can access the real-time data, online, anywhere and anytime. The system provides a customised facility to carry out analysis, produce reports, generate alarms, and record calibration and maintenance events with history backup. The remote calibration system for gaseous CEMS (see Figure 4) is another key innovation that the CPCB or respective SPCBs can use when they observe repeated abnormal data from any industry that they monitor. Using this system, a regulator can randomly choose to remotely trigger a zero and span drift test and assess the response of gaseous CEMS systems installed in the plants, showing up any failings.
ICSC’s study finds that India’s real-time monitoring technology is a significant initiative toward achieving a better environmental governance system. However, in the absence of some fundamental infrastructure and practices, it remains underutilised. Also, data quality remains poor and not properly assessed in the absence of onsite inspection, regular checks, and actions against defaulters.
Some of the SPCBs, it must be said, do carry out due diligence to an extent, but it is not standard practice. ICSC’s analysis of India’s coal-based power sector makes this apparent.
The need for capacity building The Indian government needs to fast track the development of an indigenous certification system and a list of approved third-party laboratories for tests and checks. On-site inspection and regular checks, which are part of good practice internationally, can help to resolve present challenges in the system. Improvement in data quality will build the confidence needed to give real-time data legal status in compliance checks, which requires amendments to the Water (Prevention and Control of Pollution) Act, 1974, the Air (Prevention and Control of Pollution) Act, 1981,

and the Environmental Protection Act, 1986. Delays and negligence will make the problems persist and may prove costly and delay effective policies supportive of sustainable development. One essential element is training and capacity building for regulators, plant operators and other stakeholders – throughout the process. The UK and the USA have established official training schemes for manual and real-time monitoring and data handling. The training and certification scheme run by the UK Environment Agency (MCERTS) covers all areas of emission and effluent monitoring, for individuals and organisations. Similarly, the US Source Evaluation Society (SES) has established the voluntary Qualified Source Testing Individual (QSTI) and Qualified Source Testing Observer (QSTO) training and certification scheme. In India, no such systems are in place for real-time emissions monitoring. Up to now, some of the training in real-time monitoring carried out by the CPCB, SPCBs, and other organisations in India has been very basic, non-standardised and non-accredited, and insufficient. ICSC, under the US Department of State project mentioned earlier, is in the process

ICSCarbon.org. The upcoming training sessions will bring together experts from across India, the USA and Europe to impart knowledge about pollution control technologies, plant operation optimisation and CEMS implementation. The project aims to enable the Indian regulators, policymakers, and operators to deal with one of the critical environmental problems facing India – air pollution, especially from coal combustion in power plants and other industrial sources – through improving performance, helping to meet tighter environmental norms, improving environmental compliance, and providing a framework for effective decision and policymaking.
As far as coal plant compliance with new emission limits is concerned, the ICSC assessment finds that the delay experienced so far is avoidable since the pollution control technologies required are readily available. Compliance could help to achieve a more than 80% reduction in SO2
, NOx by 2030.
But stakeholders must be empowered with the necessary knowledge and skills and the Indian government must have the courage to take firm and appropriate action that will, within the next decade, result in improved environmental status, health benefits for the population, and demonstrably sustainable economic ambitions.
