Current through Register Vol. 50, No. 6, June 20, 2024
A. Near-Surface Disposal Facility Operation
				  and Disposal Site Closure
1. Wastes
				  designated as Class A pursuant to LAC 33:XV.438 shall be segregated from other
				  wastes by placing in disposal units which are sufficiently separated from
				  disposal units for the other waste classes so that any interaction between
				  Class A wastes and other wastes will not result in the failure to meet the
				  performance objectives of this Chapter. This segregation is not necessary for
				  Class A wastes if they meet the stability requirements in LAC
				  33:XV.499.Appendix E, Paragraph B.2.
2. Wastes designated as Class C pursuant to
				  LAC 33:XV.438 shall be disposed of so that the top of the waste is a minimum of
				  5 meters below the top surface of the cover or must be disposed of with
				  intruder barriers that are designed to protect against an inadvertent intrusion
				  for at least 500 years.
3. Except
				  as provided in LAC 33:XV.1325.A.12, only waste classified as Class A, B, or C
				  shall be acceptable for near-surface disposal. All waste shall be disposed of
				  in accordance with requirements of LAC 33:XV.1325.A.4-11.
4. Wastes shall be emplaced in a manner that
				  maintains the package integrity during emplacement, minimizes the void spaces
				  between packages, and permits the void spaces to be filled.
5. Void spaces between waste packages shall
				  be filled with earth or other material to reduce future subsidence within the
				  fill.
6. Waste shall be placed and
				  covered in a manner that limits the radiation dose rate at the surface of the
				  cover to levels that at a minimum will permit the licensee to comply with all
				  provisions of LAC 33:XV.414 at the time the license is transferred pursuant to
				  LAC 33:XV.1316.
7. The boundaries
				  and locations of each disposal unit shall be accurately located and mapped by
				  means of a land survey. Near surface disposal units shall be marked in such a
				  way that the boundaries of each unit can be easily defined. Three permanent
				  survey marker control points, referenced to United States Geological Survey
				  (USGS) or National Geodetic Survey (NGS) survey control stations, shall be
				  established on the site to facilitate surveys. The USGS or NGS control stations
				  shall provide horizontal and vertical controls as checked against USGS or NGS
				  record files.
8. A buffer zone of
				  land shall be maintained between any buried waste and the disposal site
				  boundary and beneath the disposed waste. The buffer zone shall be of adequate
				  dimensions to carry out environmental monitoring activities specified in LAC
				  33:XV.1326.D and take mitigative measures if needed.
9. Closure and stabilization measures as set
				  forth in the approved site closure plan shall be carried out as each disposal
				  unit is filled and covered.
10.
				  Active waste disposal operations shall not have an adverse effect on completed
				  closure and stabilization measures.
11. Only wastes containing or contaminated
				  with radioactive material shall be disposed of at the disposal site.
12. Proposals for disposal of waste that is
				  not generally acceptable for near-surface disposal because the waste form and
				  disposal methods must be different and, in general, more stringent than those
				  specified for Class C waste, may be submitted to the Office of Environmental
				  Compliance for approval.
