for Environmental Impact Assessment Study for Designation of New Fish Culture
Zones Environmental Impact Assessment (EIA) Report for Establishment of Fish
Culture Zone at Mirs Bay November
2022 |
Marine fish culture has been an important activity for fisheries
production in Hong Kong over decades. Mariculture activities are required to
operate under licence in designated Fish Culture Zones (FCZs) under the Marine Fish Culture Ordinance (MFCO) (Cap.
353). In view of the environmental
impact resulting from mariculture, there has been a moratorium on the issue of
new marine fish culture licences (MFCLs) and licensed raft area extensions in
the existing FCZs since 1990, as well as on the designation of new FCZs, except
for a limited number of forced re-siting necessitated by public works. Given the technical advancement in mariculture
techniques and strengthening of regulatory measures, together with the changes
in the operation of the sector over the years, the environment of FCZs and
marine environment in the vicinity have improved significantly in the past two
decades.
In
2010, the Committee on Sustainable Fisheries (CSF), which was established by
the Government to study the long-term goals, direction and feasible options for
the sustainable development of local fisheries industry, recommended a review of the moratorium to facilitate fishermen to switch from
capture fisheries to mariculture.
Mariculture is considered a practical alternative for capture fishermen
to make a living as their knowledge on marine environment and fish would be
useful in farming marine fish.
To pave the way for facilitating the sustainable development of the
local mariculture sector, the Agriculture, Fisheries and Conservation Department
(AFCD) proposed to lift the moratorium by designating new FCZs and issuing new
MFCLs. In 2014, the AFCD commissioned a
consultancy study to explore suitable sites as new FCZs on the basis of a list of social
and environmental criteria with reference to the latest international fish culture
practices ([1]).
Relevant stakeholders, including Government bureaux / departments and
mariculture representatives, have been consulted to gauge their views on site
selection. The mariculture sector in
general supported the designation of new FCZs and agreed that the sector should
be modernised. Four locations have been
shortlisted as potential sites for the designation of new FCZs, including Wong
Chuk Kok Hoi FCZ, Outer Tap Mun FCZ, Mirs Bay FCZ and Po Toi (Southeast)
FCZ. The Chief Executive announced in
the 2018 Policy Address that the Government would recommend designating new
FCZs at suitable locations, which would create room for the mariculture sector
to grow further, including allowing capture fishermen to switch to this
sustainable mode of operation, making it possible for the development of newer
type of deep-water mariculture in the open sea, and attracting new entrants.
This Environmental
Impact Assessment (EIA) report studies one of the proposed FCZ sites, i.e. Mirs
Bay FCZ (hereafter referred to as “the Project”). The location plan of the Project is shown in Figure 1.1.
The
Project aims to establish a new FCZ at Mirs Bay to facilitate the sustainable
development of the local mariculture sector.
The scope of the Project includes:
§ Assembly and anchorage of fish
farm structures which are manufactured off-site, including fish rafts / cages, auxiliary facilities and mooring
system, within the Project site; and
§ Marine fish culture activities
within the Project site regulated under the Marine
Fish Culture Ordinance (Cap. 353).
No
land-based works, structures and activities will be involved in the Project.
The
Project is a designated project by virtue of Item M.1(a) of Part I of Schedule 2 of
the EIAO, which specifies “A fish culture zone more than 5 ha in size” and
requires an Environmental Permit (EP) under the EIAO for its
construction and operation.
In
accordance with the requirements of Section 5(1)(a) of the EIAO, an
application for an EIA Study Brief for the Project was submitted on 15 October
2019 under EIAO with a Project Profile (PP) (No. PP-592/2019).
An EIA Study Brief (No.ESB-326/2019) for
the Project (hereafter referred to as “the Study Brief”) was issued on 27
November 2019 in accordance with Section 5(7)(a) of the EIAO.
The
purpose of this EIA study is to provide information on the nature and extent of
environmental impacts arising from the construction and operation of the
Project and associated works that will take place concurrently. This information will contribute to decisions
by the Director of Environmental Protection on:
n
the overall acceptability of any
adverse environmental consequences that are likely to arise as a result of the
Project;
n
the conditions and requirements for
the detailed design, construction and operation of the Project to mitigate
against adverse environmental consequences wherever practicable; and
n
the acceptability of residual
impacts after the proposed mitigation measures are implemented.
In more
detail, the specific objectives of this EIA study defined in the Study Brief
are as follows:
(i) to
describe the Project and associated works together with the requirements and
environmental benefits for carrying out the proposed project;
(ii) to
identify and describe the elements of the community and environment likely to
be affected by the Project and/or likely to cause adverse impacts to the
Project, including both the natural and man-made environment and the associated
environmental constraints;
(iii) to
identify and quantify emission sources and determine the significance of
impacts on sensitive receivers and potential affected uses;
(iv) to
identify and quantify any potential losses or damage to flora, fauna and natural
habitats;
(v) to
identify and quantify any potential water quality, marine ecological and
fisheries impacts arising from the construction and operation of the Project
and to propose measures to mitigate these impacts;
(vi) to
identify any landscape and visual impacts and to propose measures to mitigate
these impacts;
(vii) to
identify any negative impacts on sites of cultural heritage and to propose
measures to mitigate these impacts;
(viii) to
propose the provision of infrastructure or mitigation measures so as to minimise
pollution, environmental disturbance and nuisance during construction and
operation of the Project;
(ix) to
investigate the feasibility, effectiveness and implications of the proposed
mitigation measures;
(x) to
identify, predict and evaluate the residual environmental impacts (i.e. after practicable
mitigation) and the cumulative effects expected to arise during the
construction and operation phases of the Project in relation to the sensitive
receivers and potential affected uses;
(xi) to
identify, assess and specify methods, measures and standards, to be included in
the detailed design, construction and operation of the Project which are
necessary to mitigate these residual environmental impacts and cumulative
effects and reduce them to acceptable levels;
(xii) to
design and specify the environmental monitoring and audit requirements; and
(xiii) to
identify any additional studies necessary to implement the mitigation measures
of monitoring and proposals recommended in this EIA report.
This EIA Report
has been prepared in accordance with the requirements in the EIA Study Brief (No. ESB-326/2019) and the Technical Memorandum on Environmental Impact Assessment Process issued under the EIAO (EIAO-TM) for the Project, the aim being to obtain
an EP under the EIAO.
The description of the Project presented
in this EIA Report has been based on the best available information from AFCD
that describes the relevant construction activities, operational details, and
baseline information describing the conditions relating to the Project and its
surrounding environment.
Project
Profile No. PP-592/2019 was exhibited to the public for comments on 16 October
2019. Public offered their views during
the 14-day public inspection period of the Project Profile. The key comments received from the public and
responses are summarised in Appendix
1A.
During the course
of this EIA Study for the Project, AFCD have been reaching out to potential
stakeholders to explain the Project, and seek their views and opinions. Stakeholder engagement activities, which
commenced in June 2021, included briefings and meetings with interest groups
including members of the Legislation Council, fishermen groups, mariculturists,
environmental bodies etc. Details of the
stakeholder engagement activities undertaken and the feedback received are
presented in Appendix 1A. The feedback and opinions obtained from the
stakeholders have been fully considered and incorporated, where applicable, as
part of the technical assessments undertaken in this EIA Study.
