43.90(n)(2) • • terminate when controls are inoperative, When checks indicate the equipment is not operating within the range prescribed for • peak efficiency, actions shall be taken to restore parameters to the prescribed range. When this cannot be done without shutdown and repairs, drying and packaging operations shall cease as soon as practicable. Operations may not be restarted after cessation due to off-normal performance until needed corrective actions have been identified and implemented, All such cessations, corrective actions, and re-starts shall be reported to the Agency in writing within ten days of the subsequent restart. (3) To control dusting from tailings, that portion not covered by standing liquids shall be wetted or chemically stabilized to prevent or minimize blowing and dusting to the maximum extent reasonably achievable. This requirement may be relaxed if tailings are effectively sheltered from wind, as in the case of below-grade disposal. Consideration shall be given in planning tailings disposal programs to methods for phased covering and reclamation of tailings impoundments. To control dusting from diffuse sources, applicants/licensees shall develop written operating procedures specifying the methods of control which will be utilized, (4) Uranium recovery facility operations producing or involving thorium byproduct material shall be conducted in such a manner as to provide reasonable assurance that the annual dose equivalent does not exceed 25 millirems to the whole body, 75 millirems to • the thyroid, and 25 millirems to any other organ of any member of the public as a result of exposures to the planned discharge of radioactive materials to the general environment, radon-220 and its daughters excepted. (5) Uranium and thorium byproduct materials must be managed so as to conform to the applicable provisions of 40 CFR 440, as codified on January 1, 1983. (o) Requirement Alternatives (1) Licensees/applicants may propose alternatives to the specific requirements in 43.60, 43.70, 43.90, and 43.95. The alternative proposals may take into account local or regional conditions including geology, topography, hydrology, and meteorology. (2) The Agency may find that the proposed alternatives meet the Agency's requirements if the alternatives will achieve a level of stabilization and containment of the sites concerned and a level of protection for the public health and safety and the environ- ment from radiological and nonradiological hazards associated with the sites, which is equivalent to, to the extent practi- cable, or more stringent than the level which would be achieved by the requirements of 43.60, 43.70, 43,90, and 43.95 and the standards promulgated by the Environmental Protection Agency in 40 CFR Part 192, Subparts D and E. • 43 - 25 (April 1990)
