water supply system contained as part of a subdivision
application. Any authority delegated under this section shall be
subject to the following conditions:
(A) The county entity shall demonstrate to the
administrator of the water quality division that all sewage or
water supply systems will be reviewed by a qualified
professional with expertise in surface and groundwater
protection from pollution and safe and adequate water supply
systems;
