				of injected fluids or fluids in the formation. The holder of the permit shall
				demonstrate the mechanical integrity of the injection well after such a
				fracturing operation and before commencing the injection of fluids.
4. In no case may the pressure of injection
				cause the movement into an underground source of drinking water of injected
				fluids or fluids in the formation.
5. No injection may occur between the
				outermost casing protecting underground sources of drinking water and the well
				bore.

				well, the Director may not require that the well be plugged if the applicant or
