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 upgrade the wastewater disposal facilities on Lot lA, Lookout S/D, located at 11600 Cobra Avenue. The existing steel septic tank is now 28 years old and in danger of imminent collapse. The plan is to replace the septic tank with a "Biocycle" aerobic treatment unit that will discharge effluent into the existing concrete ting seepage pit, and hopefully thereby enhance and extend its performance. A site plan as well as a design plan and cross-section are enclosed for your review. The topography of the lot in the area of proposed construction slopes down towards the west at approximately 10%. The proposed p/'oject 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. The property owners, Will and Carlene Knoppe, have been informed of the need to come in to your office and execute the required maintenance agreement prior to receipt ofthe permit. 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 buffed 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 oftopsoil and reseeding all areas disturbed by the construction. 2.0 Existing wastewater disposal system: 2.1 The existing septic tank must be properly abandoned by thoroughly pumping, removing the top and backfilling with soil. 3.0 "Biocycle' Aerobic Treatment Unit 3.1 The new 1500 gallon "Biocycle" aerobic treatment unit shall be manufactured, furnished and equipped by Pegasus Engineering in accordance with the Municipal and State approved design. 3.2 The contractor shall be prepare a suitable site for the "Bioeycle" unit and install it as follows: The location of the unit shall be chosen to maintain a separation distance in excess of 100 feet from all neighboring private wells. The depth of the excavation for the "Biocycle" treatment unit shall be sufficient to allow connection to the 4" waste line leaving the house at a minimum slope of W' per foot, but no deeper than 8'-9" below finish grade in the vicinity ofthe unit. A cleanout shall be installed within 5 feet of the building foundation. All pipe connections to the "Biocycle" shall be equipped with waterproof mechanical couplings. The bottom ofthe excavation for the "Bioeycle" treatment unit shall be carefully leveled and smoothed by the placement of a layer ofclean sand. Two inches of rigid, burial type, insulation with a minimum compressive strength of 30 psi shall be placed on the sand prior to installation ofthe "Biocycle" treatment unit. The space between the sidewalls of the excavation and the "Biocycle" unit shall be carefully backfiIIed with sand. The top of the manhole riser shall extend 4" above finish grade, and the final ground surface graded as necessary to provide surface drainage away from the "Biocycle unit. -3.3 The contractor shall be responsible to obtain any necessary electrical permit and inspections. 3.4 The control and alarm floats shall be set and their proper operation verified by the "Bioeycle" supplier. The high level alarm shall be installed inside the residence at a location selected by the owner. 3.5 The discharge line from the "Biocycle' treatment unit to the existing concrete ring seepage pit shall be 1.25" dia. Sched 40 PVC. All pipe connections in the distribution system shall be glued, and the ends of all pipes capped. 4.0 Inspections: 4.1 A total of 3 engineering inspections will be required during the course of the project: (I) initial stakeout with the contractor to establish the location of the system and to discuss the plans, specifications and construction procedures, (2) after the "Biocycle" tank has been set in place and pipes connected, but prior to backfill and (3) after rough backfill and grading is complete. 4.2 The installer shall coordinate the timing ofthe inspections with the engineer sufficiently far in advance to ensure the availability of the engineer.
