An "A" rating means that the site is acceptable for that site factor.(b)
An "M" rating means the site factor is acceptable with modification or restriction to the site or disposal method.1.
M1 - Upslope surface water diversion required.2.

M4 - Acceptable if a curtain drain is installed to lower the water table to a level of eighteen (18) inches below the domestic septage application.(c)
A "U" rating means the site factor is not acceptable. Reclamation site areas with "U" ratings may be acceptable for disposal sites if the disposal activity will not contaminate the groundwater or create a public health nuisance.(2)
