We request an expedited permit due to the health and safety of the collapsed tank. The proposed upgrade will serve the existing 4- bedroom house. The lot and area is served by a private wells and there are no wells within 100’ of the proposed septic tank. The proposed design will not impact any of the neighboring properties due to the lot layout. Please contact Brent M. Western or me if you have any questions. Sincerely, Michael N. Anderson, P.E.

ANCHORAGE, ALASKA 99503 PHONE: 907.279-2581 September 15, 1975 WO #17518 Mr. Jerry Good Star Route A, Box 1584 Anchorage, AK 99507 Subject: Subsurface Investigation for On-Site Sewer Lot 8, Block B, Knik Heights Subdivision Dear Mr. Good: As requested, we performed a subsurface investigation to determine the suitability of the subsurface soils on the above referenced lot, for placement of an on-site sewage disposal system. The exploration was conducted on September 10, 1975 utilizing a Mobile Drill B-50 drill rig, mounted on a Flextrac-Nodwell tracked vehicle owned and operated by Denali Drilling, Inc. The drilling was supervised and the test hole logged by Mr. Pete Herstek, staff technician with Alaska Testlab. One test hole was placed 0n the lot to a depth of 20' as located on Figure 1. The log of the test hole is enclosed as Table A. It will be useful, to properly interpret the test hole log, to read the standard explanatory information contained in the back of this report. After the hole was drilled it was filled with water and allowed to stand overnight. The next day, Thursday, September 11, 1975, Mr. Herstek returned to the lot and refilled the hole with water to within 37" of the surface. Over the next hour the water level was carefully monitored and after 60 minutes the water level had dropped to 67.25" below the ground surface, for a percolation rate of 2.0 minutes/inch. Utilizing the data tabulated in Table A-- "Absorption Area Requirements for Individual Residences", on page 8, of 'the "Manual of Septic Tank Practice" published by the U.S. Department of H~atth, Education & Welfare, the absorption area requirements, per bedroo~ for a sewer system placed in this soil is 85 square feet per bedroom. Please note that on the date of exploration, no water table was encountered. It should be remembered, though, that the water table will normally fluctuate with seasonal and climatic changes. Mr. Jerry Good September 15, 1975 Page 2 We hope this is sufficient to your present needs. If we can be of further service please do not hesitate to contact us. Thank you.

Bottom of Test Hole: Frost Line: Free Water Level: 20.0' None observed None Observed Test Hole Log - Description Guide The soil descriptions shown on the logs are the best estimate of the soil's characteristics at the time of field examination and as such do not achieve the precision of a laboratory testing procedure. Iftbe log includes soils sanlples, those samples receive an independent textural classification in the laboratory to verify the field examination. The logs often include the following items: Depth Interval - usually shown to 0.1 foot, within that zone no significant change in soil type was observed tbrougb drill action, direct observation or sampling. Frost Classification - NFS, Fl, F2, F3, F4, see "Soil Classification Chart" Texture of Soil - An engineering classification of the soils by particle size and proportion, see "Soil Classification Chart", note the proportions are approximate and modifications to tile soil group due to stratification, inchlsions and changes in properties are included. Moisture Content - ibis is a qualitative measure: dr_zy_, no or little apparent surface moisture, damp, moisture forms portion of color, less than plastic limit, ,.vet, no free water, often soft, if cobesive soil~ saturated, free water may be squeezed out, ifa free drainiug soil; dilatent at natural moisture content, if a non-plastic silt or fine sand. (Tbe moisture content is further defined by reference to PI, LW, NP. M%or dilaten,_y.} Densit[ - refers to more-or-less non-cobesive soils, such as sand gravel mixtures with or witbout a fine fraction, derived from drilling action and/or sample data; usually described as: very loose, loose, medium dense, very dense. Genera] intent is to portray earthwork characteristics. Stiffness -- refers to more-ordess cohesive soils and fine grained silts of the clay-silt groups. Derived from drill action and/or sample data. Very soft. soft, stiff, very stiff and bard are commonly used terms. Particle size - Tbe largest particle recovered by the split spoon is 1-3/8", Shelby tube 3", auger flights (minute-man) 2", Auger flights (B-50 hollow stem) 6"-8". Larger particles are described indirectly by actiou of the drilling and are referred to as cobbles, 3" to 8", or boulders 8"+. Therefore when revic',ving tile gradation sheets, if any. the description on tile hole log must be considered for an indication of larger particles. Unified Soil Classifi~:ation - Tbis is a two letter code. See Unified Classi.fication sheet for further definition. In some cases AASHO and/or [:AA soil classifications may be sbown ils ,.veil as the unified. Atterberg Limits useful for fine grained and other plastic soils.

Quantity described as; trace, or an estimate of volume, or, in case of all organic, - as Peat. This may include tundra, muskeg and bog material. Muck -- a modifier used to describe very soft, semi-organic deposits usually occuring below a peat deposit. Amorpbus pea[ organic particles nearly or fully disintegrated. Fibrous Peat - organic particles more-or-less intact. Bottom of Testbole -- includes last sample interval.
