1 INTRODUCTION The purpose of this Addendum to the City Rail Link (CRL) Enabling Works Contract 2 (C2) Industrial and Trade Activities Environmental Management Plan1 (ITA EMP) is to ensure that activities associated with the CRL C2 Public Realm Reinstatement (PRR) works meet the requirements of the conditions (resource consent 2) set out in Section 1.2 of the existing CRL C2 ITA EMP. The specific purpose of this Addendum is to deal with potential discharges associated with the PPR phase of the construction works that were not covered in the CRL C2 ITA EMP. Where the adverse effects from a specific activity are already covered in the CRL C2 ITA EMP, reference is made to the appropriate section.
2 PROJECT DESCRIPTION This section presents a summary of the PRR works to provide context to the ITA EMP Addendum. A detailed description of the PRR works is provided in the CRL C2 Construction Environment Management Plan (CEMP) – PRR Addendum (CRL-PAT-RME-AT-RPT-033021).
2.1
CONSTRUCTION METHODOLOGY OVERVIEW
Following the completion of the cut and cover trenched section of the CRL tunnel along Albert Street between Customs Street and Wyndham Street, Connectus will progress with the reinstatement of the public realm along and around the physical works area. Connectus anticipate that the completion of the cut and cover trenched section will be achieved progressively from south to north along Albert Street. Accordingly, as the tunnel is progressively completed Connectus will undertake the PRR works in a staged manner along the works area, readying Albert Street and surrounding works area for public access once again. The PRR works include the re-instatement of the road carriageway and footpaths, urban design enhancements, and landscaping. The area for reinstatement expands beyond the works area for the cut and cover trenched section, reflecting a logical transition between the reinstated works area and surrounding public realm. Figure 1 provides an overview of the PRR works area. These works will be undertaken using standard methods, including using jackhammers and backhoes to remove old pavements, and rollers and compactors to prepare the base course/bedding for new paving. Pavers and curb stones will be cut as required using appropriate equipment. Note: Parts of the PRR works area are located outside the CRL designation. Any works outside the CRL designation are not specifically considered within this CRL C2 EMP. If required, separate resource consents will be applied for these areas.

2.2
CONSTRUCTION PROGRAMME OVERVIEW
The PRR works will progressively follow the completion of the cut and cover trenched section of the CRL tunnel along Albert Street between Wyndham Street and Customs Street West. As completion of the cut and cover trenched section of the CRL tunnel will occur south to north progressively along Albert Street, so too will the PRR. The exception to this is the Lower Albert Street works between Quay Street and Customs Street West which will occur first to achieve parallel construction timeframes with the Commercial Bay development. Table 1 provides an overview of the construction staging as it relates to the PRR works. Within each area of works there will be multiple works phases (refer to the CRL C2 CEMP PRR Addendum for further detail regarding works phasing).

4 ON SITE DRAINAGE There is no change to the existing drainage system and controls set out in Section 4 of the CRL C2 ITA EMP. Appendices 1-3 in the Erosion Sediment Control Plan Addendum (CRL-PAT-RME-AT-RPT033016) also addresses this in relation to PRR works in more detail.
5 POTENTIAL CONTAMINANTS AND MANAGEMENT CONTROLS There are no changes to the potential contaminants and management controls outlined in Table 3 of the CRL C2 ITA EMP. However, it is noted that the following activities will not occur during the PRR works and therefore do not require mitigation during this time:
Storage of Jet grout pump and mixing plant (only on CSA 2 and 4). Stormwater and groundwater treatment tanks in CSA4.
6 RISK MANAGEMENT There is no change to the risk management measures stated in Section 6 of the CRL C2 ITA EMP.
7 SITE INSPECTION AND AUDIT There are no changes to the inspection programme requirements or auditing process detailed in Section 7.1 of the CRL C2 ITA EMP, with the exception of the item below as it not required as per the CRL C2 ESCP PRR Addendum (CRL-PAT-RME-AT-RPT-033016):
Check that water treatment system is operating correctly to manage contaminated water.
8 TRAINING There is no change to the training related activities included in Section 8 of the CRL C2 ITA EMP.
9 CONCLUSION The existing CRL C2 ITA EMP provides sufficient construction managements protocols to manage any ITA discharges during the PRR phase of construction. The existing management protocols detailed in

the CRL C2 ITA EMP will appropriately manage any environmental effects from industrial and trade activities associated with the PRR phase of construction.
