"Alternative onsite soil evaluator" means an individual licensed by the board to [ construct, install, and repair a treatment works that is not a conventional onsite sewage system and does not result in a point source discharge (1) evaluate soils and soil properties, (2) identify the soil and soil properties in relationship to the effect of these properties on the use and management of these soils as the locations that are acceptable for conventional and alternative onsite sewage systems, (3) to certify in accordance with applicable state regulations and local ordinances that sites are suitable for conventional and alternative onsite sewage systems, and (5) to design conventional and alternative onsite sewage systems suitable for the soils ].
