Abstract: 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.
