Show oppose pumped- back storage reservoir development on Lake Powell ( because of potentially significant impacts and limited public benefits), this issue is not considered a current problem requiring planning. " Acid rain," or acid deposition, is another issue that initially was considered. However, acid deposition is not at present considered a problem in the arid Southwest deserts because of predominantly calcareous soils and basic waters with a high buffering capacity. Regional programs already in place to monitor acid deposition will provide adequate early warning of any change in conditions that could lead to an adverse effect in the Glen Canyon area. Therefore, advance planning relating to acid deposition is not deemed necessary at this time. The third of these potential problems relates to lakeshore development. Glen Canyon National Recreation Area is a developing park for which plans have been proposed for two new marinas and expansion plans approved for several existing marinas and water- related facilities. More specifically, these planned developments include the following: • Halls Crossing Amended Development Concept Plan ( DCP) ( September, 1985): Provides for increased recreational use at Halls Crossing through expansion and/ or addition of water- related facilities, including public boat launch ramp, boat pump- out facilities, marina expansion, water supply well, and sewage lagoon and aeration system. • Lone Rock DCP ( August, 1981): Provides for beach camping and day- use areas, boat launching area, potable water supply, and sewage treatment. • Bullfrog Basin Amended DCP ( September, 1985): Provides for the modification and/ or addition of various water- oriented facilities, including public boat launch ramp, marina, and floating sanitary dump station. • Wahweap DCP ( July, 1983): Provides for potable water well modification; construction of additional water tank; and additional sewage lagoons, boat launch ramps, and marina facilities. • Hite Developed Area DCP ( August, 1983): Provides for expansion of the potable water supply and treatment systems and modification of the sewage disposal system. • Lees Ferry DCP ( August, 1985): Provides for improved river launching facilities and relocation of water treatment facilities, as well as reopening an irrigated ranch as a living- history interpretive exhibit. • Paiute Farms/ San Juan Marina DCP ( September, 1985): Draft plan calls for development of an interim facility at Paiute Farms 64 |
