PURPOSE: In some phases of the producing life of some reservoirs, large quantities of salt water may be produced along with the oil and gas. Adequate protection of fresh water supplies lies in the proper disposal of this salt water. Rather than allowing the salt water to flow onto the land surface and into streams and rivers, a more satisfactory method of disposal is the injection of this water into permeable subsurface formations that do not contain fresh water. This rule provides that details such as quality and quantity of the water and well construction are to be submitted to the state geologist for approval to insure that potable water supplies are adequately protected.

Before produced fluid may be disposed of by injection into subsurface strata, pertinent data concerning details of the proposed operation, forms OGC-3-I, OGC-4-I and OGC-11 and any other information required shall be submitted to and approved by the state geologist before injection may begin.
