Abstract

EPA is taking direct final action to exempt the three U.S. Pacific Island Territories--American Samoa, Guam, and the Commonwealth of the Northern Mariana Islands (C.N.M.I.)--from the gasoline sulfur requirements that EPA promulgated in the Tier 2 motor vehicle rule. The Governor of American Samoa petitioned us for an exemption from the Tier 2 gasoline sulfur requirement because of the potential for gasoline shortages, the added cost, and the minimal air quality benefits the Tier 2 gasoline sulfur requirement would provide to American Samoa. Representatives of the Governors of Guam and C.N.M.I. have also requested an exemption referencing the petition submitted by American Samoa. Generally, the Far East market, primarily Singapore, supplies gasoline to the U.S. Pacific Island Territories. The Tier 2 sulfur standard effectively requires special gasoline shipments, which would increase the cost and could jeopardize the security of the gasoline supply to the Pacific Island Territories. The air quality in American Samoa, Guam, and C.N.M.I. is generally pristine, due to the wet climate, strong prevailing winds, and considerable distance from any pollution sources. We recognize that exempting the U.S. Pacific Island Territories from the gasoline sulfur standard will result in smaller emission reductions. However, Tier 2 vehicles using higher sulfur gasoline still emit 30% less hydrocarbons and 60% less NOX than Tier 1 vehicles and negative effects on the catalytic converter due to the higher sulfur levels are, in many cases, reversible. Additionally, these reduced benefits are acceptable due to the pristine air quality, the fact that gasoline quality will not change, and the cost and difficulty of consistently acquiring Tier 2 compliant gasoline. The Tier 2 motor vehicle rule also sets standards for vehicle emissions. Vehicles in use on the U.S. Pacific Island Territories will not be exempt from the Tier 2 vehicle emission standards. However, additional flexibility will be
