The petition, drawn and filed by advocate Gaurav Kumar Bansal, said an assessment by the Central Pollution Control Board (CPCB) found that the ambient air quality in Delhi during the 2016 odd-even scheme had deteriorated.
The oversight committee, headed by former judge Justice U C Dhyani, told the NGT that there was some delay in the proceedings relating to the eviction of encroachers because of the Model Code of Conduct during the elections.
A bench headed by NGT Chairperson Justice Adarsh Kumar Goel said the NGT has no objection to any legitimate project which does not interfere with the rejuvenation of Yamuna and protection of its flood plains.
"The NGT may consider reprimanding the officers of HPCB for their inability to discharge their statutory functions and lack of any regulatory vigil or control over industrial pollution and other activities like sand mining and construction of bunds on the Yamuna," NGT said.
The order came while perusing a report dated July 12 which informed it that forestry staff strength has been increased from 108 to 398 while ministerial staff strength has been increased from 22 to 36 and there is also increase in the infrastructure.
