12.1.1
This section further elaborates the requirements of EM&A
for the construction and operation of the Project, based on the assessment
results of various environmental issues.
12.1.2
The objectives of carrying out EM&A for the Project
include the following:
Ÿ
to provide a database against which any short or long
term environmental impacts of the Project can be determined;
Ÿ
to provide an early indication should any of the
environmental control measures or practices fail to achieve the acceptable
standards;
Ÿ
to monitor the performance of the Project and the
effectiveness of mitigation measures;
Ÿ
to verify the environmental impacts predicted in this
EIA;
Ÿ
to determine project compliance with regulatory
requirements, standards and government policies;
Ÿ
to take remedial action if unexpected problems or
unacceptable impacts arise; and
Ÿ
to provide data to enable an environmental audit.
12.1.3
The following sections summarise the recommended EM&A
requirements. Details of EM&A
are provided in a stand-alone EM&A Manual.
Construction
Phase
12.2.1
With implementation of the proposed dust suppression measures
stipulated in the Air Pollution Control (Construction Dust) Regulation, good
site practices and comprehensive dust monitoring and audit, the dust impact
would be further diminished.
12.2.2
Dust monitoring and auditing is recommended in the EM&A Manual
to ensure the efficacy of the control measures.
Operation
Phase
12.2.3
There will be no exceedance of AQOs at the sensitive
receivers. No mitigation measures
or environmental monitoring are considered necessary during the operation phase
of the Project.
Construction
Phase
12.3.1
Construction noise impacts from the Project would be expected
at the NSRs identified in this EIA.
Appropriate mitigation measures such as adoption of quiet PMEs, movable noise barrier and scheduling of PMEs/construction
activities are required in order to alleviate the impacts to meet the
EIAO-TM criteria. Noise monitoring
during construction phase will be carried out to ensure that such mitigation
measures are implemented properly.
Operation
Phase
12.3.2
After completion of the Project, traffic noise monitoring
should be carried out at the NSRs in the vicinity of the recommended direct
mitigation measures. The purpose of this monitoring is to ensure that the
proposed mitigation measures are effective to alleviate traffic noise impact. Highways
Department will be responsible for the operational phase monitoring. Qualified
environmental team should be employed to carry out the proposed monitoring. The
parameters, monitoring equipment, locations and procedures are presented in
detail in the EM&A Manual.
Construction
Phase
12.4.1
The water quality assessment has concluded that the identified
water quality impacts could be minimized by implementing the recommended
mitigation measures for the construction works, such as control measures on
runoff and drainage from the work areas to minimise construction run-off and
proper site management and good housekeeping practices. No unacceptable
residual water quality impact would be expected. Any effluent discharges
from the site would be required to comply with the terms and conditions of a
discharge licence, issued by EPD, under the WPCO.
12.4.2
It is recommended
that regular site inspections be undertaken to inspect the construction
activities and works areas in order to ensure the recommended mitigation
measures are properly implemented.
Operation
Phase
12.4.3
No residual impact is anticipated during operation stage of
the Project, EM&A requirement is considered not necessary.
12.5.1
Waste management will be the contractor’s responsibility to
ensure that all wastes produced during the construction of the Project are
handled, stored, reused and disposed of in accordance with the recommended good
waste management practices and EPD’s regulations and requirements. The mitigation measures recommended in
Section 6 should form the basis of the site Waste Management Plan to be
developed by the Contractor at the construction stage.
12.5.2
It is recommended that the waste arisings generated during the
construction activities should be audited periodically to determine if wastes
are being managed in accordance with approved procedures and the site Waste
Management Plan. The audits should
look at all aspects of waste management including waste generation, storage,
reuse, transport and disposal. An
appropriate audit programme would be to undertake a first audit near the
commencement of the construction works, and then to audit on a quarterly basis
thereafter. In addition, the
routine site inspections should check the implementation of the recommended
good site practices and other waste management mitigation measures.
12.6.1
Based on the findings from the desktop studies and site
inspection, no contaminated sites were identified within/in vicinity of the
Project boundary. No adverse environmental impacts on land contamination for
the widening of Tuen Mun Road
at Tsing Tin Interchange are anticipated. As a result, no monitoring programme
specific for land contamination would be required.
12.7
Ecology
12.7.1
The ecological assessment concluded that only minor impacts
would be resulted from the proposed works and these impacts would be further mitigated by proposed
measures. Therefore, apart from regular environmental site auditing of the implementation of mitigation
measures as recommended in Section 9 of this EIA, no specific ecological
monitoring programme would be required under this project.
12.8.1
There is no substantial increase of risk to construction
workers, nearby population and transient population due to widening of the TMR
during construction and operation stages. Mitigation measures to reduce risk
induce by the project is considered not required. However, the number of construction workers should be kept
at the same level as the assessment.
12.8.2
In addition, development of an evacuation plan and procedures,
conducting induction training for construction workers together with performing
periodic drill during construction phase are recommended as a good
practice.
12.9.1
The EIA has recommended landscape and visual mitigation
measures to be implemented during construction and operation phases of the
Project. The EM&A is required
to ensure that the proposed mitigation measures are effectively implemented.
12.9.2
Baseline monitoring is required to record baseline conditions
of the site, in particular, changes of each landscape resource, landscape
character area and the view conditions of each visually sensitive receiver. Parameters used to describe changes in
each of the above should be the same as in Section 10 of EIA.
12.9.3
The baseline monitoring should be conducted as a one-off site
survey prior to commencement of any construction works.
12.9.4
During construction phase, all mitigation measures proposed in
the EIA should be implemented by the Contractor and would be audited by a
landscape auditor of the Environment Team, on a regular basis to ensure
compliance with the intended aims of the measures. Site inspection should be undertaken at least once every two
weeks throughout the construction period.
12.9.5
The landscape auditor should also audit the operation phase
mitigation measures proposed in the EIA report and as depicted in the Landscape
Mitigation Plan to ensure that they are fully implemented within the Project
design and construction.
12.9.6
The detail monitoring and audit requirements are presented in
detail in the EM&A Manual.
12.10
Cultural
Heritage
12.10.1 There
is no cultural heritage impact arising from the construction and operation of
the Project, therefore, monitoring and audit requirement is considered not
necessary.
