\section{Background}

\subsection{Environmental Impact Assessment}

The term ``Environmental Impact Assessment'' (EIA) is used to refer to
a set of standardised procedures that are designed to inform the
decision-making processes surrounding development proposals. According
to the International Association for Impact Assessment (IAIA), a major
objective of EIA is to ``anticipate and avoid, minimize or offset the
adverse significant biophysical, social and other relevant effects''
of such proposals ``prior to major decisions being taken and
commitments made'' \parencite{principles}.

% TODO: sustainable development

In order to provide decision-makers with sufficiently detailed insight
into the potential positive and negative effects of a project on the
environment, the participation of all parties that would be affected
by the project, as well as the participation of the general public is
explicitly encouraged \parencite{principles}.  The involvment of the
public in the decision-finding process is a crucial component of EIA
as those responsible for the project proposal and the prediction of
its impacts on the social and natural environment do not necessarily
share the values of affected communities.  Hence, public participation
can provide balance to the biases of developers and the assessors they
hire \parencite{wilkins}.


\subsubsection{EIA activities and procedures}

The EIA process generally involves the following
activities \parencite{principles}:

\begin{enumerate}
  \item[\emph{Screening and scoping.}]

    The goal of the \emph{screening} step is to limit the application
    of EIA procedures to those projects that are expected to have
    significant effects on the environment.  What kind of projects require
    an impact assessment varies from country to country. When a proposal
    is subject to EIA, the \emph{scope} of the assessment is determined by
    identifying the key impacts that are associated with the project.

  \item[\emph{Consideration of alternatives.}]
    %TODO: important. Spend a little more time on this.

  \item[\emph{Impact analysis, mitigation, and evaluation of residual impacts.}]

    The analysis of impacts and proposed actions to mitigate them is
    one of the major steps in preparing environmental impact
    statements. This step is usually performed by the proponents. How to
    fairly establish the significance of residual impacts (i.e. impacts
    that cannot be mitigated effectively but are also considered to be
    minor) is frequently subject of debates. According to \textcite{wood},
    ``significance evaluation \ldots remains one of the most complex,
    contentious, and least-understood aspects of EIA systems across the
    globe''.

  \item[\emph{Reporting, independent review and decision-making.}]

    A final EIA report is required to contain sufficient information
    to allow for well-informed decisions about the proposed activity.  An
    independent review ensures that the report is of sufficiently high
    quality.

  \item[\emph{Monitoring and other follow-up activities.}]

    It lies in the nature of EIA that predictions about potential
    impacts are fraught with inaccuracies. To improve the often inadequate
    knowledge about the state of the environment and the actual impacts of
    human activities on it, the implementation of many projects subject to
    EIA should be followed by monitoring efforts. Feeding back into the
    process as it applies to future projects, monitoring ideally enables
    decision-makers and assessors alike to produce higher quality
    assessments and approach the ideal of sustainable development.

\end{enumerate}



\subsection{The Resource Management Act 1991}

The Resource Management Act 1991 (RMA) is the overarching
environmental management framework which governs the allocation and
utilisation of New Zealand's natural resources and controls adverse
effects on the environment. The RMA is the result of efforts to unify
and simplify previous legislation relating to environmental management
which had lead to what was perceived as an uncoordinated, complex
network of confusing environmental management
strategies \parencite{twp98}. It consolidated around 70 laws and
statutes and is generally considered to be the first piece of
integrated sustainability legislation in the
world \parencite{rma-guide}.

The RMA has been described as an ``effects-based approach'' to
regulation \parencite{sadler}, as it does not intend to regulate human
activities per se, but ``focuses on the regulation of the effects of
human activities on the environment'' \parencite{furuseth}. Notably,
the RMA makes no reference to EIA or environmental assessment
procedures. As \textcite{sadler} writes, environmental assessment
under the RMA ``operates within the statutory planning and consent
system rather than as a separate procedure, applies explicitly to
projects and is indirectly specified for policy statements and
strategic plans which local authorities are required to prepare to
guide and implement sustainable resource management'' \parencite[p
31]{sadler}.


\subsubsection{The role of sustainable development}

% TODO

%As the concept of sustainable development became more popular
%... scope of project-based impact assessment determined to be too
%narrow to ensure a progression towards sustainable
%development. Strategic Environmental Assessment (SEA) ...

%- broad definition of ``environment'' is adopted
%``Social Assessment'' (Taylor et al in the Green Book, chapter 25)
%
%\begin{quote}
%   The New Zealand Resource Management Act (1991) ... has included
%   mandatory requirements for the assessment of environmental effects,
%   with “social,” “cultural,” and “amenity values” clearly included in
%   the definition of environment. Also required are public involvement
%   and community consultation, and monitoring of effects once the plan or
%   project has begun.

% \begin{quote}
%   It provides a comprehensive framework with a single
%   purpose of promoting “the sustainable management of natural and
%   physical resources” (Section 5).
% \end{quote}


\subsubsection{Decentralised environmental management}

Interestingly and somewhat unusually in international comparison, the
RMA shifts the main responsibility of resource management activities
to local authorities rather than imposing a prescriptive management
style. The role of central government under the RMA is purposefully
limited, allowing district and city councils to let their decisions be
guided by locally determined goals. This devolved mandate---the
distribution of management responsibility from the national to the
regional and finally local level---is intended to ensure that
decisions relating to resource usage are made not only within the
national policy framework but also at a level closest to the resources
in question \parencite[p 27]{miller2010implementing}.

Responsible for the national policy framework within which local
authorities are encouraged to develop local plans and evaluate
resource consent applications is the Ministry for the
Environment\footnote{Since the RMA amendments of 2009, the newly
founded Environmental Protection Authority (EPA) is increasingly
taking over the regulatory functions of the Ministry for the
Environment, which is now focusing on policy and regulation under
environmental acts other than the
RMA \parencite{miller2010implementing}.}. The Ministry is supposed to
prepare and publish national policy statements---declaring governance
intent relating to issues affecting the whole country or in
fulfillment of international agreements---as well as national
environmental standards (specific points of reference in the areas of
air quality, water quality, etc).

According to \textcite{furuseth}, ``among local government units, the
regional councils are presented with the greatest responsibilities and
the most far reaching potential to implement sustainable
management'' \parencite[p 262]{furuseth}. On the regional level,
regional councils are to produce regional policy statements (RPS) and
may also produce more comprehensive and prescriptive regional plans to
support the goal of achieving integrated management of natural
resources. Regional policy statements ``present an assessment of
existing conditions and a direction for resource management in the
region'' and are therefore at the core of the goal to achieving
sustainable development which is implemented through decisions over
resource consents \parencite{furuseth}.  As
\textcite{miller2010implementing} notes, the issues every regional
council has to address in plans and policy statements are mostly
related to the sustainable management of natural or physical
resources. Planning freedom at the district level is largely constrained by the
regional plans and policies. % TODO? one more sentence; subdivision etc done at district level


\subsubsection{Plans and resource consents}

The plans and policies at the national, regional, and district level
provide a framework for regulation of development activities.
%TODO: the evolution of a plan; public participation in the evolution of plans
%TODO: must mention consultation steps in RMA! check miller2010implementing

For every proposed activity that is not explicitly allowed as a
`Permitted Activity' in the appropriate regional or district plan,
resource consent have to be obtained from the local authorities before
development may commence \parencite{fookes}. Every resource consent
application, in turn, requires the proponent to produce an Assessment
of Environmental Effects (AEE); this requirement is most readily
recognisable as an implementation of EIA. The Fourth Schedule of the
RMA is intended as a most basic guide to assist practitioners in
preparing their AEE; beyond the requirements of the Fourth Schedule,
however, there are few guidelines to assess the quality of an
AEE \parencite{miller2010implementing}. After a review of the AEE, the
council that received the resource consent application may decide to
involve the public by means of public notification or determine that
public notification is not required when the activity is expected to
only have minor effects and all affected parties agree on the
proposal \parencite{fookes}. When an application is publically
notified, the application is to be reviewed under consideration of
public submissions and the results of public hearings. Participants in
the public submission and hearing steps may also appeal to the
Environment Court.

EIA in New Zealand under the RMA can thus be said to happen on two
levels: first, during the development of regional and district plans
which are a consultation-heavy implementation of the screening and
scoping steps of standard EIA; and second, in the process surrounding
resource consents, involving the actual assessment of potential
impacts, an independent review, and public participation.
