Project Information
The scope of the Project involves the phased
construction and operation of up to two additional combined cycle gas turbine
(CCGT) units (with an installed capacity of up to 600 MW each) at the
BPPS. The additional generation units
will be of CCGT configuration using natural gas as the primary fuel. It is a Designated Project under the Environmental Impact Assessment Ordinance
(Cap. 499) (EIAO). The
current EM&A
Programme only includes the CCGT Unit No. 1.
An
EIA of the Additional Gas-fired Generation Units Project was prepared in
accordance with the EIA Study Brief (No. ESB-286/2015) and the Technical
Memorandum of the Environmental Impact Assessment Process (EIAO-TM)
and submitted under the EIAO in February 2016.
Subsequent to the approval of the EIA (EIAO Register Number
AEIAR-197/2016), an Environmental Permit (EP-507/2016) (EP) for CCGT Unit
No. 1 was granted by the Director of Environmental Protection (DEP) on 14 June
2016. A Further Environmental Permit
(FEP-01/507/2016) (FEP) was granted to the Contractor, Chun Wo
Foundations Limited, of the CCGT Unit No. 1 on 9 December 2016.
The proposed location for the Project is within the
existing boundaries of the BPPS site.
The size of the land reserved for the additional generation units and
the associated facilities (the Project Site) is about 40,000 m2. Construction works for CCGT Unit No. 1 is
currently ongoing at the Project Site.
The works area for the Project is shown in
Annex A.
A summary of the major construction activities undertaken in this
reporting period is shown in Table 2.1. The construction programme is presented in Annex B.

5.1
Waste
Management
The waste generated from this Project includes inert construction
and demolition (C&D) materials, and non-inert C&D materials. Non-inert C&D materials are made up of
general refuse and recyclable wastes such as plastics and paper/cardboard
packaging waste. Steel materials
generated from the project are also grouped into non-inert C&D materials as
the materials were not disposed of with other inert C&D materials. With reference to relevant handling records
and trip tickets of this Project, the quantities of different types of waste
generated in the reporting month are summarised in Table 5.1. Details of waste management data are
presented in Annex E.

Environmental Site Inspection
Joint weekly site
inspections were conducted by representatives of the Contractor, CAPCO Project
Team and ET on 6, 13, 20 and 27 July 2017.
The representative of the IEC joined the site inspection on
20 July 2017.
No non-compliance was recorded during the site inspections.
Findings and recommendations
for the site inspection in this reporting month are summarised as follows:
6 July 2017
· There were no major observations.
13 July 2017
· There were no major observations.
20 July 2017
· The Contractor (Chun Wo) was reminded to plug
the drip tray for the generator to prevent potential chemical leakage.
Regarding the planter audit, CAPCO was recommended to:
· conduct close monitoring for BPT800 and BPT946; and
· replace BPT773,
BPT786, BPT794 and BPT805 after construction period.
27 July 2017
· The Contractor (Chun Wo) was reminded to spray
the stockpiles and dusty materials with water to maintain the entire surface
wet.
All follow-up actions
requested by ET and IEC during the site inspections were undertaken as
reported by CAPCO and the Contractors.
The abovementioned environmental issues had been addressed and mitigated
during the reporting period.

Conclusions
This 8th monthly Environmental
Monitoring and Audit (EM&A) Report presents the EM&A works undertaken
during the period from 1 July to 31 July 2017 in accordance with the EM&A Manual and the requirements of EP-507/2016 and
FEP-01/507/2016.
No non-compliance event was recorded during the reporting month.
No environmental complaint, summon
or prosecution was received during the reporting month.
The Contractors have implemented possible and feasible mitigation
measures to mitigate the potential environmental impacts during
construction. The ET will continue to
keep track of the EM&A programme to ensure compliance of environmental
requirements and the effectiveness and efficiency of the mitigation measures
implemented. If necessary, the
Contractors will provide more mitigation measures to further alleviate the
impacts.
