Introduction – EIA quality
What makes a good EIA and, consequently, a good environmental
statement (ES)?
What are the challenges that the EIA practitioner faces in meeting
expectations and delivering quality?
What can we do to help improve quality?

What makes good quality EIA ES?
Early engagement
Thorough scoping
Good background research
A sound and up-to-date EIA
A focus on the important issues
Cohesion through good conclusions
Concise – matters of significance
Useable as a balanced guide for those who know as well as those who do not
Clarity for decision makers, especially on key issues that could decide a case
Well laid out – chapters all edited by the same person to make navigation
around the document easier rather than having lots of different authors with
different styles
Transparency, especially in explaining uncertainty and providing confidence in
predictions

However…
Many EIA ESs have become large, cumbersome and
unwieldy documents. Feedback from stakeholders reveals
that this often makes them inaccessible.
Scottish Natural Heritage recently reviewed 12 EIAs and
concluded that 11 were of poor quality.

Why?
Insufficient resources
Unreasonable timescales set by the developer
The changing nature of a development
Lack of an available baseline and/or unknown likely impacts
Lack of a clear steer at the screening and scoping stages
Assessment of impacts is poor, in particular, cumulative impacts, relationships
between topics and the lack of an overall summary of impacts

Planning Advice Note (PAN) 1/2013
The Scottish government has prepared PAN 1/2013 on EIA to provide guidance
on how practitioners should be encouraging proportionate and efficient EIAs by
focusing resources on the significant issues and how the project proposes to
mitigate adverse effects.
EIAs should be
Clear and concise
Consistent
Proportionate

IEMA EIA Quality Mark
RSK Environment Ltd (RSK) is one of
only 49 IEMA EIA Quality Mark
registrants across the UK.
RSK has made a voluntary
commitment to excellence in its EIA
activities ranging from managing the
process and maintaining staff
capabilities to effective presentation of
assessments findings and taking
action to improve practice.
Under the EIA Quality Mark scheme,
RSK is audited annually by IEMA to
confirm that its ESs and EIA processes
fully satisfy IEMA’s requirements.

Solutions
How can consultants improve the quality of the iterative
EIA process?

Integrating spatial data across the project
Project development can take years from feasibility through to application
submission. This can lead to the accumulation of hundreds, if not thousands, of
requirements arising from government and client targets and objectors.
Question
How can quality be maintained through the life cycle of a project?
Solution
Bring ESs into the 21st century using GIS and integrating spatial data across the
life cycle of the project, thereby minimising the risks and providing spatial project
information to decision makers and key stakeholders

Project life cycle
The development of a GIS-
based data management
tool will provide return on
investment throughout a
project’s life cycle.
The same tool can be
expanded to include
functionality specific to a
particular stage in the life
cycle.
A strong foundation of
robust data management
processes and data
standards is essential for
making the system work.

Web-mapping via ArcGIS Online
Data sharing: ArcGIS Online is used to share geospatial information with
extended project teams (RSK staff, client engineers, planners, project managers,
joint-venture members, etc.)

Summary
Key benefits
All parties working with the most up-to-date information, design and collected
data
Reduces risk of unknown historical project information (all centrally stored)
Accessible to all key stakeholders, but with different levels of security to ensure
only relevant information is given to each interest group
Location specific, focuses on the important issues
Provides links to relevant documents supporting information
Reduces waffle, as it is map based and concentrates on the important issues
