1             INTRODUCTION

 

1.1         Project Descriptions

 

Gammon Construction Limited (GCL) has been commissioned to design and construct the Contract No. HY/2012/07 íV Tuen Mun Chek Lap Kok Link íV Southern Connection Viaduct Section for the Highways Department (HyD) of the Government of the Hong Kong Special Administrative Region (HKSARG).  The Works to be executed comprise the construction of a dual 2-lane elevated carriageway between the HZMB HKBCF and North Lantau Highway (NLH) with associated slip roads, as well as modifications and realignment of sections of the NLH and Cheung Tung Road at North Lantau, and associated works.

 

2             PURPOSE OF THE PLAN

 

The Spill Response Plan (SRP) has been developed in accordance with Condition 2.7 of the Environmental Permit (EP-354/2009/A) for the Highways Department Contract namely Contract No. HY/2012/07 íV Tuen Mun Chek Lap Kok Link íV Southern Connection Viaduct Section.

 

The SRP shall describe the actions to be taken in the event of accidental spillage of oil or other hazardous chemicals from construction activities including vessels operating for the Contract, with specific provisions for protecting marine ecology and the Chinese White Dolphins.

 

3             GENERAL PRECAUTIONS

 

In order to minimize the possibilities of accidental spillage of oil or other hazardous chemicals at the construction site and on vessels, the following precautionary measures will be implemented on site as far as possible:

íP                The storage areas of chemicals and chemical wastes on land should be located remote from the coast and any other water bodies as far as practicable.

íP                Use drip trays for storage containers of chemical oil fuel tanks and / or generators.

íP                Reduce the danger of stacked containers of oil or chemicals falling.

íP                Provide tightly closed lids so as to avoid leakage of chemicals and chemical waste especially if accidentally knocked over.

íP                Store chemicals and chemical waste in separate storage areas.

íP                Inspect the storage area regularly to detect if any leakage has occurred or if any of the containers become defective on a regular weekly basis.

íP                Use suitable containers, which are resistant to the stored chemicals or the chemical waste so as to prevent leakage.

íP                Label the storage containers and the chemical tanks according to the EPDíŽs ížCode of Practice on the Package, Labelling and Storage of Chemical Wastes LabellingíĘ.

íP                Provide adequate ventilation in the storage area as necessary.

íP                Prohibit open flames and smoking near the chemical storage and fuel storage areas.

íP                Store large and heavy containers on the floor as far as possible and avoid storing these containers higher than 0.75m above the floor level (storage in vessel / barges are exclusive).

íP                Keep all chemical, chemical waste and fuel oil storage containers below eye level for easy inspection.

íP                Provide adequate space for safe and easy handling and inspection of the containers.

íP                Maintain an up-to-date log of all chemicals, chemical waste and fuel oil stored at site.

íP                Separate incompatible chemicals from one another.

íP                Keep the ingress to the chemical storage area locked and restrict access.

íP                Provide a bucket of dry sand and a suitable fire extinguisher in the storage area.

 

4             TRANSFER & TRANSPORT PRECAUTIONS

 

In order to minimize the chance of accidental spillage occurring during the transportation of chemicals or containers of chemicals to and from the construction site, some precautionary measures will be implemented on site. These precautions are subject to site conditions and constraints. These are:

íP                Use a suitably sized container so as to avoid overfilling.

íP                Use pumps to transfer chemical waste instead of manually pouring them.

íP                Provide a containment structure able to hold any chemical or chemical waste that is accidentally spilled.

íP                Use proper, safe and suitably labelled containers.

íP                Use suitable carrying equipment to transfer the chemical and chemical; waste containers from one location to another.

íP                Only employ and use suitably licensed, trained and responsible chemical waste collection persons to carry out the transportation requirements.

íP                Small amount of cement will be used for grouting back of sampling core. However, cement bags will be stored up with bunding and covered by tarpaulin all the time when over 20 bags per a location. Spillage would be confined by boom or silt curtain to avoid further dispersion.

íP                Bentonite will be stored in a silo and the capacity to accommodate 110% of the volume of bentonite or 20% by volume of bentonite stored. Connection pipes shall be check and maintenance frequently to prevent accidental spillage. Spillage would be confined by boom or silt curtain to avoid further dispersion.

 

5         GENERAL RESPONSE TO SPILL INCIDENTS

 

The general response to the spill shall be carried out to minimize the amount of oil or hazardous chemicals to the marine environment.  The location of the spill is also a consideration.  The general responses are classified in difference scenarios and they are illustrated in a flowchart as shown in Appendix A.

 

 

 

5.1         Scenario 1 íV Spill contained on the deck of a vessel or on land

 

Workers should be made aware of the emergency telephone numbers, locations of emergency showers, location of spill kits and emergency evacuation routes.  Medical emergency response should also be undertaken whenever necessary.  The response actions to an incident should include, but not limit to, the following steps:

1.       Immediately inform the Emergency Team of the spill incident occurring.

2.       Take all possible measures to reduce or stop the spillage, such as shut off the valve.

3.       Provided it is safe to do so, the area containing the spill shall have forced ventilation installed in order to make a safe spillage condition.

4.       The Emergency Team shall be responsible for organizing the manpower to identify the spill source and stop or cease it. 

5.       The Emergency Team as the assigned person shall equip all people involved in the clean-up works suitable personal protective equipment prior to the removal of any leaked chemical or chemical waste.

6.       If possible and practical, the spilt chemical shall be put back into the containers of origin.  Otherwise a suitable material like dry sand or sawdust shall be used to absorb the leakage.

7.       Any contaminated sand / sawdust / other materials shall be collected and put into black plastic bags and shall be clearly labelled as "chemical waste".

8.       All collected chemical waste shall be placed in an area designated for chemical waste storage.

 

5.2         Scenario 2 íV Spill into the Marine Environment

 

This type of spill is considered the most serious in terms of the possibility of causing impact to the local cetacean community and other marine organisms. The notification system is separated into two scenarios, as determined by the area of spillage of 100m2. 

 

Before commencement of marine works, sufficient standard Spill Kits will be available on site up to control marine spillage of up to 100m2 in size.  The standard Spill Kits includes items such as pads, pillow and Secondary Oil Containment (SOC).  SOC is used to enclose the spillage area to contain the spillage spreading outside of the SOC. There are 30 nos. of SOC to be available on site. The pads and pillow are used for absorbing and removing the spillage within the SOC.  Standard spill kits are attached in Appendix B.

 

It is the responsibility of all persons observing the spill to report this immediately to their immediate supervisor who shall inform the Emergency Team Leader. A site agent in Emergency Team shall be assigned to lead a working team and to deploy the Spill Kits to the spillage site. Depending on the scale of the spillage area of 100m2, there are two scenarios of spill response procedures to be applied.

 

5.2.1     Scenario 2a íV Spillage area exceed 100 m2

íP                Emergency Team shall inform all parties such as Environmental Team (ET), Supervisory Officer Representative (SOR), Highways Department (HyD), Independent Environmental Checker (IEC), Marine Department (MD), Fire Services Department (FSD), Agriculture, Fisheries and Conservation Department (AFCD), Environmental Protection Department (EPD) and the GCL emergency team members immediately.  The contacts of the other concerned parties tabulated are in Appendix C.

íP                The Emergency Team shall be responsible for organizing the manpower to identify the spill source and stop or cease it.

íP                The Emergency Team is the assigned persons who shall equip with suitable personal protective equipment to remove any leaked chemical or chemical waste.

íP                The spillage area shall be contained by using secondary oil containment (SOC). 

íP                Pads and pillow of the spill kit shall be applied to absorb and remove the spillage within the SOC.  They will be collected by disposal bags as part of the spill kits item.

íP                The used spill kits will be treated, stored and disposed of as chemical waste according to the necessary procedures.

íP                An incident report will be submitted to the SOR & ENPO/IEC within 2 working days.

 

5.2.2     Scenario 2b íV Spillage area within 100 m2

íP                The Emergency Team shall inform the parties such as SOR, ENPO/IEC, ETL and the GCL emergency team members.

íP                The Emergency Team shall be responsible for organizing the manpower to identify the spill source and stop or cease it. 

íP                The Emergency Team is the assigned persons who shall equip with suitable personal protective equipment to remove of any leaked chemical or chemical waste.

íP                The spillage area shall be contained by using secondary oil containment (SOC).

íP                Pads and pillow of the spill kit shall be applied to absorb and remove the spillage within the SOC.  They will be collected by disposal bags as part of the spill kits item.

íP                The used spill kits will be treated, stored and disposed of as chemical waste according to the necessary procedures. 

íP                An incident report will be submitted to the SOR & ENPO/IEC within 2 working days.

 

5.2.3     All Reasonable Actions to Keep Dolphins Away from Contaminated Areas

 

The use of booms is an effective containment method and can also act as a barrier to dolphins. Deployment of such with concomitant visual and acoustic observations is appropriate for small and controllable spills that can be dealt with in the short term.

 

In the event of larger spills, GCL will provide and deploy physical barriers (such as silt curtains, 1 no. , approx. size in 10m x 3m) would be an effective means of keeping dolphins out of the contaminated area until such times as the area was free of contamination. The physical barrier will be available on working barge or loading platform.

 

If dolphins were found within spillage areas, Dolphin Specialist or his delegates (refer to Table 1) will be consulted via phone call first for this case. He/she will be on-site to handle such incidence within 2 hours.

 

6         EMERGENCY TEAM

 

6.1         Team Structure

 

An emergency team shall be established for the Contract in order to dealing with spillage cases promptly.
