Subject: RE: Draft Iatan Site Visit Notes

Thomas - The following are responses to comments and edits to your notes. There is no CBI material in the note narrative. Note attachments 2 

and 3 are CBI drawings.

Page 1:

Iatan receives its coal via train. The plant burns approximately 11,000 tons of coal per day. Iatan stores 70 to 75 days worth of coal on site for 

Unit 1 and approximately 30 days worth of coal for Unit 2. The coal pile runoff is collected in a holding pond and then discharged to the Missouri 

River.

The dry fly ash and PAC material is pneumatically conveyed from the baghouse hoppers to the fly ash silo for each unit. The plant has the 

capability to unload the fly ash wet or dry. For wet unloading, the fly ash is conditioned with either service water or the FGD brine from the 

treatment system for dust control. This fly ash material is transferred to the onsite landfill for disposal. The plant can also unload the fly ash 

dry for beneficial reuse.

Page 3:

The underflow from the thickener is mixed with a polymer and dewatered using a belt filter press. The solid waste is trucked to the onsite landfill 

for disposal. The overflow from the thickener is transferred to the raw water clarifier.

Page 5:

Iatan operates an onsite landfill, which began operation in January 2009. The landfill has four stages and the plant is currently filling Stage 1. 

The landfill has a two foot clay liner, 60 mm HDPE liner, and 12 inches of sand.

The plant collects landfill leachate and runoff in separate collection ponds. The leachate is used for dust suppression control on the landfill. The 

plant has an emergency discharge outfall from the leachate collection pond.

Iatan has eight groundwater monitoring wells around the landfill. All of the wells are considered by MDNR to be downgradient

Subject: Draft Iatan Site Visit Notes

Paul/Tom,

Representatives of the Environmental Protection Agency (EPA) and Eastern Research Group (contractor to EPA) visited Kansas City Power & 

Light's Iatan Generation Station on April 28, 2010 to gather information for the Agency's rulemaking and identify potential sampling points for 

its sampling program. The draft site visit notes and associated attachments summarizing the processes observed and the information collected 

during the site visit are being shipped to Tom (i.e., the plant) via FedEx for delivery Wednesday morning. Please review these documents 

paying particular attention to accuracy and any potential confidential business information (CBI) concerns. During the site visit, some of the 

information was flagged as potential CBI; therefore, when reviewing the notes, please identify the specific CBI, if any, contained within the 

notes.

Please note that there are a few outstanding questions contained within the notes. Specific questions are embedded and highlighted in the text of 

the draft site visit notes. Following receipt of your comments, EPA will finalize the notes for inclusion in the record associated with the proposed 

revisions to the steam electric effluent guidelines.

EPA requests that you provide comments on the draft site visit notes by January 11, 2013. If comments are not received by this date, EPA will 

assume that the notes are accurate and that there are no CBI concerns regarding the information included in the notes. You may send your 

comments to Jezebele Alicea via e-mail (if not CBI) at alicea.jezebele@epa.gov<mailto:alicea.jezebele@epa.gov>, or by mail to:
