A. Aerobic Treatment Plant Approval. Aerobic treatment plants shall be tested and listed by NSF International or a laboratory approved by ANSI to determine compliance with the requirements of ANSI/NSF Standard 40, Residential Wastewater Treatment Systems, January 18, 1999. Standard 40 is a standard which covers an organized and coordinated system of components that functions to treat domestic sewage from individual residences. This Part shall allow approved aerobic treatment plants to serve a residential property which is occupied on a year-round or full time basis. Aerobic treatment plants shall not be used to serve a residential property which is used as a seasonal, weekend or part-time residence. Aerobic treatment plants considered for use to serve a non-residential property shall meet the requirements of Section 905.100J 1-3 of the Illinois Department of Public Private Sewage Code.
B. Class II Effluent. Aerobic treatment plants listed by NSF International or a laboratory approved by ANSI to determine compliance with ANSI/NSF Standard 40 for Class II effluent shall discharge to a subsurface seepage system designed and constructed in accordance with the requirements of § 8.04.420 – § 8.04.430 S.
C. Class I Effluent. Aerobic treatment plants listed by NSF International or a laboratory approved by ANSI to determine compliance with ANSI/NSF Standard 40 for Class I effluent shall discharge to a subsurface seepage field designed and constructed to be at least 2/3 the size determined necessary by estimated permeability.
D. Sizing Aerobic Treatment Plants. Aerobic treatment plants which are listed by NSF International or a laboratory approved by ANSI to determine compliance with ANSI/NSF Standard 40 as Class I and rated at 500 gallons per day will be allowed for the treatment of domestic sewage from residential property having up to and including 4 bedrooms. Other aerobic treatment plants that are listed by NSF International or a laboratory approved by ANSI to determine compliance with ANSI/NSF Standard 40 as Class I shall be sized as specified in Table VII (See Appendix B).
E. Installation. All components of aerobic treatment plants shall be installed at the time of the original installation.
F. Accessibility For Inspection and Maintenance. The plant shall be equipped with one or more grade-level access manholes located to permit periodic physical inspection and maintenance of all compartments and component parts. Component parts include submerged bearings, moving parts, tubes, intakes, slots, filters, and other devices. Grade level access manholes shall be installed in a manner to prohibit the entry of soil, water and dirt into the unit.
G. Effluent Standards are those currently enforced in the State of Illinois Private Sewage Disposal Licensing Act and Code.
H. Service Contract. A service contract shall be maintained on all aeration devices. All service shall be by a licensed private sewage disposal installation contractor who is familiar with the unit and utilizes manufacturer approved replacement parts.
I. Service Operation and Maintenance. Service operation and maintenance shall adhere to standards established by the Illinois Private Sewage Disposal Code.
J. Non-functional Aeration Units. If an aeration device is non-functional, the non-functional parts must be replaced so as to be maintained per the manufacturer's specifications. When the unit can no longer be maintained per the manufacturers specifications, the unit must be replaced with an approved Class I aeration device.
K. Non-Residential Properties. Any aeration treatment plant to service a non-residential facility shall maintain a registration with the Department, pay a registration fee and provide the required sampling data as detailed in the registration. Sampling data will include, but is not limited to daily flows, BOD-5 and suspended solids.
