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 compensability of a completed dose reconstruction may be effected, 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.

PER 31: Y-12 TBD Revisions
PDF 17 KB (2 pages)
Document Number: OCAS-PER-0031 Rev-00
About this Document: Document to determine which
previously completed claims require
evaluation for the effect of revising the
Y-12 Plant TBD.
Approved: December 18, 2007
Summary: There were 693 Y-12 claims completed prior to January 12, 2006, with a probability of causation below 50%. The dose reconstruction methodology of each will be reviewed to determine if a new dose reconstruction is necessary to determine if the revisions increase the dose estimate. NIOSH will review these dose reconstructions to determine if they meet the criterion listed in this PER. NIOSH will provide DOL with the list of 693 claims as well as a determination on each claim as to whether a new dose estimate is required. Documentation for each claim not requiring a new dose reconstruction will provide the basis for that determination.

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 Y-12 Plant:
- April 5, 2005
Meeting with Security, Police, and Fire Professionals of America; International Guards Union of America

Special Exposure Cohort Petition Information for the Y-12 Plant
- Submissions Not Qualifying
for Evaluation
In addition to the petition listed below, two additional
submissions were received but did not qualify for evaluation
because they did not meet the minimum petition requirements.
- Classes Not Added to the SEC
- Y-12 Plant (Statisticians)--The Secretary of HHS determined that the following employees do not meet the statutory criteria for addition to the SEC as authorized under EEOICPA: Statisticians who performed statistical analysis of biological experiments (working within the Oak Ridge National Laboratory Biological Sciences Division) in all locations
at the Y-12 Plant in Oak Ridge, Tennessee, who were employed by the Department of Energy or its contractors between January 1, 1958, and June 30, 1958.
- Classes Added to the
SEC
- Y-12 Plant (March
1943 through December 1947)--Department
of Energy (DOE) employees or DOE contractor or subcontractor
employees who worked in uranium enrichment operations
or other radiological activities at the Y-12 facility
in Oak Ridge, Tennessee from March 1943 through
December 1947 and who were employed for a number
of work days aggregating at least 250 work days,
either solely under this employment or in combination
with work days of employment occurring within the
parameters (excluding aggregate work day requirements)
established for other classes of employees included
in the SEC
- Y-12 Plant (January
1948 through December 1957)--Department
of Energy (DOE) employees or DOE contractor or subcontractor
employees who were monitored or should have been
monitored for: (1) Thorium exposures while working
in Building 9201-3, 9202, 9204-1, 9204-3, 9206,
or 9212 at Y-12 for a number of work days aggregating
at least 250 work days from January 1948 through
December 1957 or in combination with work days within
the parameters (excluding aggregate work day requirements)
established for one or more classes of employees
in the SEC; or (2) Radionuclide exposures associated
with cyclotron operations in Building 9201-2 at
Y-12 for a number of work days aggregating at least
250 work days from January 1948 through December
1957 or in combination with work days within the
parameters (excluding aggregate work day requirements)
established for one or more classes of employees
in the SEC.
- Y-12 Plant (March 1, 1943 through December 31, 1947)--All employees of the Department of Energy (DOE), its predecessor agencies, and DOE contractors or subcontractors who worked at the Y-12 Plant in Oak Ridge, Tennessee from March 1, 1943 through December 31, 1947, for a number of work days aggregating at least 250 work days occurring either solely under this employment or in combination with work days within the parameters established for one or more other classes of employees in the Special Exposure Cohort.
- Petition Information
NOTE: Four separate SEC Petitions have been
received for the Y-12 Plant. Because the period of
employment for three of the petitions overlapped,
those three petitions were merged into one petition
for evaluation purposes.
