Chapter 1 (Purpose and Need) Betty Peake reported that the Corps has <br />a draft of this chapter and is currently checking on a few things before it <br />will be handed over to Tetra Tech for modification. Tom Browning added <br />that the State and Corps will resolve any issues before it is given to Tetra <br />Tech. He reiterated that he is not intending to keep people in the dark- <br />they are just trying to take care of issues before it goes to Tetra Tech. <br />. Chapter 2 (Alternatives) The Water Users revisions to this chapter were <br />recently received by the Corps, and they are reviewing. They are <br />currently working on some economics issues that Gene Sturm addressed <br />later in the meeting. <br />. Chapter 3 (Affected Environment) A draft of this chapter has been sent <br />to Tetra Tech and updates are in progress. Gary Orendel said that Tetra <br />Tech is adding information on the no action alternative and gravel pits. He <br />is looking for GIS files with the locations of the proposed gravel pits. At <br />this point there are no plans to do field work for the no action alternative- <br />they are just asking agencies for existing information. <br />. Chapter 4 (Environmental Consequences) The sections in this chapter <br />are drafted and will be updated when the contract modification is received. <br />This includes a number of sections (water quality, wildlife, fisheries, <br />vegetation). <br />o Participant question: Will Chapter 4 be sent out separately or will it <br />be included in the draft? Tom Browning replied that there is not a <br />general consensus on when it should come out and that the <br />schedule for the release of Chapter 4 will be decided in the August <br />2151 meeting. Katie Fendel proposed to see the chapter separately <br />before the rest of the draft comes out. <br /> <br />3 <br />
