Pollution crackdown: 88 per cent construction sites in Maharashtra receive 'stop-work' notice

NEW DELHI: In a sweeping crackdown on air pollution, the Maharashtra government has issued stop-work notices to more than 1,000 construction sites across Mumbai, with nearly 88 per cent of active projects facing action for violating environmental norms, Environment Minister Pankaja Munde informed the state legislative assembly on Tuesday.

Presenting data from October 2025 to January 2026 under the ongoing “clean air” initiative, Munde said 1,047 stop-work notices and 1,981 show-cause notices were served to errant sites as authorities tightened enforcement against dust and pollution violations.

Of the 2,224 active construction projects in the city, 1,952 — about 88 per cent — have installed low-cost air quality sensors, while the remaining faced strict penalties.




On January 16 alone, 678 projects were ordered to halt operations for failing to comply with mandatory sensor installation norms, underscoring the government’s push for technology-driven monitoring of pollution sources.

“We are following a strict escalation matrix for violators. Construction projects failing to adhere to dust-mitigation guidelines are first given a formal intimation, followed by a show-cause notice, and then a stop-work order if they remain non-compliant,” Munde said in a written reply on AQI levels.

The minister asserted that Mumbai’s air quality has largely remained within the ‘satisfactory’ (51–100) and ‘moderate’ (101–200) categories. Refuting allegations of a public health crisis, she cited reports from the Brihanmumbai Municipal Corporation (BMC) and Navi Mumbai Municipal Corporation (NMMC), which recorded no adverse health impacts among vulnerable groups such as children and senior citizens during the fluctuation in air quality.

As part of intensified enforcement, the BMC’s 25 ward-level flying squads have been targeting illegal debris transport, collecting over Rs 1.21 lakh in fines during the four months.

To tackle the city’s persistent dust problem, authorities have also deployed 126 water tankers and 25 misting machines, washing over 14,408 kilometres of roads.
