(1) When injection does not occur into, through, or above an underground source of drinking water, the program director may authorize a well or project with less stringent requirements for area of review, construction, mechanical integrity, operation, monitoring, and reporting than required herein.

(2) When injection occurs through or above an underground source of drinking water, but the radius of endangering influence when computed under ARM 36.22.1425 is smaller or equal to the radius of the well, the program director may authorize a well or project with less stringent requirements for an area of review, operation, monitoring, and reporting than required herein to the extent that the reduction in requirements will not result in an increased risk of movement of fluids into an underground source of drinking water.

(3) When reducing requirements under (1) or (2) of this rule, the program director shall prepare a fact sheet explaining the reasons for the action.
