000182 VIlI. PROGRAM SCHEDULES AND COSTS A. Activity Schedule Activities required to accomplish the CREST Program are divided into several categories: Demonstration Program, Transferability Studies, Extra-Area Effects Studies, Environmental/Social Studies, and Evaluation. The overall CREST Program schedule is presented in figure 6, which shows major activities as scheduled by project year. During the first 3 years of CREST, equipment required for all aspects of the program will be procured, delivered, tested, and installed. Some of the equipment is readily available from suppliers, while others must be designed and built. Off-the-shelf equipment can generally be delivered in less than 1 year. Much of the equipment required for CREST is not avai 1- able off the shelf, and will require up to 2 years to build, test, and deliver. In addition, since the program is conducted in high.mountainous terrain, equipment can only be installed during a limited period of the year, specifically June through September. Because of these two factors it will take up to 3 years to get all required equipment in place. The primary CREST activity is the conduct of the demonstration program at two field sites within the Basin. The initial activity at each site will be to select and establish the field sites and begin installing and testing equipment. After sufficient equipment is in place randomized seeding operations will be initiated to serve as the basis for quantifying the results of the program. Seeding will begin at the earliest possible date after the start of CREST. This is projected to be at the start of the third year because of the time required for equipment, procurement, development, and installation and approval to instrumeni wilderness areas. The randomized seeding program will last 6 years at each demonstration site. The minimum time required from program start to first seeding is 18 months; but, because operations can be conducted only in the winter months (November to April) 2 full years are required. It should be noted, however, that design adaptation studies will be conducted earlier. Transferability studies will consist of 2 years of intensive physical measurements made at each of the six subbasin areas. These studies wi I I be conducted at two basins annually, starting with the demonstration sites. In parallel, limited background measurements will be made annually in all subbasins. Environmental/social monitoring and public involvement activities will occur each year. A field monitoring program will be established to measure the effects of varying amounts of snowfall and snowpack upon the physical environment. Open communications with the citizens will be maintained throughout the project. An ongoing evaluation effort will be conducted to determine the progress of the program annually. It will address the technical, environmental, and economic aspects of the program. This evaluation will allow for continuous feedback of new information into the program. In addition, it will make available the current status of the program so that prior to its 41
