National Bureau of Standards, Van Ness Street

(Site Profile/Docket Number 171)

Location: Washington, D.C.

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 National Bureau of Standards, Van Ness Street.

Classes Not Added to the SEC

  • National Bureau of Standards, Van Ness Street - The Secretary of Energy is granted authority to designate the covered facilities of EEOICPA. On November 30, 2005, the Department of Energy (DOE) published a Federal Register Notice that de-listed NBS as an AWE facility. Based on the DOE determination that NBS is not a covered facility under EEOICPA, NBS employees do not meet the requirement for addition to the SEC. Therefore, the class of NBS was not added to the SEC.

    Note: This determination is made notwithstanding the recommendation of the Advisory Board on Radiation and Worker Health to add certain employees of NBS to the SEC, a decision made at the October 2005 Board meeting, prior to the de-listing of NBS as an AWE under EEOICPA.
