1.8 EIA

EIA

2020-07-06 18:41:43


  • through EIA planners try to harmonise dev activities w/ environmental concerns
  • can prevent future liabilities or expensive alteration in project design
  • objective is to foresee potential env problems, identify key impacts issues
  • started in 1976-77 for river valley projects

EIA in India

Screening

  • to see whether a project requires env clearance
  • based on criteria like scales on investment, type of dev, location of dev

Scoping

  • process of detailing the terms of reference of EIA
  • done by a consultant, MoEFCC has published sector-wise guidelines
  • Quantifiable impacts are assessed and non quantifiable impacts such as aesthetic value determined

Baseline Data

  • describes existing environmental status
  • primary data should be monitored and supplemented by secondary ones

Impact Prediction

  • way to map env consequences, predict all factors and uncertainities that would arise
  • Impact on air, noise, water, land, biological, socio economic and impact on economic status

Assessment of Alternatives, Delineation of Mitigation Measures and EIA Report

  • for every project possible alternative be identified and env attributes of it compared to the original project
  • should also consider the no project options, alternatives should then be ranked
  • mitigation plant for the selected option supplemented with an Env Management Plan : to manage clearance conditions
  • EIA report should provide info on various env scenarios w/ and w/o the project

Public Hearing

  • public be informed and consulted after completion of EIA report
  • consisting of bonafide local residents, local associations, env groups etc

Environment Management Plan

  • should include delineation of mitigation and compensation measures, unmitigated impacts
  • physical planning, time schedule, location etc for mitigation and compensation sys in place
  • Delineation of mitigation plan

Decision Making

  • consultation b/w project proponenets and EIA authority
  • decision on env clearance

Monitoring Clearance Conditions

  • during both construction and operation phases of a project
  • to ensure commitments are complied and to observe prediction of EIA were correct or not
  • corrective action when there is deviation from prediction

Components of EIA

  • Rapid EIA differs from comprehensive in terms of time scale, done to show if a comprehensive EIA is req or not

Air Env

  • determinatinon of impact zone, monitor existing status of ambient air quality
  • monitor site specific meteorological data, estimate quantities of air emission
  • predict changes in it

Noise Env

  • monitor present levels and predict future noise levels
  • identify imapct due to it, recom mitigation measures

Water Env

  • study of existing ground and surface water resources wrt quantity and quality
  • predict impact, quantify and characterisation of waste
  • evaluate proposed pollution prevention, predict impact of effluent discharge, assess feasibility of water recycling

Biological Env

  • assess flora and fauna, potential damage to both terrestrial and marine flora and fauna
  • predict biological stress within impact zone, delineate mitigation measure to prevent/ reduce damage

Land Env

  • studies on soil characterstics, estimate on impact of project on land use, landscape topography
  • identification on potential utility of treated effluent, estimation and characterisation of solid wastes

Socio-economic and Health Env

  • collection of demographic, epidemiological data, projection of anticipated changes in socio-economic and health
  • assess impact on historical and cultural and archaeologica sites
  • assess rehab requirement w/ special emphasis on scheduled areas

Risk Assessment

  • Hazard identification, Maximum Credible Accident MCA to id potential hazardous scenarios
  • Analysis of possible failures and accidents resulting in fires
  • Hazard and Operability HAZOP studies
  • Assessment of risk, preparation of o site and off site DM plan

Environment Management Plant

  • Delineation of mitigation measures, monitoring scheme for compliance
  • Delineate implementation plan viz scheduling and resource allocation

EIA Notification of 2006 #important #Act

  • It has decentralised the env cliearance projects by classifying them into Categories A and B
  • 'Category A' projects are appraised at national level by Impact Assessment Agency (IAA) and the Expert Appraisal Committee (EAC).
  • Category B projects are apprised at state level by State Level Environment Impact Assessment Authority (SEIAA) and State Level Expert Appraisal Committee (SEAC).
  • Category A projects require mandatory environmental clearance and thus do not undergo the Screening process
  • Category B projects undergoes screening process and they are classified into two types B1 and B2.
  • B1 requires mandatory environmental clearance. B2 do not require EIA.

Key Element of Initial Project Description and Scoping

  • for key projects, Initial Project Description IPD to enable project screening and scoping -> this would facilitate reviewers task
  • IPD should provide - location and land use, details of project, outlining key element of project, offsite and onsite activities

Siting/ Project Location Critera per MoEF

  • prime agricultural land/forest land may not be converted to industrial site
  • land acquired be min, space for storing solid waste, layout should conform to landscape of CRZ norms] should be followed
  • project location be reviewed for ambient air, critically polluted ares, natural disaster prone areas etc

Procedure for Public Hearing

  • coys that want public hearing for clearance of projects should submit to SPCB #important
  • SPCB gives notice to be published in 2 newspapers along mentioning the date, time and place of public hearing
  • suggestions from public within 30 days from date of publication of notification, can also make oral/ written suggestion
  • Public hearing panel could have rep of SPCB, DC, rep of State gov, max 3 reps from local bodies viz Municipalities, panchayats etc

Drawbacks of EIA in India

  • several projects not listed because they are not listed in Schedule 1 or do not have high enough investmemt
  • teams formed for conducting EIA lacks expertise, lack of exhaustive ecological and socio-economic indicators for IA
  • Public hearing not being taken at early stage, no of projects not included in mandatory public hearings, indigenous knowledge of people not respected during EIA
  • Reports mostly incomplete, ignore or omits significant info, many reports are base only on a single season
  • reports made for clearance, unbiased review is missing, bending of rules common
  • documents are bulky, technical, sometimes fraudulently made
  • No accredition of EIA consultants
  • EMP for strategic industires viz nuclear are kept confidential, details regarding effectivenes and implementation not provided, emergency preparedness plans not discussed

Recom

  • Independent, sector wide EIA needed, creation of info desk, creation of centralised baseline data bank
  • all projects where there is a significant alteration of ecosys should compulsorily go through env clearance, no industrial act in ecologically sensitive area
  • Public hearing for most projects
  • Focus shifts from utilisation of exploitation to conservation of ecosys
  • impact on agribiodiversity, and traditional knowledge should be included
  • clearly state adverse impact, studies should be carried for at least 1yr
  • State amd Centre should make list of credible and independent competent agencies along w/ national level accredition
  • prior informed consent of local communities be made mandatory, language for specifying condition be made clear and specific
  • executive committee be replace by expert comm
  • automatic withdrawal of clearance if condition of clearance not met, robust monitoring mechanism estd by state dept
  • Judicial upheaval of NGT
  • Capacity building

Environment Supplement Plan ESP

  • undertaken by an alleged violator of EIA 2006 act to get clearance for their project
  • can continue their activity by paying financial penalty

Negatives

  • attempt to legalise violations, defeats the purpose of EIA
  • indirectly allows pardoning of violations, escape mechanism for violators
