| Contents Notes |
In concluding that it was essential to identify and quantify variability, EPA failed to consider data on management of mercury variability from operating facilities -- Variability is best addressed by tailoring the form of the standard to account for variability -- EPA attempted to quantify variability in short-term peak emissions, even though the essential question for compliance with EPA's proposed standards is variability in long-term average emissions -- Although EPA relied heavily on the chlorine content of coal in estimating mercury emissions, there is no evidence of a significant correlation between the chlorine content of a sample of coal and the ability to control mercury emissions when that sample is burned -- EPA's estimation of mercury emissions using equations based on coal chlorine content is invalid -- Because the equations based on coal chlorine did not have strong value in predicting mercury emissions, the EPA's distributions of emissions estimates based in part on those equations are questionable -- EPA's selection of 97.5th percentile values could potentially be helpful in projecting peak emissions, but substantially overstates expected the average annual emissions that are relevant to the standard EPA actually proposed -- By treating EPA's 97.5th percentile value estimates as "data," and then determining means and upper confidence interval limits of those "data," EPA further overstated mercury emissions from the best performing 12% -- Even though a bituminous-fired unit could become a subbituminous-fired unit with little or no modification, EPA set a substantially higher emission limit for subbituminous-fired units, encouraging fuel swithching that would bring substantially higher mercury emissions. |
