CPCB's Latest Directive for NCR-Delhi Industries: Mandatory OCEMS & PTZ Camera Installation by December 31, 2025
Critical Deadline Alert: Industries Face Closure Risk for Non-Compliance
The Central Pollution Control Board (CPCB) has issued a stringent directive mandating all air-polluting industries in the National Capital Region (NCR) and Delhi to install Online Continuous Emission Monitoring Systems (OCEMS) and Pan-Tilt-Zoom (PTZ) cameras by December 31, 2025. With just weeks remaining until the deadline, over 2,254 highly polluting industrial units still haven't complied with these requirements.
Union Environment Minister Bhupender Yadav has made it clear that strict action, including immediate closure, will be taken against industries that fail to meet this deadline.
Understanding the CPCB Directive: What You Need to Know
Who Is Affected by This Mandate?
The CPCB directive specifically targets:
Priority Industries in NCR-Delhi:
- Textile manufacturing units
- Food and food processing industries
- Metal industries and foundries
- All medium and large-scale red-category industries
- Any industrial unit operating boilers, furnaces, or emission-generating equipment
The mandate applies to industries operating across Delhi and NCR districts in four states: Delhi, Haryana, Uttar Pradesh, and Rajasthan.
What Are OCEMS and Why Are They Mandatory?
Online Continuous Emission Monitoring Systems (OCEMS) are advanced automated systems that continuously monitor and transmit real-time emission data directly to CPCB servers. These systems track critical pollution parameters including:
- Particulate Matter (PM) - Fine particles released into the air
- Sulfur Dioxide (SO2) - Harmful gas from fuel combustion
- Nitrogen Oxides (NOx) - Pollutants from high-temperature processes
- Other industrial emissions - Based on industry type and fuel used
The implementation of OCEMS represents a major shift from periodic manual monitoring to continuous, transparent real-time data reporting, eliminating opportunities for data manipulation or delayed corrective action.
PTZ Camera Installation Requirements
Technical Specifications for PTZ Cameras
Industries must install industrial-grade IP cameras with the following specifications:
Mandatory Features:
- Pan, Tilt, and Zoom (PTZ) functionality with 5x or above focal length
- Day and night vision capability for 24/7 monitoring
- Minimum resolution of 352 x 240 pixels or higher
- Real-time data streaming via leased line connection
- Direct connectivity to CPCB servers
Installation Guidelines:
- Cameras must focus on monitoring stations, stack outlets, and emission points
- For Zero Liquid Discharge (ZLD) units, cameras must monitor effluent channels
- Sensors and sampling points must be clearly visible in camera footage
- DVR/NVR backup for one-month data retention is mandatory
- Continuous operation without interruption
The PTZ cameras serve as a visual verification tool, allowing regulators to remotely monitor industrial operations and confirm that emission control equipment is functioning properly.
CSIR-NPL Certification Requirement
Critical Update: Only Certified OCEMS Will Be Accepted
Following directives issued on October 1 and October 9, 2025, the CPCB has mandated that only CSIR-NPL (Council of Scientific and Industrial Research - National Physical Laboratory) certified OCEMS can be connected to CPCB servers.
Key Points About Certification:
- 21 OCEMS models have been certified by CSIR-NPL for various parameters
- The certified models list is updated regularly on the CPCB website
- Industries must verify their equipment is NPL-certified before installation
- Non-certified systems will be rejected for connectivity
This certification ensures standardization, accuracy, and reliability of emission data across all monitoring stations nationwide.

- Invest in dedicated IT personnel for system management
- Utilize cloud-based platforms for data management
- Conduct thorough staff training on system operation
Challenge 3: Multi-Location Coordination
Companies with facilities across different NCR states must coordinate compliance across SPCBs with varying digital maturity.
Solution:
- Designate a central compliance team to oversee all locations
- Standardize equipment and procedures across facilities
- Maintain regular communication with all relevant SPCBs
- Create a unified reporting and documentation system
Challenge 4: Capital Allocation
The investment required for OCEMS, PTZ cameras, connectivity infrastructure, and calibration equipment can be substantial.
Solution:
- Explore government subsidies and environmental financing options
- Consider the long-term operational savings from improved efficiency
- Factor in the cost of non-compliance (closure and penalties)
- Investigate leasing options for monitoring equipment
Data Transparency and Dashboard Access
The New Era of Real-Time Monitoring
One of the most significant aspects of this directive is the level of transparency it introduces. All emission data is now accessible to regulators through centralized dashboards, providing:
Real-Time Visibility:
- Instant access to current emission levels
- Historical trend analysis
- Automated exceedance notifications
- Comparative analytics across industries
Public Accountability:
- Emission data may be made available for public scrutiny
- Enhanced corporate accountability for environmental performance
- Pressure to maintain compliance at all times
Reduced Margin for Error:
- No opportunity for delayed reporting or data manipulation
- Instant flagging of deviations from permissible limits
- Immediate regulatory intervention when necessary
This transparency leaves no room for corrective delays or retrospective data adjustment, making continuous compliance essential rather than periodic.

Conclusion: Act Now to Avoid Closure
The December 31, 2025 deadline for OCEMS and PTZ camera installation is non-negotiable. With the Union Environment Minister personally overseeing compliance and over 2,000 industries still non-compliant, the risk of closure is very real.
Industries must treat this as an urgent priority, not just a regulatory checkbox. The shift to real-time, transparent emission monitoring is here to stay, and early adopters will gain significant competitive advantages.
Immediate Action Steps:
- Review your current compliance status today
- Contact certified vendors immediately if not yet compliant
- Prioritize installation at critical emission points
- Ensure full connectivity and data transmission before December 31
- Document all compliance activities thoroughly
The cost of compliance is far less than the cost of closure. Protect your business, demonstrate environmental responsibility, and embrace the future of industrial operations in India.
