The primary purpose of the meeting was for EPA to hear the questions
from industry regarding the type of analysis that was used to arrive at
the proposed MACT floor limits. Industry’s goal was to be sure they
understood EPA approach in developing the proposed MACT floor limits.
EPA’s approach that was used to develop estimates of daily mercury
emissions was discussed as well as the statistical analysis for
determining the proposed emission limit. 

It was agreed that Dr. Mills and Mr. Ybanez would summarize their
understanding of the EPA approach based on these discussions and submit
them to EPA for review and verification (or for further clarification if
needed)..
