To 3M's knowledge, data from the other two participating laboratories have not yet been generated. - We are notifying the EPA of these data to fulfill our TSCA 8(e) reporting obligations, and will provide a copy of the complete final report (compiling data from all three laboratories) once it is made publically available by the National Park Service. If desired, the EPA can request draft data from the National Park Service prior to our final report submission.
