Hi Dennis, 

 

Thank you for the information you provided on concrete silos for EPA's Steam Electric ELG 

back in October 2011. As we are getting ready to finalize the docket supporting this effort, I 

would like to request your permission to use the e-mails below as part of the documentation for 

the Steam Electric ELG, made available at regulations.gov. When there is an e-mail 

signature/footer that claims information as confidential, EPA cannot include it a part of the 

public docket and handles it as CBI. If you approve, we will simply remove the following footer 

from the e-mail correspondence and include this information in the public docket.

Elizabeth, 

Here is a selection of larger silos for fly as the previously sent to you. 

Foundations vary greatly with the silo depending on the local soil conditions. It can be 10% to 50 

% of the silo cost. It just depends on the soil conditions, is it a rock foundation where you just 

need to pour a small mat type foundation or is it on bad soil and you need lots of 100 ft. long 

piles with a pile cap. 

Diameter Height Volume Tons Total 

50 150 294,525 4,170 $ 2,724,356.25 

56 165 406,397 5,950 $ 3,759,175.73 

65 195 647,071 10,000 $ 5,920,703.54 

70 210 808,177 12,800 $ 8,041,357.17 

Let us know if we can help further.

Subject: RE: Silos Costs - Concrete 

 Dennis, 

 Thank you for the information provided. This is a great help. I have two follow up questions for 

you regarding the data below. 

 
1. Do you have an idea of the largest typical concrete silo that would be constructed (in tons of 

fly ash for 3 days), before downsizing to multiple smaller concrete silos for handling the ash. It is 

greater than the largest size (46' X 132' 2,904 Tons Capacity) listed in your file. If so, could you 

provide the cost and size for such a silo. 

2. You mentioned that the costs included do not include costs for foundations. Do you have any 

idea the typical cost or material of construction for foundations (capital and O&M). 

 

Please let me know if would be easier to address these topics over the phone, my phone number 

is 703-633-1659. 

 

Thank you in advance, 

Elizabeth

Subject: Silos Costs – Concrete 

Dennis, 

Thank you for your time on the phone earlier today. As discussed, EPA is collecting cost data on 

concrete silos to support the Steam Electric Effluent Guidelines Rulemaking. This data will be 

used to estimate the capital and operating and maintenance (O&M) costs associated with 

converting fly ash handling systems from wet to dry. 

 

Specifically, EPA/ERG would like to request capital and O&M (if applicable) for concrete silos 

that correspond the ash tonnages in the attached Excel spreadsheet. 

 

For the costs provided, please also provide a list the materials included in the cost. For example, 

does the capital cost include only the cost of the concrete and installation of the silo or are there 

other pieces of equipment that are installed along with the silo. In addition, could you please 

provide a methodology for estimating silo height and diameter based on ash tonnage? 

 

Thank you again for your time and consideration. 

 

Elizabeth
