We are therefore requesting a permit be issued for the construction of a new septic system to serve the new home. The attached Site Plan and backup documentation identify the location and configuration of the new septic system and alternate site and the parameters used in the design. Also identified on the plans are the proposed water service line, test hole location and the locations of the facilities on the adjacent properties. Drainage arrows are also shown and current drainage patterns will be maintained stained after cvnstr uction. The test holes placed near the location of the proposed absorption trench indicated fine sand with a slight amount of silt to a depth of 6'. The sand below this level became well graded and contained substantial amounts of gravel. The new absorption trench will be placed in both soil strata and we have used an application rate of 1.2 gallons per day per square foot. No ground water was found and none was noted during the monitoring period. We are therefore proposing to construct a deep absorption trench system with a 35' long trench with an 8' effective depth. This length is approximately 3.75' longer than design requirements. The distribution piping depth will be 2' below the surface. Total depth of the trench will be 10'. The ground surface on the lot slopes at shallow grades from east to west. The absorption trench will be constructed parallel with the slope as much as possible in conformance with Municipal requirements. All components of the new septic system will be constructed a minimum of 10' from the water service line on the lot and on the adjacent lot. The system will also be constructed a minimum of 100' from any surface water in the area. If the system is constructed in accordance with our design the following statements apply: Lot 1, Block 4, Muirwood September 26, 2002 Page Two 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 subdivision is currently served by the Municipal water system. 2. 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. 3. 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. 4. 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, 'J'kj f' a"�" Michael E.

The scope of this project includes the procurement and placement of a new 1,250 -gallon septic tank at the location shown on the site plan and the construction of a new 35' long by 3' wide by 8' effective depth absorption trench also shown on the Site Plan. The total depth of the trench will be 10' below existing ground and the distribution pipe will be placed at 2' below the surface. All components of the septic tank and absorption trench must be constructed a minimum of 10' from the water service to be constructed on the lot. A minimum of 4' of fill must be placed atop the septic tank and 3' of fill above the absorption trenches. In lieu of fill 2" of direct bury insulation may be placed with 2' of fill atop the insulation. 2. Construction shall be in accordance with the approved site plan, design drawings, Municipal Permit with any special provisions or, conditions, and all applicable State and Municipal Wastewater Disposal Regulations. 3. The Contractor shall be responsible for obtaining all underground utility locates and for the layout of the septic system and verification of the location of all lot lines. 4. Unless specifically agreed otherwise, the contractor shall be responsible for final grading areas subsequently depressed from soil settling. Property owner shall be responsible for revegetation of affected areas unless specifically agreed otherwise. 5. Contractors installing wastewater disposal systems must be certified by the Municipal Department of Health and Human Services for system installations. Owners installing their own systems must receive prior approval from D.H.H.S. before beginning system installation. SEPTIC TANK INSTALLATION 1. The 1,250 -gallon septic tank must be procured from an approved septic tank manufacturer and installed at the location shown. 2.
