Environmental impact assessment for construction of a petrol storage tank at Gili Lankanfushi
(2014) Development Advisory Services
This EIA report is prepared in accordance with Environmental Impact Assessment Regulations, 2007 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 ecological, biophysical and human environment arising from proposed construction of a petrol storage tank at the resort of Gili Lankanfushi. The project is proposed by the management of the resort. The main construction activities of the proposed project involve construction of a petrol storage tank. As this is a relatively small tank the area to be excavated is small and no heavy vehicle is needed for dredging. It is envisaged to complete within 2 months from the start of the construction phase. It is planned to construct a tank of 11,520 litres. The tank is 1.2m in height and 4m in diameter. The tank would be situated 1m below the ground. The tank would also be surrounded by a concrete retain wall with a thickness of 75mm to retain the oil should there be a spillage. The tank will made of steel with a thickness of 6mm and also be situated close to the current staff jetty so that oil barges docked to the jetty could be used to fill the tank and refilling of the vessels could be done easily via a pipe. Need and justification of the project During certain times of the year, the demand for the fueling of the vessels increases specially with the demands for the tourist travels. During these times the availability of the petrol fueling vessels are quite demanding and experiences shortage of petrol. Even at times of emergency, it is difficult to get petrol. Therefore to address these emergencies and shortages during the high demand times, the management of Gilli Lankanfushi decided to construct a petrol storage tank so that a reserve could always be kept on the island. The tank would be refilled on a regular basis using the delivery vessels. Construction of a petrol storage tank would solve the issues of shortage and availability of petrol during times of emergencies. Key impacts Key impacts of the proposed development are related to a few activities of the project. These include impacts during the construction of the tank. Excavation, disposal of the dredged material, construction waste. There is a possibility of oil spillage and risk of fire during the operation of the tank. The impacts would be short to long‐term. Ecological impacts of the proposed project can only be assessed through long‐term monitoring of the entire island environment in relation to the proposed development and operation. Mitigation measures Mitigation measures were taken by conducting appropriate field surveys and environmental assessment of the island, proposed and alternative locations for development. Consultation among the proponent and the environmental consultants were conducted to find the most appropriate development options, methods, scale and timing in order to mitigate and minimize potential impacts due to the proposed development project. Specific measures will be taken during construction to reduce and mitigate negative environmental impact. These include selection of best location, waste minimization, civil works to be carried away from the residential areas and in shade, use of proper sign boards to inform the workers of occupational hazards during development and operation will be conducted to mitigate negative impacts that may arise from the project. Alternative development options The current location of the project site is being decided after careful considerations and several discussions with the resort management. As the northern side of the resort has a large beach it would not be the best location to host a fuel tank. On the west and the eastern side the guest room are already in place. As the existing powerhouse and the service jetty is located near the proposed site, it is chosen to be the best place to construct the fuel tank for ease of access and fueling of vessels.

This non-technical summary present the finding of the Environmental Impact Assessment of the proposed Integrated Water Recourse Management system development project at B. Dharavandhoo Island by the proponent Ministry of Environment and Energy. This EIA report is prepared in accordance with Environmental and Protection and Preservation Act and Environmental Impact Assessment Regulation 2012. The purpose of this EIA is to fulfil the requirement of the Law and to conduct an assessment of possible impacts on ecological, biophysical environment and socioeconomics arising from the proposed resort development. The main rationale of this project is to develop and operate an Integrated Water Resource Management System on Dharavandhoo Island. The specific objectives are to Development of the necessary infrastructure for the functioning of Integrated Water Resource Management System to provide safe water to the community. Implementation of the project bring economic and social benefit to the community. The project will involve the construction and operation of Integrated Water Resource Management System. Construction involves construction of operation building, installation of RO plant, construction of storage tanks, construction of water collection and distribution network, construction of infiltration galleries for ground water skimming and rain water harvesting system. Once the project is completed the Integrated Water Resource Management System will be handed to the proponent for operation. Key impacts The impacts of the project result mainly from construction activities such as land clearance, construction of the water treatment facilities, and construction pipeline network installation of brine outfall and land clearance. During construction of water treatment facilities and construction of pipeline network have negative impact to the terrestrial environment of the island. There is no significant land clearance to be carried in the project plot. Construction of the brine outfall will increase in turbidity and sedimentation which can impact the marine environment but for a short period. Baseline environmental marine conditions indicated that the live coral cover was very poor and fish count is negligibly less, showing minimum impact on marine habitat. Indirect impact may also occur from silting which is a short term impact. The major socioeconomic impact is found to be positive. Construction of Integrated Water Resource Management System will create a lot of job opportunities during the construction and operation of the system. Establishment of this project will improve public health, socioeconomic well-being of the island community and it also improves the ground water quality should there be less groundwater usage. Mitigation measures Mitigation measures were taken by conducting appropriate field surveys and environmental assessment of the island, proposed and alternative locations for development water treatment facilities and brine outfall location of the project and its associated infrastructure. Installation of brine outfall would be done during low tides to minimize the erosion and washing away of the material. The necessary announcements and proper use of sign boards will be used to minimize the difficulties caused during the construction works. A detailed hydrogeological survey of the area where infiltration gallery would be installed is suggested to be carried before construction begins. Care would be taken so as not to take any construction work near the coast. The generated waste would be stock piled on a frequent basis and waste segregation would be done to sort out the hazardous waste which will be transferred to Waste Management Centre. Moreover, a proper waste management facility would be established and the transfer vessels would be EPA approved and licensed vessels for waste handling. The water and sewerage facilities would be undergoing routine monitoring for the effluent water quality so that minimal to no damage would be done to the marine environment. Alternate locations and technology Alternative technologies of construction methods and alternative locations have also been considered during the assessment. Alternative locations for the construction of treatment facilities and alternative methodologies for the brine outfall was also considered. Some of the alternative technology are not recommended either due to expensive process or the available technology not suitable to the environmental conditions. Environmental management and monitoring An environmental management plan with environmental monitoring was developed taking into consideration the impacts and mitigation measures to be implemented. The important elements that require checks such as sediment dynamics, coral cover and water quality will be monitored according to the developed monitoring program during construction and operation period. Although the project involves inevitable negative environmental impacts, such impacts are not serve as to not undertake the project. Mitigation measures have been proposed to adequately minimize the significant impacts. Hence, the project is justifiable in light of the socioeconomic conditions and anticipated benefits from the project which clearly outweigh the negative environmental impacts.

Environmental impact assessment for establishment of an integrated water management system in R. Maduvvari
(2017-08) ޑިވަލޮޕްމެންޓޮ އެޑްވައިޒަރީ ސާރވިސަސް; Development Advisory Services
This report discusses the findings of the Environmental Impact Assessment (EIA) study undertaken by Ministry of Environment and Energy to develop a Integrated Water Resource Management (IWRM) system at the Maduvvari Island in Raa Atoll. This report is prepared in accordance with Environmental Impact Assessment Regulation (2007) under the Environmental Protection and Preservation Act (1993) and the Amendments to the EIA regulation. The purpose of this EIA report is to fulfill the requirements of the aforementioned law and regulation and conduct an assessment of possible impacts on the ecological, biophysical and socioeconomic environment arising from the proposed IWRM project in R. Maduvvari Island. The main rationale of this project is to develop and operate an IWRM system in R. Maduvvari Island. R. Maduvvari has limited capacity to for storage of rainwater and faces drinking water shortage during the dry period. The proposed system is aimed to produce and supply fresh water for the island community throughout the year. Furthermore, there is an existing sewerage system which is operational without a provision of the sewerage treatment plant, hence the groundwater lens of the island is facing saltwater intrusion due to extraction of water for flushing purpose. There are no existing mechanisms for replenishment of groundwater since the R. Maduvvari lack a proper drainage system. The proposed IWRM project includes a groundwater recharging mechanism which is expected to improve the quality of the groundwater in R. Maduvvari. The project will involve establishment of rainwater harvesting collection and conveyance system, installation and operation of Reverse Osmosis Plants and construction of a piped water network with household connections. Key Impacts The project will involve impacts both during the construction and the operational phase of the project. The main project activities which may result in impacts during the construction phase include; installation of brine reject outfall. The brine reject outfall installation is expected to have impacts on the marine habitats found in the vicinity of the location. However, there are very few live coral colonies near the proposed location for the brine reject outfall. Another main project activity which may have a significant impact on the environment include; land clearance. However, in R. Maduvvari there are very few sparely spread vegetation found in the project area. No protected trees are located in the project location. There are no major threats to terrestrial and marine biodiversity of the island due to the proposed IWRM project in R. Maduvvari. The other project activities which may have an impact include excavation and pipe works on land, impacts of machinery and equipment, impacts of the workforce and drilling of a borehole. The main project activities during the operational phase which is envisaged to have the most signifincat impact is brine disposal. However, the brine will be disposed through a brine reject outfall into open ocean which have high mixing potential due to strong currents away from the island. The other project activities which may have impact on the biophysical environment of R. Maduvvari include operation of pumps and RO plants, water treatment and disinfection, piped water network and water testing chemicals (handling & storage). The major socioeconomic impact is found to be positive. The provision of the clean and safe drinking water throughout the year will improve health of the island community. Furthermore, it is anticipated that the access to clean and safe water will increase the economic opportunities for the island community of R. Maduvvari. Mitigation Measure The mitigation measures were proposed based on conducting appropriate field surveys and environmental assessment of the R. Maduvvari Island, proposed and alternative locations for the brine reject outfall and project site. The main mitigation measures during the construction phase include ensuring proper supervision and monitoring during excavation and pipe-laying works. The installation of the brine reject outfall can be conducted only during the low tide period to reduce the sedimentation and the impacts on the marine life in close proximity to the brine reject outfall location. The impact of the machineries can be reduced by using experienced operators to conduct the excavation works. Furthermore, local contractors and employees can be employed rather than the expatriate workers which will reduce the impacts of the workforce on biophysical and socioeconomic environment of the island. Planting trees to offset the trees removed from the project site is an important mitigation measure to reduce the impacts of the land clearance. The environmental impact of drilling a borehole to obtain feedwater can be reduced by contracting experienced contractors who have extensive experience in drilling boreholes in Maldives. The main mitigation measures to be taken during the operation phase of the project include training of staff to be employed in the laboratory and operation of the IWRM system regarding safe handling of chemicals and appropriate quantities of chemicals to be used for disinfection. Another significant mitigation is installation of diffusers in the brine reject outfall which will enhance the mixing of the brine reject thus reducing impacts of the brine disposal. Alternate locations and technology Alternative systems for IWRM system, alternative to drilling a borehole and alternative locations have also been considered during the assessment. Alternative locations for the project location, location of the brine reject outfall was also considered. The alternative system to IWRM were not considered since they are found to have more significant on the environment and also costly. The alternative to drilling a borehole is to obtain feedwater from the lagoon which will increase maintenance cost and cost for desalination. The alternative location proposed will involve loss of more corals and habitats for other marine organisms and also involves removal of more trees. Environmental Management and Monitoring An environmental management plan with environmental monitoring was developed taking into consideration the impacts and mitigation measures to be implemented. The important elements that require checks such as groundwater quality, coral cover, seawater quality will be monitored according to the developed monitoring program during construction and operation period. Although the project involves inevitable negative environmental impacts, such impacts are not serve as to not undertake the project. Mitigation measures have been proposed to adequately minimize the significant impacts. Hence, the project is justifiable in light of the socioeconomic conditions and anticipated benefits from the project which clearly outweigh the negative environmental impacts.

(2018-01) Development Advisory Services
This report discusses the findings of Environmental Impact Assessment (EIA) carried out for the proposed 10 storey building at Ma. Maavelavaru, Kudhirayimaa goalhi, Malé. The objective of undertaking the project is to provide a residence to the proponent and family. The proponent also aims to rent out apartments in the building for residential use. The report has looked at the justifications for undertaking the proposed project components. Alternatives to proposed components or activities in terms of, design and environmental considerations were suggested. A mitigation plan and monitoring programme before, during and after the works has also been proposed. It is inevitable that there would be some negative environmental impacts, especially during excavation, dewatering and construction work is carried out. The potential environmental and social impacts from the overall project includes water contamination, shortage of groundwater, generation of waste, air pollution, noise pollution, disruption to traffic and interruption to commercial activities around the project location. After a survey and the study undertaken, these negative impacts identified are not severe enough to not allow the project. In light of possible impacts assessed, a comprehensive monitoring component has been suggested to monitor environmental (natural and social) impact during the course of this project. This monitoring component will be adhered and will allow the assessment of long term changes, despite the limited nature of the impact. In addition, the socioeconomic impacts that have been assessed have been identified as mostly positive impacts, not just in short term but also in long term. Therefore, from an environmental and technical point of view and in light of the existing socio-economic developments it appears justifiable to carry out the proposed project.
