Energy Employees Occupational Illness Compensation Program Act of 2000 

Designating a Class of Employees from 

Standard Oil Development 

Linden, New Jersey 

HHS Special Exposure Cohort Designation: 

Standard Oil Development Company, Linden, New Jersey 
I. Designation 

I, Kathleen Sebelius, Secretary of Health and Human Services, 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. 

 ______June 18, 2009___ __[Signature on File]______ 

 Date Kathleen Sebelius

II. Employee Class Definition 

All AWE employees of the Standard Oil Development Company in Linden, New 

Jersey, during the period from August 13, 1942 through December 31, 1945, while 

working for a number of work days aggregating at least 250 work days, 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 SEC. 

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 

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. 

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 May 20, 

2009.

IV. Designation Findings 

Feasibility of Estimating Radiation Doses with Sufficient Accuracy

The Secretary established the feasibility determination for the class of employees 

covered by this report based upon the findings summarized below. 

 NIOSH determined that members of this class may have received internal and 

external radiation exposures through the handling of natural and enriched 

uranium during development activities associated with the centrifuge pilot plant, 

and during the handling of various uranium compounds associated with uranium 

procurement and uranium production research and development. 

 NIOSH has no uranium bioassay results or area monitoring for the covered 

period that would support reconstructing the internal dose for Standard Oil 

Development Company (SODC) workers associated with the unique centrifuge 

work, or the uranium procurement and uranium production research and 

development work performed at SODC. NIOSH also determined that it did not 

have access to source, or source term, information associated with the SODC 

work to bound potential internal exposures during the period from August 13, 

1942 through December 31, 1945, and therefore NIOSH finds that it is not 

feasible to estimate, with sufficient accuracy, the total internal dose for the class 

of employees covered by this evaluation. 

 NIOSH has no personal or area monitoring for the covered period that would 

support reconstructing the external dose for Standard Oil Development Company 

(SODC) workers associated with the unique centrifuge work, or the uranium 

procurement and uranium production research and development work performed 

at SODC. NIOSH also determined that it did not have access to source, or 

source term, information associated with the SODC work to bound potential 

external exposures during the period from August 13, 1942 through December 

31, 1945, and therefore NIOSH finds that it is not feasible to estimate, with 

sufficient accuracy, the total external dose for the class of employees covered by 

this evaluation. 

 NIOSH lacks sufficient information, which includes specific biological monitoring 

data, sufficient air monitoring information, sufficient process and radiological 

source information, and surrogate data from similar operations at other sites that 

would allow it to estimate the potential internal or external exposures to natural or 

enriched uranium, or uranium compounds, to which the proposed class may 

have been subject. However, NIOSH finds that it is possible to reconstruct 

occupational medical dose. 

 NIOSH has documented that it cannot complete the dose reconstructions related 

to this petition with sufficient accuracy. The basis of this finding demonstrates 

that NIOSH does not have access to sufficient information to estimate either the 

maximum radiation dose incurred by any member of the class or to estimate 

such radiation doses more precisely than a maximum dose estimate.

 Pursuant to 42 C.F.R. § 83.13(c)(1), NIOSH determined 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 of members of the class more precisely than a 

maximum dose estimate. 

 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 (excluding 

aggregate work day requirements) established for one or more other classes 

of employees in the Cohort.” 

(2) NIOSH did not identify any evidence from the petitioners or from other 

resources that would establish that the class was exposed to radiation during 

a discrete incident likely to have involved exceptionally high-level exposures, 

such as a nuclear criticality incident, as defined under 42 C.F.R. § 

83.13(c)(3)(i). 

(3) 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.
