Revision 1: This Environmental Checklist (EC) revises EC 14-010 (Overarching [OA] 18), Accelerator Mass Spectroscope Purchase, Lab Remodel, Installation, and Operation. This work is part of the overall operation of the Accelerator Mass Spectrometer. The Project Description, Environmental Aspects, Work Activities, Conditions and Instructions in this revision are specific to this revision. The original EC remains fully valid for the work described therein. This continues work under the laboratory-directed research and development (LDRD) 14C Analyses by Accelerator Mass Spectrometry. This research involves the chemical techniques required to convert samples into graphite prior to analysis by mass spectrometry. The overall process steps vary according to the initial sample matrix and include digestions, leaching, heating in furnaces, gas phase transfers and cryogenic trapping in a gas manifold system. Activities are to be located in Research and Education Campus (REC)-603 lab A7 and REC-611 labs 101 and 102. This project is an LDRD that is currently funded for Fiscal Year (FY) 16 and FY17; research is intended to result in subsequent programmatic research activities that could continue for periods > 5 years from the current date. Project is funded at the $175K level for FY16.
