Added an Attributions and Annotations Section on page 10, updated NIOSH required language on page 5 in Section 1.1, and ORAU
team references on pages 8 and 11. Now uses term, "favorable to claimant" on pages 6, 9, and 10 in Sections

Revision Includes: Removes all surrogate data except the data from MCW.
Adds new material located since the last revision. Includes a correction factor to account
for worker-radiation source geometry to be applied to the measured and missed photon dose
for operators, material handlers and trade workers to avoid an underestimate of dose.
Organs most affected by this are those in the lower torso (stomach, pancreas, ovaries, etc.).
DCAS-TIB-0013 was included as a reference and used to determine this geometric correction
factor of 2.1. Incorporates responses and commitments based on SC&A and Advisory
Board Working Group issues. Incorporates formal internal and NIOSH review comments. Constitutes
a total rewrite of the document.

Technical Information Bulletins (TIBs)
At the current time, there are no TIBs for Weldon Spring Plant

Program Evaluation Reports (PERs) and Program Evaluation Plans (PEPs)
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.
At the current time, no PERs or PEPs specific to Weldon Spring Plant have been developed. However, we have developed PERs and PEPs that pertain to multiple sites. To view all PERs and PEPs that have been developed, please refer to the Program Evaluation Reports (PERs) and Program Evaluation Plans (PEPs) page.

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.
Below are the Worker Outreach Activities for the Weldon Spring Plant:

Advisory Board Work Group on Weldon Spring Plant
This Work Group is responsible for reviewing the Weldon Spring Site Profile, SEC petitions from Weldon Spring petitioners, the NIOSH Evaluation Report of the petition, and the SC&A Review of the Weldon Spring Site Profile. It is also responsible for considering issues raised by the Board's contractor (SC&A) concerning the Site Profile and SEC petitions, 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 recommendations to the Board on whether a class should be added to the SEC.
