Status of Online Continuous Emission Monitoring
System (OCEMS) as on 08.02.2026
Posted On: 08 FEB 2026 8:53PM by PIB Delhi
As part of its sustained and coordinated efforts to abate air pollution from industrial activities in the Delhi-
NCR, the Commission for Air Quality Management in NCR and Adjoining Areas has constituted a
dedicated Online Continuous Emission Monitoring System (OCEMS) Cell to strengthen its monitoring
and compliance mechanism.
For the purpose of independent verification of the installation and operationalization of OCEMS, a
Standard Operating Procedure (SOP) outlining the roles and functions of the OCEMS Cell was circulated
to all concerned agencies in NCR on 09.10.2025. As part of the Commission’s regular efforts towards air
pollution mitigation in the region, the OCEMS Cell convened a review meeting on 05.02.2026.
As per the latest information, the Cell has verified OCEMS installations in 865 industries so far and has
made structured recommendations to the concerned State Pollution Control Boards (SPCBs)/Pollution
Control Committees (PCCs), including issuance of notices in 530 cases and carried out field verifications
in 122 cases.
Based on these recommendations, the concerned SPCBs/PCCs are undertaking appropriate regulatory and
enforcement action(s) in accordance with the prescribed guidelines by Central Pollution Control Board
(CPCB), including imposition of Environmental Compensation (EC), issuance of Show Cause Notices
(SCNs) and further field verifications, as deemed necessary.
As per the directions of CPCB dated 01.10.2025 and 09.10.2025 for installation of OCEMS in selected
industrial sectors, including 17 categories of industries, Red Category (large and medium), and Food,
Metal and Textile industries in the NCR, the total number of industries required to install OCEMS.
Industries that have not initiated any action in this regard are proposed to be issued closure directions by
the respective SPCBs/PCCs.
The status is as given below:
State OCEMS installation requirement Current status of OCEMS installation/
issuance of purchase orders (as on
08.02.2026)
NCT of Delhi 128 57
NCR under 907 905
HaryanaNCR under 255 145
Rajasthan
NCR under Uttar 648 320
Pradesh
This initiative targets the Commission’s focus on ensuring adherence to prescribed emission standards,
promoting the adoption of cleaner fuels and technology and addressing particulate and gaseous emissions
through improved oversight by the industrial units.
The Commission emphasized that Industrial Pollution contributes to Particulate Matter and emission
levels in the NCR and remains committed to strengthen monitoring, compliance and enforcement
mechanism across the sector for abatement of air pollution in the region.
