In the case of wells authorized by permit, these additional requirements shall be imposed by modifying the permit or the permit may be terminated, or appropriate enforcement action may be taken if the permit has been violated.5.5 For Class V wells, if at any time the Director determines that a Class V well may cause a violation of primary drinking water rules under R309-200, the Director shall: A. require the injector to obtain an individual permit;B. order the injector to take such actions, including closure of the injection well, as may be necessary to prevent the violation; orC. take appropriate enforcement action.5.6 Whenever the Director determines that a Class V well may be otherwise adversely affecting the health of persons, the Director may require such actions as may be necessary to prevent the adverse effect.5.7 Class IV Wells A.
