(A) Approved leaching trench products utilizing a non-gravel fines-free distribution system shall receive approval of the director through one of two processes as follows:
(1) For the two product types meeting the description provided in paragraphs (A) (1)(a) and (A)(1)(b) of this rule, approval may be granted by the director after administrative review. Manufacturers or their authorized representatives whose chamber and bundled expanded polystyrene distribution media products meet the specifications in paragraphs (A)(1)(a) and (A)(1)(b) of this rule shall submit technical, design, performance, installation, and O&M information to support all manufacturer claims as requested by the director for administrative review. Installation information shall include a product-specific installation checklist for use by contractors and inspectors. The checklist shall provide enough information to guide installations and inspections. Upon administrative review the director may approve or disapprove the chamber or expanded polystyrene bundle system. If the director disapproves the manufacturer's request, the manufacturer may seek approval through the process specified in section 3718.04 of the Revised Code.
(a) Chamber distribution products eligible for administrative approval shall:
(i) Eliminate the need for gravel leaching trenches and replace it with an open bottom, plastic chamber;
(ii) Provide adequate void space for the passage and temporary storage of effluent. Adequate void space shall be considered the volume of void space provided by the equivalent area of a gravel leaching trench;
(iii) Provide suitable effluent distribution and provide an interface with the infiltrative surface of the trench bottom and side wall soil for absorption of the effluent; and
(iv) Be certified by the IAPMO to meet property standards PS 63-2005 et seq.
(b) Bundled expanded polystyrene distribution media products eligible for administrative approval shall:
(i) Eliminate the need for traditional gravel and replace it with a perforated pipe surrounded by tightly packed expanded polystyrene aggregate and enclosed in polyolefin netting. When used in combination with expanded polystyrene bundles containing a perforated pipe, additional bundles are not required to contain a perforated pipe;
(ii) Provide adequate void space for the passage and temporary storage of effluent while maintaining a stable density throughout the life of the system. Adequate void space shall be considered the volume of void space provided by the equivalent area of a gravel leaching trench;
(iii) Support the distribution pipe where required, provide for suitable effluent distribution, and provide an interface with the infiltrative surface of the trench bottom and side wall soil for absorption of the effluent;
(iv) Maintain the integrity of the excavation, support soil backfill and cover material, and weight of equipment used in backfilling;
(v) Be fabricated from non-decaying and non-deteriorating materials, meeting applicable industry standards that do not leach unacceptable chemicals when exposed to effluent and the soil environment; and
(vi) Be certified by the IAPMO to meet guide criteria IGC 276-2011 et seq.
(B) A pretreatment component shall only be permitted by a board of health for use in a STS if approved by the department of health in accordance with this rule and section 3718.04 of the Revised Code.
(1) The department of health shall maintain a list of approved pretreatment components and the associated treatment level the product is listed to obtain.
(2) Except as provided in paragraph (D) of this rule, a listed pretreatment component shall be approved for a maximum period of five years, and may be reevaluated at any time during the approval period when there is evidence of noncompliance with this rule or there has been a change in design of the pretreatment component. A manufacturer may apply for renewal of its approval at anytime prior to the end of the approval period , at which point the product will be reevaluated.
(3) Information submitted for renewal or reevaluation shall include an updated list of distributors and service providers and may include additional field or test data, design changes to the product or treatment train, installation or operation modifications, and changes in service provider availability. The department of health may require field testing or monitoring for the purposes of renewal or reevaluation. If a manufacturer does not submit information in accordance with this paragraph, the department of health shall remove the pretreatment component or the manufacturer from the list of approved pretreatment components in accordance with Chapter 119. of the Revised Code.
(4) Pretreatment components are subject to review by the director of health for compliance with the conditions of approval and applicable law and rules. A pretreatment component may be reevaluated at any time when there is evidence of noncompliance with approval conditions or for other reasons deemed necessary to assure compliance. Upon review, if there is a determination of noncompliance, a pretreatment component or the manufacturer may be removed from the approved list in accordance with Chapter 119. of the Revised Code.
(C) Aerobic type treatment systems and applicable special device approvals previously approved by the director of health prior to January 1, 2007 shall be conditionally listed as meeting the CBOD5 and TSS standard in paragraph (A) of rule 3701-29-14 of the Administrative Code for a maximum period of one year, during which time, the manufacturer of the system or device may submit an application for review.
(D) Sewage treatment systems products, including pretreatment components reviewed in accordance with section 3718.04 of the Revised Code by the sewage treatment systems technical advisory committee and/or approved by the director of health after January 1, 2007 and before January 1, 2015 shall continue to be approved as follows:
(1) Products approved prior to January 1, 2009 shall be approved through December 31, 2020;
(2) Products approved between January 1 and December 31, 2009 shall be approved through December 31, 2021;
