Uppermost aquifer definition

Uppermost aquifer means the geologic formation nearest the natural ground surface that is an aquifer, as well as lower aquifers that are hydraulically interconnected with this aquifer within the facility's property boundary.
Uppermost aquifer means the geological formation nearest the natural ground surface that is capable of yielding groundwater to wells or springs. It includes lower aquifers that are hydraulically interconnected with this aquifer within the facility property boundary.
Uppermost aquifer means the first geologic formation above or below the bottom elevation of a constructed liner or wastes, where no liner is present, that is an aquifer, and includes any lower aquifer that is hydraulically connected with this aquifer within the facility’s permit area.

AMENDATORY SECTION (Amending WSR 02-17-005, filed 8/8/02, effective 9/8/02) WAC 246-252-030 Criteria related to disposition of uranium mill tailings or wastes. As used in this section, the term "((as low as reasonably achievable" has the same meaning as in WAC 246-220-007. The term)) by-product material" means the tailings or wastes produced by the extraction or concentration of uranium or thorium from any ore processed primarily for its source material content.As required by WAC 246-235-110(6), each applicant for a license to possess and use source material in conjunction with uranium or tho­ rium milling, or by-product material at sites formerly associated with such milling, is required to include in a license application proposed specifications relating to the milling operation and the disposition of tailings or waste resulting from such milling activities. This sec­ tion establishes criteria relating to the siting, operation, decon­ tamination, decommissioning, and reclamation of mills and tailings or waste systems and sites at which such mills and systems are located and site and by-product material ownership. Applications must clearly demonstrate how these criteria have been addressed. The specifications shall be developed considering the expected full capacity of tailings or waste systems and the lifetime of mill operations. Where later ex­ pansions of systems or operations may be likely, the amenability of the disposal system to accommodate increased capacities without degra­ dation in long-term stability and other performance factors shall be evaluated.Licensees or applicants may propose alternatives to the specific requirements in these criteria. The alternative proposals may take in­ to account local or regional conditions, including geology, topogra­ phy, hydrology, and meteorology. The department may find that the pro­ posed alternatives meet the department's requirements if the alterna­ tives will achieve a level of stabilization and containment of the sites concerned, and a level of protection for public health, safety, and the environment from radiological and nonradiological hazards as­ sociated with the sites, which is equivalent to, to the extent practi­ cable, or more stringent than the level which would be achieved by the requirem...
