Discussion

NAIMA supports the carbonyl sulfide, PM, and binder HAP limits, as well
as, the 3 year compliance period, the sub-categorization of sources, and
the SSM requirements. NAIMA expressed concern with the limits for
horizontal curing and collection; EPA replied that the limits for
horizontal collection support the data that was submitted and that EPA
is reviewing the supplemental data form Rock Wool but may need
additional information (i.e., scrubber parameters) to move forward.
Industry also discussed concerns with HF and HCl limits and the fact
that there is such little test data. EPA stated they would consider any
additional test data if submitted within a timely manner.  EPA concluded
the meeting by explaining the SSM requirements in the supplemental
proposal.
