NUCLEAR REGULATORY 

COMMISSION 

[NRC–2015–0044] 

Guidance for Evaluation of Acute 

Chemical Exposures and Proposed 

Quantitative Standards 

AGENCY: Nuclear Regulatory 

Commission. 

ACTION: Draft interim staff guidance; 

supplemental information; extension of 

comment period. 

SUMMARY: The U.S. Nuclear Regulatory 

Commission (NRC) is providing 

supplemental information to an earlier 

notice, appearing in the Federal 

Register on March 4, 2015, which 

requested comment on a draft interim 

staff guidance (ISG), ‘‘Guidance for 

Evaluation of Acute Chemical 

Exposures and Proposed Quantitative 

Standards.’’ The draft ISG, if issued in 

final form, would supplement existing 

guidance in NUREG–1520, ‘‘Standard 

Review Plan for the Review of a License 

Application for a Fuel Cycle Facility,’’ 

by providing additional guidance and 

the descriptions of proposed 

quantitative standards for the NRC to 

follow when evaluating the integrated 

safety analysis (ISAs) of acute chemical 

exposures. This action is necessary to 

provide the public with the backfitting 

information with respect to the draft 

ISG, and includes references to the key 

documents on backfitting issues. The 

public comment period was originally 

scheduled to close on May 18, 2015. 

The NRC is extending the public 

comment period on this action to allow 

more time for members of the public to 

review the additional information on 

backfitting before submitting any 

comments. 

DATES: The due date of comments 

requested in the document published on 

March 4, 2015 (80 FR 11692) is 

extended. Comments should be filed no 

later than July 1, 2015. Comments 

received after this date will be 

considered if it is practical to do so, but 

the Commission is able to ensure 

consideration only for comments 

received before this date. 

ADDRESSES: You may submit comments 

by any of the following methods (unless 

this document describes a different 

method for submitting comments on a 

specific subject):

II. Background 

The NRC is providing supplemental 

information to a notice requesting 

comment on its draft ISG, ‘‘Guidance for 

Evaluation of Acute Chemical 

Exposures and Proposed Quantitative 

Standards,’’ that was published in the 

Federal Register (80 FR 11692; March 4, 

2015). The draft ISG, if issued in final 

form, would supplement existing 

guidance in NUREG–1520, ‘‘Standard 

Review Plan for the Review of a License 

Application for a Fuel Cycle Facility’’ 

(ADAMS Accession No. ML101390110), 

by providing additional guidance for the 

NRC to follow when evaluating the ISAs 

of acute chemical exposures, including 

the descriptions of proposed 

quantitative standards used to classify 

exposure events using the general 

criteria of section 70.61 of title 10 of the 

Code of Federal Regulations (10 CFR). 

The draft ISG identifies sources of 

information that the staff could use 

when reviewing the proposed 

quantitative standards. 

This supplemental information 

provides the NRC’s proposed position 

on backfitting with respect to the draft 

ISG, and includes references to the key 

documents on backfitting. The public 

comment period was originally 

scheduled to close on May 18, 2015. 

The NRC has decided to extend the 

public comment period on the draft ISG 

to allow more time for members of the 

public to review the supplemental 

information before submitting any 

comments. 

III. Supplemental Information 

The NRC believes that the draft ISG, 

if issued in final form, would not 

constitute backfitting as defined in 10 

CFR 70.76(a)(1). All fuel cycle facility 

licensees are required to conduct and 

maintain an ISA that analyzes the 

chemical hazards of licensed material. 

The performance requirements in 10 

CFR 70.61(b) and (c) require that the 

risk of each credible high or 

intermediate consequence event be 

limited, and such events include those 

arising from an acute chemical exposure 

as specified in 10 CFR 70.61(b)(4) and 

(c)(4). For all credible event 

consequences as specified in 10 CFR 

70.61(b)(4) and (c)(4), the ISA summary 

must describe the proposed quantitative 

standards used to address acute 

chemical exposures from credible event 

sequences in accordance with 10 CFR 

70.65(b)(7). This requirement is 

reinforced by the ISA definition in 10 

CFR 70.4. Subpart H of 10 CFR part 70 

contains performance-based 

requirements under which the 

applicant/licensee must address all 

credible hazards, and there is no 

regulatory language limiting 

consideration of chemical hazards to 

specific exposure pathways. The draft 

ISG is consistent with the regulatory 

language in subpart H of 10 CFR part 70 

and the NRC’s position that the ISA 

should consider all acute chemical 

exposures, including dermal and ocular 

exposures. 

Since the initial NRC approval of ISA 

summaries, there have been a number of 

hazardous chemical exposure incidents 

involving dermal and ocular exposures 

at fuel cycle facilities. Two of these 

incidents of exposure have resulted in 

intermediate or high consequences. See 

Table 1, Fuel Cycle Facility Dermal and 

Ocular Exposure Events Known to the 

NRC Staff. The NRC believes that these 

events demonstrate the need for fuel 

cycle facilities to address all exposure 

pathways when updating their safety 

programs, ISAs, and ISA summaries. 

The information contained in the draft 

ISG reflects and reiterates existing NRC 

regulatory requirements for the fuel 

cycle facility licensees who will be 

subject to the draft ISG. Therefore, 

issuance of the draft ISG in final form 

would not constitute backfitting. The 

NRC’s positions on backfitting with 

respect to consideration of all exposure 

pathways (the subject of this draft ISG) 

are set forth in a September 15, 2014, 

letter to the Nuclear Energy Institute 

(NEI) (ADAMS Accession No. 

ML14251A150; Enclosure: ADAMS 

Accession No. ML14251A149). The 

NRC’s September 2014 letter responds 

to a March 26, 2014, letter from NEI to 

the NRC (ADAMS Accession No. 

ML14086A267), which raises backfitting 

issues with respect to consideration of 

dermal and ocular exposures to 

hazardous chemicals at NRC-regulated 

fuel cycle facilities. The NEI also 

provided their views on backfitting with 

respect to consideration of dermal and 

ocular exposures to hazardous 

chemicals at NRC-regulated fuel cycle 

facilities in a November 7, 2014, letter 

to the General Counsel of the NRC 

(ADAMS Accession No. ML14322B019).

Date Event Description (drawn from NMED text) 

1. 12/3/1992 Employee sprayed with an acid/uranium mixture 

2. 1/27/1998 UF6 release, three workers received minor HF acid burns on necks and arms 

(NRC Event Notification (EN) 33601) 

3. 8/10/2001 UF6 release, two workers treated for HF acid burns (EN38198)

exposure" (NRC Press Release [ADAMS Accession No. ML061170441] 

1 Table 1 presents all events involving chemical exposures at fuel cycle facilities known to the 

NRC staff based upon staff review of the Nuclear Medical Events Database (NMED). There may 

be additional events not included in this Table. This Table includes some chemical exposure 

events which were not classified as intermediate or high consequence, because small changes in 

scenario (e.g., location of the worker relative to the spill/release, magnitude of the spill/release, 

how fast a worker can exit an area, timeliness and nature of first aid) can change the 

classification of the severity of an event (classified in accordance with the 10 CFR 70.61 criteria). 

2 This event may be classified as intermediate or high consequence, and was the subject of NRC 

Information Notice (IN) 2007-022 (ADAMS Accession No. ML071410230). Another chemical 

exposure event was identified in IN 2007-022, but is not included in this Table because the event 

involved an inhalation exposure.
