After January 1, 2014, when designing a subsurface seepage system, the absorption capacity of the soil shall be determined by subsection (a). After January 1, 2014, subsection (b) shall not be used to determine design requirements for a subsurface system.

 

a)         Soil Investigation

 

1)         Soil investigations shall be conducted in the following manner:

 

A)        Determination of soil characteristics on sites proposed for development with private sewage disposal systems shall be based on soil boring data collected by a soil classifier or an Illinois licensed Professional Engineer.

 

B)        There shall be a minimum of 3 borings per soil absorption system site.  The soil borings shall be at least 50 feet apart, and the proposed subsurface seepage system shall be located within the area where the soil borings were located.  More soil borings may be necessary for accurate and appropriate evaluation of a site where there is some concern about the consistency of the soil materials.  One of the borings shall be made at the lowest elevation of the proposed absorption field area.  Borings shall extend a minimum of 60 inches below the natural ground surface.  An observation pit shall be used in gravelly materials.

 

C)        Observation and determination of soil characteristics may also be determined from a pit dug by a backhoe or other excavating equipment.  The Department or local authority may require soil pits (backhoe excavation) in cases where ground is frozen, where the soil materials are considerably varied in texture, where there has been previous or current fill material or cutting of soils, or where gravelly soils are encountered.  Soil pits shall be prepared at the perimeter of the expected soil absorption area to minimize damage to natural soil structure.  Soil pits shall extend a minimum of 60 inches below the natural ground surface.

 

D)        Site characteristics to be described include zones of seasonal and permanent water saturation, United States Department of Agriculture (USDA) soil textural changes; USDA soil structural features for each horizon, slope, compaction and depth; soil coloration; consistence; coatings; depth of limiting layer; depth of soil mottling; internal drainage classification; permeability range; and other limiting soil characteristics that may reduce permeability. The following reference materials shall be used as a guide for describing and classifying soil: Field Book for Describing and Sampling Soils, Soil Taxonomy, and Soil Survey Manual.

 

2)         The following persons are qualified to conduct soil investigations:

 

A)        any person who meets the definition of soil classifier in Section 905.10;

 

B)        an Illinois licensed Professional Engineer;

 

C)        an employee of a local health department who has 3 years of experience in designing or approving private sewage disposal systems using soil classification information and 6 semester hours of soils-related coursework;

Section 905.60  Subsurface Seepage System Construction Requirements

 

a)         Seepage Field Requirements – Gravel, Gravelless and Chamber Systems.  Subsurface seepage fields shall be designed and constructed in accordance with Appendix A, Illustrations H, I and J and the following:

 

1)         All subsurface seepage systems using soils information for sizing shall use the soil suitability table in Appendix A, Illustration M to determine the size requirements of the subsurface seepage system.  The least permeable soil layer between the top of the gravel or gravelless pipe or chamber system and 2 feet below the bottom of the trench shall be used to determine the size of the subsurface seepage system. For mound or at-grade systems, the least permeable soil layer in the upper 2 feet of the soil shall be used to determine system size.

 

2)         The bottom of the subsurface seepage field, each trench and its distribution line shall be level.  Level for this Part shall mean plus or minus ½ inch in any direction over the entire area of the subsurface seepage system.

 

3)         There shall be a minimum of 6 inches and a maximum of 24 inches of earth backfill over the bedding materials, gravelless pipe or chamber system.

 

4)         There shall be a minimum of 5 feet of undisturbed earth between the septic tank and the nearest trench.

 

5)         If precipitation falls onto the excavation and evidence of soil washing into the excavation of the subsurface seepage system exists, the damaged portion of the seepage system shall be reconstructed to comply with this Section.

 

6)         The top of the gravel, gravelless pipe, or chamber system in the subsurface seepage field shall be at least one inch below the invert of the outlet pipe from the septic tank or distribution box in a gravity flow system.

 

7)         Site Evaluation for Subsurface Seepage Systems.  Subsurface seepage systems receiving septic tank effluent shall have at least 2 feet of vertical separation distance between the bottom of the subsurface seepage system and the top of the limiting layer.  For soils in Design Group I-VI or with a loading rate of greater than 0.62 gallons per day per square foot, there shall be at least a vertical separation distance of 3 feet between the bottom of the subsurface seepage system and the top of the limiting layer. When the limiting layer is the estimated seasonal high water table, artificial drains, which are designed to lower the estimated seasonal high water table, may be installed to achieve the specified vertical separation distances.

 

8)         Sizing of a Seepage System in Fill Soil

 

A)        The least permeable soil layer between the top of the gravel, gravelless pipe or chamber system and 2 feet below the bottom of the trench shall be used to determine the size of the subsurface seepage system.

 

B)        The use of fill for installing subsurface seepage systems shall not be approved for lots platted after March 15, 1996.

 

C)        Fill soils may be used to cover a private sewage disposal system, provided that no part of the system is located in the fill and the fill material is at least equal to or better than the original soil or meets the requirements in subsection (a)(9).

 

9)         Soil Criteria for Use of Fill in Subsurface Seepage Systems

 

A)        Soils to be used for fill shall be identified by a soil classifier or licensed Professional Engineer and a report submitted to the Department or local authority.  The report shall contain specific information on the fill soil, including location, depth, permeability, and texture.  Soils that can be used as fill are those identified in Appendix A, Illustration M as 2A, 2B, 2K, 3A, 3B, 3C, 3K, 3L, 4B, 4D and 4K (Design Group II, III and IV).

 

B)        In addition to the requirements in subsection (a)(9)(A), fill soil shall not contain extraneous material such as tires, concrete, brick, reinforcing bar, demolition material, etc.

 

C)        All of the following conditions shall be met for a subsurface seepage system to be installed in fill.

 

i)          Satisfactory original soil shall be at least 3 feet above bedrock.

 

ii)         A maximum of 2 feet of fill soil shall be used.

 

iii)        Fill shall not be placed on original soil with a slope greater than 10%.

 

iv)        The fill shall be placed at the site so that a minimum of compaction occurs, and the fill shall be allowed to settle undisturbed for a period of at least 12 months.  Soils in Design Group II, when used for fill, shall not be required to settle for a period of at least 12 months.

 

v)         After the fill has been settled, a percolation test shall be conducted in accordance with the procedure outlined in Appendix A, Illustration G and a percolation rate of not greater than 270 minutes/6 inch fall or less than 60 minutes/6 inch fall shall be achieved.

 

10)         Site Preparation for Use of Fill Soil

 

A)        Excess vegetation shall be cut and removed.  The site shall be plowed with a mold board plow 7 to 8 inches deep with the plowing done perpendicular to the slope.  It shall not be done with the furrow running up and down the slope. Chisel plowing may be used in place of mold board.  Roto-tilling is prohibited.

 

B)        Once the site is plowed, all traffic shall be kept off the site.  The fill material can be deposited on the top with a backhoe or pushed on from the side, preferably the upslope side, using a track type tractor, keeping 6 inches of fill beneath the tracks.  At no time shall ruts be made in the plowed area.  The fill shall be placed immediately after site preparation to avoid the possibility of precipitation falling on the plowed area.

 

C)        Traffic on the downslope side of the fill area shall be minimal to reduce compaction.  All work shall be performed from the ends and upslope side. Compaction of the natural soil downslope will reduce the lateral movement of the effluent.

 

D)        The fill shall not be placed on frozen ground or when the soil is wet. Moisture content of the soil is very important when filling.  Site preparation shall not take place when the soil is too wet.  To check moisture content, a soil sample may be taken from the plow layer (7 to 8 inches) and rolled between the palms of the hands.  If the soil rolls into a ribbon, it is too wet to prepare.  If the soil crumbles, site preparation can then proceed.

 

b)         Gravel Seepage Field Requirements

 

1)         Bedding Material.  The bedding material shall be clean gravel or clean stone that is free of mud, silt, or clay, with particle size ranging from ¾ inch minimum to 4 inches maximum.  The bedding material shall extend the full width of the trench and to a depth of at least 6 inches below the bottom of the distribution line.  The bedding material shall extend at least 2 inches above the top of the distribution line.

 

2)         Distribution Lines.  Distribution lines shall be constructed of materials as approved in Section 905.20(f).  The lines shall be perforated or open-joint tile.  Where open joint tile is used, the tile sections shall be spaced not less than ¼ inch or more than ½ inch apart.  Perforated piping with the exception of 8-inch or 10-inch gravelless seepage beds shall have ½- to ¾- inch diameter openings on 3- to 5-inch centers with a minimum of 2 rows. The openings in the pipe shall be placed downward.

 

3)         Separation Material.  Bedding materials shall be covered by straw, newspaper, untreated building paper, geotextile fabric or other permeable or biodegradable material to support the backfill as the laying of the distribution line proceeds.  Tar paper, plastic, or other impervious material shall not be used between the bedding material and the earth backfill.

 

4)         The ends of a gravel seepage field shall be looped except in serial distribution systems.

Section 905.205  Civil Penalties and Time Allowances for Corrective Action

 

a)         Amount of Penalty

 

1)         The Department may assess civil fines against any person or licensee who constructs, installs, repairs, modifies, maintains or fails to provide for required maintenance of a private sewage disposal system, or any person or licensee who pumps, hauls or disposes of wastes from a private sewage disposal system in violation of any Section of the Act or this Part.

 

2)         The Department shall determine the amount of the fine based upon the seriousness of the violation. The seriousness of the violation will be determined as  follows:

 

A)        Type A – violations considered the most grievous, which shall be grounds to assess a larger fine, shall be activities that create a health  hazard, unlicensed activities and repeat violations. Examples of these activities include violations of vertical or horizontal separation distances, falsifying information on permits or reports, addition of prohibited materials to a private sewage disposal system, use of improper septage disposal methods and prohibited discharges. The amount of the fine shall not exceed $1,000 for each violation in addition to $100 per day for each day the violation continues.

 

B)        Type B – violations relating to improper construction practices, the use of improper materials, failure to install a system according to the approved plan, any violation of Section 905.135 and pumper equipment violations shall be considered more serious. The maximum fine shall not exceed $750 for each violation in addition to $100 per day for each day the violation continues.

 

C)        Type C – administrative violations involving paperwork, such as failure to obtain a permit or improper pumping truck lettering, shall be considered the least serious. The maximum fine shall not exceed $500 for each violation, in addition to $100 per day for each day the violation continues.

 

D)        For the purposes of determining a repeat violation, an initial violation means the first violation of a particular Section of the Act or this Part within the previous 3 years.  An identical or similar violation (example: a violation of vertical or horizontal separation distance or septage disposal) that occurs within a 3 year period will be considered a repeat violation.

 

b)         Correction of Violation.  Correction of violations that are considered serious health hazards as determined by the Department or local health department shall begin immediately and  be completed within 7 days.  Other violations shall be corrected within 30 days after notification by the Department or the local health department.  An exception to this requirement may be authorized by the  Department or local health department when extenuating circumstances prevent correction in a timely manner.  Examples of extenuating circumstances include weather, physical conditions that prevent construction or repair, or lack of adequate materials.  The Department or local health department may also grant an extension of time for correction, based on the type and seriousness of the violation and the violator's demonstrated progress in correcting the violation.
