system is inoperative. Reports, at a 

minimum, are required semiannually. 

Burden Statement: The annual public 

reporting and recordkeeping burden for 

this collection of information is 

estimated to average 34 hours per 

response. Burden means the total time, 

effort, or financial resources expended 

by persons to generate, maintain, retain, 

or disclose or provide information to or 

for a Federal agency. This includes the 

time needed to review instructions; 

develop, acquire, install, and utilize 

technology and systems for the purposes 

of collecting, validating, and verifying 

information, processing and 

maintaining information, and disclosing 

and providing information; adjust the 

existing ways to comply with any 

previously applicable instructions and 

requirements which have subsequently 

changed; train personnel to be able to 

respond to a collection of information; 

search data sources; complete and 

review the collection of information; 

and transmit or otherwise disclose the 

information. 

Respondents/Affected Entities: 

Synthetic fiber production facilities. 

Estimated Number of Respondents: 

22. 

Frequency of Response: Initially, 

occasionally, quarterly, and 

semiannually. 

Estimated Total Annual Hour Burden: 

1,859. 

Estimated Total Annual Cost: 

$315,119, which includes $150,119 in 

labor costs, no annualized capital/ 

startup costs and operation and 

maintenance (O&M) costs of $165,000. 

Changes in the Estimates: There is no 

change in the labor hours or cost to the 

respondents in this ICR compared to the 

previous ICR. This is due to two 

considerations. First, the regulations 

have not changed over the past three 

years and are not anticipated to change 

over the next three years. Secondly, the 

growth rate for respondents is very low, 

negative, or non-existent. Therefore, the 

labor hours and cost figures in the 

previous ICR reflect the current burden 

to the respondents and are reiterated in 

this ICR.

Integrated Risk Information System 

(IRIS) Update Project; Announcement 

of 2009/2010 Agenda 

AGENCY: Environmental Protection 

Agency. 

ACTION: Notice of 2009/2010 IRIS 

Update Project and request for 

information. 

SUMMARY: The U.S. Environmental 

Protection Agency (EPA) is announcing 

the establishment of the Integrated Risk 

Information System (IRIS) Update 

Project. The purpose of the IRIS Update 

Project is to revisit a portion of the doseresponse assessment values with a 

posting date on the IRIS database that is 

more than 10 years old. IRIS is an EPA 

data base containing human health risk 

information on possible adverse health 

effects that may result from chronic or 

long-term exposures to chemical 

substances found in the environment. 

This Federal Register notice (FRN) also 

announces the IRIS Update Project’s 

2009/2010 agenda and requests 

submission of new and relevant 

scientific information on health effects 

for the identified assessments listed in 

the Project’s 2009/2010 agenda. 

While EPA is not expressly soliciting 

comments on this notice, the Agency 

will accept information related to the 

substances included herein. Please

SUPPLEMENTARY INFORMATION: 

Background 

The intent of the IRIS Update Project 

is to revisit all dose-response 

assessment toxicity values such as oral 

reference doses (RfDs), inhalation 

reference concentrations (RfCs), cancer 

oral slope factors, and cancer inhalation 

unit risks in IRIS with a posting or entry 

date more than 10 years old. 

IRIS is a database of human health 

effects that may result from chronic 

exposure to various chemical substances 

or other contaminants found in the 

environment. IRIS currently provides 

information on health effects associated 

with more than 500 chemical 

substances. The database includes 

substance-specific summaries of 

qualitative and quantitative health 

information in support of the first two 

steps of the risk assessment process, i.e., 

hazard identification and dose-response 

evaluation. Also, IRIS has included 

detailed Toxicological Reviews as 

support documents since 1995. 

Government and private entities use 

IRIS, combined with specific exposure 

information, to help characterize public 

health risks of chemical substances in a 

site-specific situation and thereby 

support risk management decisions 

designed to protect public health. IRIS 

is prepared and maintained by the 

EPA’s National Center for 

Environmental Assessment within the 

Office of Research and Development. 

While separate from the regular IRIS 

program, the IRIS Update Project draws 

on the IRIS data base as the source of 

human health assessments in need of 

update. The purpose of the IRIS Update 

Project is to replace existing IRIS 

assessment toxicity values and their 

supporting information that are more 

than 10 years old with new and relevant 

scientific information on health effects. 

As updated assessments are completed 

as part of this process, they will be 

posted on IRIS. 

The IRIS Update Project defines 

‘‘assessment’’ as an individual IRIS 

toxicity value along with its supporting 

information. For example, the Project 

identifies the values for an oral RfD, an 

inhalation RfC, and a cancer evaluation 

along with supporting information, as 

three assessments. Certain IRIS entries, 

however, may contain values that do not 

qualify for the update process. For 

example, a particular substance with an 

oral RfD derived 15 years ago would 

qualify for the update process, but a 


jlentini on DSKJ8SOYB1PROD with NOTICES
Federal Register / Vol. 74, No. 202 / Wednesday, October 21, 2009 / Notices 54041 

cancer evaluation derived 3 years ago 

for that same substance would not 

qualify. Also, the IRIS Update Project 

will not address any substances or 

toxicity values that are not currently on 

IRIS. 

The IRIS Update Project’s process 

consists of: (1) Publishing an annual 

Federal Register notice announcing 

EPA’s IRIS Update Project agenda and 

calling for scientific information from 

the public regarding assessments on the 

agenda; (2) conducting a comprehensive 

search of the current scientific literature 

on each assessment; (3) developing draft 

health assessment documents using 

state of the science methods and 

guidelines; (4) conducting a combined 

simultaneous review of the draft 

assessment documents by EPA and 

other Federal Agencies via the Federal 

Standing Science Committee; (5) 

soliciting public comments on draft 

assessments, followed by independent 

external peer review under the Federal 

Advisory Committee Act (FACA); (6) 

preparing final IRIS assessments that 

reflect public comments and 

independent expert review; and (7) 

replacing the existing assessments with 

the final updated IRIS assessments on 

the IRIS data base (http://www.epa.gov/ 

iris). 

This FRN describes only the first two 

steps of the update process. The 

literature and new data obtained in 

response to this FRN will be evaluated 

as to whether or not the assessment(s) 

can be completed within the resources 

and capacity of the IRIS Update Project. 

A subsequent FRN will announce the 

assessments proceeding through steps 3 

through 6. 

IRIS Update Agenda 

Each year, EPA will develop a priority 

list of chemicals and an agenda of 

assessments to undergo the IRIS update 

process. EPA uses a variety of criteria to 

prioritize which assessments will be 

included on the agenda. General priority 

criteria include: Consideration of 

potential public health impact; EPA 

statutory, regulatory, or programspecific implementation needs; interest 

to other governmental agencies or the 

public; and availability of other 

scientific assessment documents that 

could serve as a basis for an update of 

an IRIS assessment. Specific priority 

criteria will take into consideration the 

frequency of occurrence in National 

Priority List (NPL) waste sites, 

occurrence as hazardous air pollutants 

used in residual risk assessments, and 

potential as a water pollutant based on 

the chemical contaminants list (CCL). 

The Update Project will strive to 

prevent duplication of effort with other 

assessment organizations. Thus, 

assessments currently on IRIS Track or 

assessments for pesticides that are 

available elsewhere within EPA have 

been eliminated from consideration for 

the IRIS Update Project. 

EPA is soliciting public involvement 

in the process for those assessments on 

the IRIS Update Project’s 2009/2010 

agenda. While EPA conducts a thorough 

literature search for each assessment, 

there may be unpublished studies or 

other primary technical sources that are 

not available through the open 

literature. EPA would appreciate 

receiving scientific information from the 

public during the information gathering 

stage for the assessments listed in this 

notice. Interested persons should 

provide scientific analyses, studies, and 

other pertinent scientific information. 

This notice provides instructions for 

submitting scientific information to EPA 

pertinent to updating these assessments.

Information Requested on IRIS Update 

Assessments for 2009/2010 

EPA is currently conducting literature 

searches for these assessments. The 

overall purpose of these literature 

searches is to identify new and relevant 

information for each assessment. 

Relevant information is that which 

improves the scientific understanding of 

the agent’s toxicity in humans; new 

information is relevant information that 

is not included in the current online 

IRIS assessment. Based on the results of 

the literature searches and the 

information submitted in response to 

this announcement, EPA will evaluate 

assessments to determine whether they 

can be accommodated within the scope 

and resources of the IRIS Update 

Project. 

With this IRIS update agenda 

announcement, EPA is actively 

soliciting information from the public at 

the beginning of the assessment update 

process. As literature searches are 

completed, they will be posted at 

http://www.regulations.gov for public 

inspection.
