Grand Junction Facilities

(Site Profile/Docket Number 218)

Location: Grand Junction, Colorado

Special Exposure Cohort Petition Information

The Special Exposure Cohort (SEC) is a unique category of employees established by The Act (42 CFR Part 83). Claims compensated under the SEC do not have to go through the dose reconstruction process. To qualify for compensation under the SEC, a covered employee must meet specific requirements (e.g., must have at least one of 22 "specified cancers," and have worked for a specified time period at one of the SEC sites). Classes of employees and work sites can be considered for addition to the SEC through a NIOSH petition process. More information about the Special Exposure Cohort can be found on our Frequently Asked Questions page.

Worker Outreach Activities

Based on a recommendation from the Advisory Board to provide workers and site experts with opportunities to participate in developing the technical documents used in dose reconstruction, NIOSH established a Worker Outreach Program.

At Worker Outreach Meetings, current and former DOE and AWE employees have opportunities to obtain information about Site Profiles, Technical Basis Documents, and Technical Information Bulletins, and to provide information for consideration and possible use in dose reconstruction. This process is valuable to ensure that the technical documents used in dose reconstruction contain correct and useful information.

Worker Outreach Activities for the Grand Junction Facilities:

No activities are scheduled at this time.

Advisory Board Work Group on Grand Junction Facilities

This Work Group is responsible for advising the Board in its continued review of the Grand Junction Facility Special Exposure Cohort (SEC) petition, the NIOSH Evaluation Report of the petition, and for any resulting or subsequent reviews of the dose reconstruction methods for this site. The Work Group may recommend to the Board SEC-petition actions and/or advice to NIOSH on possible changes to the dose reconstruction methods, as appropriate.

Work Group Members:

  • R. William Field, Ph.D., M.S. (Chair)
  • James E. Lockey, M.D., M.S.

Advisory Board and NIOSH Discussions on Grand Junction Facilities

The Grand Junction Facilities discussion papers listed below are working documents prepared by NIOSH or its contractor for use in discussions with the Advisory Board on Radiation and Worker Health or its Working Groups or Subcommittees. Draft, preliminary, interim, and white paper documents are not final NIOSH or Advisory Board (or their technical support and review contractors) positions unless specifically marked as such. These documents represent preliminary positions taken on technical issues prepared by NIOSH or its contractor.

The discussion papers have been reviewed to identify and redact any information that is protected by the Privacy Act 5 USC §552a and have been cleared for distribution.

Program Evaluation Plans (PEPs) and Program Evaluation Reports (PERs)

NIOSH is committed to applying the best available science in dose reconstructions. In keeping with this commitment, completed cases with probabilities of causation less than 50% are reviewed as relevant new information becomes available. The results of these reviews are described in a Program Evaluation Report (PER). The PER details the effect, if any, of the new information on the completed dose reconstruction. If it appears that the new information may result in an increase in dose for a completed dose reconstruction with a probability of causation of less than 50%, NIOSH is committed to working with the Department of Labor to reopen and rework the dose reconstruction, as appropriate. A Program Evaluation Plan (PEP) describes plans for evaluating specific program details or issues.

To view all PERs and PEPs that have been developed, please refer to the Program Evaluation Reports (PERs) and Program Evaluation Plans (PEPs) page.

    About this Document: Determines the effect on previously completed claims due to changes to Grand Junction Operations Office dose reconstructions.

    Summary: Potentially effected Grand Junction Operations Office claims were reviewed based upon additional information discovered while evaluating an SEC petition. NIOSH will notify DOL of all results and request a return of the one claim that would now result in a probability of causation greater than 50%.
