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 85.30(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 0.20 gpd/sf, and the linear loading rate 4.5 gpd/ft. 4. Chisel plowing to a depth of 12-16 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 (see recommendation by CST) 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. 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. 7. 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. 8. 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. 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 plans for the design, not to the decision on the Interpretive Determination Report. r SHAUN R BIRD Page 2 12/2/2005 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 jn lieu of additional full plan sets, 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. As per state stats 101.12(2), nothing in this review shall relieve the designer of the responsibility for designing a safe building, structure, or component.

DIV SION OF SAFETY AND BUILDINGS SEE RRES NDEN y Soiil Series- and Mapping Units- The St. Croix CountySoil Survey has-mapped this area as being of F'reeon soil series, which-consisis-of gently sloping, moderately well-drained soils. These soils are on low ridges and foot slopes of ground- momines. They formed in silty sediment and the underlying, reddish sandy loam till. The FnB soils of this series are representative as described by the Soil- Survey and are represented-by, a surface layer that is approximately 8 inches of dark grayish brown silt loam. The subsurface layeris brown silt loam and about 10 inches thick. The subsoil-is about 16 inches thick.

Worm- activity was recognized at a depth of l I inches in boring 1 and at a-depth of 1-0-inches in- boring two. Root activity was observed at 13 inches on boring 1, 14 inches on boring 2-, and 14 inches on boring 3. It is recognized that these biological activities are normally not apparent in zones that are saturated for long periods-of time. This-being a first year crop (winter-wheat) and a very wet spring these factors fiuthersupport-the suggestion that this portion of the profile dries quickly after a precipitation event: The three borings observed all had redox features between 4 to 8 inches in the 10yr3/3 silt loam and had ~ r redox- free soilsbelow from- 8 to 1-finches. in the sandy clay loams before-redox- features once again- c , t',~C ~.s ~ appeared-. Recommen&tions The recommendation for the site would be for the site to be chisel plowed to a depth of at least 1-5 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 placid on the plowed area: This-provides the-36 inches of vertical- separation to-provide-the treatment of pathogenic- Organisms. The recommended-mound design-uses &linear loading rate of 4.5-gpd/#f-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 mz 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: ➢ The described soils in this location supports some the mapped description, which represents in its description more sandy clay loams and silty clay in the substratum. The platy soils located at depths of 4 to 8 inches are probably due to farming practices and can be over come by the deep chisel plowing so as to reorient the clay particles in a more vertical orientation. ➢ 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. ➢ 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/ft2t. 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 tlf 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. The month of May and early June had a great number of rain event days and even with this unusual amount of precipitation the holes had no free water. Additionally, the redox features that were observed were progressively more intense deeper in the soils profile suggesting that the upper levels were redox features were observed were not saturated for as long of periods of time. 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 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.

Collova Site Two other hand borings on Lot 15 revealed similar conditions. Redox features were observed in the A horizon and in the subsoil below. If mound systems are designed to overcome limitations of a high level of seasonal soil saturation and slow permeability, the linear loading rate should not exceed 4.5 gpd/ft and the basal wastewater application rated should not exceed 0.2 gpd/ft2. 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 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. Deep chisel plowing may be needed to improve the permeability where a plow pan appears to restrict downward water movement. Special Comments: 1. The down slope toe of the proposed mound area on Lot 5 should be well clear of the drainage way. Soil conditions near the drainage way are very marginal for proper dispersal of effluent from a mound system immediately up slope. It is recommended that the proposed mound area be moved approximately 50 feet up slope. Property line boundaries would have to be reconfigured or an easement granted for placement of the mound on Lot 4. Soil tests would need to be redone to verify suitable conditions in the new area. 2. Even though I specified the maximum linear loading to be 4.5 gpd/ft, designers should try to design systems at 3.5 to 4.0 gpd/ft if possible. 3. Two soil borings in the proposed mound area on Lot 15 exhibited redox concentrations in the lower part of the A horizon and immediately below in the subsoil. This area is somewhat more level than other areas and more precipitation may infiltrate than on a sloping site. In addition, agricultural practices may have caused some compaction in the lower part of the A horizon and upper part of the B horizon. The combination of more infiltration and weak soil compaction may result in a higher level of saturation at this site than at other areas of the plat. Options include moving to another area on the lot, monitoring the area with observation pipes this next spring [see Comm 85.60(3) for requirements], or compiling a convincing explanation of why this is occurring and why it's not a problem for proper system operation.

C. Collova Builders PO Box 489 Wastewater Flow: 450 gpd Somerset WI 54025 Persons Present: S. Bird, P. Quinn 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. Soil samples were taken from the approximate midpoint in the staked mound areas and reviewed under florescent fight at my office. Typical soil profiles could be described as follows: Lot 5 00-04" 10YR 3/2 sil, 2msbk, mfr, as. 04-07" 10YR 3/3 sil, 1 mpl, mfr, as. .07-09" 10YR 4/4 cl, 1 mpl, mfr, cw. 09-12 10YR 4/4 cl, 1 csbk, mfr, with f2f 10YR 5/6 rmfs.

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 water around the mound structure as much as possible. In addition, an up slope drainage ditch should be considered if it is Page 2 of 2 November 29, 2004',-4 P.C. Collova:SiteA A. determined that.surface, ovaUbsurface hydrology is improved by intercepting water and diverting it away from the mound site. Special Comments: 1. The down slope toe of the proposed mound area on Lot 5 is very close to a drainage way. Soil conditions in this area are very marginal for proper dispersal of effluent from a mound system immediately up slope. It is recommended that the proposed mound area be moved approximately. 50 feet up slope. Property line boundaries would have to be reconfigured or an easement granted for placement of the mound on Lot 4. Soil tests would need to be redone to verify suitable conditions in the new area. 2. Even though I specified the maximum linear loading to be 4.5 gpd/ft, designers should try to design systems at 3.5 to 4.0 gpd/ft. .3. Two soil borings in the proposed mound area on Lot 15 exhibited redox concentrations in the lower part of the A horizon. This area Is somewhat more level than other areas and more precipitation may infiltrate than on a sloping site. In addition, agricultural practices may have caused some compaction in the lower part of the A horizon and upper part of the. B horizon. The combination of more infiltration and weak soil compaction may result in a higher level of saturation at this site than at other areas of the plat. Options include moving.to another area on the lot, monitoring the area with observation pipes this next spring [see Comm 85.60(3) for requirements], or compiling a convincing explanation of why this is occurring and why it's not a problem.for proper system operation.
