Item First addendum to environmental impact assessment for harbour development project at M. Dhiggaru(2016-10) Water SolutionsThis report discusses the findings of a study undertaken as an addendum to environmental impact study undertaken by Ministry of Housing and Infrastructure for the harbour development project at M. Dhiggaru at the request of Ministry of Housing and Infrastructure. This Fist Addendum to EIA for the Harbour Development Project at M. Dhiggaru report covers fishing vessel beaching area to be developed as additional work for the harbour development project currently being implemented at M. Dhiggaru. This EIA Addendum report is prepared in accordance with Environmental Impact Assessment Regulations, 2012 under the Environmental Protection and Preservation Act (Act No. 4/93). The purpose of this EIA is to fulfill the requirement of the Law and to conduct an assessment of possible impacts on environment arising from the proposed fishing vessel beaching area at M. Dhiggaru. The project is at the island of Dhiggaru in Meemu atoll. The island is located at the northern edge of the Meemu atoll. The island is situated in a large reef system. The closest island to Dhiggaru is Madduvari which is about 1 km to the east of Dhiggaru. The harbour development project is proposed by Ministry of Housing and Infrastructure representing the government of Maldives and the Ministry is responsible for all development and regulation of the construction sector. The contractor for the project is Maldives Transport and Contracting Company (MTCC). The beaching area for the fishing vessel has been proposed as an extension of the harbor development project at M. Dhiggaru. Currently there is no area for beaching of vessel at the island. This has caused a lot of difficulty for the fishing vessel to undertake dry dock repairs which is routinely required. The island has a population size of approximately 1300. The main economic activity of the island is fishing1 The island of Dhiggaru is famous for “dhiggaru rihaakuru” which provides a good economic income to the community. The project involves dredging of 60 m by 45 m basin area to a depth of -3.0 m MSL, an entrance channel of 20 m wide and 117 m long. The dredging is expected to generate 12,600m3 of dredged material. This dredged material would be used to reclaim 8,400 m2 of area on western side of the island. The new land created would be used for boat repair work. All project activities will be in conformance to the laws and regulations of the Maldives, and relevant international conventions that Maldives is party to. The key laws and regulations applicable to this project are Environmental Protection and Preservation Act and Environmental Impact Assessment Regulation 2012 and its subsequent amendments The study for the addendum to EIA was undertaken to assess the environmental impacts of changes to the harbour development project on the island. The proposed site (lagoon) and entrance channel had no visible live corals and was highly turbid. seagrass is found at the lagoon. Based on the assessment, it has been identified that the major impacts of the project will be felt on the marine environment during the construction stage. Dhiggaru is not a large inhabited island but located on a very large reef system. The development of the beaching area on the island will have impacts on marine environment. During the operational stage, environmental concerns are much less and are associated with waste and wastewater management of the fishing vessels. The mitigation measures are provided in the report with alternatives. It is vital to conduct the activities, during both construction and operational stage, in line with mitigation measures emphasized in the report. Socio-economic impacts of the proposed beaching area development project will help the community to beach their vessel onto the island for dry dock maintenance work. This project will create economic opportunities both in the construction and operational stage through creation of both short-term and permanent jobs and business opportunities. Towards the end of the report, a monitoring programme has been suggested which covers components of coastal and marine environment. It is important to follow this monitoring programme not only to comply with the regulation but also to ensure that the impacts are measured in realistic terms.Item Environmental impact assessment for undertaking sand dredging at Gulhifalhu jetty area, Gulhifalhu, Kaafu Atoll(2016-10) Water SolutionsThis report discusses the findings of an environmental impact study undertaken by Water Solutions Pvt. Ltd. for Gulhifalhu Investment Ltd. The project involves maintenance dredging of the Gulhifalhu Jetty area. The project aims to: Deepen the existing jetty basin Provide safety and protection to the vessels accessing the jetty area Increase the usable area of the jetty Gulhifalhu is an industrial island which lease land plots for different industrial purposes. Many private vessels travel Gulhifalhu to access their sites every day. There is an existing jetty area in Gulhifalhu that is used by these vessels to access the island to load and unload materials. However, now the jetty basin is very shallow due to accumulation of sand in the basin. Some areas of the basin are less than a meter deep making it impossible to moor vessels to jetty. This project aims to dredge this area to provide a safe basin and larger accessible area. Approximate total of 9000 cbm of sand will be dreged from this area. This sand will be stockpiled temporarily in Gulhifalhu and then will be transported to Thilafushi MRDC site for later use. Environmental impacts of this project were assessed and have been identified as resulting from the dredging works. Dredging work will be undertaken using excavators and sand pumps and this is particularly a method that creates lot of sedimentation which is a big threat to the marine environment. Mitigation measures for the negative impacts have been identified and outlined in the report. Completing the dredging works in the shortest time frame and in low tide hours is a significant mitigation measure to minimize the impact of sedimentation on the marine environment. In addition, dredging should be avoided in bad weather conditions. The proposed mitigation measures will have to be followed in order to minimize environmental damage. The measures proposed to minimize or mitigate environmental impacts may be considered to be appropriate, thereby minimizing the impact by about 90%. The main negative environmental impact of the proposed project would be sedimentation and destruction of the lagoon and damage to some areas of the nearby reefs, which will cause partial death of corals in other areas of the coral reef. During dredging works, the sedimentation will also affect the fish species in the vicinity of these areas and hence, their population will drop in areas affected by sedimentation. It is inevitable that there would be negative environmental impacts of this project. As a result, a mitigation and monitoring component has been suggested which takes into consideration, the most important elements that require monitoring, most importantly a mechanism and means to measure and value the social benefit of the project. This monitoring component will be adhered and will allow the assessment of long term changes, despite the potential negative impacts. The dredging of Gulhifalhu jetty area does pose some threats to the marine environment of the area. There will be direct and indirect damage to marine environment in the vicinity of the project site. However there are many positive benefits of the project in long term. This project is justifiable in the light of the positive impacts.Item Environmental impact assessment to upgrade/renovation of vessel loading jetty at STO go-down (plot no 2) and shore protection of the (plot no 111), at K. Thilafushi, Maldives(2016-11) Development Collaborative Partnership1- This is the Environmental Impact Assessment (EIA) report carried out for the State Trading Organisation (STO) for the proposed upgrade/renovation work for vessel loading jetty at STO go-down (plot no 2) and shore protection work (plot no 111). The project involves removal of existing quaywall, Extension of shoreline 20m from the existing quaywall boundary, sheet pilling and back filling Plot No 2. Main renovation work in Plot no 111 involves removal of existing seawall and construction of a new revetment by using rock boulders. The EIA was prepared as fulfillment of the requirement by the Environmental Protection Agency under the dredging and reclamation regulation (Regulation 2013/R-15) for granting permission for the project. Environmental Impact Assessment (EIA) of development projects is a requirement by the Environmental Protection and Preservation Act (EPPA) (law 4/93) of the Government of the Republic of Maldives. 2- This report has been prepared in accordance with the Environmental Impact Assessment Regulations published by the Ministry of Environment and Energy 2012 and covers both negative and positive environmental and socio-economic impact arising from the proposed upgrade/renovation work for vessel loading jetty at STO go-down (plot no 2) and shore protection work (plot no 111). Major findings of this report are based on information gathered during the field inspection of both the existing environment and possible effects of the project activities, through extensive literature review and experiences gained from similar projects elsewhere in the Maldives. 3- The proposed project activity will take place in K Thilafushi Industrial Island Plot no 2 and Plot no 111. Thilafushi is located at the west of Gulhifalhu and east of Giraavaru Resort. The island was initially reclaimed for land fill purposes, but has been further developed to carter for industrial use. The reclaimed island was later turned into the industrial hub of the Maldives and a larger proportion was reclaimed by sand filling from the inner lagoon. The industrial potential of Thilafushi grew big and Thilafushi Corporation was formed in 2009 to change the garbage island to the potential industrial hub for light and heavy industrial needs. 4- During the preparation of the EIA report an impact matrix, which is a standard tool for identifying the possible impacts of project activities, has been created for proposed upgrade/renovation work for vessel loading jetty at STO go-down (plot no 2) and shore protection work (plot no 111). The activities carried out during the construction and postconstruction or operational phases are arrayed against a selection of environmental factors that may be affected directly or indirectly as a result of project activities. 5- The environmental impact assessment study for the proposed upgrade/renovation work for vessel loading jetty at STO go-down (plot no 2) and shore protection work (plot no 111) shows there are two main activities that would cause significant negative environmental impacts are pile driving, backfilling, seawall construction and concrete work in Plot 2 and Coastal protection work (construction of rock boulder revetment) in Plot 111. 6- Of these a long term impact would be from pile driving, backfilling, seawall construction and concrete work in Plot 2. Sedimentation on lagoon and reef physical damage to benthic fauna and habitat loss and change in near shore flow pattern are some of the impacts. These impacts would be cumulative occurring over long period of time and so can be managed through proper monitoring. Based on the scale of coastal protection projects that is taking place in Maldives, impacts associated with this activity is insignificant. 7- Construction of rock boulder revetment adjacent to the shoreline will temporarily increase the sedimentation on the north eastern side but the impact would be short term and negligible. However, the positive socio economic impacts from the proposed development outweigh the temporary negative impacts of project. 8- The study has evaluated alternative options for the project activities and evaluated potential option of alternative sources for fill material, alternative coastal protection structures. Based on the similar project activities elsewhere in the Maldives the report found, that the Thilafushi will recover from the impacts will re-establish a new ecological balance soon. Even though there is no very significant impact from this project after the report has come-up with an extensive monitoring programme that will keep on monitoring coastal and marine environmental changes associated with the project and make necessary adjustment based on the findings of various measured environmental parameters suggested in the monitoring plan. 9- The study found that the proposed project is in line with key legal and policies maintained by the Government authorities and EPA including Environmental Protection and Preservation Act, EIA Regulations, and land-use plans developed for Thilafushi Industrial Island by Thilafushi Cooperation. 10- Therefore on the basis of this environmental impact assessment study and the impact mitigation measures proposed in the report will be duly implemented and recommendations are given due consideration, it is concluded that the benefits of the proposed upgrade/renovation work for vessel loading jetty at STO go-down (plot no 2) and shore protection work (plot no 111) in Thilafushi will substantially outweigh its imposition on the environment
