During the course of a year, the National Park Service (NPS) uses helicopter and fixedwing flights to deliver supplies and equipment to project sites and to perform maintenance of radio towers in the backcountry. Normally the number of flights averages around 50, which the NPS has determined to not cause a measurable effect. Prior to 2003, 33 flights went through the environmental compliance process and received approval to proceed. These include 3 flights for the rehabilitation of the Going to the Sun Road, 20 flights (totaling only 2 12 hours) at Logan Pass to complete the boardwalk rehabilitation project and 4-8 flights to Sperry Chalet to complete the Water Intake Project. During development of this EA the NPS determined that we could reduce the number of already approved flights to 25 by combining the helicopter used for the Logan Pass project with the work at Sperry Chalet. At the beginning of 2003, approximately 112 new flights were proposed in addition to 25 flights that have already been approved. These flights would be used to remove waste from Granite Park Chalet and Patrol Cabin, to rehabilitate the Porcupine Lookout, to perform maintenance on radio towers, and to conduct research and monitoring of threatened and endangered wildlife species and species of concern. The effects of this increase in the number of flights is of concern, thus this Environmental Assessment (EA) has been prepared.
