The Trona Refinery in Sweetwater County, Wyomin~ by Henry Harris, FMC Corporation Westvoco, WYoming . I understand that you gentlemen are responsible, or, at least, the agencies which you represent, are responsible for the management of 600 billion gallona a day of fresh water in the United States; i.e., your portion of the Pacific Southwest. Six hundred billion gallona a day seems like a lot of water. I don't know what our share is out here, I suppose that is significant. It is probably adequate for the needs'if well managed, but it is less than three percent of the world's water. I'm bringing coals to new castle; I think I see it in your thinking. But this is information that I only became aware of after I began work with the 208 Committee in Wyoming. We became very interested in what is our share of water?, how it is used, and what are the priorities? So I am repeating a little bit of what I was exposed to. How we use our three percent in the United States is going to be very important in the future. I think that we in our industry are using it effectively, but we must be more efficient in how we use it. An article that I read recently reported on the high uae of water in the production of some of the things that are essential to our way of life; e.g., the production of steel requires 30,000 gal- lona of water to produce a ton of steel and to produce a ton of paper requires 150,000 gallons of freah water. I suppose the moral of thia story is that only a gallon of water ia required to produce a pint of beer. Now, if you want to set your priorities, then, I guess that is the way to do it. In our business, we do have constraints, but we wind up using about 575 gallons of water per ton. Of course, we are aiming for the lowest per unit use. Because of governmental regulationa, at the present time, there is no water recycle. That leads me to the sub- ject of the present benevolence of nature. In southwestern Wyoming, we don't have the plethora of trees that exist in the Northwest Region, but we do have minerals. The most unique mineral deposit in the world, Trona, exists in Sweet- water County, I mean that literally, it is unique. We, and many other companies, have searched over this whole world for something that is similar. The mineral itself is not highly valuable in dollars per ton, but it is essential to our way of life. The mineral ia used in many ways. There are only two other areas, really, where such a chemical is derived, one ia from a lake in Kenya, Africa and the other is from a lake in California. Most of those are relatively insignificant as for the sources of this mineral. The reason we are blessed in Wyoming, is that we have probable reserves that are economic, not only at the present time, but will be economical C-12
