1.          BACKGROUND  

1.1       Hong Kong-Zhuhai-Macao Bridge (HZMB), Hong Kong Boundary Crossing Facilities (HKBCF) [now named as Hong Kong Port (HKP)] (the Project) is a designated project under the Environmental Impact Assessment Ordinance (EIAO). Pursuant to Section 10 of the EIAO, the Director of Environmental Protection granted an Environmental Permit (EP) No. EP-353/2009 to Highways Department (the Permit Holder) to construct and operate the Project.

1.2       According to Condition 4.1 of version K of the EP (No. EP-353/2009/K), the Permit Holder shall deposit with the Director of Environmental Protection three sets of a detailed Emergency Response Plan (ERP) on how to prevent oil and chemical spillage caused by traffic incidents on the carriageway from entering into the water body. The ERP shall be verified by the Independent Environmental Checker (IEC) as confirming to the recommendations contained in the EIA Report.

1.3       Section 9.9.4 of the EIA Report for HKBCF & Hong Kong Link Road (HKLR) discussed the accidental spillage. A copy of this section is enclosed in Appendix 1 of this ERP.


2.          objectives

2.1       This document presents the ERP to deal with oil and chemical spillage (hereinafter referred to as “chemical spillage”) due to vehicle accidents that may occur on the viaducts, at-grade roads and vehicle clearance plazas within the HKP during the operation stage of the HKP. The objectives of this ERP are to ensure that:

(1)          a timely and effective response to any spill incidents occurred on road surface and other adjacent areas contaminated by the spilled chemical on carriageways within the HKP;

(2)          the coordination of the relevant Government Departments to deal with the spill; and

(3)          minimal impacts to the aquatic environment and ecological system in the waterbody surrounding the HKP which is within the North Western Water Control Zone of the HKSAR.

2.2       The priorities for control of the spill are as follows:

(1)         The primary aim is to control the spreading of spill on the road surface on viaducts, at-grade roads and vehicle clearance plazas within the HKP and prevent release of spills into adjacent waterbody, either through road drainage systems or by other means; and

(2)         The secondary aim is to clean up the spill and re-open any affected area of the HKP to traffic as soon as possible.






3.          Chemicals of concern

3.1       There are wide varieties of chemicals. Oil, fertilizers, corrosive or poisonous chemicals which can pose serious threats to the ecology of the North Western Water Control Zone. This ERP deals with the general chemical spillage instead of restricting itself to only certain categories of chemicals.

3.2       Chemicals in liquid state or chemicals soluble in water are of most concern because there is a higher risk of these chemicals released into the sea through the drainage systems of the HKP.


4.          Master layout of HKBCF

4.1       The general layout of the HKBCF is shown on Drawing Nos. 60191048/MLP11/101 and 60191048/MLP11/102. There are viaducts, at-grade roads and vehicle clearance plazas within the HKBCF with vehicle movements.

4.2       The drainage systems on viaducts, carriageway and in the vehicle clearance plazas would discharge into the sea surrounding the HKP within the North Western Water Control Zone. In case of a vehicle accident on the carriageway, it may cause the spillage of chemicals that will have potential impacts to the water quality and ecology in the North Western Water Control Zone if the spillage is not dealt with properly.


5.         response organizations and emergency response plan

5.1       In a chemical spillage incident, a prompt action to prevent the spillage from releasing into the sea surrounding the HKP is the major task. A quick response time is therefore crucial in dealing with the spillage incident. The main response departments and the relevant emergency response plans being implemented are shown below. A flow chart depicting the procedures in dealing with chemical spillage incident on HKBCF, briefly listing out the respective responsibilities of various parties is shown in Appendix 2.


Hong Kong Police Force (HKPF)


5.2       The New Territories Regional Command and Control Centre (RCCC/NT) of HKPF operates 24 hours in parallel with Fire Services Communications Centre (FSCC) of Fire Services Department (FSD). Upon receiving the report of vehicle accident with, or with likelihood of, chemical spillage on the HKP, the RCCC/NT will immediately activate this ERP and inform the relevant Government Departments including but not limited to those Departments identified under this ERP to take immediate actions to deal with the (potential) chemical spillage.

5.3       HKPF will set up a Mobile Command Post to co-ordinate the road closure and clearing up operations.  All parties concerned might then liaise with the Command Post for updated information. 

5.4       As HKPF and FSD are usually the first emergency services to arrive at the scene, they will carry out a preliminary assessment as to the likelihood of chemical spillage from vehicle, and if spillage has occurred, the likelihood of the spill entering into the drainage systems of the HKP. HKPF should keep RCCC/NT informed of the seriousness of the incident and provide RCCC/NT with regular updated situation reports.

5.5      In the event of traffic congestion brought about by a chemical spillage incident, HKPF will inform the Mainland/Macao Authorities through the established border liaison channel for any incidents which may cause serious disruption to the operation of the HKP. They may request Mainland/Macao Authorities for assistance from Mainland/Macao as and where necessary.

5.6      HKPF will be the key member of the ad hoc chemical spillage response team comprising representatives of all relevant Departments to deal with (potential) chemical spillage from vehicle. The duties of the response team are as follows:

(1)            To assess the seriousness of the chemical spillage, the likelihood and the means to avoid the chemicals entering into the drainage gullies or the waters surrounding the HKP;


(2)            To coordinate between different Departments involved; and


(3)            To determine whether and what additional support and assistance from other Departments not included in this ERP should be called upon directly or through policy Bureaux.


5.7       Other duties of the HKPF in case of chemical spillage include:

(1)            Protect life and property;


(2)            Initiate a cordon of the area affected by the chemical spillage under the advice of FSD and EPD and implementing traffic management and control measures for people, vehicles or vessels at the scene. HKPF will also transport sawdust stored inside the weight-station in the HKP to the scene to control the spreading of any spilled chemical and to prevent the spillage chemical from entering into drainage systems on the carriageway;


(3)            Assist in evacuation of the affected area, if necessary;


(4)            Implement traffic management and control measures on all roads leading to the scene; and

Government Laboratory (GL)


5.16     When requested by FSD, GL will provide assistance in chemical identification in a chemical spillage incident and advise the characteristics of the chemical so as to help FSD and HKPF plan the operational strategy. If necessary, GL will send an officer to the scene to assist in locating / identifying the chemicals, analyse the levels of toxic substances at scene and/or provide advice to stabilise / handle / dispose of the chemicals.


Marine Department (MD)

5.17     MD is the designated authority for the clean up of oil spillage and floating refuse at sea.  When the chemical spill from a vehicle accident has been released from the HKP into the waters, MD will endeavor to regulate the marine traffic in and in the vicinity of the affected area, subject to available depth of water and a risk hazard assessment of the working environment confirmed that the prevailing environment is safe.  In case of oil spillage into the waters, the response actions from MD will follow the MOSRP, which has been developed to deal with oil spill and their potential hazard to the waters of HKSAR, in order to provide a timely response to oil spillages.

5.18     The other responsibilities of MD include:

(1)      Provide absorbents, booms and skimmers for controlling the spill at where and when practical and desirable; and


(2)      Monitor the spill situation and reporting extent of pollution.


In order to provide timely and effective responses to the incidents, MD would solicit assistance from Marine Police as necessary.

5.19     In principle, either MD or the Zhuhai/Macao counterpart will not be responsible for any cross border cleaning up of the oil spillage at sea, unless request is made by the governing side of the incident scene to the other side.  In such case, coordination will be through HKPF, who is the principal coordinating Department with the Zhuhai/Macao Governments through the established border liaison channel.

5.20     However, even if the oil spillage is confined to the waters of HZMB Main Bridge, MD will arrange a duty-officer to take charge of the clean-up operation at sea and render assistance when the situation warrants.  Moreover, the MD Patrol launch deployed at the scene/in vicinity  Its main duty is to provide traffic regulating.



Agriculture, Fisheries and Conservation Department (AFCD)

5.21     AFCD will advise on the protection of ecologically sensitive areas in the waters; provide assistance and comments on the methods for cleaning up the substances/wastes/chemicals washed ashore in the nearby Marine Parks, especially their ecological impacts as recommended by relevant authorities; and monitor the ecological conditions and assess the potential ecological/fisheries impacts at the likely affected ecologically sensitive areas.



Leisure and Cultural Services Department (LCSD)

5.22     If necessary, LCSD will arrange the removal of landed oil from gazetted beaches according to the MOSRP.


Food and Environmental Hygiene Department (FEHD)

5.23     In case of oil spillage incidents, FEHD will provide manpower to assist but limited to manual removal of non-contaminated refuse not classified as chemical or hazardous waste on non-gazetted beaches and foreshores that are without land access if necessary.  


District Office (Islands)

5.24     DO(Islands) will inform the relevant District Council member(s) and Village Representative(s) in case of chemical spillage incidents in the waters as necessary.


Owner of the Chemicals


5.25     In case of chemical spillage incidents, the responsibilities of the owner of the chemicals include the following:

(1)              Advise the type and characteristics of the chemicals; and


(2)              Remove the chemicals and those sand bags / absorbents which are soaked with chemicals, including the spilled chemicals on the carriageways of the HKP, in the waters and those washed ashore.


5.26     If the owner of the chemicals does not possess suitable plant and machinery for the removal, the owner could hire a contractor to do the job for himself, or alternatively the Government can do the job and then charge the owner accordingly. If the owner is reluctant to take action, relevant Government authorities could prosecute the owner according to the relevant laws of Hong Kong.



6.          emergency respoNse actions

6.1       In the event of vehicle accident on the carriageway of the HKP, the relevant Government Departments will implement the existing emergency response plans to deal with the incident.

6.2       It is important for the relevant Government Departments to confine the spill to be within the carriageway such that water quality and ecological impacts to the waters surrounding the HKP would be minimized.

6.3       At least 24 nos. dry sandbags will be stored at Highways Depot & Administration Building at the HKP to the southeast of the outbound vehicle clearance plaza and sawdust will be stored at the HKPF’s weigh-station at the HKP to the southwest of the outbound vehicle clearance plaza. The locations of HyD’s depot and HKPF’s weigh-station are shown in Drawing No. 60191048/MLP11/101. HyD will transport the sand bags and HKPF will transport the sawdust from their own storage locations to the scene respectively to control the spreading of any spilled chemical and to prevent the spilled chemical from entering into drainage system on the carriageway.

6.4       The operation guidelines to deal with the spill to minimize water quality and ecological impacts include:

(1)          Identify the type of chemicals if it would be poisonous / hazardous to human being in the vicinity through inhalation of / contact with them, or flammable / explosive which require immediate evacuation of the area;


(2)          Evacuate the area as necessary;


(3)          Stop the flow of spill from the source of the pollution;


(4)          Confine the spill to a limited area and prevent the spill from entering the road drainage system of the HKP;


(5)          Avoid spraying water or chemicals unless it is absolutely necessary. For oil spills to the waters, no oil dispersants should be used. For chemical spills, the measures to be taken will need to be decided case by case. Appropriate techniques and methods with careful study and assessment should be adopted.  AFCD, EPD and/or GL should be consulted as needed;


(6)          Remove the spilled chemical by using suitable equipment and materials, e.g. absorbent to absorb the oil on the road surface. The absorbent should be able to absorb oil material at a high ratio of oil to absorbent;


(7)          Dispose of the collected spill and the used absorbent as chemical wastes once the spill has been removed from the road surface;


(8)          Any flushing water (or other chemicals) for cleaning spilled chemical on the HKP should be retrieved by vacuum suction or equivalent means to suitable container for proper disposal. Flushing chemicals to the waters, either directly or via the road drainage system is strictly prohibited; and


(9)          Monitor the dispersion of the spilled chemicals in the waters.


6.5       Personnel responsible for the clean up operation should take safety precautions in accordance with the corresponding departmental guidelines and procedures.

6.6       According to the Height Restricted Areas and Special Areas for the Hong Kong Link Road and the Hong Kong International Airport Approach Restricted Areas under Fifth Schedule of Cap. 313A and Section 12 & 18B of Cap. 548F respectively, the relevant emergency responsible Departments should deploy their emergency teams and vessels in the vicinity to evaluate their vessel height in compliance with the height restriction under the Law.


7.          training and drill

7.1       In order to provide a prompt response to an emergency event, relevant Government Departments who are responsible for dealing with the spill incident must be familiar with the procedures and the operation of the essential equipment. Training should be provided to all designated personnel of all relevant Government Departments and other parties to deal with the spill incident on the HKP by individual party referring to its own standing practice that is currently in force in Hong Kong. The areas that should be covered in the training include:

(1)          Procedures to deal with spill incident


(2)          Ordinance and regulations related to chemical waste control


(3)          Awareness of chemical waste hazards and pollution


(4)          Roles and responsibilities


(5)          Precaution and safety measures


(6)          Spill clean up


(7)          Spill disposal


7.2       It is important to regular test-run to establish the effectiveness of this ERP. The aim is to ensure good coordination and prompt action amongst relevant Government Departments. Testing will take the form of an exercise or drill to practice responding to a spill on the HKP. The exercise is aimed to build the sense of teamwork and familiarity from relevant Government Departments. It makes the response more effective and efficient when an actual spill incident occurs. Details of the training and drill by each individual party should refer to its own standing practice that is currently in force in Hong Kong.
