**SUPPLEMENTARY INFORMATION:**
**I. Introduction**
The U.S. Nuclear Regulatory Commission (NRC or Commission) is withdrawing Regulatory Guide 4.8, “Environmental Technical Specifications for Nuclear Power Plants,” published in December 1975. Regulatory Guide 4.8 provides guidance to applicants on the preparation of proposed environmental technical specifications and includes a standard format and an identification of their principal content. The NRC is withdrawing this regulatory guide because it is no longer needed.
Regulatory Guide 4.8 was an acceptable method of meeting the requirements of Title 10 of the *Code of Federal Regulations,* Part 50, “Domestic Licensing of Production and Utilization Facilities,” which states that each operating license for a nuclear power plant issued by the NRC will contain such conditions and limitations as the Commission deems appropriate and necessary. Certain environmental conditions and limitations were incorporated into facility operating licenses as environmental technical specifications. Regulatory Guide 4.8 is no longer needed because environmental technical specifications are no longer used. The information is now contained in Environmental Protection Plans that generally appear in Appendix B to the operating license.
**II. Further Information**
The withdrawal of Regulatory Guide 4.8 does not alter any prior or existing licensing commitments based on its use. The guidance provided in this regulatory guide is no longer necessary. Regulatory guides may be withdrawn when their guidance is superseded by congressional action or no longer provides useful information.
