(1) A site evaluation shall be conducted on every site where a new or replacement sewage system is to be installed. (See

    (2) The percolation time shall be determined by
    (a) conducting percolation tests, or
    (b) classifying the soil according to one of the following methods,
           (i) the Unified Soil Classification System as described in MMAH Supplementary Standard SB-6, “Percolation
               Time and Soil Descriptions,” or
          (ii) the Soil Texture Classification as described in Chapter 3 of USDA, “Soil Survey Manual.”
    (See Note A-8.2.1.2.(2))

    (3) Where the percolation time is determined by a percolation test, there shall be a minimum of 3 locations selected,
    suitably spaced to accurately evaluate the leaching bed area, with the highest percolation time of the tests being used.
