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

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 compensability of a completed dose reconstruction may be effected, 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.

  • PER 10: The Effect of Rocky Flats Neutron Dose Reconstruction Project Data
    this document in PDF PDF 21 KB (2 pages)

    Document Number: OCAS-PER-0010 Rev-00

    About this Document: New document to report the impact of data received from the Rocky Flats Plant Neutron Dose Reconstruction Project.

    Approved: April 13, 2007

    Summary: Neutron doses at Rocky Flats were re-evaluated as part of the Rocky Flats Neutron Dose Reconstruction Project (NDRP). These records were provided to OCAS as part of the individual dosimetry records. The application of the NDRP data to dose reconstructions is described in ORAUT-OTIB-0050, Rev. 00.


  • PER 21: Program Evaluation Report: Rocky Flats Plant Dose Reconstruction Method Modifications
    this document in PDF PDF 14 KB (1 page)

    Document Number: OCAS-PER-0021 Rev-00

    About this Document: New document to determine which previously completed claims require evaluation for the effect of revising Rocky Flats Plant TBDs and TIBs.

    Approved: September 20, 2007

    Summary: The Department of Labor indicated they will return all claims to NIOSH that were not determined to be a member of the SEC. Therefore, no evaluation of the modifications to dose reconstruction methodology is necessary. NIOSH will complete a new dose reconstruction for all claims returned by DOL using the current methodology. It should be noted that some of these claims will be unaffected by these modifications and some dose reconstructions may decrease as a result of removing dose associated with the SEC basis.

    The last document to be revised to incorporate changes as a result of the SEC deliberation and designation was the external dose section of the Rocky Flats Technical Basis Document. This document was revised on August 17, 2007. Therefore, the returned claims should consist only of those approved prior to that date. This totals 590 claims, some of which NIOSH previously requested a return based on other PERs.

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.

Below are the Worker Outreach Activities for Rocky Flats Plant:

  • June 23, 2004
    Meeting with United Steelworkers of America Local 8031
