INTRODUCTION 1. The Government of Papua New Guinea (PNG) has asked the Asian Development Bank (ADB) to provide a loan to fund the Government’s project to expand Lae Port: the Lae Port Development Project. The proposed Project is included in ADB’s pipeline as a firm project for approval in 2007. PNG Ports Corporation Limited (PPCL) will be the Executing Agency. 2. The Project will include development of a tidal basin, multipurpose berth, and terminal works. According to the PNG Environment Act 2000, the Project is a level 3 activity and therefore requires the approval of the minister for environment and conservation on the basis of an environmental impact statement, which is referred to in this report as the environmental impact assessment (EIA) report. According to ADB’s Environmental Assessment Guidelines (2003), the Project is classified as category A and needs to have an EIA. 3. This summary environmental impact assessment (SEIA) summarizes the major findings of the EIA report. The EIA and environmental management plan were prepared by Haskoning Nederland BV (Haskoning), engaged under ADB technical assistance to prepare the project.T1 The EIA report was prepared in accordance with the relevant laws and Government regulations. The EIA and environmental management plan reports, in principle, cover all the requirements set out in ADB’s Environmental Assessment Guidelines. II. DESCRIPTION OF THE PROJECT 4. Lae Port is situated on the coast of Huon Gulf (Map 1), where depths may exceed 900 meters (m). The largest PNG port, it is centrally located in the country and on most Pacific shipping routes. The current five berths are aging and insufficient to handle increasing cargo volume and vessel size. The Lae Port Development Project comprises extending the existing berths by constructing a tidal basin and associated deepwater wharf and container terminal, located to the west of the present port site. The tidal basin will be excavated in the coastal marshland. 5. The Project includes construction of a tidal basin (700 m long and 400 m wide) with a dredged depth of 13 m below chart datum, a multipurpose berth (240 m long and 45–50 m wide), and terminal works including all buildings; storage area; roads; and drainage, water, electrical, and sewerage services. The tidal basin and berth are designed to accommodate vessels with an overall length of 200 m, beam of 32.2 m, and fully laden draft of 12 m. Flexibility is built in for extending the berth by another 150 m without incurring dredging cost. The location of the Project is shown in Map 2 and the layout of the tidal basin in Map 3. 6. Preconstruction Phase. Prior to the commencement of dredging activities, the future port area (120 hectares [ha] of secondary growth vegetation cleared in 1980) will be cleared of all vegetation. Tree stumps of approximately 0.5 m will be left to facilitate the grubbing and removal of tree roots by bulldozers, and will be collected in a temporary storage area (3 ha). 7. Construction Phase. About 6.5 million cubic meters (m3) of material will be removed to develop the future port area. The material to be dredged to create the future port basin can be classified as (i) unsuitable material (3.4 million m3) originating from a 5 m thick clayey, peaty upper layers, and (ii) suitable fill material (3.1 million m3) originating from the lower sand-gravel 1 ADB. 2006.

About 1.7 million m3 of suitable material is required for the necessary reclamation works, leaving approximately 1.4 million m3 to be stockpiled within the cleared area for future use. 8. For dredging, reclamation, and disposal, a cutter suction dredger (CSD) will be used, with the following support facilities: workboat, floating pipeline, land pipeline, submerged pipeline, survey boat, bulldozer, loader, and spreader barge. For transport of the dredged material, a pipeline system will be installed. During dredging, shore connections with the floating pipeline will be made as required and placing of fill will start from the northern part of the reclamation area to the south. Part of this pipeline will also be used for disposal of unsuitable material, in which case a submerged pipeline will extend from the south western end of the pipeline to the spreader barge. 9. The suitable material provided by the lower soil layers of the area to be dredged will be used for constructing the port basin and other structures proposed by the Project. Quantities of rock material required would be limited, therefore quarry stone is not being considered as a construction material for the Project. For slope protection and construction, both gravel and aggregates for concrete and cement are available at Lae. For reclamation of the future port areas, the suitable dredge material will be used. The quantities of suitable material dredged will be in excess of the quantity required for port development.
