We are taking steps to continue to modernize and secure our data, applications, and systems. We completed the first phase and restored many of the functions put on pause in May 2021. Now that the first phase is complete, work will resume at a slower pace but will speed up as new systems and applications are brought online.

Rocky Flats Plant
(Site Profile/Docket Number 032)
Location: Golden, Colorado
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
There are currently no open/active SEC petitions from Rocky Flats Plant.

-
April 1, 1952 through December 31, 1983: All employees of the Department of Energy, its predecessor agencies, and their contractors and subcontractors who worked at the Rocky Flats Plant in Golden, Colorado, from April 1, 1952, through December 31, 1983, for a number of work days aggregating at least 250 work days, occurring either solely under this employment or in combination with work days within the parameters established for one or more other classes of employees included in the Special Exposure Cohort.
Note: This class was established from Petition 192
Classes Not Added to the SEC
-
DOE employees or its contractor or subcontractor employees at the Rocky Flats plant in Golden, Colorado, who were exposed to radiation dose from 1967 through 2005 and who were exposed to any radiation dose other than neutron dose from 1952 through 1966.
Note: This class was established from Petition 30
-
January 1, 1984, through December 31, 2005: All employees of the Department of Energy, its predecessor agencies, and their contractors and subcontractors who worked at the Rocky Flats Plant in Golden, Colorado, from January 1, 1984, through December 31, 2005.

SEC Petitions Not Qualifying for Evaluation
In addition to the petitions listed above, four petitions were received but did not qualify for evaluation.
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.

Advisory Board Work Group on Rocky Flats Plant
This Work Group is responsible for reviewing the Rocky Flats Plant Site Profile, the SEC petition from Rocky Flats Plant petitioners, the NIOSH Evaluation Report of the petition, the SC&A Review of the Rocky Flats Plant Site Profile, considering issues raised by the Board’s contractor (SC&A) concerning the Site Profile and the petition Evaluation Report, and for assisting NIOSH and SC&A in the resolution of such issues. The Work Group may recommend to the Board, changes in the Site Profile as appropriate. The Work Group should strive to develop a recommendation to the Board on whether a class should be added to the SEC.

Pre-Decisional Document Policy
Please note that as part of the procedures and processes of the Advisory Board’s Work Groups, several kinds of pre-decisional documents may be developed. These pre-decisional documents, such as white papers, matrices, working drafts, etc., are distributed among Work Group members as research and background tools to facilitate discussion and deliberation. Although discussion during a public meeting may cover pre-decisional documents, these documents often are not further revised or finalized, and thus do not reflect the final determination or evaluation of the Advisory Board and its Work Groups. Additionally, some pre-decisional documents not otherwise posted on the website may contain sensitive information, which would require an interested party to obtain such documents by filing a Freedom of Information Act (FOIA) request with the CDC/ATSDR FOIA office at foiarequests@cdc.gov.
Technical Documents
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.

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.

OCAS-PER-0010 Rev-00: Program Evaluation Report: The Effect of Rocky Flats Neutron Dose Reconstruction Project Data pdf icon[21 KB (2 pages)]
April 13, 2007About this Document: New document to report the impact of data received from the Rocky Flats Plant Neutron Dose Reconstruction Project.
Summary: Neutron doses at Rocky Flats were re-evaluated as part of the Rocky Flats Neutron Dose Reconstruction Project (NDRP). These records were provided to OCAS as part of the individual dosimetry records. The application of the NDRP data to dose reconstructions is described in ORAUT-OTIB-0050, Rev. 00.

OCAS-PER-0021 Rev-00: Program Evaluation Report: Rocky Flats Plant Dose Reconstruction Method Modifications pdf icon[14 KB (1 page)]
September 20, 2007About this Document: New document to determine which previously completed claims require evaluation for the effect of revising Rocky Flats Plant TBDs and TIBs.
Summary: The Department of Labor indicated they will return all claims to NIOSH that were not determined to be a member of the SEC. Therefore, no evaluation of the modifications to dose reconstruction methodology is necessary. NIOSH will complete a new dose reconstruction for all claims returned by DOL using the current methodology. It should be noted that some of these claims will be unaffected by these modifications and some dose reconstructions may decrease as a result of removing dose associated with the SEC basis.
The last document to be revised to incorporate changes as a result of the SEC deliberation and designation was the external dose section of the Rocky Flats Technical Basis Document. This document was revised on August 17, 2007. Therefore, the returned claims should consist only of those approved prior to that date. This totals 590 claims, some of which NIOSH previously requested a return based on other PERs.
