(3) Performance testing and standards for listing ATTs.
(a) Product testing.
(A) ATTs must be tested according to the product standards and testing protocols of NSF/ANSI Standard No. 40 for residential wastewater treatment systems – 2013, NSF/ANSI Standard No. 245 for nitrogen reduction — 2012, or another NSF/ANSI protocol DEQ approves.
(B) For purposes of demonstrating performance to the fecal coliform concentration in treatment standard 2, the ATT shall be followed by a nonchlorinating disinfection device that has been tested according to NSF/ANSI Standard No. 46 – 2012, or the ATT must be tested by collecting and analyzing influent and effluent grab samples at a minimum frequency of 3 days per week and the same duration (26 consecutive weeks) and hydraulic loadings (design and stress loadings) as the NSF/ANSI sample collection requirements for the BOD5, CBOD5, and TSS parameters. The testing must be performed by an ANSI accredited, third-party testing and certification organization whose accreditation is specific to onsite wastewater treatment products, or have been studied under the La Pine National Demonstration Project.
(b) Product performance. An ATT must produce effluent quality equal to or better than treatment standard 1 or 2 defined in section 0100.
(4) ATT model type and size selection. The model, type, and size of the ATT proposed for a system must be consistent with manufacturer recommendations and match the daily design wastewater flow anticipated from the dwelling or facility.
(5) Access ports.
(a) At a minimum, the ATT must have ground-level access ports sized and located to facilitate installing, removing, sampling, examining, maintaining, and servicing components or compartments that require routine maintenance or inspection. Access ports must facilitate:
(A) Visually inspecting and removing mechanical or electrical components;
(B) Removing components that require periodic cleaning or replacement;
(C) Visually inspecting and collecting samples; and
(D) Removing (manual or pumping) accumulated residuals.
(b) Access ports must be protected against unauthorized intrusion. Acceptable protective measures include but are not limited to padlocks or covers that can be removed only with tools.
(6) Malfunction, failure sensing, and signaling equipment.
(a) The system must be designed to prevent untreated waste passing into the absorption field if the plant malfunctions.
(b) The ATT must possess a mechanism or process capable of detecting:
(A) Failure of electrical and mechanical components that are critical to the treatment process; and
(B) High liquid level conditions above the normal operating specifications.
(c) The ATT must possess a mechanism or process capable of notifying the system owner of failures. The mechanism must have circuits separate from pump circuits and deliver a visible and audible signal.
(A) The visual alarm signal must be conspicuous at a distance of 50 feet from the system and its appurtenances.
(B) The audible alarm signal strength must be between 70 and 90 dbA at 5 feet and discernible at a distance of 50 feet from the system and its appurtenances.
(C) The visual and auditory signals must continue to function in the event of electrical, mechanical equipment, or hydraulic malfunction of the system. The audible signal may be disabled for service as long as the visual signal remains active while cause for the alarm is identified and alleviated.
(d) A clearly visible label or plate with instructions for obtaining service must be permanently located near the failure signal.
(7) Data plate.
(a) The ATT must have permanent and legible data plates located on:
(A) The front of the electrical control box if the ATT has an electrical control box or panel; and
(B) The tank, aeration equipment assembly, or riser at a location accessed during maintenance cycles and inspections.
(b) Each data plate must include:
(A) Manufacturer’s name and address;
(B) Model number;
(C) Serial number (required on one data plate only);
(D) Rated daily hydraulic capacity of the system; and
(E) The performance expectations as determined by performance testing and evaluation.
(8) Siting and absorption area construction criteria.
(a) ATTs approved for treatment standard 1 may be sited and sized as follows:
(A) In areas with a temporary water table, as specifications for sand filters in areas with temporary groundwater in OAR 340-071-0290 (Conventional Sand Filter Systems) require.
(B) In areas with permanent groundwater, where 4 feet of separation can be maintained between the bottom of the trench and groundwater and the other criteria in OAR 340-071-0290 (Conventional Sand Filter Systems) can be met.
(C) On sites meeting criteria for standard onsite systems in OAR 340-071-0220 (Standard Subsurface Systems) or for pressurized systems in OAR 340-071-0275 (Pressurized Distribution Systems).
(b) ATTs used in conjunction with approved disinfection and approved nitrogen reduction processes and approved for treatment standard 2 may be sited and sized as follows.
(A) On sites meeting the criteria for treatment standard 1 in subsection (a) of this section.
(B) In areas with a permanent water table, as specifications for sand filters in areas with a permanent water table in OAR 340-071-0290 (Conventional Sand Filter Systems) require.
(c) Any type of absorption area permitted for a sand filter system, including the gravel-less absorption method, may be permitted for an ATT system.
(9) Limited warranty. The ATT manufacturer must:
(a) Warrant all components of the ATT to be free from defects in material and workmanship for a minimum of two years from the date of installation; and
(b) Fulfill the terms of the warranty by repairing or exchanging any components that the manufacturer determines may be defective.
(10) Installation. ATTs must be installed under the manufacturer’s instructions and this division. The installer must be certified by the ATT manufacturer to install the system and provide written certification to the agent that the ATT component was installed under the manufacturer’s instructions and this rule.
(11) Sampling ports. A sampling port must be designed, constructed, and installed to provide easy access for collecting a free falling or undisturbed sample from the effluent stream. The sampling port may be located within the ATT or other system component (such as a pump chamber) if the wastewater stream being sampled is representative of the effluent stream from the ATT.
(12) Operation and maintenance standards. The owner of an ATT system must ensure the ATT and all components of the onsite system are properly operated and timely maintained or decommissioned and the effluent standards in section (3) of this rule are met.
(13) Owner’s manual. The designer of each onsite system using an ATT must provide a comprehensive owner’s manual prepared by the manufacturer or designer to the system owner, manufacturer’s representative, installer, and if requested, the agent before or at the time of installation. The manual may be a collection of individual system component manuals and must include information on system specifications, system installation, operation and maintenance, and troubleshooting and repair. The information must be presented in a manner the owner can easily understand.
(14) Service contracts.
(a) The owner of an ATT system must maintain a contract, under OAR 340-071-0130 (General Standards, Prohibitions and Requirements)(23), with a maintenance provider to serve and maintain the onsite system. A service contract must be entered before the system is installed and must be maintained until the system is decommissioned.
(b) A maintenance provider must be certified by the manufacturer to provide service on an ATT.
