CHANGE Environmental, LLC assessed a potential air quality impact of operations at East Hampton Airport (International Air Transport Association airport code: HTO). HTO is a public use, general aviation airport located just west of the town East Hampton, in Suffolk County, New York. The airport is owned and operated by the Town of East Hampton. The purpose of the assessment was to evaluate whether the airport’s aircraft operations significantly impact local air quality such that additional emissions control measures or air quality studies should be considered. For this assessment, CHANGE evaluated emissions from the following aircraft operations at the airport: aircraft engines, auxiliary power units and ground support equipment. Other emissions sources at the airport, to the extent they exist, are not expected to significantly contribute to the airport’s emissions inventory. For the local air quality, consistent with the 2017 National Emissions Inventory (2017 NEI), CHANGE evaluated emissions from on-road vehicles traveling on major local roadways as a surrogate for air quality impacts from the most significant emission sources in East Hampton area.
