We will be covering the important questions and topics for competitive examinations for 2017 related to environment, biodiversity, ecosystem and related policies. As per video tutorials and lectures at Youtube@Examrace

Expected Questions on Environment and Biodiversity Part 1

Dr. Manishika Jain in this video covers a variety of topics which are important for 2017. These include the expected questions on environment and biodiversity.

Four-colour Classification Scheme

Based on Pollution Index (PI)

It is a function of:

  • Emissions
  • Effluents
  • Hazardous wastes generated and
  • Consumption of resources

Red category:

  • PI score of 60 and above
  • These are severe polluting industries with 60 industries including sugar, thermal power plants, paints

Orange category:

  • PI score of 41 to 59
  • They are moderately polluting industries with 83 industries like coal, washeries and automobile servicing

Green category:

  • PI score of 21 to 40.
  • They are significantly low polluting industries with 63 industries

White category:

  • PI score below and upto 20
  • They are non-polluting industries with 30 industries
  • These industries are exempted from requirement of environmental clearance

New Standards for Genesets

MoEFCC Gensets running on Liquid Petroleum Gas (LPG) / Natural Gas (NG), Diesel with LPG/NG and Petrol with LPG/NG.

Aim: To control air and noise pollution emanating from the operation of Gensets

Standards for Gensets:

  • Running on LPG/NG, or in combination with diesel/petrol have been notified for the first time.
  • In all, the three fuel modes of operation a three-tier classification has been adopted
  • Control the air and noise emission profile across different category of Gensets and would be revisited in 4 - 5 years once air and noise emission quality data and technological details pertaining to Gensets are available.
  • Standards have mandated in terms of ‘Type approval’ and ‘Conformity of Production’
  • Certification for engine products by empanelled agencies which will help in regulating the unorganized sector
  • Curb illegal import of Gensets in the country, which were observed to have higher air and noise emission values.
  • Improved environmental standards for Thermal Power Plants (TPPs) and Common Effluent Treatment Plants and Sugar Industries (CETPs).
