We are submitting this permit applicationf orthe constructionof a new well and septic system The attached site plan identifies the location of the home as well as the proposed well, septic location and alternate site. The existing system will be abandoned. No conflicts exist between this proposed system and any wells, whether on this lot or adjacent lots. Contours are shown on the site plan showing the grade and direction of flow. The drainage pattern in general will not be changed by the construction. Test Hole # 1, placed on the lot where the system will be installed, indicates silty gravel (GM) to at least 8'. Percolation test results indicated an absorption rate of just over 15 min/in. On the northern side of the lot, the soils became closer to clay and did not perk, as documented in Test Hole #2. Groundwater was measuredto be at 2.5' atthe seasonal highlevel. CategoryIII Advantex system will be placed on this lot. An application rate of 4.0 gpd/sfwas used in the design of the absorption system. Although the current home is a 2 -bedroom home, we are designing a system with a 3 -bedroom capacity. We are proposing to place a new 1500 -gallon Advantex tank with one AX -20 pod anda shallowabsorptiontrench5' wide x 25' longx 0.5' effective depth. The elevation of the distribution line will be at existing grade with a total depth of 0.5' below grade. This will allow for a 2' separation from the seasonal high groundwater level, appropriate for a Category III system. Soil will be mounded 2' above the trench with insulation. All organics will be removed below the bottom of the trench and replaced with MOA -approved filter sand. The ground surface on the lot slopes only moderately on the property, with no area sloping more than 20%. The new septic sy stemwill be placed in the flatterarea south of the new home. The new trench will be constructed parallel to the slope as much as possible. Due to the MOA -mapped wetlands that extend onto the property, the orientation of the trench will not exactly match the contours. However, the trench will be basically perpendicular to the slope, and care will be taken to ensure thatit is builtperf ectlyflat. It will be a minimumof 50' from all wells and surface water, and more than 5' away from the septic tank. The alternate site is located more than 10' away. If the system is constructed as designed, it will have no adverse impact: • On the wells in the area or those to be constructed in the future. On existing septic systems in the area or those to be constructed in the future. On reserve space on any lots located in the area. On drainage patterns in the area. The current drainage pattern will be maintained. Sincerely, nXN Benjamin Schiller, PE/ * Q IN *� •.. .. ...... I% • • •.
