Ms. Dittmer tracked CHPRC’s project progress to document the completion of milestones. She supported project staff and DOE to ensure compliance with decision documents and milestone schedules, supporting negotiations between the client and the regulatory agencies. Ms. Dittmer’s interpersonal skills permitted her to negotiate agreements and provide project status to support TPA compliance, establish priorities, and maintain progress toward cleanup. She supported the 100K Area CERCLA Decision Documents and Integration for CHPRC, integrating activities between various organizations (Groundwater, Soil Remediation, and D4) to ensure compliance with CERCLA Decisions and TPA milestones. She interfaced with DOE and the regulators for mutually acceptable approaches to achieve TPA milestones and continue compliant cleanup activities.

Ms. Dittmer supported North Wind, Inc., managing the CERCLA and Waste Programs. She provided project management for Mission Support Alliance (MSA) to support the ORP response to an EPA NOV regarding deficiencies in the management of universal waste at the Hanford site. To address EPA concerns, she facilitated several multi-contractor workshops, including Hanford site Prime Contractors, ORP, RL, EPA and the Washington State Department of Ecology to achieve a mutually acceptable revision to the Centralized Consolidation/Recycling Center (CCRC) Management Plan.
