Draft Toxicological Review of 1,4-Dioxane: In Support of the Summary Information in the Integrated Risk Information System (IRIS), 27313-27315 [E9-13478]

Download as PDF Federal Register / Vol. 74, No. 109 / Tuesday, June 9, 2009 / Notices 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 VerDate Nov<24>2008 14:45 Jun 08, 2009 Jkt 217001 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 PO 00000 Frm 00038 Fmt 4703 Sfmt 4703 27313 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 FURTHER INFORMATION CONTACT. Dated: June 1, 2009. Cynthia C. Dougherty, Director, Office of Ground Water and Drinking Water. [FR Doc.

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 https://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 dose-response 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 
on-site 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.
