The duplex is currently served by an older 6 bedroom septic system, which reportedly consists of a septic tank and a steel seepage tank. The seepage tank has collapsed and needs replaced. The owner wishes to install an advantex system suitable for 6 bedrooms due to the limited area suitable for a septic system. We are requesting the approval of two waivers required for the installation of the septic system: 1. We are requesting the 100' separation distance required for the tank to surface water be waived to 90'. Relocation of the septic tank beyond 100' from the creek, would necessitate that it be installed in the driveway. It is not believed that the installation of the tank within 90' of the creek will cause adverse impact. The heavy walled tank in this location will be a significant improvement over the old tank and seepage tank within 100' of the creek. 2. We are requesting a cross slope waiver for the leach field, which must be installed parallel to the prevailing grade of 7%, perpendicular to the contours. We do not believe this will cause any significant impacts, as excavation depth vs slope has been considered. A sketch is included with this application. The soils are poorly graded sand with some gravel. A percolation test was attempted, and the soils were observed to absorb the water extremely fast, indicating a percolation rate less than 1 minute per inch. The photograph included with this submittal shows the soils are very sandy. As such, we are requesting that the permit be issued without the requirement for a sand liner. Ground water was not encountered. Installation of the proposed system will not significantly impact adjacent lots. Drainage is not a major consideration in this design. Included with this letter are plans, specifications, soils logs, calculations, and other supporting documentation. Thank you for your time in reviewing this permit request. Please do not hesitate to contact me at 907-854- 5558 or by email cqbalzarini~,qmail.com with any questions, concerns, or if you need additional information. Sincerely, C&M ENGINEERING SERVICES Ph: 907-854-5558 SPECIFICATIONS FOR ONSITE SEPTIC SYSTEM - MOA CERTIFIED INSTALLER LEGAL: T15N R1W SEC31 SW4 SW4 NW4 SW4 April1 2016 A. GENERAL 1.

All excavations and depths are advisory and are to be verified in the field by the contractor to meet Municipality of Anchorage, Department of Environment of Conservation requirements. It is the responsibility of the owner to obtain all necessary permits or easements and to locate any adjacent multi-family wells. A licensed surveyor should locate all nearby lot lines, easements, exact 100' radius from the existing and neighboring on- site wells, and any nearby surface water. 7. The excavation is to be exactly in the area shown on the site plan, any deviation requires engineer approval. 8. Any remaining open test hole excavations shall be filled and monitor tube removed, after construction of the Drainfield. 9. The contractor shall provide the engineer with adequate notice to perform inspections. 10. Insulate the sewer line if it passes under the driveway or parking area, with a minimum of 2" extruded board insulation, rated for burial, and on the moa approved list. B. SEPTIC TANK. Septic tank shall be a steel, 3000-gallon tank capacity of MOA approved construction. Installed to meet MOA requirements, and shall be plumbed for two 20 filter pods Install a foundation cleanout within 5' of the foundation. A combination of soil and 2" minimum of insulation shall be placed over the tank, to prevent ponding and promote drainage. The insulation shall be rated for burial and meet moa requirements. DRAINFIELD The Drainfield is to be located as shown on the site plan. Notify Engineer of any changed site conditions. The total depth of the initial drainfield excavation is to be at maximum 7' deep Bottom of excavation shall be level +/- 1.5" max. if bedrock or inconsistent soils are encountered, notify the engineer immediately. In the event of over-excavation, a moa filter sand shall be used to maintain the 6' separation distance from the bottom of each trench to the bottom of the test hole(s).The top of the sand layer shall be level, plus or minus 1.5", and raked, prior to placing sewer rock. Care shall be taken to not compact the sand. A 2 foot effective layer of sewer rock is to be placed in the each trench. The effluent piping is to be set on top of this layer, buried with sewer rock, with 2" of sewer rock cover over the piping. The Distribution pipe shall be 4" sch. 40 pvc pipe conforming to ASTM D3034. The complete Drainfield gravel and piping is to be covered with a geotextile filter fabric. Soil or combination of soil and extruded board insulation to a depth of 4' or equivalent is to be placed over the drainfield. Mounded side slopes shall not to exceed 3:1. The minimum insulation thickness shall be 2". Insulation shall be moa approved and rated for burial. The septic tank and leachfield must not be closer than 100' to any existing private well, 150' to any Class "C" well, or 200' to any community well.
