Federal Register / Vol. 74, No. 109 / Tuesday, June 9, 2009 / Notices 27313 

Burden Statement: The annual public 

reporting and recordkeeping burden for 

this collection of information is 

estimated to average 1.9 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. 

The ICR supporting statement 

provides a detailed explanation of the 

Agency’s estimate, which is only briefly 

summarized here: 

Estimated total number of potential 

respondents: 1,694 (1,638 public water 

systems and 56 State primacy agencies). 

Frequency of response: 1 response per 

year. 

Estimated total average number of 

responses for each respondent: 3. 

Estimated total annual burden hours: 

9,761. 

Estimated average number of burden 

hours per response: 1.9. 

Estimated total annual costs: 

$3,250,616. This includes an estimated 

burden cost of $387,096 and an 

estimated cost of $2,863,520 for 

analytical costs. 

Small systems (those serving 10,000 

or fewer) that are selected for UCMR 2 

monitoring will sample an average of 

2.7 times per system (i.e., number of 

responses per system) across the threeyear ICR renewal period of 2010–2012. 

The average total burden per response 

for small systems is estimated to be 1.8 

hours. Large systems (those serving 

10,001 to 100,000) and very large 

systems (those serving more than 

100,000) will sample and report an 

average of 3.1 and 3.6 times per system, 

respectively, across the three-year ICR 

period of 2010–2012. The average total 

burdens per response for large and very 

large systems are estimated to be 3.8 and 

8.7 hours, respectively. The larger 

burden per response for the very large 

systems reflects the fact that these 

systems typically have more sampling 

locations than large systems. States are 

assumed to incur 2 responses over the 

three-year ICR period related to 

coordination with EPA and systems, 

with an average burden per response of 

95.2 hours. In aggregate, during the ICR 

period of 2010–2012, the average 

response (e.g., responses from systems 

and States) is associated with a total 

burden of 5.8 hours, with a labor plus 

non-labor cost of $1,939 per response. 

The annual average per respondent 

burden hours and costs for the ICR 

period of 2010–2012 are: small 

systems—1.6 hour burden at $44 for 

labor; large systems—3.8 hours at $114 

for labor, and $1,747 for analytical costs; 

very large systems—10.4 hours at $369 

for labor, and $7,260 for analytical costs; 

and States—63.5 hours at $3,499 for 

labor. Annual average burden and cost 

per respondent (including both systems 

and States) is estimated to be 5.8 hours, 

with a labor plus non-labor cost of 

$1,919 per respondent (note that small 

systems do not pay for testing costs, so 

they only incur labor costs). The total 

annual burden for the ICR reporting 

period of 2010–2012 is 9,761 hours 

(with a labor cost of $387,096); the total 

annual analytical cost is $2.86 million. 

Are There Changes in the Estimates 

From the Last Approval? 

The renewal of this ICR will result in 

an overall decrease of 91,875 hours in 

the total estimated respondent burden 

identified in the currently approved ICR 

(OMB Control No. 2040–0270). The 

complete five-year UCMR 2 cycle of 

2007–2011 overlaps with the applicable 

ICR renewal period only during 2010 

and 2011. Moreover, public water 

systems will only be involved in active 

monitoring during 2010 (i.e., one-third 

of this ICR period). Thus, the reasons 

that respondents to UCMR 2 will incur 

a different burden during this second 

ICR period of 2010–2012, than during 

the first UCMR 2 ICR period of 2007– 

2009 include: 

• Fewer PWSs participating during 

this ICR period: UCMR 2 monitoring 

takes place from 2008–2010, with 

approximately 1⁄3 of systems 

participating in each of those three 

years. Thus, during the first ICR period 

of 2007–2009, approximately 2⁄3 of 

participating systems (~ 3,275 systems) 

have completed their required 

monitoring, and during the second ICR 

period of 2010–2012, the remaining 1⁄3

(~ 1,638 systems) will complete their 

required monitoring. 

• Schedule of activities for PWSs 

different during this ICR period: Some 

initial activities were conducted by all 

systems during 2007 (or prior to 

monitoring), including reading 

regulations, and reporting prior to 

monitoring (contact and sampling 

location information, and proposals to 

reduce the number of required 

monitoring locations). Thus, there are 

some PWS activities that took place 

during the first UCMR 2 ICR period of 

2007–2009, that will not take place 

during the second ICR period of 2010– 

2012. 

• Schedule of activities also different 

for participating States and EPA: 

Management and support activities for 

States and EPA also vary with the 

UCMR 2 monitoring schedule. Thus, 

both States and EPA are expected to 

have different burdens during this 

second UCMR 2 ICR period of 2010– 

2012. 

What Is the Next Step in the Process for 

This ICR? 

EPA will consider the comments 

received and amend the ICR as 

appropriate. The final ICR package will 

then be submitted to OMB for review 

and approval pursuant to 5 CFR 

1320.12. At that time, EPA will issue 

another Federal Register notice 

pursuant to 5 CFR 1320.5(a)(1)(iv) to 

announce the submission of the ICR to 

OMB and the opportunity to submit 

additional comments to OMB. If you 

have any questions about this ICR or the 

approval process, please contact the 

technical person listed under FOR

SUPPLEMENTARY INFORMATION: 

I. Summary of Information About the 

Integrated Risk Information System 

(IRIS) 

IRIS is a database that contains 

potential adverse human health effects 

information that may result from 

chronic (or lifetime) exposure to specific 

chemical substances found in the 

environment. The database (available on 

the Internet at http://www.epa.gov/iris) 

contains qualitative and quantitative 

health effects information for more than 

540 chemical substances that may be 

used to support the first two steps 

(hazard identification and doseresponse evaluation) of a risk 

assessment process. When supported by 

available data, the database provides 

oral reference doses (RfDs) and 

inhalation reference concentrations 

(RfCs) for chronic health effects, and 

oral slope factors and inhalation unit 

risks for carcinogenic effects. Combined 

with the specific exposure information, 

government and private entities can use 

IRIS data 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. 

II. Listening Session Information 

The purpose of the listening session is 

to allow all interested parties to present 

scientific and technical comments on 

draft IRIS health assessments to EPA 

and other interested parties during the 

public comment period and prior to the 

external peer review workshop. EPA 

welcomes the scientific and technical 

comments that will be provided to the 

Agency by the listening session 

participants. The comments will be 

considered by the Agency as it revises 

the draft assessment in response to the 

independent external peer review and 

public comments. All presentations will 

become part of the official and public 

record. 

III. Workshop Information 

Members of the public may attend the 

workshop as observers, and there will 

be a limited time for oral comments 

from the public. Pre-registration is 

strongly recommended as space is 

limited, and registrations will be 

accepted on a first-come, first-served 

basis. The deadline for pre-registration 

is August 10, 2009. If space allows, 

registrations will continue to be 

accepted after this date, including onsite registrations. Time will be set aside 

to hear comments from observers, and 

individuals will be limited to a 

maximum of five minutes. Please let 

Versar, Inc. know if you wish to make 

comments during the workshop by 

registering as detailed in this FR notice 

and indicating your intent to make oral 

comments.
