Visual and tactile evaluation of two (2) or more soil profile test pit excavations must be conducted to determine soil type as well as to determine whether a limiting layer is encountered. 2. In addition to the two soil profile test pit excavations, percolation testing may be conducted to obtain additional information regarding the long-term acceptance rate of the soil. 3. If the site evaluation includes both a visual tactile evaluation of soil profile test pit excavations and percolation tests, and the results from these two evaluations do not coincide with the same LTAR as noted in Table 30-10-1, the designer must use the more restrictive LTAR in determining the size of the soil treatment area. B. Procedure for performing visual and tactile evaluations of soil in order to determine a long- term acceptance rate: 1. The soils evaluation shall be performed by or under the supervision of a professional engineer, professional geologist, competent technician, or other similarly qualified professional as approved by the Division. 2. Evaluation of two (2) or more soil profile test pit excavations must be performed to determine soil types, limiting layers, and best depth for the infiltrative surface. The total number of soil profile test pit excavations beyond the required two shall be based on the judgment of the competent technician. 3.

The minimum depth of the soil profile test pit excavation must be to any limiting layer, or four feet below the infiltrative surface of the in -situ soil, whichever is encountered first. 5. Layers and interfaces that interfere with the treatment and dispersal of effluent must be noted. Thus, any limiting soil characteristic such as consistence also needs to be evaluated. The evaluation of consistence may also include an evaluation of excavation difficulty, rupture resistance, and/or penetration resistance. 6. The soil observations must be conducted at or immediately adjacent to the location of the proposed soil treatment area, but if possible, not under the final location of a trench or bed. 7. Each soil profile test pit excavation observed at the proposed soil treatment area must be evaluated under adequate light conditions with the soil in an unfrozen state. 8. The soil observation method must allow observation of the different soil horizons that constitute the soil profile. 9. Soil profile test pit observations must be conducted prior to percolation tests to determine whether the soils are suitable to warrant percolation tests and, if suitable, at what depth percolation tests must be conducted. 10. The soil type at the proposed infiltrative surface of the soil treatment area or a more restrictive soil type within the treatment depth must be used to determine the long-term acceptance rate from Table 30-10-1 or Table 30-10-1A. The treatment depth is two to four feet depending on the required thickness for the treatment level below the infiltrative surface from Item 4, Table 30-7-2. 11. Soils data, previously collected by others at the site can be used for the purposes of an OWTS design at the discretion of the local public health agency. It is recommended that the data be verified, at a minimum, by performing an evaluation of a soil profile test pit excavation. C.

If a change of soil type, color or structure is present within those soils comprising the depth of soil below the infiltrative surface as required in Table 30-7-2 for vertical separation, a minimum of two (2) soil percolation holes must be terminated in the changed soil and percolation tests must be conducted in both holes. 5. Percolation tests. a. The percolation tests must be conducted using the hole preparation, soil saturation and rate measurement procedures described below. b. — No change. c. Presoak. 1) The hole must be presoaked adequately to accomplish both saturation, which is filling the void spaces between the soil particles, and swelling, which is the intrusion of water into the individual soil particles. 2) — No change. d. Percolation rate measurement. 1) With the exception of sandy soils containing five percent (5%) or less particles passing through the #200 sieve, by weight, percolation rate measurements must be made on the day following the presoak procedure. 2) If water remains in the percolation test hole after the swelling period, adjust the depth to approximately six (6) inches above the gravel in the bottom of the hole. From a fixed reference point, measure the drop in water level over thirty -minute intervals. The drops are used to calculate the percolation rate. 3) — No change. e. Sandy soils. 1) In sandy soils or other soils in which the first six (6) inches of water seeps out of the hole in less than thirty (30) minutes, after the twenty-four (24) hour swelling period, the time interval between measurements must be ten (10) minutes and the test conducted for one (1) hour. The drop that occurs during the final ten (10) minutes must be used to calculate the percolation rate. 2) If the soil is so sandy or coarse textured that it will not retain any water, then the infiltration rate must be recorded as less than one (1) minute per inch. f. Percolation rate determination and reporting. 1) The field percolation rate will be the average rate of the percolation rates determined for all percolation test holes observed in the proposed soil treatment area in minutes per inch. The average percolation rate determined by the tests must be used in determining the long-term acceptance rate for the proposed system from Table 30-10-1. 2) The technician performing the percolation tests shall furnish an accurate scale drawing, showing the location of the soil profile test pit excavations and/or percolation holes tied to lot corners or other permanent objects. The drawing must meet the criteria in Paragraph 30-5-60.A.7. All holes must be clearly labeled to relate to the information provided for the profile test pits and percolation tests.

When the infiltrative surface area of the media receiving wastewater effluent is at or above the natural ground surface at any point, it shall be considered a mound system. B. Mound systems that provide a minimum of 24 inches of sand treatment media may use the application rates for the in -situ receiving soil for TL1 effluent (Table 10-1). Size adjustment factors within Table 30-10-3 may be applied if TL1 application rates are used. C. Mound systems must conform to the design requirements of sections 30-11-30 C.1-5 for unlined (open bottom) sand filters, with the following exceptions. 1. A mound system may include less than 24 inches of imported sand media on a site where a lesser depth of sand media is sufficient to meet vertical separation requirements above a limiting layer. Application rates for the in -situ receiving soil for TL1 effluent must be used when less than 24 inches of sand media is used, unless higher level treatment is provided prior to dispersal into the mound system. 2. For the design of a mound system where less than 24 inches of sand media is proposed, and application rates for TL1 are used, the size adjustment factors within Table 30-10-3 may be used. D. The basal area must be determined using the LTAR from Table 30-10-1 for the in -situ receiving soil under the mound. E. Linear loading rates must be determined. The evaluation of many factors is required for an accurate determination of the linear loading rate. While application rates for the in -situ receiving soil under the mound is a main component, placement on the slope, and percent of the slope must also be addressed when defining the linear loading rate. If the movement of the effluent is primarily vertical, then the linear loading rate is not as critical. However, if the movement of the effluent will be primarily horizontal, as would be expected in soil types 3A through 5 (Table 30-10-1), then the linear loading rate is extremely important and long narrow mounds are strongly recommended. 1. When TL1 effluent is applied to the distribution media of a mound system installed above in -situ soil types 1 through 3 (Table 30-10-1) and R-0 through R-2 (Table 30-10-1A), the suggested linear loading rate is between 6 gpd/lin.ft. and 12 gpd/lin.ft. The maximum width of the distribution media in a mound system installed above these soil types is 12 feet when TL1 effluent is applied to the distribution media of a mound system. 2. When TL2 through 3N effluent is applied to the distribution media of a mound system installed above in -situ soil types 1 through 3 (Table 30-10-1) and R-0 through R-2 (Table 30-10-1A), the linear loading rate may exceed 12 gpd/lin.ft.; subsequently the mound may be wider than 12 feet. 3. When TL1 through TL3N effluent is applied to mound systems installed above in -situ soil types 3A through 5 (Table 30-10-1), the suggested linear loading rate is between 3 gpd/lin.ft. and 5 gpd/lin.ft. The maximum width of the distribution media in a mound system placed above these soil types is 12 feet. F. The final cover over a mound system must extend at least twelve inches horizontally beyond the perimeter of the distribution media prior to sloping down to existing grade. The final slope of the mound must be no greater than three feet horizontal to one foot vertical. G. The surface of the mounded area must be planted with a suitable vegetative cover. H. A suggested reference for the design and installation of mound systems is, "The Wisconsin Mound Soil Absorption System: Siting, Design, and Construction Manual, January 2000". Note that this is suggested guidance, and where the requirements of this regulation differ from those in the referenced mound document, the requirements of this regulation will govern in those cases.
