Washington Administrative Code › Title 246 - Health, Department of › RADIATION › Chapter 246-250 - Radioactive waste-Licensing land disposal › GENERAL PROVISIONS › Section 246-250-050 - Specific technical information

Current through Register Vol. 24-14, July 15, 2024
The specific technical information shall include the
					 following information needed for demonstration that the performance objectives
					 and the applicable technical requirements of this chapter will be met. The
					 specific technical information shall be in the form of an environmental report
					 which the department can use to independently evaluate the project under the
					 provisions of the State Environmental Policy Act (SEPA):
(1) A description of the natural and
				  demographic disposal site characteristics as determined by disposal site
				  selection and characterization activities. The description shall include
				  geologic, geochemical, geotechnical, hydrologic, ecologic, archaeologic,
				  meteorologic, climatologic, and biotic features of the disposal site and
				  vicinity.
(2) A description of the
				  design features of the land disposal facility and the disposal units. For
				  near-surface disposal, the description shall include those design features
				  related to infiltration of water; integrity of covers for disposal units;
				  structural stability of backfill, wastes, and covers; contact of wastes with
				  standing water; disposal site drainage; disposal site closure and
				  stabilization; elimination to the extent practicable of long-term disposal site
				  maintenance; inadvertent intrusion; occupational exposures; disposal site
				  monitoring; and adequacy of the size of the buffer zone for monitoring and
				  potential mitigative measures.
(3)
				  A description of the principal design criteria and their relationship to the
				  performance objectives.
(4) A
				  description of the design basis natural events or phenomena and their
				  relationship to the principal design criteria.
(5) A description of codes and standards
				  which the applicant has applied to the design and which will apply to
				  construction of the land disposal facilities.
(6) A description of the construction and
				  operation of the land disposal facility. The description shall include as a
				  minimum the methods of construction of disposal units; waste emplacement; the
				  procedures for and areas of waste segregation; types of intruder barriers;
				  onsite traffic and drainage systems; survey control program; methods and areas
				  of waste storage; and methods to control surface water and groundwater access
				  to the wastes. The description shall also include a description of the methods
				  to be employed in the handling and disposal of wastes containing chelating
				  agents or other nonradiological substances that might affect meeting the
				  performance objectives of this chapter.
(7) A description of the disposal site
				  closure plan, including those design features which are intended to facilitate
				  disposal site closure and to eliminate the need for ongoing active
				  maintenance.
(8) An identification
				  of the known natural resources at the disposal site, whose exploitation could
				  result in inadvertent intrusion into the wastes after removal of active
				  institutional control.
(9) A
				  description of the kind, amount, classification, and specifications of the
				  radioactive material proposed to be received, possessed, and disposed of at the
				  land disposal facility.
(10) A
				  description of the quality assurance program tailored to low-level radioactive
				  waste disposal, developed and applied by the applicant for the determination of
				  natural disposal site characteristics and for quality assurance during the
				  design, construction, operation, and closure of the land disposal facility and
				  the receipt, handling, and emplacement of waste. Audits and managerial controls
				  must be included.
(11) A
				  description of the radiation safety program for control and monitoring of
				  radioactive effluents to ensure compliance with the performance objective in
				  WAC 246-250-170 and occupational
				  radiation exposure to ensure compliance with the requirements of chapter
				  246-221 WAC and to control contamination of personnel, vehicles, equipment,
				  buildings, and the disposal site. Both routine operations and accidents shall
				  be addressed. The program description must include procedures, instrumentation,
				  facilities, and equipment.
(12) A
				  description of the environmental monitoring program to provide data to evaluate
				  potential health and environmental impacts and the plan for taking corrective
				  measures if migration is indicated.
(13) A description of the administrative
				  procedures that the applicant will apply to control activities at the land
				  disposal facility.
(14) A
				  description of the facility electronic recordkeeping system.
