Illinois Administrative Code › Title 62 - MINING › Part 240 - THE ILLINOIS OIL AND GAS ACT › Subpart G - WELL CONSTRUCTION, OPERATING AND REPORTING REQUIREMENTS FOR CLASS II UIC WELLS › Section 240.760 - Establishment of Internal Mechanical Integrity for Class II UIC Wells

Current through Register Vol. 48, No. 28, July 12, 2024
a) For purposes of
				this Section, establishment of internal mechanical integrity includes proper
				placement of the packer in accordance with subsection (b) and successful
				completion of a pressure test in accordance with subsection (g). If the
				Department determines that the packer is not set in accordance with subsection
				(b) or (c), the permittee shall be required to remove the tubing and packer
				from the well and reset it in the presence of a Department representative in
				accordance with this Section.
b)
				Injection shall be through tubing and packer unless alternative construction
				methods are approved by the U.S. Environmental Protection Agency. The packer
				shall be placed no higher than 200 feet above the uppermost permitted
				perforations or the casing seat in an open hole completion, provided the packer
				is within the cemented portion of the production casing such that there is at
				least 50 feet of cement above the packer, and further provided the packer is no
				less than 100 feet below the base of the fresh water. No perforations shall be
				left open above the packer unless they are isolated by a dual packer or
				concentric packer system. If a dual packer is used, the uppermost packer must
				satisfy the placement requirements of this subsection.
c) If the packer cannot be set in accordance
				with subsection (b) due to existing well construction, casing leaks within the
				cemented portion of the production casing, or an obstruction in the well, the
				permittee may request and the Department may specify an alternative packer
				setting depth provided the packer remains within the cemented portion of the
				production casing. In determining an alternative packer setting depth the
				Department shall take into consideration the current construction of the well,
				the depth of the fresh water and the nature of the obstruction.
d) The permittee shall contact the District
				Office in which the well is located at least 24 hours prior to the initial
				setting or any resetting of the packer in a Class II UIC well to enable an
				inspector to be present when the packer is set. Setting of the packer must be
				reported on a form prescribed by the Department.
e) An internal mechanical integrity test
				shall be performed:
1) prior to initial
				injection into a newly permitted Class II UIC well;
2) prior to initial injection into a Class II
				UIC well after a change to a new, permitted injection zone;
3) prior to resuming injection into any Class
				II UIC well after any workover of the well involving the resetting or movement
				of a packer;
4) prior to initial
				injection into a Class II UIC well after the well has been reactivated from
				temporary abandonment status;
5)
				whenever the Department has reason to believe, based upon well records or field
				observation, and subject to the provisions of Sections
				240.140,
				240.150 and
				240.180,
				that the Class II UIC well may be leaking or improperly constructed;
				and
6) at least once every 5 years
				measured from the date of the last successful test unless a temporary
				abandonment is approved in accordance with Section
				240.1132.
