Notes:

1. This Permit consists of three parts, namely, PART A (Main Permit), PART B (Description of Designated Project) and PART C (Permit Conditions). Any person relying on this permit should obtain independent legal advice on the legal implications under the Ordinance, and that the following notes are for general information only.

7. The Permit Holder may appeal against any condition of this Permit under Section 17 of the Ordinance within 30 days of receipt of this Permit.

Appendix A

Measures to Mitigate Environmental Impacts due to Site Run-off and Other Potential Water Pollution During Construction

(a) Surface Runoff

(i) Perimeter channels shall be provided at the site boundary to intercept storm-runoff from outside the site. Catchpits and perimeter channels shall be constructed in advance of site formation works and earthworks.

(ii) Surface run-off from the construction site shall be directed into adequately designed sand/silt removal facilities such as sand traps, silt traps, sediment basins, and oil interceptors at appropriate locations before discharge into storm drains. Channels, earth bunds or sand bag barriers shall be provided on site to properly direct stormwater to such silt removal facilities.

(iii) Earthworks final surfaces shall be well compacted and the subsequent permanent work or surface protection by shotcrete or hydroseeding shall be carried out immediately after the final surfaces are formed to prevent erosion caused by rainstorms.

(iv) Temporary access roads shall be protected by crushed gravels and exposed slope surfaces shall be covered with tarpaulin, similar fabric or hydroseeding to avoid weather erosion when rainstorms are likely.

(v) Manholes (including any newly constructed ones) shall always be adequately covered so as to prevent silt, construction materials or debris from getting into the drainage system, and to prevent storm run-off from getting into foul sewers. Discharges of surface run-off into foul sewers shall always be prevented in order not to unduly overload the foul sewerage system.

(b) Groundwater

(vi) Groundwater pumped out of wells, etc. for the lowering of ground water level in foundation construction shall be discharged into storm drains after being passed through appropriate silt removal facilities.

(c) General Construction Activities

(vii) At all parts of all works areas and construction sites, and throughout the full duration of the construction contract(s), debris and rubbish on site shall be handled and disposed of to avoid entering the water column and causing water quality impacts. Any washout of construction materials into the drainage system shall be via sediment traps.

(viii) Silt removal facilities, channels, oil interceptors and manholes shall be maintained with the deposited silt, grit and oil being removed at least once a week, and at the onset of and after each rainstorm to ensure that these facilities are functioning properly at all times.
