The general slope of this lot is approximately flat (0-2%) over the septic area. On June 30, 2011 two testholes were performed to investigate soils and groundwater.

The proposed building elevation also makes it necessary to install a STEP tank six feet below the original grade and pressurize the drain field. Both components have been redesigned to accommodate the additional bedroom that is being added to the proposed structure. The drainfield and septic tank remain in the vicinity of the originally permitted design and an additional test hole will be dug to insure consistant soil conditions prior to construction, and as such, do not pose any significant change to the current permit. 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'.

On all leachfield mound systems, the property owner shall be responsible for ensuring a satisfactory vegetation growth over the mounded area. 6. 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. 2. The septic tank shall be sufficiently bedded with proper material and compacting to prevent damaging, settling or shifting of the tank. 3. All standpipes on the septic tank shall extend a minimum of 12 inches above the final grade. Sampson Estates Blk 2 Lot 4 August 5, 2011 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 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. 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 Sampson Estates Blk 2 Lot 4 August 5, 2011 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 Pipe Perforated Solid Cast Iron Yes Yes ASTM D3034 (PVC) Yes Yes ASTM F810 (HDPE) Yes No ASTM D2662 (ABS) Yes Yes 3. Insulation shall be at least 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 MOA's and the State of Alaska's latest ordinances, regulations, or policies regarding wells and septic systems. The failure of the inspecting engineer to notice a material or construction non- compliance does not relieve the contractor of his/her responsibility to correct such deficiency. There will be no contractual arrangement existing between the contractor 20441 PTARMIGAN BLVD • EAGLE RIVER, AK 99577-8736 • PH (907) 868-3791 • FAX (907) 868-3793 Sampson Estates BIk 2 Lot 4 August 5, 2011 Page 4 of 4 and ArcTerra.

DUFFUS Date 4/15/13 Engineer's Comments: This investigation was completed in compliance with ADEC and MOA regulations. The assessment of the condition of the well and septic applies only to the conditions as of the day tested. The flow and absorption rates may change due to subsurface conditions that may not be observed from the surface, changes inland use, local soil characteristics, groundwater levels that may fluctuate during the year and the water usage of the family being served by the system. The operational life of all well and septic systems are subject to these various and dynamic characteristics and are outside the control of the evaluator of the well and septic system. Therefore, ArcTerra can not give any estimate of how long a system will function satisfactory for current or future*Aoccupants or can ArcTerra guarantee that no unseen �"' Cly' 4� encroachments, deficiencies or discrepancies exist.
