author and implementation, 4) student intern and contract associate supervisor and manager, 5)
local and national liaison for SNL and its mission, 6) data collection, reduction and analyses, and
7) SNL-SAND and SBA final reports author and distributor. Pertinent action items include
creating, implementing and maintaining: a) Statement of Work documents (SOWs), b) Standard
Operating Procedures (SOPs), c) Specific Procedures (SPs) for laboratory equipment use, d)
Environmental Safety and Hazards (ES&H) NEPA and PHS screenings and records, e) yearly
budgets (6 years) for two SBA studies as the PI, f) Features, Events and Processes (FEPs)
records for WIPP Repository recertification, and g) implementation of appropriate laboratory
experiments and data analysis, Quality Assurance (QA) procedures and documentation.
