Abstract: | The purpose of this document is to fulfil the requirements to get necessary environmental
clearance from the Environmental Protection Agency to carry out the proposed harbour
maintenance project in Feydhoo, Shaviyani Atoll. The proponent of this project is Ministry of
Housing & Infrastructure.
The main rationale for the project is to improve the access facilities of Feydhoo Island to
facilitate improvement in the social and economic condition of the island. The island has a
harbour and but has become shallow overtime.
This project mainly involves maintenance dredging of the 63 m × 94 m harbour basin, 26m x 75
m reef entrance and disposing the dredge waste on the sides of the harbour.
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, Dredging and
Reclamation regulation and Environmental Impact Assessment Regulation 2012.
The island coastal environment has been modified due to the presence of the existing harbour.
The coral cover is in moderately healthy condition. The dominant benthic substrate of the
footprint is mainly sand and rubble.
Significant impacts of this project during construction phase of the project are the potential
impact of sedimentation on the marine water quality and consequent impact on marine life,
potential impacts on ground water and the health and safety risks to construction workers. All
these impacts can be minimized with proper mitigation measures recommended in the report
The main mitigation measures include carrying out construction activities during low tide hours
and calm weather and proper supervision of all activities by qualified personnel. The work
schedule and duration will also be planned to avoid disruptive weather conditions and complete
construction activities in the shortest time possible.
The alternatives evaluated for the project are dredging methods and dredge waste disposal sites
and alternative harbour sedimentation control measures. The “No Project” option has also been
explored and this option is not deemed preferable, given the current condition of the harbour. An
alternative sediment control measure for the operations stage has been proposed. The use of
excavator on a barge is the preferred option for alternative dredging method, since it is the most
common, practical and cost-effective method. A new site plan has been proposed given the small
volume of sand required for dredging, as identified from detailed bathymetric assessments.
This project has strong support from the island community and all site plans have been seen and
approved by the Island Council.
Monitoring plan is designed to assess any changes to the coral reef environment of the island,
coastal changes and depth variations of harbour area as well the 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.
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 on the marine
water quality, coral reef and lagoon bottom habitats. However, mitigation measures have been
proposed to adequately minimise these significant impacts |
