Current through Register Vol. 48, No. 38, September 20, 2024
This Section sets forth the information that must be
considered by the Agency in authorizing a Class I injection well. For an
existing or converted new Class I injection well, the Agency may rely on the
existing permit file for those items of information listed below which are
current and accurate in the file. For a newly drilled Class I injection well,
the Agency must require the submission of all the information listed below. For
both existing and new Class I injection wells, certain maps, cross-sections,
tabulations of wells within the area of review, and other data may be included
in the application by reference, provided they are current, readily available
to the Agency (for example, in the Agency's files) and sufficiently identified
to be retrieved.
a) Prior to the
issuance of a permit for an existing Class I injection well to operate or the
construction or conversion of a new Class I injection well, the Agency must
consider the following:
1) Information
required in 35 Ill. Adm. Code
702.120
through
702.124
and
704.161(c);
2) A map showing the injection well for which
a permit is sought and the applicable area of review. Within the area of
review, the map must show the number, or name, and location of all producing
wells, injection wells, abandoned wells, dry holes, surface bodies of water,
springs, mines (surface and subsurface), quarries, water wells, and other
pertinent surface features including residences and roads. The map should also
show faults, if known or suspected. Only information of public record is
required to be included on this map;
3) A tabulation of data on all wells within
the area of review that penetrate into the proposed injection zone. Such data
must include a description of each well's type, construction, date drilled,
location, depth, record of plugging or completion, and any additional
information the Agency may require;
4) Maps and cross-sections indicating the
general vertical and lateral limits of all underground sources of drinking
water within the area of review, their position relative to the injection
formation, and the direction of water movement, where known, in each
underground source of drinking water that may be affected by the proposed
injection;
5) Maps and
cross-sections detailing the geologic structure of the local area;
6) Generalized maps and cross-sections
illustrating the regional geologic setting;
7) Proposed operating data, including the
following information:
A) The average and
maximum daily rate and volume of the fluid to be injected;
B) The average and maximum injection
pressure; and
C) The source and an
analysis of the chemical, physical, radiological, and biological
characteristics of injection fluids;
8) A proposed formation testing program to
obtain an analysis of the chemical, physical, and radiological characteristics
of and other information on the receiving formation;
9) A proposed stimulation program;
10) The proposed injection
procedure;
11) Schematic or other
appropriate drawings of the surface and subsurface construction details of the
system;
12) Contingency plans to
cope with all shut-ins or well failures so as to prevent migration of fluids
into any underground source of drinking water;
13) Plans (including maps) for meeting the
monitoring requirements in Section
730.113(b);
14) For wells within the area of review that
penetrate the injection zone but are not properly completed or plugged, the
corrective action proposed to be taken pursuant to 35 Ill. Adm. Code
704.193;
15) Construction procedures including a
cementing and casing program; logging procedures; deviation checks; and a
drilling, testing, and coring program; and
16) A certificate that the applicant has
assured, through a performance bond or other appropriate means, the resources
necessary to close, plug, or abandon the well as required by 35 Ill. Adm. Code
704.189.
b) Prior to granting approval for
the operation of a Class I injection well, the Agency must consider the
following information:
1) All available
logging and testing program data on the well;
2) A demonstration of mechanical integrity
pursuant to Section
730.108;
3) The anticipated maximum pressure and flow
rate at that the permittee will operate;
4) The results of the formation testing
program;
5) The actual injection
procedure;
6) The compatibility of
injected waste with fluids in the injection zone and minerals in both the
injection zone and the confining zone; and
7) The status of corrective action on
defective wells in the area of review.
c) Prior to granting approval for the
plugging and abandonment of a Class I injection well, the Agency must consider
the following information:
1) The type and
number of plugs to be used;
2) The
placement of each plug including the elevation of the top and bottom;
3) The type and grade and quantity of cement
to be used;
4) The method for
placement of the plugs; and
5) The
procedure to be used to meet the requirements of Section
730.110(c).
