The Government of the Independent State of Papua New Guinea (GoPNG) has requested the Asian Development Bank (ADB) to provide a multi-tranche financing facility (MFF) to facilitate investments to improve the current state of the country’s domestic air transport system under the Civil Aviation Development Investment Program (CADIP). Twelve major airports have been identified for improvements under Tranche 3 due to deteriorated pavement conditions and low pavement strength to ensure that these airports are capable of accommodating the current operating aircraft or similar within a safe and secure operating environment II. CADIP is a comprehensive program to improve, rehabilitate and maintain major domestic airports in Papua New Guinea (PNG) so that these airports are compliant with the domestic and international aviation safety and security standards. The executing agency for CADIP is the National Airports Corporation (NAC) who owns, operate and maintain twenty-one (21) national airports in PNG on behalf of GoPNG. III. An environmental assessment and review framework (EARF) has been prepared to guide environmental safeguards implementation for Tranche 3. In accordance with the EARF this Initial Environmental Examination (IEE) presents the environmental assessment of one of the project under Tranche 3 – Momote Runway Extension and Associated Works at Momote Airport, Manus Province of PNG. IV. This IEE has been carried out to ensure that the potential adverse environmental impacts are appropriately addressed in line with ADB Safeguard Policy Statement 2009 and the GoPNG Environment Act 2000. V. The main findings of this IEE indicate that the impacts that will arise from Momote Airport Runway Extension & Associated Works will be minimal and will be contained within the aerodrome area. The works only involve rehabilitation and improving the aircraft pavement and associated works and building a new terminal together with an airport market for duration of 18 months. The project is classified as Category B because the potential adverse environmental impacts are site-specific, few if any of them are temporary, and mitigation measures can be designed readily. VI. The potential environmental impacts associated with the project particularly occur during the construction and operation phases which will typically involve: (i) Earthworks and pavement works. During the conduct of earthworks for the terminal construction, markets and pavement works, heavy rains and the associated run-off into drains and soil erosion problems can be expected in some areas such as flight strip widening and Open Unlined Drain which may cause surface water quality problem in nearby water courses. (ii) Pollution. Problems of pollution related to the disposal of sewage, waste fuel & petrochemical products, salvage materials, oils spillage and leakage, solid wastes generated during construction (from worker camps) and operations could occur. Temporary site contamination, dust & noise generation associated with construction, and pollution associated with firefighting drills may cause environmental impacts. (iii) Noise. Construction activities may cause noise impacts from vehicle movements for a short duration. Noise from aircraft is already existing and it will be intermittent and in short duration. Significant incremental increase of flight frequency is not expected. P a g e | v VII. Adherence to best engineering practices during rehabilitation/reconstruction and implementation of the environmental management plan will avoid or adequately mitigate all of the rehabilitation/ reconstruction-related impacts. VIII. A Grievance Redress Mechanism setup in Tranche 1 and 2 will be used in Tranche 3 and the Provincial Administration are fully aware of its role. Public support during consultation for the project was unanimous and the community wanted the project to commence immediately as they seek
