This proposed rule would codify a nondiscretionary provision of the Ski Area Recreational Opportunity Enhancement Act of 2011 (Pub. L. 112-46). The proposed rule would amend the definition of a ski area at 36 CFR 251.51 to note that other natural resource-based, seasonal, and year-round recreational uses and facilities may be authorized, provided that the primary purpose of the site remains skiing and other snow sports. It would bring regulations into compliance with statute and reduce regulatory burden on the ski industry, in accordance with Executive Order 14192, Ensuring Lawful Governance and Implementing the President's "Department of Government Efficiency” Deregulatory Initiative.
