            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 066)
Location: Erwin, Tennessee
Also known as: Davison Chemical, Nuclear Fuels Services
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 W.R. Grace (Tennessee).
Class(es) Added to the SEC
Atomic Weapons Employer (AWE) employees who were monitored or should have been monitored for potential exposure to thorium while working in any of the 100 series buildings or Buildings 220, 230, 233, 234, 301, or 310 at the W.R. Grace site at Erwin, Tennessee for a number of work days aggregating at least 250 work days from January 1, 1958, through December 31, 1970, or in combination with work days within the parameters established for one or more other classes of employees in the Special Exposure Cohort.
**Note:** This class was established by Petition 82Petitions Qualified for Evaluation

January 30, 2007Summary of Information in Petition
**Location:** Erwin, Tennessee
**Job Titles and/or Job Duties:** All workers
**Period of Employment:** January 1, 1958 through December 31, 1970
**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

SEC Petitions Not Qualifying for Evaluation
In addition to the petition above, two petitions were received but did not qualify for evaluation because they did not meet the minimum petition requirements.
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.

                        January 16, 2013Technical 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
An Exposure Matrix for W.R. Grace and Company in Erwin, Tennessee [586 KB (43 pages)]
            Revised September 16, 2011
**Revision Includes:** Modifies the residual period guidance. This includes a recommendation to not assign plutonium and thorium exposures during the residual period; modified the methodology for assigning external dose and uranium exposure during the residual period; and revised the use of monitoring records during the residual period. Also, an error was corrected for 238U in Table 3-3. In addition, references were updated as appropriate and various minor technical edits were made throughout this document. The SEC language in Section 1.0 was moved to a newly created Sections 1.3. These changes were made to Sections 3.1, 3.1.3, 4.7, 5.1, 5.2, and the references. Incorporates formal internal and NIOSH review comments. Constitutes a total rewrite of the document.
