Waste Treatment and Immobilization Plant Risk Assessment permit modification
Feb. 24 – April 9, 2020
We're holding a 45-day public comment period which will address proposed modifications to the Hanford Dangerous Waste Permit for the treatment, storage, and disposal of dangerous waste at the Waste Treatment and Immobilization Plant (WTP), located in Part III, Operating Unit Group 10 (Permit). The permittees are U.S. Department of Energy Office of River Protection and Bechtel National, Inc. WTP is located on the Hanford Site in Southeastern Washington.
The Effluent Management Facility under construction on the Hanford Site, part of the Direct-Feed Low-Activity Waste configuration.
Proposed changes
The proposed changes incorporate the draft preliminary risk assessment and the risk assessment work plan for the Direct-Feed Low-Activity Waste (DFLAW) configuration.
The risk assessment work plan supplements two through five would also be updated for incorporation into the permit.
This permit modification will update and add new documents to the WTP portion of the permit to support the risk assessment for the DFLAW configuration. Updates to the documents in Appendix 6.2 of the WTP portion of the permit are necessary to ensure the DFLAW configuration has been adequately analyzed and reviewed through the risk assessment work plan.
This permit modification also provides the draft pre-demonstration test risk assessment for WTP for Ecology review, as required by Permit Condition III.10.C.11.b and Interim Compliance Schedule EMF-9 of the WTP portion of the permit.
The draft risk assessment work plan for DFLAW and the pre-demonstration test risk Assessment for WTP use the best available information, approved models, U.S. Environmental Protection Agency combustion risk assessment guidance, and conservative exposure scenarios and assumptions.

DFLAW operating permit modification
Feb. 10 – March 26, 2020
We're holding a 45-day public comment period which addresses proposed modifications to the Hanford Dangerous Waste Permit for the treatment, storage, and disposal of dangerous waste at the Waste Treatment and Immobilization Plant (WTP). The permittees are the U.S. Department of Energy, Office of River Protection and Bechtel National, Inc. WTP is located on the Hanford Site in Southeastern Washington.
Background
WTP will operate in two processing configurations. For near-term operations, WTP will operate in the Direct-Feed Low-Activity Waste (DFLAW) configuration requiring the following WTP facilities to become operational first to process low-activity waste from Hanford's tank farms: Analytical Laboratory, Low-Activity Waste (LAW) Vitrification Facility, and the Effluent Management Facility (EMF).
In the DFLAW configuration, tank waste is pretreated to remove cesium and solids before being sent as low-activity waste to the WTP LAW facility. With DFLAW, the pretreated waste will bypass WTP's Pretreatment Facility and be fed directly from the tank farms to the LAW facility.
The liquid effluents generated in the LAW facility and the Analytical Laboratory are transferred and treated at EMF, which will reduce the effluent volume by evaporation. WTP will later be operated in the baseline configuration when the Pretreatment Facility and the High-Level Waste Vitrification Facility become operational.
The final step in the WTP phased permitting approach is the development of the operational permits for each facility. The Analytical Laboratory completed this step in 2017 and now has an operating permit. This current permit modification provides the operational details for LAW and EMF.
Proposed changes
This permit modification will add a description of operations to the WTP Dangerous Waste Permit for LAW and EMF. The modification describes operations, provides clarification between the baseline and DFLAW configurations, and adds details to ensure the operating permit is compliant with all dangerous waste regulations. The modification proposes changes to the following:
- Unit-Specific Permit Conditions
- Part A Form
- Chapter 3, Waste Analysis Plan
- Chapter 3A, Waste Analysis Plan for the Baseline Configuration
- Chapter 3B, Quality Assurance Project Plan
- Chapter 3C, Waste Analysis Plan for the DFLAW Configuration
- Chapter 4, Process Information
- Chapter 4E, Low-Activity Waste Facility
- Chapter 4G, Direct Feed Low-Activity Waste (Effluent Management Facility)
- Chapter 4I, Balance of Facilities
- Chapter 6, Procedures to Prevent Hazards
- Chapter 6A, Inspection Plan
- Chapter 7, Building Emergency Plan
- Chapter 8, Personnel Training
- Updates to multiple appendices, including the interim compliance schedules
Interim compliance schedule items completed with this permit modification include: LAW-3 through LAW-7, LAW-11, LAW-14, LAW-15, LAW-17, LAW-25, LAW-45, as well as EMF-3 through EMF-7, EMF-11, and EMF-45.

The permittees are the U.S. Department of Energy Office of River Protection and Bechtel National, Inc. The WTP is located on the Hanford Site in Southeastern Washington. The plant will immobilize in glass 56 million gallons of dangerous radioactive and chemical waste stored in 177 underground storage tanks at Hanford. This modification is the second portion of a Class 3 permit modification (8C.2017.3D) and focuses on proposed modifications to the Interim Compliance Schedule for the WTP Permit. The proposed Interim Compliance Schedule has been revised to align the dates with the final Consent Decree filed in U.S. District Court, Eastern District of Washington (Case 2:08-CV-5085 - RMP, Document 222) on March 11, 2016. The permittees held a public comment period for the first portion of the Class 3 modification from March 6 through May 5, 2017, with a public meeting held March 30. We are proposing additional modifications to the Interim Compliance Schedule and to permit conditions following the first comment period.
