1. INTRODUCTION
1.1 Background
1.1.1 The Mai Po Nature Reserve has served Hong Kong as one of the most valuable ecological assets
in the city, and is managed by the World Wide Fund for Nature Hong Kong (“WWF”). WWF
proposes to update of an existing concrete footpath of about 1.5m wide to a raised wooden
boardwalk of about 1.65m wide, construction of a new three-storey tower hide (TH2) and the
associated access wooden boardwalk of about 156m long and 1.65m wide; and construction of
a new three-storey tower hide (TH3) and the associated access wooden boardwalk of about 85m
long and 1.65m wide. The location of the Project as shown in the Appendix A of this report.
1.1.2 The project site is located in Mai Po Nature Reserve (MPNR) where has been managed by World
Wide Fund for Nature Hong Kong (“WWF”) since 1984. More than 20,000 people per year
visiting the MPNR and growing in visitor numbers is anticipated. Most of the existing facilities
have been in use for more than 20 years, in order to cater for an increasing number of visitors
and providing the good condition of facilities in the future, the upgrade of infrastructure is
proposed. The WWF had completed an Environmental Impact Assessment (EIA) and is the
Permit Holder.

ii. Record the field condition including weather conditions and any other potential source
of interference;
iii. Lower the sampler into water body and rinse it with water in the target water body;
iv. Fill the sampler until adequate sample is collected. Replicate sample at each monitoring
location is required;
v. Rinse the bottles by the sample before transferring samples into containing bottles;
vi. Rinse the probe of multimeter with distilled water;
vii. Measure and record temperature, turbidity, pH value and DO of each bottle of sample;
viii. Bottles containing sample is stored temporarily in insulation box with ice until reaching
the laboratory.
2.3.2 The water samples shall be delivered to a HOKLAS laboratory as soon as possible for
analysis, which shall start the next working day after the collection of samples. Analyses shall
follow standard methods as described in APHA Standard Methods for the Examination of
Water and Wastewater, 19th Edition, unless otherwise specified (APHA 2540D for SS and
APHA 5520C for O&G). The QA/QC details shall be in accordance with the requirements
of HOKLAS.
2.4 Data Management and QA/QC
2.4.1 The baseline monitoring data were handled by the ET’s in-house data recording and
management system. Laboratory responsible for laboratory analysis would follow QA/QC
requirements as set out under HOKLAS scheme.
2.5 Discussion and Recommendations
2.5.1 The monitoring of water quality was conducted during typical wet season in Hong Kong.
2.5.2 Review of the conditions may need to be conducted regularly, in particular during weather
condition changes. If the changes in baseline conditions are evident, the environmental
performance criteria should be re-established by agreement of the ER and IEC and submitted
to EPD for endorsement.
2.6 Results and Observations
2.6.1 All water quality monitoring was conducted as scheduled in the reporting month. The
water quality monitoring schedule for this reporting month is shown in Appendix D.
2.6.2 The monitoring results and graphical presentation of water quality monitoring at the
monitoring stations are shown in Appendix E.

3 ENVIRONMENTAL SITE INSPECTION
3.1 Solid and Liquid Waste Management Status
3.1.1 In accordance with the EM&A Manual, waste management was audited during weekly site
audit to determine if wastes are being managed in accordance with the Waste Management
Plan (WMP) prepared for the Project and the relevant legislative and contractual
requirements. Waste management practice including waste handling, storage, transportation
and disposal were audited.
3.1.2 Proactive measures have been undertaken to make use of construction and demolition (C&D)
materials to minimize the waste generated. On-site sorting and screening of excavated
materials have been carried out to recover any recyclable portions. Inert C&D materials were
used on-site for backfilling works.
3.1.3 The Contractor is advised to minimize the wastes generated through the recycling or reusing.
All mitigation measures stipulated in the EM&A Manual and waste management plans shall
be fully implemented. The status of waste flow generation are summarised in Appendix G.
3.2 Site Audits
3.2.1 Site audits were carried out by ET on weekly basis to monitor the timely implementation of
proper environmental management practices and mitigation measures on the Contract site.
3.2.2 Site audits were conducted by ET with the representative of the client’s Representative and
the Contractor on 5, 19 June 2023 in the reporting month. Joint site audits with the
representative of the Client representative, the Contractor and IEC were carried out on 12
and 26 June 2023.
3.2.3 During site inspections in the reporting month, no non-compliance was identified. The
observations and recommendations made during the audit sessions are summarised in Table
3.1.

3.3 Implementation Status of Environmental Mitigation Measures
3.3.1 According to the EIA Report, Environmental Permit and the EM&A Manual of the Project,
the mitigation measures detailed in the documents are recommended to be implemented
during the construction phase. An updated summary of the Environmental Mitigation
Implementation Schedule (EMIS) is provided in Appendix F.
3.3.2 During site inspections in the reporting month, the Contractor’s readiness with the mitigation
measures during dry season against dust emission was found generally satisfactory despite
some observations/recommendations as detailed above were raised.
3.3.3 Waste generated from this Project includes inert C&D materials and non-inert C&D materials.
Non-inert C&D materials are made up of general refuse and waste that cannot be reused or
recycled and has to be disposed of at the designated landfill sites. The amount of wastes
generated by the construction works of the Project during the reporting month is shown in
Appendix G.

4.3 Summary of Environmental Complaint
4.3.1 In accordance with the EM&A Manual, complaints should be referred to the ET for action.
During the complaint investigation works, the ET and IEC as established according to EP
can carry out Ad-hoc site inspections to identify the source of the complaint, review the
effectiveness of the Contractor’s remedial measures and the updated situation once received
the complaint. In addition, additional monitoring and audit can also be arranged immediately
to verify the situation if necessary. ET and IEC will also oversee the circumstances that
leading to the complaint do not recur. Moreover, ET and IEC can cooperate efficiently with
the Contractor on site for completion of the investigation.
4.3.2 There was no environmental complaint received in the reporting month.
4.4 Summary of Environmental Summon and Successful Prosecution
4.4.1 There was no successful environmental prosecution or notification of summons received
since the Project commencement.

5 FUTURE KEY ISSUES
5.1 Key Issues in the Coming Three Months
5.1.1 The tentative construction programmes for the Project are provided in Appendix K. The
major construction activities undertaken in the coming three months will include:
- Water Quality Monitoring
- Construction of footings
- Construction of wooden boardwalk
- Installation of prefabricated panels and structural frames of TH2 and TH3
5.1.2 With reference to the tentative construction programmes including the indication of coming
three months construction site activities in Appendix K, potential environmental impacts
arising from the above construction activities are mainly associated with water quality,
waste management, landscape and visual and ecology. The foreseeable environmental
impacts were taken into consideration of the planned mitigation measures in the coming
months.
5.2 Monitoring Schedule for the Next Month
5.2.1 The tentative environmental monitoring schedule for the next month is shown in Appendix
