What is an Environmental Assessment (EA)?
An Environmental Assessment (EA) is a document prepared by the federal government or an airport sponsor. It is consistent with Section 102(2)(c) of NEPA and is used to evaluate the potential environmental impacts of federal actions. NEPA requires federal agencies or the airport sponsor to assess the environmental effects of their proposed actions prior to making decisions. For the proposed reconstruction of Runway 2-20, an EA will be completed to assess potential effects and impacts of the proposed action. The HDOT-A is the proposing and determining agency to ensure compliance with the Hawaii Environmental Policy Act (HEPA) for airport development actions. This EA is also prepared in accordance with Chapter 343, Hawaii Revised Statutes (HRS) and Chapter 11-200.1 of the Hawaii Administrative Rules (HAR).
Why is HDOT-A proposing to reconstruct Runway 2-20?
Runway 2-20, which is constructed of asphaltic concrete, was originally constructed in the 1940s by the United States Navy. Originally used by Naval aircraft during World War II, full commercial airline operations began in June 1952. Since that time, the existing pavement and subbase have failed and requires frequent maintenance requiring runway closures. The complete reconstruction of Runway 2-20 will be designed to accommodate the critical aircraft, which is the Boeing 777-200.
