1 INTRODUCTION The City Rail Link (CRL) project comprises the construction, operation and maintenance of a 3.4 km underground passenger railway, running between Britomart Station and the North Auckland Rail Line in the vicinity of Mt Eden station. The works relating to this Emergency Spill Response Plan (ESRP) constitute part of the enabling works for the CRL. The works (the Project) involve the construction of twin rail tunnels within the Albert Street road corridor from Customs Street West to Wyndham Street. The tunnels will be constructed using a staged cut and cover method and are expected to take 21 months to complete. Figure 1 outlines the extent of works for the Project.

This ESRP has been prepared by AECOM New Zealand Limited (AECOM) and forms part of the Construction Environmental Management Plan (CEMP) for the Project. The ESRP specifically relates to conditions 52 and 96 of the resource consent conditions, R/REG/2014/5430 and 5436, respectively).

1.1

PURPOSE

Environmentally Hazardous Substances (EHS) will be present throughout the Project construction areas.

This ESRP relates to the management of spills of EHS’s and the prevention of adverse environmental effects to sensitive receivers.

This ESRP has been developed to set out spill management procedures for the Project works as required by the Project Industrial and Trade Activities Environment Management Plan (ITA EMP) (Appendix K of the CEMP) and the Project Chemical Treatment Management Plan (CTMP) (Appendix D of the Project Erosion and Sediment Control Plan (ESCP)). This ESRP forms an appendix to the Project CEMP (Appendix T) This ESRP has been prepared in consultation with a Community Liaison Group (CLG) prior to submission to Auckland Council (as per resource consent condition 19). A record of consultation outcomes is included in Appendix B.

1.2

3.

Piling and road deck construction within the Customs Street Intersection

4.

Trench Excavation, including using shotcrete and Rock Dowelling

5.

Construction and waterproofing of the rail tunnels

6.

Backfilling of the trench, including Pile Cap Demolition and construction of the new road pavement

A range of supporting activities will also occur in the Project Construction Support Areas (CSA) 4, 5 and 6. Further detail on these activities is provided in the Project ITA EMP. The locations of the CSAs are shown in Appendix A of this ESRP. Chemical treatment will be required to assist with flocculation and settlement of sediment entrained in surface water runoff and groundwater on the site. The location of water treatment devices is identified in the Project ESCP (Appendix I of the Project CEMP).

Stormwater from the Project construction areas will be treated as per the Project ESCP and runoff from the CSA’s will be managed as set out in the Project ITA EMP.

3 SITE ACTIVITIES 3.1

SITE DESCRIPTION

The Project comprises Active Construction Zones (ACZ) D and E (Figure 2), which were identified during the CRL Britomart to Wyndham enabling works consenting process to delineate construction methodology for different work areas. Additionally, a range of supporting activities will occur in the Project CSAs. Drawings in Appendix A show the proposed site layout across the Project area, including the location of hazardous substance storage, spill kits, equipment storage and stockpile areas within CSA 4/5 and CSA 6.

Spillages within the ACZs will be managed and cleaned up on site and any contamination of rain water or groundwater within the trench will be treated as per the ESCP prior to release or disposal.

Spillages within the CSAs will be managed and controlled within the CSA and spill risk will be managed through structural and procedural controls. In the event that a spill incident exceeds these controls, it will be managed in accordance with the provisions of this ESRP. Figure 2 Location of ACZs D and E

Sections 4.1 to 4.5 of this ESRP outline the relevant spill response procedures for the different spill size/type. Figure 3 provides a graphical representation of these procedures.

4.1

SMALL SPILLS OF LESS THAN 20L

Small spills have been defined as those less than 20L since this is the volume which triggers contact through the Auckland Council Pollution Hotline. Spills of this volume are deemed “insignificant” incidents in accordance with Table 11 of the Project CEMP, provided that they are contained within established controls and are not released from site. They will be managed on site as set out below: •

Based on visual inspection from a safe distance, estimate volume of spill and identify substance.

If access is available protect any nearby drains to prevent spill from entering.

•

Refer to SDS and determine if it is safe to contain and clean up without specialist help. If it is safe to do so put on appropriate Personal Protective Equipment (PPE), stop the spill if possible and use on site spill kit to contain and clean up spillage.

CONNECTUS PROJECT NO. 2719 CITY RAIL LINK LIMITED

PAGE 13 OF 20

EMERGENCY SPILL RESPONSE PLAN Doc No:025-Y032-27190 REVISION: 05 DATE: 24-July-2017

•

Contain the spill using sand bags, absorbent booms or powders. Allow the spill to absorb into the spill clean-up materials.

•

Decontaminate PPE in a manner that ensures wash waters do not enter the stormwater system or the receiving environment.

•

Report incident to supervisor and Environment and Sustainability Manager (ESM) and log in incident recording system as required under Section 4.3.21 (Table 11) of the Project CEMP.

•

Dispose of spill residual and clean-up materials in labelled container and place in specified waste chemical and oils storage area.

4.2

MODERATE SPILLS IN EXCESS OF 20L

Moderate spills are determined to be between 20L and 39L. An incident that breaches established controls but with no effect beyond the site boundary would be determined as a “minor” incident, whilst those that breach consent or cause environmental effects beyond the site boundary are deemed to be “serious”.

The procedures to be followed are as above if the spill can be safely contained on site. If this is not possible then the emergency services or specialist spill response contractor will be required to clean up the spill as set out in section 4.3 below.

All spills of Environmentally Hazardous Substances over 20 litres that have entered the stormwater system, a water-body or have contacted unsealed ground, shall be reported immediately to the Auckland Council’s 24-Hour Pollution Hotline The incident will be logged and reported as set out in Section 4.3.21 (Table 11) of the Project CEMP.

4.3

LARGE SPILLS IN EXCESS OF 40 L

Spills in excess of 40L (one 10-gallon drum) would be deemed a serious incident. The following procedure will be followed.

•

Carry out a visual inspection from a safe distance to identify the spilt substance, the approximate volume and assess if it is safe to contain the spill.

•

Review the SDS. Spills of toxic, oxidizing or flammable substances in excess of 40L (10-gallon drum) will be referred to specialist spill response contractors and if required Emergency Services.

•

Put on appropriate PPE.

•

Evacuate the immediate area.

•

The incident will be reported immediately to the site supervisor and as soon as possible to the Auckland Council Pollution Hotline.

•

Whilst waiting for the specialists, cover stormwater drains where possible and prevent release from migration of the spill using spill containment booms or sand bags if safe to do so.

•

Decontaminate PPE in a manner that ensures wash waters do not enter the stormwater system or the receiving environment.

•

Following clean up either the specialist contractor will remove the material from site or if safe to do so may contain the spilt material and relocate to the specified waste chemical and oil storage area for later disposal.

•

Report incident to supervisor and ESM and log in incident recording system as required under Section 4.3.21 (Table 11) of the Project CEMP.

EMERGENCY SPILL RESPONSE PLAN Doc No:025-Y032-27190 REVISION: 05 DATE: 24-July-2017

4.4

DRY MATERIAL SPILLAGE

It is possible that dry materials such as cement and grout materials may be spilled on site. These will be cleaned up on site as quickly as possible using the following procedure:

4.5

•

Carry out a visual inspection from a safe distance to identify the spilt substance, the approximate volume and assess if it is safe to contain the spill.

•

Review the MSDS and adopt appropriate PPE.

•

Cordon off the area to prevent vehicle or pedestrian access to the spill and therefore prevent tracking of contaminants across the site.

•

Protect/cover any downstream stormwater catchpits to prevent the material entering the stormwater system.

•

As soon as possible, clean up the spillage using a spade or similar and place the waste material in a labelled container for safe removal from site.

•

Following clean up relocate to the specified waste chemical and oil storage area for later disposal.

•

Decontaminate PPE in a manner that ensures wash waters do not enter the stormwater system or the receiving environment.

•

Report incident to supervisor and ESM and log in incident recording system as required under Section 4.3.21 (Table 11 of the Project CEMP).

EVACUATION

Spillage of large quantities of flammable liquids, corrosive substances, the release of a hazardous gas or the ignition of a flammable substance will require urgent evacuation of the immediate area and any area immediately down wind or downstream of the escape.

The site supervisor and emergency services will be contacted immediately.

Comment I'm surprised that argon is listed as an environmental hazard.

It is an inert gas, nontoxic but heavier-thanair so venting of a significant quantity might cause a hazard to workers in a confined space such as an excavation. With a stirring breeze, it will be harmlessly dissipated in the atmosphere. It doesn't seem feasible to "contain" it.

5L seems an insignificant quantity in terms of hazard

Resolution Table 2 in Section 3.2 Hazardous Substances has the following change made: Argon has been removed from the indicative list of EHS stored on site.
