Design Approval Required. Commercially manufactured wastewater treatment components an d systems must not be used in constructing a subsurface sewage system unless the design is approved by the Director . The Department developed recommended standards and guidance for these systems in the TGM. Approval may b e limited to those locations or conditions where achievement of standards has been demonstrated. Commercially manufactured wastewater treatment components and systems may include but are not limited to: (7-1-25) a. ETPSs (e.g., aerobic treatment systems); (3-31-22) b. PWTPs; and (7-1-25) c. Proprietary non-discharging systems (e.g., individual wastewater incinerators, composting toilets , or vault toilets). (3-31-22) 02. Plan and Specification Submittal. Plans and specifications for all commercially manufacture d wastewater treatment components and systems must be submitted to the Director for approval. Plans and specifications must include detailed construction drawings; capacities; structural calculations; lists of materials ; performance standards; manufacturers’ installation, operation, and maintenance instructions; installation inspectio n checklist; and other relevant information requested by the Director. (7-1-25) a. Manufacturers seeking approval for ETPSs or PWTPs that reduce total suspended solids (TSS) an d carbonaceous biological oxygen demand 5-day (CBOD5) when used with residential strength wastewater mus t submit NSF/ANSI 40 approvals, reports, and associated data or equivalent third-party standards. (7-1-25) b. Manufacturers seeking approval for ETPSs or PWTPs that reduce total nitrogen (TN) must submit NSF/ANSI 245 approvals, reports, and associated data or equivalent third-party standards. (7-1-25) 03. ETPS. (7-1-25) a. In addition to the items in Subsection 009.02, ETPS plan and specification submittals must include: (7-1-25) i. A plan for training and certifying system installers and service providers under Section 006; (3-31-22) ii r ETPSs or PWTPs that reduce total nitrogen (TN) must submit NSF/ANSI 245 approvals, reports, and associated data or equivalent third-party standards. (7-1-25) 03. ETPS. (7-1-25) a. In addition to the items in Subsection 009.02, ETPS plan and specification submittals must include: (7-1-25) i. A plan for training and certifying system installers and service providers under Section 006; (3-31-22) ii. A manual containing all operation and maintenance specified by the design engineer o r manufacturer and the Department; and (7-1-25) iii. A quality assurance project plan documenting how sampling will occur if required by the Directo r for product approval and continued monitoring. (7-1-25) b. Design and installation of these systems must meet the following: (3-31-22) i. The effluent is discharged to a drainfield meeting the requirements of a standard drainfield a s directed in Section 008 or a Director-approved alternative. (3-31-22) ii. If vertical separation distances are reduced from the distances defined in the table in Subsectio n 008.01.c., the reduced separation must protect groundwater quality and a sampling port must be installed to provid e access to representative samples of the effluent from the system. (7-1-25) c. Within thirty (30) days of completing installation of an ETPS, the property owner must provide certification to the health district from a representative approved by the manufacturer that the system has bee n installed and will operate in accordance with the manufacturer’s recommendations. The health district must no t finalize the installation permit until the certification of proper installation and operation is received and include s information on the manufacturer, product, model number, and serial number of the ETPS installed. (7-1-25) d ative approved by the manufacturer that the system has bee n installed and will operate in accordance with the manufacturer’s recommendations. The health district must no t finalize the installation permit until the certification of proper installation and operation is received and include s information on the manufacturer, product, model number, and serial number of the ETPS installed. (7-1-25) d. Property owners with an ETPS installed on their property must have all operation, maintenance, and monitoring requirements specified in the permit completed by June 30 of each year by a certified service provide r in accordance with Section 006, including effluent monitoring if required by the permit. The certified servic e provider who completed operation, maintenance, and monitoring for the system as specified in the TGM must submit an annual report to the Director by July 31 of each calendar year demonstrating the system is working as designed. (7-1-25) e. Permit requirements for ETPSs transfer with ownership changes. Before transferring ownership o f a property with an ETPS, the system owner must notify all transferees of the ETPS operation, maintenance, and monitoring requirements. (7-1-25) 04. PWTPs. (7-1-25) a. System media used with a PWTP must: (7-1-25) i. Be constructed or manufactured from materials that are non-decaying and non-deteriorating and d o not leach unacceptable chemicals when exposed to sewage and the subsurface soil environment; (3-31-22) ii. Support the distribution pipe and provide suitable effluent distribution and infiltration rate to th e absorption area at the soil interface; and (3-31-22) iii. Maintain the integrity of the trench or bed. The material used, by its nature and manufacturer- prescribed installation procedure, must withstand the physical forces of the soil sidewalls, soil backfill, and weight o f equipment used in the backfilling. (7-1-25) b pipe and provide suitable effluent distribution and infiltration rate to th e absorption area at the soil interface; and (3-31-22) iii. Maintain the integrity of the trench or bed. The material used, by its nature and manufacturer- prescribed installation procedure, must withstand the physical forces of the soil sidewalls, soil backfill, and weight o f equipment used in the backfilling. (7-1-25) b. Drainfield size is based on the requirements of a standard drainfield or the manufacturer’ s recommended minimum sizing requirement; and (7-1-25) c. A system using a PWTP may be required to follow the same operation, maintenance, monitoring , and reporting requirements described in Subsection 009.03.d. due to product complexity and site-specific constituen t reduction requirements. (7-1-25) d. Permit requirements for these systems transfer with ownership changes. Before transferrin g ownership of a property with this system, the system owner must notify all transferees of the system operation, maintenance, and monitoring requirements. (7-1-25) 05. Design Approval Effect. The Director may condition a design approval by specifyin g circumstances under which the component must be installed, used, operated, maintained, or monitored. (7-1-25) a. The Director will specify the complex alternative systems that must undergo professionall y managed operation, maintenance, service, or effluent testing. (7-1-25) b. Manufacturers will provide training to a reasonable number of service providers to perform required operation, maintenance, or monitoring as specified by the Director. (7-1-25) c. Manufacturers may enter into agreements with certified service providers trained in thei r technology but must not limit service providers from training in the technology of other manufacturers. (7-1-25) 06. Design Disapproval Notice will provide training to a reasonable number of service providers to perform required operation, maintenance, or monitoring as specified by the Director. (7-1-25) c. Manufacturers may enter into agreements with certified service providers trained in thei r technology but must not limit service providers from training in the technology of other manufacturers. (7-1-25) 06. Design Disapproval Notice. If the Director determines the component described in the submitta l does not comply with or may not consistently function in compliance with these rules, or the manufacturer of th e proposed system failed to comply with Subsection 009.03, the Director will disapprove the design as submitted an d notify the manufacturer or distributor submitting the design, in writing, of the disapproval and the reason for tha t action.
