Revision Includes: Modifies the residual period guidance. This includes a recommendation to not assign plutonium and thorium exposures during the residual period; modified the methodology for assigning external dose and uranium exposure during the residual period; and revised the use of monitoring records during the residual period. Also, an error was corrected for 238U in Table 3-3. In addition, references were updated as appropriate and various minor technical edits were made throughout this document. The SEC language in Section 1.0 was moved to a newly created Sections 1.3. These changes were made to Sections 3.1, 3.1.3, 4.7, 5.1, 5.2, and the references. Incorporates formal internal and NIOSH review comments. Constitutes a total rewrite of the document.

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.

At the current time, no PERs or PEPs specific to W.R. Grace have been developed. However, we have developed PERs and PEPs that pertain to multiple sites. To view all PERs and PEPs that have been developed, please refer to the Program Evaluation Reports (PERs) and Program Evaluation Plans (PEPs) 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.

Below are the Worker Outreach Activities for W.R. Grace:
