                        Robert G. Carpenter, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001, telephone: 301-415-6177 or e-mail to                         *Robert.Carpenter@nrc.gov*.                    

# SUPPLEMENTARY INFORMATION:

## I. Introduction

The U.S. Nuclear Regulatory Commission (NRC) is withdrawing Regulatory Guide 6.8, “Identification Plaque for Irretrievable Well-Logging Sources,” published in October 1978. Regulatory Guide 6.8 provides guidance on acceptable design and mounting practices of the plaques, which are placed at the surface of wells to indicate the presence of an irretrievable well-logging source. The NRC is withdrawing this regulatory guide because it is no longer required.

                    Regulatory Guide 6.8 references Title 10 of the                     *Code of Federal Regulations*                     (10 CFR), Sections 30 and 70, which no longer contain guidance for design or mounting of identification plaques. The current regulation regarding the identification plaques is found in 10 CFR 39.15, “Agreement with Well Owner or Operator.” Regulatory Guide 6.8 is no longer required because the current regulations in 10 CFR 39.15(a)(5) provide a specific description for the design and mounting of identification plaques for irretrievable well-logging sources. The instruction in 10 CFR 39.15(a)(5) is sufficient without further guidance.                

## II. Further Information

Regulatory guides may be withdrawn when their guidance is superseded by congressional action or no longer provides useful information.
