1 For combinations of radioactive
				materials, the licensee shall be required to consider whether a contingency
				plan is needed if the sum of the ratios of the quantity of each radioactive
				material authorized to the quantity listed in this table for that material
				exceeds one.
2 Waste packaged in type B
				containers shall not require a contingency plan.
