Environmental Impact Assessment EIA Overview Session Objectives Explain

Environmental Impact Assessment (EIA): Overview Session Objectives: • Explain what EIA is about • Discuss the EIA process

Agenda • • • EIA & its evolution EIA principles EIA process Benefits of EIA Discussions

What is EIA? US EPA National Environmental Policy Act (proclaimed in 1970) called for: • public statement of environmentally significant consequences of all federal actions • public input into project formulation • informed decision-making This process became known as EIA

Purposes of EIA • • modify and improve design ensure efficient resource use enhance social aspects identify measures for monitoring & managing impacts • inform decision-making • provide justification for a proposal

Various Aspects of Environmental Impacts • • type and nature magnitude extent timing • • duration uncertainty reversibility significance

Integration within EIA The process of EIA has moved towards the consideration of all effects arising from a proposal. These can include: • • biophysical social health economic • risk and uncertainty

Evolution of EIA • Early 1970 s - initial development • 1970 s to 1980 s - trend to integration • Mid to late 1980 s - cumulative effects and policy integration • Mid 1990 s - towards sustainability (SEAstrategic environmental assessment, biodiversity)

EIA Developments in the 1990 s: • • Major reforms to well established systems Implementation of EC Directive (1985) World Bank and other agencies introduce policies Convention on EIA in a Transboundary Context (1991) • Conventions on Climate Change and Biological Diversity

EIA-Three Core Values • Sustainability - the EIA process will result in environmental safeguards • Integrity - the EIA process will conform to agreed standards • Utility - the EIA process will provide balanced, credible information for decision-making Sadler, 1996

EIA - Eight Guiding Principles • Participation • Credibility • Transparency • Cost-effectiveness • Certainty • Flexibility • Accountability • Practicality Sadler, 1996

EIA Operating Principles I EIA should be applied: • to all development project activities likely to cause potentially significant adverse impacts or add to actual or potentially foreseeable cumulative effects • so that the scope of review is consistent with the nature of the • as a primary instrument for environmental management to ensure that impacts of development are minimized, avoided or rehabilitated • on the basis of well defined roles, rules and responsibilities for key actors • project or activity & commensurate with the likely issues & impacts

EIA Operating Principles II EIA should be undertaken: • throughout project cycle, beginning as early as possible in the concept design phase • with clear reference to the requirements for project authorization & follow-up, including impact management Sadler, 1996 • consistent with the application of 'best practicable' science & mitigation technology in accordance with established procedures & project-specific terms of reference, including agreed timelines • to provide meaningful public consultation with communities, groups & parties directly affected by, or with an interest in, the project and/or its environmental impacts

EIA Operating Principles III EIA should address, wherever necessary or appropriate: • All related & relevant factors, including social and health risks & impacts • Cumulative and long-term, large-scale effects • Design, locational and technological alternatives to the proposal being assessed • Sustainability considerations including resource productivity, assimilative capacity and biological diversity Sadler, 1996

EIA Operating Principles IV EIA should result in: • Accurate & appropriate info as to the nature, likely magnitude & significance of potential effects, risks & consequences of a proposed undertaking & its alternatives • Preparation of an impact statement or report that presents this info in a clear, understandable & relevant form for decision-making, including reference to qualifications, & confidence limits in the predictions made • Ongoing problem solving and conflict resolution to the extent possible during the application of the process Sadler, 1996

EIA Operating Principles V EIA should provide the basis for: • Environmentally sound decision-making in which terms & conditions are clearly specified and enforced • Design, planning and construction of acceptable development projects that meet environmental standards and resource management objectives • An appropriate follow-up process with requirements for monitoring, management, audit & evaluation that are based on the significance of potential effects, the uncertainty associated with prediction & mitigation, & the opportunity for making future improvements in project design or process application Sadler, 1996

The EIA Process • Screening • Reviewing • Scoping • Decision-making • Assessing • Monitoring & managing • Mitigating • Public involvement • Reporting

EIA Costs for Multipurpose Projects in Thailand

Delays are caused during EIA when: • EIA is commenced too late in the project cycle • TORs are poorly drafted • EIA is not managed to a schedule • EIA report is inadequate and needs to be upgraded • Lack of technical data

Benefits of EIA include: • • more environmentally sustainable design better compliance with standards savings in capital and operating costs reduced time and costs for approvals avoids later plant adaptations reduced health costs increased project acceptance

Ensuring Fairness in the EIA Process • register consultants' names and terms of reference • name consultants and their expertise in the EIA report • publish the terms of reference in the EIA report • make EIA reports available to the public • publish lists of screening and final decisions along with conditions for approval
