These standards were recommended by the Central Pollution Control Board (CPCB) after consultations with industries and other stakeholders.
The 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, according to the ministry.
These standards will 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.
These standards have mandated certification for gensets in terms of ‘Type approval’ and ‘Conformity of Production’ for air emission as well as noise emission.
The manufacturers are required to obtain the certification for engine products by empanelled agencies, which will help in regulating the unorganised sector thereby help in curbing the illegal import of gensets in the country, which were observed to have higher air and noise emission values, according to the ministry.
