During UIC program development, the Agency may identify aquifers and portions of aquifers that are actual or potential sources of drinking water. This identification will provide an aid to the Agency in carrying out its duty to protect all USDWs. An aquifer is a USDW if it fits the definition in 35 Ill. Adm. Code 702.110, even if it has not been identified by the Agency.
BOARD NOTE: See 35 Ill. Adm. Code 702.106. Derived from 40 CFR 144.1(g) (2011).
