Remarks:
The weekly site inspection for ND/2019/06 has been terminated starting from
19/10/2023 since the termination proposal was approved by EPD on the same day.
10.2 During site inspections in the reporting month, no non-conformance was
identified. The observations and recommendations made during the audit sessions
are summarised in Table 10.2. Any outstanding and recurrence deficiencies are
presented in Table 10.3.
10.3 All construction activities with significant environmental impact
undertaken by Contract No. ND/2019/06 was substantially completed in March 2022
and the majority of outstanding works were also completed
in April 2022 with defect rectification works remained. The
outstanding installation works were the short-duration works which would be
completed within 2 months during the 1-year defect correction period,
originally estimated.
10.4 Due to problems in material
deliveries from Mainland China in 2022, the completion date of the outstanding
works would be extended to June 2023 tentatively. However, in June 2023, more
defects were found during the handover inspection so the rectification works
were undertaken until July 2023 when all works were completed.
10.5 The weekly site inspection and EM&A Reporting for ND/2019/06 were
maintained until the termination proposal for ND/2019/06 has been endorsed by
the IEC (17 Aug 23), the Engineer (26 Aug 23) and the Project Proponent (19 Sep
23) followed by approval from EPD (19 Oct 23) in accordance. The procedure for
termination proposal for ND/2019/06 is in accordance with section 15.4.2 of
updated EM&A Manual.

Status of Water Quality Mitigation Measures
10.7 The water
quality mitigation measures detailed in the EIA Report and the Updated EM&A
Manual are recommended to be implemented during the construction phase. Water
quality mitigation measures implemented by the contractors were closely
monitored to prevent water pollution, especially during rainy season. An

Ecological
Mitigation Measures ¡V Creation of Long Valley Nature Park (LVNP)
10.11 Based on the
findings of the EIA Report, the area of Long Valley has been assessed as of high to very
high ecological value and is the largest contiguous area of freshwater wetland
habitats in Hong Kong. To safeguard the ecological value of Long Valley, about
37 hectares of land in Long Valley has been proposed to develop into Long
Valley Nature Park (LVNP) for conserving and enhancing the ecologically
important environment as well as for compensation of the wetland loss due to
the NDA development.
10.12 LVNP is developed according
to the approved Habitat Creation and Management Plan (HCMP) submitted under
EP-468/2013/A. HCMP provides a framework and specifications for development and
management of LVNP and guides the development to maintain and enhance the 37
hectares of low-lying wetland habitats.
10.13 Regarding the design, the zoning of land use in LVNP is intended to
maintain the existing mosaic pattern of wet and dry agriculture, while
controlling the activities that could potentially disturb target habitats and
species. LVNP will be divided into three broad zones of land use as below:
• Biodiversity Zone of about 21 hectares largely designated for
biodiversity conservation through cultivation of specified crops and habitat
management.
• Agricultural Zone of about 11 hectares designated for commercially
focuses crop production and eco-friendly agricultural practice for farming.
• Visitor Zone of about 5 hectares designed to accommodate visitors as
well as storage and other facilities and for educational purposes.
10.14 The construction of LVNP started in late 2019 and was expected to
be completed in 2023. During the construction period, the progress of construction and wetland
enhancement works has been under observation by different stakeholders including AFCD and green
groups. Close communication between AFCD and CEDD were
conducted to exchange views on conservation, restoration
and management of habitats as well as on the planning and design of the park. In addition, advices from green groups, Hong Kong Bird Watching Society (HKBWS) and
The Conservancy Association (CA), have been taken on habitat management of Long Valley
and potential effects on habitat and wildlife of each individual work conducted
in Long Valley. The last meeting was held on 18 November 2022 to share the progress of LVNP with different
stakeholders, including CEDD, AFCD, CA, HKBWS, Contractor, ET, IEC and farmers.
10.15 Proposals on wetland creation and restoration, dry agricultural land
creation, pond creation, water treatment wetland and design of irrigation
channel were submitted by the Contractor to achieve the objectives stated in HCMP
and accepted by the Engineer with consent from AFCD before implementation. The
Contractor would consult the stakeholders for recommendations and suggestions on
mitigation measures to minimise the environmental
impacts arising from construction works. The progress of works would be
arranged to minimise impacts to avifauna and maintain
the habitat for avifauna. The photographic records of site activities in LVNP
are presented in Table 10.5.
