(1) Applicants for licenses, other than renewals, after the effective date of this rule, shall describe in the application how facility design and procedures for operation will minimize, to the extent practicable, contamination of the facility and the environment, facilitate eventual decommissioning, and minimize, to the extent practicable, the generation of radioactive waste.

(2) Licensees shall, to the extent practicable, conduct operations to minimize the introduction of residual radioactivity into the site, including the subsurface, in accordance with the existing radiation protection requirements in chapter 246-221 WAC and radiological criteria for license termination in this chapter.

(3) Each licensee shall make or cause to be made, surveys of areas, including the subsurface, that:

(a) May be necessary for the licensee to comply with the regulations in this chapter; and

(b) Are reasonable under the circumstances to evaluate:

(i) The magnitude and extent of radiation levels;

(ii) Concentrations or quantities of residual radioactivity; and

(iii) The potential radiological hazards of the radiation levels and residual radioactivity detected.

(4) Notwithstanding subsection (3) of this section, records from surveys describing the location and amount of subsurface residual radioactivity identified at the site must be kept with records important for decommissioning, and such records must be retained in accordance with WAC 246-235-075, as applicable.

(5) The licensee shall ensure that instruments and equipment used for quantitative radiation measurements (for example, dose rate and effluent monitoring) are calibrated periodically as required in WAC 246-221-110(2), 246-240-101, and 246-240-104.
