Abstract

This report presents a series of methods, guidelines, and procedures that are considered by the staff to be acceptable for designing erosion protection at uranium mill tailings sites in accordance with the requirements of 10 CFR Part 40, Appendix A (Title II sites) and 40 CFR Part 192 (Title I sites). These procedures are intended to assist licensees and applicants in developing erosion protection designs that will prevent radioactive releases due to erosion. Guidance is presented for the design of soil covers, slopes and swales; sacrificial soil outslopes; and rock riprap for slopes, channels, aprons, outlets, and stream banks. Guidance is also presented for methods to determine sediment yield and for acceptable construction specifications. These recommended procedures are based upon the available literature, numerous laboratory testing programs, and extensive field experience.
