Texas Administrative Code › Title 30 - ENVIRONMENTAL QUALITY › Part 1 - TEXAS COMMISSION ON ENVIRONMENTAL QUALITY › Chapter 336 - RADIOACTIVE SUBSTANCE RULES › Subchapter H - LICENSING REQUIREMENTS FOR NEAR-SURFACE LAND DISPOSAL OF LOW-LEVEL RADIOACTIVE WASTE › Section 336.709 - Technical and Environmental Analyses

Current through Reg. 49, No. 28; July 12, 2024
The specific technical and environmental information in the
					 application shall also include the following analyses needed to demonstrate
					 that the performance objectives of this subchapter, referenced in §
										336.723 of
					 this title (relating to Performance Objectives), will be met:
(1) Pathways analyzed in demonstrating
				  protection of the general population from releases of radioactivity shall
				  include air, soil, groundwater, surface water, plant uptake, and exhumation by
				  animals. The analyses shall clearly identify and differentiate between the
				  roles performed by the natural disposal site characteristics and design
				  features in isolating and segregating the wastes. The analyses shall clearly
				  demonstrate that there is reasonable assurance that the exposures to humans
				  from the release of radioactivity will not exceed the limits specified in
				  §
										336.724
				  of this title (relating to Protection of the General Population from Releases
				  of Radioactivity). A minimum period of 1,000 years after closure or the period
				  where peak dose occurs, whichever is longer, is required as the period of
				  analysis to capture the peak dose from the more mobile long-lived radionuclides
				  and to demonstrate the relationship of site suitability to the performance
				  objective in this section to the performance objective in §
										336.724
				  of this title.
(2) Analyses of the
				  protection of individuals from inadvertent intrusion shall include
				  demonstration that there is reasonable assurance that the waste classification
				  and segregation requirements will be met and that adequate barriers to
				  inadvertent intrusion will be provided, as required in §
										336.725
				  of this title (relating to Protection of Individuals from Inadvertent
				  Intrusion).
(3) Analyses of the
				  protection of individuals during operations shall include assessments of
				  expected exposures due to routine operations and likely accidents during
				  handling, storage, and disposal of waste. The analyses shall provide reasonable
				  assurance that exposures will be controlled to meet the requirements of
				  Subchapter D of this chapter (relating to Standards for Protection Against
				  Radiation) and §
										336.726
				  of this title (relating to Protection of Individuals during
				  Operations).
(4) Analyses of the
				  long-term stability of the disposal site and the need for ongoing active
				  maintenance after closure shall be based upon analyses of active natural
				  processes such as erosion, mass wasting, slope failure, settlement of wastes
				  and backfill, infiltration through covers over disposal units and adjacent
				  soils, and surface drainage of the disposal site. The analyses shall provide
				  reasonable assurance that there will not be a need for ongoing active
				  maintenance of the disposal site following closure, as required in §
										336.727
				  of this title (relating to Stability of the Disposal Site after
				  Closure).
