sequencing plans to minimize the extent and duration of exposed soil surfaces. By carefully
planning the construction activities, the project can reduce the overall risk of erosion and
sedimentation by limiting the amount of disturbed areas at any given time.

5. Biodiversity Preservation and Enhancement:

Preserving and enhancing biodiversity is an important aspect of the Kai Tak Multi-purpose Sports
Complex project. The project implements various mitigation measures to minimize the impact on
local biodiversity and promote its preservation and enhancement.

5.1 Habitat assessment and protection: Prior to construction, a comprehensive assessment of

the project site is conducted to identify existing habitats and species of conservation importance.

Environmental impact assessment

This assessment helps in determining appropriate measures to protect and preserve these habitats
during and after construction.

5.2 Green spaces and landscaping: The project incorporates the creation of green spaces and
landscaping that are designed to enhance biodiversity. This includes the planting of native plant
species, creation of diverse habitats, such as wetlands or meadows, and the incorporation of trees
and vegetation that provide

6. Environmental Monitoring and Management Plan

This evaluation process aims to continuously monitor changes in environmental standards and the

effectiveness of mitigation measures. This helps in the early detection of unacceptable

environmental

degradation and allows for the formulation of corrective actions at an early stage.

6.2 Responsibilities of stakeholders in implementing and overseeing the monitoring plan.

1. Air Quality Impact

Dust suppression measures are expected to ensure acceptable air quality during construction.

Regular monitoring in representative ASR areas is necessary to meet air quality standards. Weekly

site audits should verify the implementation of air quality mitigation measures. The project is
unlikely to exceed air quality targets for all parameters except the annual average of nitrogen
dioxide.

2. Hazard to Life The project poses no expected risks to life or the environment, though monitoring
or auditing is recommending

Environmental impact assessment

3. Noise Impact

Regular noise monitoring and weekly audits are required at national communication offices
during

construction to ensure compliance with noise standards and the effectiveness of mitigation
measures.

During the initial three years of operation, real-time noise monitoring was conducted at selected

locations, especially during events at the main stadium. The results will be reviewed to decide on
the

need for additional monitoring. The indirect impact from crowd and traffic noise during major
events is

During the operational phase

infrequent and considered acceptable. With effective mitigation measures, the remaining impact is

also acceptable.

4. Water Quality Impact Assessment

During construction, marine water quality outside the project site will remain unaffected. If

natural grass is used in fields, operators must follow pesticide regulations and create a rainwater

reuse plan, outlining monitoring locations, frequency, and mitigation procedures. Proper

implementation of these measures will prevent negative impacts on construction water quality,
and

weekly audits will ensure compliance.

5. Sewerage and Sewage Treatment Implications

A drainage system has been implemented to keep sewage and clean stormwater separate.

Contaminated runoff will be managed with interception systems and oil traps. The project will be

connected to public sewers, ensuring no significant water quality issues.

6. Implications for wastewater treatment and sanitation.

 25

Environmental impact assessment

The project will not negatively impact the sewage system in the Kai Tak Development area, and
no

monitoring or auditing is required.

7. Waste Management Implications

Construction waste includes building and demolition materials from excavations, site formation

and demolition, bentonite from foundation works, chemical waste resulting from factory
maintenance,

and general waste. Chemical waste will be generated from equipment maintenance. No adverse

effects on construction waste are expected if mitigation measures are properly implemented.
Weekly

site audits should be conducted to ensure the recommended waste management measures are
being

implemented throughout the construction period.

8. Terrestrial Ecological Impact Assessment

The review and assessment of land pollution issues at the project site have been conducted.

Primarily, contaminated lands identified in the northern area have been cleaned, rendering the site

suitable for intended use. Additionally, there will be no potential land pollution at the project site.

9. Cultural Heritage Impact Assessment

No negative effects on known or potential archaeological sites or built heritage areas.

6.3 Procedures for responding to unexpected environmental issues.

The organizer must also provide a hotline for complaints to respond to complaints from nearby

NSRs immediately.
