Section 459.816 - Segregation and disposal of waste1. The licensee shall:(a) Segregate wastes designated as Class A pursuant to NAC 459.8265 to 459.8305, inclusive, from other wastes by placing them in disposal units which are sufficiently separated from disposal units for the other classes of waste so that any interaction between Class A wastes and other wastes will not result in a failure to meet the objectives of disposal. This type of segregation is not necessary for Class A wastes if they meet the requirements for stability in NAC 459.8305.(b) Dispose of wastes designated as Class C: (1) So that the top of the waste is at least 16 feet below the top surface of the cover; or(2) With barriers against intruders that are designed to protect against an inadvertent intrusion for at least 500 years.(c) Dispose of all wastes in accordance with the requirements of subsections 2 to 8, inclusive.2. Wastes must be emplaced in a manner that:(a) Maintains the integrity of packages during emplacement;(b) Minimizes the spaces between packages; and(c) Permits the remaining spaces between packages to be filled.3. Spaces between packages of waste must be filled with earth or other materials to reduce future subsidence within the fill.4. Waste must be placed and covered in a manner that limits the rate of radiation at the surface of the cover to levels that, at a minimum, will permit the licensee to comply with all the provisions of NAC 459.335 at the time the license is transferred pursuant to NAC 459.8215.5. The boundaries and location of each disposal unit must be accurately located and mapped by means of a survey. Disposal units near the surface must be marked in such a way that the boundaries of each unit can be easily identified. Three permanent control points, consisting of survey markers whose location can be found from control stations of surveys of the United States Geological Survey or National Geodetic Survey, must be established on the site to facilitate surveys. The control stations must provide horizontal and vertical controls.6. A buffer zone must be maintained between any buried waste and the boundary of the disposal area and beneath the disposed waste. The buffer zone must be of adequate dimensions to enable the licensee or other custodian of the disposal area to carry out the provisions of subsection 3 of NAC 459.817 and take mitigative measures if needed.7. The licensee shall carry out the measures for closure and stabilization set forth in the approved plan for closure of the site after each disposal unit is filled and covered.8. Current operations of disposal must not adversely affect completed measures for closure and stabilization.9. Only wastes containing or contaminated with radioactive materials may be disposed of at the disposal area.Nev. Admin. Code § 459.816
