Section 0400-45-06-.05 - INJECTED FLUID STANDARDS
Current through September 24, 2024
(1) Any fluid injected into or above a USDW shall meet the following standards unless specific alternate standards are established by the Commissioner for the individual discharge based on hydrogeologic setting, character of the injectate, risk to the environment and persons utilizing the ground water resource and compliance with subparagraph (j) of this paragraph:
The injected fluid shall contain dissolved oxygen in at least the amount that naturally occurs in that portion of the aquifer where the injection occurs.
The injected fluid shall contain no oil and grease other than that of natural origin in that portion of the aquifer where the injection occurs.
The injected fluids shall contain no color or turbidity other than that of natural origin in that portion of the aquifer where the injection occurs.
The concentration of a fecal coliform group shall not exceed 200 per 100 ml. as a geometric mean based on a minimum of 10 samples collected from a given sampling point over a period of not more than 30 consecutive days with individual samples being collected at intervals of not less than 12 hours. For the purposes of determining the geometric mean, individual samples having a fecal coliform group concentration of less than 1 per 100 ml. shall be considered as having a concentration of 1 per 100 ml. In addition, the concentration of the fecal coliform group in any individual sample shall not exceed 1,000 per 100 ml.
The injected fluids shall have no taste or odor other than that which naturally occurs in that portion of the aquifer where the injection occurs.
The injected fluids shall have a pH level as naturally occurs in that portion of the aquifer where the injection occurs or as may result from normal agricultural, or silviculture activity provided all reasonable controls are used.
The injected fluids shall be free from chemical constituents, other than those of natural origin, in that portion of the aquifer where the injection occurs, in concentrations specified in Rule 0400-45-01-.19 or combinations which would be harmful to human, animal or aquatic life or detrimental to the most sensitive and governing water use. Criteria for chemical constituents contained in guidelines published by the US Environmental Protection Agency shall be considered.
The injected fluid shall be free of distinctly visible solids, scum, foam, or oily sleek other than those of natural origin in that portion of the aquifer where the injection occurs.
The injected fluid shall contain no other pollutants that may be detrimental to public health or impair the usefulness of the water for the most sensitive and governing water use.
Authority: T.C.A. §§ 69-3-101 et seq. and 4-5-201 et seq.
