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.

Program Evaluation Report: Blockson TBD Revision
this document in PDF PDF 14 KB (1 page)

Document Number: OCAS-PER-0020 Rev-00

About this Document: New document to determine which previously completed claims require evaluation for the effect of revising the Blockson TBD.

Approved: July 31, 2007

Summary: It is not possible to determine the magnitude of the change to dose without a new dose estimate. Since (as of issuance of this PER) no Blockson Chemical Company claims have yet been completed with the newest revision to the TBD, NIOSH is requesting that all Blockson Chemical Company claims with a Probability of Causation less than 50% be returned for a new estimate. A list of the entire population of the ninety-one potentially affected claims is attached. A new dose reconstruction will be completed for each of the claims using the latest revision to the Blockson TBD.

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 Blockson Chemical Company:
