Annex A: Mitigation Measures to Minimize Potential Water Quality Impacts
附件A:盡量減低對水質的潛在影響的緩解措施
Site run-off and drainage shall be prevented or minimized in accordance with the guidelines stipulated in the Environmental Protection Department's Practice Note for Professional Persons, Construction Site Drainage (ProPECC PN 1/94). The following management practices shall be followed:
必須根據環境保護署供專業人士參考的守則《ProPECC PN 1/94》(關於建築工地排水),防止或盡可能減少工地排出的地面徑流或污水。下列的管理措施應予遵守。
1. Demolition Site Run-off and Surface Water Drainage 清拆工地內地面徑流及地面水的排放
1.1 Exposed soil areas shall be minimized to reduce the potential for siltation, contamination of run-off, and erosion. Run-off related impacts associated with demolition work and other general activities shall be controlled through the use of appropriate mitigation measures which include: 應盡可能減少泥土外露的範圍,以降低淤泥堆積、地面徑流受污染及造成沖刷的可能性。就清拆工程及其他一般活動地面徑流相關的影響,應採取恰當的緩解措施,方便控制情況,這些措施包括:
1.2 The boundaries of critical site areas shall be marked and provided with protective measures to control site run-off. Temporary channels shall be provided to facilitate run-off discharge into the appropriate watercourses, via a silt retention pond. Permanent drainage channels shall incorporate sediment basins or traps and baffles to enhance deposition rates.
1.3 All temporary and permanent drainage pipes and culverts provided to facilitate run-off discharge shall be adequately designed for the controlled release of storm flows. All sediment traps shall be regularly cleaned and maintained. The temporarily diverted drainage shall be reinstated to its original condition when the demolition work has finished or the temporary diversion is no longer required.
1.4 Sand and silt in the wash water from the wheel washing facilities, which ensure no earth, mud and debris is deposited on roads, shall be settled out and removed before discharging the used water into storm drains. A section of the road between the wheel washing bay and the public road shall be paved with backfall to prevent wash water or other site run-off from entering public road drains.
1.5 Oil interception facilities shall be provided in appropriate areas in the drainage system, where oil spills may occur, and regularly emptied to prevent the release of oil and grease into the storm water drainage system after accidental spillages.
2. General Demolition Activities 一般清拆活動
2.1 Debris and rubbish on site shall be collected, handled and disposed of properly to prevent such material from entering the water column and causing water quality impacts.
2.2 All fuel storage areas shall be provided with locks and be sited on sealed areas, within bunds of a capacity equal to 110% of the storage capacity of the largest container to control spilt fuel oils.
2.3 All site boundaries shall be well maintained and good site practice shall be observed to ensure that litter and fuels are managed, stored and handled properly.
3. Sewage Effluent 污水
Demolition workforce sewage discharges on site shall be connected to the existing sewer or sewage treatment facilities where possible. If the demolition works result in the loss of connection to the sewerage system, adequate portable chemical toilets will need to be provided by a licensed contractor who will be responsible for the proper maintenance of these facilities.
Annex B: Mitigation Measures to Minimize Potential Risk to Life
附件B:盡量減低危害生命的潛在風險的緩解措施
The following recommendations shall be implemented, as risk reduction measures, to ensure that the explosive demolition of Tsing Yi Power Station chimneys is carried out within the Hong Kong Risk Guidelines.
1. The nearest Mobil oil tank shall be emptied for the duration of the felling.
2. Fire detection (heat/flame) and fire-fighting foam systems on all oil tanks and bunds shall be fully tested prior to the demolition exercise and be ready for remote activation by oil terminal staff.
3. Water sprays on LPG spheres shall be fully tested prior to the demolition exercise and ready for remote activation by oil terminal staff.
4. A 3-chimney height exclusion zone shall be maintained to minimize the chance of ejecta or debris hitting any spectators.
5. No road tankers containing liquid LPG or oil products shall be present within the 3-chimneys height exclusion zone.
6. Marine tankers shall be well beyond the 3 chimney height exclusion zone (suggest 1km unless empty).
7. The processes on the Mobil and ESSO sites (all vessels and pipework) shall be fully isolated during initiation.
8. Initiation shall not be carried out if high or gusting winds are expected, to avoid the possibility of the chimney falling in an unplanned direction or at an unplanned time.
9. Initiation shall not be carried out if heavy rain has occurred, as this tends to increase the likelihood and effect distance of landslides.
10. Boats in the area shall be kept well beyond the 3-chimney height exclusion zone.
11. The ESSO LPG spheres shall be reduced to less than 200 tonnes per sphere during the felling process.
12. The independent technical review of the EIA Report has highlighted the need for the demolition contractor to have in place a robust safety management system for both the explosive and manual methods. This would include a system for identification of hazards similar to the SWIFT technique used in the Project Profile but applied using an expert multi-disciplinary team (including the demolition contractors and for the explosive method, the oil companies).

在開始解除煙囪的運作之前,許可證持有人須先向署長存放5份在環評報告所列出的廢物管理計劃,以避免或減低因產生廢物而可能導致的影響。廢物管理計劃須清楚列述廢物處置條例或其他污染管制條例所未能涵蓋的廢物管理措施。廢物管理計劃必須妥當實施。
必須妥善實施為工程項目所擬備及為反映工程項目簡介的拆卸方法而修訂的環境監察及審核手冊其中列述的環境監察及審核計劃。環境監察及審核手冊行動計劃所載述的行動,必須按照該行動計劃內的時限或署長同意的時限執行。
必須待埃索石油香港有限公司(青衣油庫)[下稱「埃索」]的3個石油氣球缸中每個的存氣量低於200公噸時,才可動工拆除煙囪。許可證持有人須與埃索聯絡,以確定在哪段時期可將石油氣存氣量降減至所需水平,並相應安排拆除煙囪的時間。許可證持有人必須至少在動工拆除前一星期將煙囪拆除時間知會署長。
許可證持有人必須在即將動工拆卸之前,與埃索安排測試所有裝置在埃索青衣油庫的滅火系統。倘若滅火系統明顯出現故障,須將拆卸工程押後至滅火系統能完全發揮效能之後。
許可證持有人必須與埃索安排,在動工拆卸前停止在油庫內進行一切非必要的工作,及在拆卸期間,將所有非必要人員撤離至安全地區。
許可證持有人須與埃索安排,在動工拆卸前使所有石油氣運載車(空車除外)駛離油庫,而在拆卸進行期間更須駛離禁區之外。
許可證持有人須與埃索安排,當拆卸煙囪工程進行時阻止任何躉船、油船或任何其他船隻在埃索的碼頭或海堤裝載石油氣或轉運石油氣以儲存。
許可證持有人須與埃索及香港美孚石油有限公司(青衣油庫)[下稱「美孚」]聯絡,以便實施本許可證附件B所附載風險評估中的建議緩解措施。
拆卸煙囪的工程必須在這些建議緩解措施全部實施後才可進行。許可證持有人須向各有關方面(包括埃索及美孚)提交證明已實施建議緩解措施的書面確認。
本許可證所訂的特別條件,並不使許可證持有人或工地/地盤的任何人可以免除遵守下列條例的規定或預防措施的責任:氣體安全條例(第51章);消防安全(商業處所)條例(第502章);危險品條例(第295章);建築物條例(第123章);與公共生或安全事宜有關的任何其他條例。
本環境許可證共有3部,即:A部(許可證主要部分);B部(指定工程項目的說明);及C部(許可證條件)。
許可證持有人可根據條例第13條的規定向署長申請更改本環境許可證的條件。許可證持有人須將經修改的許可證,替換在建築工地/地盤內展示的原有許可證。
承擔解除指定工程項目運作的整項或部分工程的責任的人,在承擔解除指定工程項目責任之前,可根據條例第12條的規定向署長申請新的環境許可證。
根據條例第14條的規定,署長可在規劃環境地政局局長的同意下暫時吊銷、更改或取消環境許可證。該許可證必須從建築工地/地盤除下,不再展示。
如果本許可證在解除運作期間取消或交回,則在繼續進行解除指定工程項目運作之前,必須先根據條例規定取得環境許可證。根據條例第26(1)條的規定,任何人在沒有環境許可證的情況下解除指定工程項目的運作,即屬犯罪。
應該標明主要工地的界線,並採取保護措施,控制工地的地面徑流。提供臨時的渠道,使地面徑流經淤泥沉積池排入適當的水道。永久性的排污渠道須設有集泥池∕截泥器及柵極,可提高淤泥沉積率。
為便排放徑流而設的所有臨時及永久性排水渠及暗渠,其設計應足以使雨水有控制地排放。截泥器必須定時清理維修。此外,在清拆工程完成後,或毋須再臨時分流排水時,應確保臨時分流的排水系統恢復原來狀態。
清洗車輪設施用以確保泥土及砂礫不會在路面積聚,因此,在清洗車輪設施的洗滌水排入雨水渠前,應預先隔濾洗滌水,除去當中的泥沙及淤土。在清洗車輪工作台與公共道路之間的一段路面,應該鋪上回填料,以防洗滌水或其他工地的地面徑流流入公共道路的排污渠。
應在排水系統的適當地點(即可能漏油的地方)裝置截油設施,並且定時抽空截油設施,以防在意外漏油後,油類及油脂流入雨水渠。
應該適當收集、處理和棄置工地的砂礫及廢物,以防流入水柱內並對水質造成影響。
存放燃油的地方應該上鎖,設於封閉區域內,外圍須加設堤圍,堤圍的貯存量應相當於最大容器存量的110%,以抑控泄漏燃油。
工地界線必須標明,並遵守良好的作業守則,以確保妥善管理、存放和處置垃圾和燃料。
在可行情況下,清拆工人在工地排放的污水,應接駁至現有的污水管或污水處理設施。如果因為進行清拆工程而不能接駁排污系統,應委託持牌承辦商提供足夠的便攜式化學化糞廁所,並由該名承辦商負責妥善維修這些廁所。
應執行下列建議,作為減低風險的措施,確保以爆破形式拆卸青衣發電廠的煙囪時,能符合《香港風險指引》的規定。
在進行拆卸期間,應把最接近的美孚油缸放空。
進行拆卸前,應全面測試所有油缸和範圍內的火警探測(新熱度/火焰)及滅火泡沫系統,確保該系統能由油站職員遙控啟動。
進行拆卸前,應全面測試石油氣球缸的灑水裝置,確保能由油站職員遙控啟用。
應保持一個相等於3枝煙囪高度的限制區,以防噴出物或碎片擊中周圍的人。
在該3枝煙囪高度的限制區內,不可停泊載有液化石油氣的運油車或放置任何燃料產品。
運油船應遠離該3枝煙囪高度的限制區(建議保持1公里距離,除非是空船)。
在進行拆卸期間,應完全隔離美孚及埃索油站內的操作工序(所有油缸和管道裝置)。
如果預期有大風或狂風,便不應進行拆卸工作,避免拆掉的煙囪會朝非預計的方向或在某個不能預計的時間倒下。
如果下大雨,便不應進行拆卸工作,否則會增加發生山泥傾卸的機會及擴大受山泥傾卸影響的有效距離。
區內的船隻應保持在遠離3枝煙囪高度的限制區外。
在進行拆卸期間,埃索石油氣球缸存氣量應減少至每缸不多於200公噸。
環境影響評估報告的獨立技術檢討已特別指出不論是用爆破方法或人手控制方法,拆卸承辦商都要採取穩健的安全管理系統。這會包括一個可以找出危險的系統,與工程項目簡介中使用的SWIFT技術類似,而這項技術是由一支包含多門專業的專家小組所應用(包括拆卸承辦商,而爆破方法則包括油公司)。
