This site displays a prototype of a “Web 2.0” version of the daily Federal Register. It is not an official legal edition of the Federal Register, and does not replace the official print version or the official electronic version on GPO’s govinfo.gov.
The documents posted on this site are XML renditions of published Federal Register documents. Each document posted on the site includes a link to the corresponding official PDF file on govinfo.gov. This prototype edition of the daily Federal Register on FederalRegister.gov will remain an unofficial informational resource until the Administrative Committee of the Federal Register (ACFR) issues a regulation granting it official legal status.

The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.

Notice of Peer Consultation Workshop on the Cumulative Mixtures Risk of Six Selected Phthalates; Request for Public Comments.
EPA is announcing that ICF International, an EPA contractor for external scientific peer consultation, will convene a panel of independent experts and conduct an external peer consultation workshop to: (1) Review the recommendations for evaluation of the cumulative mixtures risk of phthalates as set forth in the National Academies of Science (NAS) report “Phthalates and Cumulative Risk Assessment: The Tasks Ahead” (2008); and (2) propose additional methods and Start Printed Page 69663approaches, not already captured in the 2008 NAS report, that may facilitate the assessment of risk(s) associated with exposure to cumulative mixtures of the six selected phthalates.
ICF International invites all interested public parties to register to attend this workshop as observers. Space is limited, and reservations will be accepted on a first-come, first-served basis. In addition, ICF International invites the public to give brief oral comments at the conclusion of each workshop day. Furthermore, there is an opportunity to provide written comments regarding the subject matter under discussion; for more information please see below. In conceptualizing and preparing a draft of the “Toxicological Review of the Cumulative Mixtures Risk of Six Selected Phthalates,” EPA will consider ICF's report of the comments and recommendations from individuals participating in the external peer consultation workshop and any written public comments that EPA receives in accordance with this notice.
The peer consultation workshop on the Cumulative Mixtures Risk of Six Selected Phthalates will be held on December 8 and 9, 2010, beginning at 8 a.m. and ending at 5 p.m. Eastern Standard Time. Please note that a public comment period begins November 15, 2010 and ends January 4, 2011. Technical comments should be in writing and must be received by the EPA by January 4, 2011.
The peer consultation workshop on the Cumulative Mixtures Risk of Six Selected Phthalates will be held at the Double Tree Crystal City, located at 300 Army Navy Drive in Arlington, VA. To attend the workshop, register no later than December 3, 2010, preferably via the workshop Web site page at http://epa.phthalatesworkshop.icfi.com. Alternatively, you may register by calling ICF International at 1-703-934-3173, sending a facsimile to 1-703-934-3470, or sending an e-mail to Ms. Ami Parekh Gordon at AGordon3@icfi.com.
Additional Information: EPA welcomes public attendance at the “Peer Consultation Workshop on Cumulative Mixtures Risk of Six Selected Phthalates” and will make every effort to accommodate persons with disabilities. For information on access or services for individuals with disabilities, or if you have any other questions related to this workshop please contact Ms. Ami Parekh Gordon of ICF International at AGordon3@icfi.com or by phone at 1-703-934-3173.End Preamble Start Supplemental Information
I. Information About IRIS
EPA's IRIS is a human health assessment program that evaluates quantitative and qualitative risk information on effects that may result from exposure to chemical substances found in the environment. Through the IRIS Program, EPA provides the highest quality science-based human health assessments to support the Agency's regulatory activities. The IRIS database contains information for more than 550 chemical substances that can be used to support the first two steps (hazard identification and dose-response evaluation) of the risk assessment process. When supported by available data, IRIS provides oral reference doses (RfDs) and inhalation reference concentrations (RfCs) for chronic noncancer health effects and cancer assessments. Combined with specific exposure information, government and private entities use IRIS 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.
The IRIS cumulative assessment will address the specific recommendations presented in the NAS report on cumulative risk for phthalates and expand the discussion to other approaches that may also be applicable. The 2008 NAS report recommended that:
○ EPA group chemicals that cause common adverse outcomes and not focus exclusively on structural similarity or on similar mechanisms of action, and
○ Phthalates and other agents that cause androgen insufficiency or block androgen-receptor signaling, and are thus capable of inducing effects that characterize components of the phthalate syndrome, should be considered in a cumulative risk assessment.
In response to NAS recommendations, EPA is conducting research to: (1) Determine whether prenatal exposures to phthalates are associated with adverse effects in male and female offspring; (2) determine how phthalates interact in mixtures with other phthalates, toxic substances, and pesticides to induce adverse effects, in particular disruption of reproductive development in males and females; and (3) determine approaches to integrate new data on multiple phthalates into a cumulative mixtures assessment.
