Prevention of Significant Deterioration (PSD) Monitoring Plan: 200-MW Atmospheric Fluidized Bed Combustion (AFBC) Demonstration Plant

摘要

For PSD purposes, the demonstration plant will be a major source (emissions exceed 100 TPY) for sulfur dioxide (SO sub 2 ), nitrogen oxides (NO/sub x/), and particulates. In addition, it is presumed at this time, that the AFBC will also be a major source for carbon monoxide (CO) and nonmethane hydrocarbons (HC). The PSD permit application will provide sufficient information for a review, relative to the applicable NAAQS for all of the above pollutants, and for the review of increment availability for SO sub 2 and TSP. The PSD monitoring plan describes TVA's plans for monitoring in support of these reviews. The monitoring plan is based on the existing rules and regulations for the prevention of significant deterioration and on the existing applicable Ambient Monitoring Guidelines for PSD. TVA's monitoring plan for the AFBC includes new monitoring for NO/sub x/, CO, and O sub 3 ; modeling results for SO sub 2 and existing monitoring data for TSP. The modeling alternative was chosen for SO sub 2 because a major existing source in the area (the Shawnee Steam Plant) has been, and is, undergoing significant source configuration changes, including various changes between the use of short and tall stacks and shifts between high and low sulfur coal. TVA intends to use monitoring data from recently installed PSD monitoring stations to support the air quality review for NO/sub x/, CO, and HC. It is expected that the changing source configuration of the Shawnee Steam Plant during the monitoring period will not significantly affect the representativeness of these measurements. Moreover, modeling, in TVA's judgement, would not be an acceptable alternative for these pollutants because of significant uncertainties in the emissions inventories and because of uncertainties associated with the complexity of the modeling.
