Overview of the Regulatory Baseline, Technical Basis, and Alternative Control Levels for Sulfur Dioxide (SO2) Emission Standards for Small Steam Generating Units

摘要

The report provides a summary of the technical data used in developing proposed new source performance standards (NSPS) for small industrial-commercial-institutional steam generating units (small boilers). The report focuses on sulfur dioxide (SO2) emissions from boilers firing coal and oil with heat input capacities of 100 million Btu/hour or less. Conclusions are drawn from the data regarding the performance of technologies available to reduce SO2 emissions. Alternative control levels are then chosen based on the conclusions drawn from the data.
