These procedures are for complaints of discrimination, other than employment discrimination, by the Long Island MacArthur Airport. They apply to discrimination by airport employees, contractors, concessionaires, lessees, or tenants of the Long Island MacArthur Airport facilities based upon race, creed, color, national origin, or sex, including but not necessarily limited to complaints under Title VI of the Civil Rights Act of 1964 and the Civil rights Restoration Act of 1987. They cover any program or activity administered by the Long Island MacArthur Airport. Any person who feels that he or she has been subjected to discrimination on the basis of race, creed, color, national origin, or sex has the right to file a complaint with the Airport. These procedures do not deny or limit the right of a complainant to file a formal complaint with an outside agency, such as the U.S. Department of Transportation or Federal Aviation Administration (FAA), or to seek private legal counsel regarding discrimination.

State Superfund Site Classification at ISP

The New York State Department of Environmental Conservation (NYSDEC) State Superfund Site Classification Notice dated February 2023 designated areas of MacArthur Airport as an Inactive Hazardous Waste Disposal Site. This designation stems from the classification of chemical compounds Perfluoroalkyl and Polyfluoroalkyl (PFAS) and Perfluorooctanoic Acid (PFOA) as hazardous substances under New York law. In 2016, the Federal Health Advisory (HAL) Drinking Water Guidance Levels were reduced to 70 Parts Per Trillion (PPT) for PFOS and PFOA and since that time, New York has enacted drinking water standards of 10 ppt for both chemicals.
