We are therefore requesting a permit be issued for the construction of a new well and septic system to accommodate the home. The attached Site Plan and backup documentation identify the location and configuration of the proposed well and septic system along with the alternate site. Also identified on the plans are the existing wells and septic systems on surrounding lots. No conflicts exist between the proposed well and septic system and wells or septic systems on adjacent lots. Drainage arrows are shown on the site plan showing the grade and direction of flow on the lot. The drainage pattern will not be changed as a result of this project. The test holes recently placed on the lot in the area of the absorption trench and alternate site indicate poorly graded to silty gravel (GM/GP). The percolation rate of the soil was determined to be 2 to 3 minutes per inch. Siltier material was found at the 7' level which percolated at 44 minutes per inch. No groundwater was found during the placement of the test holes and none was noted during the monitoring period. An application rate of 1.2 gallons per day per square foot was used in the design of the absorption system. We are proposing to place a new 1,500-gallon septic tank and 2 new 37' long by 5' wide by 3' effective depth absorption trenches to treat and dispose of the effluent generated in the house. The elevation of the distribution line in the absorption trench will be 2.0' below the surface and the total .depth will be 5.0'. A minimum of 3' of fill or 2" of insulation and 2' of fill will be placed over the absorption trench and 4' over the septic tank. A flow splitter valve will be placed to assure even flow to each trench. The ground surface on the lot in the area of the septic system slopes to the north at approximately 6%. The new trenches will be constructed parallel with the slope as much as possible in conformance with Municipal requirements. The new septic system Lot 14, Block 3, McMahon Subdivision June 29, 2010 Page Two will be constructed a minimum of 100' from all wells and any surface water and 10' the proposed and existing water services in the area. If the system is constructed in accordance with our design the following statements apply: The system, if constructed as designed, will have no adverse impact on the wells in the area or those to be constructed in the future. The system, if constructed as designed, will have no adverse impact on existing septic systems in the area or those to be constructed in the future. The system, if constructed as designed, will have no adverse impact on reserve space, either surface or subsurface, on any lots located in the area. The system, if constructed as designed, will have no adverse impact on drainage patterns in the area. The current drainage pattern will be maintained. Sincerely, Michael E. Anderson, P.E.

This inspection revealed a nitrate concentration of 8.43 milligrams per liter (mg/L) was reported for the property's well water sample. The Environmental Protection Agency (EPA) has established a maximum contaminant level (MCL) of 10.0 mg/L for public drinking water systems. While private wells are not subject to this regulation, EPA standards are based on existing health information and can therefore be used to gauge the relative quality of water from private wells. Please see the attached "Nitrate Fact Sheet" for important information regarding nitrate. This advisory must be attached to all copies of the subject Certificate of On- Site Systems Approval.
