(A) A system designed according to this part is considered a Type V system. The system must:
(1) Employ design flow values in § 52.12.
(2) Meet or exceed the requirements of § 52.16(B).
(3) Be designed with Vertical Separation that ensures adequate Sewage dispersal and treatment. Design factors to consider include, but are not limited to, effluent quality, loading rates, Groundwater Mounding if loading rates are in excess of those in Table XII in Minn. Rule 7080.23504 or Table X, loading methods, and soil conditions. SSTS must not contaminate underground waters or zones of periodic saturation with viable fecal organisms.
(B) Type V systems can be used on previously developed Sites only when a Type I or Type II system cannot be installed or is not the most suitable treatment.
(C) Type V systems will not be allowed in areas where a new system or modifications to a new system are not feasible if failure occurs.
(D) Type V systems will be allowed for undeveloped Lots only when two Type I or Type II soil treatment and dispersal areas have been identified on the Lot, in addition to the area utilized by the Type III soil treatment and dispersal area. The Lot must be able to accommodate Long-Term Sewage Treatment in addition to the area utilized by the Type V system.
