Re: Clarification of Comments on DSEIS Tam: I hope this answers your question; When we started construction of the existing Callaway plant we were planning on 2 SNUPPS units. We excavated the site for two units. Due to economic considerations we cancelled construction of the 2nd unit after the excavation for our 2nd unit was underway. As a result we had an excavation for the Unit 2 which was never built. The excavation existed until recently when we chose to use the excavated area for an ISFSI as well as for a FLEX building in support of Fukushima response strategies. There has been no excavation for a new plant since. While we are considering new plant construction as a long term strategy those plans are conceptual and no firm commitment has been made. Should any new plant ever be built it would be in another location on the site.

Comment no. 3 talks about excavation associated with the construction of the Callaway Unit 1 construction. In the DSEIS, staff talks about new exaction associated with the proposed new reactor at Callaway:

As a result of initiating licensing for Unit 2, Ameren started excavation for the new reactor, and the excavation still exists at the site (Figure 2-4) (Ameren 2011d). Could you please clarify and provide supporting document. Thanks/Tam.

Clarification of Comments on DSEIS Tam, I apologize for missing your call last week, I was out of the office Thursday and Friday. I know you are working on finalizing the draft SEIS and I just wanted to make sure that you are aware of two comments made in our April 7th letter that need some clarification.

Item 6, page 2-18, line 30, 2.1.6.1 - "A statement is made that most of the water in the circulating system is lost to the atmosphere, this is misleading as only about 1% is lost through evaporation."

To clarify, the 1% refers to the total volume of water in the system. However, approximately 75% of the circulating water flow (river water withdrawal) is lost to evaporation and drift from the cooling tower.

Given the context of section I think this comment can be disregarded.

Item 20, H-6, line 15, App H, Suggested resolution - should state "NPDES outfalls 001, 002, 003, 007, and 016 all connect to a single discharge pipeline that discharges to the Missouri River. Outfall 009 has a separate discharge to the Missouri River at the intake. Note that this Outfall has never been used. Storm water runoff outfalls 010, 011, 012, 014, and 015 each flow to separate area creeks."

The original comment contains a typo and should not have listed outfall 009 as connecting to the Missouri River discharge pipeline.

For your convenience I have attached a copy of our comments, as submitted on April 7th. Please feel free to call me if you need any more information or clarifications.
