NW 1/4, SW 1/4, S34, T28N, R18W FOR: Object Type: Soil Saturation Determination Regulated Object ID No.: 1081215 The submittal described above has been reviewed for conformance with applicable Wisconsin Administrative Codes and Wisconsin Statutes. The submittal has been CONDITIONALLY APPROVED. The owner, as defined in chapter 101.01(10), Wisconsin Statutes, is responsible for compliance with all code requirements. The following conditions shall be met during construction or installation and prior to occupancy or use: 1. Approval is hereby granted pursuant to s. Comm 85.60(2), Wis. Adm. Code, to estimate the depth to seasonal soil saturation based on an interpretive determination process. Approval of the interpretive determination negates the - -requirement in-s:-Comm-8 .30(-2-b),Wis--Adm:-Code-to designate- -the-ground_surface-as the highest level of soil saturation when redoximorphic features are less than 4 inches below the bottom of the A horizon. 2. The estimated highest level of prolonged soil saturation approved under this determination is 6 inches below grade. At least 30 inches of sand lift on top of 6 inches of unsaturated, in-situ soil is required for adequate treatment and dispersal. 3. The basal soil application rate for the mound shall be :S 0.20 gpd/sf, and the linear loading rate < 4.5 gpd/ft. 4. Chisel plowing to a depth of> 15 inches immediately prior to sand placement is required to improve vertical water movement into the soil solum. 5. Landscaping up slope of the mound shall be incorporated into the POWTS design to prevent surface water from concentrating along the up slope edge of the mound and to divert surface water drainage away from the system. 6. The down slope toe shall have a slope ration of at least 4:1 and the upslope toe at a point L/2 must have a 6:1 slope ration applied. The upslope slope ratio at the ends of the should be 3:1. These design criteria will create a condition where surface water cannot pond up slope and behind the mound. 7. This approval shall remain valid unless the site is altered in such a way that the depth to soil saturation would change or if saturated conditions are observed for seven consecutive days at depths less than 3 feet below the infiltrative surface of the POWTS distribution component. 8. This approval in no way relinquishes the use of color patterns to estimate the depth to high groundwater on any other parcels or portions of parcels. 9. A copy of this approval letter and attachments must accompany the mound system design for this site for purposes of plan approval and sanitary permit issuance. THOMAS C NELSON Page 2 6/20/2'06 If the Interpretive Determination Report was accompanied with a plan and an expiration date is shown on this letter, the expiration date only applies to the plane for the design, not to the decision on the Interpretive Determination Report. A copy of the approved plans, specifications and this letter shall be on-site during construction and open to inspection by authorized representatives of the Department, which may include local inspectors. If plan index sheets were submitted in lieu of additional full plansets, a copy of this approval letter and index sheet shall be attached to plans that correspond with the copy on file with the Department. All permits required by the state or the local municipality shall be obtained prior to commencement of construction/installation/operation. If this construction project will disturb one or more acres of land, an Erosion Control Notice of Intent (NOI) shall be filed with the department 14 days prior to any earth disturbing activities. In granting this approval the Division of Safety & Buildings reserves the right to require changes or additions should conditions arise making them necessary for code compliance.

This investigation revealed t e so s weV09= for an A+0 mound system through an interpretive determination as designa t Of Commerce's Administrative Code, Comm 85. DEPARTMENT OF COMMERCE DIVI 'ION OF SAFETY AND BUILDINGS Methodology: Backhoe pits were provided for three borings, 1 through 3, with interpreons o e si~esCsw i i~'y-bein conducted by using soil redoximorphic features, soil texture, soil structure, soil color pursuant to the guidelines under Chapter Comm 85 of the Wisconsin Administrative Code and using the USDA-NRCS soil descriptive system. During this field investigation the landscapes morphological features, vegetation, and hydrology was determined for the purpose of this Interpretive Determination as defined in Comm 85.60(2) of the Wisconsin Administrative Code. Upon completion of the collected field data, which included the accurate measurement of the sites featured parameters, site plans, system design, and this interpretive report have been developed for review. The intent is to demonstrate that a minimum of 6 inches of unsaturated soil exists on this site and any influencing factors on this would allow the compliant installation of a mound system serving a residential use for this property as allowed under Comm 83.44(3)(b) of the Wisconsin Administrative Code. Local Hydrology: The local hydrology of this site is influenced by the average of 30 inches of precipitation received. The soil properties and localized topography both influence water movement on this property. Seasonal issues such as frozen ground and warm temperatures also have their influences during the winter months when the ground is frozen, there would be an accumulation of snow with any melting action running off the site on the surface of the ground. Spring rains would produce additional surface runoff until the ground has thawed. Upon thawing, the influence on groundwater levels would be minimal due to the location of the site with its limited upslope watershed. The 5 percent surface slope would also aid the slower permeability of the soils. Summer temperatures and plant growth would provide removal of soil moisture through evaporation and evapotranspiration. Local Geomorphology, Soil Disturbance, and Local Topography The geologic interpretation of this area directly related to the glacial geology of the Eastern St. Croix Moraine, a ground moraine that was formed by the accumulation beneath the glacier and resulted in a composition of stony, reddish-brown glacial drift. Post-glacial windblown silts formed loess deposits that overlays this till. Below is the Cambrian bedrock Prairie Du Chien formation, a dolitimized limestone formation. Soil forming activities have resulted in what is known as the Northern Till Uplands soils resulting in dark silty soils. The site was probably originally in crop production in previous years. However, at the time of this determination it was grass. This hillside has a 5 percent slopes and was probably formed as the advancing ice scoured the landscape, retreated, depositing the till material, forming the rounded knobs of the hillside. Soil Series and Mapping Units The St. Croix County Soil Survey has mapped this area as being of Derinda Variant silt loam soil series, which consists of gently sloping, somewhat poorly drained soils. These soils are on low ridges and foot slopes of ground moraines. They formed in silty sediment and the underlying silty clay weathered from shale. The DfB soils of this series are representative as described by the Soil Survey and are represented by a surface layer that is approximately 9 inches of very dark gray silt loam. The subsurface layer is dark grayish brown mottled silt loam and about 5 inches thick. The subsoil is about 16 inches thick. The upper part is brown, mottled, firm silt loam; the lower part is a olive and olive gray, very firm, mottled silty clay. The substratum, to a depth of 60 inches, is olive gray and pale green clay shale. There are limestone fragments in the shale. Data ➢ The soils evaluation report and system design have been included with this report. ➢ A copy of the USDA Soil Survey map that provides the soil-mapping unit described above. A USGS Topographic Map, revealing the topography of the site. ➢ POWT site plan, representing the best location and layout of the system that best treats and distributes the systems discharge water. Government Reports Leroy Jansky, Wisconsin Department of Commerce Wastewater Specialist has visited the property, and a report has been filed. Additional Information Unique to the site During the evaluation there was the observation of biological activity in the form of worm burrows and roots. Worm activity was recognized at a depth of 8 inches in boring 2 and at a depth of 9 inches in boring two. Root activity was observed at 14 inches on boring 1, 13 inches on boring 2,15 inches in boring 3. It is recognized that these biological activities are normally not apparent in zones that are saturated for long periods of time. These factors further support the suggestion that this portion of the profile dries quickly after a precipitation event. Recommendations The recommendation for the site would be for the site to be chisel plowed to a depth of at least 15 inches so as to breakup the soil interface and reorient the platy structure in a more vertical position, thus aiding infiltration. From the upside slope of the system area, 30 inches of ASTM C-33 sand lift will be placed on the plowed area. This provides the 36 inches of vertical separation to provide the treatment of pathogenic organisms. The recommended mound design uses a linear loading rate of 4.5 gpd/ft and an in-situ soil application rate of 0.2gpd/ft . This will be accomplished by designing the absorption area to be long and narrow and extended the down slope toe area to a 4:1 dimension, effectively increasing the basal area and eliminating the chances of toe seepage. Additionally, the slope on the upper toe edge of the mound will be constructed so as to be a slope with a 3:1 side slope at each end and a 6:1 side slope for the I dimension (upper slope) at a point L/2 (this being the location at half the distance of the total length of the mound) so as to help divert surface water from the upper slope (See included suggested mound detail plan). Finally the design requires that a water diversion ditch be installed above the mound so as to divert surface waters from the upslope area This should be installed with a 5:1 slope, a width of eleven feet, and oriented so that it traverses the contour slightly, draining the run off water north and down slope of the mound area. Conclusions It is my belief that the soils in the area of the proposed POWS will not be saturated above 6" for seven or more consecutive days for the following reasons: r The described soils at this location supports the mapped description, however, the depth of redux features was observed lower in the profile than described by the soil survey. ➢ The biological activity in the soil as represented by the roots and Earth Worm presence, suggest that the soil has not been saturated in the most recent history of the soils. These activities cannot survive in saturated conditions. Y A design with a long and narrow system representing a linear loading rate of 4.5 gallons per day per foot and an in-site soil application rate of .0.2gpd/ft`t. This configuration represents the best distribution of the wastewater, spreading it over a longer area. With the increased height of the mound, there is the assurance that there will be 3 feet of filtration between the bottom of the system and the zone of saturation. Also built into the plan is the increased dimension of the upslope of the mound, providing a 6:1 slope at the L/2 location, and the addition of a drainage ditch above the mound. These last two additional features will minimize surface runoff onto the mound area from higher elevations behind the system. The total design assures that the requirements of Comm. 83.41 of the Wisconsin Administrative Code are being met so as to properly filter the wastewater and to assure that there is no surface discharge, with discharge going below grade. ➢ The mound septic design and management plan provides proper treatment of wastewater and expected system longevity. Accordingly, the plan submittal addresses the methods and design for treatment and dispersal of the wastewater below the surface as addressed by the code requirements. Y In each pit that was dug the prominence and size of RWS increases with depth suggesting that the lower horizons are more saturated for a longer period of time. The second horizon in each pit while being saturated for a given period, are not as saturated as the horizons below. ➢ The matric colors of the soil chances from 10yr3/2 to 10yr4/3 and 5yr5/3 as you co lower in the soil profile suggesting more saturated conditions lower in the profile. The final authority for this site's approval rests with the appropriate regulatory agencies: the Wisconsin Department of Commerce and the St. Croix County Zoning officials.

Nelson, P. Quinn, River Falls, WI 54022 Owner An onsite soils verification was conducted at the above referenced site as per district policy for all sites with less than four inches of unsaturated soil below the bottom of the A horizon. The intent of this investigation is to confirm initial observations by the certified soil tester (CST) relating to the presence or absence of redoximorphic features in the A horizon and/or subsoil. In-situ soil texture, structure, and consistence factors were also reviewed as they relate to wastewater application rates. Other site conditions such as percent and direction of slope, landscape position, land surface contour length, and surface water hydrology may also be noted and their effects are factors considered in the recommendations and conclusions portion of this report. Several lots were reviewed for potential interpretative determinations. A typical soil profile may be described as follows: Lot 3 Near CST B-1, B-3 Frozen Soil boring 1 has a thick A horizon and 5Y 5/4 c immediately below the A horizon. Lot 4 Near CST B-1 00-08" 10YR 2/2 sil, 1 csbk, mfr, aw. 08-10" 10YR 2/2 sil, 1 msbk, mfr, as. 10-14" 10YR 4/4 sil, 2msbk, mfr, cw, w/ f2f 10YR 4/6 rmfs, few 10YR 6/3 silt coatings on ped surfaces. 14-21" 10YR 4/4 sicl,. 2msbk, mfr, c2f-d 10YR 4/6 and 5/2 rmfs few 10YR 6/3 silt coatings. Lot 5 In Area of Soil Test This area has similar soil conditions as Lot 4. It is my opinion that soil conditions at Lot 3 would be difficult to justify as suitable without direct observation of seasonal high water levels. Therefore, it is recommended that soil saturation monitoring (groundwater level monitoring) be conducted pursuant to Comm 85.60(3), Wis. Adm. Code, to establish the highest level of seasonal soils saturation. If a mound system is designed to overcome limitations of a high level of seasonal soil saturation and slow permeability on lots 4 and 5, the linear loading rate should not exceed 4.5 gpd/ft and the basal wastewater application rated should not exceed 0.2 gpd/ftz. The additional basal area will partially compensate for the gentle land slope and prevent wastewater leakage at the mound toe. At least 30 inches of sand lift is recommended when applying septic tank effluent to the distribution cell of the mound to ensure proper treatment. The longest portion of the mound must be orientated along the contour. The mound shall be constructed to divert surface Page 2 December 13, 2005 Lee Site water around the mound structure as much as possible. In addition, an up slope drainage ditch should be considered if it is determined that surface or subsurface hydrology is improved by intercepting water and diverting it away from the mound site. I, If there are any questions regarding this report, -please contact me.
