(F) The director shall not issue a plan approval for a well serving a public water system, or alteration of such a well, in accordance with Chapter 3745-91 of the Administrative Code, that does not conform to the requirements of this chapter, or which will cause or contribute to contamination of the well or ground water.

(G) The director may grant a variance of this chapter. A public water system requesting a variance shall submit a variance application as part of the process for approval of the well site or well. The variance application shall be reviewed as part of the well site or well approval in accordance with Chapter 3745-9 and Chapter 3745-91 of the Administrative Code. The public water system shall include in the variance application a detailed explanation of the requested variance and a sufficient demonstration of at least the following information:

(1) Contamination of the ground water will not occur as a result of construction and operation of the well.

(2) The public health and welfare will not be endangered from contaminants because of unsatisfactory location, protection, construction, operation or maintenance of the well, subject to requirements of the Safe Drinking Water Act (or SDWA).
