PREFACE
This third edition to Continuous Emission Monitoring comes 20 years after the second edition was published. Over that period, more sources in more industries have been required to monitor a wider range of pollutants at ever‐decreasing emission levels. To meet the challenges of more stringent regulatory programs, both monitoring technology and the management systems necessary to maintain them have developed to the point where accurate and precise emissions data can be obtained at the lowest ranges specified by regulatory agencies. The evolution of monitoring regulation and the technology necessary to support it are based on programs initiated in the 1970s and 1980s. These programs were described in the first and second editions of Continuous Emission Monitoring, which have provided a foundation for those newly entering or those needing to gain perspective of the field. This third edition extends that foundation to later programs implemented in the 1990s and 2000s. In the 1990s, continuous emission monitoring (CEM) systems were applied to support the determination of emission “allowances,” in the U.S. acid rain cap and trade program. Later, in the 2000s, regulatory programs for NOx emissions, mercury, volatile and “air toxics,” semi‐volatile organic and inorganic compounds were instituted, leading to significant challenges for the monitoring community. This book focuses on continuous emission monitoring requirements promulgated in the United States, although monitoring rules developed in Canada and the European Union are addressed where appropriate.
Continuous emission monitoring involves the sum of activities associated with determining and reporting pollutant emissions from stationary sources. Coal‐ and oil‐fired power plants, municipal and hazardous waste incinerators, petroleum refineries, cement plants, Kraft pulp mills, and, now, many chemical process industries are required to monitor emissions on a continuous basis. The emissions data obtained provide a continuous record that can be used by environmental control agencies to support a variety of regulatory programs. First used to monitor the operation of air pollution control equipment, regulatory applications have extended in the United States to use CEM systems for determining the compliance of stationary sources with their emission limitations. For CEM data to be credible, one cannot rely only on instrumentation. The implementation of a plant‐level quality assurance program, based on routine quality control procedures, has been found essential for data credibility. As a result, CEM quality assurance and quality control have become integral to CEM regulation.
One of the purposes of this book is to provide an understanding of both the regulatory and technical issues that must be considered when making decisions about CEM systems. As regulatory applications are extended, CEM system data are being used increasingly for process control and optimization. Although the use of CEM systems for determining compliance with pollutant emission limits has been the driving force for their installation, the benefits of knowing what and how much of something is being emitted are becoming more widely recognized. Here, the adage that “if you can measure it, you can control it” has led to the acceptance of CEM systems by managers who understand that CEM systems can be used for more than just meeting environmental regulations – that a knowledge of emission rates can also be used to optimize plant operations.
