Download as PDF 48950 Federal Register / Vol. 70, No. 161 / Monday, August 22, 2005 / Notices In October 1988, we held the Fourth Conference on Air Quality Modeling. Its purpose was to advise the public on new modeling techniques and to solicit comments to guide our consideration of any rulemaking needed to further revise the Guideline. We held the Fifth Conference on Air Quality Modeling in March 1991, which served as a public hearing for the proposed revisions to the Guideline. In August 1995, we held the sixth conference as a forum to update our available modeling tools with stateof-the-science techniques for airing these issues and for the public to offer new ideas. The last conference held was the Seventh Conference on Air Quality Modeling in June 28 and 29, 2000, which served as a public hearing for the proposed changes to the recommended air quality models in Appendix W. Several presentations were made, including the development of an enhanced Gaussian dispersion model with boundary layer parameterization (AERMOD 1); the development of the CALPUFF modeling system by Earth Tech, Inc. through the Interagency Workgroup on Air Quality Modeling (IWAQM 2); the development and testing of ISC-PRIME by the Electric Power Research Institute’s building downwash program; and on revisions to the Emissions and Dispersion Modeling System (EDMS) by the Federal Aviation Administration. In addition, several presentations on models for consideration as ‘‘alternative models’’ were made and a panel of experts discussed meteorological data assimilation for the next generation of dispersion models. The proceedings are found in Docket No. A–99–05. Public Participation The Eighth Conference on Air Quality Modeling will be open to the public; no admission fee is charged and there is no formal registration. The conference will begin the first morning with introductory remarks by the presiding EPA official. The following topics will be presented: I. AERMOD implementation issues; II. CALPUFF implementation issues; III. Assimilated meteorological data for air dispersion models; 1 AMS/EPA Regulatory MODel; AERMOD is being developed by AERMIC: AMS/EPA Regulatory Model Improvement Committee. 2 IWAQM was formed in 1991 to provide a focus for development of technically sound regional air quality models for regulatory assessments of pollutant source impacts on federal Class I areas. IWAQM is an interagency collaboration that includes efforts by EPA, U.S. Forest Service, National Park Service, and Fish and Wildlife Service. VerDate jul<14>2003 16:09 Aug 19, 2005 Jkt 205001 IV. New approach for updating (revising) models; V. Alternative approaches for selection of approved dispersion models; and, VI. Other presentations by the public. Those wishing to speak at the conference, whether to volunteer a presentation on a special topic or to offer general comment on any of the modeling techniques scheduled for presentation, should contact us at the address given in the FURTHER INFORMATION section (note the cutoff date). Such persons should identify the organization (if any) on whose behalf they are speaking and the length of presentation. If a presentation of general comments is projected to be longer than 10 minutes, the presenter should also state why a longer period is needed. Persons failing to submit a written notice but desiring to speak at the conference should notify the presiding officer immediately before the conference and they will be scheduled on a time-available basis. The conference will be conducted informally and chaired by an EPA official. There will be no sworn testimony or cross examination. A verbatim transcript of the conference proceedings will be produced and placed in the docket. Speakers should bring extra copies of their presentation for inclusion in the docket and for the convenience of the reporter. Speakers will be permitted to enter into the record any additional written comments that are not presented orally. Additional written statements or comments should be sent to the OAR Regulatory Docket (see ADDRESSES section). A transcript of the proceedings and a copy of all written comments will be maintained in Docket OAR–2005–0157 which will remain open until October 24, 2005 for the purpose of receiving additional comments.

EPA is extending the public comment period to October 14, 2005, in response to requests for extension of the comment period. EPA intends to make comments received by the end of the extended public comment period (October 14, 2005) available to Versar, Inc., an EPA contractor for external scientific peer review, for the external peer review panelists prior to the anticipated workshop. The U.S. EPA will consider all comments received by October 14, 2005, in preparing a final report. EPA still expects Versar, Inc., to convene a panel of experts and organize and conduct an external peer-review workshop. This workshop will be announced in a separate Federal Register notice, once EPA is notified by Versar, Inc., of the date and location for the workshop.

SUPPLEMENTARY INFORMATION: 

I. Information About the Document

    Physiologically-based pharmacokinetic (PBPK) models represent an 
important class of dosimetry models that are useful for predicting 
internal dose at target organs for risk assessment applications. Dose-
response relationships that appear unclear or confusing at the 
administered dose level can become more understandable when expressed 
on the basis of internal dose of the chemical. To predict internal dose 
level, PBPK models use pharmacokinetic data to construct mathematical 
representations of biological processes associated with the absorption, 
distribution, metabolism, and elimination of compounds. With the 
appropriate data, these models can be used to extrapolate across 
species and exposure scenarios, and address various sources of 
uncertainty in risk assessments. This external review draft document 
addresses the following questions: (1) Why do risk assessors need PBPK 
models; (2) How can these models be used in risk assessments; and (3) 
What are the characteristics of acceptable PBPK models for use in risk 
assessment?

II. How To Submit Technical Comments to EPA's E-Docket

    EPA has established an official public docket for information

public docket is available for public viewing at the Office of 
Environmental Information (OEI) Docket in the Headquarters EPA Docket 
Center, (EPA/DC) EPA West Building, Room B102, 1301 Constitution Ave., 
NW., Washington, DC. The EPA Docket Center Public Reading Room is open 
from 8:30 a.m. to 4:30 p.m., Monday through Friday, excluding legal 
holidays. The telephone number for the Public Reading Room is (202)

containing copyrighted material, EPA will provide a reference to that 
material in the version of the comment that is placed in EPA's 
electronic public docket. The entire printed comment, including the 
copyrighted material, will be available in the official public docket.

delivered to the EPA Docket Center will be transferred to E-Docket. 
Public comments that are mailed or delivered to the EPA Docket Center 
will be scanned and placed in E-Docket. Where practical, physical 
objects will be photographed, and the photograph will be placed in E-
Docket with a brief description written by the docket staff.
    You may submit comments electronically, by mail, by facsimile, or
