Thanks Jeff. I’m still not clear about my last two questions: 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?

Specifically, your letter mentions the acquisition of an additional 3,100 acres on the east side of the
well field. Does this acreage include all of the Barrett and Rose acquisitions mentioned in the attached testimony? Can you supply a map that outlines all of the water rights acreage, as it appears the map I received from the HPWCD is outdated?

Is any of this water being sold for use by entities other than Plant X or Tolk?

Thanks.

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.
