If this was a well permit and the well has been drilled, a well log must be sent to this office for documentation of the installation and to close the permit. If this permit was for a wastewater disposal system, an original as -built inspection report must be sent to this office for review, approval and documentation. This as -built inspection report must be signed by the licensed Professional Engineer who inspected the installation of the system. As -built inspection reports are required to be submitted within 30 days of the completion of the system. If no system was installed under this permit, and you are still planning to install a well or wastewater disposal system, a new permit must be obtained from this office. A new permit for a second year may be issued for a fee of $115.00 if the renewal application is received on or before the expiration date of the original permit. When applying for a new permit, the fees are: $460.00 for a wastewater permit and $175.00 for a well permit. If you have any questions, please call this office at 343-7904.

Box 19-6650 Anchorage, AK 99519 Dear Sirs: The purpose of this letter is to provide the required design narrative in support of our application for a permit to construct wastewater disposal facilities on Lot 2 Block 1, Aspen Ridge S/d, located on Prator Street in Anchorage. Soils logs, pert test results, a site plan, design drawings and specifications are enclosed for your review. The proposed system will be constructed in the vicinity of test hole 9 1. As can be seen from the soil log, the native material between 1 and 2.5 feet below ground level is a sandy loam with a measured perc rate of 2 minutes per inch, which corresponds to a soil application rate of 1.2 gpd/sq. ft. This is underlain by a sandy silt with a measured perc rate of 54 minutes per inch, which corresponds to a soil application rate of 0.45 gpd/sq. ft. Although the proposed trench has 6 feet of gravel beneath the horizontal distribution pipe, we are basing the design on the upper 4 feet of this being the effective gravel depth. Thus, each lineal foot of trench can accept (2 x 1.5 x 1.2) + (2 x 2.5 x 0.45) = 5.85 gallons per day. Thus, this proposed 4 -bedroom residence requires a total trench length of 600/5.85 = 103 feet. The proposed design has a total of 104 feet of trench. The topography of the lot in the area of proposed construction is generally level. The size of the replacement trench shown on the site plan is based on it being preceded by a Category II advanced treatment tank. The proposed project will have no significant impact on present or future water supply and wastewater disposal systems serving adjacent properties, nor will it have any significant impact on reserved space -surface and subsurface, or on drainage. Please give me a call at 345-1355 if you have any questions on this submittal. Sincerely, Ted Moore, P.E.

Minor deviations from these drawings may be allowed or required by the engineer conducting the inspections. All construction procedures and material specifications shall conform to Municipal and State requirements. All separation distances shall be in conformance with Municipal requirements, unless specifically waived. 1.3 The contractor shall be responsible to obtain any necessary utility locates, and to work around any buried utilities. 1.4 The contractor shall provide adequate cover material and rough grading over all system components to ensure that proper drainage is achieved after settlement and that there are no residual depressions. Insofar as possible the contractor shall minimize damage to trees and existing lawn areas. 1.5 Unless specifically agreed otherwise, the homeowner shall be responsible for finish grading after the soil is compacted, as well as placement of topsoil and reseeding all areas disturbed by the construction. 2.0 Septic Tank: 2.1 The new 1250 -gallon, 2 compartment septic tank shall be Municipally approved and shall be set level on undisturbed soil. Each compartment shall be equipped with a watertight manhole cover and a 4" cleanout. If the tank is buried less than 4 feet, it shall be insulated with 2 inches of approved burial type, rigid insulation. 2.2 All pipe connections to the tank shall be equipped with waterproof mechanical couplings. The waste line from the residence to the septic tank shall have a minimum slope of 1/4"' per foot, and the waste line between the tank and the soil absorption system shall have a minimum slope of 1/8" per foot. A cleanout shall be installed 1 - 4 feet from the building foundation, and a double cleanout shall be installed within 5 feet downstream of the septic tank. I 3.0 Soil absorption system: 3.1 The soil absorption system shall be constructed by excavating two parallel 52 -foot long trenches spaced 15 feet apart to a depth of 7 feet below ground level. The long axis of the excavation shall parallel an existing contour 3.2 The bottom of the excavations shall be level. Any compacted or smeared surfaces shall be raked to allow proper infiltration. Sand for leveling or serving as filter material shall comply with Municipal specifications. 3.3 A total of 6.5 feet of approved sewer gravel shall be placed in the bottom of the excavations with the perforated distribution pipes laid level such that the pipe inverts are no less than 6.0 feet above the bottom of the sewer gravel. Sewer gravel shall be 0.5" - 2.5" screened gravel, with less than 3% passing the #200 sieve. 3.4 Monitor tubes and cleanout pipes shall be of 4" diameter and installed in the locations shown on the design drawings. The portion of the monitor tube extending through the sewer gravel shall be perforated. 3.5 Approved filter fabric shall be placed over the entire top surface of the sewer gravel. A minimum of 2 feet of soil cover is to be placed over the filter fabric. If the soil cover thickness is less than 3 feet, two inches of rigid, burial type insulation is to be placed over the entire top surface of the gravel, in addition to the filter fabric. 3.6 The top surface of the cover material shall be raised a minimum of 18 inches higher than the surrounding terrain to allow for subsequent settlement, and shall be graded to smooth contours. Fill slopes shall be no steeper than 3:1. 3.7 Unless specifically agreed otherwise the homeowner shall be responsible for arranging to have the site finish graded after the backfill material has stabilized, and for placement of adequate topsoil and seed to promote rapid revegetation of all areas disturbed by the construction. 4.0 Inspections: 4.1 A minimum of 4 engineering inspections will be required during the course of the project: (1) initial stakeout with the contractor to establish the location of the system and to discuss the plans, specifications and construction procedures, (2) after the native material has been excavated to expose the infiltrative surface to ensure that it is level and at the right elevation, and conforms with the soil test information, (3) after the sewer gravel is in place and the distribution pipes have been laid and connected up to the septic tank, but prior to placement of insulation or filter fabric, and (4) after rough backfill and grading is complete. The septic tank requires one inspection after it is set level and the piping connected, but prior to backfill. This inspection may be incorporated with any of the above inspections. 4.2 The installer shall coordinate the timing of the inspections with the engineer sufficiently far in advance to ensure the availability of the engineer.

DUFFUS Date 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 occupants or can ArcTerra guarantee that no unseen OF encroachments, deficiencies or discrepancies exist. /���1 �-: f s 10'r �,r 6.
