New Delhi, Jan 7: The staff operating the smog tower at Connaught Place here shut it down on Sunday over alleged non-payment of their salaries, according to sources.

However, an official of the Delhi government said that the Delhi Pollution Control Committee (DPCC) in December sanctioned funds to the project management consultant, NBCC (India) Limited, for the payment of salaries to the staff of Tata Projects Limited (TPL), who operate the smog tower.

"The staff of Tata Projects Limited raised concerns about delayed salary payments, and the Delhi government cleared the dues in December. The NBCC, responsible for disbursing funds to Tata Projects Limited, failed to do so due to non-submission of utilisation certificates," the source said.

Sources said the DPCC will hold a meeting with the NBCC and TPL regarding the issue on Wednesday.

In 2021, two smog towers were installed in Delhi - one at Connaught Place under the DPCC and another at Anand Vihar under the Central Pollution Control Board (CPCB) - following directives from the Supreme Court.

The smog tower at Connaught Place was temporarily shut down based on unilateral directions from the chairman of the DPCC, Delhi Environment Minister Gopal Rai had claimed earlier. It was restarted in November following orders from the apex court.

According to the CPCB data, during the 2021-22 winter season, the smog tower at Anand Vihar reduced PM2.5 concentration by up to 17 per cent and PM10 levels by up to 27 per cent within a 100-metre radius.

Last year, the Delhi government said that the Connaught Place smog tower could decrease air pollution by 70 to 80 per cent within a 50-metre radius and by 15 to 20 per cent up to 300-metre radius.

In November, the DPCC informed the National Green Tribunal (NGT) that the two experimental smog towers in the city were ineffective in reducing air pollution. The operation of these costly giant air purifiers lacks merit, according to a report submitted to the NGT by the pollution control body.

Nadita Moitra, a senior scientist at the DPCC, said in the report that the Rs 25-crore smog tower at Connaught Place, operational for two years, can only mitigate air pollution by up to 17 per cent within a 100-metre radius.

Considering Delhi's vast area of 1,483 square kilometres, the pollution control body highlighted the need for more than 47,000 such towers, each costing Rs 25 crore for installation and requiring Rs 15 lakh monthly for operation and maintenance.

The DPCC report argued that achieving a mere 17 per cent reduction within a 100-metre radius, with a one-time cost of Rs 25 crore and a recurring cost of Rs 10 to 15 lakh per month is "not at all justified. It is not even a drop in the ocean".

It concluded that both towers were experimental, and their results did not warrant the heavy expenditure.

Chennai: Journalist and political commentator Sujit Nair has expressed concern over speculation that the Dravida Munnetra Kazhagam and the All India Anna Dravida Munnetra Kazhagam could explore a post-poll understanding to prevent Vijay-led Tamilaga Vettri Kazhagam from forming the government in Tamil Nadu.

In a social media post, Sujit Nair said the election verdict in Tamil Nadu reflected a clear public demand for political change and argued that the mandate should be respected irrespective of political preferences.

Referring to reports and political discussions surrounding a possible understanding between the DMK and AIADMK, he said he hoped such developments remained only speculative conversations and did not turn into reality.

Nair stated that if such an alliance were to take shape, it would raise serious questions about ideological politics in the country. He said TVK had emerged through a democratic electoral process and that the legitimacy to govern in a parliamentary democracy comes from the people’s verdict.

According to him, attempts to prevent an electoral winner from forming the government through unexpected political arrangements may be constitutionally valid, but many people could view them as politically opportunistic.

He further said that such a move could particularly affect the political image of the DMK, which has historically projected itself around ideology, social justice and opposition politics. Nair said that in ideological terms, the DMK appeared closer to TVK than to the AIADMK, and joining hands with its long-time political rival only to remain in power could weaken its broader political narrative.

He added that the same questions would apply to the AIADMK as well, as the party had spent decades positioning itself against the DMK and such an arrangement could create discomfort among its cadre and supporters.

Drawing a comparison with Maharashtra politics in 2019, Nair said he had expressed similar views when the Shiv Sena formed an alliance with the Indian National Congress and the Nationalist Congress Party after the Assembly elections.

He said post-poll alliances between long-standing political rivals often create a public perception that ideology and electoral mandates become secondary when political power equations come into play.

Nair also said such developments increase public cynicism towards politics and reinforce the belief among voters that ideology is often sidelined after elections.

He maintained that the Tamil Nadu verdict was emphatic and said respecting both the spirit and substance of the mandate was important for the credibility of democratic politics.
