            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 162)
Location: Saginaw, Michigan
Also Known As: APV Chemical Company
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 Baker-Perkins Company.
Classes Not Added to the SEC
All Atomic Weapons Employer (AWE) employees who performed Atomic Energy Commission work at Baker-Perkins Company, in Saginaw, Michigan, from May 14, 1956 through May 18, 1956.
**Note:** This class was established from Petition 128
Petitions Qualified for Evaluation
Below is a list of the petitions that qualified for evaluation. Select a petition on the list to view the table for that particular petition.

	Petition 128
Steps in Petition Process:
Petition Details:Date Received
September 9, 2008Date Qualified for Evaluation
March 13, 2009Summary of Information in Petition
**Job Titles and/or Job Duties:** All employees
**Period of Employment:** November 7, 1948 through July 12, 1968
**Location:** Saginaw, Michigan
**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. Therefore, as this petition proceeds through the SEC petition process and if an SEC class is proposed, the proposed class may not exactly match the above information.Copy of the Petition Received

Transcript [741 KB (335 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
Technical Basis Document for the Baker-Perkins Company [335 KB (14 pages)]
            Revised May 1, 2012
**About this Document:** Revises internal dose model. Provides more detail description of quantity of uranium and time line of events. Incorporate review comments.
Advisory Board and NIOSH Discussions on Baker-Perkins Co.
The Baker-Perkins Co. 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 has been cleared for distribution.

Technical Basis Document for the Baker-Perkins Company [267 KB (12 pages)]
            February 17, 2011
**About this Document:** This technical basis is established for the reconstruction of radiation doses of workers at AWE sites which refined uranium under contract to the United States government from 1942 to 1958. This document covers the generic aspects of uranium refining and the data are useful where no other dosimetry data exist. Site specific appendices are included that provide information that apply to only the identified site (Appendix P is the site specific Appendix for Baker-Perkins Co.).
