Requirements To File Notice for Meteorological Towers and Other Wind Energy Systems

Issuing agencies

Abstract

The FAA is proposing to amend requirements applicable to meteorological towers and permanent wind energy systems. This rule would require any person that owns (sponsor) any proposed, altered, or existing meteorological tower to file notice with the Federal Aviation Administration (FAA) if the highest point of the structure is at least 50 feet above ground level (AGL) up to and including 200 feet AGL at its site. The FAA is also proposing marking requirements for meteorological towers constructed or altered after the effective date of a final rule if the highest point of the structure is at least 50 feet AGL up to and including 200 feet AGL at its site. Additionally, the FAA proposes making certain pertinent information about any meteorological tower with the highest point of the structure at least 50 feet AGL up to and including 200 feet AGL at its site available on the FAA's official database. The FAA expects these changes to lower the collision risk for aircraft during low-altitude operations. Moreover, these requirements would partially address two statutory mandates and two National Transportation Safety Board (NTSB) recommendations.
