(A) Minimum size. In order to be considered for a private sewage disposal system, a future building site shall have a minimum area based on and determined by the soil loading rate, calculated as provided in applicable regulation or rule of the Indiana State Department of Health, of the soil located upon the building site. Those building sites which have a soil loading rate of 0.30 gpd/sq. ft. gallons per day per square foot or less shall have a minimum lot size of 43,560 square feet (1 acre). Those building sites having a soil loading rate of 0.50 gpd/sq. ft. or more must have a minimum lot size of 30,000 square feet (0.69 acre). The soil loading rate for a future building site shall be determined by a soil profile, including no less than three borings per site and with the most restrictive boring used to determine the soil loading rate, performed by a soil scientist using generally recognized methods and consistent with Indiana State Department of Health regulations, guidelines, and rules.
(B) Replacement system. In order to qualify as a future building site, the proposed site must have sufficient suitable area contained within the future building site for the proposed initial private sewage disposal system as well as an additional area (an alternate site meeting the criteria required by state regulations and local ordinances for installation of septic systems) approved by the Health Department, for installation of a second absorption field of similar design and configuration as the proposed initial private sewage disposal system so that additional area may be utilized as necessary to repair or replace the private sewage disposal system.
(C) Existing sites. A proposed initial private sewage disposal system for an existing building site shall conform with existing regulations, guidelines, and rules of the Indiana State Department of Health and this chapter. Such existing building sites shall not be required to be of minimum size or contain an alternate area for a replacement system as stated above.
