Aspen provided consulting expertise in planning the regulatory compliance and permit acquisition for Caltech's proposed installation of a radio telescope array at a high elevation site in the USDA Forest Service's Inyo National Forest. This included preparation of the Special-Use Permit application materials. Aspen previously assisted in the planning for other permits, public involvement, wildlife resource inventories, and plans for the EIS and EIR processes, with the Inyo National Forest and the University of California as the Federal and State lead agencies, respectively.
