l The major elements of the future ground level road system within KTD include four district distributor roads namely Roads D1, D2, D3 and D4. No new primary distributor road is proposed within KTD. As Roads D1 to D4 are district distributor roads, they are classified as DPs under Item A.1, Part I, Schedule 2 of the EIAO. A section of Road D2 will be running underneath the deck of the proposed Stadium Complex. Based on the latest available information, that section of Road D2 is fully enclosed by decking above and by structure on the sides for more than 100 m and is thus classified as DP under Item A.9, Part I, Schedule 2 of the EIAO. For Road D3, a section of road bridge will be constructed above the 600m gap opening. Therefore, it is classified as DP under Item A.8, Part I, Schedule 2 of the EIAO.
l
Six
sewage pumping stations (SPSs), excluding the
proposed SPS of the DWFI compound at JVBC (JVBC-PS) as described under DP15
below, are located within KTD. As
part of the sewerage improvement scheme in the hinterland to reduce the
pollution loading in KTAC, DSD will initially construct two new SPSs, namely PS1 and PS3. These two SPSs
are tentatively programmed to be completed in 2012 to convey sewage flow
generated from the hinterland to To Kwa Wan Preliminary Treatment Work and the Environmental
Permit No. EP-314/2008 covering PS1 and PS3 had been issued to DSD on 6 October
2008. PS6 will have to be completed
in later
l All these SPSs, except PS6, are with an installed capacity of more than 2000 m3 per day and are located within 150m from existing and/or planned residential area or educational institution, therefore these SPSs are classified as DPs under Item F.3, Part I, Schedule 2 of the EIAO.
l
The proposed PS6 is located near the
southern tip of the former
l The scope of DP3a and DP3b is primarily to decommission the remaining facilities, structures and buildings within the former Kai Tak Airport that were not covered under the previous EIAs on decommissioning of former Kai Tak Airport (namely EIAs for DP4 and DP5). The remaining sites within the former Kai Tak Airport yet to be decommissioned include the ex-GFS building and the Radar Station in the South Apron area (under DP3a), and the Hong Kong Aviation Club (including the adjacent area) and the EMSD Headquarters in the North Apron area (under DP3b). For the decommissioning of the Hong Kong Aviation Club, no soil remediation works would be necessary (see Section 10) and no building demolition is anticipated.
l The decommissioning of airport facilities is classified as DP under Item 1, Part II, Schedule 2 of the EIAO.
l
This DP proposes to
decommission the remaining structures and buildings and the abandoned
facilities associated with the former
(i) Demolish remaining existing structures / building and remove abandoned facilities of the former Kai Tak Airport within the project boundary of this DP including the off-shore disused fuel dolphin and the associated connecting abandoned fuel pipelines;
(ii) Identify and clean up contaminated areas associated with the previous airport operation within the project boundary of this DP as identified during the EIA; and
(iii) Implement appropriate mitigation measures to ensure the site would be safe and free of hazards for the planned future use.
l This decommissioning project is classified as DP under Item 1, Part II, Schedule 2 of the EIAO. The potential environmental impacts arising from this DP have been assessed in the approved EIA report (EIAO Register No.: AEIAR-114/2007).
l
Kai Tak
Airport North Apron covers an area of about 164 hectares. The purpose of
this DP is to decommission the disused facilities and clean up the ground
contaminations at the north apron of the former
l
Development of the
cruise terminal at Kai Tak would require dredging
operations exceeding 500,000m3 at the existing seawall at the
southern tip of the former
l
The Stadium Complex
site is located on the southeastern side of the
former
l The proposed main Stadium with a capacity to accommodate more than 10,000 persons is classified as a DP under Item O.6 & O.7, Part I, Schedule 2 of the EIAO. The proposed Stadium Complex will be designed, constructed and operated by the others. The associated environmental impacts will be adequately addressed in a further detailed EIA study to be prepared and submitted under the EIAO by the respective project proponent.
l The separation between Kwun Tong waterfront and the Runway tip is around 600m and the walking distance between key destinations on either side could be over 1km. Given the very strong public request and in view of the potential economic and social benefits in providing such link, a reservation has nevertheless been made on the RODP.
l The implementation strategy of such transportation link is still under investigation and it will be designed, constructed and operated by the others. Since the proposed transportation link would constitute a road or railway bridge more than 100 m in length between abutments, it would therefore be classified as a DP under Item A.8, Part I, Schedule 2 of the EIAO. The associated environmental impacts will be adequately addressed in a further detailed EIA study to be prepared and submitted under the EIAO by the respective project proponent.
l New 400kV electricity substation will be provided at Site 2A7 to cater for the electricity demand generated by KTD. The (400 kV) substation and transmission line are classified as a DP under Item H.1, Part I, Schedule 2 of the EIAO.
l
The
Electro-Magnetic Field (EMF) effects would be the operational issue of a 400kV
electricity substation. With
reference to the Project Profile for Extension Project for Tsuen
Kwan O 400kV substation, the electric and magnetic field strength of a 400kV
electricity substation is well below relevant criteria even at substation
boundary (~10m from the substation building). Given the distance between the proposed
electricity substation at Site 2A7 and the adjacent sub-divisional fire
station, ambulance depot with department quarters (Site 2A8) and the nearest
residential site (Site 2B6) is 10m and 35m respectively. The EMF effects would be insignificant.
l In addition, the new substation will be designed, constructed and operated by the respective electricity provider. The associated environmental impacts will be adequately addressed in a further detailed EIA study to be prepared and submitted under the EIAO by the respective project proponent.
l The proposed Trunk Road T2 starting at the downstream end of Kai Tak Nullah is a dual 2-lane trunk road runs mostly at grade along the South Apron area and then drops down after crossing the Jordan Valley multi-cells box culvert running in tunnel form beneath the Kwun Tong Typhoon Shelter (KTTS) and further connects with Tseung Kwan O-Lam Tin Tunnel at Cha Kwo Ling side. The proposed Road T2 is about 3.6km long with 2km long of immersed tunnel. For the construction of the immersed tunnel, dredging works would be required in the vicinity of the tunnel alignment along the waterfront of the Kwun Tong area. It will also be required to realign a section of the existing Kwun Tong submarine outfall. The estimated total dredging volume would likely exceed 500,000 m3. Road T2 is classified as a DP under Items A.1, A.7, C.12 & F.6, Part I, Schedule 2 of the EIAO. The associated environmental impacts will be adequately addressed in a further detailed EIA study to be prepared and separately submitted under the EIAO by CEDD.
l
The proposed CKR is a 4.7km long dual 3-lane trunk
road, including a dual 3-lane tunnel of about 3.9km length. On the west, it connects with the
l The proposed CKR will be an expressway and is classified as a DP under Items A.1 and A.7, Part I, Schedule 2 of the EIAO. The associated environmental impacts will be adequately addressed in a separate EIA report to be prepared and submitted under the EIAO by the Highways Department in accordance with the EIA Study Brief No. ESB-156/2006 issued under the EIAO in November 2006.
l
The proposed SCL is a railway extension
of the Ma On Shan Railway commencing at the existing MTRC Tai Wai Station,
terminating in the Central Business District of Hong Kong
l The proposed SCL is classified as a DP under Items A.2 and A.7 Part I, Schedule 2 of the EIAO. The associated environmental impacts will be adequately addressed in a further detailed EIA study to be prepared and submitted under the EIAO by the respective project proponent.
l The transport depot for the proposed Environmentally Friendly Transport System (EFTS) is still subject to further detailed study and will be designed, constructed and operated by private developer. Based on the EFTS routings reserved on the RODP, a depot is required as the maintenance and storage facilities for the EFTS.
l At this time, the design for EFTS depot is generic, with no detail provided, and the requirements and layout of the maintenance facility are subject to development as the planning and system design progresses, which would be investigated by the future developer / operator of the EFTS.
l If the proposed transport depot is located less than 200m from the nearest boundary of an existing or planned residential area; place of worship; educational institution; or health care institution, it would classified as a DP under Item A.6, Part I, Schedule 2 of the EIAO. The associated environmental impacts will be adequately addressed in a further detailed EIA study to be prepared and submitted under the EIAO by the respective project proponent.
l
Twin 400mm diameter
steel submarine gas pipelines are currently aligned 235m west of and parallel
to the former Kai Tak Airport runway. The pipelines serve as a strategic gas supply to
l
The proposed submarine gas pipeline
relocation is classified as a DP under Items C.12 and H.2, Part I, Schedule 2
of the EIAO. The associated environmental impacts will be adequately
addressed in a separate EIA report to be prepared and submitted under the EIAO
by the
l In order to alleviate the pollution problem at the Kai Tak Approach Channel (KTAC), the Drainage Services Department (DSD) will commission a project which includes the construction of a dry weather flow intercepting (DWFI) compound and sewage pumping station and the associated discharge pipe at JVBC.
l The proposed sewage pumping station of the DWFI compound, is with an installed capacity of more than 2000 m3 per day and is located within 150m from a planned hospital development, so the proposed sewage pumping station is classified as a DP under Item F.3, Part I, Schedule 2 of the EIAO. The associated environmental impacts will be adequately addressed in a further detailed EIA study to be prepared and submitted under the EIAO by DSD.
l For the long-term sewerage impact, the sewerage impact assessment results show that the capacity of To Kwa Wan PTW would be exceeded only because of the potential population increase in Kwun Tong TPTW catchments in 2030 and beyond. It is understood that the project of investigation for the upgrading of Kwun Tong Sewage Preliminary Treatment Works by EPD will commence in June/July 2008 and will last for 17 months. The details of the upgrading of Kwun Tong PTW will be determined under that project.
l The proposed upgrading of Kwun Tong PTW is classified as a DP under Item F.1, Part I, Schedule 2 of the EIAO. The associated environmental impacts will be adequately addressed in a further detailed EIA study to be prepared and submitted under the EIAO by EPD.
