Special Exposure Cohort Petition Information

The Special Exposure Cohort (SEC) is a unique category of employees established by the Act (42 CFR Part 83). Claims compensated under the SEC do not have to go through the dose reconstruction process. To qualify for compensation under the SEC, a covered employee must meet specific requirements (e.g., must have at least one of 22 “specified cancers,” and have worked for a specified time period at one of the SEC sites). Classes of employees and work sites can be considered for addition to the SEC through a NIOSH petition process. More information about the Special Exposure Cohort can be found on our Frequently Asked Questions page.

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

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.

    About this Document: Determines the effect of the revision to dose reconstruction methods for the Norton Company, including revision to residual period contamination depletion rate, on previously completed claims.

    Summary: All claims that had previously been completed with a probability of causation (POC) less than 50% were reviewed. This population included 54 claims. Nine of these claims had employment only prior to 1962 and were removed from further evaluation. One claim had been completed using the new template and was also removed from further evaluation. One of the remaining claims was returned to NIOSH by the Department of Labor (DOL) for a new dose estimate during the evaluation. This claim was completed with the new template and was removed from further evaluation under this PER.

    The dose for the remaining 43 claims was recalculated using the template and all applicable approved dose reconstruction methods. As a result, all 43 claims resulted in a probability of causation below 45%. NIOSH will provide DOL with the list of all the claims evaluated under this PER.
