New Delhi, Nov 17: The National Green Tribunal (NGT) on Thursday ordered 10 builders in Faridabad district of Haryana to deposit bank guarantee of Rs 50 lakh each within three days for building faulty sewage treatment plants (STPs). If they fail to do so, their bank accounts would be attached. The NGT bench, headed by Justice Swatanter Kumar, also prohibited the builders from withdrawing money from their bank accounts and directed them to fix the STPs and get them inspected by the Haryana Pollution Control Board. The Tribunal also prohibited the builders from dumping sewage in the open. "Only after taking permission from the NGT would the accounts of the builders be de-freezed," Kumar said. The NGT bench was planning to impose an environment compensation of Rs 50 lakh each. However, the counsel for builders pleaded that they were facing mounting pressure of Non-Performing Assets and thus asked for reduction in the compensation.
