Current through all regulations passed and filed through September 16, 2024
(A)
STS designs
shall be prepared and submitted by persons capable of reviewing the soil
evaluation, site conditions, information provided by the homeowner, and these
rules to facilitate the choice of an appropriate, site specific STS and
complete the STS design in compliance with paragraph (B) of this rule.
Designers shall be knowledgeable of the requirements of this chapter and obtain
education as necessary or required by manufacturer for all STS technologies
they intend to design. Designers may complete the STS design while acting
either as an agent of a board of health, or as an independent agent of the
homeowner. Any board of health that employs staff qualified to prepare STS
designs and offers this service may adopt a fee for the preparation of the
design and all associated costs, provided the fee complies with the cost
methodology required in rule
3701-36-14 of the Administrative
Code.
(B)
For the purposes of this chapter, STS designers shall
demonstrate the ability to perform the following tasks required for STS designs
through the submission of complete and accurate designs to the board of
health:
(1)
Estimate STS flows including, daily design flows, and any expected variations
and estimate pollutant concentrations and mass loads exceeding typical
residential sewage strength as defined in paragraph (C) of rule
3701-29-11 of the Administrative
Code.
(2)
Interpret and evaluate all site specific information
including the soil evaluation, site conditions, site prohibitions and
information provided by the owner to determine feasible STS options that will
meet the requirements of this chapter.
(3)
Evaluate site
hydraulics and understand how the proposed STS integrates with the site
topography and grade to site the STS
(4)
Select devices
and components capable of meeting performance requirements based on knowledge
of these rules and STS technologies approved by the director of
health.
(5)
Provide approximate installation and operation costs
of feasible STS options to assist the owner in selection of the STS to
design.
(6)
Prepare a detailed design including all items outlined
in paragraph (C) of this rule which fully complies with this
chapter.
(7)
Delineate by staking or flagging the proposed soil
absorption areas on the site as they relate to topography and
contour.
(8)
Be available to clarify any questions with and make
adjustments to the system design, layout, or operational concerns. It may be
necessary for the designer to meet with the owner, soil scientist, installer,
service provider, or local health department during, prior, and after the
installation.
(C)
The designer or designee shall visit the site where
the STS is to be located during the design process. The proposed location of a
soil absorption component shall be staked or flagged on site to facilitate
protection by the owner or his agent and to demonstrate that it can be
installed as designed. Documentation submitted to the board of health shall be
legible and contain sufficient detail to demonstrate compliance with the
provisions of this chapter. At a minimum the STS design shall include:
(1)
A description of
the dwelling and/or structure(s) to be served by the STS;
(2)
Details on daily
design flow, soil loading rates based on soil evaluation, length along contour,
absorption area dimensions, and if needed, pump selection/sizing, and pressure
distribution network information;
(3)
Rationale if
varying from standards for items such as design flow, waste strength, or length
along contour;
(4)
Identification and a description of all materials and
system devices and components including septic tanks, dosing tanks,
distribution piping, diversion mechanisms, and distribution
materials;
(5)
Identification of applicable sizing requirements for
all STS devices and components;
(6)
If applicable,
identification of the approved system manufacturer and model to be used,
manufacturer O&M instructions, and means of access for O&M equipment to
service the STS;
(7)
Construction and installation notes for the system
installer including manufacturer installation instructions, if
applicable;
(8)
Copies of or electronic access to O&M
requirements, manuals, and instructions for the owner and service
provider;
(9)
A legible scaled site drawing on eight and a half inch
by eleven inch or larger paper showing the layout of the STS on the site. The
drawing shall illustrate:
(a)
The proposed location of STS devices and components
including the location of the soil absorption component as staked or flagged on
site;
(b)
The designated area for complete relocation and
replacement of the STS as staked on site as required by paragraph (G) of rule
3701-29-06 of the Administrative
Code;
(c)
The approximate location of all items designated in
paragraph (G) of rule
3701-29-06 of the Administrative
Code and demonstrate that required isolation distances are met to both the
proposed STS and the replacement area;
(d)
The location of
all surface features that may affect the operation or installation of the STS
including, but not limited to, disturbed areas, drainage features, wooded
areas, and hardscapes;
(e)
The approximate location of soil borings and/or soil
test pits; and
(f)
North directional arrow.
(10)
If necessary or
applicable at least one enlarged, detailed plan view drawing of the system. The
drawing(s) shall illustrate:
(a)
The proposed location and configuration of the system
with proposed absorption area dimensions and elevations;
(b)
Ground surface
elevations and component elevations as necessary to ensure compliance with this
chapter; and
(c)
Any additional information requested by the board of
health.
(11)
If applicable, pump selection information including
the pump curve and system performance curve;
(12)
If applicable,
pressure distribution network description and calculations; and
(13)
Any additional
information required by the board of health.
