TITLE 62: MINING
CHAPTER I: DEPARTMENT OF NATURAL RESOURCES
PART 240 THE ILLINOIS OIL AND GAS ACT
SECTION 240.420 WELL LOCATION EXCEPTIONS WITHIN DRILLING UNIT
Section 240.420 Well Location Exceptions within Drilling Unit
a) Whenever the conditions of a drilling unit render it impractical to drill an oil or gas well at a location conforming to the requirements of Section 240.410, an oil or gas well may be drilled at a nonconforming location as follows:
1) If the proposed location is less than 330 feet (or other applicable setback) from the nearest lease boundary line, the application shall be accompanied by a written agreement or agreements between the applicant and any leaseholders or mineral rights owners (if no leaseholder exist) whose leases or mineral rights are adjacent to and less than 330 feet (or other applicable setback) from the proposed location. In lieu of the submission of a written agreement or agreements, the applicant shall give notice by certified mail, return receipt requested, to any leaseholders or mineral rights owners (if no leaseholders exist) whose leases or mineral rights are adjacent to and less than 330 feet (or other applicable setback) from the proposed location. The notice shall include the proposed location of the well and the reason the location is requested, and shall inform the leaseholders or mineral rights owners that they may file written objections with the Department within 15 days after service of the notice. If a written objection is received, the matter shall be set for hearing, which shall be conducted in accordance with the provisions of Section 240.370(d) of this Part.
2) In determining whether to approve a proposed nonconforming location, the Department will consider the feasibility and expense of drilling on location, any hazard or damage to persons or property or to the environment, and whether the proposed location would adversely affect the correlative rights of any of the owners of the reservoir or result in waste or the drilling of unnecessary wells.
b) If at the time of application, a lease immediately adjacent to a proposed drilling unit has producing wells located less than 330 feet from the common boundary line, then a well on the proposed drilling unit may be located at a distance closer than 330 feet but no closer than the distance to the common boundary line of the immediately offsetting well.
c) If a drilling unit is located over an active mine, the mined-out or inaccessible portion of an active mine, an abandoned mine, or the undeveloped limits of a mine, the proposed well can be located so that it will be drilled into an existing or proposed mine pillar subject to the conditions and limitations set forth in subsections (a) and (b) above.
