Pur pose off the En vironm ental M Managem ment Frramewo ork

AT is seeking A Notices of Requirement (NoR) to dessignate land (including sttrata) for thee constructio on, operation n and maintenaance of the C City Rail Link (CRL). The CCRL is a 3.4km m undergrou und passengeer railway (in ncluding two o trracks and thrree undergro ound stations) running b etween Brito omart Station and the Noorth Aucklan nd Line (NAL)) in n the vicinityy of the existiing Mount Eden Station. The CRL alsso requires an additional 2.6km of modifications within the NA w AL including aa rail interchange adjaceent to the Do ominion Road d over‐bridgee.

A full descript A tion of the CRL is contain ned in the Citty Rail Link: A Assessment o of Effects on n the Environment (AEE).

In n order to ap ppropriately assess the CRL within thee statutory fframework re equired by thhe Resource e Management M t Act 1981 (R RMA) for NoR Rs, a “conserrvative” effeccts envelope e approach hhas been ado opted (as described mo ore fully with hin the AEE). mental Mana agement Fram mework (EM MF) has been developed tto support thhe NoR and p provides an This Environm overarching framework w within which mechanismss are develop ped to mitiga ate actual annd potential adverse effects from tthe construction, operatiion and mainntenance of the CRL. The e purpose of this is to enssure that anyy effects are avvoided remed died and/or mitigated thhroughout th he project life ecycle.

The EMF apprroach has beeen develope ed to supporrt a consisten nt and integrrated approaach to addressing environmentaal management througho out the projeect lifecycle.

The EMF provvides a broad d environmental manageement appro oach consiste ent with AT’ss environmen ntal and su ustainability practice, and outlines ho ow this apprroach aligns w with the ove erarching prooject deliveryy frameworkk.

3.1 3 Enviro onmental Managem ment Plan The Environm mental Management Plan n (EMP) is thee core docum ment within the EMF. Thhe EMP will a address all major activitie m es to be und dertaken as p part of the deesign, constrruction and o operation of the CRL. This will includ de project aspeccts or activitiees covered b by the designnations and ffuture resource consentss. Responsib bility for Principal.1 Th he following g key docume ents and administration and implementation of the EMP is with AT as P principles willl guide the d developmentt of the EMP:: •

•

The EMP will include the mitigation an nd conditionns of the NoR R and future resource connsents.

In return, it is eexpected tha at the Contraactor will be proactive in delivering ppositive proje ect performance against thesse parameterrs.

The EMP will be reviewed d on a regular basis to ennsure it remaains relevant and compliees with the cconditions off any statutoryy authorisatio ons and apprrovals.

The EMP will be structureed to minimisse the numbber of Contraactor plans re equired. Thi s approach a avoids too many individu m ual plans for the manage ement of a raange of effeccts, whilst alsso recognisinng the need ffor certaintyy re egarding envvironmental outcomes.

3.2 3

Com mmunicatio ons Plan

The EMF inclu udes a comm munications p plan which A AT will have rresponsibilityy for as Princcipal. Key co omponents o of th his plan will iinclude: •

Developin ng a communications framework thaat reflects acccountabilitie es, AT’s comm munications strategy and d any otherr relevant maatters;

•

Project co ommunicatio ons, such as:

•

o

D Disseminatingg any relevan nt informatioon throughout the project team;

o

R Reviewing reggular projectt reports proovided by Contractors to identify any issues or risks;

Communications with h stakeholders, such as: o

D Disseminatingg any relevan nt informatioon to inform the public a and stakeholdders of proje ect matters and developm ments where e appropriatee;

o

Processes forr receiving an nd handling ccomplimentss and compla aints.

3.3 3

Funcction Speccific Requirements

The EMP will be supporteed by a mana agement plann for each off the primaryy project phaases and funcctions.

Design Mana D gement Plan n (DMP) The DMP is a tool that willl enable the project to ““self‐check” tthe design an nd constructtion contractt re equirementss against the EMP and sta atutory authhorisations be efore advanccing any phyysical works. The key focu us of the DMP iss the Environ nmental Consstraints and Opportunitie es (ECO) Che eck – which i s a reconcilia ation of the design againsst statutory aand project requirementss (as capture ed within the e EMP).

This refers to engineerin ng design.

Pag ge 6

www.aucklan w ndtransportt.govt.nz

City Rail Link C k: Auckland Transport R Requiring A Authority Staatus The purpose o of this recon nciliation is tw wofold and i s not only to o check the d design, but allso to identiffy other matters arisin m ng from the d design that n need to be inncluded within the subsequent phasees (i.e. construction and operations).

Construction Environmen ntal Manage ement Plan ( CEMP) The CEMP willl be the mosst complex o of the docum ments prepared within the EMF given the range of environmentaal matters th hat need to b be addressedd during the construction n of the CRL. An importa ant re equirement of the CEMP P is that it does not mere ly repeat the e requiremen nts of the EM MP, but rathe er establish sp pecific detaills on how the Contractorr will give efffect to it. Th his includes d details of wh ere environm mental risks are located an nd exactly ho ow these are e to be mitig ated.

The CEMP willl: •

Establish an effects en nvelope and focus on thee strategic and perimeter controls annd interfacess;

•

Address ccumulative eeffects and in ntegrate consstruction staaging, works and program mming to minimise effects;

•

Provide a framework to support a a number of Delivery Wo ork Plans (DW WPs).

The CEMP and DWPs are discussed further in secttion five.

Delivery Wor D rk Plans (DW WPs) DWPs will add D dress specific environme ental areas o n an effects basis (e.g. th he Road Netw work & Transportation Noise & Vibration Work Plan), or by work site where all effeccts are integgrated. Indica Work Plan or W ative DWPs are included iin this EMF ffor the purpo ose of illustraating the typ pes of matterrs that will bee considered d and addressed wh hen the full w work plans are formulateed by either A AT or its Con ntractors/Connsultants. Th he EMF approach (outlined here aand discussed further in section four) provides fle exibility to ennable the most effectivee so olutions to b be adopted fo or the projecct, provided these complly with the applicable ge neric and specific co ontractor req quirements.

Operational C O Compliance Plan (OCP) The OCP will cclearly identify any opera ational requ irements and d maintenan nce regimes ffor the physiical assets an nd se ervice‐based d delivery asp pects of the project. Thiss plan will co over matters such as opeerational KPIss, roles and re esponsibilitiees and proceesses for ensuring that teenants, operaators and contractors givve effect to tthe OCP and EMP.

Owner’s Man O nual (OM) The OM will d document alll on going co ompliance reequirements and statutorry obligationns together w with all re elevant speccifications and calculation ns needed too enable AT tto effectivelyy manage, opperate and m maintain its faacilities. Thee OM will also serve as a central storee for other key CRL documentation inncluding as‐b built in nformation, tthird party agreements a and mainten ance frequencies/requirements.

Envvironme ental Ma anagem ment

Proaactive and Flexible A Approach

Sound environmental management iss based arounnd the anticiipation and p prevention oof potential a adverse environmentaal effects. Th his reduces tthe reliance oon quantitattive monitoriing (which prromulgates a a reactive approach to eenvironmenttal managem ment) and willl ensure the e CRL meets tthe requirem ments of the RMA which aims to avoid, remedy or mitigate advverse environnmental effe ects.

The approach h adopted byy this EMF aim ms to providde greater ce ertainty to all parties, wh ile retaining a degree of flexibility in acknowledgin ng the need tto adapt andd respond to changing cirrcumstancess. The proacttive id dentification of potentiall adverse effe ects throughh the EMF process will en nable the releevant parties to agree in n advance the b best solution ns to addresss known issu es and effects, and provides a clear fframework to address other future issues and efffects as theyy arise.

As noted abov A ve, the EMP (drafted and d administerred by AT) will establish tthe environm mental param meters within n which the Con w ntractor will have flexibility. Exactly how these risks, issues a and effects w will be mitiga ated and/or then be add managed will m dressed laterr in the Consttruction Envvironmental M Managemennt Plan (CEMP) and Delivery Work D k Plans (DWP Ps). The CEM MP and indivvidual DWPs will be drafted and admiinistered by Contractors, and approved d by AT. Thiss is considere ed to be an aappropriate aand flexible approach whhich will help p facilitate th he most effective m e solutions b being implem mented to deeliver on the CRL’s projecct parameterrs.

Environmentaal management is a component of thhe CRL from tthe initial de esign stage riight though tto on‐going operation. Ass at August 2 2012, the CRL has progreessed through to the concept design sstage and th he EMF has been develop ped to suppo ort this. Deta ail around th e design and d actual consstruction meethodologies will follow in n su ubsequent d design and co onstruction sstages. The EEMF approacch outlined in this reportt allows the project’s environmentaal management aspects tto evolve, reefine and devvelop in para allel with thee project itself. ove will ensuure that relevvant knowledge and infoormation is ccarried The linked serries of plans outlined abo fo orward throu ugh the projeect (e.g. any designation or early resource consent requiremeents are kno own to futuree CRL operation nal managers).

Finally, the reegular review ws and evolviing nature off the EMF’s kkey documen ntation will eensure that tthey reflect aall uture statuto ory authorisaations and ap pprovals, andd are an up‐tto‐date key rresource for all project p participants. fu

Deveelopment of a ‘mitigation h ierarchy’, a caascading serie es of actions w where: o Impacts a are to be avoi ded or reduce ed at source, w where possiblle, designing tthe project so o that the imppact is avoided d in the first p place; o Mitigation measures a re to be included in the pro oject to reducce the adverse e impact w where it has noot been practiicable to avoid d or reduce thhat impact at source; o For those e adverse imp acts that still remain signifiicant after thee application o of the above e measures, aadditional meaasures are to be taken to avvoid the potential impact or, if not practicable, to compen nsate for it by some other means.

Wheerever possible e, the project will protect h heritage assets within its coontrol. Mitigattion meassures that add dress the poteential impact on built herita age items will need to be considered on a building by buiilding or site b by site basis. T The definition of these meassures will be ffinalised in succcessive refinements as the e project is deeveloped, detailed information on the prooperties becom mes available and the consstruction meth hods are finaliised. There arre, however, aa number of universal mitiggation actions that can be identiffied at an earlly stage and that will be applicable: o Mitigation programmee ‐ An agreed mitigation pro ogramme for the impact on n built heritage will needd to be agreed d and implemented throug h the developm ment of a Heriitage Management Plan prior to the com mmencement of any consttruction workk and monitored during con nstruction as aappropriate. T This will bringg together thee specific mitiggation actions required for specific propertie es. o Relevant planning and other policies ‐ The design n and construcction methods should m meet the requi rements of all relevant stattutory legislattion, codes of practice a and standardss. o Condition n surveys ‐ Coondition surveys will need to o be undertakken to define appropria ate vibration aand settlemen nt limits for historic buildinngs and structure es that may bee potentially aaffected by construction woorks. o Precautio ons ‐ Suitable precautions w will be taken to avoid any uunplanned impacts o on identified hheritage assetts. Where necessary, suitabble screening a and other pro otective meas ures will need d to be erected to protect hhistoric buildin ngs within an nd adjacent too works areas.. o Importan nt features ‐ Sppecific protecctive measures will need to be undertake en where ne ecessary to pr otect the building or its important or valluable heritagge features. Appropriate procedures w will also need to be establisshed for the repair of any damage tto historic buiildings from th he constructioon or operatio on of the CR RL. o Building R Recording ‐ Ann appropriate e level of Build ding Recordingg and publicattion of these iinvestigationss will need to be agreed and d implementeed in a formatt suitable ffor public disssemination. o Dismantling and Reconnstructing ‐ Ap ppropriate pro ocedures will need to be established and agreedd for any dism mantling or re‐‐erection of ceertain historicc buildings and other hisstorical structures tempora arily or perma nently affecte ed by the wo orks. o Adaptive Reuse – Any proposal to siignificantly altter or demolissh heritage buildings or structuress should be baased on a full jjustification a nd exploration of all possible alternat ive options avvailable, includ ding their reteention, adaptive

Salvage SStrategy ‐ A suuitable set of p procedures will need to be established and agreed fo or the removaal, storage and d for later refitting/reuse off elements fro om certain historic buildinngs and other historical stru uctures. o Interiors ‐ Suitable preecautions shou uld be put in p place for the pprotection of more sen nsitive interiorrs. o Setting ‐ T The success oof any proposaal to alter the historic envirronment is like ely to be measured by its relationship to the context that it is partt of. o Context ‐‐ Deep knowleedge and a tho orough underrstanding of thhis context should fo orm part of thee design process. o Vacant Buildings Proceedures – Proce edures should d be establisheed and agreed d for the m management aand maintenan nce of historicc buildings thaat may be leftt empty du uring construcction, until succh times as these buildings are subseque ently occupiedd or disposed of. o Method sstatements ‐ M Method statements will be required for certain speciffied works and will be subm mitted to the local planning g authority forr its approval,, as well as NZHPT where rrequired; o Enhancem ment of publicc appreciation n – The CRL prresents an op portunity to improve tthe built envirronment arou und existing heritage buildinngs, and also (through presentation and interprettation) an opp portunity to e ducate the general p public on theirr city and heritage. These actions may reesult in higher levels of public apprecciation and perceived value of the city’s hhistoric environm ment.

Effeccts on subsurfface archaeoloogy can only b be confirmed once works arre underway and can b be appropriately mitigated under the Hisstoric Places A Act 1993. Mittigation optio ons/actions include: HPT prior to the o Obtainingg an authorityy to modify arrchaeological ssites from NZH start of co onstruction w works so that p processes can be put in pla ce for any archaeolo ogy that may be exposed during construction; o Preparatiion of an Archhaeological Management Plan setting ouut requiremen nts and proce edures for arcchaeological m monitoring of preliminary eearthworks in areas of a archaeologicaal potential, th he accidential discovery of aarchaeologica al remains a and recordingg any archaeological evidence before it iss modified or destroyed d; o Any archa aeological rem mains exposed d during the cconstruction oof the CRL sho ould be investigated and re corded (unde er authority fro om NZHPT) too add to our understanding of 19th ccentury Auckland. o
