Jeff,

I can’t seem to be able to pick out the shaded area that indicates the SPS water rights in Attachment
1. Would it be possible to get another copy of this map with the area outlined in yellow, while retaining the locations of the wells and pipelines?

Jeff,

Can you provide a map that indicates the locations of the water wells described in your response? Do you have a table or spreadsheet that indicates the withdrawal rate of these wells? Also, pls go to
this link:

http://interchange.puc.state.tx.us/WebApp/Interchange/Documents/43695_194_837256.PDF

See p. 21:

“QUESTION NO. AXM 12-13: [Decommissioning] - Please identify the quantity of water rights directly owned or where the Company has a financial right to resale or lease water rights for some period of time in the future at each of the Company's power plants. For each water right where the Company has ownership or financial interest in water rights, provide the current expected market value for each such water right and the basis for such estimation.”

Note the table provided indicates that Tolk/Plant X has access to an estimated greater than 140,000
acre-feet of recoverable water.

How does this figure align with the information you provided? Where is this water located and is any of it outside of the approximately 47,000 acre area discussed earlier? Is any of this water being
sold?

Thanks.
