On October 23, 2013, FAA published its Interim Policy, FAA Review of Solar Energy System Projects on Federally Obligated Airports (the Interim Policy).  The Interim Policy clarifies and adds standards for the measurement of both “glint” and “glare” as presented in FAA’s Technical Guidance for Evaluating Selected Solar Technologies on Airports (the Technical Guidance), originally published in 2010.  Specifically, the Interim Policy clarifies an airport sponsor’s obligation to file FAA Form 7460-1 for all proposed on-airport solar installations, provides standards for ocular impact of solar installations, and identifies a computer-based tool for assessing ocular impact.  FAA intends to finalize the Interim Policy and include the standards for ocular impact in an update to the Technical Guidance that will be published later this year.
