Implementation 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 updated summary of the
Environmental Mitigation Implementation Schedule is provided in Appendix Q.
Specific water quality mitigation measures for major construction works in the
reporting month are presented in Table 10.5.

ND/2019/06 was handed over to AFCD for operation since 4 April 2022.
10.10 The Contractors are advised to minimise the wastes generated
through recycling or reusing. All mitigation measures stipulated in the Updated
EM&A Manual and waste management plans shall be fully implemented. The
status of implementation of waste management and reduction measures are
summited in Appendix Q.
Ecological Mitigation Measures – 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 10.6.
