Show Visual and esthetic environments as related to recreational, residential, and travel purposes. QUALITY OF EXPERIENCE igh capacity for direct and detailed sensory involvement. Natural dominance of form, scale, and proportion. High constraint, vividness, image creation, and unity. Avoid disturbance of natural pattern. Prohibit intrusions of logging, mining, intensive recreation, roads, power lines, etc., except insofar as environmental design studies indicate that intentional display of resource management is consistent with scenic management objectives. E-2 Cultural, historical, and informational values for recreational and educational purposes. E-3 Personal and social experiences free from crowding, development, and noise. E-4 Natural biological and physical features. Unique, archetypal, rare, or transitory artifacts or locations relative to the environmental context. High capacity for isolation and interaction with national environment. Minimum intrusion of man-made structures and facilities and man-induced changes. Low artificial noise levels (vehicles, aircraft, radios). Unique or dramatic landforms or features (not necessarily of biological importance). High capacity for orientation (as with landmarks). Rare or especially archetypal geologic formations. Preservation or restoration. Prohibit competing land uses. Protect from overuse by recreationists and collectors. Limit number of recreation visitors through rationing of physical design. Prohibit or minimize noise producing intrusions. Prohibit development of structures except where design studies show minimum disturbance. Modify resource management practices to enhance such features. Prohibit or restrict extractive or product-oriented uses except as they may be shown to complement feature-oriented uses. AIR QUALITY A-l Human health protection (respiration; sight; skin). A-2 Natural biosystem protection (carbon dioxide-oxygen exchange balance; foliage burn). A-3 Materials protection (corrosion; etching; stain). A-4 Esthetics protection (haze; odors). Hold levels and combinations of oxides of sulfur and carbon, hydrocarbons, photochemical oxi-dents, and particle (solid) matter to tolerances required to support each purpose of air quality maintenance on both a 24 hour and annual basis. Maintain natural background levels of particle matter in ambient air in rural areas to the extent possible. Specific conditions to be maintained depend on different meteorological conditions, climate (wet, dry) topography, and latitude-longitude. Control use of internal combustion engines on public land areas to hold hydrocarbon and particle matter below necessary levels. Control dust generated by mining and logging, and by recreational vehicles and logging and ore trucks traveling on unpaved land. Control stack emissions from on and offsite pulp and paper mills, concentrate mills, organic fueled power generating plants, and other industrial plants to hold particle matter and gaseous pollutants to necessary levels. Burning of logging waste and controlled burning of forest and rangelands for management purposes to be regulated daily and seasonally to meet necessary air quality requirements. E-l |
