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 Industrial and Trade Activities Environmental Management Plan (ITA EMP) 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 33 months to complete. Figure 1 outlines the extent of works for the Project.

This ITA EMP has been prepared by AECOM New Zealand Limited (AECOM) and forms part of the Construction Environmental Management Plan (CEMP) for the Project. The ITA EMP specifically relates to conditions 95 – 104 of discharge permit R/REG/2014/5436.

1.1

PURPOSE OF THE INDUSTRIAL AND TRADE ACTIVITIES EMP

This ITA EMP has been prepared to manage the ITAs that will be undertaken in Construction Support Areas (CSAs) 4, 5 and 6 a n d t h e which are associated with the construction of the Britomart Station to Wyndham Street (Britomart to Wyndham) section of the City Rail Link (CRL) project. It provides a framework for the effective management of stormwater discharges from these CSAs - i.e. the Northern Compound (CSA 4 and CSA 5) and the Southern Compound (CSA 6), and documents the management and operational systems employed by Connectus to ensure that the environmental objectives of the site are met. The Project site will be operated and managed in accordance with this ITA EMP at all times.

The Project comprises Active Construction Zones (ACZ) D and E (refer Figure 2), which were identified during the CRL Britomart to Wyndham enabling works consenting process to delineate construction methodology for different work areas. This ITA EMP includes the ACZs, contaminated stormwater generated in the ACZs will be led to the construction trench and pumped out of the trenches for treatment prior to discharge to the stormwater or sewer system or managed as part of the erosion and sediment control processes (refer to the Project Erosion and Sediment Control Plan (ESCP) – Appendix I of the Project CEMP).

Condition 98 of R/REG/2014/5436 requires that a copy of the ITA EMP (certified version) is kept on site and is accessible at all times.

This ITA EMP 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 D. A number of related management plans are referenced throughout this ITA EMP to avoid duplication of information and thereby enable efficient document control. The other relevant plans are the Project CEMP, Project ESCP (Appendix I of the Project CEMP, including Appendix D - Chemical Treatment Management Plan (CTMP)) and the Project Emergency Spill Response Plan (ESRP) (Appendix T of the Project CEMP).

2.3

WATER TREATMENT SYSTEM

Groundwater and rainwater which collects in the trench during construction works will be treated as detailed in the ESCP and CTMP. During the first phase of trench excavation, dirty water will be pumped to settlement devices. As trench excavation proceeds, a specifically designed water treatment plant (WTP) will be located within the trench. The WTP will treat water from the construction site active construction areas. The details of the water treatment system are included in the ESCP and may be subject to change as water treatment requirements dictate.

It is noted that for CSA 6, dirty runoff will drain to the construction trench for containment and treatment.

The construction support deck will have maintained clean to prevent or minimize un contained dirty runoff leaving the construction site.

Within 30 days of the installation of the water treatment system, and prior to operation, a discharge monitoring programme, to assess the ongoing adequacy of all management practices, shall be developed in accordance with Resource Consent conditions 101-104 (refer Section 2.3 of this ITA EMP and Section 3.5 of the CTMP).

As required by Resource Consent condition 103, action is required if discharge sample results exceed trigger levels. The ESM will be immediately notified and communicate with Council to fulfil the following consent requirements: Within five working days of receipt of sample results showing contaminants exceeding the agreed trigger levels (Condition 101(e)): •

an investigation shall be undertaken to determine why exceedances were detected and to identify any additional source controls or treatment required; and

•

the results of the investigation shall be reported to the Council (Team Leader Central Monitoring).

4 ON-SITE DRAINAGE The existing drainage system consists of the Auckland Council stormwater network currently in place within the Project site. This drainage system collects runoff from the road pavements and directs it to the stormwater pipelines which then discharge directly into the Waitemata Harbour through the existing discharge structure located at the Promenade. The release of contaminants to the stormwater network will be managed using the controls described in the Project ESCP and this ITA EMP. Discharge to sewer network may also be undertaken where water quality requirements for storm water cannot be met.

Appendix A provides site plans showing the existing stormwater drainage system within and adjacent to the Project site, including the ITA areas of CSAs 4, 5 and 6. The drawings also outline methods to manage sediment release during construction. Further details on sediment control methods can be found in the ESCP. •

5 POTENTIAL CONTAMINANTS AND MANAGEMENT CONTROLS Table 3 sets out the activities on site with the potential to generate contaminants which may enter the stormwater network. It also provides an assessment of the level of that risk and outlines structural and procedural controls to manage that risk. The Project Emergency Spill Response Plan (ESRP) (Appendix T of the Project CEMP) provides emergency response arrangements covering Environmentally Hazardous Substances (EHS).

Risk has been assessed in accordance with the Contractor’s Risk Assessment Guideline to establish an initial risk prior to controls (R1) and a residual risk after controls have been put in place (R2). Both assessments consider both likelihood of occurrence and level of consequence.

6 RISK MANAGEMENT 6.1

STRUCTURAL CONTROLS

The following structural controls will be put in place to ensure that spills and contaminated water do not enter the stormwater system and receiving environment: •

Bunding of Environmentally Hazardous Substances (EHS) – bunding will be provided where required and designed to contain a volume of 110% of the largest container. This ensures that if the largest container ruptures the spillage can be contained until it can be disposed of safely.

•

Settlement Tanks- Settlement tanks will be used to treat water from both the CSAs and the active construction zones. The tanks and any associated treatment device(s) will be designed to ensure that discharge levels comply with the identified trigger levels which are associated with the monitoring parameters established under Resource consent condition 101.

Resource consent condition 99 specifies using two 12,000L settlement tanks to achieve the discharge levels outcomes specified as per resource consent condition 101. However, Resource consent condition 100 enables modifications to the specifications of condition 99, subject to providing the following information to Council for their certification: •

Plans and drawings outlining the details of the modifications; and

•

Supporting information that details how the proposal does not affect the capacity or performance of stormwater management system.

Section 2.1.8 of the Project ESCP outlines the proposed water treatment methodology which is to be applied to the ACZ and CSAs. Connectus have investigated modifying the structural control specifications outlined in condition 99 to achieve better and more efficient water quality outcomes.

Connectus and AT have been in dialogue with Council Officers, who have provided agreement in principle to such modifications to the structural controls specifications.

If Connectus decide to proceed with the current modifications to the structural controls (or any other such specification which achieves the outcomes specified by condition 101), such changes will be certified by AC in accordance with condition 100.

A Project Emergency Spill Response Plan (ESRP) (Appendix T of the Project CEMP) has been prepared for the Project. It includes the provision that all spills over 20 litres, or any spill of Environmentally Hazardous Substances that has entered the stormwater system, a water- body or has contacted unsealed ground, shall be reported immediately to the AC 24 Hour Pollution Hotline (09-377-3107).

6.3

DISCHARGE MONITORING

Within 30 days of the installation of the water treatment system, and prior to operation, a discharge monitoring programme, to assess the ongoing adequacy of all management practices, shall be developed and submitted to AC (Team Leader Central Monitoring) for certification.

The type and design of the water treatment system has yet to be confirmed. Once confirmed the Discharge Monitoring Programme will be developed. The programme will be developed to comply with the requirements of resource consent conditions 101 -104.

The monitoring programme will be set out in Section 3.5 of the CTMP (Appendix D of the Project ESCP).

7 SITE INSPECTION AND AUDIT 7.1

INSPECTION PROGRAMME

The purpose of the ITA related site inspections is to ensure the integrity of activities on site and to ensure that those activities do not result in the off-site discharge of contaminants that might have adverse effects on the receiving environment.

The general type and frequency of inspection is provided in Section 5.2 of the Project CEMP. An example weekly inspection check list is provided in Appendix B:

7.2

AUDITING

External environmental audits will be carried out on the Project on at least an annual basis by Connectus Parent Company Staff. The purpose of carrying out an environmental audit is to have the implementation of and compliance with environmental management procedures and control measures checked independently. This can then be reported accordingly to enable any discrepancies to be identified and actioned.

The environmental audit will include the requirements of this ITA EMP and further detail is provided in Section 5.3 of the Project CEMP.

8 TRAINING Staff and visitors will require induction training to increase awareness of the environmental risks associated with the activities on site and to ensure that the appropriate control measures are properly implemented.

Identification of key environmental risks and consequences

•

Identification of ITA “at risk” activities and control measures

•

Roles and responsibilities

•

Identification and familiarity with relevant procedures and JSEA’s & CEP’s

•

Site housekeeping

•

EHS management

•

Waste management

•

Spill management and emergency response

•

Incident reporting

The HSNO Act 1996 requires that certain hazardous substances are under the control of an Approved Handler. Any staff required to handle such substances will be required to hold or obtain an Approved Handler Certificate.

9 DOCUMENT REVIEW This ITA EMP will be reviewed at least annually throughout the course of the Project or as a result of any material changes associated with a new or changed activity, equipment or location of activities.

The review process is detailed in Section 5.7 of the Project CEMP and will consider the environmental controls and procedures to make sure they are still applicable to the activities being carried out. Any change to the ITA EMP will be submitted to AC for certification and no activity reliant upon a change to the ITA EMP can be undertaken until the change has been certified.

The reasons for making any changes to the ITA EMP will be documented and a copy of the original ITA EMP document and subsequent versions will be kept for the project records.
