No adverse water quality impact is
anticipated during the construction phase with the implementation of good site
practices and appropriate mitigation measures in accordance with the Practice Note for Professional Persons
on Construction Site Drainage (ProPECC PN 1/94) and other relevant
guidelines. The recommended mitigation measures
include the provision of dedicated propriety treatment system and associated
site runoff collection system.
In order to ensure no adverse water
quality impact will arise from the construction of the Project, it is necessary
to undertake regular environmental audits and site inspections to ensure those
recommended mitigation measures were properly implemented. The requirements of the environmental
audit programme were set out in Section 8
of the Manual.
The audit programme will verify the
implementation status and evaluate the effectiveness and stability of the
mitigation measures.
The mitigation measures recommended in the
EIA Study are outlined in the Environmental Mitigation Implementation Schedule
(EMIS) (Annex B).
In the event of complaints, or
non-compliance / area of improvement is observed, the ET and the Contractor
should be responsible for reviewing the effectiveness of these mitigation
measures and for proposing to ER for approval, designing and implementing
alternative or additional mitigation measures as appropriate.
