Sites with Unreviewed DR Methodology Templates and Reports

Meeting of the Subcommittee for Procedure Reviews 

November 16, 2023 

The National Institute for Occupational Safety and Health’s (NIOSH’s) development of a dose 

reconstruction (DR) methodology for many smaller sites under the Energy Employees 

Occupational Illness Compensation Program Act did not consist of the standard technical basis 

document (TBD) or site profile approach. In lieu of a TBD, NIOSH has developed for these sites 

a DR methodology guideline document and a DR template that contain facility-specific data, 

assumptions, and list of documents that provide the basis for the facility-specific data and 

assumptions. The Subcommittee has been provided separately an example of these documents 

from the Peek Street Facility, which have been reviewed by SC&A. 

At the request of the Subcommittee for Procedure Reviews (SPR), NIOSH provided SC&A on 

July 7, 2022, with the list of facilities where DRs are completed using the DR methodology 

guidance and template. Table 1 lists the sites, current and previous versions of the templates, and 

current review status.

(a) The number of revisions to the DR template over the years is not an indication that there were revisions to the DR 

methodology. Revisions to templates are common to update tool integration and references.

(b) Technical basis document/site profile is being developed.

Note: ER = evaluation report; NA = not applicable; PER = program evaluation report; SEC = Special Exposure 

Cohort.

In addition to the DR methodology templates listed in table 1, SC&A has identified several 

NIOSH-issued reports that have not been tasked for review. Table 2 lists those reports along with 

a brief summary of the document content.
