Construction Programme for the Coming Months
7.1
The construction programme for the Project is shown in Appendix K.
7.2
Key issues to be considered in the coming month include:
·
Dust generated from land-based activities;
·
Wastewater/runoff generated on site;
·
Tree felling and transplantation;
·
Management of chemicals and avoidance of oil spillage; and
·
Noise from construction activity, such as breaking, excavation and PME
operation.
7.3 The following mitigation measures are required:
Air Quality Impact
·
To enclose and continuously spray water onto potential dusty operation, such as soil
nail installation, breaking, and handling of dusty material.
·
To water or cover the exposed surface/slopes, stockpiles
properly with impervious sheeting.
·
To water dry haul roads and unpaved works area sufficiently.
·
To conduct vehicle washing at every site egress.
·
To provide proper maintenance for machinery and vehicles on
site to avoid dark emission.
·
To investigate any other dust sources around the air sensitive
receivers.
·
To follow up any exceedance
caused by the construction works.
Construction Noise Impact
· To schedule noisy construction operation close to the NSR, such as backfilling and road paving at Slope 13, BPRW37, E05W, E03W and Slope 15.
· To follow up any exceedance caused by the construction works.
· To switch off equipment if not in use.
· To space out noisy equipment and move as far away as possible from the sensitive receivers.
· To deploy silent equipment.
· To erect noise barrier to alleviate noise impact.
Water Quality Impact
·
To carry out water quality testing in compliance with the Effluent
Discharge Licence.
·
To provide sufficient treatment for the wastewater/runoff
and groundwater prior to discharge.
·
To properly maintain the drainage systems on site.
Chemical and Waste Management
·
To remove waste from the site
regularly such that accumulation of waste materials or rubbish on site could be avoided.
· To avoid any improper storage and handling of chemical waste on site.
· To provide a sheltered and properly labelled chemical storage area; surround the area completely by concrete bunding; seal the gaps around the base of the storage area and properly lock the storage area.
· To provide drip trays with sufficient capacity for all diesel drums or chemical containers, if any, outside locked storage area.
· To consider reuse, recycle or return of Construction/ Demolition (C&D) material.
· To identify C&D material by packaging, labelling, storage, transportation and disposal in accordance with statutory regulations.
