In a decisive move to combat deteriorating air quality, the Navi Mumbai Municipal Corporation (NMMC) has taken stringent action against construction sites flouting pollution norms. The civic body has halted work at 19 ongoing construction sites and issued notices to a total of 42 sites for non-compliance with environmental regulations.
Winter Woes and Regulatory Crackdown
Commissioner Kailas Shinde explained that air pollution in Navi Mumbai intensifies every winter. Factors like slow wind speed, lack of strong winds, and high humidity trap pollutants near the ground, leading to foggy conditions and poor air quality. The crackdown specifically targeted sites where the Air Quality Index (AQI) exceeded 200.
This enforcement follows the NMMC's earlier issuance of a mandatory Standard Operating Procedure (SOP) for pollution control at all construction projects. Key measures include:
- Compulsory installation of air quality monitoring devices.
- Implementation of specific dust and pollution mitigation steps.
So far, 30 construction sites have installed these devices, with work underway at the remaining locations.
Flying Squads and Penal Actions
To ensure the SOP is implemented on the ground, the NMMC formed special flying squads at the divisional level. These teams, comprising deputy engineers, sanitation officers, and town planning officials, conduct rigorous inspections.
As a result of their vigilance:
- Notices were issued to 32 construction sites for causing air pollution.
- Show-cause notices were served to 10 other sites.
- Stop-work orders were enforced at 19 sites.
- Penalty notices were slapped on 173 developers.
Alongside punitive measures, the corporation is undertaking proactive cleaning. Roads and footpaths are being scrubbed with machines and brushes, and treated water is being used for washing roads. Regular anti-smog spraying with treated water is also being conducted to settle dust particles.
Official Data vs. Third-Party Reports
The NMMC also addressed concerns around varying reports on air quality levels, particularly in areas like Sanpada. The civic body clarified that only data from official sources like the CPCB website and the SAMEER app should be considered authentic and reliable.
An official pointed out that many third-party reports rely on low-cost sensor models or satellite estimates which often show a much higher AQI than the official Continuous Ambient Air Quality Monitoring Stations (CAAQMS). These sensors may not follow the calibration and certification process mandated by the Central Pollution Control Board (CPCB).
Commissioner Shinde appealed to citizens to trust the official channels for accurate air quality information and to cooperate with the civic body's efforts. "We take necessary measures to ensure good air quality in the city and appealed to citizens to cooperate in this effort," said Shinde.
