Section 1828.11 In Situ
Processing: Performance Standards
a) The person who conducts in situ processing activities shall
comply with 62 Ill. Adm. Code 1817 and this Section.
b) In situ processing activities shall be planned and conducted
to minimize disturbance to the prevailing hydrologic balance by:
1) Avoiding discharge of fluids into holes or wells, other than
as approved by the Illinois Department of Natural Resources (Department);
2) Injecting process recovery fluids only into geologic zones or
intervals approved as production zones by the Department;
3) Avoiding annular injection between the wall of the drill hole
and the casing; and
4) Preventing discharge of process fluid into surface waters.
c) Each person who conducts in situ processing activities shall
submit for approval as part of the application for permit under 62 Ill. Adm.
Code 1785.22, and follow after approval a plan that ensures that all acid -
forming, toxic - forming, or radioactive gases, solids, or liquids constituting
a fire, health, safety, or environmental hazard and caused by mining and
recovery process are promptly treated, confined, or disposed of, in a manner
that prevents contamination of ground and surface waters, damage to fish,
wildlife and related environmental values, and threats to the public health and
safety.
d) Each person who conducts in situ processing activities shall
prevent flow of the process recovery fluid:
1) Horizontally beyond the affected area identified in the
permit; and
2) Vertically into overlying or underlying aquifers.
e) Each person who conducts in situ processing activities shall
restore the quality of affected ground water in the permit area and adjacent
area, including ground water above and below the production zone, to the
approximate premining levels or better, to ensure that the potential for use of
the ground water is not diminished.
