This legislation, titled the Sloan Canyon Conservation and Lateral Pipeline Act , amends the Sloan Canyon National Conservation Area Act to modify the conservation area's boundaries. Specifically, it updates the official map and expands the acreage from 48,438 to 57,728 acres. The bill also ensures that the expansion respects and preserves existing utility transmission corridors and rights-of-way, allowing for continued operation, maintenance, and even the establishment of new facilities within these designated areas. A key provision of the bill requires the Secretary of the Interior to grant a right-of-way to the Southern Nevada Water Authority for the Horizon Lateral Pipeline within one year. This right-of-way, granted without payment of rents, covers temporary and permanent water pipeline infrastructure, powerlines, facilities, and access roads for geotechnical investigations and construction. The Authority is permitted to excavate and dispose of tunneling materials, provided it enters into a memorandum of understanding with the Secretary for disposal locations, and the right-of-way must protect conservation resources and avoid wilderness areas.
