A bench headed by NGT chief Justice Swatanter Kumar asked the Central Pollution Control Board (CPCB), the Delhi Pollution Control Committee (DPCC) and a representative of the Ministry of Environment and Forests to conduct a joint inspection at the site and submit a report.
It also asked the team to apprise it whether NBCC has planted trees and created permanent barriers around its redevelopment project or not.
"We direct CPCB, DPCC and a representative of the Ministry of Environment and Forests to conduct a surprise inspection at the project of NBCC and report to the tribunal as to whether the directions contained in our order dated July 26, 2016 have been complied with in its entirety and are being effectively enforced at the site in question.
The directions came during hearing of a plea by south Delhi resident K S Gahunia who has alleged that NBCC, the project proponent, in the garb of redevelopment is destroying roads, "illegally" erecting barricades on the roads and causing air pollution.
NGT had earlier cracked the whip on NBCC for causing air pollution and environmental degradation while slapping an environment compensation of Rs 10 lakh on it.
