New Delhi, Feb 21 (NationPress) In a significant step towards enhancing industrial emission controls throughout the National Capital Region (NCR), the Commission for Air Quality Management in NCR and Adjoining Areas (CAQM) has issued a statutory direction proposing a stricter Particulate Matter (PM) emission limit of 50 mg/Nm³ for specific industries across Delhi-NCR.

Industrial emissions are a major contributor to elevated PM levels in Delhi-NCR, leading to the formation of secondary particulates that detrimentally affect air quality.

Recognizing the pressing need for enhanced regulations, the Commission has initiated a range of focused measures since its establishment.

These initiatives include mandatory shifts to cleaner fuels, setting emission standards for biomass and fuel-based boilers and furnaces, and publishing approved fuel lists through several statutory directives.

After evaluating recommendations from the Central Pollution Control Board (CPCB), informed by a study from IIT Kanpur and insights from a CPCB Technical Committee, the Commission has determined that a PM emission threshold of 50 mg/Nm³ is not only technically feasible but also crucial for environmental health.

This updated standard is anticipated to significantly cut down industrial emissions, aiding in the reduction of air pollution and enhancing overall air quality in the region. It will also benefit communities residing near industrial zones.

As outlined in the press release, the maximum allowable PM emissions from 17 categories of highly polluting industries identified by CPCB—including Red Category (medium and large) air-polluting industries, food processing units, textile operations utilizing boilers or thermic fluid heaters, and metal industries operating furnaces in Delhi-NCR—will now be 50 mg/Nm³.

It’s important to note that this standard will not apply to industrial units already assigned a PM emission standard lower than 50 mg/Nm³ under any existing consent, directive, or statutory provision.

The new PM emission regulations will take effect for large and medium industries starting August 1, with the remaining industries following on October 1.

Furthermore, the CAQM has instructed the respective NCR State Governments, GNCTD, and Pollution Control Boards in Haryana, Uttar Pradesh, and Rajasthan, as well as the Delhi Pollution Control Committee, to ensure the effective enforcement of these statutory directions, especially regarding compliance timelines for the revised PM emission standards, and to conduct extensive IEC activities to educate stakeholders and raise awareness.
