          - [Docket No. A-2000-38; FRL-6945-8] 

# AGENCY:

U.S. Environmental Protection Agency, U.S. Department of Energy, and the U.S. Nuclear Regulatory Commission.

# ACTION:

Notice of availability and comment.

# SUMMARY:

The U.S. Environmental Protection Agency (EPA), U.S. Department of Energy (DOE), and the U.S. Nuclear Regulatory Commission (NRC) are announcing the availability for comment of the draft document, Approach for Developing a Web Accessible Catalog of Dose and Risk Models and their Capabilities. The purpose of the document is twofold and is organized in two Sections: Section 1 is to provide model users with general guidance and performance considerations regarding how to select radiation dose and risk assessment models for use in site cleanup activities and decision making; Section 2 is to provide a catalog of available dose and risk models, to include descriptions of each model's attributes and performance capabilities in response to the model selection and performance considerations presented in Section 1. The complete document will be in the form of an “on-line catalog” accessible via the Internet, where model users can directly download guidance and information on model capabilities, and model developers can directly input performance information concerning their models. It will combine information that has been developed by ISCORS member agencies regarding model selection criteria with the capabilities of specific models. The public comment period for the document containing the model selection criteria will last 120 days from the date of this notice. Specifically, we are seeking comments on: (1) The general approach for the document and use of the Internet for model user and developer access for uploading and downloading information; and (2) the proposed guidance and set of questions to assist a user in selecting an appropriate model that is responsive to the user's needs. Comments should be sent to the EPA or NRC docket or to the agency contacts listed below. Following the close of the comment period, the agencies will review the public comments and suggested changes will be incorporated, where appropriate, in response to those comments. A final draft of the model selection criteria will then be made available to the public. Model-specific capabilities will then be added by model users and developers. 

# DATES:

Comments received by June 21, 2001 will be considered. Comments received after that date will be considered if it is practical to do so, but no assurance can be given for consideration of late comments.
