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.
Open/Active SEC Petitions
To date, there are no open/active SEC petitions from W.R. Grace (Tennessee).

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.
Worker Outreach Activities for the Allied Chemical Corporation:
- April 6, 2011 Meeting with representatives of United Steelworkers of America (USW) Local 9677 and former workers from W.R. Grace – Erwin, Tennessee (Nuclear Fuels Services) Final Minutes [365 KB (20 pages)]
- July 21, 2005 Meeting with United Steelworkers of America Local 5-3677 Final Minutes [64 KB (14 pages)]
If the energy employee's personal radiation information is incomplete, NIOSH will use other sources to estimate the radiation dose. This may involve using technical documents called Site Profiles, Technical Basis Documents, and Technical Information Bulletins.
