The <br />annual salt load reduction at the end of the reporting period is <br />11,000 tons. About 31 percent of the contracts prepared include <br />both upland and wetland habitat practices. <br /> <br />Moapa Vallev Unit - Preparation of the Moapa Valley draft <br />environmental impact statement (ElS) continues. Public scoping <br />meetings have been held in the area and the draft EIS is being <br />prepared. The final EIS is scheduled for publication in 1992. <br /> <br />Cooperative Extension Service-Information and Education - The <br />Cooperative Extension Service is responsible for development and <br />coordination of the USDA information and education programs for the <br />salinity control program. Full time extension agents are located <br />in the Grand Valley, uinta Basin, Big Sandy River, Lower Gunnison <br />and McElmo Creek areas. Part-time assistance is provided in the <br />Moapa Valley area. <br /> <br />. <br /> <br />Monitorinq and Evaluation Monitoring and evaluation <br />activities continue to be conducted in each of the USDA salinity <br />projects. Their primary purpose is to monitor the effects of the <br />USDA salinity control program on salt load reduction. Also being <br />assessed are the project's effects on wildlife habitat. Annual <br />reports are prepared to provide information on the monitoring and <br />evaluation activities. USDA has undertaken efforts to improve the <br />uniformity of these reports throughout the Basin. Interim <br />instructions to be used as a guide for all monitoring and <br />evaluation activities associated with the Colorado River Salinity <br />Control program were released in August 1991. <br /> <br />Research - The U. S. Salinity Laboratory has developed and <br />successfully field tested mobilized/automated systems for <br />measuring, inventorying, and monitoring soil salinity in irrigated <br />soils. The technology can be used to inventory and monitor soil <br />salinity to assess the adequacy of leaching, drainage, irrigation <br />uniformity, determining sources of salt loading and for evaluating <br />salinity reduction practices. Also the U.S. Salinity Laboratory <br />has made conceptual/modeling studies to evaluate various irrigation <br />/ drainage strategies to reduce water pollution. This research <br />shows that intercepting, isolating and reusing drainage waters for <br />irrigation will maximize the usability of the total water supply <br />and minimize drainage disposal and water pollution problems, <br />including brochures, newsletters, field days, field testing, and <br />demonstration of irrigation equipment. <br /> <br />Environmental Protection Aqency <br /> <br />. <br /> <br />The Regional Administrator from EPA Region VIII led a <br />discussion on areas of concern to both EPA and the Colorado River <br />Basin Salinity Control Forum at the Octobe(1990 Forum meeting. <br />~ <br />EPA continues to maintain its involvement in the environmental <br />impact statement (EIS) process for the following salinity control <br />units: Price-San Rafael Rivers, Moapa Valley, San Juan River Basin <br /> <br />12 <br />
