The definitions contained in chapter 81.108 RCW and RCW 81.04.010 are incorporated by reference in this section. To the extent that any of the definitions in this chapter differ from statutory definitions, the statutory definitions shall control.

"Affiliated interest" means a person or corporation as defined in RCW 81.16.010.

"Commission" means the Washington utilities and transportation commission.

"Control" means the possession, direct or indirect, of the power to direct or cause the direction of the management and policies of a company, whether through the ownership of voting shares, by contract, or otherwise.

"Effective rate" means the highest permissible rate, for the disposal of low-level radioactive waste, calculated as the lowest contract rate plus an administrative fee, if applicable, determined pursuant to RCW 81.108.040.

"Extraordinary volume" means volumes of low-level radioactive waste delivered to a site caused by nonrecurring events, outside normal operations of a generator, that are in excess of twenty thousand cubic feet or twenty percent of the preceding year's total volume at such site, whichever is less.

"Extraordinary volume adjustment" means a mechanism that allocates the potential rate reduction benefits of an extraordinary volume among all generators and the generator responsible for such extraordinary volume as described in RCW 81.108.070.

"Generator" means a person, partnership, association, corporation, or any other entity that, as a part of its activities, produces low-level radioactive waste.

"Inflation adjustment" means a mechanism that adjusts the maximum disposal rate by a percentage equal to the change in price levels in the preceding period, as measured by a common, verifiable price index as determined in RCW 81.108.040.

"Low-level radioactive waste" means waste material that contains radioactive nuclides emitting primarily beta or gamma radiation, or both, in concentrations or quantities that exceed applicable federal or state standards for unrestricted release. Low-level waste does not include waste containing more than ten nanocuries of transuranic contaminants per gram of material, nor spent reactor fuel, nor material classified as either high-level waste or waste which is unsuited for disposal by near-surface burial under any applicable federal regulations nor naturally occurring or accelerator produced radioactive material.

"Maximum disposal rate" the maximum disposal is the rate a site operator may charge generators as provided in RCW 81.108.050.

"Site" means a location, structure, or property used or to be used for the storage, treatment, or disposal of low-level radioactive waste for compensation within the state of Washington.

"Site operator" means a low-level radioactive waste site operating company, which includes every corporation, company, association, joint stock association, partnership, and person, their lessees, trustees, or receivers appointed by any court whatsoever, owning, operating, controlling, or managing a low-level radioactive waste disposal site or sites located within the state of Washington.

"Subsidiary" means any company in which the low-level waste company owns directly or indirectly five percent or more of the voting securities, unless the low-level waste company demonstrates it does not have control.

"Volume adjustment" means a mechanism that adjusts the maximum disposal rate in response to material changes in volumes of waste deposited at the site during the preceding period so as to provide a level of total revenues sufficient to recover the costs to operate and maintain the site.
