policies affecting future labeling of 

insect repellents. The ultimate goal of 

this activity is to help the consumer to 

effectively use the information on the 

label to select the insect repellent 

product most likely to meet their needs 

and readily understand label 

instructions regarding safe product use. 

Responses to this collection of 

information are voluntary. One survey 

would be conducted over the life of this 

ICR. The collected information could be 

used to revise insect repellent product 

labels and to create other user friendly 

consumer information materials. By 

enabling consumers to make better 

choices in regard to purchasing and 

using products intended to protect their 

health, EPA will more effectively carry 

out its mandate to protect the public 

from unreasonable risks to human 

health. 

Burden Statement: The annual public 

reporting and recordkeeping burden for 

this collection of information is 

estimated to average 15 minutes per 

response. Burden is defined in 5 CFR 

1320.3(b). 

Respondents/Affected Entities: 

members of the general public would 

participate in the survey. 

Estimated Number of Potential 

Respondents: 3000. 

Frequency of Response: One time. 

Estimated Total Annual Hour Burden: 

750 hours. 

Estimated Total Annual Cost: 

$15,675. 

Changes in the Estimates: This is a 

new collection.

Notice of Availability of the External 

Review Draft of the Guidance for 

Applying Quantitative Data To Develop 

Data-Derived Extrapolation Factors for 

Interspecies and Intraspecies 

Extrapolation 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice of document availability 

for public comment. 

SUMMARY: The Environmental Protection 

Agency (EPA) is announcing a 45-day 

public comment period for the External 

Review Draft of ‘‘Guidance for Applying 

Quantitative Data to Develop DataDerived Extrapolation Factors for 

Interspecies and Intraspecies 

Extrapolation.’’ EPA is releasing this 

draft document solely for the purpose of 

seeking public comment prior to 

external peer review. The document 

will undergo independent peer review 

during an expert peer review meeting, 

which will be convened, organized, and 

conducted by an EPA contractor in 

2011. The date of the external peer 

review meeting will be announced in a 

subsequent Federal Register notice. All 

comments received by the docket 

closing date July 25, 2011 will be shared 

with the external peer review panel for 

their consideration. Comments received 

after the close of the comment period 

may be considered by EPA when it 

finalizes the document. This document 

has not been formally disseminated by 

EPA. This draft guidance does not 

represent and should not be construed 

to represent EPA policy, viewpoint, or 

determination. Members of the public 

may obtain the draft interim guidance 

from http://www.regulations.gov; or 

http://www.epa.gov/raf/DDEF/ 

index.htm or from Dr. Michael Broder 

via the contact information below. 

This draft Guidance for Data Derived 

Extrapolation Factors document 

outlines approaches for developing 

factors for inter- and intra-species 

extrapolation based on data describing 

toxicokinetic and/or toxicodynamic 

properties of particular agent(s). The 

draft document was developed to 

provide guidance for EPA staff in 

evaluating such data and/or information 

and to provide information to the 

regulated community and other 

interested parties about deriving and 

implementing extrapolation factors 

derived from data instead of defaults. 

DATES: All comments received by the 

docket closing date July 25, 2011 will be 

shared with the external peer review 

panel for their consideration. Comments 

received beyond that time may be 

considered by EPA when it finalizes the 

document.

SUPPLEMENTARY INFORMATION: Key goals 

for the U.S. EPA include improving the 

transparency, objectivity and scientific 

basis for health risk assessment. In 2005, 

a WHO-sponsored effort produced 

guidance on the development of 

Chemical-Specific Adjustment Factors 

(CSAFs). CSAFs are intended to replace 

default uncertainty factor values for 

inter- and intraspecies extrapolation in 

health risk assessment. The U.S. EPA 

recognizes differences between the 

WHO guidance and typical Agency risk 

assessment practices, policies and 

guidance. EPA’s Risk Assessment 

Forum convened a technical panel that 

initiated work on developing draft 

guidance for use in replacing default 

values for inter- and intraspecies 

uncertainty factors with science-based 

extrapolation factors. The draft 

document has been reviewed by EPA’s 

Risk Assessment Forum and Science 

and Technology Policy Council and 

approved for external review. In 2010, 

the document was sent to the National 

Science and Technology Council 

(NSTC) Committee on Environment and 

Natural Resources, Toxics and Risk 

Subcommittee for informal review and 

comment. The draft document is now 

available for public comment. 

The draft document has been 

structured and developed in accordance 

with existing Agency policies on health 

risk assessment. The draft document 

provides guidance for the evaluation of 

data describing interspecies differences 

in chemical disposition (toxicokinetics); 

interspecies differences in toxicantinduced response (toxicodynamics); 

intraspecies differences in chemical 

disposition (toxicokinetics); and 

intraspecies differences in toxicantinduced response (toxicodynamics). The 

document maintains the subdivision of 

the interspecies and intraspecies 

uncertainty factors into toxicokinetic 

and toxicodynamic components 

specified in the U.S. EPA Inhalation 

Reference Concentration methodology 

(U.S. EPA, 1994). EPA will consider all 

peer review and public comments in 

finalizing Guidance for Applying 

Quantitative Data to Develop DataDerived Extrapolation Factors for 

Interspecies and Intraspecies 

Extrapolation.

Modification of the Expiration Date for 

the National Pollutant Discharge 

Elimination System General Permit for 

Stormwater Discharges From 

Construction Activities on Tribal Lands 

Within the Southeastern United States 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice. 

SUMMARY: EPA Region 4 proposes to 

modify the expiration date of the 

National Pollutant Discharge 

Elimination System (NPDES) general 

permit authorizing the discharge of 

stormwater from construction activities 

on Tribal Lands within the states of 

Alabama, Florida, Mississippi and 

North Carolina. This NPDES 

construction general permit (CGP), 

hereinafter referred to as ‘‘the Region 4 

CGP,’’ was issued on September 1, 2009, 

with an expiration date of August 31, 

2011. EPA Region 4 is proposing to 

extend the expiration date from August 

31, 2011, to September 1, 2012. No other 

revisions are being proposed to the 

Region 4 CGP. The purpose of extending 

the expiration date is to ensure that 

there is no lapse in permit coverage 

prior to the effective date of the issuance 

of a new permit, which has been 

proposed for public review and 

comment in a separate action. 

Information about the proposed new 

permit, hereinafter referred to as ‘‘the 

new National CGP,’’ can be found at 

http://cfpub.epa.gov/npdes/stormwater/ 

cgp.cfm. 

DATES: EPA is proposing a modification 

to the Region 4 CGP that would extend 

the expiration date from August 31, 

2011, to September 1, 2012. If the 

proposed modification is finalized, the 

Region 4 CGP would expire at midnight, 

on September 1, 2012, or on the 

effective date of the new National CGP, 

whichever is earlier. Comments on the 

proposal to modify the expiration date 

of the Region 4 CGP must be 

postmarked by July 11, 2011.
