Three years after mandating a continuous pollution monitoring in major industries, the Central Pollution Control Board (CPCB) has released guidelines for implementing this.

The guidelines for a continuous emission monitoring system (CEMS) direct how suitable monitors will be selected, installed, operated and meet compliance requirement. CEMS intends to improve environment compliance enforcement system in India. Similar systems have been successful in Britain, Germany and USA and are being replicated by India and China.

“It will be an easy guide for industries who intend to install CEMS. A local certification programme or an understanding with European standards will help industry in pre-selection of quality certified products,” says Sankar Kannan from SICK India Private Limited, a CEMS manufacturer.

Since the new pollution monitoring system came into force in February 2014, industry nearly failed to follow them amid lack of guidance on enforcement. Investment worth billions by nearly 4,000 industries in the new monitoring system failed to show any significant improvement in pollution control and compliance, due to sub-standard devices, incorrect installations and poor operation. Credible data on emission was sparsely collected. CPCB’s guidelines will help to ensure course correction.

Achyut Mishra, Member Secretary of Madhya Pradesh Pollution Control Board (MPPCB) congratulates the CPCB saying, “MPPCB has initiated CEMS orientation programmes for its officials.” Mishra thanks non-profit Centre for Science and Environment (CSE) for pioneering in CEMS capacity building initiatives.

What the guidelines entail   

  • Basic characteristics for a correct CEMS device.
  • A list of available technologies for monitoring air pollution parameters, their merits and demerits, and the suitability for different industries
  • Guides for correct installation, operation, maintenance, and calibration of CEMS devices.
  • Quality assurance as per the US and Europe regulations. It recommends use of certified CEMS equipments but allows uncertified equipments if checked by notified agency during installation
  • An indigenous certification system must be developed. Until then, CEMS equipments must meet their claims during field testing as per Europe and USA standards.
  • Requirement for calibration and recalibration of gaseous and dust monitors.
  • Recommends tamperproof data collection and transfer directly to four locations—CPCB, SPCB, regional or division office of SPCB and industry.
  • Demands 85 per cent data capture rate on 30 minutes average basis. However, compliance check average is not specified, it instructs immediate corrective actions and reporting to the regulator in case of exceedance.
  • A three stage data validation system to maintain quality. The data handling system must be automatic, capable of data analysis, record events, generate response automatically and present data in prescribed formats.
  • Accountability of stakeholders: Manufacturer or supplier must supply suitable equipments, avail spare parts and two-way communication software for data transfer with diagnostics. Industries are responsible for adequate infrastructure for CEMS installation, credible data transfer and required to use CPCB empanelled laboratories for assessment of installation, calibration and data validation.

Implementation is key

Regulators must use the guidelines to assess the current status of implementation and draw a plan for course correction. But smart systems demand smart hands to operate, so skill building for all involved parties should be the next step to ensure implementation.

“The guidelines have come out well, but spirited implementation will be crucial for real success. Capacity building for enforcement is required, which is a big task,” says Prashant Kokil, the chief sustainability officer at Tata Power.

Experts voice the demand for nodal agency to test CEMS performance during installation. Laboratories must be authorised for verifying after installation, calibration and validation. CPCB needs to expedite this process without any further delay. Similarly, the indigenous certification system which has been on the table since the inception of CEMS without any  effort to materialise it.

 “The guidelines will be a great help in CEMS programme, however the certification system, lab empanelment and capacity building are also important factors that are required for better implementation,” adds Achyut Mishra.

Framing of the indigenous certification system, must be taken by the Ministry of Environment, Forest and Climate Change (MoEF&CC) as it requires the participation of multiple bodies. However, CPCB being an apex environmental regulatory agency, has important role to play—preparation of a strategic plan and get required support from the MoEF&CC for implementation. The enforcement of the CEMS guidelines will be affected if these requirements are not fulfilled.

  • Excellent piece of work by the author and authorities. As a common person who worries a bit on his surroundings understands that the out come from all these installations and guidelines should add value for policy makers and regulators, only when the gathered data will get analysed for its credibility to find out the root cause for exceeding emissions. The regulatory authorities have to contribute in a role of mentor and trainer for capacity building of the involved population to achieve the emission beyond compliance.

    • Thank you for encouraging words. At times, the regulators also need to be mentor and guide to the industry. Capacity building of all the stakeholders are must.

  • Nice review on CEMs guide lines & analysis underling future requirements for successfuly implementation of guidelines through capacity building involving stakeholder agencies ie MoEFCC/ CPCB, CSIR/ NPL, NEERI, NABL/ QCI, Environmental Laboratories etc

  • For controlling polluting industries it is a good initiative provided the industries follow it in earnest.

  • I would like to impress an observation I have made regarding underground water pollution by industries doing coal tar processes, what are conditions and criteria for such industries and. Ways to protect water contamination by phenolic odours.
