OCAS-PER-030, Subtasks 1–3

EVALUATION OF SAVANNAH RIVER 

SITE (SRS) TBD REVISIONS

SC&A Report Dated July 1, 2013

Presented to the

Advisory Board’s Procedures Review Subcommittee

November 7, 2013

1
OCAS-PER-030 Summary

• PER-030 (2007) was issued to address several 

changes in the SRS TBD (ORAUT-TKBS-0003):

 07/15/2003, Rev. 00

 08/21/2003, Rev. 01 

 10/29/2004, Rev. 02

 04/05/2005, Rev. 03

• In addition, the Occupational Medical Dose 

Section was revised as a separate document 

and issued on November 30, 2009, Rev. 04.

2
NIOSH Issues

• The TBD changes could potentially increase 

assigned dose to claimants whose claims had 

previously been processed, with a resulting 

probability of causation (POC) <50%, using an 

earlier version of the SRS TBD because of the 

following revisions:

 A reduction for 1.5 L recorded bioassay should 

not be applied

 Environmental plutonium and uranium 

headings transposed in table

3
NIOSH Issues (continued)

 Use 2,500 hours per year environmental

exposure

 Revised Environmental Plutonium Intakes

• The Occupational Medical Dose section was 

revised in 2009, after PER-030 was issued in 

2007.

4
NIOSH’s Corrective Action

• NIOSH provided a plan of corrective action to 

resolve the issues created by the revisions (as 

of 2007) by requesting that the claims 

impacted by the revisions be returned for a 

new dose estimate.

5
NIOSH Number of Claims

• NISOH identified 54 SRS claims with a POC 

<50% that were potentially impacted due to 

the issuance of the August 21, 2003, TBD 

revision.

• NIOSH stated that the changes in the 2004 

and 2005 revisions were phase 

implementations (i.e., there were reserved 

sections where additional recommendations 

were later added) and impacted claims were 

held until these sections were completed.

6
SC&A’s Subtasks 1 & 2

• SC&A performed a paragraph-by-paragraph 

comparison of each TBD revision to the 

former TBD (i.e., SC&A compared Rev. 01 of 

August 21, 2003, to the contents of Rev. 00, 

July 15, 2003, etc.) to determine if there 

were any changes in the later revision that 

could potentially increase the assigned dose. 

7
SC&A’s Subtasks 1 & 2 (continued)

• SC&A did not locate any changes in the TBDs 

through 2007 that would potentially increase 

the assigned dose, except the issues 

previously listed above, as addressed by 

OCAS-PER-030.

• SC&A evaluated the revised Occupational 

Medical Dose section of 2009 and found that 

there were changes that could increase the 

assigned dose.

8
SC&A Finding #1

• Finding #1: Concerns with Phased 

Implementation – What documentation is 

available to verify that the SRS claims that 

were held waiting for the reserved sections to 

be completed were (or will be) evaluated 

when the new information became available? 

9
SC&A Finding #2

• Finding #2: 2009 Revised Occupational 

Medical Dose Section – Considering that 

there were significant changes in Rev. 04, it 

appears that an additional PER concerning 

Rev. 04 of the SRS Occupational Medical 

profile would be appropriate.

10
SC&A’s Subtask 3

(Number of claims)

• SC&A used the NOCTS database system to 

verify that there were 54 SRS claims impacted 

by OCAS-PER-030. It is recommended that 

SC&A review the 54 claims as described in 

Subtask 4 below.

11
SC&A’s Subtask 4

Selection of DRs to Audit

• NIOSH has completed the evaluation of the 

54 potentially impacted claims under OCASPER-030 and found none met one or more 

of the four TBD changes/criteria that would 

affect dose.

12
Selection of DRs to Audit

(continued)

• It is recommended that SC&A sample the 54 

applicable claims and evaluate some of them 

to verify that changes in the SRS TBD did not 

impact the dose assignments as per criteria 

set forth in OCAS-PER-030.

• SC&A recommends that at least 5–15 claims 

be subjected to this detailed analysis.
