The EIA process:




screening - to decide if and at what level
EIA should be applied
scoping - to identify the important issues
and prepare terms of reference
impact analysis - to predict the effects of a
proposal and evaluate their significance
mitigation - to establish measures to
prevent, reduce or compensate for impacts

reporting - to prepare the information
necessary for decision-making
review - to check the quality of the EIA
report.
decision-making - to approve (or reject)
the proposal and set conditions
follow up – to monitor, manage and audit
the impacts of project implementation
public involvement - to inform and consult
with stakeholders

Public involvement
Project Screening - is an EIA needed?
Scoping – which impacts & issue to consider?
Description of the proposed action
Identification of key impacts
Assessing: Prediction of impacts
Evaluation & assessment of significant of impacts
Identification of mitigation measures
Presentation of finding in an EIA report (EIS)
(including a non-technical summary)
Review of the EIA report (EIS)
Decision-making
Post-decision monitoring
Auditing of predictions and mitigation of measures

Important
Steps in the EIA Process

EIA process
I. Screening
EIAScreening5(Gajaseni, 2007)

SCREENING
 Definition:
–is the process of determining
whether or not a proposal
requires full-scale EIA and the
level at which that assessment
should occur.
EIAScreening5(Gajaseni, 2007)
8
The purpose of screening
The purpose of screening is to determine:
whether
or not a proposal requires an
EIA
what
level of EIA is required
EIAScreening5(Gajaseni, 2007)
9
Outcomes of screening
 full
or comprehensive EIA required
 more
limited EIA required
 further
study needed to determine EIA
requirement
 no
further requirement for EIA
EIAScreening5(Gajaseni, 2007)
10
Screening and scoping
compared
Screening
determines the requirement for EIA
establishes
the level of review
necessary
Scoping
identifies the key issues and impacts
establishes
the terms of reference
EIAScreening5(Gajaseni, 2007)
11
Requirement of full-scale EIA
involves:
 exploitation
of natural resources
 infrastructure
 industrial activities
 extractive industries
 waste management and disposal
 substantial changes in farming or
fishing practices
EIAScreening5(Gajaseni, 2007)
12
Screening methods
 legal/policy
definition
 inclusion
list of projects (with or
without thresholds)
 exclusion
 criteria
list of projects
for case-by-case screening
EIAScreening5(Gajaseni, 2007)
13
Approaches to screening
involve one or a combination of:
discretion
 initial environmental examination
 project lists with/without thresholds
 exclusion lists
 decision-makers’
EIAScreening5(Gajaseni, 2007)
14
EIAScreening5(Gajaseni, 2007)
15
Decision-maker’s discretion:
the proposal itself and its potential impacts
 the level of confidence in the predicted impacts
 the characteristics of the receiving environment
and its resilience to change
 the existing planning, environmental
management and decision-making framework
 the degree of public interest likely in the
proposal

EIAScreening5(Gajaseni, 2007)
16
Initial environmental
examination (evaluation)





describe the proposal and examine any alternatives
that might improve the environmental outcomes
identify and address the concerns of the local
community
identify and assess the potential environmental
effects
mitigate adverse effects and enhance potential
benefits
contain environmental monitoring and management
plans
EIAScreening5(Gajaseni, 2007)
17
Project lists: establish a set of
specific criteria that can be used to
determine which projects will
undergo EIA.
 requiring
full-scale EIA
 requiring some form of further
environmental analysis
 not requiring any further environmental
analysis
EIAScreening5(Gajaseni, 2007)
18
Exclusion lists:
 The
use of exclusion lists is not a
common approach to screening.
 The
use is that the greater number of
smaller and less significant projects
are given exemption from EIA based on
project type or size.
EIAScreening5(Gajaseni, 2007)
19
Thailand:
Type and sizes of projects or activities
requiring EIA report.
 1.
Industry
 2. Residential building and
service
community
 3. Transportation
 4. Energy
 5. Water resource
 6. Watershed area
 7. Mine

Lists of actions:
 Utilising
of positive/inclusive nature
 Utilising of negative/exclusive nature
 Weakness
of lists based on types of
action without considering to
– size
– technology
– resource requirements
– waste characteristics
EIAScreening5(Gajaseni, 2007)
22
Three possible outcomes of
screening process:
 1.
proposals which do not require
additional environmental investigation
because it is expected that they will not
have significant impacts
 2.
proposals which require a limited
environmental study because the
environmental impacts are known and
can be easily mitigated
EIAScreening5(Gajaseni, 2007)
23
 3.
proposals which require EIA to
determine the extent and magnitude of
range of significant adverse impacts
and to propose a range of appropriate
mitigation, monitoring and management
measures
EIAScreening5(Gajaseni, 2007)
24
Ex: Egypt
 3 lists
of project criteria;
– 1. White list
No
EIA requirement
– 2. Gray list
Scoped
EIA study may be required.
– 3. Black list
Full
EIA study is required.

A framework for screening
Mandatory EIA
Increasing impact of
development
‘Inclusive’ threshold
Case by case
consideration of
requirement for
EIA
EIA more likely to be
required; screen
borderline proposals for
significant environmental
effects
‘Indicative’ threshold
EIA less likely to be required
but still screen for significance
where the location is sensitive
or if there is a potential for
cumu
EIA ruled out
Exclusive threshold
