Senior Regulatory Specialist

The Closure and Interim Measures (C&IM) organization at H2C performs waste management area closure activities for the Hanford tank farms in accordance with Site-wide integrated closure strategies. The C&IM organization is in search of a Senior-level Regulatory Technical Specialist to support the strategic planning, performance, and reporting of technical evaluations associated with facility closure, interim measures, and correction actions for soil contamination, tank waste residuals, and contaminated equipment in tank farm areas.

The successful candidate will support baseline planning and implementation of vadose zone characterization and corrective actions, serving as a RCRA subject matter expert for tank closures. They will develop strategies for single-shell tank closure, lead and prepare technical and regulatory plans and reports in coordination with DOE and site contractors and ensure stakeholder acceptance. The role also includes providing technical oversight of subcontractor engineering work and preparing requisition documents such as technical specifications and scopes of work.
