(A) Absorption fields for all lots in subdivisions whose plots are fully and formally approved by the local Plan Commission and other public agencies with the responsibility therefore and recorded with the County Recorder prior to September 1, 1991 shall be designed and installed in a manner that best utilizes the existing area and maximizes the potential for replacement, expansion, or repair of the absorption field. No exemptions from the requirements of 410 I.A.C. 6-8.3 et. seq. shall be granted.
(B) Lots in subdivisions that do not qualify under division (A) above shall provide at least two times the required absorption area in suitable soils to allow for the original and one replacement, expansion or repair of the original absorption field. This area shall be reserved for the installation of the original absorption field and one replacement, expansion or repair of the absorption field. The use of the reserved area shall be limited to those uses which will not decrease the size of the reserve area and will not decrease the loading rate of the soils. Use of an alternating valve mechanism to utilize both systems is preferred and shall be implemented upon installation of the repair and/or replacement reserve area system. The existing system may not be removed upon its failure, but shall remain intact on one side of an alternating valve mechanism.
