Road Developments in the UK: An Analysis of Ecological Assessment in Environmental Impact Statements Produced between 1993 and 1997

Environmental impact assessment (EIA) has been required for certain proposed road developmentsin the UK since EC Directive (85/337) was implemented in 1988. The extent to which the requirements of the EIA Directive are met with respect to ecological issues has been explored in earlier reviews of road statements (Treweek et al., 1993) and of UK environmental impact statements (EISs) in general (Thompson et al., 1997). This paper describes the results of a further review of 40 EISs produced between 1993 and 1997 and also examines recent changes in the political context for EIA of proposed road developments,including developments in UK transport policy and the UK biodiversity process. The results of the review suggest that the ecological assessment of proposed road developments has improved in some respects, but also highlights the persistence of many shortcomings identified in earlier reviews. The reasons for ongoing failure to address these issues are explored. Key findings include a marked improvement in the extent of reference to consultation with statutory consultees and an increase in the proportion of EISs reporting the results of new ecological surveys. However, while potential ecological impacts were discussed in all the EISs reviewed, many still failed to predict the full range of potential ecological impacts.     

Socio-economic Impacts: Are They Still the Poor Relations in UK Environmental Statements?

This paper discusses the treatment of social and economic impacts within UK environmental impact assessment (EIA). Socio-economic effects have an uncertain status in EIA, guidance on their assessment is limited and their treatment is often partial and of poor quality. This has led some commentators to view socio-economic impacts as the 'poor relations' in EIA. The paper presents the results of a recent review of the socio-economic component of UK environmental statements (ESs), which provides information on the extent, scope, balance and quality of socio-economic impact treatment. The review reveals that, although most ESs include some information on socio-economic issues, coverage tends to be narrowly focused on a small number of--primarily beneficial economic--impact types. Quantification of socio-economic impacts is also rarely attempted. The review findings are compared with those of similar studies undertaken in the mid-1990s, and the paper concludes with some recommendations for EIA practitioners relating to the treatment of socio-economic impacts.     

The typography of environmental impact statements: Criteria,evaluation, and public participation

Guidelines for implementation of the National Environmental Policy Act state that environmental impact statements (EISs) shall use “appropriate graphics.” We examined one component of graphics, typography, identifying applicable criteria from the literature and applying them to 150 EISs prepared by seven agencies. We found that the EISs ranged widely in typographic quality. The average EIS met fewer than seven of ten criteria; 12% were considered unreadable. The results suggest that weak typography may seriously limit public review of EISs. Agencies are encouraged to make typography a serious component of their public participation programs.     

A Critical Review of Environmental Impact Statements in Sri Lanka with Particular Reference to Ecological Impact Assessment

This article critically reviews environmental assessment (EA) practices in Sri Lanka, with a particular focus on ecology. An overview is provided of the domestic and international influences which have shaped the administrative process which is currently a two-tiered scheme. An Initial Environmental Examination (IEE) provides a preliminary screening tool, prior to the requirement for a full Environmental Impact Assessment (EIA). A comprehensive survey of Sri Lankan national archives showed that 463 EAs were completed in the period 1981–2005, with the bulk of these in the more populated Western and North Western Provinces. Two-thirds were IEE surveys, while the remaining third advanced to full EIA. A representative sample of 130 EAs (both IEEs and full EIAs) spanning a broad range of project types, scales, and environmental settings was selected to evaluate the quality of the ecological investigations within the published environmental impact statements (EISs). These were assigned into five classes of “explanatory power”, on the basis of their scientific content in relation to survey, analysis, and reporting of ecological interests. Within most EISs, the ecological impact assessment (EcIA) was restricted to the lowest two categories of ecological assessment, i.e., tokenistic presentation of reconnaissance-level species lists without further analysis of the development implications for individual organisms or communities. None of the assessments reviewed provided statistically rigorous analysis, which would be required if ecological impact studies are to include quantitative and testable predictions of impact, which could then be followed up by appropriate post-impact monitoring programs. Attention to key local issues such as biodiversity or ecosystem services, which also have strong social dimensions in the developing world, was also notably underrepresented. It was thus concluded that despite the existence of a sound legislative framework in Sri Lanka, the analysis contained within EISs generally fails to convey meaningful information to the relevant stakeholders and decision makers involved in protecting ecological interests and promoting sustainable development. The introduction of strategic environmental assessment (SEA) is considered an important tool to strengthen the institutional capacity of Sri Lankan government to implement current regulations and, in particular, to combat the cumulative effects of incremental development.     

Use of Animal Species Data in Environmental Impact Assessments

Environmental Impact Assessments (EIAs) should ideally help minimize adverse effects on biological diversity by considering impacts of projects on wide ranges of species. This paper investigates how recent Dutch EIAs included the species comprising animal diversity. We present results of two studies on fauna data used in the EIAs. Objectives were to determine for different taxa (a) the relative representation of species in Environmental Impact Statements (EISs); (b) the extent to which EISs referred to specific species and the accuracy of survey data referred to; and (c) apparent roles of different EIA actors in species inclusion. EIAs were found to use data on various taxa but on limited numbers of species. The frequency with which taxa were included varied significantly. Birds were most frequently included, followed by mammals, amphibians, and other species groups. The quality of data on birds exceeded that regarding other vertebrates. Our results indicate that (a) EIA working groups of independent experts were the most influential in determining the data to be used; (b) on average, proponents included data more often than required by guidelines; and (c) in 30 to 40% of the EIAs, the participation of nongovernmental organizations prompted use of data. Despite the key role of experts in data inclusion, the taxon rankings found in the EIAs showed little deviation from those observed in studies on people’s preferences for species. Given the limited ranges of species considered, it is doubtful that the EIAs examined effectively contributed to conserving animal species diversity.

Discretionary Judgement in Local Planning Authority Decision Making: Screening Development Proposals for Environmental Impact Assessment

Screening is a critical decision-stage in the Environmental Impact Assessment (EIA) process and involves the determination of whether or not a development proposal will require EIA. This decision requires a discretionary judgement on whether the development has the potential to cause ‘significant environmental effects’, and consequently there is potential for diversity to exist in formal requests for EIA. Drawing upon a comprehensive survey of Local Planning Authorities (LPAs) in England and Wales, this paper explores the characteristics of LPA screening decision making since the introduction of revised EIA regulations in March 1999. The paper starts with a theoretical overview of rationality, decision making and planning theory, followed by a brief review of the regulatory context of EIA screening. The research approach is then outlined and the survey findings are presented, including a detailed consideration of organizational and individual level analyses set within the context of planning theory judgement debates. Comparisons with other European countries are briefly made, before drawing conclusions and recommendations.     

Institutional frameworks to direct development and implementation of great lakes remedial action plans

Locally designed, institutional frameworks are being used to develop and implement remedial action plans (RAPs) to restore beneficial uses in 43 Great Lakes areas of concern. A 1993 Canada-United States roundtable was convened to learn from case studies and to develop recommendations regarding essential characteristics of RAP institutional frameworks, guidance to ensure linkages to other related plans, and ways of embracing new institutional frameworks from RAP development to implementation. Major roundtable recommendations are: (1) RAP institutional frameworks should be empowered to pursue their mission of restoring uses. Empowerment would be demonstrated by: a watershed focus, inclusive and shared decision-making, clear responsibilities and sufficient authority, creative funding capability, flexibility and continuity in the process, an iterative process of continuous improvement, and commitment to education and outreach. (2) RAP institutional frameworks should be used as mechanisms to coordinate programs at the local level. Such local coordination should be complemented with governmental commitments to intra- and interagency coordination in work plans. (3) RAP institutional frameworks can help build the capacity of governments to achieve their goals. Therefore, governments must adopt long-term, visionary goals and commit to a customer-driven RAP process of continuous improvement.     

Environmental impact assessment: An international evaluation

Experiences with environmental impact assessment (EIA) in a number of countries are discussed in the light of both explicit and implicit goals and objectives. Adequate environmental information is not always available to decision makers because of failure to apply EIA to all relevant decisions, the continuing inadequacies of prediction and evaluation techniques, the failure to consider alternatives adequately, and the bias of some EISs. EIA frequently results in changes to proposals and may result in stricter environmental management conditions in some cases, but some people regard it as a failure because it has not stopped development. Generally, EIA leads to better integration of environmental factors into project planning. Open procedures and freedom of information encourage responsiveness to EIA procedures, which can be weakened by discretionary powers and lack of access to the courts by public interest groups. However, legal standing may have side effects that offset its advantages. EIA can encourage cooperation and coordination between agencies but does not ensure them. Similarly, it can have a limited role in coordinating interstate and international policies. In the long term, the success of EIA depends on adequate monitoring, reassessment, and enforcement over the life of the project. EIA has generally opened up new opportunities for public participation, and may help to reduce conflict. EIA procedures need to be integrated with other environmental protection and development control programs, and various means exist for reducing its cost to developers and the public.     

EIA,Decision-making Theory and Screening and Scoping in UK Practice

As an aid to decision making Environmental Impact Assessment (EIA) is seen as a rational and systematic process which is often held to be holistic and proactive in its approach to environmental protection (Glasson et al., 1999). The roots of EIA are firmly located within the 1960s' demand for a more systematic and objective approach to environmental decision making and hence within the rationalist model of decision making theory. This paper examines the key stages of the EIA process to assess how far EIA conforms to the rationalist model today. Most research in EIA decision making has focused on the project authorization process and not the crucial decisions made at the earlier stages of screening and scoping. This study examines those early stages within the context of UK EIA practice. From this examination the paper attempts to locate EIA within decision-making theory.     

Ten Years On: An Empirical Analysis of UK Environmental Statement Submissions since the Implementation of Directive 85/337/EEC

Regulations to implement Directive 85/337/EEC have been in operation in the UK for over 10 years. Implementation of the amended Directive (97/11/EC) in March 1999 marked the start of a new phase in environmental impact assessment (EIA), and so a review of the impact of the original Directive upon EIA activity is timely. This paper examines the implementation of the Directive in the UK through an empirical analysis of the publication of environmental statements (ESs) between July 1988 and April 1998. ES submissions are analysed under Annexes I and II of the Directive and under the main UK regulations, and then development control decision outcomes are considered. The implications of selected legislation and policy initiatives for ES submissions are then investigated in detail for four types of project. The Directive has been a major force in stimulating the development and growth of EIA in the UK, although the interaction of policies and legislation (environmental and otherwise) can exert an important influence upon trends in ES submissions.     

Effects of Impervious Area and BMP Implementation and Design on Storm Runoff and Water Quality in Eight Small Watersheds

The effects of increases in effective impervious area (EIA) and the implementation of water quality protection designed detention pond best management practices (BMPs) on storm runoff and stormwater quality were assessed in Gwinnett County, Georgia, for the period 2001‐2008. Trends among eight small watersheds were compared, using a time trend study design. Significant trends were detected in three storm hydrologic metrics and in five water quality constituents that were adjusted for variability in storm characteristics and climate. Trends in EIA ranged from 0.10 to 1.35, and changes in EIA treated by BMPs ranged from 0.19 to 1.32; both expressed in units of percentage of drainage area per year. Trend relations indicated that for every 1% increase in watershed EIA, about 2.6, 1.1, and 1.5% increases in EIA treated by BMPs would be required to counteract the effects of EIA added to the watersheds on peak streamflow, stormwater yield, and storm streamflow runoff, respectively. Relations between trends in EIA, BMP implementation, and water quality were counterintuitive. This may be the result of (1) changes in constituent inputs in the watersheds, especially downstream of areas treated by BMPs; (2) BMPs may have increased the duration of stormflow that results in downstream channel erosion; and/or (3) spurious relationships between increases in EIA, BMP implementation, and constituent inputs with development rates.     

Development and Implementation of Strategic Frameworks for Air Quality Management in the UK and the European Community

The UK and the EC have recognized that the application of national and EC policies alone may not be cost effective in improving air quality in some areas, especially in traffic-congested urban centres and along major road transport corridors. Consequently both have introduced new strategic frameworksfor air quality management.This paper outlines and compares the UK National Air Quality Strategy (NAQS) and the EC approach, set out in the Air Quality Framework and Daughter Directives. Both frameworks shift responsibility for reviewing, assessing and managing air quality on to local authorities. The UK considers the NAQS will provide the principal means of carrying out its commitments under the new EC framework.Local authorities in the UK have begun the review and assessment phase of the NAQS. This paper examines the support that central government has had to provide to local authorities to ensure the NAQS will be effective. It offers insights into what other Member States are likely to face when implementing their interpretation of the EC air quality management framework. The paper highlights that many UK local authorities lacked even basic air quality management capabilities when the NAQS was being formulated. Consequently the UK Government has had to expand the national pollution monitoring networks (this was achieved primarily by affiliating the growing number of local authority funded sites), commission new detailed urban emissions inventories, and develop and validate a suite of air quality dispersion models. Training events in air quality assessment techniques have had to be offered and many detailed guidance notes issued to ensure an appropriate and consistent interpretation of the NAQS. Some government initiatives to support the implementation of the NAQS suffered delays which initially caused some unnecessary uncertainties and inconsistencies amongst local authorities conducting their review and assessment of air quality. This points to the importance of the Governmentensuring that the support for the management phase of the NAQS will be in place in time. This includes providing additional pollution-control powers and reformulating transport and planning policies in order to integrate air quality management more fully.     

Policy And Practice Environmental Assessmentand Planning: A Chronology of Development in England and Wales

The development of regulations to implement Environmental Impact Assessment (EIA) in England and Wales occurred initially as a response to European Community Directive obligations. Since then, a proliferation of regulations has resulted from the need to meet those obligations which were not covered successfully by the first tranche of legislation; the desire to extend the range of project types requiring EIA beyond those specified in the Directive; and the need to respond to changes brought about by privatization.As a result, current regulations relating to EIA are extremely complex and are in a constant state of flux. This inevitably causes problems for those responsible for their implementation. Ten years after the 1985 Environmental Impact Assessment Directive was notified to the Member States, it has undergone a review and the European Commissionhas reached a common position on the proposedamendments.The implementation date for Member States to meet the requirements of the amended Directive is 31 December 1997 (ENDS, 1996). However, the 1985 Directive has yet to be fully implemented in the UK.     

The role of environmental impact assessment in coal production and utilization

Large-scale exploitation of fossil fuels and nuclear power can have an adverse effect on the human and natural environment. That need not be the case, if the effect on the environment is carefully assessed to ensure the development of a sustainable approach. This paper examines the process of environmental impact assessment (EIA) for coal from an international perspective. The concept of EIA is not new. A formalized process of EIA was introduced in the USA in 1970, and more recently similar legislation has been implemented in other countries. The member states of the European Community are required to adopt EIA regulations, as set out in Directive 85/337/EEC. Elsewhere, in Japan and Australia, there are requirements for EIA and a growing need for the process can be seen in developing countries. A comparison is made of the EIA process for coal in the international arena, and exemplary procedures are highlighted. Potential problems such as delays, modifications and additional costs are analysed, and the benefits of EIA, both to industry and environment, are discussed. A database of coal-related EIA would facilitate an exchange of information on the subject.     

The European Directive on environmental impact assessment: Implementation at last?

Summary The Commission of the European Communities' directive on environmental impact assessment (EIA) finally came into force in July 1988. The main provisions of the Directive are described, together with the objectives it is intended to achieve and the key areas where member state legislation will need to be effective if the principal requirements of the Directive are to be properly implemented. These include adequate coverage of projects, sufficient information in EIA studies, and effective consultation and public participation. Most European countries have some experience with EIA but, as illustrated by the UK Channel Fixed Link reports, the quality of the studies undertaken is very variable. Recommendations are made for improvements in practice through more effective diffusion of best practice, better provision and use of EIA guidance, more focused EIA research, more effective consultation and closer collaboration between the different parties involved in the EIA process, and both quantitative and qualitative improvements in EIA training. The results of a recent survey of European EIA training activity indicate growing interest, but further progress in improving the provision of EIA training is needed before the Directive can be effectively implemented.Drs Christopher Wood and Norman Lee have both been involved on various Environmental Impact Assessment (EIA) studies for the European Commission and have written widely on EIA and related topics. Both are Senior Lecturers at the University of Manchester and they are co-Directors of its EIA Centre. Christopher Wood teaches mainly in the Department of Town and County Planning, Norman Lee in the Department of Economics.     

Mainstreaming environmental impact assessment as a tool for environmental management in Ethiopia: Current challenges and directions for future improvements

The Environmental Impact Assessment (EIA) was first entered into force in the United States of America in 1969 through the National Environmental Policy Act. Since then, the EIA was implemented in many other countries. In Ethiopia, EIA was formally introduced in 2002 by Proclamation No. 299/2002 after the establishment of the Environmental Protection Authority (EPA) in 1995 and the formulation of the Environmental Policy of Ethiopia (EPE) in 1997. This study, which is based on a document review, interviews, and the application of a survey questionnaire, analyzes the procedures and practices of the Ethiopian EIA system, seeks to clarify fundamental information regarding the EIA system and characteristics of the key elements of EIA processes, and finally, offers suggestions that could improve EIA practices in the country. The overall result of this study shows that Ethiopia adopted EIA procedures that are similar to western models; however, despite approximately 15 years of experience, its implementation is still poor to the point that the use of EIA as an instrument of environmental management could be questioned. The challenges identified by this study include institutional, organizational, and professional capacity gaps, which, in turn, have resulted in constraints ranging from improper screening, scoping, and production of EIA reports to ineffective review, monitoring, and post‐project evaluation. Additional challenges to the system include poor governance and corruption, rapid economic growth, and the mushrooming of micro‐ and small‐scale enterprises that cause pollution and environmental degradation. This article also provides comprehensive suggestions to improve EIA practices in Ethiopia.     

New Criteria for Sustainable Water Quality Management1

Abstract: New criteria, pollutant load of unit area (PLUA), are developed for sustainable water quality management, which not only avoids degrading water quality but also considers the equity of development between different generations. A simulation‐optimization model is established to determine PLUA, in which uses the QUAL2E model to simulate pollutant transport and formulates a linear programming model to optimize the objective of maximal loads (carrying capacity). Two watersheds, the Touchen creek and the Keya creek, both in Taiwan, are taken as case studies. The PLUA criterion is applied to several existing projects which have passed environmental impact assessment (EIA). The results show that if the Hsinchu Science‐Based Industrial Park discharges wastewater to the Touchen creek, the total pollutant discharge of 85.6 kg/day exceeds the allocated load. Consequently, a waste reduction of at least 23.4% is required. Although these existing projects have passed EIA, most of them violate the criterion of PLUA and thus contribute to continued degradation of water quality. This study suggests developing PLUA as a part of the process of strategic environmental assessment (SEA) for watershed management plans and then applying it to EIA as a criterion for new project assessment. Furthermore, if carrying capacities of all pollutant discharges and resource uses can be translated into loads per unit of area, an integrated sustainable watershed management plan can be developed.     

Environment and industrialization in Puerto Rico: disenfranchising the people

This paper explores the effects of industrialization policy on environmental regulation in Puerto Rico, focusing on implementation of the Environmental Impact Statement (EIS) review process. Adopted in 1970, the EIS process has been transformed to pave the way for extensive use of a concise, alternative mechanism for analysing project environmental impacts, one with less opportunity for public input. This policy shift, virtually replacing the full‐scale EIS, occurred as a way to mediate the conflict between environmental policy and industrialization policy. Formal public participation in environmental decision‐making became the target of reform by the Puerto Rican Government because it perceived that public review was interfering with the location of industry.     

Visual impact assessment: A neglected component of environmental impact statements in Ireland?

This paper documents the results of an analysis of Visual Impact Assessments (VIA) within a sample of Environmental Impact Statements (EIS) in Ireland. The standard of VIA conducted within the environmental impact assessment (EIA) process for three categories of development; piggeries, quarries and urban developments between 1997 and 1999 are evaluated. The extent to which VIA have complied with the Irish Environmental Protection Agency (EPA) guidelines and disparities between the results for each development category are examined. The survey concluded that (i) the standard of VIA is less comprehensive than might be expected, and (ii) the use of visualization techniques for VIA could be substantially improved.
