The subject of this letter is the Nuclear Regulatory Commission's acceptance review of the U.S. Department of Energy's (DOE) Topical Report, Evaluation of the Potentially Adverse Condition of Extreme Erosion. During the Quaternary Period' at Yucca Mountain, Nevada, dated March 1993. This review was conducted in accordance with the guidelines established in the NRC Division of High-Level Waste Management Topical Report Review Position Paper (TRPP), provided to DOE on April 7, 1993.

The Nuclear Waste Policy Amendments Act of 1987 established the federal<br/>Office of the Nuclear Waste Negotiator for a 5-year period. The Nuclear<br/>Waste Negotiator, appointed by the President and confirmed by the<br/>Senate, was empowered to attempt to find a state or Indian tribe willing<br/>to host a repository or a monitored retrievable storage (MB) facility for the<br/>permanent or temporary storage of nuclear waste, respectively.

In 1986, the U.S. Department of Energy (DOE) Waste Isolation Pilot Plant (WIPP) Project<br/>Office (WPO) (DOE-WPO) prepared a strategy _ for complying with the Environmental<br/>Protection Agency&#39;s (EPA&#39;s) Standards for the management of transuranic (TRU) waste. 2<br/>Section 3.2.2.2 of the DOE&#39;s report addressed compliance with the Assurance<br/>Requirements found in 40 CFR § 191.143 . One of the Assurance Requirements addresses<br/>the selection of repository sites that contain recoverable natural resources.

Comments contained in this document were received by the U.S. Department of Energy (DOE) on the Report of Early Site Suitability Evaluation (ESSE) of the Potential Repository Site at Yucca Mountain, Nevada, (Younker et al., 1992, SAIC 91/8000). Comments were received from the U.S. Department of Interior, the U.S. Nuclear Regulatory Commission, the State of Nevada, and several local affected governments in Nevada. No comments were received from members of the public.

This work was performed to suggest possible strategies for geoscientific classifications in the siting process of a high-level repository. To develop a feasible method for geoscientific classifications, a number of factors of a philosophical character, related to the purpose of the classifications, need to be accounted for. Many different approaches can be visualized, and this report was not intended to present a complete classification methodology.

The potentially adverse condition identified at 10 CFR 60.122(c)(16), evidence of extreme<br/>erosion during the Quaternary Period, has been determined to not be present at Yucca<br/>Mountain. A literature search for typical hillslope erosion rates in the U.S. and the world was<br/>performed to establish a range of typical values for erosion rates. Low to moderate erosion<br/>rates in the U.S. were identified to range from 2 to 50 centimeters per thousand years (cm/ka)<br/>in semiarid environments.

On January 13, 1993, Governor of the State of Utah, Mike Leavitt officially announced that he was opposing a MRS Facility in the State of Utah and informed San Juan County of his decision which will preclude the County from applying for a Phase IIa feasibility grant. A copy of the policy statement made by Governor Leavitt is attached for your information.

This paper is about the U.S. Environmental Protection Agency (EPA) &quot;Environmental Standards for the Disposal of Spent Nuclear Fuel, High-Level and Transuranic Wastes, &quot; 40 CFR 191. These standards regulate the disposal of radioactive wastes in geologic repositories.

The goal of radioactive waste management in Sweden is to dispose of all radioactive waste products generated at the Swedish nuclear power plants in a safe manner. Furthermore, all other radioactive waste that arises in Sweden shall be safely disposed of.<br/>The Act on Nuclear Activities requires that the owners of the Swedish nuclear power plants adopt the measures that are needed to achieve this goal. The owners of the Swedish nuclear power plants have commissioned the Swedish Nuclear Fuel and Waste Management Company (SKB) to implement the measures that are needed.<br/>
