(A) General. Onsite wastewater treatment systems that are intended to treat and dispose of atypical wastewater flow, as described in § 171.071(A)(1), shall be designed in accordance with the requirements of §§ 171.100 through 171.111 that apply to the specific system type proposed, and in accordance with the requirements of § 171.071. In enforcing any additional requirements on an onsite wastewater treatment system with atypical wastewater flow, as described in § 171.071(A), and in accordance with the requirements of § 171.071(A)(1), the Health Officer apply the following guidelines regarding the system design:
(1) Pretreatment. Pretreatment of wastewater shall be sufficient to provide effluent suitable for the proposed disposal process. Any requirement for pretreatment that is beyond the specifications of this ordinance shall be established based upon projections of wastewater strength, wastewater components, peak flows, soil conditions, or other factors recognized by standard practice as stressful to onsite wastewater treatment systems in order to achieve the performance objectives as described in § 171.101.
(2) Effluent application. Application of effluent to a soil treatment system shall be designed to preserve the infiltrative capacity of the soil. Consideration shall be given to application methods, such as dosing and alternating soil treatment components, and to the potential effect on the soil matrix, such as clogging and groundwater mounding in order to achieve the performance objectives as described in § 171.101.
(3) Management responsibility. Management and operational procedure and responsibility shall be closely established and provided for in a recordable covenant, or other legal agreement(s) as determined by the Health Officer to assure compliance with the performance objectives as described in § 171.101.
