11 Conclusions

11.1 Conclusion of EIA Study

11.1.1.1 This EIA Report has provided an assessment of the potential environmental impacts associated with the construction and operation of the Project, based on the engineering design information available during the course of EIA study.

11.1.1.2 The assessment has been conducted, in accordance with EIAO-TM, covering the following environmental issues:

¡P Air Quality Impact

¡P Noise Impact

¡P Water Quality Impact

¡P Waste Management Implications

¡P Land Contamination

¡P Landscape and Visual Impacts

11.1.1.3 The findings of this EIA study have determined the likely nature and extent of environmental impacts predicted to arise from the construction and operation of the Project. During the EIA process, environmental control measures have been identified and incorporated into the planning and design of the Project, to achieve compliance with environmental legislation and standards during both the construction and operation phases. The Implementation Schedule listing the recommended mitigation measures is presented in Appendix 9.1.

11.1.1.4 With the implementation of the mitigation measures, the Project would be environmentally acceptable with no unacceptable residual impacts on the environmentally sensitive receivers and resources. Table 11.1 below summarizes the key environmental outcomes and benefits that have accrued from the environmental considerations and analysis during the EIA process and the implementation of environmental control measures of the Project. Appendix 11.1 presents the summary of environmental impacts and Appendix 11.2 presents the summary of key assessment assumptions, limitation of assessment methodologies and related prior agreements with the Director.

11.1.1.5 The various sections of this EIA Report have presented the measures to minimize the potential environmental impacts associated with the Project throughout the construction and operational phases. The key measures to minimize the environmental impacts are summarized in Section 10.

11.1.1.6 An Environmental Monitoring and Audit (EM&A) programme has been developed to ascertain and verify the assumptions implicit to, and accuracy of, EIA study predictions. EM&A requirements have been recommended, where necessary, to check on project compliance of environmental legislation and standards. These are presented in a separate stand-alone EM&A manual.

Table 11.1 Summary of Key Environmental Outcomes and Benefits

Environmental Issue	Description
Environmental / Social Benefits of the Project	¡P The Project is designed to alleviate the forecast traffic demand from the ongoing WKCD development and also the elevated Nga Cheung Road roundabout, which is already congested by providing connection to the at-grade road at the WKCD and the West Kowloon Highway (Route 3 ¡V West Harbour Crossing Tunnel Area). ¡P With the introduction of a single ramp connecting to the Museum Drive at the WKCD, it will help to disperse traffic away from the busy elevated junction of Jordan Road / Nga Cheung Road and also provide a short cut between the Kowloon Station Topside Developments and the West Kowloon Highway..
Environmentally Friendly Design and Options	¡P Avoidance of Encroachment of Project Road Alignment into Potentially Contaminated Area at the New Yau Ma Tei Public Cargo Working Area ¡P Adoption of environmentally friendly construction method. ¡P Implementation of trip-ticket system ¡P Implementation of EM&A System.
Air Quality Impact	Construction Phase: ¡P Potential dust impact generated from construction activities, such as site clearance (including demolition of existing carriageways), minor excavation with limited backfilling, and wind erosion of exposed area, and emission from Powered Mechanical Equipment (PME) would not be significant. With implementation of suitable practice and mitigation measures, potential impacts on the representative ASRs would not be significant and would be controlled to within relevant standards. Operation Phase: ¡P The ¡§Revised Austin Road Flyover¡¨ would improve annual average NO2 concentrations at the identified ASRs. There would be a decrease in annual average NO2 concentration compared to the ¡§Original Austin Road Flyover¡¨ Scenario which indicated the Project would bring improvements in terms of air quality aspect and no adverse impact would be generated due to the Project during the operation phase. The exceedances of annual average NO2 concentrations predicted at some existing and planned representative ASRs are mainly resulted from the relatively high concentration of background air pollution in this area. In addition, the predicted 19^th highest hourly average NO2, 10^th daily average and annual average RSP and FSP concentrations at all representative ASRs would comply with the respective AQOs.
Noise Impact	Construction Phase: ¡P Potential source of noise impact during construction phase of the Project would be the use of PME for various construction activities. Major construction works of the Project include site clearance (including demolition of existing carriageways), foundation and superstructure works of the proposed road works. No exceedances of construction noise criteria would be predicted. Therefore, adverse construction noise impact arising from the Project would not be anticipated. Operation Phase: ¡P All NSRs would be exposed to a noise level exceeding the noise criteria. The exceedances dominantly contributed by the other existing roads. The contributions from the Project Roads at all representative NSRs are all less than 1.0 dB(A) and all the predicted noise levels of the Project Roads comply with the noise criteria. Therefore, adverse road traffic noise impacts arising from the Project at the representative NSRs would not be anticipated.
Water Quality Impact	Construction Phase: ¡P The key issues from the land-based construction works include wastewater generated from the general construction activities, construction site runoff, sewage from construction workforce and accidental spillage of chemicals. The potential water quality impacts could be mitigated and controlled by implementing the recommended mitigation measures, no adverse water quality impact is expected due to the land-based construction works. Operation Phase: ¡P The only source of potential adverse water quality impact in the operation phase is identified as surface runoff from the minor additional paved areas. The associated water quality impact is expected to be minimal and acceptable, provided that the recommended mitigation measures for the drainage system are properly implemented.
Waste Management Implications	Construction Phase: ¡P Waste types generated by the construction of this Project include C&D materials, chemical wastes and general refuse. Provided that these wastes are handled, transported and disposed of according to the recommended good site practices, adverse environmental impacts are not expected. Operation Phase: ¡P It is expected that no waste will be generated during the operation phase of the Project. As such, it is considered that there should be no adverse environmental impacts.
Land Contamination	¡P Based on the findings of the site appraisal, adverse land contamination impact arising from the Project is not anticipated. The submission of CAP, CAR, RAP and RR are considered not necessary.
Landscape and Visual Impacts	¡P It is considered that the residual landscape and visual impact is acceptable with mitigation measures implemented during construction and operation phases.
