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 septic system along with the alternate site. No existing wells are closer than 100' from the proposed septic system. 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 placed on the tract in the area of the absorption trench and alternate site indicated clean sand (SM/SP/SW) material with some silt. The percolation rate of the soil was determined to be less than 1 minute per inch, More than 50% of the soil particles pass the No. 4 sieve and a sand liner is not required. No groundwater was found during the placement of the test holes and none was noted during the monitoring period. An application rate of 1.0 gallons per day per square foot was used in the design of the absorption system. We are proposing to place a new 1,000-gallon septic tank and a 45' long by 5' wide by 4' effective depth absorption trench to treat and dispose of the effluent generated in the house. The elevation of the distribution line in the absorption trench will be 3' below the surface and the total depth will be 7'. 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. The ground surface on the lot in the area of the absorption trench slopes from the northwest to the southeast at a grade of 2% to 5%. The new trench will be constructed parallel with the contours of the slope as much as possible in conformance with BLM Lot 198A, Section 18, TI5N, RIW April 26, 2012 Page Two Municipal requirements. The new septic system will be constructed a minimum of 100' from all wells and any surface water and 10' from 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. Michael E. Anderson, P.E.

Work also includes the construction of a 45' long by 5' wide by 4' effective depth absorption trench also at the location shown on the plan. The distribution line in the trench will be placed at 3.0' below the existing ground surface. Total depth of the trench will be 7.0' below the existing ground surface. The new absorption trench must be placed a minimum of 100' from all wells in the area and 100' from any surface water in the area. The septic system must also be a minimum of 10' from the water service line on the lot. A minimum of 3' of cover is required over the absorption trench and 4' of cover over the septic tank. 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. 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. The Contractor must also verify the location of wells in the area and assure that the separation distances are met, 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. o Contractors installing wastewater disposal systems must be certified by the Municipal Department of Building Safety On-Site Water and Wastewater Program for system installations. Owners installing their own systems must receive prior approval from the On-Site Water and Wastewater Program before beginning system installation. SEPTIC TANK INSTALLATION 1. A new 1,000 gallon septic tank must be procured from an approved source and installed at the location shown. 2. A septic tank is to be constructed by a certified septic tank manufacturer. Construction shall include two 4" cleanouts for pumping access. BLM Lot 198A, Section 18, T15N, R1W April 22, 2012 Page 2 of 3 3. The septic tank shall be sufficiently bedded to prevent settling or shifting of the tank. 4. All standpipes on the septic tank shall extend a minimum of 12 inches above final grade. 5. Tanks installed without 4' of cover shall have a minimum of 2" of direct budal insulation. 6. A foundation cleanout shall be installed one to four .feet from the building foundation. Two cleanouts are required between the tank and the drainfield. 7. Final grading over the tank shall be such that a positive slope exists away from the septic tank. DRAINFIELD CONSTRUCTION: 1. The drainfleld shall be constructed to the dimensions shown on the design. The bottom of the trench shall be within 2" of level. Distribution piping must be placed level with perforations down atop a level bed of drainfleld rock. Rock should then be placed over the pipe to provide a minimum of 2" of cover. 3. A silt barrier or geotextile fabric must be placed between the drainfield rock and the natural soil backfill. 4. Monitor tubes must be 4" in diameter and installed at the locations shown on the design. The portion below the distribution line must be perforated. Contractor shall vedfy the septic tank and drainfield are a minimum 100' away from any private water wells in the area, 150' from a Class "C" Well or 200' from any community well. Direct bury insulation must be placed over the distribution system if less than 3' of backfill depth is available. Finish grade over the trench must be mounded to prevent settlement or depressions. 7. Grade area surrounding the absorption trench to drain away. A minimum 2' of accepting soil is required below the drainfield rock for absorption trenches. All pockets of unacceptable materials must be removed and replaced. MATERIAL SPECIFICATIONS: BLM Lot 198A, Section 18, T15N, R1W April 22, 2012 Page 3 of 3 1. Septic tanks must be constructed by a municipally approved septic tank manufacturer. 2.

These inspections must be conducted under the supervision of a professional engineer registered in the State of Alaska. The first inspection must be conducted after the excavation of trenches, beds or pits and before the installation of any gravel. A septic tank may be set in place, but may not be backfilled. The second inspection must be conducted after the placement of the geotextile fabric, gravel, distribution piping, standpipes, cleanouts and insulation. No backfill should be in place at the time of inspection. Contractor shall provide a copy of all field survey layout and construction notes for use in preparing the certified as-built of the completed system.

The assessment of the condition of the well and septic applies only to the conditions as of the day tested.
