PART 144_UNDERGROUND INJECTION CONTROL PROGRAM--Table of Contents
 
                 Subpart B_General Program Requirements
 
Sec. 144.16  Waiver of requirement by Director.

    (a) When injection does not occur into, through or above an 
underground source of drinking water, the Director may authorize a well 
or project with less stringent requirements for area of review, 
construction, mechanical integrity, operation, monitoring, and reporting 
than required in 40 CFR part 146 or Sec. 144.52 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.
    (b) When injection occurs through or above an underground source of 
drinking water, but the radius of endangering influence when computed 
under Sec. 146.06(a) is smaller or equal to the radius of the well, the 
Director may authorize a well or project with less stringent 
requirements for operation, monitoring, and reporting than required in 
40 CFR part 146 or Sec. 144.52 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.
    (c) When reducing requirements under paragraph (a) or (b) of this 
section, the Director shall prepare a fact sheet under Sec. 124.8 
explaining the reasons for the action.
