Developing environmental management systems to deliver mitigation and protect the EIA process during follow up

Developmental projects are dynamic in the manner in which proponents react to issues or events arising during the conceptual planning, design or construction phases. The basic challenge of integrating environmental impact assessment (EIA) into an existing environmental management system (EMS) is to provide adequate control while allowing flexibility to cope with site-specific project requirements. Environmental management plans (EMP) are one way of controlling the environmental effects of construction projects. These contain project-specific protocols that act as an EMS interface between the EIA and subsequent project planning and development phases. This paper developed from the EIA follow-up session of IAIA 2001 in Cartagena, Columbia outlines the framework for an EMP and its application in respect of the development of an electrical infrastructure project within the UK.

Abstract

Impact significance determination lies at the heart of environmental impact assessment (EIA) but conflict and misunderstanding around the concept is common. This paper attempts to make sense of impact significance in EIA based on four essential components of significance synthesised from the literature to ensure that: (1) a clear operational framework for significance determination applies throughout EIA, (2) attention focuses only on significant issues, (3) the term significance is specified and applied consistently, and (4) significance determinations are transparent to all EIA stakeholders. To provide a practical perspective, the extent to which EIA institutional provisions in Western Australia uphold these significance determination components is reviewed. Overall the Western Australian approach generally meets all four components, but areas for improvement include better guidance encouraging proponents to adopt a more consultative approach to determining relevant environmental factors and objectives to better focus EIA, and distinguishing between terms used for significance within EIA documentation. A new significance framework approach in Western Australia represents a clear attempt to uplift practice, but opportunity exists to improve the way impact significance determinations are presented to stakeholders. EIA practitioners may benefit from mapping and making sense of impact significance in their own jurisdiction using the four components presented.     

Development of environmental management program in environmental impact assessment reports and evaluation of its robustness: an Indian case study

The degree of robustness of environmental management program in the EIA reports of 56 green-field and 28 brown-field environmentally approved projects was found to be low, revealing that it is not considered seriously by the EIA consultants and the decision-makers. EMPg, akin to EIA follow-up, specific to a project at a given location, is the most important output of the EIA process especially for the developing countries where priority is on the economic development by way of development projects and the EIA process has inherent weaknesses. A meticulously prepared, implemented, operationalized, monitored, periodically audited and continually improved EMPg in different life-cycle phases of a project could possibly offset limitations of the EIA process. Considering lack of guidelines available on the development of EMPg, elaborate guidelines are proposed. EMPg could be prepared as a separate document to facilitate development of project manual. TOR for brown-field projects need a totally different approach. Amending the currently followed EIA process and introducing an additional stage of mandatory approval of EMPg, and third party audit would improve its robustness.     

Extending environmental management systems principles to environmental assessment: the use of environmental audits

Natural Resources Canada is expanding the application of environmental auditing to fulfill a key requirement of its environmental management system (EMS) as applied to environmental impact assessment (EIA). Such an evaluation progamme requires endorsement and commitment from senior management. It helps to define legal and policy requirements, significantly influences the implementation of the EMS, provides the foundation for examining the management of EIA in an organization, and makes a key contribution to the review and improvement of the EMS. Through its reporting of results to senior management and requirement for action plans, it is anticipated that the Evaluation Programme will contribute to improved EIA practice in the long term.     

HIA practices in Nigeria

Health impact assessment (HIA) provides useful information on existing health services, their capabilities and the health status of the local communities, which is otherwise often unavailable. In Nigeria, HIA is usually applied to projects and, by exposing existing health inequities in project communities, provides the necessary tool for development proponents to act to provide or improve health services and to implement health promotion activities. Based on HIA experience in Nigeria, this paper highlights the deficiencies in national legislation with regards to HIA/EIA (environmental impact assessment) integration and a number of learning points are discussed. First, a complete health baseline is critical to the understanding of project impacts; analysis must be broad-based, considering existing health determinants. Second, community stakeholders and proponents may modify the implementation of health mitigation measures and should be seen as collaborators in the assessment process. Third, strong HIA recommendations can influence project design. A greater participation of the health sector in EIA is required to enhance HIA utilization.     

An integrated building information modelling-based environmental impact assessment framework

The application of Environmental Impact Assessment (EIA) studies faces many challenges, especially in developing countries. This problem was investigated in the existing literature and via a designed questionnaire among local practitioners. The reasons were mainly attributed to the seclusion of the EIA process across the project’s phases, as well as the complexity of the EIA procedures. Hence, the research argues that Building Information Modelling (BIM) applications can be the key to resolve several associated problems to EIA either directly, or indirectly by streamlining Environmental Management System (EMS). Thus, a keyword-based scientometric analysis was used to define parameters and interrelations and establish network analysis for a proposed BIM-based EIA framework. The proposed framework presents scoring schemes to support three types of assessments: the efficiency of applying BIM techniques for an EIA process (Score A), proper integration of BIM techniques for different EIA steps (Score I) and proper integration of BIM techniques across project phases (Score B). It also shows the interplay of points between the three schemes via a Sankey diagram. The proposed framework was applied to compare three major construction projects in a developing country, the case of Egypt to pinpoint areas of drawbacks. The results pinpointed poor application of advanced BIM models to support sustainability analysis for EIA studies. This is in addition to imbalance of applying BIM applications across different project phases, it was notably less pronounced for the operation and maintenance stage as well as end of life scenarios. Also, poor integration of BIM tools could not support decisions related to the mitigation step. Hence, applying 6-dimensional BIM model shall enable developing mitigation measures and shall support design optimization during building operation and end of life phase. This novel approach presents the required level of verification and quality control procedure needed by decision-makers and environmental engineers to perform EIA studies and pave the way for further related research.

A proposal for further strengthening science in environmental impact assessment in Canada

We observe ongoing weaknesses in the quality of science underpinning environmental impact assessment (EIA) in Canada. This is frustrating because approaches for strong scientific practice in EIA were published decades ago. A major failing has been the lack of scientific support from outside the EIA practitioner community. We argue for a re-conception of science associated with EIA that includes a rigorous scholarship of application inside EIA and a vigorous scholarship of integration outside it. Cases of exemplary organizational structures and science applications in the Canadian forest sector are given. To turn EIA from the often bitter battleground of shallow impact debates to an enterprise of strong accumulation of effects knowledge, we urge the relevant communities of researchers and practitioners to become embedded communities of practice and reform the way science contributes to EIA.     

Improving access to biodiversity data for,and from,EIAs – a data publishing framework built to global standards

Biodiversity information obtained during environmental impact assessments (EIAs) is rarely accessible for other uses following the completion of the EIA. Such data need to be made readily accessible; adding them to publicly accessible national datasets is important if biodiversity science, conservation and future decisions based on environmental assessment are to benefit from new biodiversity data and improved biodiversity data coverage. An ‘EIA Biodiversity Data Publishing Framework’, based on the Global Biodiversity Information Facility (GBIF) global standards, is thus proposed to meet this need. This paper outlines the GBIF-catalysed initiative to establish such an operational framework for uptake by the EIA community, as well as options that are available for data publishing in the absence of such a framework. It reviews the current state of accessibility and management of the primary biodiversity data associated with EIA studies, and highlights the urgent need for uptake of a range of data-publishing tools and best practices for making EIA biodiversity data exchangeable using globally accepted standards. Lessons learnt from pilot projects in India and South Africa underline the call for the rapid uptake of a national-to-global scale EIA Biodiversity Data Publishing Framework.     

Public participation in EIA and attitude formation

Although public participation in EIAs aims for public acceptance, it does not guarantee the project (of which the EIA is part) is accepted. Moreover, when citizens participate in EIAs, they develop attitudes towards the project itself, and towards the broader policy. This paper addresses the complex relationship between participating in EIA studies and accepting policies. We first discuss what attitudes can develop towards a project, and how they may influence the perception of the broader policy sector and the attitude towards policy processes. We distinguish four attitudes and show they are present in a dike-relocation case in the Netherlands. We further show that different experiences in the EIA led to different project evaluations and this impacted stakeholders' attitudes to participation, projects and policy-making. We found four aspects of the EIA process of this project that partly explain the arisen difference in project attitudes. These aspects are important to consider in the design and management of participative EIAs.     

Multi-project environmental impact assessment: insights from offshore oil and gas development in Brazil

Despite being adopted worldwide, environmental impact assessment (EIA) is under pressure in many countries, while perceived (rightly or wrongly) as an ineffective and inefficient process. Strategic environmental assessment (SEA) is thought to help address some of EIA’s shortcomings, but it is absent in many jurisdictions and sectors. In this paper, we argue that multi-project EIA can, in some contexts, simultaneously deliver greater effectiveness and process streamlining. To illustrate our claim, we present a case study from offshore petroleum production in Brazil, where the development of the pre-salt giant reserves is being licensed through a multi-project EIA approach, in a non-SEA planning environment. The analysis provides interesting insights on the strengths and challenges of that strategy, focusing on five aspects of practice: cumulative impacts, efficiency, approach to authorizations, follow-up and political issues. Proper scoping was found to be essential to consistent EIA processes and shorter review times. Finally, we suggest that multi-project EIA approach should be revisited by practitioners and regulators to identify opportunities for deployment, especially in jurisdictions where strategic assessments are not in place.     

Project splitting in environmental impact assessment

Abstract

This paper discusses project splitting in environmental impact assessment (EIA), investigating the current state of knowledge through literature, legislation, case-law and practice, discussing problems and providing solutions. The focus is on Spain, but many of the conclusions are applicable worldwide. Project splitting is a much more common practice than generally accepted. The main efforts have been focused on preventing salami-slicing as a mechanism to avoid the EIA, but it is a much more complex problem, with different ways of splitting and reasons for doing so. Measures to avoid this practice should include strengthening the strategic environmental assessment, a greater involvement of the approval authority, specific prohibitions in regulations, using case-by-case examinations instead of thresholds, compulsory scoping and avoid the exclusion of project parts during the EIA.     

Assessing the utility of environmental factors and objectives in environmental impact assessment practice: Western Australian insights

Environmental factors and objectives are formally identified during the scoping stage of environmental impact assessment (EIA) to structure and focus individual assessments. Environmental factors are broad components of the environment, while objectives set the desired outcome for a specific factor. This research assesses the utility of environmental factors and objectives in EIA practice based upon a combination of literature review and interviews with 21 EIA practitioners from Western Australia. Further to providing focus and structure for EIA, practitioners also use environmental factors and objectives for decision-making throughout the process. The majority of practitioners also note that factors and objectives are value adding and useful to their EIA practice. Due to their inherent subjective natures, interviewees noted a lack of consistency regarding how to meet the objectives and challenges in determining the significance of impacts on a factor. Identified opportunities to enhance use of objectives and factors in EIA included provision of more guidance, especially criteria or standards to apply and improve knowledge sharing between EIA stakeholders.     

Environmental impact assessment (EIA) screening and scoping of extraterrestrial exploration and development projects

Numerous space missions are planned by government agencies and private companies, with objectives including scientific research, prospecting for and mining resources, and establishing human settlements. These projects have potential to affect the extraterrestrial environment. Environmental impact assessment (EIA) is an important tool for assessing the potential impact of projects on Earth’s environment. However, the legal requirements to undertake EIA for extraterrestrial projects are limited and most EIAs that have been conducted have not considered impacts beyond Earth’s atmosphere. Technical barriers to extraterrestrial EIA also need to be overcome, including a lack of guidelines and methodologies. This paper addresses the latter issue by identifying the extraterrestrial impacts that may arise from space projects and relating them to the environmental topic areas in the European EIA Directive. An example is then provided of how EIA screening and scoping can be undertaken for the extraterrestrial elements of space projects, using six scenarios. Effective EIA screening and scoping is key to deciding whether EIA is required and if so which topic areas should be included.     

IAIA'99

The provision of environmental impact assessment (EIA) guidance is generally claimed to be beneficial for improving practice through local capacity building. However, to date no studies have investigated their effectiveness. In Western Australia, EIA guidance materials are intended to allow for better environmental protection; increased certainty; enhanced consistency of advice given to Government; proposals to be designed to meet environmental objectives from the outset; and to provide a clearer basis for Government decision-making. Twenty practicing environmental consultants were interviewed about the effectiveness of guidance materials at achieving these objectives. It was found that EIA guidance influenced the practice of consultants and was perceived as effecttive in enhancing the outcomes of the EIA process overall. However, a number of shortfalls were identified. Suggestions are made for increasing the utility of future guidance materials thereby enhance the effectiveness of EIA practice itself.     

Carbon definitions and typologies in environmental impact assessment: greenhouse gas confusion?

Estimation of emissions of greenhouse gases (GHG) is becoming an established part of assessing sustainability within environmental impact assessment (EIA). However, a comparative study of 25 environmental impact statements (EISs) to analyse the practice of accounting for emissions during the EIA process suggests that consideration of the effects of development on emissions of GHG is poorly understood. The extent to which assessment is actually carried out is also inconsistent and sporadically implemented. A key indicator appears to be the varying and sometimes contradictory use of technical terminology, particularly of the term ‘carbon’ and its similar phraseology. This paper provides a critical evaluation of the differing terminology that is applied to GHG assessments undertaken as part of EIA process and explores the effect that misuse of these terms could have on an impact EIS.     

Closing the regulatory gap: revisions to the conventional practice of ex-post plans for EIAs to protect the valued components of Aboriginal peoples in Canada

Aboriginal peoples have distinct perspectives and relationships with the terrestrial and aquatic settings and components that sustain cultural modes of life. Valued components derived from these cultural understandings are to be incorporated into environmental impact assessments (EIA) that occur in their respective territories. Despite this technical and legal basis, Aboriginal cultures are often inadequately accounted for in many ex-post plans of development activities and projects. This paper examines changes made to the regulatory requirements of an ex-post plan that involved Aboriginal peoples and a pipeline project located in north-east British Columbia, Canada. The research context and the revisions made to the conventional practice are presented, followed by a discussion of the possible broader implications for future EIAs. The study provides useful insights into the deficiencies of conventional practices and contributes to technical understandings in terms of integrating and protecting Aboriginal cultures through ex-post plans.

The environmental impact assessment (EIA) system in Uzbekistan was inherited from the USSR and is centred on state environmental review, a procedure for reviewing the impacts of proposed activities by environmental authorities. This is proving to be a less effective tool of environmental protection in the new political and economic conditions. Since the collapse of the USSR, the Uzbekistani EIA system has undergone gradual reform but the national EIA system remains almost identical to the ‘socialist’ system. At the same time, some elements are similar to those of EIA systems used in developed countries. The shortcomings of the system include unclear screening provisions and lack of public participation. The paper analyses strengths, weaknesses, opportunities and threats for the development of EIA in Uzbekistan, taking into account various political and economic factors.     

Great differences in the ways of implementing the new EIA Directive – the offerings of the EIALAW 2018 conference

On the 23 March 2018, the most recent developments of the environmental impact assessment (EIA) law were examined by experts in Helsinki. The main theme of the conference was the comparison of the implementation experiences of various countries concerning the reformed EU EIA Directive. The European EIA debate was reflected against experiences in Canada. This paper examines the key points of the conference presentations and the lessons of the event.     

Emergy-based life cycle assessment (Em-LCA) for sustainability appraisal of infrastructure systems: a case study on paved roads

Civil infrastructure systems are critical assets that are subjected to damage, service-life deterioration, and increasing maintenance and rehabilitation cost. Effective infrastructure management and principles of sustainable development can help to find an optimal compromise between economic growth and environmental protection for all stakeholders. Colloquially, sustainability refers to meeting triple-bottom-line (TBL) performance objectives including environmental protection, economic prosperity, and social acceptability and equity as a result of short- and long-term policy decisions. In this paper, a comprehensive framework based on the integration of emergy synthesis and life cycle assessment (LCA) has been investigated for a public infrastructure system. The main purpose of the applied method, emergy-based LCA (Em-LCA), is to facilitate an informed decision making process for different asset management scenarios, by identifying and quantifying the attributes of TBL impacts over the life cycle of a civil infrastructure system. As a case study, Em-LCA framework has been applied to evaluate the sustainability of two different scenarios for a road construction project in interior British Columbia, Canada. The results indicate that Em-LCA offers a good understanding to address sustainability issues in infrastructure systems and provides quantitative and transparent results to facilitate informed decision making for asset management.     

Environmental indicator frameworks to design and assess environmental monitoring programs

Monitoring is fundamental to environmental impact assessment (EIA) both to assess adherence to standards and to support management options. The use of indicators assures that a monitoring program addresses only the key variables associated with significant environmental impacts and also improves monitoring communication and reporting processes. This paper develops a conceptual framework to design and assess an environmental post-decision monitoring program under EIA procedures - INDICAMP. It also discusses how current indicator frameworks can be used to design and evaluate the performance of environmental monitoring programs in projects. A coastal infrastructure case study demonstrates the usefulness of this methodology.
