S.D. Admin. R. 74:29:11:29
The permit shall include maximum injection volume and pressure limits that may not be exceeded to ensure that fractures are not initiated or propagated in the confining zone or zones, injected fluids do not migrate into any unauthorized zone or underground source of drinking water, and formation fluids are not displaced into any unauthorized zone or underground source of drinking water. At a minimum, operating requirements shall specify, except during well stimulation, that injection pressure at the wellhead be calculated to ensure that the pressure in the production zone during injection does not initiate new fractures or propagate existing fractures. In no case may injection pressure initiate fractures in the confining zone or zones, if confinement is present, or cause the migration of injection of formation fluids into an unauthorized zone or underground source of drinking water. Injection between the outermost casing protecting unauthorized zones and the well bore is prohibited.
