NOC approval order for WTP
Nov. 29, 2021 – Dec. 31, 2021
We held a 30-day comment period for Approval Order DE02NWP-002, Revision 3. The permittee, the U.S. Department of Energy (USDOE), requested revisions to the air Notice of Construction Approval Order for the Waste Treatment Plant (WTP) to address updated waste composition and estimated emissions. These changes were for the Low-Activity Waste (LAW) and Laboratory (LAB) portions of the WTP. This permit revision does not authorize any physical changes to LAW or LAB design. This Approval Order addressed four items:
- Waste composition and the resulting air emissions have been updated for the most recent Direct Feed LAW design.
- USDOE and Ecology have agreed on the composition of simulant used to test the LAW facility before tank waste is treated. Emissions from commissioning and testing with this simulant will now be covered by the Approval Order.
- Air emissions have been modeled to the new ambient air boundary. The new boundary is closer to the WTP site and modeling now includes areas which were previously excluded.
- Removal of acid gases, primarily hydrogen chloride and hydrogen fluoride, is now identified as primarily taking place in the wet control devices instead of the carbon bed adsorber for LAW. The carbon bed adsorber will still be constructed and operated for removal of volatile organic chemicals and organic toxic air pollutants.

242-A Evaporator Class 3 permit modification
Feb. 8, 2021 – March 25, 2021 – Response to comments
We held a 45-day public comment period addressing proposed modifications to the Hanford Dangerous Waste Permit for the 242-A Evaporator.
This modification proposed allowing facility upgrades associated with the new waste transfer lines from the Double-Shell Tank (DST) System to the 242-A Evaporator. The original transfer lines failed pressure tests in 2018 and must be replaced. Specifically, this modification allowed penetrating a wall to install the transfer lines and to perform modifications in the pump-room. These new transfer lines allow 242-A Evaporator to continue to treat DST waste, reducing DST waste volume, and allowing for continued Single-Shell Tank waste retrievals.The transfer lines themselves are administratively controlled by the DST system and are being built under applicable interim status regulations. Construction of the lines is not a part of this permit modification.

WTP Low-Activity Waste and Effluent Management Facilities
July 1, 2019 - Aug. 30, 2019
The U.S. Department of Energy (DOE) Office of River Protection and Bechtel National, Inc. held a 60‑day public comment period to support a requested Class 3 permit modification to the Hanford Waste Treatment and Immobilization Plant (WTP) Dangerous Waste Permit. This modification provides WTP Low-Activity Waste Facility and Effluent Management Facility operating information and proposed operating conditions to Ecology for addition into the existing permit.
Low Activity Waste Pretreatment System (LAWPS) permit modification
May 1, 2019 - June 30, 2019
The Department of Energy (DOE) Office of River Protection held a 60-day public comment period to support a Class 3 modification to the Hanford Dangerous Waste Permit. This modification requested the approval from Ecology to add a new operating unit for the Low Activity Waste Pretreatment System (LAWPS). This operating unit will pretreat (remove cesium and filter out solid particles) double-shell tank waste for subsequent vitrification in the Hanford Tank Waste Treatment and Immobilization Plant Low-activity Waste (LAW) facility.
The planned cesium removal system would be deployed in phases. Phase One would employ a Tank-Side Cesium Removal (TSCR) unit. Phase Two would either use a permanent cesium removal capability, LAWPS facility or an additional TSCR unit to support full operation of the LAW facility. This proposed modification will cover construction activities and operations needed to support the Phase One portion of the project.

Perma-fix Northwest expanded scoping comment period and public meeting
March 4, 2019 to March 25, 2019
The Perma-fix Northwest (PFNW) expanded scoping of a State Environmental Policy Act (SEPA) Environmental Impact Statement (EIS) 21-day public comment period.
As part of the permit renewal process, PFNW submitted a renewal application for its DWR permit to us in 2009. Due to significant changes and updates to the facility and operations since the original permit authorization and EIS in 1998, Ecology, as the lead agency, has determined that there is potential for adverse impacts. Therefore, we've decided to conduct a complete environmental analysis under SEPA to supplement the 1998 EIS.

The draft permit documents were the same, but electronic access for some supporting documents was made available.
WTP Notice of Construction DE16NWP-003 Rev 1 for EMF
June 18, 2018 — July 20, 2018 — Response to comments
We proposed a change to the Non-Radioactive Air Emissions Notice of Construction Approval Order DE16NWP-003 for the Effluent Management Facility (EMF).
The permittee proposed an alternative condition for demonstrating dimethyl mercury emissions sampling compliance. The proposal is to perform monthly dimethyl mercury grab sampling instead of elemental mercury continuous emissions monitoring. The proposed approach does not result in an emissions increase and does not impact ambient air quality standards.
WTP Permit modification for Effluent Management Facility Equipment (BOF-010)
June 4, 2018 – July 18, 2018 — Ecology's Response to Comments
