As per the Solid Waste Management Rules, 2016 in India, which one of the following statements is correct?

  1. A.Waste generator has to segregate waste into five categories.
  2. B.The Rules are applicable to notified urban local bodies, notified towns and all industrial townships only.
  3. C.The Rules provide for exact and elaborate criteria for the identification of sites for landfills and waste processing facilities.
  4. D.It is mandatory on the part of waste generator that the waste generated in one district cannot be moved to another district.

Correct answer

C. The Rules provide for exact and elaborate criteria for the identification of sites for landfills and waste processing facilities.

Explanation

The correct answer is C. The 2016 Rules set out detailed criteria for choosing sites for landfills and waste processing facilities.

The Solid Waste Management Rules, 2016, framed under the Environment (Protection) Act, 1986, replaced the Municipal Solid Wastes Rules of 2000. They require every waste generator to segregate waste into three streams: biodegradable or wet waste, non-biodegradable or dry waste, and domestic hazardous waste. Their reach goes well beyond municipal areas, covering urban agglomerations, census towns, notified industrial townships, areas under Indian Railways, airports, ports, special economic zones, defence establishments and places of pilgrimage. A schedule to the Rules lays down how a landfill site is to be chosen, such as its distance from rivers, habitations, highways and airports, along with standards for processing plants.

A is wrong because segregation is into three categories, not five. B is wrong because the Rules cover many more areas than those listed. D is wrong because the Rules place no such ban on moving waste across districts.

Exam tip: SWM Rules 2016: three-way segregation, wet, dry and domestic hazardous.
