Box 196650 Anchorage, AK 99519-6650 Subject: New sewer/well permit— Gudveina Estates, Lot 3 Gentlemen: The owner has requested we proceed forward to obtain a septic and well permit on the subject lot. On April 11, 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 grades of approximately 2-15%. We have designed our system utilizing the existing testhole that was excavated for the proposed 5 -bedroom house. A weighted average application rate was used for the T SM layer and the 3.5' SP layer. The lot will be served by an individual well, located on the northwestern portion of the lot. We propose to install two 2' wide deep trenches. Water was not encountered during the excavation or at monitoring. 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.

EAGLE RIVER, AK 99577-8736 696-6111 / FAX (907) 696-8111 ON-SITE WASTEWATER DISPOSAL SYSTEM CONSTRUCTION PRACTICES AND MATERIAL SPECIFICATIONS LEGAL DESCRIPTION: GUDVEINA ESTATES, LOT 3 GENERAL: 1. The scope of this project includes the installation of a septic tank and/or drainfield to serve a singlrfamily 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 accuracy 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 commencing work. These discrepancies muld 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 separation distances and component layout. 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 & 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: Gudveina Est., Lot 3 Date: 04/26/06 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. 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 TRENCH/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 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. 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 backfill. 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 Pipe Perforated 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 2" thick extruded direct burial polystyrene (Dow Chemical Company Styrofoam HI or equal). 1. Septic tank inlets and outlets shall be fitted with watertight couplings (Caulder, Fernco, or equal). 1. A permeable nontoxic silt barrier (Typar 3101, Mirafi 140N, or equal) must be installed between the final leachfield gravel layer and the native soil backfill. 1. All leachfield gravel (sewer rock) shall be 0.5"-2.5" screened gravel with less than 37o passing the 71200 sieve. If deemed necessary, a sieve analysis should be performed. 1. When sand is being used as a filter material, its gradation specification must conform to current MOA or DEC requirements. Reference: Gudveina Est, Lot 3 Date: 04/26/06 Page: 3 of 3 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 MOA's and the State of Alaska's latest ordinances, regulations, or policies regarding wells and septic systems.

LEAVE THIS FORM ATTACHED TO THE PAPERWORK TABLE 3-8 FALLING HEAD PERCOLATION TEST PROCEDURE 1. Number and Location of Tests Commonly a minimum of three percolation tests are performed within the area proposed for an absorption system. They are spaced uniformly throughout the area. If soil conditions are highly variable, more tests may be reouired. 2. Preparation of Test Hole The diameter of each test hole is absorption systems or to the most surface, the sides of the hole are loose material is removed from the in. gravel are placed in the hole water is added. 3. Soaking Period 6 in., dug or bored to the proposed depths at the limiting soil horizon. To expose a natural soil scratched with a sharp pointed instrument and the bottom of the test hole. Two inches of 1/2 to 3/4 to protect the bottom from scouring action when the The hole is carefully filled with at least 12 in. of clear water. This depth of water should be maintained for at least 4 hr and preferably overnight if clay soils are present. A funnel with an attached hose or similar device ray be used to prevent water from washing down the sides of the hole. Automatic siphons or float valves way be employed to automatically maintain the water level during the soaking period. It is extremely important that the soil be allowed to soak for a sufficiently long period of time to allow the soil to swell if accurate results are to be obtained. In sandy soils with little or no clay, soaking is not necessary. If, after filling the hole twice with 12 in. of water, the water seeps completely away in less than ten minutes, the test can proceed immediately. Measurement of the Percolation Rate Except for sandy soils, percolation rate measurements are made 15 hr but no more than 30 hr after the soaking period began. Any soil that sloughed into the hole during the soaking period is removed and the water level is adjusted to 6 in. above the gravel (or 8 in. above the bottom of the hole). At no time during the test is the water level allowed to rise more than 6 in. above the gravel. Immediately after adjustment, the water level is measured from a fixed reference point to the nearest 1/16 in. at 30 min intervals. The test is continued until two successive water level drops do not vary by more than 1/16 in. At least three measurements are made. After each measurement, the water level is readjusted to the 6 in. level. The last water level drop is used to calculate the percolation rate. In sandy soils or soils in which the first 6 in. of water added after the soaking period seeps away in less than 30 min, water level measurements are made at 10 min intervals for a 1 hr period. The last water level drop is used to calculate the percolation rate. 5. Calculation of the Percolation Rate The percolation rate Is calculated for each test hole by dividinq the time interval used between measurements by the magnitude of the last water level drop. This calculation results in a percolation rate in terms of min/1n. To determine the percolation rate for the area, the rates obtained from each hole are averaged. (If tests in the area vary by more than 20 min/in., variations in soil type are Indicated. Under these circumstances, percolation rates should not be averaged.) Example: if the last measured drop in water level after 30 min is 5/8 in., the percolation rate - (30 min)/(5/8 in.) - 48 min/in. 41
