11 Miss. Code R. § 8-2.3-25-2515
If the determination of the probable hydrologic consequences (PHC) required by § 2523 indicates that adverse impacts on or off the proposed permit area may occur to the hydrologic balance, or that acid-forming or toxic-forming material is present that may result in the contamination of surface- or ground-water supplies, then information supplemental to that required under §§ 2511 and 2513 shall be provided to evaluate such probable hydrologic consequences and to plan remedial and reclamation activities. Such supplemental information may be based upon drilling, aquifer tests, hydrogeologic analysis of the water-bearing strata, flood flows, or analysis of other water quality or quantity characteristics which shall be prepared by, or under the direction of a qualified Registered Professional Geologist or Registered Professional Engineer as required by the Department.
