Weldon Spring Raffinate Pits

(Site Profile/Docket Number 116)

Location: Weldon Spring, Missouri

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

Please see the Weldon Spring Plant page for information on open/active SEC petitions.

Please see the Weldon Spring Plant page for information on classes not added to the SEC.

Petitions Qualified for Evaluation

Please see the Weldon Spring Plant page for information on petitions qualified 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.

Please see the Weldon Spring Plant page for information on worker outreach activities.

Advisory Board Work Group on Weldon Spring Plant

This Work Group is responsible for reviewing the Weldon Spring Plant Site Profile, the SEC petition from Weldon Spring Plant petitioners, the NIOSH Evaluation Report of the petition, the SC&A Review of the Weldon Spring 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.

Sites currently being considered by the Work Group include: Weldon Spring Plant, Weldon Spring Quarry, and Weldon Spring Raffinate Pits.

Meeting information (including agendas and transcripts) for this Work Group can be found on either the individual site pages or the Advisory Board and Public Meetings page.

Work Group Members:

• Richard A. Lemen, Ph.D., M.S.P.H. (Chair)

• R. William Field, Ph.D., M.S.

• Paul L. Ziemer, Ph.D.

Meeting Information:

Please see the Weldon Spring Plant page for meeting information.

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.

Please see the Weldon Spring Plant page for the list of technical documents.

Advisory Board and NIOSH Comments and Discussion Papers on Weldon Spring Raffinate Pits

The Weldon Spring Raffinate Pits discussion papers are working documents prepared by NIOSH or its contractor for use in discussions with the Advisory Board on Radiation and Worker Health or its Working Groups or Subcommittees. Draft, preliminary, interim, and white paper documents are not final NIOSH or Advisory Board (or their technical support and review contractors) positions unless specifically marked as such. These documents represent preliminary positions taken on technical issues prepared by NIOSH or its contractor.

The discussion papers have been reviewed to identify and redact any information that is protected by the Privacy Act 5 USC §552a and has been cleared for distribution.

Please see the Weldon Spring Plant page for a list of Advisory Board and NIOSH comments and discussion papers.

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.

Please see the Weldon Spring Plant page for a list of PEPs and PERs.
