Here is the information about the 4SLB “new data” floor data from the Thunder Creek compressor site with the five controlled engines. These are located in two earlier RICE dockets. As far as I know, as of several days ago, this data has not yet appeared in the current rulemaking docket. It was not provided “after” the MACT proposal to EPA – it may have been re-discovered by EPA since the proposal.
