Dear Mr. President: 

Pursuant to the Energy Employees Occupational Illness Compensation Program Act of 2000 

(EEOICPA) and 42 C.F.R. pt. 83, a petition was filed on behalf of workers at the West Valley 

Demonstration Project in West Valley, New York, to be added to the Special Exposure Cohort 

(SEC). 

The Centers for Disease Control and Prevention’s (CDC) National Institute for Occupational Safety 

and Health (NIOSH) completed the evaluation of the SEC petition 00252 for the time period from 

January 1, 1969, through December 31, 1973, and presented its findings to the Advisory Board on 

Radiation and Worker Health (Board) during the Board’s meeting on August 21, 2019, in Oak Ridge, 

Tennessee. The Board considered the petition, and on September 25, 2019, I received the Board’s 

recommendation concerning this petition. I have also received the deliberations, findings, and 

recommendations of the Director of NIOSH and the Director of CDC. Based on this information, I 

have designated the following class for addition to the SEC, as authorized under EEOICPA, 42 

U.S.C. § 7384q: 

“All Atomic Weapons Employees who worked at the West Valley Demonstration Project 

in West Valley, New York, during the period January 1, 1969, through December 31, 

1973, 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.” 

The criteria and findings upon which this determination is based are provided in the enclosed report.

Designation of Additional Members of the 

Special Exposure Cohort under the 

Energy Employees Occupational Illness Compensation Program Act of 2000 

Designating a Class of Employees from 

West Valley Demonstration Project 

West Valley, New York 

HHS Special Exposure Cohort Designation: West Valley Demonstration Project, West Valley, New York [SEC 00252] 
 

 

 

 

 

 

I. Designation 

I, Alex M. Azar II, Secretary of Health and Human Services (HHS), designate the class of 

employees defined in Section II of this report for addition to the Special Exposure Cohort (SEC), 

as authorized under the Energy Employees Occupational Illness Compensation Program Act of 

2000 (EEOICPA), 42 U.S.C. § 7384q. 

October 25, 2019 [Signature on File] 

Date Alex M. Azar II, Secretary 

II. Employee Class Definition 

All Atomic Weapons Employees who worked at the West Valley Demonstration Project in 

West Valley, New York, during the period from January 1, 1969, through December 31, 

1973, 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. 

III. Designation Criteria and Recommendations 

Pursuant to 42 U.S.C. § 7384q, for the class defined in Section II of this report, the Secretary has 

determined, and the Advisory Board on Radiation and Worker Health (Board) has recommended, 

that 

(1) it is not feasible to estimate with sufficient accuracy the radiation dose that the class 

received; and 

(2) there is a reasonable likelihood that such radiation dose may have endangered the 

health of members of the class. 

The SEC final rule states in 42 C.F.R. § 83.13(c)(1) that it is feasible in two situations to estimate 

the radiation dose that the class received with sufficient accuracy. First, the rule states that 

radiation doses may be estimated with sufficient accuracy if National Institute for Occupational 

Safety and Health (NIOSH) has established that it has access to sufficient information to estimate 

the maximum radiation dose for every type of cancer for which radiation doses are reconstructed 

that could have been incurred under plausible circumstances by any member of the class. 

Alternatively, radiation doses may be estimated with sufficient accuracy if NIOSH has established 

that it has access to sufficient information to estimate the radiation doses of members of the class 

more precisely than a maximum dose estimate. 

NIOSH determined that there is insufficient information to estimate the radiation dose of 

individual members of the class with sufficient accuracy under the two abovementioned situations. 

The Board, pursuant to 42 U.S.C. § 7384q, advised the Secretary to designate the class as an 

addition to the SEC in a letter received by the Secretary on September 25, 2019.

IV. Designation Findings 

Infeasibility of Estimating Radiation Doses with Sufficient Accuracy 

The Secretary established the infeasibility determination for the class of employees covered 

by this report based upon the findings summarized below. 

• NIOSH determined that the principal sources of internal radiation exposures for members 

of the proposed class at the West Valley Demonstration Project (WVDP) included 

inhalation and ingestion exposures to thorium, uranium, neptunium, plutonium, 

americium, curium, and mixed fission and activation products during fuel reprocessing 

activities. 

• NIOSH determined that the sparse uranium bioassay data available for 1969 through 

1973 are inadequate for WVDP claimants. Mixed fission product bioassay data are 

likewise inadequate for 1972 and 1973. Therefore, NIOSH cannot estimate internal doses 

from uranium and mixed fission products with sufficient accuracy for this period. The 

Board concurred with NIOSH’s findings. 

• NIOSH determined that the principal sources of external radiation exposures for 

members of the proposed class included exposure to beta, photon, and neutron radiation 

from various radioactive materials at the WVDP site. 

• NIOSH found that it is not applicable to reconstruct occupational medical dose for 

WVDP employees because medical X-ray procedures were performed at an offsite, nonEEOICPA-covered facility. 

• NIOSH intends to use any personal monitoring data available for an individual claim 

(and that can be interpreted using existing NIOSH dose reconstruction processes or 

procedures) to complete the dose estimate for potential external radiation exposures. 

• Pursuant to 42 C.F.R. § 83.13(c)(1), NIOSH has concluded that there is insufficient 

information to either: (1) estimate the maximum radiation dose, for every type of cancer 

for which radiation doses are reconstructed, that could have been incurred under plausible 

circumstances by any member of the class; or (2) estimate the radiation doses more 

precisely than a maximum dose estimate for the any member of the class at WVDP 

during the period from January 1, 1969, through December 31, 1973. 

• Although NIOSH found that it is not possible to completely reconstruct radiation doses 

for the proposed class, NIOSH intends to use any internal and external monitoring data 

that may become available for an individual claim (and that can be interpreted using 

existing NIOSH dose reconstruction processes or procedures). Therefore, dose 

reconstructions for individuals employed at WVDP during the period from January 1, 

HHS Special Exposure Cohort Designation:

Page 3 
 

 

 

 

1969, through December 31, 1973, but who do not qualify for inclusion in the SEC, may 

be performed using these data as appropriate. 

• NIOSH has determined that members of the class were not exposed to radiation during a 

discrete incident likely to have involved levels of exposure similarly high to those 

occurring during nuclear criticality incidents. However, the evidence reviewed indicates 

that some workers in the class may have accumulated chronic radiation exposures 

through exposure to various radionuclides and from direct exposure to radioactive 

materials. Thus, NIOSH has determined that the health of the proposed class of 

employees may have been endangered at WVDP during the period from January 1, 1969, 

through December 31, 1973. 

• The Board concurred with the NIOSH evaluation and recommended the proposed class 

for addition to the SEC. 

Health Endangerment 

The Secretary established the health endangerment determination for the class of employees 

covered by this report based upon the findings summarized below. 

(1) Pursuant to 42 C.F.R. § 83.13(c)(3), NIOSH established that there is a reasonable 

likelihood that such radiation doses may have endangered the health of members of the 

class. Pursuant to 42 C.F.R. § 83.13(c)(3)(ii), NIOSH specified a minimum duration of 

employment to satisfy this health endangerment criterion as “having been employed for a 

number of work days aggregating at least 250 work days within the parameters 

established for this class or in combination with work days within the parameters 

established for one or more other classes of employees in the Cohort.” 

(2) The Board concurred with NIOSH’s finding that the health of the class may have 

been endangered and defined the class according to the 250-work day requirement 

specified under 42 C.F.R. § 83.13(c)(3)(ii). 

V. Effect and Effective Date of Designation 

The Secretary submits this report on the designation of one additional class to the SEC for 

review by Congress, pursuant to 42 U.S.C. §§ 7384l(14)(C)(ii) and 7384q(c)(2)(A), as 

amended by the Ronald W. Reagan National Defense Authorization Act for Fiscal Year 

2005, Pub. L. No. 108-375 (codified as amended in scattered sections of 42 U.S.C.). Pursuant 

to 42 U.S.C. § 7384l(14)(C)(ii), as amended by the Ronald W. Reagan National Defense 

Authorization Act for Fiscal Year 2005, Pub. L. No. 108-375 (codified as amended in 

scattered sections of 42 U.S.C.), the designation in this report will become effective 30 days 

after the date of this report’s submission to Congress “unless Congress otherwise provides.”

VI. Administrative Review of Designation 

The health endangerment determination of the designation provided in this report may be 

subject to an administrative review within HHS, pursuant to 42 C.F.R. § 83.18(a). On the 

basis of such a review, if the Secretary decides to expand the class of employees covered by 

this designation, the Secretary would transmit a supplementary report to Congress providing 

the expanded employee class definition and the criteria and findings on which the decision 

was based.
