Closure Regulatory Professional

The Closure & Interim Measures (C&IM) organization performs the regulatory and technical work necessary to achieve tank farm closure. We develop the regulatory documents that support RCRA closure and corrective action, DOE Order 435.1 performance assessments, Tri Party Agreement milestones, and interim measures that protect the environment from past tank releases. Our work includes soil and groundwater contamination assessments, vadose zone characterization, development of Closure Plans and RFI/CMS documents, barrier projects, and coordination with DOE and regulatory agencies.

We are expanding our team and seeking an early to mid career Closure Regulatory Professional who is eager to grow into a regulatory subject-matter role while supporting major closure and corrective-action deliverables.

You will work at the forefront of one of the nation s most important environmental cleanup missions as part of a supportive team of scientists, engineers, and regulatory specialists. You will gain hands-on experience with regulatory processes central to site closure and contribute directly to protecting the environment and advancing long-term cleanup solutions.

The successful candidate will support C&IM regulatory strategy and document development efforts that guide tank farm closure. This role is ideal for someone who understands environmental data and regulatory frameworks and wants to develop deeper expertise in RCRA corrective action and site closure.

• Support preparation and revision of regulatory documents, including RCRA Facility Investigation (RFI) reports, Corrective Measures Studies (CMS), Sampling and Analysis Plans (SAPs), Data Quality Objectives (DQOs), Data Usability Assessments (DUAs), and Tier 2/3 Closure Plans.
• Assist in regulatory strategy development, helping interpret closure requirements, track milestone commitments, and coordinate responses to regulator comments.
• Review scientific and environmental data (prepared by modelers, geologists, engineers, and analysts) to ensure regulatory documents accurately reflect technical conclusions.
• Support coordination with DOE, Ecology, EPA, contractors, and stakeholders, by participating in discussions, preparing materials, and capturing meeting minutes, action items, and comment resolutions.
• Contribute to planning and execution of closure-related tasks, such as updates to RFI/CMS Work Plans, barrier and interim-measure documentation, and regulatory correspondence packages.
• Participate in internal review cycles, integrating technical inputs, incorporating comments, and preparing documents for formal transmittal.
• Support field-facing activities, such as reviewing sampling plans, understanding subsurface characterization efforts, and ensuring work aligns with regulatory commitments.
• Prepare clear, well structured presentations and summaries to communicate regulatory positions, document status, or technical concepts.

Grade 17:

• Bachelor s degree (BS) in Environmental Science, Geology, Hydrogeology, Environmental Engineering, Chemistry, Environmental Policy, or a closely related technical field and four (4) years related experience supporting environmental compliance, cleanup, site restoration, or regulatory documentation.

Grade 18:

• Bachelor s degree (BS) in Environmental Science, Geology, Hydrogeology, Environmental Engineering, Chemistry, Environmental Policy, or a closely related technical field and six (6) years directly related experience supporting environmental compliance, cleanup, site restoration, or regulatory documentation.
• Note the essential duties for this grade level are like that of the previous grade level; however the scope of responsibility is larger, and the expected level of performance is increased.

Grade 19:

• Bachelor s degree (BS) in Environmental Science, Geology, Hydrogeology, Environmental Engineering, Chemistry, Environmental Policy, or a closely related technical field and eight (8) years related experience supporting environmental compliance, cleanup, site restoration, or regulatory documentation.
• Note the essential duties for this grade level are like that of the previous grade level; however the scope of responsibility is significantly larger, and the expected level of performance is greatly increased.

• Experience assisting and conducting meetings, briefings, preparing/delivering technical presentations, and documenting technical meeting notes and actions.
• Ability to interpret environmental and scientific data (e.g., geologic, hydrologic, analytical) and accurately incorporate findings into regulatory documents.
• Proficiency with Microsoft Office applications (Word, Excel, PowerPoint, Outlook).
• Familiarity with RCRA corrective action, and/or state cleanup regulations (e.g., MTCA); knowledge of Hanford Site regulatory frameworks or the Tri-Party Agreement is a plus.
• Experience with preparation of regulatory documents such as Work Plans, SAPs, DQOs, Corrective Measures Studies, or Closure…
