dc.description.abstractThis is the first Addendum to the Environment Impact Assessment (EIA) for the harbour development (rehabilitation) project in Gahdhoo, Gaafu Dhaalu Atoll. The project is proposed by Ministry of Housing and Infrastructure. A Scoping Meeting for EIA addendum was held on 13 July 2017, following the addendum application where main issues related to the proposed change were discussed. This EIA addendum report aims to assess the issues highlighted in Terms of Reference (ToR) agreed between EPA and proponent. Furthermore it is to fulfil the requirement of the Environmental Protection and Preservation Act of the Maldives (Law No. 4/93). Construction of Gahdhoo harbour was contracted with MTCC on 08th June 2015, whereas the EIA was undertaken for this project on September 2015 by Water Solutions Pvt ltd. Construction phase of the project was commenced thereafter in late 2015. Need and justification of the harbour construction project has been described in the initial EIA. According to the EIA report, dredge material is to be used for backfilling the landward side of proposed harbour quay-wall and replenishing the beach area on south west of the island. However, during the course of the harbour project, a shore protection project has taken place in the island from December 2016 to April 2017 during which the proposed dredge material disposal area in harbour EIA report was replenished and protected by rock boulder revetment. Hence, the purpose f this EIA addendum is to allocate a new area to dispose the excess dredge material obtained from the harbour project as Gahdhoo council has requested to reclaim the area on north east of the harbour with the excess material which is expected to be 8,500cbm in total Environmental impacts of the proposed change were assessed for both construction and operation stage of the project. Most of the identified impacts are positive as they will improve the socio-economic situation of the island. As in all construction projects of this nature, the main negative environmental impact of the project is identified to be the movement and settlement of sediment around the reclamation area during the construction. However, the benthic cover of the reclamation area is predominantly composed sea grass and sand. Hence, combined negative effects are considered to be insignificant compared to the positive effects of the project with the proposed change. Effective impact mitigation measures are to be taken during the construction. It is recommended to keep the fill area enclosed with a bund wall as a mitigation measure against the movement of silt and sediments around the project area. Environment monitoring program discussed in 2015 EIA is sufficient and should be followed.. In an environmental and technical point of view, the proposed change to Gdh. Gahdhoo harbour rehabilitation project of is justified and beneficial in number of ways.en_US
