Safety & Resilience

​​​​​​​​​​​In 1980, Oregon passed rules to prohibit disposal of radioactive materials in the state.

Oregon Administrative Rules require that a person cannot hold or place discarded or unwanted radioactive material for more than seven days within the state. Oregon Department of Energy staff will work with Oregon businesses or municipalities that need to dispose of radioactive materials properly. 

Virtually all materials contain some radioactivity, so the rules also help identify materials that could be disposed of or are exempt from the rule, such as slightly radioactive materials that present minimal health hazards. OAR 345-050  outlines the radioactive waste disposal rules in Oregon, with three tables that list the​ disposal exemptions, such as specific exempt elements, naturally occurring elements, and exempt quantities. If you have questions about the administration of these rules, please contact our Nuclear Safety Division.

Rulemaking​

At its May 21, 2020, meeting the Oregon Energy Facility Siting Council initiated a rulemaking project to update administrative rules in OAR chapter 345, division 029 that provide for the rules for enforcement of laws and rules governing the transport and disposal of radioactive materials and waste in Oregon. The objective of the project is to ensure that the rules are sufficient to protect public health and safety and the environment by incentivizing preventative measures, to ensure that radioactive materials or wastes are not improperly transported or disposed of in Oregon, and to require appropriate mitigation or penalties when a violation occurs.

The Council approved the formation of a Rulemaking Advisory Committee (RAC) made up of interested stakeholders to assist the Oregon Department of Energy in the development of proposed rule revisions. The RAC met three times over the summer and fall of 2020, and the department is now finalizing the draft proposed rule revisions it prepared in consideration of the RAC’s feedback. 

On December 7, 2020, ODOE will host a virtual workshop​ to discuss potential revisions to administrative rules for the enforcement of the laws and rules governing the transport and disposal of radioactive waste in Oregon.​ Public participation is welcomed and encouraged. Learn more about the meeting, including how to participate on ODOE's blog​.

February 2020 Notice of Violation: Chemical Waste Management

On February 13, 2020, ODOE issued a Notice of Violation for disposal of radioactive materials in violation of Oregon state law at the Chemical Waste Management hazardous waste landfill near Arlington. In consultation with other State of Oregon agencies, ODOE determined there is no current threat to landfill workers, the public, or the environment from this waste. 

ODOE directed the landfill operator to prepare a risk assessment to formally evaluate potential past, present, and future risk from the waste, and to develop a corrective action plan to outline the processes the company will put in place to prevent this from happening again. Going forward, this incident is also an opportunity to evaluate whether changes are necessary to strengthen Oregon’s radioactive waste disposal law and rules, and our agency’s enforcement options. Read more background here.

​SEPTEMBER 2020 UPDATE

On September 1, 2020, Chemical Waste Management of the Northwest and its team of technical support contractors submitted the detailed risk assessment and corrective action plan. After completing our initial technical review, we have published the documents on our website for public review. ODOE is now accepting public comments on the documents.

The Documents
(summary of documents available below)

Public Comment Period

As of November 8th, 2020, the public comment period on the Risk Assessment and Corrective Action Plan has closed. The Department is reviewing the comments received and will provide responses alongside our formal determination regarding the acceptability of the landfill’s proposed corrective and preventative actions. ​

September 30,​ 2020 Public Meetings

​The Oregon Department of Energy held two public meetings on September 30, 2020 to discuss Chemical Waste Management's submitted documents. The two meetings, one virtual and one in-person, covered the same information.

Summary of the Documents
As described in the documents, CWM's preferred alternative is the in-place closure of the subject TENORM wastes (i.e., leaving the wastes where they are currently buried). CWM's Risk Assessment concluded that even in the event of multiple compounding worst-case scenarios, including a future resident living on a then-closed landfill surface and drinking water from a well at the edge of the landfill, the risk of cancer morbidity due to the radioactivity in these wastes would be up to one in a million, but likely far less. Future concentrations in groundwater are also calculated to be well below drinking water standards. The risk to current and future workers resulting from leaving the buried waste in-place was found to be essentially zero. By contrast, CWM's analysis concludes that the decision to exhume the wastes and redispose them at another out-of-state facility would carry a number of uncertain and potentially serious risks resulting from the disturbance of the other hazardous chemical (non-radioactive) wastes legally disposed in the landfill. 

CWM's assessment of the potential risk to landfill workers and members of the public associated with the original disposal of the wastes confirmed ODOE's prior assessment, with OHA and DEQ, that the risk to workers was exceedingly small, even in the unlikely event that the same person had been present at every disposal instance from 2016-2019. In addition, the risk to offsite members of the public would have been small enough as to result in essentially zero adverse health effects.

As part of the corrective action, Waste Management has proposed the installation of an automated radiation portal monitor to screen all future waste loads entering the site. The company has also already enacted a new waste verification process, which involves direct sampling and radiological measurement of representative wastes associated with each waste profile that may contain TENORM, followed by a check with ODOE to seek concurrence that disposal of the wastes represented by the waste profile is legal in Oregon. This two-step verification system will provide the company, and ODOE, greater confidence that the company is taking appropriate safeguards to operate the facility in accordance with Oregon statutes and rules.

  • May 29, 2020: Chemical Waste Management submitted the following preliminary document:
    • ​Leachate Management Practices: This report describes the leachate management system at the landfill and looks specifically at whether the disposed TENORM waste has the potential to enter the leachate system at levels that would be significant to the health of workers or the public. Based on actual recent leachate samples, as well as extensive modeling and risk analysis, the report concludes that radiological doses from the leachate management practices at the landfill are extremely low and do not suggest that any changes are necessary to the current leachate management methods.  The highest calculated effective dose attributed to a hypothetical landfill worker was 0.22 millirem per year, and the annual effective doses to the nearest resident were less than 0.005 millirem.  These calculated doses are orders of magnitude less than the 25 millirem per year recommended dose limit by the American National Standards Institute (ANSI 2009) for unrestricted release of soils from land containing TENORM, and the 100 mrem per year public dose limit set by the Nuclear Regulatory Commission in 10 CFR § 20.1301.
