**Summary:**
This notice, issued by the Central Pollution Control Board (CPCB) Air Laboratory on October 9, 2025, pertains to the certification of Continuous Emission Monitoring Systems (CEMS). It follows previous communications published on the CPCB website on September 3, 2025, and meetings held with manufacturers on August 20, August 31, and September 9, 2025. The notice informs all CEMS manufacturers that they must submit an application to CSIR-NPL for Air Pollution Monitoring Equipment Product Certification under the CSIR-NPL India Certification Scheme (NPLI CS) for their CEMS instruments/equipment. The deadline for application submission is September 15, 2025. Failure to comply may result in the derecognition of their CEMS for use with the CPCB's OCEMS portal. Inquiries may be directed to Aditya Sharma, Scientist 'E' at the CPCB Air Lab.
