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 Annex A.

5                                          Monitoring 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 month are summarised in Table 5.1.  Details of waste management data are presented in Annex E.

9                                          Conclusions

This 6th monthly Environmental Monitoring and Audit (EM&A) Report presents the EM&A works undertaken during the period from 1 May to 31 May 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 Contractor has 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 Contractor will provide more mitigation measures to further alleviate the impacts.
