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 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.

    Document Number: DCAS-PER-034 Rev-0

    About this Document: Determines affect of revising the Harshaw TBD on previously completed claims.

    Approved: December 9, 2011

    Summary: Several editorial changes and clarifications were included in the revision however these changes do not affect the estimated dose. Some changes may have decreased the dose but the only significant increase in the dose estimate is caused by an increase in the estimated intake rate for type S uranium from 12/1/1949 to 12/31/1953. The values are listed in Table 5-6 of both revisions.

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 Harshaw Chemical Company:

At the current time, worker outreach activities have not been scheduled.
