Appendix A

Measures to Mitigate Environmental Impacts from Site Run-off and Drainage

To mitigate the environmental impacts from site run-off and drainage, the following shall be implemented:

(a) adequate maintenance of drainage systems shall be provided to prevent flooding and overflow during the construction period;

(b) the boundaries of areas of earthworks shall be marked and surrounded by dykes for flood protection during the construction period. Temporary ditches should be provided to facilitate runoff discharge into the appropriate watercourses, via a silt retention pond. Permanent drainage channels should incorporate sediment basins or traps and baffles to enhance deposition rates. The design of efficient silt removal facilities should be based on the guidelines in ProPEC Practice Note 1/94 issued by the Director of Environmental Protection;

(c) construction works shall be programmed to minimize surface excavation works during the rainy season (April to September). All exposed earth shall be stabilized as soon as possible after earthworks have been completed, or alternatively, within 14 days of the cessation of earthworks where practicable. If excavation of soil cannot be avoided during the rainy season, or at any time of year when rainstorms are likely, exposed slope surfaces should be covered by tarpaulin or other means;

(d) sediment tanks of sufficient capacity constructed from pre-formed individual cells of approximately 6 to 8 cu.m. capacity shall be used for settling surface runoff prior to disposal during the construction period. The system capacity shall be flexible and able to handle multiple inputs from a variety of sources and particularly suited to applications where the influent is pumped;

(e) open stockpiles of construction materials (e.g. aggregates, sand and fill material) of more than 50 cu.m. shall be covered with tarpaulin or similar fabric during rainstorms. Measures should be taken to prevent the washing away of construction materials, soil, silt or debris into any drainage system;

(f) manholes, including newly constructed ones, shall always be covered and sealed so as to prevent silt, construction materials or debris being washed into the drainage system and storm runoff being directed into foul sewers during the construction period. At any time of year when rainstorms are imminent or forecast, actions shall be taken in accordance with the ProPECC Practice Note 1/94 issued by the Director of Environmental Protection. Particular attention should be paid to the control of silty surface runoff during storm events, especially for areas located near steep slopes;

(g) oil interceptors shall be provided in drainage systems and oils and grease shall be regularly removed to prevent the release of oils and grease into storm water drainage systems after accidental spillage during the construction period. The interceptors should have a bypass to prevent flushing during periods of heavy rain;

(h) all vehicles and plant shall be cleaned before leaving a construction site to ensure no earth, mud, debris and the like is deposited by them on roads during the construction period. An adequately designed and located wheel washing bay should be provided at every site exit and wash-water should have sand and silt settled out and removed at least on a weekly basis to ensure the continued efficiency of the process. The section of access road leading to, and exiting from, the wheel-wash bay to the public road should be paved with sufficient backfill toward the wheel-wash bay to prevent vehicle tracking of soil and silty water to public roads and drains;

(i) sediment shall be intercepted before it enters into modified sections of culverts. Sediment traps should be installed both upstream and downstream of any modified culvert sections in order to minimise the sediment loading in these culverts. Vortex tube site traps shall also be installed to provide continuous extraction of sediment within the modified sections of the culverts;

(j) temporary and permanent drainage pipes and culverts shall be provided to facilitate runoff discharge during the construction period. The temporary and permanent drainage pipes and culverts should be adequately designed for the controlled release of storm flows. All sediment control measures should be regularly inspected and maintained to ensure proper and efficient operation at all times and particularly following rain storms. Temporarily diverted drainage should be reinstated to its original condition when construction work has finished or the temporary diversion is no longer required; and

(k) discharge and surface runoff contaminated by materials from any concrete batching plant shall be diverted to neutralisation tank to reduce acidity and the treated discharge should be connected to silt trap to remove suspended solids before disposing to sewage system.

Appendix B

Measures to Mitigate the Water Quality Impacts During Tunneling

To mitigate the water quality impacts during tunneling, the following shall be implemented:

(a) the cut-and-cover tunneling work should be conducted segment by segment to limit the amount of construction runoff generated in the areas particularly during the wet season (April to September)

(b) temporary open storage of excavated materials used for backfill on site should be covered with tarpaulin or similar fabric during rainstorms. Any washout of construction or excavated materials should be diverted through appropriate sediment traps before discharge to stormwater drainage system. Ground water pumped out of tunnels should be discharged into the drainage channels which incorporate sediment traps to enhance deposition rates and to remove silt; and

(c) spent bentonite slurries or other grouts used in diaphragm wall construction and in a separate slurry collection system shall be collected, and reconditioned and reused wherever practicable.

Appendix C

Measures to Mitigate Water Quality Impact During Dredging and Other Construction Activities

To mitigate the water quality impact during reclamation work and other construction activities:

(a) any mechanical grabs shall be designed and maintained to avoid spillage and sealed tightly while being lifted during the construction period. For dredging of contaminated mud, closed watertight gabs shall be used;

(b) silt curtains shall be deployed around dredging areas during the dredging and filling operation;

(c) no foam, oil, grease, sum, litter or other objectionable matter shall be caused to be present on the water within the site or dumping grounds during the construction period;

(d) debris and rubbish on site shall be collected, handled and disposed of properly to avoid entering the water column to cause water quality impacts;

(e) to prevent spilled fuel oils, all fuel tanks and storage areas shall be provided with locks and located on sealed areas, and within bunds of a capacity equal to 110% of the storage capacity of the largest tank; and

(f) construction work force sewage discharges on site shall be connected to existing sewer or sewage treatment facilities. Portable chemical toilets shall be provided to construction workers.
