Project Information
2.1
Background
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 2010.
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.
2.2
General Site Description
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

Environmental Monitoring Requirement
3.1
Water Quality Monitoring
In accordance with the EM&A Manual, monitoring works is required at a
frequency of once per week on first year of commissioning of the CCGT Unit No.1. The monitoring details including monitoring requirement, locations of monitoring stations will be confirmed and approved by EPD before commissioning of the CCGT Unit No.1.

Implementation Status of The environmental protection requirements
The Contractor has implemented all the environmental mitigation measures
and requirements as stated in the EIA Report, Environmental Permit (EP) and
EM&A Manual for the installation of CCGT Unit No.1. The mitigation measures recommended in the
EIA report and required by the EP are considered effective in minimising environmental
impacts. The implementation status of
the environmental mitigation measures for this Works Contract during the
reporting period is summarised in Annex D.

Results
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 period are summarised in
Table 5.1. Details of
waste management data are presented in Annex E.
