225 ILCS 725/8b
No person shall drill, convert or deepen a well for the purpose of disposing of oil field brine or for using any enhanced recovery method in any underground formation or strata without first securing a permit therefor. Such permit shall be obtained as provided in clause (2) of Section 6 and is subject to the fee prescribed in Section 14, except that such fees for Class II UIC wells shall be deposited in the Underground Resources Conservation Enforcement Fund. All injection wells regulated by the Department's Class II UIC program approved pursuant to 40 CFR 147.701, subpart 0, of record on January 1 of each year, except those which are properly plugged, are subject to an annual fee as follows: on January 1, 1988, $50 per well; on January 1, 1989, $75 per well; and on January 1, 1990, $100 per well. Extension of this fee into subsequent years shall be contingent upon authorization of such by the General Assembly. Such fee shall be paid no later than January 31 of each year. Proceeds of such payments shall be deposited in the Underground Resources Conservation Enforcement Fund. The Department may prescribe appropriate rules to implement this Section and to prevent waste, as defined in this Act, in connection with such wells.
