SECTION TWO :   That Building Regulations codified as Title 4, Chapter 2, Section 4-2-7 – Private Sewage Disposal System be amended as follows, to be effective in accordance with Illinois law.
4-2-7: PRIVATE SEWAGE DISPOSAL:
(E) Approved Private Sewage Disposal System:
1. General: A septic tank or Imhoff tank followed by a subsurface seepage system, as described in subsections (F), (G) and (H) of this section is approved for private sewage disposal when designed, constructed, operated, and maintained in accordance with this section.
An aerobic treatment plant discharging to a subsurface seepage system as provided in subsection (J) of this section, may be approved for private sewage disposal when the use of a septic tank or Imhoff tank followed by a subsurface seepage system is demonstrated to not be feasible or desirable given the constraints of a particular property.
NSF 350 certified system using membrane technology discharging to a subsurface seepage system as provided in subsection (J) of this section may be used for the replacement or repair of a private sewage disposal system.
(J) Aerobic Treatment Plants:
General: After the effective date of this Code, aerobic treatment plants shall comply with the requirements of the National Sanitation Foundation (NSF) standard number 40, individual aerobic wastewater treatment, May 1983, and shall bear the NSF seal. A copy of a list of approved aerobic treatment plants may be obtained from the Building Officer.
Class II Effluent: Aerobic treatment systems listed by NSF for Class II effluent (BOD5-60 milligrams per liter and suspended solids 100 milligrams per liter) shall discharge to one of the following:
A subsurface seepage system designed and constructed in accordance with the requirements of subsection (H) of this section.
A sand filter designed and constructed in accordance with the requirements of subsection (I) of this section.
Class I Effluent: Aerobic treatment plants listed by NSF for Class I effluent (BOD5-20 milligrams per liter and suspended solids 40 milligrams per liter) shall discharge to a subsurface seepage field designed and constructed to be at least two-thirds (2/3) the size listed in section 4-2-7-1, appendix G of this section 4-2-7 as obtained from soil investigation.
Sizing: Aerobic treatment plants which are listed by NSF as Class I and rated at five hundred (500) gallons per day may be allowed for the treatment of domestic sewage from dwellings having a maximum of three (3) bedrooms.
Installation: All components of aerobic treatment plants shall be installed at the time of the original installation. If there are practical difficulties, then a solid end cap shall be securely placed over the end of the discharge line until the system can be completed, to prevent a violation of subsection (D)7 of this section.
Access: Access to aerobic treatment plants shall be adequate to allow maintenance and service of all components within the plant.
Operation Permit: Upon the installation of an approved aerobic treatment plant, the property owner shall secure an operation permit from the Building Officer at a fee to be established by the Village Board as a record and notice of the installation. The permit shall be in a form containing all pertinent information as to construction, installation and operation of the aerobic treatment plant. A copy of the permit shall be filed with the Village and the Illinois Department of Public Health and the County in which the plant is situated. This permit shall be annually renewed on the anniversary date of the installation for as long as an aerobic treatment plant is used in the private sewage disposal system for the dwelling. Failure to obtain or renew the permit shall constitute a violation of this title.
(J) Alternative Private Sewage Disposal System:
1.Aerobic Treatment Plants:
Aerobic Treatment Unit: After the effective date of this Code, aerobic treatment plants shall comply with the requirements of the National Sanitation Foundation (NSF) standard number 40, individual aerobic wastewater treatment, May 1983, and shall bear the NSF seal.

2.NSF Standard 350 certified system utilizing membrane technology. 
The designed rate of flow for each system shall be design per Section 905.2 (a) of the Illinois Administrative Code.
The systems will be required to be maintained and serviced per the manufacturers’ and NSF requirements for the life of the system.
If the system is designed for reuse of the treated effluent within a structure it shall be compliant with the Illinois Plumbing Code, the NSF Standard 350 and any local regulations.
If the system is to discharge to a subsurface dispersal area it shall be designed as follows:
The loading rate of the soils on each site shall be determined by using one of the following:
Double-ring infiltrometer to determine the Ksat value.  Depending on the types of soils present on the site ASTM D3385-09 shall be used to determine the Ksat value.  If the area for the subsurface dispersal area is in fill, a double-ring infiltrometer must be used to determine the Ksat value.  The Ksat value of greater than 5 shall use 5 as the Ksat.
