This will provide a practical overview of the regulatory and technical requirements that drive successful Continuous Emissions Monitoring System (CEMS) implementation and compliance. Participants will gain insight into key EPA performance specifications, testing methods, and regulatory expectations that influence CEMS design, operation, quality assurance/quality control, and data availability. We will also explore critical considerations for selecting and designing sampling systems, data acquisition and handling systems (DAHS), and reporting frameworks, as well as best practices for achieving successful Relative Accuracy Test Audits (RATAs). Throughout the presentations, industry lessons learned, common compliance challenges, and frequently asked questions will be incorporated to provide real-world perspective and actionable guidance. Whether you are new to CEMS or looking to strengthen an existing monitoring program, this series will provide practical tools and insights to help improve compliance, data quality, and system reliability.
