The Pacific Island Network includes islands at diverse locations in the Pacific Ocean. It includes the Hawaiian Islands, Northern Mariana Islands, Guam, and American Samoa. This analysis focuses on the parks in Hawaii. Figure 14.1 shows the Pacific Island Network boundaries across the Hawaiian Islands, along with locations of each park and population centers with more than 10,000 people around the network. There are nine parks in the Pacific Island Network. This chapter focuses on Hawaii Volcanoes National Park (HAVO) and Haleakala National Park (HALE). Only one, HAVO, is larger than 100 mi2 (259 km2). It is located on the island of Hawaii. HALE and HAVO are Class I air quality areas, which receive the highest level of protection under the Clean Air Act from effects attributable to poor air quality; the rest of the Pacific Island Network parks are Class II areas. The NPS air quality efforts focus largely on the Class I areas, but all national parks are protected. The only population center in the Pacific Island Network region of any magnitude (more than 100,000 people) is Honolulu on Oahu. Figure 14.1 Network boundary and locations of parks and population centers with more than 10,000 people within the Hawaiian Islands in the Pacific Island Network region.
