  6. 6. Maritime Survival Training Centre Environment Impact Assessment A. EXECUTIVE SUMMARY Maldives College of Higher Education has proposed the development project outlined below in order to establish a Maritime Survival Training Centre, especially catering requirements of courses such as personal survival techniques and proficiency in survival craft and rescue boat training. This EIA is concerned with the dredging of a small harbour (40m by 22m) and land reclamation of area 3700m3. Dredged material excavated from the harbour basin deepening works will be used as filling material during reclamation. A sea wall (breakwater) will be constructed at the western side of the harbour area. At the time of field surveys and report compilation, the bidding process was on-going; therefore the consultants are not informed of a specific time period for the development works. However, according to the proponent construction works have to be completed within 6 months. Therefore this timeframe was taken into consideration to describe the environmental conditions inherent to the project site. The projected number of workers at peak construction time is expected to be 30 labourers. Accommodation of labourers could be in rented rooms or houses at Villingili or Male’. All construction related materials can be stored in the project site once the reclamation work is completed. There are two main types of potential impacts arising from the development of the proposed project site: short term impacts during the construction phase and impacts from irreversible modifications of the site. Long term negative impacts due proposed development are few and the magnitudes of these impacts are difficult to determine due to the time available to carry out appropriate field assessments. Furthermore, no information is available of the impacts associated with coastal modification works that have been already implemented in Villingili as part of various development projects (at the moment large scale coastal modification is observed at Villingili, commercial and ferry harbour, reclamation and seawall at the southern side and coastal protection in the form of a revetment or retaining wall at the south west corner of the island). 6
  7. 7. Maritime Survival Training Centre Environment Impact Assessment The proposed site for the project appears to be suitable for the development, taking into account the environment, construction feasibility and economic values of the proposed development. No major impacts are predicted by the proposed development project. Minor impacts associated with the project are short-term (e.g. sedimentation) and due to the scale of the proposed activities and the nature of the habitat that would be impacted, the sedimentation impacts are considered insignificant. Hydrodynamics and coastal processes around the island may have already changed as a result of impacts associated with previous development works which are more significant and long-term (duration of the project) than the proposed project. Therefore, predicted coastal impacts associated with this project would be comparatively minor and insignificant. No major socio economic impacts were identified as a consequence of the project since no local people would be relocated. Furthermore, the land allocated for the project belongs to the state and there were no vegetation that may be privately owned. Despite negligible impacts associated with the project, appropriate monitoring of constructional activities will be part of the development strategy to further minimise any impacts identified. Furthermore the proposed monitoring would assist to mitigate any unforeseen impacts that may occur. 7
  8. 8. Maritime Survival Training Centre Environment Impact Assessment B. PROJECT DESCRIPTION B.1 Purpose of the report and need for the EIA This document presents the findings of an Environmental Impact Assessment (EIA) for the construction of a Maritime Survival Training Centre at K. Villingili. The centre will have a harbour (40m in length, 22m in width) for life boat and emergency evacuation training. Part of the land allocated for the project has to be reclaimed. Estimated area of reclamation is 3700m2 (volume of dredged material required, 2856m3). Development projects are required to carryout EIA studies under the Environment Protection and Preservation Act of Maldives. The developer is required to obtain approval of the Ministry of Environment, Water and Energy prior to the implementation of any development activities on the island or on the reef system. Land and Marine Environmental Resource Group Pte Ltd (consultant) have been contracted by the Maldives College of Higher Education (client), to prepare the EIA and to provide assistance in other environmental related activities of the project. This EIA is thus prepared by the consultant is in accordance with Maldives Environmental Impact Assessment guidelines, and other relevant regulations and guidelines applicable to the proposed project. B.2 Procedure of the EIA All the development projects that have a socioeconomic relevance are required to submit an environmental impact report which forms the basis for project approval. As such projects are required to follow a screening process identifying the environmental impacts associated with the project. As the regulator, MEEW based on the impacts associated with project makes a decision on the nature of the report to be submitted. An EIA shall be submitted for projects with significant impacts whereas an IEE suits for projects without significant impacts. The screening process required to submit an EIA which requires an approval of the scope of work for the report in consultation with MEEW. In accordance to the regulations of Ministry of Environment, Energy and Water, a letter was send stating to the nature of the project and likely impacts associated. The study parameters stated in the letter will be used as the TOR for the EIA as agreed by the Ministry of Environment, Energy and Water (see Annex 1 for the letter). 8
  9. 9. Maritime Survival Training Centre Environment Impact Assessment The project proponent revealed the project to the consultant before a site inspection was carried out to assess the conditions at the site and determine the potential impacts. Qualitative methods were used to determine the coastal processes and areas affected: qualitative methods to assess substrate types and cover on the areas concerned by the works, as well as downstream from this area. This study was complemented with both land and underwater photographs of the area in question. The following tasks were undertaken in carrying out the EIA study: Task 1. Description of the Proposed Project - Provide a full description of the overall project using plans, maps and graphic aids at appropriate scales. This is to include: project locations; general layout (size, capacity, etc.); land and lagoon areas selected for development, construction methodology (excavation works, wharf etc.), site management, operation and maintenance activities; plans for providing utilities, waste disposal, sewage treatment and other necessary services; and employment. Task 2. Description of the Environment - Describe the physical, ecological, demographic setting of the project. Survey and present information provides a detail assessment of the existing conditions of the site. Assemble, evaluate and present baseline data on the relevant environmental characteristics of the study area, including the following: a- Physical environment; reef line; depth measurements; seawater quality; climate and meteorology and coastal oceanography. b- Biological environment: flora and fauna of the terrestrial, coastal environment, and coral reef ecosystems around the island. Task 3. Legislative and Regulatory Considerations - Describe the pertinent environmental laws, regulations and standards governing harbour developments, environmental quality, health and safety, protection of marine and terrestrial flora and fauna, protection of endangered species, and construction of tourism facilities. 9
  10. 10. Maritime Survival Training Centre Environment Impact Assessment Task 4. Determination of Potential Impacts – Identify the major issues of environmental concern and indicate their relative importance to the design of the project. Distinguish long-term and short-term impacts, construction and post-construction phase impacts. Identify the significant impacts and those that are cumulative, unavoidable or irreversible. Task 5. Mitigation and Management of Negative Impacts – Recommend feasible and cost-effective measures to prevent or to reduce the significant negative impacts to acceptable levels. Task 6. Development of a Monitoring Plan - Prepare the outline of a plan for monitoring the impacts of the project and the implementation of mitigating measures during construction and preconstruction. Task 7. Determination of Project Alternatives – Examine alternatives to the project including the no-action option. 10
  11. 11. Maritime Survival Training Centre Environment Impact Assessment C. PROJECT DESCRIPTION C.1 Project Proponent Project proponent of the proposed project is Maldives College of Higher Education. The Maritime Survival Training Centre will be managed by the Centre for Maritime Studies. This centre is a faculty of Maldives College of Higher Education. C.2 The Project The proposed development project involves reclamation of land (2856 m3), dredging a small harbour (40m in length and 22m in width) for life boat evacuation and emergency jumping training (880 m3) and break water of 36m long and 6.9m wide will be constructed at the western side of the harbour area to protect the harbour. The Harbour area will be sheet piled. Entrance area will also be dredged to -4.5MSL. Class room and changing facilities will be built on the reclaimed land (see Annex 2 for the scaled drawings of the site, harbour and the buildings). Figure 1 Project layout (see Annex 2 for scaled drawings set) 11
  12. 12. Maritime Survival Training Centre Environment Impact Assessment C.3 Project Location The island of Villingili is located on the southern periphery of K. Atoll, in the Maldivian Island chain (Figure 5). The project site is located at the western side of the Villingili south of the commercial harbour (Figure 3). The area was previously used as a boat yard for repairing works of vessels. Part of the vessel repair yard will be reclaimed under the proposed project. Furthermore, currently allocated commercial plots temporarily allocated to fish processors and other type of processors at cottage level falls within the allocated boundary. Alternative sites both for boat repair harbour and commercial plots have been identified by the Ministry of Housing and Urban Development (see Annex 3 for the land-use plan of Villingili demarcating the allocated land for the Maritime Survival Training Centre and alternative site for commercial plots; section E5).

  13. 13. Maritime Survival Training Centre Environment Impact Assessment C.4 Need for the Project The centre of Maritime Studies conducts various types of seamanship trainings. The faculty for Maritime Studies is mandated with training seafarers to internationally required qualities and efficiency. These training programs have to comply with the requirements of IMO conventions on Standard of Training, Certification and Watchkeeping (STCW). Among the trainings, personal survival techniques and proficiency in survival craft and rescue boat training needs a water tank or pool to conduct the training with safety to trainees. For the above mentioned trainings, emergency evacuation training consists of abandoning vessels (jumping off) during a fire related or similar scenario. For this training a pool constructed inland would be considerably deep, which will have lots of maintenance problems (e.g. flushing, filtration). The easiest way would be to have a harbour like enclosure that has a depth of 4-4.5m. Since the training involves simulation of real event the participants have to jump from a tower that has similar height as a cargo or similar class vessel. Also since Maldives has signed the IMO convention, the government focal point has to provide the trainings for its international and national commercial seafarers. Shipping is a competitive and high-tech international industry; therefore it is imperative that Maldives train its seafarers to international standards to keep pace with other countries. C.5 Location and extent of site boundaries The proposed Maritime survival Training Centre will be located at the western side of the island, south of the commercial harbour close to the now abandoned vessel repair yard (Figure 2, 3). The area has already been modified over the years; the proposed site is also part of a reclaimed portion of Villingili. Project boundaries are defined by the dominant current flow (tidal currents) experienced at the area. Strong tidal currents are experienced at channels near Male’ (Gaadhoo kolu, channel between Male’ and Villingili and Channel between Villingili and Gulhifalhu). Direct impact area for the proposed project is the immediate project area, whilst the indirect impact areas are northern and southern side of the project area (Figure 4). 13

Maritime Survival Training Centre Environment Impact Assessment Figure 4 Project site boundaries, giving direct and indirect impact areas from excavation and dredging works C.6 Construction phases and schedule for implementation At the time of field surveys and report compilation, the bidding process was on-going; therefore the consultants are not informed of a specific time period for the development works. However, according to the proponent construction works have to be completed within 6 months. Therefore this timeframe was taken into consideration to describe the environmental conditions inherent to the project site. Wind, wave and current related impacts were assessed for both northeast and southwest monsoon to reflect the duration of the construction phase. Work schedules of similar dredging and excavation projects were used by the consultants to draw up a work schedule for the proposed project (harbour development at various islands in Maldives). According to the project 14
  15. 15. Maritime Survival Training Centre Environment Impact Assessment proponent they estimate 2-3 months for dredging and reclamation works. After that the sheet piling and levelling works will be done. After completion of the dredging and reclamation works, the sea wall protecting the harbour area will be constructed. After the levelling works is finished construction of davits, jumping platforms and class room facility will be initiated. Table 1 Construction schedule for the Maritime Survival Training Centre Work schedule for harbour construction No. Description 2007 February March April May June July August September October 1 Bidding 2 Mobilization 3 Excavation and dredging works 4 Sheet piling, inside and outside 5 Construction of sea wall 6 Construction of Devits and platforms Construction of class room and 7 changing facility 8 Demobilazation C.7 Major inputs - Construction materials, methods and processes At the time of this study, the bid hasn’t been awarded to a contractor yet; therefore method of excavation or dredging is not informed to the consultants. Therefore projects of similar nature were used to assess suitable methods that could be used for the proposed project. Due relatively small dredging and excavation involved in the project, most economical method would be to use excavators. One excavator will be enough to do the reclamation and dredging works. 2-3 trucks and bulldozer have to be used for levelling the ground. Sheet piling can be done either using the excavator with a hammer or crane with driving equipment. For the construction of seawall, a crane loaded on to a barge will be used. The rocks for the seawall construction will be loaded on to the barge for their deployment. Since the project location is at an inhabited island, constructing temporary accommodation isn’t required, but temporary storage shed may have to be built. Method and location of accommodating construction workforce depends on the contractor; either in Malé where the workforce can commute daily to the work site or in Villingili in rented accommodation. 15
  16. 16. Maritime Survival Training Centre Environment Impact Assessment Major input of the proposed project is reclamation of 3700m2 area of land (volume 2856m3) and dredging of a harbour 40m in length and 22m in width to a depth of -4.5m (MSL). The dredged material removed (880 m3) during harbour basin excavation will be use as filling during reclamation. At present the entrance and entrance channel of the harbour for the proposed project has depth of -2.1m (MSL) and is sandy (probably dredged during construction of the temporary vessel repair yard). Materials needed for the proposed project can be brought to the site either using the existing commercial harbour north of the site. Trucks or lorries can be used to transport the material to the site. The materials can be stored on the reclaimed land. Rocks for the sea wall can be brought to the site on a barge. Since the construction of davits, platform and class room facilities will be initiated after the reclamation and dredging works, the harbour constructed under the project can also be used for downloading the construction materials. Since the bid is not awarded to a contractor, the number of labourers to be stationed at project site has not been brought to the knowledge of the consultants. Therefore work force used in similar projects is used to estimate the number of workers used during the peak period of construction. For the reclamation and dredging works total of 10 workers could be used (including heavy machine and equipment operators), for the sea wall construction 6 workers and for the rest around 30 workers. Electricity for the construction site can be met by portable generator sets or pubic electricity grid of Villingili. In case portable generator sets are used, fuel has to be stored in barrels on land. No groundwater will be used for the construction works, since it is not recommended by the environmental consultants and project consultants. Therefore freshwater will be brought to the site on tanks (plastic tanks of volume 3000-5000liters). The sewage out lets from the toilets in the changing room will be connected to the Villingili sewerage grid. Detail drawings of the harbour, seawall, and class rooms are given in Annex 2. 16

  18. 18. Maritime Survival Training Centre Environment Impact Assessment C.8 Risks associated with the project Major risks associated with the project are damage to the marine environment due to sedimentation by excavation and construction works. Chronic impacts such as this are cumulative and long term. Coastal modification involved by this proposed project may have some impacts on the littoral movement of the island. At present significant coastal modifications have already been carried out at K. Villingili, therefore hydrodynamic and littoral impacts by this project is likely to be significantly less compared to the large scale modifications made at the northern side and southern side (e.g. commercial harbour, Ferry harbour, reclamation and seawall at southern side). Since the site is located in between two man made features, the commercial harbour at northern side and revetment wall and breakwaters at the southern side, the site is effectively between two terminal groynes trapping the sediment in between creating a small beach. Therefore impacts on sediment movement by the proposed coastal modification are likely to be minor, if any. Damage to live coral is inevitable in development projects such as these. Major impacts are likely from sedimentation and smothering of live coral and other benthic organisms (close to the harbour basin and indirect impact areas, southern and northern side of the project area). In terms of social impacts, noise pollution at the excavation and construction site will be an issue. But considering this, at present a number of construction works are underway at Villingili. Heavy vehicles operating in the area may cause public safety issues. To counter this, the project area has to be closed by a fence. 18
  19. 19. Maritime Survival Training Centre Environment Impact Assessment D. LEGAL AND ADMINISTRATIVE FRAMEWORK This section outlines the relevant international convections and environmental legislation pertaining to the development under study for the construction of Maritime Survival Training Centre at K. Villingili. D.1 Environment Protection and Preservation Act of Maldives The Environmental Protection and Preservation Act of Maldives (Law no: 4/93) is concerned with the natural environment and its resources as a national heritage that need to be protected and preserved for future generation, taking in consideration land, water resource, flora, fauna, beaches, reefs, lagoons and all the natural resources. Major components of this law include environmental impact assessments prior to developmental projects that are likely to have significant impact to the environment. It also refers to specific procedure that should be followed with regard to waste disposal, oil and poisonous substances. Furthermore, hazardous, toxic and nuclear waste cannot be disposed in territorial water of Maldives and any trans-boundary movement of such material shall obtain prior permission if it is shipped through Maldives. Under Article 5 (a) of this law, an Environmental Impact Assessment has to be submitted by the developer of a project which may have potential impacts on the environment, to the Ministry of Environment, Energy and Water (MEEW) for approval before commencement of project. The development of all new resorts is outlined as such a project in the MEEW guidelines. D.2 By Law, Cutting down, uprooting, digging out and export of trees and palms from one island to another In pursuant to law number 4/93 (Environment Protection and Preservation Act of Maldives 1993), the Ministry of Environment, Energy and Water has made a by law with the purpose of educating developers about the 19
  20. 20. Maritime Survival Training Centre Environment Impact Assessment importance of trees including best management practices for maintaining trees and provide standards fro preservation of trees in the Maldives and set down rules and regulations to be adhered to prior to commencing felling, uprooting, digging out and exporting of trees and palms from one island to another in Maldives. The by law states that the cutting down, uprooting, digging out and export of trees and palms from one island to another can only be done if it is absolutely necessary and there is no other alternative. It further states that for every tree or palm removed in the Maldives two more should be planted and grown in the island. The by law prohibits the removal of the following tree types; • The coastal vegetation growing around the islands extending to about 15 meters into the island are protected by this by law; • All the trees and palms growing in mangrove and wetlands spreading to 15 meters of land area is protected under this by law; • All the trees that are in a Government protected area; • Trees that are being protected by the Government in order to protect species of animal/organisms that live in such trees; • Trees/palms that is abnormal in structure D.3 The National Biodiversity Strategy and Action Plan 2002 The national Biodiversity Strategy and Action Plan (NBSAP) is, in many ways, an environmental protection strategy and action plan. It establishes a number of pertinent guiding principles sets three focussed goals and adopts a number of wide-ranging policies and targets. This brief review identifies those elements of the NBSAP which are essentially relevant to the present project. One guiding principle established by the NBSAP is very relevant to coastal projects in general, viz. “While socio-economic development is essential, it cannot be achieved at the cost of the environment. Ecological sustainability must be a major goal in the national development”. Likewise, the following policy statements must be borne in mind when designing coastal development projects: 20
  21. 21. Maritime Survival Training Centre Environment Impact Assessment • Restrict coastal development projects such as ports only to island that have been identified in the national/regional development plan. • Discourage dredging/excavation of small harbour basins for every inhabited island by encouraging the use of natural harbours (vilu) and by seeking alternative means, such as jetties to access the islands. • Retain a shoreline vegetation buffer zone when allocating land for new housing zones or plots and other physical development activities in the inhabited islands. • Prohibit the use of coral for building coastal protection such as seawalls and promote use of alternative materials D.4 International Maritime Organization (IMO) Convention Maldives joined International Maritime Organization of United Nations in 1967. IMO convention on Standards of Training, Certificates and Watchkeeping of Seafarers was developed in 1978. The IMO convention on Standards of Training, Certification and Watchkeeping of Seafarers entered in to full was on 1st February 1997 with the 1995 amendments which completely revised the convention. The 1978 STCW Convention was the first to establish basic requirements on training, certification and watchkeeping for seafarers on an international level. Previously the standards of training, certifications, and watchkeeping of officers and rating were established by individual governments, usually without reference to practices in other countries. As a result standards and procedures varied, even though shipping is the most international of all industries. The Convention prescribes minimum standards relating to training, certification and watchkeeping for seafarers which countries are obliged to meet or exceed. The Convention did not deal with manning levels: IMO provisions in this area are covered by a regulation in Chapter V of the International Convention for the Safety of Life at Sea (SOLAS), 1974, whose requirements are backed up by resolution A.890(21) Principles of safe manning, adopted by the IMO Assembly in 1999, as amended by 21
  22. 22. Maritime Survival Training Centre Environment Impact Assessment Resolution A.955(23) Amendments to the Principles of Safe Manning (Resolution-A.890(21)). The Articles of the convention include requirements relating to issues surrounding certification and port state control. One especially important feature of the Convention is that it applies to ships of non-party States when visiting ports of States which are Parties to the Convention. Article X requires Parties to apply the control measures to ships of all flags to the extent necessary to ensure that no more favourable treatment is given to ships entitled to fly the flag of a State which is not a Party than is given to ships entitled to fly the flag of a State that is a Party. While Article VI requires flag States to ensure that seafarers hold certificates, Article X provides an enforcement mechanism by allowing Port States to verify that seafarers serving on board hold any required certificates, and to detain a ship when certain officers are not properly certificated. The port control aspects of STCW are discussed in more detail in section 4 of this handbook, under the heading "Regulation I/4 - Control Procedures." D.4.1 International Convention on Standards of Training, Certification and Watchkeeping for Seafarers, 1978. Amendments made 1998, 2006 D.4.1.1 Emergency, occupational safety, medical care and survival functions Regulation VI/l Familiarization and basic safety training and instruction for all seafarers: The requirements in this regulation are divided into two categories. The details are specified in section A-VI/l of the STCW Code, and the required training or instruction must be provided before the seafarer concerned is assigned any shipboard duties. All seafarers (i.e., persons who are working on the ship and are not classified as passengers) must receive either (i) approved training in personal survival techniques, based on table VI/l-l; or (ii) sufficient information and instruction to be able to take steps in an emergency to respond quickly, properly and safely. A checklist of these skills is set out 22
  23. 23. Maritime Survival Training Centre Environment Impact Assessment in Section A-VI/l of the STCW Code. All seafarers who are working on the ship as part of the complement involved in manning, watchkeeping, emergency response training or instruction in four areas: personal survival; fire prevention and fire-fighting; elementary first-aid; and personal safety and social responsibilities. The standards of competence for these areas are set out in four-column tables in Section AVI/1 of the STCW Code. Seafarers subject to this training requirement must provide evidence of achieving or maintaining the standard of competence within the previous five years of being assigned shipboard duties. Except in respect of seafarers on passenger ships of over 500 gross tons on international voyages, and tankers, specific training requirements may be modified to suit a ship’s size and the length or character of its voyage. Regu1ation VI/2 - Proficiency in survival craft rescue boats and fast rescue boats: Under this regulation, a candidate for a certificate of proficiency in survival craft and rescue boats must (a) meet a minimum age requirement, (b) have approved seagoing service or a combination of approved training and seagoing service; and (c) meet the relevant standard of competence set out in Section AVI/2 of the STCW Code. A four-column table is provided in that section of the code. (This section of the code is referred to in the standard of competence in Chapters II and III, under the function of controlling the operation of the ship and care for persons on board at the operational level.) In addition to meeting the requirements described in the previous paragraph, a candidate for a certificate of proficiency in fast rescue boats must (a) attend an approved training course; and (b) meet the relevant standard of competence set out in a four-column table in Section A-VI/2 of the STCW Code. Regulation VI/3 - Training in advanced fire-fighting: Those responsible for controlling fire-fighting operations on seagoing ships must (a) complete advanced training in techniques for fire-fighting, with an emphasis on organization, tactics and command, and (b) meet the standard of competence set out in the four-column table in Section A-VI/3 of the STCW Code. Unless this training is already included as a qualification for a certificate (as it is for certain operational level certificates under Chapter II and III), the seafarer concerned is to be issued documentary evidence of having attended the training. 23
  24. 24. Maritime Survival Training Centre Environment Impact Assessment Seafarers subject to this training requirement must provide evidence of achieving or maintaining the standard of competence within the previous five years of being certificated. Regulation VI/4 - Requirements relating to medical first-aid and medical care: Those responsible for "providing" medical first-aid on seagoing ships must meet the standard of competence in medical first aid as set out in the four-column table in Section A-VI/4 of the STCW Code. This standard, which is higher than elementary first aid, must be met by officers at the operational level under Chapters II and III. The master must be able to organize and manage the provision of medical care on board under Table A-II/2. Those designated to take charge of medical care on seagoing ships must meet the standard of competence in medical care as set out in the four- column table in Section A-VI/4 of the STCW Code. Unless this training is already included as a qualification for a certificate (as it is for a management level certificates under regulation 11/2), the seafarer concerned is to be issued documentary evidence of having attended the appropriate training. Except in respect of seafarers on passenger ships of over 500 gross tons on international voyages, and tankers, specific training requirements may be modified to suit a ship’s size and the length or character of its voyage. Regu1ation VI/2 - Proficiency in survival craft rescue boats and fast rescue boats: Under this regulation, a candidate for a certificate of proficiency in survival craft and rescue boats must (a) meet a minimum age requirement, (b) have approved seagoing service or a combination of approved training and seagoing service; and (c) meet the relevant standard of competence set out in Section AVI/2 of the STCW Code.

  26. 26. Maritime Survival Training Centre Environment Impact Assessment D.4.1.2 Special training requirements for personnel on certain types of ships Regulation V/1 - Training and qualification of masters, officers and ratings on tankers: Under this regulation, certificates must be issued in respect of two levels of training for three types of tankers. Officers and ratings who are assigned specific duties and responsibilities related to cargo or cargo equipment on tankers must (a) complete an approved shore based fire-fighting course (b) receive basic safety training as required under regulation VI of Chapter VI (discussed in section 9 of this handbook); and (c) either (i) complete at least three months of approved seagoing service on tankers in order to acquire knowledge of safe operational practices; or (ii) complete an approved tanker familiarization course covering the syllabus given in section A-V/i of the STCW Code. Masters, chief mates, chief engineer officers, and second engineer officers, as well as any other person who has immediate (supervisory) responsibility for loading, discharging and care in transit or handling of cargo, must, in addition to the requirements identified in the previous paragraph, have experience on the particular type of tanker on which they serve (in other words, oil, chemical or liquefied gas tanker), and complete an approved specialized training program covering the subjects listed in section A-V/i of the STCW Code for the type of tanker concerned. Regulation V 2 - Training and qualification of masters, officers and ratings and other personnel on ro-ro passenger ships: For purposes of this regulation, the term ‘ro-ro passenger ship" is defined in regulation III as meaning a passenger ship with roll on – roll off cargo spaces or special category spaces as defined in SOLAS, as amended. Regulation V/2 only applies to masters, officers and crew serving on ro-ro passenger ships engaged on international voyages. However, flag States are obligated to determine the extent to which the requirements in the regulation should apply to personnel serving on ro-ro passenger ships engaged on domestic voyages. The regulation requires personnel on ro-ro passenger ships to have specialized training, as outlined in section A-V/2 of the STCW Code, in areas such as crowd management, operational limitations of the ship, procedures for opening and closing hull openings, special emergency 26
  27. 27. Maritime Survival Training Centre Environment Impact Assessment procedures to prevent ingress of water on vehicle decks, loading and embarkation procedures, and crisis management. Refresher training is required at least every five years. Flag States are to ensure that documentary evidence of the completed training is issued to every person found qualified under the regulation. 27
  28. 28. Maritime Survival Training Centre Environment Impact Assessment E. EXISTING ENVIRONMENT E.1 General setting - Maldives The Maldives archipelago consists of a double chain of coral atolls, 80 – 120km wide stretching 860km from latitude 7° 6’ 30” N to 0° 41’ 48” S and longitude 72° 32’ 30 E to 73° 45’ 54” E (Ministry of Construction and Public Works, 1999). The double chain of Maldivian atolls lies on the parallel submarine ridges in the central part of Indian Ocean known as Laccadive- Chagos ridge. The archipelago comprises 25 atolls (Naseer, 2004) grouped into 20 administrative units. The atolls are separated by east-west running deeper channels. The atolls vary in shape from circular and oval to elliptical. The atolls contain 1190 islands, of which only 198 are inhabited. The total reef area of Maldives is 4,493.85km2 while the total land area is 227.45km2 (Naseer, 2004). Approximately 80% of Maldivian land area is less than 1m above mean sea-level. The characteristics of reefs and coral islands of the Maldives vary considerably from north to south. The atolls to the north are broad banks discontinuously fringed by reefs with small coral islands and with numerous patch reefs and faros (the word faros is derived from the Maldivian word “faru”) in the lagoon. To the south the depth of atoll lagoon increases, faros and patch reefs are rare in the lagoon, the continuity of the atoll rim is greater and a large proportion of the perimeter of the atolls is occupied by islands (Woodroffe, 1992). The islands have shallow reef flats on their seaward side, some with shingle ramparts at the seaward limit of the reef flat. The islands and the shingle ramparts owe their origin to the deposition of shingle or coral debris during storms. A number of islands can be found on a single reef. These islands may be separated by shallow passages that run across the reef flat. The width of some of these passages could be less 100m while some passages are over few hundred meters wide. 28
  29. 29. Maritime Survival Training Centre Environment Impact Assessment E.2 Geographic Location and General Setting of K. Villingili E.2.1 Island Setting The island of Villingili lie at coordinates 73°29.1’E and 4°10.4’ N which lies on the southern periphery of North Male Atoll (Figure 5). To the west at about 1km from Villingili is Gulhifalhu, which is a round shaped faro and to the east of Villingili is the island of Male. The typical depth within North and South Male Atolls is about 45 – 50m. Vaadhoo Kandu to the south of Villingili that separates North and South Male Atoll is a relatively deep channel. This channel has an average depth of about 400m and a width of about 10Km. This channel is well known to be a rough channel during the southwest monsoon. The reef system accommodating the island of Villingili has an area of approximately 0.563 km2. The reef flat on the southern and eastern sides of the island is shallower than the northern side reef flat. The southern side reef flat is typical of an ocean ward reef flat of the islands of Maldives. The near- shore environments of Villingili are composed of coralline and other bioclastic skeletal material derived from the reef. The sediments in this environment are predominantly coral fragments, calcareous algae (Halimeda) and foraminiferans. Coral predominates in coarser fraction while the sandy fraction is mainly Halimeda and foraminifera. The major forces, which produce sediment on the reef, are storm waves and waves driven by monsoon winds. Tidal and wave driven currents play a significant role in the transport of sediment. A large area of the islands limited reef flat area has been modified to cater for the needs of the population on the island. As such almost the entire reef flat area on the northern side of the island has been dredged to create small harbours (ferry and small commercial harbour). A large area of the reef flat on the southern side of the island has also been reclaimed in association with the development of the harbour in 2003. The extent of the reclamation reaches almost up to the reef edge. The ocean-ward extent of this reclaimed land is protected with a rubble mound revetment. 29
  30. 30. Maritime Survival Training Centre Environment Impact Assessment Figure 5 Geographic location of Villingili at north Male’ atoll E.2.2 Climatology The local Maldivians divide the climate of the Maldives into four monsoon periods that are characterised by very different wind climate, rain fall. These four seasons are (Table 3) the NE monsoon (Iruvai moosun), Transitonal period from NE monsoon to SW monsoon (Hulhangu halha), SW monsoon (Hulhangu moosun) and Transtional period from SW monsoon to NE monsoon (Iruvai halha). Table 3 Summary of four seasons in Maldives Season Month December NE-Monsoon January (Iruvai moosun) February Transition Period 1 March (Hulhangu halha) April 30
  31. 31. Maritime Survival Training Centre Environment Impact Assessment May June SW-Monsoon July (Hulhangu moosunAugust September Transition Period 2 October (Iruvai halha) November Generally the SW monsoon generates westerly winds and the seas are rough and the period is wetter than the NE monsoon. The NE monsoon in the Maldives archipelago is marked by north-northeast winds (Woodroffe, 1992) which are generally lighter and the period is dryer. Storms and gales are infrequent in this part of the globe and cyclones do not reach as far south as the Maldives archipelago (Ministry of Construction and Public Works, 1999). For detail analysis of wind patterns for the four seasons daily wind data for the years 2002 and 2003 for Male have been studied. The summary of these analysis indicate the winds in the central regions of Maldives is predominantly westerly and north easterly (Figure 6). The analysis also indicates that there is almost no wind from the quadrant between East and South. Analysis of the wind data for the four seasons (Figure 6) indicate that the during NE monsoon the wind is predominantly from ENE with wind speeds reaching as high as15 – 20 knots for 8% of this period (3 months). For up to 41% of the time the wind speed reaches 10 – 15 knots. During Hulhangu halha (2 months) wind direction varies between SW – E. The predominant wind direction during this period remains between ENE and E. The maximum wind speed reached during this period is 14knots. For up to 11% of this period the wind speed reaches over 10knots. For 43% of the time the wind speed is between 5 and 10knots. During SW monsoon (5 months) the wind direction is distinctly from W and WNW. Up to 8% of this period the wind speed reaches between 15 and 20knots. For 28% of the time the wind speed reaches between 10 and 15knots. For 51% of the time the wind speed is between 5 and 10knots. During the transitional period from SW monsoon to NE monsoon (2 months) the predominant wind direction remains westerly. For up to 26% of the time wind speed reaches between 15 and 20knots, 22% of the time the wind speed is between 10 and 15knots, 48% of the time the wind speed reaches between 5 and 10knots. These results have been confirmed by Kench and Brander, 2005 to be consistent with the mean long term trend in the wind climate in the central region of the Maldives. 31

A tide station at Male International Airport has continuous records of tide for over the past 30 years. The maximum tidal range recorded at this tide station is 1.20m. The highest astronomical tide level is +0.64m (MSL) and the lowest astronomical tide level is -0.56m (MSL) (Table 4). Due to close proximity of the permanent tide station at Male International Airport (Hulhule) it was assumed that the tidal signal at Hulhule will be the same as that at Villingili. Therefore the tidal datum for Hulhule applied at Villingili. Table 4 Table summarizing tide levels at Hulhule Island, Male Atoll.

Maritime Survival Training Centre Environment Impact Assessment Figure 8 Spectral density graph for the tidal records presented in figure 7 E.2.2.2 Waves Information on the swells around Maldives is limited, but there have been a few studies carried out around Male and Fuahmulah (southern region of Maldives). Wave data for Male that were recorded for the period between June 1988 and January 1990 revealed that the maximum significant wave height (Hs) recorded for the month of June 1989 was 1.23m with a mean period (Tm) of 7.53s. For the month of July 1989 maximum recorded Hs was 1.51m and the corresponding Tm was 7.74s. In June and July 1989 mean wave periods were 5.0 – 9.0s and the peak wave periods within 8.0 – 13.0s. Wave data for the period between September 1988 and July 1989 shows a probability of exceedance of Hs = 1.0 m was approximately 0.1 and of Hs = 1.5 m was approximately 0.0015 based on the wave data of period September 1988 to July 1989. JICA, (1992) reported that the wave climate in Male region is generally higher in the months of June, July and August with a predominant wave direction of S (180o). During October-December the waves have a shorter period with wave directions varying from S and W (180o -270o) (Figure 9). 34
  35. 35. Maritime Survival Training Centre Environment Impact Assessment Figure 9 Graphs showing the significant wave height and wave directions in the southern region of Maldives (source: DHI, 1999) According to DHI, (1999) the significant wave height (Hs) in the southern regions of Maldives exceeds 3m in about 0.1percent of the time (Figure 10). Figure 5 also shows that the highest waves are from W and S. From NW, N, NE and E, significant wave height exceeds 1m in less than about one per cent of the time.

  36. 36. Maritime Survival Training Centre Environment Impact Assessment Deepwater wave information for the region obtained from global wave climate data indicates that the dominant swell approaches Maldivian archipelago from southerly quarters (Young 1999) (Figure 10). On a seasonal basis, swell is from the south-southwest from March to October with a peak significant wave height (Hs) of 1.8 m in July, and from the southeast from November to February with a minimum mean Hs of 0.75 m in March. During the field visit, monsoonal wind generated waves were experienced at the western side of the island. Wind direction during field surveys was north eastern direction. Since the commercial harbour is located at the northern side, the project area is considerably sheltered. Since the weather was calm during the field visit, wave action at Vaadhoo channel was low. During the south west monsoon, wind direct will be from south west to west. The presence of large ring reef, Gulhi falhu protects the western side of Villingili. But during rough weather swell induced waves break off at the south western corner of Villingili reef. During the south west monsoon the project site will be sheltered. Diffracted waves hitting the southern corner of Villingili channel may create circular currents at the southern side of the Villingili channel (see figure 12 for general wave direction for K. Villingili). 36

  40. 40. Maritime Survival Training Centre Environment Impact Assessment Current measurements at the western side and southern side of the island, using a drogue that was tracked with a DGPS system provided limited information on the current pattern at the project location (figure 13). These data indicated that the current at the project location is driven by the wind generated waves and tidal currents flowing through the Villingili channel and Vaadhoo channel. At the time of drogue tracking exercise the tidal current was flowing out of the atoll lagoon. This is recorded by the tracks, during a mid tide, as a slow mowing current at a maximum speed of 0.17m/s. But at the central area of the channel, currents created by waves at the Vaadhoo channel breaking at the south eastern corner of Gulhi falhu, creates a wirl pool current (area where both currents meet). Current measurements taken at the Vaadhoo channel close to the Villingili channel entrance recorded currents speed at a maximum 0.57m/s. Waves converging to shallow reef slope area creates a current at slow speed of 0.29m/s. This current then moves into the channel, where it meets the current generated by the wind waves and tide flux. E.3 Beach Environment Significant alterations and modifications have been made to the Villingili shoreline over the past several years. Among the modifications, the ferry terminal at the north eastern side of the island, Commercial harbour at northern western side of the island, reclamation and seawall at southern side have significantly impacted the beach environment of Villingili. A somewhat modified stretch of beach (partly replenished beach suing sediments from a previous reclamation project) in the proximity of the project is at the northern south of the commercial harbour. This beach is relatively stable in the area because; the commercial harbour wall and vessel repair yard acts as two terminal groynes trapping the sediments with little change to the shoreline due to alternating monsoons. During the north east monsoon the beach accumulates at the vessel harbour/boat repair area. During south west monsoon the beach accumulates at the commercial harbour area (figure 14, 15). At the time this survey (north east monsoon) the beach is accumulated at vessel harbour/boat repair end. The sediment movement at the southern side of Villingili is also obstructed trapped in between two man-made coastal structures. The revetment wall of waste management area and the coastal protection constructed at the south 40
  41. 41. Maritime Survival Training Centre Environment Impact Assessment eastern side (granite rock composed break water). During north east monsoon sediment accumulates at the waste management site area, whilst during the south west monsoon this sand is transported to the reclaimed bay like area at the southern side (see annex 3 to identify various locations). At present a natural beach is formed on the eastern side of the island in between the projection of the shoreline extending east and the expanded ferry harbour somewhat creating a bay. The beach here is likely to alternate to in response to monsoonal winds and near-shore currents. In short, due to the coastal modifications that exist around the island with several terminal groynes there is very little room for beach sediments to move around the island and the extent of beach movement is determined by these coastal structures.

  42. 42. Maritime Survival Training Centre Environment Impact Assessment E.4 Marine Environment E.4.1 Introduction This EIA report presents the environmental impacts associated with the construction of Maritime Survival Training Centre at K. Villingili (western side of the island). Impacts associated with such projects maybe multiple and cumulative, and in some cases can lead to significant damages to the environment. Purpose of this survey is to describe the current status of the environment and also to establish a baseline for monitoring possible impacts related to the project on major marine habitats. E.4.2 Methodology In order to assess the status of the marine environment in the vicinity of the proposed project location was surveyed. Documenting the status of the reef benthic community prior to start of construction works of the project was considered as a major component of the marine environment that could be used to monitor impacts to the marine environment especially due to the project construction and operation activities. The reef benthic community in the vicinity of the project site were studied using standard marine survey methodologies. These include photographic quadrat survey method for the assessment of reef benthic community and the visual census methodology for the assessment of the fish community. One square meter frame was used along a fixed transect line in the vicinity of the proposed development area, photographs taken every meter along a 20 meter transect line. Same transect line was used as the basis for the fish survey to assess the abundance and diversity of reef fish at the time of the survey. The locations of the reef surveys are given in Figure 16. These survey methods are widely practiced in coral reef ecological surveys in many coral reef areas of the world and the methodology is described in survey manual for tropical marine studies (English et al., 1997). 42

  44. 44. Maritime Survival Training Centre Environment Impact Assessment E.4.3 Results and discussion E.4.3.1 Reef benthos The reef comprising Villingli is an atoll rim ring reef on the south-western end of North Male atoll (figure 5). This reef is separated from the other reefs by two channels on its west and east. On the east is the Villingili channel between Male and Villingili and on the west is Gulheefalhu (ring reef) separated by a narrow channel. Reef morphology here is characteristic of typical atoll out side reefs with poorly developed spur and groove formation at wave break zone. On the north side the reef is characterized by a typical atoll inner reef. With two channels on either side of the reef, the reef complex of Villingili is surrounded by a diversity of habitats. Villingili has a history of various types of developments. Prior to 1970s the island was used as a jail, subsequently developed as a tourist resort until early 1980s until it was decided to develop to meet the housing demand for Male’. As such, the existing urbanization started in 1980s and slowly became a dense population centre next to Male’. Along this development include the requirement for various infrastructures, which include expansion of the old harbour, waste disposal and collection centre. The land required for this infrastructure development was reclaimed by material dredged from the shallow lagoon. As such the land reclaimed and developed on the shallow reef flat added to the landmass and the reclamation extended to the reef edge from north and west side of the island exhausting the extend of reclamation. Because of this reclamation the outer reef flat and reef slope has been considerably modified. This ecological study is an attempt to describe the existing marine environmental condition at the proposed project site. It has been recognized that the proposed project implementation would have little impact on ecological functioning of the reef. It is evident that significant environmental impact has already resulted through various coastal development activities over the past several decades. These include Villingili ferry terminal, Villingili harbour, reclamation works on the southern side of Villingili and reclamation works associated with waste disposal site of Villingili on the western shoreline. These activities have directly resulted in substantial change not only to the 43
  45. 45. Maritime Survival Training Centre Environment Impact Assessment coastal hydrodynamics but also adjoining coastal habitats almost exclusively to the coral reefs. It is also evident that some modification has been resulted to the reef ecosystem in the vicinity. Live coral cover was relatively low for all surveyed sites (figure 17). Coral cover ranged from very low 5% to 8% between the sites surveyed at the proposed reclamation area and the vicinity around 2 to 3 meter depth. Over 40% of the reef substrate consisted of coral rock, rubble and sand. Turf algae covered approximately 40% of the reef substrate covering the dead corals and reef pavement. These rubbles have originated from dead branching corals that may have been part of the coral community in these locations. 45 40 35 30 % cover 25 20 15 10 5 0 Turf algae Macro algae Rock Rubble Sand Soft coral Coralline algae Others Live coral Ascidians Figure 17 Reef substrate in the vicinity if the proposed development site. 95% confidence interval for each category is shown. n=3 Coral species diversity was low for all the surveyed transects and was similar to both sites and depths surveyed (figure 18). Branching coral species (mainly Acropora sp) were few but recorded from all transects. Recently settled corals are not common in the survey area. The presence of adult colonies in the area indicates that it potentially would be the source of larvae as new coral settlement. However, in the presence of environmental stress such as sedimentation, mortality of newly settled corals would be high. Smothering of newly settled corals and its death would therefore be high on horizontal surfaces compared to vertical surfaces. Massive types of corals such as poritids 44
  46. 46. Maritime Survival Training Centre Environment Impact Assessment and several species of Faviids (Favia, Favites, Pavona and Leptoria) are present among the live coral cover. The dominant coral genera were Porites (76%) and 5 genera of the family Faviidae accounting to 19%. Pavona was low in abundance (2%). In general coral of massive growth forms are dominant corals among the coral community. Pocillopora (mainly Pocillopora verrrucosa) accounted for less than 2% of the live coral cover (figure 18). Favia 4% Favites 5% Leptoria 6% Pavona 2% Hydnophora 2% Platygyra 2% Porites 76% Pocillopora 1% Others 2% Figure 18 Generic composition of the live coral community Previous studies at Villingili reported similar results on reef benthos. Direct comparison of the can be made on live coral cover reported at the same site as part of an environmental evaluation for a reclamation project by Ministry of Housing and Urban Development (Environmental Evaluation for the Proposed Reclamation and Coastal Protection Works at Villingili, Male atoll, 2006). Live coral cover reported from this site ranged from 2 to 8% with an average cover of 5% from 4 transects. This is in agreement with the coral cover estimated from this study. 45
  47. 47. Maritime Survival Training Centre Environment Impact Assessment Figure 19 Porites lobata colony observed at the southern western side of the reef (left), three species of butterfly fish was observed at survey sites, two species of butterfly as seen in this picture, Hemiturichthys zoster and Chaetodon melannotus Similarly, a large-scale survey around the reef system of Villingili conducted in 1998 as part of ecological assessment of Villingili harbour development project. Live coral cover for the outer reef stations reported from this study varied from 12-27%. Coral cover in the atoll channel (close to this project site) was reported higher (20%) in the reef slope compared to the corresponding reef flat stations. Live coral cover then (1998 study) at approximately same location of the present study reported approximately 7- 15%. Comparable figures to reef health to the previous estimations were also reported in 1988 in Villingili Development Plan, a report prepared by United Nations Centre for Human Settlement in 1988 (UNCHS/project MDV 88/006). Based on this information and the results of the present study it can be concluded that the reef environment around Villingili has experienced some inevitable damage to the reef as result of the reclamation and show a declining trend in coral cover over the past few decades. Large part of reef flat of Villingili has been reclaimed very close to the reef edge for various coastal development projects consequently leading to the current status of the reef. In addition to these coastal development projects, natural causes may also have contributed to degradation of the reef. Among these, the most significant damage to the reefs has been caused by coral bleaching event which severely affected the reefs in Maldives. Live coral cover in shallow reef areas around Maldives was reduced from 40-60% (average value for a healthy reef) to less than 5%. In addition there is significant evidence that the reefs are compounded with solid waste either direct disposal to the reef or spill over during the transport of waste to Thilafushi. It also noteworthy to mention that prior to the current waste management practice the waste generated from 46
  48. 48. Maritime Survival Training Centre Environment Impact Assessment Villingili was disposed as a landfill in Villingili. This has lead to substantial level of solid waste pollution on the reef environment. There are no studies on impact of pollution specific to this site to substantiate whether the current reef status resulted from waste disposal on to the reef. However it is likely that harmful leachates from the waste may be a significant factor influencing to the current deteriorated state of the reef, especially due to the proximity of the waste disposal site to the shoreline. Figure 20 Effects of shore-based fishing and mis-management of solid waste; dense mesh of monofilament line from high intensity shore based fishing (left) and fish waste disposed to the reef from a nearby semi industrial fish processing household. E.4.3.2 Reef fish community Fish census surveys showed similar trends in terms of abundance of fish at the two sites surveyed. Between 35 species of fishes belonging to 11 groups of fish were recorded (Table 5, 6). Schools of damselfishes, surgeon-fishes and fusilier form school within the study area. The densities of fish grouped as families are given in (Table 5, 6). Butterfly fishes and parrot-fishes are good in species diversity despite the low live coral cover. The reef slope is characterized by relatively high topographic relief which may have been the reason for the diversity and abundance of fish species (figure 21). Commercially valuable food fishes such as jacks and snappers are also recorded here though not in abundance. Fusiliers, a popular baitfish species are also observed schooling in the vicinity. 47
