Design Approach |
Key Design Considerations |
Associated Environmental Benefits |
|
Avoidance
of Works within Tai Lam Country Park |
·
No aboveground works within Tai Lam Country
Park. Only tunnelling works and part
of temporary underground adit at the Wah Fat Works Area would be carried out
underneath Tai Lam Country Park. No aboveground works within the Tai Lam
Country Park boundary. ·
After considering the latest geological
information at Tai Lam Country Park, it has been determined that the most
suitable construction method for these tunnel sections is drill-and-blast.
Alternative tunnelling methods, including the use of TBM in Tai Lam Country
Park were duly explored but considered not suitable from the engineering
perspective. |
·
No direct loss of aboveground
natural habitat and resources within Tai Lam Country Park boundary. |
|
Avoidance
of Marine Works |
·
Avoid reclamation and the associated
dredging works within Tuen Mun Typhoon Shelter have been totally avoided. |
·
Avoid the disturbance of seabed,
marine habitat loss and generation and disposal of marine sediment. |
|
Minimisation
of Potential Water Drawdown in Tai Lam Country Park |
·
Good practices and water control
strategies such as including probing ahead, pre-grouting and posting grouting
will be implemented to minimize adverse impact. As a precautionary
measures, monitoring programme will be implemented to monitor the mitigation
measures on groundwater infiltration within Tai Lam Country Park. ·
Drill-and-blast/drill-and-break
tunnel section would be in granite and with sufficient depth below ground,
together with the good practices and mitigation measures, adverse impact on
the change in groundwater table would be insignificant. |
·
Minimised impacts on water
drawdown in Tai Lam Country Park. |
|
Minimisation
of Air Quality Impact |
·
Adopt mitigation measures for
fugitive dust such as regular spray, exposed earth surface covered by
tarpaulins, standard wheel washing facilities at the construction site exits,
vehicle washing at the exit of the barging facility with the provision of
vehicle washing facilities. ·
Provision of 3-side with top cover
and spraying system at unloading points at the barging facility. ·
Blasting to be carried out in a
fully enclosed environment. ·
Avoid using exempted Non-Road
Mobile Machinery (NRMM) where practicable. ·
Site hoardings of not less than
2.4m high should be provided as far as practicable along the site boundary
with provision for public crossing. Taller site hoarding may be considered
for ASRs in close vicinity to the site boundary, subject to actual site
constrains and detailed design. Good site practice shall also be adopted by
the Contractor to ensure the conditions of the hoardings are properly
maintained throughout the construction period. ·
Connect construction plant and equipment
to mains electricity supply and avoid use of diesel generators and
diesel-powered equipment as far as practicable to minimize air quality impact
arising from construction machinery. ·
Close the impermeable blast covers
at tunnel portals prior to blasting works in order to ensure blasting works
in a fully enclosed environment. ·
The engine of the barge shall be
switched-off during berthing as far as practicable. Provision of on-shore
power supply shall also be considered wherever possible to minimize air
quality impact from the marine vessels, with consideration of actual site
constraints or circumstances to be further reviewed during detail design
stage. ·
Close liaison between the
contractors of other concurrent projects and the Project would be maintained
to minimise dusty activities to be conducted concurrently as far as
practicable. ·
During the subsequent design stage
and the operational stage, the ventilation engineer should conduct reviews on
the ventilation scheme covering different periods of a day, taking into
account the contemporary circumstance such as latest traffic forecast,
traffic composition, update on the ambient air quality, etc., and then review
and update the air quality assessment as necessary to demonstrate full
compliance of the AQO. These reviews
would allow the designer and operator to optimize the operation of the
ventilation system without compromising the compliance of AQO. ·
Proper design of any planned air
sensitive uses within the satellite control building and operation area in
Lam Tei, and maintenance compound and training ground and supporting area in
Pillar Point such that any openings, openable windows, and/or FAIs will be
located and avoided from the predicted exceedance zone at 1.5mAG. (e.g., by
provision of fixed glazed window or blank facades, and FAIs to be located
away or proposed air sensitive uses outside the exceedance zone). Further
review of the layout and design of these TMB highway / tunnel operation and
maintenance facilities in Detailed Design Stage to ensure compliance of the
AQOs. For the proposed satellite control building and FAIs for maintenance
compound located within the exceedance zone at 1.5mAG, installation of air
filtering system is recommended. Further review of the air filtering system
and NO2 removal efficiency to ensure compliance of the AQOs in
Detailed Design Stage. |
·

investigation (SI) works, review the Contamination Assessment Plan (CAP)
provided in Appendix 7.1 and
conduct site re-appraisal to confirm whether the proposed SI works (e.g.,
sampling locations, testing parameters etc.) are still valid, and to confirm
the appropriate RBRGs land use scenario for the development. ·
Should any changes in operation which lead
to any new or the relocation of contamination hotspots or occurrence of
spillage or accident be found in the review, supplementary CAP(s), presenting
the findings of the review, the latest site conditions and updated sampling
strategy and testing protocol, should be submitted to EPD for approval. ·
The SI works should be carried out according
to EPD’s approved CAP(s). ·
Contamination Assessment Report(s) (CAR(s))
should be prepared to present the findings of the SI works and to discuss the
presence, nature and extent of contamination. If contamination is identified
in the CAR(s), Remediation Action Plan(s) (RAP(s)) which provides details of
the remedial actions for the identified contaminated soil and/or groundwater
should be developed prior to construction works at the concerned areas.
Submission to EPD for approval of the supplementary CAP(s), CAR(s) and, if
required, RAP would be carried out in stages according to the programme of
TMB. ·
If required, carry out soil/groundwater
remediation works according to EPD approved RAP(s) and submit Remediation
Report(s) (RR(s)) afterwards for EPD approval prior to the commencement of
construction works at the contaminated areas. |
·
Land
contamination issues could be resolved before commencement of construction
works. |
|
Hazard
