Purpose of the Industrial and Trade Activities Environmental Management Plan
This ITA EMP has been prepared to manage adverse effects relating to industrial and trade activities required during construction of the Project, including a bentonite treatment plant, jet grout plant and the storage and handling of hazardous substances. Specifically, the purpose of the plan is to identify those activities to be undertaken at the Project site that may result in contamination of land and/or stormwater, and to document the procedures to be implemented to appropriately manage these risks. The ITA EMP is required under Condition 96 of Discharge Permit R/REG/2014/5436 for the CRL Britomart to Wyndham Street enabling works. The plan is an updated version of the Draft ITA EMP – Britomart to Wyndham, dated December 2014, prepared by Golder Associates (NZ) and submitted to Auckland Council (AC) as part of the regional resource consent applications for the Project. The ITA EMP outlines the following: Identification of industrial and trade activities to be undertaken during the Project that may result in contamination of land and/or water; Identification of potential contaminants associated with these activities; The methods to be used to prevent identified contaminants from contacting with stormwater runoff and methods to manage environmental risks from on-site activities; An appropriate monitoring and auditing programme to ensure site performance is undertaken in accordance with this ITA EMP; and Industrial and Trade activities Environmental Management Plan

Project Description
2.1
Overview
The Project involves the construction of an extension to the existing passenger rail network from the current termination point within the BTC, westwards underneath the CPO and Lower Queen Street. Separate works are being undertaken to continue the CRL tunnels from this point under the Downtown Shopping Centre site (which is to be redeveloped by Precinct Properties), and then up Albert Street. Significant works beneath the CPO will be undertaken, with the construction of two new rail tunnels extending westwards beneath the basement floor level. In Lower Queen Street, sheet piling will be extended across the road corridor, excavation undertaken to form the rail tunnels followed by reinstatement of the road corridor following the completion of works. During construction, existing ticketing and retail functions and pedestrian access to the station will be accommodated in Station Plaza, at the rear of the CPO building. Surface works will also be required in QEII Square associated with the Downtown Shopping Centre redevelopment, including construction of the CRL rail tunnels beneath this site (Precinct Properties scope of work). A detailed description of the construction works is provided in the CEMP.
2.2
Construction zones
The Project will be divided into four discrete active construction zones (ACZ) as shown in Figure 2.1.

2.4.1
Bentonite treatment plant
A bentonite plant will be located adjacent to the south west corner of the CPO building on Lower Queen Street. The purpose of the plant is to mix and recycle bentonite slurry associated with the diaphragm wall construction. The plant will cover an area of approximately 350 m2 and comprise the following elements: Four to six 80 m3 silos, approximately 15 m in height, required for the storage of bentonite slurry and waste; Slurry Treatment Plant (STP) / De-sanding Unit - with a capacity of approximately 450 m 3; Bentonite mixer; Bentonite storage bags; Generator; and Excavator. The bentonite plant operation will be as outlined in Table 2.3 and as shown on Figure 2.5. Table 2.3:
Bentonite Plant Operation
Bentonite Storage
Storage of bentonite powder and slurry within silos
Bentonite Mixing and Recycling
Mixing of bentonite with water and additives (sodium bicarbonate and bentocryl) to make a bentonite slurry, which will be temporarily stored within the silos before being used in the piling operations. The bentonite mixer will be covered to control bentonite powder dust emissions. Transfer of the bentonite slurry to the storage silo, which is connected to the circuit of the STP / de-sanding unit and down to the diaphragm wall operations via pipes and hoses. Slurry will be pumped out from the trench and travel back to the de-sanding unit / STP, where it will be treated to remove solids and recover the slurry for re-use.
Spoil Disposal
Dry material recovered from the de-sanding unit will be removed off-site. Liquid spent slurry following de-sanding will be discharged into a temporary spoil pit (approximately 24 m3) to be located on site. The spoil will be excavated and transported via trucks (approximately 3-5 per day) to an approved disposal facility.
Management of Discharges
The entire bentonite plant will be bunded to contain any spilt material or bentonite slurry in the event of a pipe or pump failure during transfer of the slurry. Any surface water collected in the bunded area will be pumped to the sediment control system on-site for removal of sediment prior to discharge. There will be no gravity discharge of any water from the bunded area to the stormwater system. Any spilt material pumped to the sediment control system will be treated as per other sediment laden water on-site with discharge only occurring once the minimum water quality standards are met.

2.4.2
Jet grouting plant operation
The main function of the jet grout plant is to mix the cement grout required for the jet grout columns and transfer it to the jet grouting rig at high pressure. The plant will be located adjacent to the north western corner of the CPO building on Lower Queen Street (refer Figure 2.3). The plant will comprise the following elements: Excavator; Grout Mixer; High Pressure Pump; Generator; Silo for cement powder storage; and Grout Storage Tank (approximately 10 m3). The jet grout mixing plant will involve mixing water and cement and additional additives to create a slurry mix as outlined in Table 2.4. Table 2.4:
Jet Grouting Plant Operation
Material Storage
Cement powder will be delivered to the plant by trucks. It will be pumped to the storage silo through hoses. Dust filters on the silos will be used to control dust emissions.
Cement Grout Mixing
Cement powder will travel to the mixer via a closed screw conveyor. The scale will have a protective cover to control dust. Cement powder will be mixed intermittently with water in the required proportions and the grout will then be stored in a tank.
Cement grout injection:
Grout will travel via hoses, filters and pumps to the high pressure pump, then to the jet grouting rig and through the drill string, which will inject this grout at high pressure, inside the soils, to form jet grouting columns.
Industrial and Trade activities Environmental Management Plan
June 2016
11 Spoil Disposal
The resulting sludge (made of grout, water and soil) will be pumped from the jet grout column location to the spoil pit at the plant. It will be disposed of in a similar manner to the slurry spoil.
Management of Discharges
The jet grout plant will be bunded. Any surface water collected in the bunded area will be pumped to the sediment control system on-site for removal of sediment prior to discharge. There will be no gravity discharge of any water from the bunded area to the stormwater system. Any spilt material pumped to the sediment control system will be treated as per other sediment laden water on-site with discharge only occurring once the minimum water quality standards are met.
2.5
Stormwater and groundwater treatment
Stormwater and groundwater that settles in the excavations in Lower Queen Street and the CPO will be pumped into a settlement tank where sediment will settle out. Assisted sediment settlement using chemical or non-chemical flocculants (the latter being preferred if effective) will be undertaken as required to ensure water discharged from the system will not result in adverse effects on the receiving environment. The treatment tanks will be located adjacent to the south east corner of the CPO adjacent to the glasshouse. The treatment plant is outlined in detail in Section 2 of the Chemical Treatment Management Plan (CTMP) for the Project (Appendix B of the Project ESCP). The treatment plant comprises a total storage capacity of 35,000L, which exceeds the volume requirement of two 12,000L tanks specified in Condition 99 of Discharge Permit R/REG/2014/5436.

Site drainage
The existing drainage system consists of the AC stormwater network currently in place within the Project area. 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 (immediately adjoining the northern side of Quay Street). Refer to Section 4.6.3 of the ‘Auckland City Rail Link Britomart to Wyndham Water Quality Assessment’ dated December and prepared by Golder Associates for information on the receiving environment water quality. Parts of the existing drainage system will need to be removed or closed off during the Project works. A drainage plan showing the existing stormwater drainage system and those sections to be removed is shown attached in Appendix D. The release of contaminants to the stormwater network will be managed using the controls described in the Project ESCP and this ITA EMP. Site layout plans have been prepared (refer to Appendix D of this ITA EMP) to show the location of the bentonite plant, the jet grout plant, truck routes and any chemical storage areas. Final as-built drainage plans for the Project area will be prepared following the completion of the works. These plans will show the locations of all stormwater catch pits and discharge locations within the Project area.

Management Procedures and Mitigation Measures
4.1
Bentonite plant
The main environmental risks associated with the bentonite plant are the discharge of chemicals from the operation of the plant and/or the discharge of sediment laden water to stormwater drains within the Project area, which in turn discharge into the Waitemata Harbour. To avoid or minimise any discharges from the bentonite plant to the surrounding environment, the plant will be designed and operated as follows: The entire bentonite plant shall be bunded to contain any spilt material or bentonite slurry in the event of a pipe or pump failure during transfer of the slurry. The outlet of the existing stormwater catchpit in Lower Queen Street that will be located within the bentonite plant operation area (refer to the Stormwater Drainage Plan in Appendix D of this ITA EMP) will be sealed off during the works, and a submersible pump installed to pump any surface water that collects in the bund to the bentonite plant tanks for re-use; or to the sediment treatment plant. Sodium bicarbonate and bentocyrl will be added to the bentonite slurry. Neither chemicals are classified under HSNO as hazardous, and will be stored within the bunded bentonite plant area. No other environmentally hazardous substances will be required as part of the bentonite plant operation. In the event of a spill outside of the bunded area, the standard spill control procedures will be implemented to contain and manage the spill (refer to Section 5 of this ITA EMP). Prior to commissioning of the bentonite plant, an Operations and Spill Response Plan will be prepared for the plant. This Plan will outline the environmental controls and spill response procedures specific to the operation of the plant detailed in Section 2.4.1 of this ITA EMP. The extent of the bunded area and the location of the existing catchpit within the operational area of the bentonite plan that will be sealed off during the works is shown on the Stormwater Drainage Plan in Appendix D.
4.2
Jet grout plant and operation
The main environmental risk associated with operation of the jet grout plant is the discharge of sediment laden water and elevated pH from cement used in the slurry mix. To avoid or minimise any discharges from the jet grout plant into the surrounding environment, the plant will be designed and operated as follows: The jet grout plant shall be bunded with any surface water collected in the bund draining to the onsite sediment treatment plant. The outlet of the existing catchpit in the plant operation area (refer to the Stormwater Drainage Plan in Appendix D) will be sealed off, and a submersible pump installed to pump surface water to the sediment treatment plant. In the event of a spill outside of the bunded area, the standard spill control procedures will be implemented to contain and manage the spill (refer to Section 5 of this ITA EMP). Prior to commissioning of the jet grout plant, an Operations and Spill Response Plan will be prepared for the Plant. . The Plan will include the relevant environmental controls and spill response procedures specific to the operation of the plant detailed in Section 2.4.2 of this ITA EMP.

Environmentally hazardous substance management
The principal environmentally hazardous substances that will be stored and used during the construction works will include: Petrol; Industrial and Trade activities Environmental Management Plan
June 2016
16 Diesel; Jet grouting additives; and Bentonite. Dangerous and hazardous substances shall be stored on site in accordance with the Hazardous Substances and New Organisms (HSNO) Act 1996 and relevant HSNO regulations, and subject to provisions relating to Location Test Certificates and Approved Handlers, as appropriate. All chemicals will be stored in a secure area with secondary containment to contain any spills. Safety Data Sheets (SDS) for all of the chemicals used or stored in the Project area will be kept in the Project site office with a sub-set on file at each storage location relevant to the specific materials being stored. A Hazardous Substances and SDS register shall be kept on-site and regularly maintained to ensure it is up to date with the chemicals and volumes of chemicals used and stored on-site. Spill kits and associated spill response equipment, will be available at each vehicle entrance (refer to Appendix C of this ITA EMP). The storage, handling and disposal of dangerous goods will be undertaken in accordance with the following DSBJV Environmental Work Instructions: WI 101 Use and Disposal of Oils and Lubricants; WI 102 Refuelling of Equipment, Machinery and Static Tanks; WI 103 Spill Procedure: Fossil and Synthetic Fuels and Oils WI 602 Road Transport and Materials Handling; and WI 603 Storage and Handling of Dangerous Goods.
4.4
Waste management
For the purpose of the Project, waste material refers to items removed from worksites and road carriageways, such as surplus or reject spoil, excavated seal, pipes, rubbish detritus and any other unwanted materials. Appropriate disposal shall be arranged for any material that requires off-site disposal. If hazardous material requires off-site disposal, it will be disposed of safely, through an appropriate contractor authorised to handle, transport, process or safely dispose of the waste concerned to an approved disposal facility. Any waste bins on-site will either be stored undercover, or will be installed with covers to prevent rainwater ingress. Overall waste management or disposal requirements will vary depending on the material concerned and shall be undertaken in accordance with the WARRP.
4.5
Vehicle refuelling
No permanent storage of bulk fuels will occur on-site. Refuelling of plant and equipment will be undertaken using either a mini-tanker for larger equipment, or portable containers (such as jerry cans) for smaller plant and equipment. Refuelling will be undertaken in accordance with work instruction WI 102 - Refuelling of Equipment, Machinery and Static Tanks.
4.6
Wash-down
No vehicle wash-down will be undertaken on-site, apart from localised washing of vehicles and tyres as required in order to prevent the tracking of sediment onto the surrounding road network. The location and nature of the construction works, along with the construction methodology will serve to minimise the Industrial and Trade activities Environmental Management Plan
June 2016
17 potential for site vehicles to drive over areas of open excavation or unpaved areas and track dirt onto the surrounding road network. The removal of spoil from the excavations will be undertaken as follows: Material will be excavated using diggers within the excavation area or a long reach digger on the edge of the excavation; Trucks will back up to the edge of the excavation area on the existing sealed surfaces; and Material will be loaded directly into the trucks to avoid the storage of excavated material on-site. In the event of material being spilled onto the ground around the excavation or from trucks transporting the spoil from the excavation, the material will be cleaned up prior to the vehicle leaving the site. This may involve some localised washing of vehicles and tyres. Any runoff from the wash down area will directed to the on-site sediment control system. Some washing of machinery within the excavation area may be required. In this instance, washing of machinery will be undertaken using a hose or water blaster on-site within the excavation area only.

Spill Response
The management of spills at the site will differ depending on the quantity, type of material and location of the spill. As no significant volumes of environmentally hazardous substances apart from those at the bentonite and jet grouting plants are anticipated, the spill response procedures for the Project have been divided into three separate procedures as follows: General Emergency Spill Response Plan, which covers all areas of the site; Bentonite Plant spill response procedures; and Jet Grout Plant spill response procedures. A general Emergency Spill Response Plan (ESRP) has been prepared for the Project (refer to Appendix C of this ITA EMP). The ESRP includes provision that in the event of all spills over 20 litres, or any spill of Environmentally Hazardous Substances, which has entered the stormwater system, a water-body or has contacted unsealed ground, the spill shall be reported immediately to the AC 24 Hour Pollution Hotline (09-377-3107). Additionally, Cooper and Company will be notified if spills (as described above) occur within / or are likely to affect the Britomart Precinct. The spill response procedures for the bentonite and jet grout plants will be detailed in the Operation and Spill Response Plans to be developed prior to commissioning of the respective plants. As both areas will be bunded, the specific spill response requirements will be considered as part of the final development of the site specific controls for each area. A site plan has also be developed, which shows the location of all spill kits in the Project area (refer to Appendix C of this ITA EMP). Spill kits and signage relating to spill response procedures will be located at each vehicle entrance to the site during each stage of work. Each spill kit will have a register of contents and an inspection sheet. Each spill kit will be inspected monthly to ensure all contents are present and there is no rubbish in the kits. The inspection sheet shall be signed during each inspection.

Storage and Handling of Dangerous Goods
Building Requirements: Storage buildings should be sited so that the risk of contamination of people, crops, animals and the environment is minimised. The building must: be at least 15-20 metres from any source of ignition (fire, workshops, furnace, smoking area, etc); be at least 5 metres from any other building, boundary or deemed road; be sited so that dangerous fumes are not carried into sensitive environments; have easy access for vehicles and emergency services; and be away from vehicle thoroughfares and protected with bollards. Environmental Protection To protect the surrounding environment the building must: have internal bunding sufficient to hold 110% of the contents of the largest container; have an impermeable concrete floor (implies a suitable surface coating); have a bund around the external access (a small nib wall); be as far away as practicable from any storm water grates; and have an emergency spill kit. Construction Materials The Hazardous Substances (Classes 1 to 5 Controls) Regulations require a number of controls for hazardous substance locations in order to reduce the likelihood of unintended ignition of Class 2, 3 or 4 substances, including: fire resistant walls; separation distances from ignition sources; and safety requirements for electrical equipment (construction, design, earthing). In addition, the New Zealand Building Code provides ‘acceptable solutions’ as a means of complying with the Building Act 1991. The recommended generic design must meet the following criteria: Be constructed of non-combustible materials (concrete) Be constructed with no windows, and door opening outwards An impermeable membrane/coating on the floor to contain spills All surfaces painted or sealed to avoid contamination No electrical fittings (if electrical fittings are required for any reason, these must be intrinsically safe) Ventilation For health and safety reasons the building must have adequate ventilation. Static venting using high and low level vents, covered with 0.5mm nominal aperture brass-wire gauze where within 1.5 m of the ground. Forced air extraction is not required.

Waste Oil Storage
Introduction Waste oil storage facilities should be designed and managed in accordance with the Guidelines for the Management and Handling of Used Oil in New Zealand (MfE/OSH, 2000). Used oil collection facilities are classified as either controlled collection or general collection sites. This classification is based site manager’s ability to prove that other products do not contaminate the used oil on site. Controlled collection sites can meet less stringent design requirements on the basis that provision does not have to be made for highly flammable liquids, such as fuels. Siting The following matters should be considered when siting a waste oil storage tank: Suitable positioning to facilitate supervision by the operator who has responsibility for what is emptied into the container Location on an impermeable surface such as concrete or asphalt Safe access for tankers during unloading The use of bollards if the tank is located near vehicular traffic Location at least two metres away from potential hazards such as recycling or rubbish bins Tanks should be located outdoors, inside a bund able to hold 110% of the contents of the tank The bund should either be roofed, or adequate provision made for the inspection and safe disposal of clean storm water. If the bund is fitted with a drain valve, it should be lockable or the handle should be removed. Construction Generally, the maximum container size for fibreglass or plastic igloos at public used oil collection points should not exceed 1000 litres, and only one tank will be permitted per site. Tanks greater than this size will require consent in writing from the Chief Inspector, Explosives and Dangerous Goods. Used oil containers may be constructed of plastic, metal or glass reinforced plastic, provided they meet certain performance criteria set out in the Guidelines The requirements of the tank include:

WORK INSTRUCTION
WI-603
Storage and Handling of Dangerous Goods a lockable opening at the top of the tank, a permanent mesh at the fill point, a discharge outlet fitted with a lockable valve, and a vent.
The tank should be labelled with: the safe fill level; manufacturer and date of manufacture; content and prohibited substances labels as per the MfE Guidelines; Class 3 dangerous goods diamond. The waste oil collection facility will require a Test Certificate (formerly known as a Dangerous Goods licence). Personal Hygiene For health and safely purposes, personal hygiene must always be strictly maintained. To help maintain personal hygiene when handling chemicals, staff should follow these procedures: NEVER touch your face when you have been handling waste. ALWAYS wash your hands with soap and warm water at least once before eating, smoking, touching your face, or going to the toilet. NEVER smoke in or near the dangerous good storage area. WASH spills off your skin immediately. STOP WORK and get fresh air if you feel unwell. Advise your supervisor. Staff must not take work clothes home for laundering that may have become contaminated with hazardous substances. Any clothing that has become contaminated should be placed in a plastic bag for disposal or, if contamination is light, specific arrangements made with a commercial laundry company.
Monitoring and Recording
Daily visual inspections of site operations by the site supervisor.
Non Conformance Corrective Action
Any change to the storage area, or quantities stored, is to be first agreed by the Zero Harm Advisor.
Audit Provisions
Regular audit is the responsibility of the Zero Harm Advisor, who will check that the site operates in accordance with government legislation, local government specifications and Downer policies and work instructions.
Monthly inspections of the storage facilities by the Zero Harm Advisor.
Non conformances are to be followed up and remedied immediately by the Zero Harm Advisor.

Appendix C:
Spill Response Plan
Auckland City Rail Link – Britomart Enabling Works (Contract 1) Emergency Spill Response Plan 1.0
Purpose and Objective of Plan
Environmentally Hazardous Substances (EHS) will be present in Project construction areas. This ESRP relates to the management of spills of EHS’s and the prevention of adverse environmental effects. The objective of this Emergency Spill Response Plan (ESRP) is to ensure that emergency spills are handled in an appropriate manner to ensure safety of all personnel and to prevent damage to the environment. This ESRP covers the spill response procedures for the general areas included in the Active Construction Zones (ACZs) and Construction Support Areas (CSAs). Spill response procedures for the Bentonite and Jet Grouting plants will be detailed in the specific operations and spill response plans to be developed prior to commissioning of these plants.
2.0
Spill Response in ACZs and CSAs
Spillages within the ACZs will be managed and cleaned up on site in accordance with this ESRP. Any contamination of rain water or groundwater within the trench will be treated as per the Project ESCP prior to release or disposal. Spillages within the CSAs will be managed and controlled within the CSA. Spill risk will be managed through structural and procedural controls. In the event that these controls fail, management will be by way of adherence to the procedures outlined in this ESRP.
3.0
Hazardous Substances and Spill Response Procedures
Safety Data Sheets for all hazardous substances associated with the Project construction works are held at the site office. These will be consulted to determine the appropriate course of action to take in an emergency situation, e.g. spillage. Spill kits and associated equipment, are located at each vehicle entrance to the site as shown on the attached stage plans.
