Item Environmental impact assessment report development of 100 bed hospital at Addu City(2017-10) Land and Marine Environmental Resources Group1.1 Background The non-technical summary outlines the findings of the Environmental Impact Assessment of the construction and development of a 100 bed tertiary level hospital at Hithadhoo, Addu City. The proponent of this project is the Ministry of Housing and Infrastructure and total estimated cost of the project is approximately MVR 162 million. The proposed project will be developed through redevelopment of the Equatorial Convention Centre which was developed in Addu City to host the SAARC Summit in 2011. Parts of some ponds introduced for aesthetic and flood control purposes within landscaping of ECC development would be backfilled for the construction of the Services and Utilities buildings on the south western and south eastern side of the main building. Once completed, the hospital will be handed over to the Ministry of Health, as the main operator and regulator of the Health sector in the Maldives. The facility will be constructed and developed to provide care in a number of departments and areas, details of which are provided in Section 5.2.1. 1.2 Key impacts, mitigation measures and alternatives Impacts on the environment from various activities of the project development work (constructional impacts) and operational impacts have been identified through interviews with the project management team, field data collection and surveys and are also based on past experience of consultant in similar projects. Impacts were analysed for their significance with the aid of a Leopold Matrix. In any development project, major direct impacts to the environment occur mainly during the construction phase. Potential direct or indirect impacts on the environment from the proposed project include: Moderate impacts on pond water and groundwater resource due to backfilling works; Minor impact on vegetation due to the need to cut down vegetation located at the plots allocated for construction of infrastructure; Impact due to air and noise pollution during construction work; Impact due to flooding within vicinity Impact due to waste generation, especially during operational phase Risk of accidents on hospital staff and patients Positive impact on social wellbeing and health due to provision of good quality care Mitigation measures are discussed for the activities which would have potential impacts during the construction and operational phase of the project. In general, during the construction stage it is important to use a method of construction which has the least impact on the environment. Specific measures highlighted include: • Preplanning ways so as to expose backfill material sourced from MRDC, Addu City to rainfall, to decrease its salinity • Proper waste management and disposal to mitigate issues due to domestic waste and hospital related biohazardous waste • Establish Standard Operating Procedures for all departments and facilities at the hospital, so as to avoid accidents which pose risks to the staff and patients Detailed mitigation measures are discussed in Section 11 of the report. Alternatives has been considered with respect to project location, as there is disagreement from the Council regarding proposed location. While proposed location is an existing structure and thus project development would have minor impact on environment, it is also considered by the island community as a site of significance and hence do not want to turn the facility into a hospital. The no-project scenario is also considered, which would mean that all environmental impacts due to the project and disagreements regarding use of ECC for the project would no longer be an issue. However, this means that health care for the population of Addu City will be provided as is now, through the Regional Hospital, which does not offer all of the facilities as proposed in the project. Hence, the community would not benefit from many benefits offered through better health care facilities and services offered through the project. The environmental impacts predicted for the project are minor to moderate, given that the project development is mainly at an existing structure. Hence the benefits of developing the hospital and better health care facilities outweigh the cost to the environment and are seen to be far more beneficial than the cancellation of the project. Therefore the “no-project” scenario is not an ideal solution and it is recommended that the project be continued, but with the proper implementation of all mitigation measures proposed in the report. One key recommendation of the consultant is the formulation and implementation of regulations which regulate the healthcare sector, especially those related to development of healthcare facilities (and criteria) and waste disposal from healthcare facilities. This is crucial for the improvement of the sector through both proper service provision and mitigating environmental impacts.Item Environmental impact assessment report agricultural development project at Hulhidhoo, Vaavu Atoll(2017-11) Land and Marine Environmental Resources Group1.1 Background The non-technical summary outlines the findings of the Environmental Impact Assessment of the proposed agricultural development at Hulhidhoo, Vaavu Atoll by Aarah Investment Pvt Ltd. The capital cost of the project is MVR 10.43 million. 1.2 Project Detail The proposed project involves the development of Hulhidhoo as mix-use island with an agricultural and tourism component. The agricultural component of the project utilizes hydroponics technology with a vertical farming system to cultivate vegetables and herbs. The produce will be supplied to resorts within the Atoll. The tourism component of the project involves the construction of a Water Sports Centre at the western side of the island. This will cater to the resorts, and can also be used by the atoll community, if desired. In addition to the two key components, the project also involves construction of a football court and coffee shops on the island. 1.3 Key impacts, mitigation measures and alternatives 1.3.1 Key impacts Impacts on the environment from various activities of the project development works (constructional impacts) and operation of the facility (operational impacts) have been identified through interviews with the resort management, field data collection and surveys and are also based on past experience of consultation in similar development projects, as well as a review of similar projects. Impact analysis was done using the Leopold matrix. The potential direct or indirect impacts on the environment (on land and reef system) from the proposed project include: ➢ Moderate direct impacts on the marine ecosystem quality due to construction of access jetty (piling works) ➢ Major impact on terrestrial environment due to need for vegetation, especially that at the mangrove area ➢ Minor impact on groundwater due to dewatering during construction stage and use of septic tank system during operational stage ➢ Minor impact on seawater quality due to brine discharge during operational phase ➢ Impact on ecosystem and air quality, due to solid waste generation during construction and operational phase Positive impacts due to the project are the positive social impacts, in terms of job availability especially during the operational stage. The training programmes for the Atoll community in the area of hydroponics also opens opportunities for new business ventures. The open access to the water sports centre and football pitch is a major social benefit, as this promotes a more inclusive development. Furthermore, the implementation of the solid waste disposal programme by the proponent as a part of the CSR component of the project, is a major benefit for the community, as it addresses a key issues being faced by all islands communities of Maldives. Overall, the project has a positive impact, on the national economy, and that of the Atoll community. Additional impacts are discussed in Section 9 of the report. 1.3.2 Mitigation measures The severity of impacts is predicted by reviewing the design plans and construction methods. Mitigation measures are formulated in light of the findings by the project engineers (for the different methods to be used during the construction phase). Mitigation measures are discussed for the construction and operational stage of the project. During the construction stage it is important to take measures to minimize impact on the environment due to the various construction methods. A construction method that has the least impact on terrestrial and/or marine environment has to be utilized. Detailed mitigation measures are discussed in Section 11 of the report. 1.3.3 Alternatives Considering the alternatives for the project in terms of location and type of economic activity to be carried out has been decided by the Ministry of Fisheries and Agriculture and the proponent, through lease of the island to the proponent for a specific purpose. Apart from the type of economic activity and location, other aspects for which alternatives have been considered in the report are: ➢ Construction method of jetty ➢ Location of M&E facilities building ➢ Feed water intake method Details of the various alternatives considered and the selected alternatives are shown in Section 10 of the report. Of these, the location of M&E facilities building is of significance, as the alternative location greatly minimizes the impact due to vegetation clearance, as it offers the opportunity to avoid clearance from the mangrove area. Thus, from an environmental aspect the consultant strongly feels the alternative location is the more feasible option and thus this option is selected. The no-project scenario is also considered, which would mean that all environmental impacts due to the project would no longer be an issue. Environmental impacts due to the proposed project are minor to moderate overall, while discontinuation of the project means a loss of income and revenue to the proponent and the national economy, as well as a loss of number of benefits for the Atoll community. Hence, it is concluded that continuation of the project with the implementation of the different mitigation measures to minimize environmental impacts is a feasible option.Item Environmental impact assessment harbor construction works at Maduvvaree, Raa Atoll(2015-12) Land and Marine Environmental Resources GroupBackground The non-technical summary outlines the findings of the Environmental Impact Assessment of the proposed harbor construction at R. Maduvvaree. The proponent of the proposed project is Ministry of Housing and Infrastructure. The total estimated cost of this project is USD 1.45 million. The proposed project involves construction of the harbor facility on the southern side of R. Maduvvaree. The harbor will have dimensions of length 211m and maximum width of 86m. The entrance will be from the existing entrance on the south eastern end of the facility. Key impacts, mitigation measures and alternatives Impacts on the environment from various activities of the construction work and during the operation of the facility have been identified through interviews with the project management team, field data collection and surveys and are also based on past experience of consultant in similar development projects. Mitigation measures have also been identified for impacts which are irreversible in nature. Impact analysis was done using the Leopold matrix. Impact analysis showed that impact due to the project was due to dredging works which is anticipated to have a moderate impact on marine habitats as a result of sedimentation. Positive impact foreseen is availability of safe harbor for the fishing fleet of the island and additional of land area. Other minor to moderate impacts are discussed in section 9 of the report. Mitigation measures are discussed in the report for potential impacts, including mitigation for the event that the project might be stopped prior to the completion of all works. In such cases, it is advised to ensure that the mitigation measures outlined for this scenario in Table 9 are implemented prior to the departure of contractors. Detailed mitigation measures are discussed in Section 11 of the report. Alternatives have been considered for various components of the project and are given as possible options that may be either more practical or less expensive to the preferred options. The proposed alternatives also have taken into consideration the environmental consequences resulting from these options as compared to the preferred options. The following components of the project have been discussed in providing their alternatives; Equipment/method used for dredging Location of harbor The “do-nothing” option or no project scenario would mean that the large fishing vessel fleet of island would face the same existing difficulty of not having appropriate berthing and safe harbor. However, the no-project scenario also means that the environmental impacts due to the project, which are moderate in terms of the impact on live coral cover and marine habitats, will be completely avoided. The existing facility is in need of repair; the outer breakwaters are damaged and does not properly stop waves during NE monsoon. Hence the community feels that southern area is adequate for a harbor, furthermore the area is already dredged therefore cost for construction will also be lower. Therefore given that the benefits of construction of the facility are more significant than the environmental impacts, continuation of the project is considered feasible with proper implementation of the mitigation measures proposed to minimize the impact on the environment. Details of the various alternatives considered and the selected alternatives are shown in Section 10 of the report.Item Environmental impact assessment swimming area development at Bodufolhudhoo, AA Atoll(2015-11) Land and Marine Environmental Resources Group1 Non-technical Summary Background The non-technical summary outlines the findings of the Environmental Impact Assessment of the proposed swimming area development in AA Bodufolhudhoo. The proponent of the proposed project is Bodufolhudhoo Island Council. The total estimated cost of this project is MVR 200,000.00. The proposed project involves dredging the sea grass meadow at the south eastern side of Bodufolhudhoo and creation of a recreational beach and swimming area for community use. Key impacts, mitigation measures and alternatives Impacts on the environment from various activities of the construction work and during the operation have been identified through interviews with the island council, field data collection and surveys and are also based on past experience of consultant in similar development projects. Possible impacts arising from the project are categorized into reversible and irreversible impacts. The impacts identified are also described according to their location, extent and characteristics. Mitigation measures have also been identified for impacts which are irreversible in nature. In any development project major direct impacts to the environment (either short-term or long-term) occur mainly during the construction phase, while some impacts are inevitable during the operation stage. Impact analysis was done using the Leopold matrix. Impact analysis showed that the project is envisaged to have minor impacts on the environment due to dredging works at the proposed swimming area (sea grass meadow). Positive impacts due to the project are anticipated to be few, including availability of recreational beach and swimming area for the community and guest operations at the island. Other positive impacts include potential indirect income opportunities in the future through the development of guest house industry. Other impacts are discussed in Section 9 of the report. Mitigation measures are discussed in the report for potential impacts, including the reclamation of a sand bund at the outer perimeter of the swimming area to reduce extent of sediment plume. Detailed mitigation measures are discussed in Section 11 of the report. Alternatives have been considered for various components of the project and are given as possible options that may be either more practical or less expensive to the preferred options. The proposed alternatives also have taken into consideration the environmental consequences esulting from these options as compared to the preferred options. The following components of the project have been discussed in providing their alternatives; Equipment/method used for dredging Location of swimming area Location of dredged material disposal areaThe no-project scenario is also considered, which would mean that all environmental impacts due to the project, which is minor in terms of the impact on live coral cover and marine habitats would no longer be an issue. Given the minor environmental impacts, positive impacts outweigh the negative in terms of positive social impacts. Hence discontinuation of project is not seen to be feasible. Details of the various alternatives considered and the selected alternatives are shown in Section 10 of the report. The consultant feels that the project with its minimal impact on the environment is feasible and can be continued with the implementation of proper mitigation measures as outlined in the report.
