Item Environmental impact assessment : for the removal of seagrass beach replenishment activities in Herathera Island Resort, Addu atoll, Maldives(2010-09) CDE ConsultingThe Herathera Island has been experiencing seaweed overgrowth for a number of years, even before construction began on the island. Similarly, the island does not have a natural beach system which is suitable for a resort product. An attempt was made in 2007 and 2008 to remedy these shortcomings by removing seagrass and undertaking beach replenishment. Unfortunately, the beach replenishment design and implementation was flawed and new seagrass colonies have started to emerge. The island is currently is a worse condition, particularly its beach system. These environmental issues are decreasing the economic value of the tourism product being offered Resort and is reaching a point where the product may be unviable. Immediate action is required to address these issues, thus, a new and improved beach replenishment and seagrass removal programme. The proposed project involves the removal of sea grass colonies and beach replenishment. Details of the proposed project components are outlined below. a) Sea grass removal The primary component of the project is seagrass removal. Seagrass areas covering approximately 200,000 – 250,000 m2 is proposed to be cleared (see Site plan in Appendix B), 100,000 m3 of dredge waste. TwoEIA for the proposed Seagrass Removal and Beach Replenishment Activities in Herathera Island Resort Prepared by: CDE Consultancy Page| ix methods have been proposed for the project: 1) using a sand pump; 2) using an excavator and; 3) soft measures. b) Beach Replenishment Beach replenishment has been considered as part of the project to mitigate the severe erosion on the island. The dredged waste from the sea grass removal activity, after cleaning and sorting, will be used to replenish the a 2900 m beach up to 10 m from the existing shore line. Additional sand will be dredged from borrow areas within the lagoon using sand pumps and excavators. Replenishment will be carried out using a three staged process. The first stage will collect and filter sediments on designated sites. The second stage will transfer the cleaned sediments to severe erosion zones using trucks. The final stage will profile the beach using fine sand. For the direct replenishment, sand will be pumped or transferred via barges to a designated location, where loaders and trucks and move the material.Item Environmental audit for registration of existing desalination plant and improvement to existing football ground at Kuredu Island Resort Lhaviyani Atoll, Maldives(2011-05) CDE ConsultingThe purpose of this Environmental Audit report is to fulfill the requirements of the Environmental Protection Agency to carry out the registration of the powerhouse, desalination plant and improvement of existing football ground in Kuredu Island Resort, Lhaviyani Atoll, Maldives. The power generation system involves a powerhouse building that houses seven diesel fired generator sets with total capacity of 4585 KVA and a fuel storage facility with total capacity of 240,000 litres. Desalination system involves three plants with a total capacity of 210 tonnes of desalinated water per day and two water storage tanks with storing capacity of 1040 tonnes. The project involves improvements of the existing football ground which is dedicated to the staff purely for their recreational purpose. The major development proposed for this football ground is to level off the ground install drainage system. The structural integrity of the facilities is considered good. Noise levels are perceived as high for a mixed residential and industrial zone although it must be taken into account that space is limited and location of staff areas near powerhouse is inevitable. The main environmental impacts associated with this project include, increased noise levels and other emissions, potential risk for ground water and soil contamination due to fuel spills and leaks, damages to vegetation due to heat and smoke generated from the power house, potential impact on the marine environment due to brine discharge from the desalination process. Visual observation identifies no notable damage to existing vegetation around the powerhouse building and no indication of any fuel spills around the powerhouse area. Marine water quality tests identify no significant contamination. Groundwater quality tests are insufficient to draw conclusions. Improvement to the football grounds is not expected to cause significant adverse impacts. Drainage of water during operation phase will positively affect the groundwater aquifer by contributing to recharging of the aquifer. Mitigation measures that are in place to reduce the environmental impacts associated with the operation of the two facilities include planting of trees in high noise areas and improved maintenance of generator sets.In order to protect the environment from potential fuel spills, fuel storage facilities are bunded to contain any spills and proper pipelines are established for safe fuel transfers. A monitoring plan is proposed to observe any changes taking place due to the operation of powerhouse and desalination plant. In the event that monitoring indicates that any environmental quality is deteriorating to unacceptable levels, the proponent will correct operation procedures that are contributing to the problem and/or undertake necessary engineering installations.Item Environmental impact assessment report for the proposed land reclamation (phase III) of the Gulhifalhu Island, Kaafu Atoll, Maldives(2011-09) CDE ConsultingThis Environmental Impact Assessment (EIA) is an evaluation of the potential environmental, socio-economic and natural impacts of the Gulhifalhu Devleopment project Phase Ill. The Project is being undertaken by Capital Investment and Finance Ltd (CIFL) registered in the UK. CIFL has signed a concession agreement with the owner of Gulhifalhu - Gulhifalhu Industrial Zone Limited - a state-owned company with objective to privately develop a qualitatively high and attractive residential and commercial area in the Maldives and lease out reclaimed land for 35 years. The planned 10 Ha reclamation under the first phase of the project has been completed.Item
