<br />savings, nor salt saved at the surface, have been estimated. Opportunities exist in the Moab and <br />Rock Springs Districts for plugging additional flowing wells, however, salinity control funds <br />which are annually identified in the BLM budget justification (Washington, D.C. level) generally <br />lose their identity when funds are aggregated at the State Offices. Therefore, well plugging <br />opportunities identified by Field Offices may go unfunded. <br /> <br />~ <br />i-" <br />..... <br />W <br /> <br />In the Monument Butte Oil Field of northeastern Utah, mitigation work has been <br />performed as an offset for surface disturbance and possible diffuse source salt-loading of oil and <br />gas drillpads. Improvements have been made in support of road construction and maintenance. <br />Numerous erosion control structures have been funded by private operators to reduce non-point <br />source loading from saline fields in this field. <br /> <br />Nonpoint Sourcl!lil Salinity Control Activities <br /> <br />Soil, Water, and Air Activity (SWAJ: This program provides for the protection of <br />watershed values and function on the public lands. Its core purposes are to reduce salinity, <br />sediment, and other non-point source pollutant discharge from the public lands in order to protect <br />and enhance water resources. Currently, this program activity provides a salt-load reduction of <br />approximately 10,400 tons. <br /> <br />Watershed improvement practices funded by the SW A activity at the Fort Pearce project <br />in Arizona are creating salt savings. In Colorado's Grand Valley, and on the Grand Mesa slopes, <br />BLM personnel are working with recreation specialists to reduce the impact of off-highway <br />vehicles (ORY) on Mancos shale-derived soils and on steep dissected slopes. The White River <br />Resource Area is implementing salinity controls on the Baking Powder portion of the Lower Wolf <br />Creek project. Also in the White River Basin, controls were started in 1993 and continue in the <br />Evacuation Creek drainage. At White Face Butte, numerous small watershed control structures <br />have been constructed. The Dry Creek Basin Coordinated Range Management Plan (RMP) is <br />being implemented in part with funds from a Section 319 Clean Water Act grant to the San Miguel <br />Soil and Water Conservation District. <br /> <br />In the Little Colorado River drainage, salt savings have been achieved on 5,073 acres with <br />the installation of sediment traps. On BLM roads and rights-of-ways in New Mexico, <br />maintenance and corrective measures have been taken to minimize sediment transport from saline <br />soils. Sediment detention reservoirs (Sager's Wash) and sagebrush roller chopping (Nash Wash) <br />have created salt savings, as has the trapping of suspended sediment by the Parlette wetlands. In <br />Utah, the Richfield District has stabilized saline sediments with channel structures and reseeding <br />at Meadow Gulch, creating significant salt savings; <br /> <br />The Round Valley, Utah, project would remove 350 tons/year of salt from Colorado River <br />tributaries. Preliminary engineering studies have been conducted on a potential site for a large <br />sediment control structure, but funds are lacking. The Birch Creek, Blind Trail, Factory Butte, <br />and Last Chance areas in the Richfield District have been assessed for potential salinity control <br />projects. <br /> <br />4-8 <br />
