ES01
Civil Engineering and Development Department (hereafter referred as
¡§CEDD¡¨) is the Project Proponent and the Permit Holder of the Project Cross Bay
Link, Tseung Kwan O (hereinafter referred as ¡§the
Project¡¨) which is a Designated Project to be implemented under Environmental
Permit number EP-459/2013 (hereinafter referred as ¡§the EP-459/2013¡¨ or ¡§the
EP¡¨).

ES14
Due to wet season has approached, the Contractor was reminded that
all the works being undertaken must fulfill environmental statutory
requirements and to paid attention to water quality mitigation measures to
prevent surface runoff into nearby water bodies or public areas.
ES15
Construction noise would be the key environmental issue as Lohas Park Phase 4 & 6 were
already available for resident occupation. The noise mitigation measures such
as use of quiet plants and installation of temporary noise barrier at the
construction noise predominate area should be fully implemented in accordance
with the EM&A requirement.
