suggested timeframe for gathering the costs on ash 

handling systems.

Mr. Fleming stated that he does not know of any plant in the US that is combining fly and bottom ash in a silo.

He stated that Crystal River is the only plant that he knows of that is even handling bottom ash completely dry

(using a Magaldi system) in order for that to be possible. Mr. Fleming explained that plants in China 

collect/handle their bottom ash dry and then mill it so that they can sell it with fly ash.

Mr. Fleming stated that he believes the vast majority of plants would have the vertical space required to retrofit 

a boiler with a dry bottom ash handling system. The DRYCON system needs about 10 ft of vertical space 

below the boiler and most boiler hoppers are about 16 to 18 ft in height. He explained that Magaldi's dry

bottom ash equipment is taller, and so, there may be some vertical space issues that have been encountered 

overseas. Mr. Fleming discussed the space issues that may be encountered in US plants with conveying the 

bottom ash from the boiler out of the building. He suggested we ask the plants if they have space available for 

bottom ash to exit the building in a "straight shot". If not, capital costs could increase greatly (he cited one 

example where multiple DRYCONs had to be installed off-center from the boilers and then those fed another 

DRYCON that conveyed the bottom ash outdoors).

Mr. Fleming also informed us that he reviewed the questionnaire and thinks it's good and detailed. He is 

concerned that we are classifying a submerged chain conveyor as a dry bottom ash handling system because it 

still uses water. We stated that we think we have the submerged chain conveyor system appropriately

categorized for the purpose of the data collection.

Mr. Fleming stated that they do have some cost comparison info that could help us, previously talked about in 

the UCC conference call on December 17, 2009, and said he would send it our way soon.
