The system is located in an area where the depth from the natural grade to the anticipated highest seasonal level of groundwater is less than 3 feet;

(3)

The system will receive high strength wastewater; or

(4)

The system will replace another onsite wastewater treatment system and cannot meet the required horizontal setback from a public water well or a public water system's surface water intake point, unless the health officer makes both of the following two findings:

There is no indication that the system to be replaced is adversely affecting the public water source; and

(B)

There is limited potential that the replacement system could impact the public water source.

Monitoring.

(1)

The owner of an alternative onsite wastewater treatment system shall monitor the operation of the system for as long as the system remains in use, in accordance with the sewage regulations.

A person may not use or operate an alternative onsite wastewater treatment system if the owner of that system fails to monitor that system in accordance with the sewage regulations.

(c)

Mitigation measures.

(1)

The owner of a replacement alternative onsite wastewater treatment system that does not conform to applicable horizontal setbacks from a public water well or a public water system's surface water intake point must comply with applicable mitigation measures set forth in the sewage regulations unless the health officer makes the findings set forth in Subsections (a)(4)(A) and (a)(4)(B) of this section.
