  "definition": "A site-specific ground water contaminant limit approved by the regulator and incorporated into the facility’s permit. In approving an ACL, the regulator must find that the presence of the constituent in the ground water at a level below the ACL will not pose a substantial hazard to human health or the environment. In setting an ACL, the regulator must also consider potential adverse effects on ground-water quality and on the quality of hydraulically-connected surface water. EPA has issued guidance to assist regulators and owners/operators in determining when it may be appropriate to set ACLs. [40 CFR 264.94(b) (CFR 2013)]",
