The United States National Transportation Safety Board has issued safety recommendation A-13-020, identified under reference number WPR11LA094. This directive is addressed to the United States Department of the Interior, the United States Department of Agriculture, and the United States Department of Defense. The board urges these federal agencies to take specific action during their organizational review and approval processes for applications to construct meteorological evaluation towers. Specifically, the recommendation requires that these departments provide a copy of Advisory Circular 70/7460-1, titled Obstruction Marking and Lighting, directly to applicants. Alternatively, the agencies may direct applicants to this advisory circular as part of their standard procedures. This measure aims to ensure that all relevant parties are aware of the established standards for marking and lighting these structures.
