MEMO 

DATE: February 23, 2016 

TO: Subcommittee on Procedures Review 

FROM: Kathleen Behling, SC&A 

SUBJECT: Program Evaluation Reports and Technical Guidance Documents Not Tasked for 

SC&A’s Review

Since the last Procedures Review Subcommittee (PRSC) teleconference on April 28, 2015, the 

National Institute for Occupational Safety and Health (NIOSH) has issued numerous program 

evaluation reports (PERs) and technical basis documents (TBDs) that have not been assigned for 

SC&A’s review. In addition, there are two technical information bulletins (OTIBs) and two 

PERs that were issued prior to the last PRSC meeting, which have not been tasked for review. 

Therefore, SC&A has prepared two tables listing these documents for the Subcommittee’s 

consideration. For the unassigned PERs, SC&A has included a recommendation regarding 

whether a review of each PER is warranted. For those PERs for which SC&A is recommending 

that a review be completed, the PER title and justification for this recommendation has been 

highlighted in yellow.

Table 1. PERs Not Assigned for SC&A’s Review as of February 23, 2016

PER Description Doses Changes Cases Impacted SC&A’s Recommendation

DCAS-PER-046: “Nevada Test Site”

Effective Date: 9/22/2015

The Nevada Test Site (NTS) TBD consists of 6 

sections. Revisions have been made to Section 3 

(Occupation Medical Dose), Section 4 

(Environmental Dose), Section 5 (Internal Dose) 

and Section 6 (External Dose) since the issues of 

PER 032 (NTS TBD revisions) on 12/18/2007.

Occupational Medical: Lumbar spine x-rays 

not previously included in TBD, and 

posterior-anterior (PA) chest x-ray dose 

increased between 1960 and 1966 for some 

organs.

Environmental: Increases in assigned doses 

due to (1) addition of correction for 

inhalation of short-lived fission products; 

(2) radon intake estimate from G tunnel and 

unknown tunnels increased prior to 1984; 

and (3) ambient external dose estimates 

extended through 2010.

Internal: Change to isotopic ratios leading to 

an increase in assigned intakes from 

plutonium-238 (Pu-238) and americium-241 

(Am-241).

External: Misinterpretation of beta-to-photon 

ratio to be assigned prior to 1966.

2,316 initially identified 

cases.

After removal of cases due to 

compensation under the 

Special Exposure Cohort 

(SEC) and specifics 

associated with the current 

TBD revisions, 590 cases

remained that required 

reevaluation.

SC&A recommends that this 

PER be reviewed due to the 

numerous modifications that 

affected all exposure 

pathways and the number of 

cases impacted by these 

changes.

PER Description Doses Changes Cases Impacted SC&A’s Recommendation

DCAS-PER-054: Carborundum

Effective Date: 7/25/2014

No TBD exists for the Carborundum site. Methods 

in one dose reconstruction were often carried 

forward to the next as applicable. Revision to 

ORAUT-OTIB-0070 on 3/5/2012 could affect 

previously completed Carborundum claims. In 

addition, the covered period for the site was 

increased to include 1943.

Due to the additional year of exposure at the 

beginning of the covered period, an increase 

in dose could impact nearly all Carborundum 

claims. The revised OTIB-0070 depletion

factors could also result in an increase in 

dose.

58 cases were identified and 

reevaluated

SC&A recommends that this 

PER be reviewed due to the 

fact that no formal dose 

reconstruction (DR)

methodology exists for 

Carborundum cases and to 

assess consistency of the DR 

methods that were “often 

carried forward to the next 

as applicable.” An SEC 

petition has been submitted 

for this site. NIOSH 

evaluated this petition and 

has proposed a revised DR 

methodology, which has 

been reviewed by SC&A but 

not yet considered by the 

Board. Nevertheless, we 

believe that the earlier PER 

merits review.

DCAS-PER-059: “Norton Company”

Effective Date: 4/24/2015

No TBD exists for Norton Company. However, a 

“DR Methodology Template” was used for 

completing claims, which has been modified.

Changes to the template include the addition 

of a class of employees to the SEC based on 

NIOSH’s inability to estimate internal and 

external dose between 1/1/1945 and 

10/10/1962. Also, contamination depletion 

rates changed during the residual period 

starting 10/10/1962, causing an increase in 

dose.

54 initially identified cases.

43 cases remained after 

removing claim that had 

employment only prior to 

1962.

SC&A recommends that the 

PER be reviewed, since the 

DR methodology used in the 

template has not been 

previously evaluated by the 

Board.

PER Description Doses Changes Cases Impacted SC&A’s Recommendation

DCAS-PER-060: “Blockson Chemical Company”

Effective Date: 4/27/2015

Revision 4 of the Blockson TBD changed the way 

internal dose was estimated for the stomach, small 

intestine, upper large intestine, lower large 

intestine, and colon.

The TBD revision changes instruction to 

comparison ingestion and inhalation doses 

and assign the dose that produces the higher 

dose.

23 cases initially identified.

6 cases remained after 

considering cases 

compensated under the SEC 

and one cases that had been 

completed using Rev. 4.

SC&A recommends that

there is no need to complete 

Subtasks 1–3 of SC&A’s 

PER review procedure since 

this PER was initiated due to 

findings from a previously 

reviewed Blockson TBD 

PER (PER-036). However, 

SC&A does recommend a 

review of 1 or 2 claims 

under Subtask 4 of our 

procedure.

OCAS-PER-061: “Bridgeport Brass Company”

Effective Date: 6/5/2015

The TBD covers operations at the Bridgeport Brass 

Havens Laboratory in Bridgeport, CT as well as 

the Adrian Facility in Adrian, MI. This revision 

(Rev. 2) was issued due to a change in the facility 

designation for the Adrian Facility by the U.S. 

Department of Labor (DOL).

Primary changes include (1) external dose 

was analyzed using OTIB-0020 in Rev. 1 of 

the TBD and using a Monte Carlo approach 

in Rev. 0; and (2) thorium intakes in Rev. 1 

were assigned based on air samples and, in 

Rev. 0, thorium intakes were assigned as a 

fraction of the uranium intake.

14 cases identified at 

Haven’s Lab; 36 cases at 

Adrian Facility. All 50 cases

were reevaluated.

SC&A recommends that this 

PER be reviewed, since the 

only review of these 

facilities has been performed 

under an expanded review of

a DR audit performed in 

May 2008.

DCAS-PER-063: “Aluminum Company of 

America – Pennsylvania (ALCOA-PN)”

Effective Date: 6/15/2015

DRs are performed using Appendix R of BattelleTBD-6000. Revision 1 of TBD-6000 was issued to 

incorporate OTIB-0070 and other changes.

Revision 1 increased inhalation, ingestion, 

and external photon dose during the 

operation period.

44 cases initially identified.

35 cases were reevaluated.

SC&A recommends that this 

PER be reviewed, since the 

Board has not previously

evaluated the ALCOA-PN 

DR methodology.

PER Description Doses Changes Cases Impacted SC&A’s Recommendation

DCAS-PER-064: “DuPont Deep Water Work”

Effective Date: 11/16/2015

DRs were originally performed using Appendix B 

of Battellee-TBD-6001. TBD-6001 was cancelled 

and the Appendix converted to a standalone TBD 

(DCAS-TKBS-0006). This PER evaluates changes 

introduced in Revision 2 of the TBD.

Inhalation intakes and external dose rates 

increased during the operational period and 

ingestion intakes increased during the 

residual period. 

56 cases were identified and 

reevaluated.

Since SC&A has reviewed 

revision 1 of Appendix B, 

there is no need to complete 

Subtasks 1–3 of SC&A’s 

PER review procedure. 

However, SC&A does 

recommend a review of a 

number of representative 

claims under Subtask 4 of 

our procedure. If tasked with 

the Subtask 4 review, SC&A 

will (1) provide case 

selection criteria, (2) identify 

relevant cases, and (3) 

perform a review of selected 

reworked claims.

DCAS-PER-065: “Anaconda”

Effective Date: 11/30/2015

DRs are performed using Appendix G of BattelleTBD-6000. Revision 1 of TBD-6000 was issued to 

incorporate changes to TBD-6000 and to make 

dose estimates more consistent with existing 

techniques.

External photon doses increased for all job 

categories in all years of operations.

10 cases identified and 

reevaluated.

SC&A recommends that this 

PER be reviewed, since the 

Board has not previously 

evaluated the Anaconda DR 

methodology.

PER Description Doses Changes Cases Impacted SC&A’s Recommendation

DCAS-PER-066: “Huntington Pilot Plant”

Effective Date: 11/30/2015

This PER evaluates changes to Rev. 1 of DCASTKBS-0004.

Revision 1 added intakes for Am-241, 

thorium-230 (Th-230), and technetium-99 

(Tc-99) and, therefore, increased internal 

dose estimates for cases.

59 cases initially identified.

57 cases required a new dose 

estimate.

Since SC&A has reviewed 

Revision 0 of DCAS-TKBS0004, there is no need to 

complete Subtasks 1–3 of 

SC&A’s PER review 

procedure. However, SC&A 

does recommend a review of 

a number of representative 

claims under Subtask 4 of 

our procedure. If tasked with 

the Subtask 4 review, SC&A 

will (1) provide case 

selection criteria, (2) identify 

relevant cases, and (3) 

perform a review of selected 

reworked claims.

 Corrects a footnote in Table 4-24 (the year 1947 superscript was changed 

from i to j). 

 Changes made to Section 6.4 regarding tunnel occupancy time. 

 Previously, the text assumed that Trade Workers and Laborers wor

tunnels doing maintenance for 8 hours per workday (hr/wd) (2 mon

the year) and for the other 10 months, spent a transit time of 10 mi

per workday (min/wd) using the tunnels to get between buildings. 

other workers, the assumption that only the transit time of 10 min/

should be applied year-round was changed to, for Trade Workers 

Laborers, the assumption that they worked in these tunnels doing 

maintenance 50% of their time. For all other workers, an occupanc

of 5% was assumed. This change did not affect Table 6-12 values.

ORAUT-OTIB-0064: Coworker External Dosimetry 

Data for the Y-12 National Security Complex -

Revision: 02 

Effective Date: 04/29/2013 

Supersedes: ORAUT-OTIB-0047, Revision 00 and 

Revision 01

Technical information bulletin initially approved 08/03/2009 for providing 

background information on the Y-12 coworker external dosimetry data, which 

includes tables with annual values that may be used in the process of assigning 

doses for unmonitored years of employment. 

Revision 1was issued 12/18/2009 to modify Sections 4.0 and 5.0 to be 

consistent with current practices of applying coworker data. Table 7-1c and 

references to Tables 7-1a, 7-1b, and 7-1c were added in Section 7.0. Table 7-1c 

includes the 95th- and 50th-percentile annual doses derived from Table 7-1a. 

Adds details for Table 7-1c in Section 7.0. In Section 7.0, Table 7-2 was 

updated to include 1947 to 1949.

Revision 02 was published 04/29/2013 to update Section 6.1 and add update of 

previous ORAUT-OTIB-0047, Revision 00 as Attachment A.

This OTIB also contains guidance previously cited in ORAUT-PROC-0042

(Account for Incomplete Personal Monitoring Data on Penetrating Gamma-Ray 

Doses), which has been canceled.
