Current through Register Vol. 48, No. 28, July 12, 2024
a) Closure Plan.
				The owner or operator of a Class I hazardous waste injection well must prepare,
				maintain, and comply with a plan for closure of the well that meets the
				requirements of subsection (d) and is specified by permit condition. The
				obligation to implement the closure plan survives the termination of a permit
				or the cessation of injection activities. The requirement to maintain and
				implement an approved plan is directly enforceable regardless of whether the
				requirement is a condition of the permit.
1)
				The owner or operator must submit the plan as a part of the permit application
				and, upon approval by the Agency, such plan must be a condition of any permit
				issued.
2) The owner or operator
				must submit any proposed significant revision to the method of closure
				reflected in the plan for approval by the Agency no later than the date on
				which notice of closure is required to be submitted to the Agency pursuant to
				subsection (b).
3) The plan must
				assure financial responsibility, as required in 35 Ill. Adm. Code
				704.189.
4) The plan must include the following
				information:
A) The type and number of plugs
				to be used;
B) The placement of
				each plug including the evaluation of the top and bottom of each
				plug;
C) The type and grade and
				quantity of material to be used in plugging;
D) The method of placement of the
				plugs;
E) Any proposed test or
				measure to be made;
F) The amount,
				size, and location (by depth) of casing and any other materials to be left in
				the well;
G) The method and
				location where casing is to be parted, if applicable;
H) The procedure to be used to meet the
				requirements of subsection (d)(5); and
I) The estimated cost of closure.
5) The Agency must modify a
				closure plan following the procedures of Subpart C of 35 Ill. Adm. Code
				702.
6) An owner or operator of a
				Class I hazardous waste injection well who stops injection temporarily may keep
				the well open if the following conditions are fulfilled:
A) The owner or operator has received
				authorization from the Agency; and
B) The owner or operator has described
				actions or procedures, satisfactory to the Agency, that the owner or operator
				will take actions to ensure that the well will not endanger USDWs during the
				period of temporary disuse. These actions and procedures must include
				compliance with the technical requirements applicable to active injection wells
				unless otherwise waived by permit condition.
BOARD NOTE: An Agency determination on authorizing keeping
				  the well open is in the nature of a permit determination, and the owner or
				  operator may appeal the Agency's determination to the Board.
7) The owner or operator of a well
				that has ceased operations for more than two years must notify the Agency at
				least 30 days prior to resuming operation of the well.
