Audit

We reviewed the process and controls for emissions data reporting. Our objective was to ensure that controls are prescribed and functioning to ensure accurate emissions data reporting. The Continuous Emissions Monitoring System (CEMS) is in place at TVA fossil plants and combustion turbine facilities to report data on opacity, SO2, NOx, CO2, and flow. Fossil Power Group has a process that "is intended to satisfy the regulatory requirements for a quality assurance program (QA Plan) for the Continuous Emission Monitoring Systems (CEMS) by providing a uniform process for the assurance of Acid Rain compliance at Fossil Power Group (FPG) facilities." The process authorizes quality control procedures which characterize specific CEMS activities required to maintain compliance with current CEMS regulations.In summary, we determined controls are prescribed and functioning which ensure the accuracy of emissions data reporting. Specifically, we determined that the CEMS data is being approved and certified at the plant and the TVA Designated Representative (DR) level prior to submission to the Environmental Protection Agency. In addition to controls prescribed by the process, Environmental Compliance and Technology Applications performed environmental program reviews which also evaluated compliance with controls and quality procedures related to CEMS reporting.
