Box 196650 Anchorage, AK 99519-6650 Subject: Upgrade Sewer Permit —Muirwood Park Block 4, Lot 3 Gentlemen: The owner has requested we proceed forward to obtain a septic permit to upgrade the failed leachfield on the subject lot. The general slope of this lot is from east to west at a grade of approximately 3-8%. From the Municipality of Anchorage (MOA) records, the 5 -bedroom system was installed in July 2004. The system consists of a 1500 -gallon septic tank and an absorption trench that is 64' long x 5' wide x 4' deep (effective sewer rock). During our inspection it was discovered that the absorption field monitoring tubes had 4.5' of standing fluid. Afler review of the MOA documents, it appears that the absorption trench was installed in close proximity to the soils test (TH-10). This testhole consisted of silty sand with a percolation rate of greater than 60 minutes an inch. However, the other two testholes (TH-20 & TH-11) showed sandy soils with excellent percolating rates. The existing system was designed and permitted from MOA records TH-20 & TH-I1 soils data. Prior to construction an additional testhole in the central portion of the reserve field will be conducted to re -verify soils. With this permit submittal, we propose to install the reserve field per permit SW040089. See attached redlined design. Muirwood Park 134, L3 April 29, 2010 Page 2 of 2 The property and adjacent lots are served by public water. 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 868-3792 / FAX 868-3793..

ArcTerra Engineering & Sc .rveying, Inc. (ArcTerra) assumes no responsibility of the accuracy of the as -t uilt survey provided by the owner or owner's representative. 3. The owner or contractor is responsible to notify the engineer of any discrepancies noted on the d esign plans or drawings prior to commencing work. These discrepancies could be, . but not limited to, possible encroachments, surface water, varying soils, unplat.'.ed easements, types or use of dwellings on or adjacent to property, nearby p -iblic wells, etc. 4. The contractor shall be respi msible for locating any necessary underground utilities, easements, property lines and surface water. The owner and/or contractor shall ensure, if deet ned appropriate, that a registered land surveyor prior to construction flags all s >tbacks. The contractor shall be responsible for verifying all pertinent separatiot distances and component layout. 5. Unless specifically agreed othen rise, the property owner shall be responsible for final grading areas subsequentl3 depressed from soil settling. On all leachfield mound systems, the property owner shall be responsible for ensuring a satisfactory vegetation growth ow -r the mounded area. 6. The MOA Development Service : Department On -Site Water & Wastewater Program must certify contracto •s installing wastewater disposal systems. Owners installing their own systet .is must also receive prior approval from said MOA Department. SEPTIC TANK/ HOLDING TANK/ LIFT STATION INSTALLATION: 1. A septic tank is to be constructec 1 by a certified septic tank manufacturer. Construction shall include two 4" ele anouts for pumping access. 2. The septic tank shall be sufficie. ntly bedded with proper material and compacting to prevent damaging, sett ling or shifting of the tank. 3. All standpipes on the septic tank shall I extend a minimum of 12 inches above the final grade. Muirwood Park B4, L3 April 29, 2010 Page 2 of 4 4. 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. 5. 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. 6. Final grading over the septic tank shall be such that a positive slope exists away from the septic tank. 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. 8. 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. 2. Once the sewer rock is installed, the distribution pipe is installed level with the perforations facing downward. Gravel is then to be placed over the distribution pipe to provide a minimum of 2 inches of cover over the pipe. 3. 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 backfill. 4. 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. 5. 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. 6. 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. 20441 PTARMIGAN BLVD • EAGLE RIVER, AK 99577-8736 • PH (907) 868-3791 • FAX (907) 868-3793 Muirwood Park B4, L3 April 29, 2010 Page 3 of 4 MINIMUM MATERIAL SPECIFICATIONS: 1. A MOA approved septic tank manufacturer must construct any septic tank proposed for installation. 2. The following pipe materials are MOA approved for use in septic system installations: Type of Pip Cast Iron ASTM D3034 (PVC) ASTM F810 (HDPE) ASTM D2662 (ABS) 3. Insulation shall be at least Perforated Solid Yes Yes Yes Yes Yes No Yes Yes 2" thick extruded direct burial polystyrene (Dow Chemical Company Styrofoam HI or equal). 4. Septic tank inlets and outlets shall be fitted with watertight couplings (Caulder, Fernco, or equal). 5. A permeable nontoxic silt barrier (Typar 3401, Mirafi 140N, or equal) must be installed between the final leachfield gravel layer and the native soil backfill. 6. All leachfield gravel (sewer rock) shall be 0.5"-2.5" screened gravel with less than 3% passing the #200 sieve. If deemed necessary, a sieve analysis should be performed. 7. When sand is being used as a filter material, its gradation specification must conform to current MOA or ADEC requirements. INSPECTIONS: Typically there will be three (3) inspections required during the installation of the wastewater disposal system. These inspections will occur as follows: 1. The first inspection must be conducted after the excavation of ditches, pits, trenches, or beds and before the installation of any gravel. A septic tank may be set in place, but may not be backfilled before this inspection. 2. The second inspection must be conducted after the placement of the sewer rock, distribution lines, standpipes, and cleanouts, but before the placement of the silt barrier, insulation, or any other backfill. 3. The final inspection is to occur upon final grading of the property. Often there will be more than these 3 inspections required, especially with the installation of multiple trenches, sand filters, pressurized distribution systems, etc. The inspecting engineer is to be contacted at least 24 hours prior to the start of construction. If necessary, a pre -construction meeting will take place on-site. The inspecting engineer will not coordinate, direct or control in any way the contractor's activities. The owner shall contract with the contractor to perform the work outlined in these specifications and attached plans and in accordance with the attached MOA permit. All materials, components, and construction practices shall comply with the MCA's and the State of Alaska's latest ordinances, regulations, or policies regarding wells and septic systems.

We are therefore requesting a permit be issued for the construction of a new septic system to serve the new home. The subdivision is served by the Municipal water system and no conflicts exist with adjacent septic systems or wells. The attached Site Plan and backup documentation identify the location and configuration of the proposed septic system and alternate site. Existing spot elevations and the current drainage pattern are identified on the Site Plan. The drainage pattern will be maintained after development of this lot is complete. Test holes placed on the lot during the subdivision phase indicated silty sand with some gravel in the area of the absorption trenches. The accepting soils were tested and found to have percolation rates of less than 1 minute per inch. No groundwater was found during excavation and none was noted during the monitoring period. Our design includes the placement of a new 1,500 -gallon septic tank along with a 63' long by 5' wide by 4' effective depth absorption trenches to collect and treat the sewage generated in the house. The bottom of the trench will be 6' below the surface. The distribution pipe will be 2' below the surface. A minimum of 3' of cover will be placed atop the trenches and a minimum of 4' of cover will be placed atop the new septic tank. The ground surface on the lot slopes at shallow grades from west to east as shown on the Site Plan. The absorption trench will be constructed parallel with the slope of the ground surface as much as possible in conformance with Municipal requirements. The new septic system will be constructed a minimum of 10' from the water service proposed for the lot and on adjacent lots. It will also be constructed a minimum of 100' Lot 3, Block 4, Muirwood Park April 23, 2004 Page Two from any surface water in the area If the system is constructed in accordance with our design the following statements apply: 1. 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. 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, 14.jE a"-", Michael E. Anderson, P.E.

Name of Firm Gayness Engineering Group, LTD. (GEG) Phone 907-337-6179 Engineer's Printed Name Jeffrey A. Gamess Date In conducting this evaluation, GEG provided an engineering evaluation of the well and/or septic system in accordance with the guidelines and regulations established by the Municipality of Anchorage and industry practices. The reported results describe the condition of the system/s on the date/s of the evaluation. Separation distances were measured to readily identifiable features. Hidden defects or encroachments may exist that were not identified during the evaluation. The operational life of all wells and septic systems depend upon a variety of variables, including (but not limited to) soil conditions, groundwater levels (that may fluctuate during the year), quality of construction (materials and workmanship), and the water usage of the family utilizing the system/s. These conditions can vary, and are outside the control of GEG. Satisfactory test results do not guarantee future performance of the systems; therefore, GEG makes no warranty (express or implied) regarding the future performance of the well or septic system. GEG makes no representation whether an alternative well or septic system can be installed on the property in the event either of the current systems fail to perform adequately in the future. The content of this report is for the sole benefit of the person/party that retained GEG to perform the evaluation.
