Box 196650 Anchorage, AK 99519-6650 Subject: New sewer/well permit —T15N R1W SEC 9 LOT 107 Gentlemen: The owner has requested we proceed forward to obtain aseptic permit on the subject lot. On November 9, 2006 one testhole was performed for the proposed system. The results of this test are attached. The general slope of this lot is from east to west at a grade of approximately 3-5%. The existing undocumented system has been disconnected from the residence and abandoned in place per code. Three low producing, nonconforming wells are to be decommissioned and a new well drilled in the northeast portion of the lot. We have designed our system utilizing the existing testhole that was excavated for the existing 3 -bedroom house. The lot will be served by an individual well, located on the northern portion of the lot. We propose to install two 5' wide shallow trenches. Water was encountered during the excavation at 6, and during monitoring at 5'. There are no public or private wells within 200' of our proposed system location except as noted. There is no surface water within 100' of the proposed system and there are no known curtain drains within 50'. We do not expect there to be any adverse effect on adjacent lots by the development of this system. If you have any questions, please contact me at 696-6111/FAX 696-8111.

The scope of this project includes the installation of aseptic tank and/or drainfield to serve a single family residence on the referenced property as delineated on the attached Municipality of Anchorage (MOA) permit and site plan. 1. Construction shall be in accordance with the approved site plan and design drawings; MOA permit with any special provisions or conditions, and all applicable State and Municipal Wastewater Disposal Regulations. 1. KND Engineering Inc (KND) assumes no responsibility of the accuraty of the as -built survey provided by the owner or owner's representative. 1. The owner or contractor is responsible to notify the engineer of any discrepancies noted on the design plans or drawings prior to commenting or These discrepancies could be, but not limited to, possible encroachments, surface water, varying soils, unplatted easements, types or use of dwellings on or adjacent to property, nearby public wells, etc. 1. The contractor shall be responsible for locating any necessary underground utilities, easements, property lines and surface water. The owner and/or contractor shall ensure, if deemed appropriate, that a registered land surveyor prior to construction flags all setbacks. 1. The contractor shall be responsible for verifying all pertinent component layout. separation distances and 1. Unless specifically agreed otherwise, the property owner shall be responsible for final grading areas subsequently depressed from soil settling. On all leachfield mound systems, the property owner shall be responsible for ensuring a satisfactory vegetation growth over the mounded area. 1. The MOA Development Services Department On -Site Water 6r Wastewater Program must certify contractors installing wastewater disposal systems. Owners installing their own systems must also receive prior approval from said MOA Department. SEPTIC TANK / HOLDING TANK / LIFT STATION INSTALLATION: 1. A septic tank is to be constructed by a certified septic tank manufacturer. Construction shall include two 4" cleanouts for pumping access. 1. The septic tank shall be sufficiently bedded with proper material and compacting to prevent damaging, settling or shifting of the tank 1. All standpipes on the septic tank shall extend a minimum of 12 inches above the final grade. 1. Septic tanks installed with less than 4 foot of cover shall be insulated. The contractor will ensure that the fill over the tank does not exceed the burial depth rating. 1. A foundation cleanout shall be installed one to four feet from the building foundation. In the line between the tank and the leachfield there shall be two adjacent cleanouts (unless an effluent pumping system exists within the septic tank). These cleanouts shall be located on undisturbed soil not more than 10 feet from the tank. The second cleanout, in line, shall be to clean toward the septic tank. 1. Final grading over the septic tank shall be such that a positive slope exists away from the septic tank. Page 1 of 3 Reference: T15N R1W SEC 9 LOT 107 Date: 11/22/06 Page: 2 of 3 7. All H.D.P.E. tanks shall have a vertical length of 4 -inch perforated drainpipe besides the tank extending to the bottom of the tank to above grade to monitor ground water. S. All tanks shall be anchored when there is not enough adequate soil cover to resist buoyancy forces in high -groundwater areas. 9. All holding tanks and lift stations shall have an audible and visual alarm inside the residence. 10. All lift stations shall be wired in compliance with the Uniform Electrical Code and all MOA guidelines. 11. The contractor shall remove the old tank, or abandon it in compliance with the Uniform Plumbing Code. The contractor is solely responsible for the abandonment procedure. ABSORPTION TRENCII/DRAINFIELD INSTALLATION: 1. Excavate the proposed trench to the dimensions shown on the design. The bottom of the excavation shall be within 2 inches of level. If the sidewalls of the excavaction become smeared, they must be raked or scratched (roughed -up) before gravel (sewer rock) placement. 1. Once the sewer rock is installed, the distribution' installed level with the perforations facing downward. Gravel is then to be placed over the distribution tribution pipe to provide a minimum of 2 inches of cover over the pipe. 1. A silt barrier must be installed between the final gravel layer and the native soil backfill. Ensure the silt barrier covers the entire gravel surface before placing ball. 1. Monitoring tubes shall be four- (4) inch diameter, installed approximately in the locations shown on the design, and extend a minimum of 12 inches above final grade. The portion of the monitoring tube extending through the gravel shall be perforated from the bottom of the trench to the invert of the distribution pipe. This is equivalent to the effective depth of the gravel as noted on the design. 1. Backfill over the final gravel layer must not be less than twenty-four inches. Insulation must be installed when the backfill depth is less than thirty-six (36) inches. The finish grade over the trench must be mounded to prevent the formation of a depression after settling. 1. All advanced technology waste water disposal systems (Advantex, Biocycle, Intermittent Dosing Sand Filter, etc...) shall be constructed, installed, maintained and monitored per manufacturer's specifications and MOA requirements. MINIMUM MATERIAL SPECIFICATIONS: 1. A MOA approved septic tank manufacturer must construct any septic tank proposed for installation. 1. The following pipe materials are MOA approved for use in septic system installations: Type of PipesPerforate olid Cast Iron Yes Yes ASTM D3034 (PVC) Yes Yes ASTM F810 (HDPE) Yes No ASTM D2662 (ABS) Yes Yes 1. Insulation shall be at least Y' thick extruded direct burial polystyrene (Dow Chemical Company Styrofoam HI or equal). 1.
