Third addendum to the environmental impact assessment for the proposed Hulhulé-Malé bridge project
(2016-05) CDE Consulting
The purpose of this document is to assess the potential environmental impacts and mitigation measures for the proposed changes to the Hulhulé-Malé Bridge project. This document is an addendum to the original Environmental Impact Assessment (EIA) prepared for the Bridge project in November 2015. The proponent of this project is Ministry of Housing and Infrastructure. The addendum is prepared to address the need to use Gulhifalhu NE reef flat to temporarily store large steel structures (Steel Pipe Piles, and Steel Casings) of the bridge. The main rationale for selecting this lagoon is the short distance to the project site, availability of space, access to deep water and relatively calms sea conditions to safely store the structures. The pipes will be removed in 7-8 months. The main reason why the piles have to be stored is due to the difficulties in holding a chartered barge for a 7 month period to store the pipes. The study area of this project considers the proposed storage site in Gulhifalhu Lagoon and surrounding areas that are likely to be affected by the proposed changes. The site has been affected by past reclamation activities and human activities. The site is also earmarked for future reclamation. The proposed developments are generally in conformance to the laws and regulations of the Maldives. The key impacts from the proposed changes are on the marine water quality, marine biodiversity within the pipeline footprint, and health and safety risks to workers. A number of mitigation measures are proposed for the most significant impacts from the project. These include ensuring only licensed, well-qualified and experienced personnel operate vessels and machineries; undertaking unloading and loading works in calm sea conditions; ensuring strict health and safety measures are followed at site; and to place the pipe fully and perpendicular to the reef flat. Alternative site was assessed to store the steel structures, at Thilafushi Reef Flat, Hulhumale Reef flat and Hulhule reef. The Hulhumale’ site is not suitable due to flight path restrictions and proximity to resorts. Hulhule site does not have enough space and there is too much marine activity in the area. Thilafushi site is suitable but when compared to Gulhifalhu site the distance to bridge site is longer and is more exposed to SW monsoon conditions. All sites have similar environmental impacts. Thus, the proposed Gulhifalhu site was preferred. Gulhifalhu Investment Limited (GIL) and Environmental Protection Agency (EPA) were they key stakeholders consulted for this addendum. The key recommendations from GIL were to take all practical measures to avoid and minimize damage to the reef, and to ensure that the pipes do not block the entrance channel to Gulhifalhu located on the eastern side of the reef. The main recommendations by EPA were to plan all works according to approved EIA and addendums. If any additional components are required to properly follow the EIA procedure. All works conducted outside the scope of the approved EIA reports must be presented as an audit in this addendum. EPA also recommended assessment of Hulhulé site as an alternative for storage of the proposed steel structures. This report is prepared in accordance to the technical guidelines and EIA regulations, prepared by the Environmental Protection Agency (EPA), and the terms of reference issued by the EPA for this EIA addendum.

Environmental impact assessment for the proposed water supply system in Vilufushi, Thaa Atoll
(2016-07) CDE Consulting
The purpose of this document is to fulfil the requirements to get necessary environmental clearance from the Environmental Protection Agency to install the proposed Water Production Supply System at Vilufushi, Thaa. Atoll. The proponent of this project is Ministry of Environment and Energy. The main rationale for the project is to improve the health condition and quality of life of residents of Th.Vilufushi by establishing a proper potable water supply system that will provide clean and safe water for the residents of Vilufushi. The project is intended at providing an integrated water supply system covering rainwater and desalinated water production and supply. The proposed project involves installation and establishment of two 6,500 litres/hour reverse osmosis plant systems that consist of construction of tube well to supply raw water for the RO plants, construction of elevated water storage tanks, construction of brine discharge outfall and house connections. Furthermore, the project aims at laying of separate pipe networks for water distribution, rainwater collection and rainwater treatment system. Duration of the project is approximately 18 months. Currently the island population sources water from shallow wells constructed at individual households or in public areas. This is supplemented by collection of rainwater. These methods provide inadequate quantity and unacceptable quality due to the over abstraction and the unreliability of rainwater harvesting. All project activities will be in conformance to the laws and regulations of the Maldives, and relevant international conventions that Maldives is party to. The key laws and regulations applicable to this project are: Environmental Protection and Preservation Act, Environmental Impact Assessment Regulation 2012, Desalination Systems Regulations, and Waste Management Regulation 2013. The existing condition of the island and the proposed RO plant site was assessed for this report. Assessments conducted include marine assessments at the proposed brine outfall and alternative outfall locations. Groundwater quality and baseline noise level measurements were also taken. The assessments showed that there is no marine protected or environmentally sensitive site in the area and locations proposed for brine outfall showed mostly dead rock and rubble. The assessment shows that the RO systems can be developed on the island with limited implications on the environment. The assessment shows that the proposed developments involve significant impacts on the marine environment due to brine outfall construction, brine discharge, ground excavation and operation of vehicles and machinery. The project also involves moderately significant health and safety risks due to equipment handling and pollution. However, the predicted impacts can be minimized considerably with the proposed mitigation measures. Significant impacts of operation stage include marine degradation due to brine discharge, increased GHG emissions due to RO plant and operation of pumps stations, and increased cost of living due to additional cost in purchasing water. The assessment shows that the proposed project has many positive impacts including improved quality and accessibility to potable water, protection of groundwater aquifer, reduction of water related disaster risk, and increased employment and business opportunities The alternatives evaluated for the project is the alternative brine outfall location. The “No Project” option has also been explored and this option is not deemed preferable, given the current condition of portable water. An alternative site for brine outfall on the southwest corner was also explored against the present option and the alternative option was recommended. Monitoring plan is designed to assess any changes to the coral reef environment of the island, ground and marine water quality as these are the key areas that will be impacted from this project. Monitoring costs is estimated at USD 5,000 per annum. The management plan for this project is designed to produce a framework for anticipated impacts, including practicable and achievable performance requirements and systems for monitoring, reporting and implementing corrective actions. In addition provide evidence of compliance to legislation, policies, guidelines and requirements of relevant authorities. Stakeholder consultations were held with Vilufushi Island council, FENAKA, Vilufushi public and Ministry of Housing and Infrastructure. A willingness-to-pay survey was also conducted during field assessments. Both Vilufushi Island Council and public highlighted the need for a potable water supply system on the island. Vilufushi public is also willing to pay for the service. Ministry of Housing and Infrastructure stated they have laid duct lines to facilitate pipeline installations. Since the roads are already sealed with asphalt the public and the Council would like to see the road resealed to the original state of the road. In conclusion, this project has been designed in conformance to the relevant laws and regulations of Maldives but requires final approval from EPA for the detailed drawings. The most significant impacts are expected to be short-term impacts for the construction phase. Operational stage impacts are mainly limited to brine outfall location and emission due to power generation. However, mitigation measures have been proposed to adequately minimise these significant impacts. Overall, the project will have positive impacts to the island community of Vilufushi.

(2016-06) CDE Consulting
The purpose of this document is to fulfil the requirements to get necessary environmental clearance from the Environmental Protection Agency to establish the proposed Water Supply System at Fonadhoo, Laamu Atoll. The proponent of this project is Ministry of Environment and Energy (MEE). Project contractor is Sierra Construction Private Limited. The main rationale for the project is to enhance the quality of services and quality of life of residents of L. Fonadhoo by establishing a proper potable water supply system that will provide clean and safe water for the residents of L.Fonadhoo. The project is intended at providing an integrated water supply system covering rainwater and desalinated water production and supply. The project is expected to be completed in 12 months. The proposed project involves installation and establishment of two 150cbm/day reverse osmosis plant systems, construction of two boreholes to supply water for the RO plants, construction of RO plant building, construction of water storage tanks, construction of brine discharge outfall, preparation of catchment areas, establishment of water treatment systems, laying of pipe networks for water distribution and rainwater collection, and household connections. Currently the island population sources water from shallow wells constructed in individual households or in public areas (e.g. a mosque). This is supplemented by collection of rainwater. These methods provide inadequate quantity and unacceptable quality due to the over abstraction, pollution from the existing sewage disposal system of septic tanks and the unreliability of rainwater harvesting. All project activities will be in conformance to the laws and regulations of the Maldives, and relevant international conventions that Maldives is party to. The key laws and regulations applicable to this project are: Environmental Protection and Preservation Act, Environmental Impact Assessment Regulation 2012, Desalination Systems Regulations, and Waste Management Regulation 2013. The proposed location for RO plant is a reclaimed area with ground cover species such as grasses and few shrubs. No trees of significant importance are required to be removed for this project. Marine surveys conducted at the proposed brine outfall location showed that the area is made up of a thick sea grass bed. No coral colonies were observed within this area. Current flow on the western lagoon, where brine outfall is proposed to be located, is expected to be low for most part of the year. This may lead to flushing issues during some periods of the year. The assessment shows that the RO systems can be developed on the island with limited implications on the environment. The assessment shows that the proposed developments involve significant impacts on the marine environment and terrestrial environment due to brine outfall construction, brine discharge, ground excavation and operation of vehicles and machinery. The project also involves moderately significant health and safety risks due to equipment handling and pollution. However, the predicted impacts can be minimized considerably with the proposed mitigation measures. Significant impacts of operation stage include marine degradation due to brine discharge, increased GHG emissions due to RO plant and operation of pumps stations, and increased cost of living due to additional cost in purchasing water. The assessment shows that the proposed project has many positive impacts including improved quality and accessibility to potable water, protection of groundwater aquifer, reduction of water related disaster risk, and increased employment and business opportunities The alternatives evaluated for the project are „No Project‟ alternative and alternative brine outfall locations. The “No Project” option is not deemed preferable, given the disadvantages of existing situation of potable water in the island. Two alternative sites were explored as brine outfall locations, both in the same location as the proposed outfall location but with different lengths; (i) outfall pipe 700m from the site and (ii) 350m from the site. Alternative option 2 is preferred. Monitoring plan is designed to assess any changes to the coral reef environment of the island, terrestrial environment, the ground and marine water quality, as these are the key areas that will be impacted from this project. The management plan for this project is designed to produce a framework for anticipated impacts, including practicable and achievable performance requirements and systems for monitoring, reporting and implementing corrective actions. In addition provide evidence of compliance to legislation, policies, guidelines and requirements of relevant authorities. Stakeholder consultations for this EIA were conducted with Fonadhoo Island Council, Fonadhoo Utility and Telecommunications providers, public of Fonadhoo, and National Centre for Information Technology (NCIT). In general, all stakeholders consulted were supportive of the proposed project. The island council and public expressed strong expectations from the project. In conclusion, this project has been designed in conformance to the relevant laws and regulations of Maldives. The most significant impacts are expected to be short-term impacts for the construction phase. Operational stage impacts are mainly limited to brine out fall location and emission due to power generation. However, mitigation measures have been proposed to adequately minimise these significant impacts.

The proposed project involves installation and establishment of two 220 cbm/day reverse osmosis plant systems, construction of two boreholes to supply water for the RO plants, construction of RO plant building, construction of water storage tanks, construction of brine discharge outfall, preparation of catchment areas, establishment of water treatment systems, laying of pipe networks for water distribution and rainwater collection, and household connections. Currently the main sources of water in the island are shallow wells constructed in individual households or in public areas (e.g. a mosque). This is supplemented by collection of rainwater. These methods provide inadequate quantity and unacceptable quality due to the over abstraction, pollution from past sewage disposal system of septic tanks and the unreliability of rainwater harvesting. A reverse osmosis desalination plant of capacity 10 ton is in operation, but the production capacity of this plant is not sufficient to meet the public water demand. All project activities will be in conformance to the laws and regulations of the Maldives, and relevant international conventions that Maldives is party to. The key laws and regulations applicable to this project are: Environmental Protection and Preservation Act, Environmental Impact Assessment Regulation 2012, Desalination Systems Regulations, and Waste Management Regulation 2013. The proposed site is located on the northern side of the island just within the old vegetation line.

Environmental impact assessment for the proposed coconut palm relocation project in Maalhos, Baa Atoll
(2016-01) CDE Consulting
This Environmental Impact Assessment (EIA) is an evaluation of the potential environmental, socio-economic and natural impacts of the proposed coconut palm relocation from Maalhos to Dhigufaru Resort of Baa Atoll. Dhigufaru is a resort under construction and is scheduled to open this year. The proponent of this project is Dhigufaru Investments Pvt Ltd, and they are in the final stages of landscaping. Maalhos Island contacted the proponent to assist in clearing the land for a futsal pitch. Given that the Dhigufaru Island is looking to rejuvenate its vegetation, the proponent has contracted construction companies specializing in tree transplantation to clear the requested land and supply coconut palms required for Dhigufaru Island landscaping. The proponent has sought permission from the island council to relocate 250 palm trees to Dhigufaru Island. The proponent considered the project given the close proximity of Maalhos and the opportunity to provide service to the community. The project is aimed for the clearance of approximately 16,500 ft2 of land for the development of a futsal pitch. Major components of the project include, site preparation and mobilization, vegetation clearance, transportation to Dhigufaru, replanting, dredging the North-western side lagoon to obtain backfilling sand and levelling the site after backfilling. The project is scheduled to be completed within five to six weeks of initiation while all components at Maalhos is to be completed within four weeks. The following Laws and Regulations of Maldives and International Conventions will be strictly adhered during the implementation of the project. The key laws and regulations of the Maldives to which the proposal is applicable are: − Environmental Protection Act, − Environmental Impact Assessment Regulations 2012, − Regulation on Cutting Down, Uprooting, Digging Out and Export of Trees and Palms from One Island to Another − Dredging and Reclamation regulation − Regulation on preservation of old trees − Other relevant international and national conventions ‘No project’ option is evaluated for advantages and disadvantages. Alternative project site (island) is not considered as this cannot be changed. In addition, an alternative tree felling method has been assessed. The potential significant impacts from the project on the natural environment are: − Groundwater and marine water contamination due to chemical (vehicle fluids) leak and from dredging process. − Pollution due to waste including green waste − Marine water pollution during transportation of materials and removal of waste − Impact on marine life due to dredging activities − Changes to island coastal environment due to creation of sediment sink Potential positive socioeconomic impacts are: − Paves way for further development with new recreational facilities − Dhigufaru Island could be completed and open for business at earliest creating job opportunities for locals − Guest satisfaction improved Monitoring program is based on the information requirements of the project. The key areas highlighted in the program are: − Groundwater quality and Marine water quality for indication of contamination by chemicals and/or dredging − Management of waste in particular hazardous waste and inappropriate disposal − Coastal changes and depth of the dredge area − Maintaining logs to monitor replanting quantities and targets are met. The proponent is committed to undertake the monitoring programme. The project poses some negative environmental impacts. However with proper caution and implementation of the given mitigation measures the project could offset the negative impacts and could be implemented smoothly. Overall, the project aims to reuse vegetation to rejuvenate the vegetation system in Dhigufaruvinagandu, which would be given utmost care due to their value for the resort island. These are trees that may otherwise be discarded. In conclusion, project mainly has beneficial impacts to both the locals of Baa Maalhos and the management of Dhigufaru Resort.
Technical Report
First addendum to the environment impact assessment prepared for the proposed development of 7,000 social housing units at Hulhumale’ phase II
(2016-12) CDE Consulting
The purpose of this document is to fulfil the requirements to get necessary environmental clearance from the Environmental Protection Agency to construct a temporary jetty at Hulhumale’ phase II. This jetty is required for the transportation of construction goods, equipment and machineries for the development of 7,000 social housing units at Hulhumale’ Phase II. EPA has approved the original EIA for the proposed development of social housing units on 22 September 2016. This addendum is required for the construction of the jetty. The proponent of this project is China State Construction Engineering Limited (CSCEC). The rationale for the proposed construction of the jetty is to facilitate the transportation of the construction goods and machineries to the project site. The project to develop 7,000 social housing units requires large-scale machineries, equipment and high quantities of construction materials, which will need to transported in bulk to the project site. Hence, the proponent has decided to construct a temporary jetty, which will have the capacity to moor a 5,000DWT vessel. The contractor for this project is CSCEC Limited and it is financed through bank loans. For the purpose of this project, HDC has allocated an area of 3,204.20 sqm for temporary loading and unloading of materials towards the western side of Hulhumale’ Phase II. HDC has also given permission to the proponent for the construction of the jetty. The project proposes to construct a jetty that will be divided into two parts. The first part will be allocated for wharf operation area (40 m wide) and the other part for temporary transfer stacking yard. The project will involve excavation to a depth of 3 m. During this process, 1,385 m3 of sand will be dredged that will be used for backfilling at the end of the jetty. The surface of the jetty will be backfilled with sand and the sides will be protected using sand bags. In addition, 30 cm thick packaged concrete will be laid as toe protection for the foundation bed. Project duration is estimated to be 2 months. The key laws and regulations applicable to this project are: Environmental Protection and Preservation Act, Environmental Impact Assessment Regulation 2012, sand and coral mining regulation and Dredging and Reclamation Regulation. In addition, this project requires approval from HDC. The existing environment of the project was assessed for the purpose of this addendum. Assessments conducted include marine water quality and marine assessment. Marine assessment showed that no significant fish life or coral colonies occur at the site. The area is mostly made up of a sandy bottom covered in thick patches of algae. Marine water quality assessment showed that water is turbid. Significant impacts of this project during construction phase of the project are the potential impact of greenhouse gas emissions, marine water turbidity during dredging and impact on groundwater and soil condition due to oil spillages and accidental leakages. There are cumulative impacts on the site due to recent extensive land reclamation in the area. The reef, water quality and shoreline has already been extensive modified. The main mitigation measures include carrying out construction activities during low tide hours and calm weather, carrying out the work in the shortest time frame possible. Mitigation measures also include, storing oil and chemicals in sealed containers, and training workers in spill prevention and cleanup, and designate responsible individuals. The “No Project” option was explored for this project. However given the importance of this project for the overall project, the plan is to go ahead with the project. The monitoring plan is designed to assess impacts to the marine environment and impacts to groundwater quality. The cost of monitoring is estimated to be between USD 1,000 and USD 2,000 per annum. The management plan for this project has been updated to include the key management requirements during construction of jetty. Stakeholders consulted for this project include, Environmental Protection Agency and Housing Development Corporation. EPA advised to undertake appropriate mitigation measures to prevent sedimentation. HDC emphasised to not use the temporary area given for the project for storing materials. They also advised to keep the vessels moving in the area to avoid traffic since the area has other jetties in operation. Both stakeholders highlighted that the jetty must be demobilized once the overall project is complete. The main conclusion of this report is to proceed with the project but after incorporating the mitigation measures proposed in this addendum. Safety during construction must be a priority.
