The operations at Rajya Sabha MP Rajinder Gupta-owned Trident Group’s sprawling Dhaula industrial complex in Barnala district have come under a cloud as the firm has reportedly stopped accepting new export orders and begun offering transfers to some employees amid ongoing proceedings by the Punjab Pollution Control Board (PPCB).The development follows a major PPCB raid conducted at the unit in April this year. Sources said the board had since issued multiple notices to the company and directed its management to submit its reply at its headquarters on June 30. In April, Gupta was among seven Aam Aadmi Party (AAP) MPs who switched over to the Bharatiya Janata Party (BJP).Gupta also held a nearly two-hour meeting with the Deputy Commissioner (DC) and Senior Superintendent of Police (SSP) in Barnala on Tuesday, though details of the discussions were not available.The Dhaula complex on Mansa Road, spread over nearly 700 acres, houses multiple units, including towel, paper, textile, spinning, chemical and power-generation facilities. It is considered one of the largest industrial units in the region, with a large number of families dependent on it directly or indirectly.“The company has been asked to appear in person and submit its reply by June 30. We will present our position before the authorities, but preparing for the worst. New recruitment has been halted and no fresh export orders are being accepted at present. Some employees have also been offered transfers to the manufacturing plant in Budhni, Madhya Pradesh,” said a senior executive.Following the raid in April, the company moved the Punjab and Haryana High Court against the state government, alleging political vendetta.
