GENERAL SUBJECT: Vendor cost request for tanks for a che mical precipitation wastewater treatment system.



### TOPICS DISCUSSED AND ACTION TAKEN

On Monday, March 21, 2011 at 4:00 pm I contacted Augusta Fiberglas s to obtain costs for tanks needed for chemical precipitation wastewater treatment systems for FGD wastewater. I was directed to Mr. David Reuis. I explained to Mr. Reuis that we are working on conceptual le vel costing of a chemical precipitation wastewater treatment system to treat FGD (flue gas desulfurization) wastewater from steam electric power plants and as a
part of this project, we are trying to collect cost inform ation on different components or units of a chemical precipitation system. Mr. Reuis indicated that they h ad provided tanks for FGD wastewater treatment before.

I told Mr. Reuis that we would like to get purchase costs including ancillary equipment such as structural
supports and access walkways for multiple tanks. I told him that we had limited information including flow rates and approximate residence times for most of the ta nks, as well as some additional information on the use
of the tank (e.g., lime would be added to reaction tank 1). For some of the tanks, I told him we would like his opinion on the tank needed and the costs. He stated that a s much information as we could provide would be
helpful for him to provide costs, however, they can est imate costs based on the flow rates and residence times

.

I asked Mr. Reuis if there are any power requirements for tanks. He said that if any temperature regulation (i.e., insulation, heating) is needed there may be power requireme nts. I also asked if they could provide costs for
chemical storage tanks. He said they can do this and useful information would be the size of the tank, the chemical stored, the percentage of the chemical and the temperature. He also stated that based on the
wastewater tanks chemical is added to, they can estimate the size of chemical storage tank needed. I also asked Mr. Reuis if they could provide costs for mixers. Mr. Re uis stated that they could provide costs for mixers but
when mixers are provided with the tanks, Augusta Fiberglass obtains them from another vendor and charges a premium on the mixer cost. He stated it is cheaper for a client to go to a mixer vendor directly.

Mr. Reuis asked for the request via email and stated he co uld provide the information within a few days.Project No.: 0172.08.029.044 DISTRIBUTION

### TOPICS DISCUSSED AND ACTION TAKEN

Mr. Michael Hawkins left me a voicemail in response t o my call with Mr. Reuis. On Friday, April 1, 2011 at

10:45 am I contacted Mr. Hawkins to obtain costs for tanks needed for chemical precipitation wastewater
treatment systems for FGD wastewater.

Mr. Hawkins stated that typically shop-built, field-ere cted tanks range from 10,000 gallons to 50,000 gallons in size and would cost approximately $1.25/gallon to purchase. Fie ld-erected tanks range from 50,000 gallons to 250,000 gallons in size and would cost approximately $2.00/gallon to purchase. He said to account for ancillary equipment, such as nozzles and baffles, the cost could be escalated 15%. Mr. Hawkins also stated that the
largest tank (250,000 gallons) would have a diameter of 42 feet and height of 25 feet. The tank size is limited by shipping constraints, such as low overpasses, particularly on the East Coast. Tanks larger than this size would
need to be field-erected and built which would require a bu ild shop on site, increasing the expense.

Mr. Hawkins stated that typically, ancillary equipment provided with the tank includes a mixer bridge, hold down lugs, manways, bolts and gasket for manways, spare no zzles, and level connectors. Ancillary equipment
that may be required but is not included in the purchase c ost includes shut off valves, outlet pumps, and external piping.
