G 8 - Determination of Irrigation Capacity
(a)
In order to determine the absorption quantities of questionable soils other than those listed in Table G-2, the proposed site may be subjected to percolation tests acceptable to the Administrative Authority or determined by the Administrative Authority.
(b)
When a percolation test is required, no mini-leachfield system or subsurface drip irrigation system shall be permitted if the test shows the absorption capacity of the soil is less than 60 minutes/inch or more rapid than five minutes/inch, unless otherwise permitted by the Administrative Authority.
(c)
The irrigation field size may be computed from Table G-2, or determined by the Administrative Authority or a designee of the Administrative Authority.
