            Cybersecurity Modernization Initiative
                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. For more information and updates, please visit our Cybersecurity Modernization Initiative web page.

(Site Profile/Docket Number 042)
Location: Indian Orchard, Massachusetts
Also Known As: Chapman Valve Manufacturing Co., Crane Co.
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 Chapman Valve.
Classes Not Added to the SEC
All Atomic Weapons Employees who were monitored, or should have been monitored for radiological exposures while performing Atomic Energy Commission work at the Chapman Valve Manufacturing Company (i.e., Building 23 and Dean Street facility) in Indian Orchard, Massachusetts, from January 1, 1948 through December 31, 1949, and from January 1, 1991 through December 31, 1993

**Location:** Indian Orchard, Massachusetts
**Job Titles and/or Job Duties:** Various
**Period of Employment:** From 1948 through 1949 and from 1991-1995 (DOE Remediation)
**Note:** The information above is what qualified for evaluation. During our evaluation of whether dose reconstructions can adequately be completed for the above job titles and period of employment, information may cause NIOSH to change some the dates or job titles/duties.

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.

Issues Matrix for Chapman Valve SEC Petition Evaluation Report [142 KB (5 pages)]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.

Technical Basis Documents

Advisory Board and NIOSH Discussions on Chapman Valve
The Chapman Valve discussion papers listed below 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 have been cleared for distribution.

            December 6, 2006Program 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-0022 Rev-00: Chapman Valve TBD Revision [15 KB (1 page)]
            September 20, 2007
**About this Document:** New document to determine which previously completed claims require evaluation for the effect of revising the Chapman Valve TBD.
**Summary:** There were 31 Chapman Valve claims completed with a probability of causation below 50% prior to the revision to the TBD. Twenty one of these were completed using TIB 4. Because that document describes a higher dose estimate than the revision to the Chapman Valve TBD, no further evaluation is necessary for those claims. The remaining 10 Chapman Valve claims were completed using revision 0 of the Technical Basis Document. NIOSH is requesting that these claims be returned for a new dose estimate. A new dose reconstruction will be completed for each of the claims using the latest revision to the Chapman Valve TBD.Public Comments on Chapman Valve Documents

Technical Basis Document
Revised October 16, 2006 [315 KB (32 pages)]
**Revision Includes:** Replaced boilerplate language in Section 1.0. Added information from February 2005 Worker Outreach meeting. Added additional claim-supplied information. Added discussion supporting assumption of unenriched uranium. Added information regarding the use of a furnace/incinerator and provided a comparison of internal exposures to NUMEC incinerator operators with derived Chapman Valve exposures. Added information on the radiological safety program from a 1952 newspaper account. Added information regarding the month of the previously reported 1948 fire. Provided information developed for SEC petition evaluation report. Reanalyzed intake regimes as directed by OCAS using the largest of the 40 results not associated with the fire, 0.03 mg/L, for each sampling period to calculate a non-fire intake rate, and using the largest result associated with the fire, 0.08 mg/L, for the June 11, 1948 result, and keeping the other results the same as for the nonfire scenario to calculate the fire-associated intake scenario. Both intake scenarios are directed to be constant distributions in IREP. Added a comparison of Chapman derived air concentrations with air concentrations measured at other facilities. Added figures showing location of chip burner and dust, debris and soil sampling.
Corrected two residual radioactivity external exposure values (increased rates by a factor of 2). Incorporated formal internal review comments, NIOSH and DOL comments. This revision results in an increase in assigned dose.
