9.8 Summary of Environmental
Monitoring and Audit Requirements
TABLES
Table 9.1 Summary
of Required EM&A
9.1.1
This section further elaborates the requirements of
Environmental Monitoring and Audit (EM&A) for the construction and
operational phases of the Project, based on the assessment results of the various
environmental issues.
9.1.2
Details of the EM&A programme are presented as
part of this EIA Study in a separate stand-alone EM&A Manual. The
Environmental Mitigation Implementation Schedules (EMIS) for the recommended
mitigation measures are, also, included in the EM&A Manual.
Construction Phase
9.2.1
Dust suppression measures for construction dust are
identified. These include restriction of heights from which materials are
dropped and use of regular watering to reduce dust emissions. With the
implementation of good site practices and sufficient dust suppression measures,
air quality impacts are predicted to be insignificant and no residual impacts are
anticipated during the construction phase.
9.2.2
As a result, no dust monitoring is considered to be
required. However, regular weekly site
inspections are recommended to ensure proper implementation of the proposed
mitigation measures. Details are
presented in Section 4 of the
EM&A Manual.
Operational Phase
9.2.3
The potential air quality impacts with respect to
sulphur dioxide (SO2 (10-mins)) have been evaluated and no adverse
impacts are anticipated due to the operation of the proposed helipad.
Therefore, EM&A is considered not necessary.
9.3.1
A Quantitative Risk Assessment has been conducted
to evaluate the risk associated with the proposed helipad at the New Acute
Hospital, the Kerry Dangerous Goods Warehouse (KDGW) and the LPG Filling
Station at Cheung Yip Street. The predicted individual and societal risks have
been found to be in compliance with the risk criteria stipulated in Section 2
of Annex 4 of the TM-EIAO. Therefore,
no EM&A is required for the construction and operational phases.
Construction
Phase
9.4.1
The construction noise assessment has concluded
that there would be no adverse noise impacts expected at the representative
noise sensitive receivers (NSRs). Therefore,
no mitigation measures are required and construction noise monitoring is not considered
necessary. However, good site
practices are still recommended to minimise the noise levels during the construction
phase.
9.4.2
Regular site inspections of at least once per week are
recommended to ensure that the good site practices are implemented. Details are presented in Section 5 of the EM&A Manual.
Operational
Phase
9.4.3
Noise from the helicopter operations would be the key
noise source during the operational phase. Nevertheless, with the
implementation of proposed mitigation measures, the predicted noise levels
would not exceed the relevant criteria.
9.4.4
The EM&A Manual details the proposed noise mitigation
measures during the operational phase, including setback of the helipad deck and
provision of a noise barrier and noise reducers. The Project Proponent will ensure these
measures are implemented.
9.4.5
Should there be any complaints from the local
community regarding the helicopter noise, they may lodge their complaints with the
relevant Authority. The complaint
handling procedures are detailed Section
5 of the EM&A Manual.
Construction Phase
9.5.1
During the construction phase of the proposed
helipad, only small quantities of non-inert Construction & Demolition (C&D)
waste would be generated as the helipad will be constructed using a prefabricated
steel truss. No non-recyclable C&D waste is expected. Also, chemical waste
and general refuse to be generated are expected to be minimal. Therefore, adverse
environmental impacts associated with waste are not anticipated. Nevertheless, weekly site inspections and
audits are recommended to ensure good site practices are properly implemented
as detailed in Section 6 of the
EM&A Manual.
Operational Phase
9.5.2
The operation of the helipad would not generate
waste. Therefore, no EM&A is required for the operational phase.
Construction
Phase
9.6.1
The visual impacts during construction phase have
been evaluated based on the proposed construction method and duration and no
visual impacts are anticipated. Therefore, no EM&A is required.
Operational
Phase
9.6.2
Potential glare impacts during the daytime and
lighting impacts during nighttime operations of the helipad have been evaluated.
The impacts are considered to be insignificant
and, therefore, no EM&A is considered to be required. However, mitigation
measures are still recommended to minimise the lighting impacts during
operational phase at nighttime, which include switching on the landing lights
of the helicopter and the perimeter lights of the helipad only during approach
and departure. Details are
presented in the EMIS in the EM&A Manual. Hospital Authority (HA) shall be
responsible for the on-going management and maintenance of the proposed mitigation
works throughout the operational phase.
Construction
Phase
9.7.1
The potential water quality impacts associated with
surface runoff during the construction phase have been evaluated. With the
implementation of good site practice and recommended mitigation measures, there
would be no adverse impacts anticipated during the construction of the proposed
helipad. Regular site inspections should
be carried out to ensure the proposed measures are properly implemented, as
detailed in Section 8 of the
EM&A Manual.
Operational
Phase
9.7.2
There is no EM&A required during the
operational phase of the proposed helipad. However, the project proponent will
apply for a discharge license for the effluent from NAH including the
fire-fighting system for the helipad.
9.8.1
Environmental monitoring is considered not
necessary. Nevertheless, the required environmental inspections and audits are
summarized in Table 9.1 below.
