Item Environmental impact assessment for the development of a new power house at G.Dh. Thinadhoo(2016-06) Abdul Wahhab, Mahfooz; Jaleel, Mohamed Ibrahim; Shareef, Ali1. The purpose of this EIA is to critically analyse and assess the potential environmental impacts associated with the development of new powerhouse at G.DH Thinadhoo and expose the solutions and preferred alternatives as well as mitigation measures to minimize any negative impacts whilst trying to derive the maximum positive impacts from the project. 2. The powerhouse in Thinadhoo was recently burned down by an accidental fire. The powerhouse was burned to the extent that the building can no longer be used. The fire has greatly reduced the strength of the walls and concrete beams of the building, considering the health and safety of the staff that work in the powerhouse it is not advisable to repair the building and continue operations. Therefore, a new powerhouse is proposed to be developed in Thinadhoo. 3. In this powerhouse development project, a new powerhouse is proposed to be constructed within the FENAKA premise. The powerhouse will be constructed from pre-fabricated sheets and blocks. The project will also involve the construction of admin building, fuel storages and the transfer of generators from the existing temporary powerhouse to the new powerhouse. The generator beds will be rolled over metal rollers to the new powerhouse. All the components of the powerhouse will be constructed according to BS standards complying to both MEA and EPA regulations. 4. Thinadhoo is located on the western edge of Huvadhoo Atoll. Thinadhoo is the most densely populated island in G.DH atoll. According to census 2014 the total population of Thinadhoo is 5268. 5. A full baseline of air quality, water quality and noise level was established. It was found that the water at the powerhouse location had very high conductivity which may be due to its close proximity to the coast. Noise level within the vicinity of the temporary generators is very high, it was concluded that the noise level is high because the generators were not inside a sound attenuated powerhouse. Air quality measurements at the existing temporary powerhouse and proposed powerhouse revealed that only air pollutant Nitrogen dioxide was found at 2 ppm concentration near the exhaust chimney of the existing temporary powerhouse.The construction works of new powerhouse presented in this report are not expected to adversely impact the environment if the mitigation measures mentioned in the report are followed. The most important mitigation measures are to do daily maintenance of machinery, following chemical handling procedures, waste segregation and storage in closed labelled containers until disposal to Thilafushi and most importantly following the fuel handling plan 7. It is expected that the newly established powerhouse will ensure reliable electricity services to Thinadhoo. And also will greatly reduce any smoke and noise disturbance to the community and the environment. 8. The major potential negative impact for this project is groundwater contamination from chemical spills and oil spills during fuel handling. Therefore, handling of fuel or other chemical substances has to be done according to the fuel handling plan. The major potential positive impact from the project is the reliable supply of electricity services to Thinadhoo. 9. Monitoring is essential to ensure that environmental thresholds are not exceeded and mitigation measures proposed are working. Water quality and air quality monitoring will be done according to the monitoring schedule. 10. The no project scenario will mean that the new powerhouse will not be developed in Thinadhoo and would lead to reduced reliability of electricity services to Thinadhoo. One alternative location, west side of island along with the proposed project location was analysed. It was found that the proposed project location is the preferred alternative based on socioeconomic and environmental factors.Item Environmental impact assessment for the proposed aquaculture project at Maroshi, Shaviyani Atoll(2016) Shareef, AliThis EIA report has been prepared to fulfill the legal obligation to obtain environmental clearance under Environment Protection and Preservation Act (4/93) of the Maldives and has been structured to meet the requirements of the EIA regulations 2012.the Environmental Protection Agency. The project proponent is Adil Mohamed, NID no. A022975. A 40,000 sq feet area has been leased out for ten years to develop out a hatchery and use lagoon as a grow out area. The project will be carried out in Sh. Maroshi on the east side of the harbor. The project is to commence as soon as the EIA is approved and the duration of the project will not be more than 12 months. It is estimated that the project will be in first grow out trials by the end of 2nd year of operation. A hatchery unit with algae culture and larvae culture units will be established. Concrete tanks with transparent roofing will be constructed. A small laboratory and stock culture room will be established. All water quality testing and lab equipment’s will be purchased before the initiation of the project. Major project impacts have been identified in this report which includes loss of benthic habitats and impact due to production of waste and effluent. This have to be considered given the fact that currently the islands bay area holds hundreds of Holothuria scabra of varying size and maturity levels. However the lagoon area needs to be utilized on a gradual manner. The project activities including construction would be carried out with a maximum of 12 months from the initiation which would take place after the approval of the EIA. Proper safety precautions will be carried out at the work sites. Necessary hygiene protocols will be set up for hatchery management. Waste water is the major waste product. This water will be filtered through sedimentation tanks. In addition sand filters and chlorination of waste water will be carried out. Domestic and construction waste will be gathered and transported to islands waste management center. Power supply will be obtained from islands power plant maintained by FENAKA. Rainwater will be harvested to be used for staff and hatchery needs. A small desalination plant would be placed to produce the volume of water needed. The inlet and outlet of the plant would be placed in the lagoon in front of the hatchery area but with a distance apart. Since the area in front of the hatchery is dominated by dead coral and rubble, the impact by discharge water would be less to negligible. The correct feeding ratio needed to feed the juveniles would be utilized so as to minimize any impact that may arise due to eutrophication. And the volume of the population of the juveniles and stock will be controlled to maintain outbreak of any diseases. It is envisaged that due to the implementation of the project, there would be new job creations. And as a direct positive impact, this will improve the economy of the island and the livelihood of the people. The EIA states all relevant national laws and regulations including national and Institutional regulations. The project will be implemented in full compliance with EIA regulations and Environmental laws and regulations of Maldives. Consultations were carried out with EPA. Marine research center, Island council and some members of the general public of the island. All stake holders were eager to see the project being implemented at earliest. With due consideration to environmental impact mitigation measures and adherence to monitoring program it is best to carry on the project as proposed with given recommendations of the EIA.Item Environmental impact assessment for development of 80 housing units at Goidhoo, Baa Atoll, Maldives(2011-12) Shareef, Ali; Mohamed, MiruzaThis Environment Impact Assessment is an evaluation of the potential environmental, socieconomic and natural impacts for the development of 80 housing units at Goidhoo, Baa Atoll. This EIA is prepared in order to meet the requirements of Clause 5 of the Environmental Protection and Preservation Act of the Maldives to assess the impacts of proposed development at B. Goidhoo. The primary objective of the project is part of the Government commitment to provide affordable housing to all the people of the Maldives. The total area of the development is approximately 184,800 square feets (17,168 sqm) and the size of a housing plot is 1707 square feets. Each housing unit would consist of 3‐4 bedrooms, a sitting room, dining room, 2 toilets, laundry and a small backyard and a well to provide water for domestic use. This report as considered the impacts the project could have on the environment. It is found that a major impact would be due to the waste produced during construction. However, the impact would only be for the project duration and mitigation measures for this and other impacts are also provided. Another high impact is anticipated on the social environment. If the progress of any delays could be shared with the public, this impact could be minimized. Improvement in the local economy of the island and improved livelihood are seen as positive benefits of the project.
