The Big Sandy River contributes an estimated average of <br /> <br />164,000 tons of salt each year to the river. The salt is dissolved from <br /> <br />saline bedrock and carried to the Big Sandy River by deep percolating <br /> <br />irrigation water. <br /> <br />PLAN <br /> <br />The recommended plan of development for the Big Sandy River Unit would <br /> <br />reduce salt loading to the Big Sandy, Green, and Colorado Rivers and <br /> <br />would develop 12,000 acre-feet of water from the Big Sandy River for <br /> <br />industrial use by Chevron Chemical Company and Texasgulf Chemicals, <br /> <br />Incorporated. A well field would be installed as part of the unit along <br /> <br />the Big Bend area near the Big Sandy River. Saline water collected at <br /> <br />S-l <br />
