The Portland Cement Association (PCA) met with EPA and presented
information on a statistical analysis of the mercury emissions data
using the 30-day averages instead of the daily emission values. They
also discussed the use of PM compliance test data that has been
collected for all portland cement kilns. Handouts were provided
including a meeting agenda and tables illustrating the results of their
statistical analysis.  They are attached to these meeting notes.
