Illinois Statutes Chapter 415. Environmental Safety § 5/13.9. Mahomet Aquifer natural gas storage study

(1) use remote sensing technologies, such as helicopter-based time domain electromagnetics, post-processing methods, and geologic modeling software, to examine, characterize, and prepare three-dimensional models of the unconsolidated geologic materials overlying any underground natural gas storage facility located within the boundaries of the Mahomet Aquifer; and

(2) to the extent possible, identify within those unconsolidated geologic materials potential structures and migration pathways for natural gas that may be released from the underground natural gas storage facility.
