The existing trench is to be abandoned in place. Construction shall be in accordance with the approved site plan and design drawings, Municipa~ permit with any special provisions or cond~ons, and all applicable State and Municipal Wast~ater Disposal Regulations. 3. The co~Lactor shall be responsible for obtaining any necessary underground uti~y locates. U~ess spe~fica~y agreed otherw~e, the property owner sha~ be responsible for final grading areas subsequently depressed from soil s~ng. On ail leachfi~Id mound systems, the property owner shall be responsible for ensuring a sat~factory vegetation growth over the mounded area. Contractors installing wastewater d~posal systems must be certified by the Municipal Health Depar£ment for system installations, Owners installing their own systems must also receive prior approval from the Municipal Health Depar~ent. SEPTIC TANK INSTALLATION: A septic tank is to be constructed by a certified septic tank manu~act~¢r. Construction sha~ include two 4" cleanout~ for pumprng access. 2. The septic tank shall be sufficiently bedded to prevent s~tt~ing or shifting of the tank. 3. All standpipes on the septic tank shall extend a mi~n~m of 12 ineh~s above fina~ grade. 4. Septic tanks installed with less than 4' of cover shall be insulated. 17034 NORTH EAGLE RIVER LOOP" SUITE 204 * EAGLE RIVER, ALASKA 99577 Page Two Lot 14; Tan~ina Hills Subdivision Dec~mb~L 14, 1994 A foundation ~l~anout shall be installed one to four fe~t from the building foundation. In the line b~tween the tank and the leachfield there sh~ be two adjacent ~eanouts (unless an effluent pumping system exist~ within the septic tank). These ~eanouts shall be located on undisturbed so~l not more than 10' from thc tank. The first ~leanout, in line, sha~ be to ~lean toward the leachfield. The second clcanout shall be to clean to,rd the septic tank. Final grading over the septic tank shall be such that a positive slope exists away from the septic tank. ABSORPTION TRENCH/I)P. AINFIEL~) INSTALLATION: Excavate the proposed trenches to the dimensions shown on the design. The bottom of the excavation shal~ be within 2 inches of level. If the sidewal~ of the excavation become smeared, they must be raked or scratched (roughed-up) before gravel (s~w~r rock) placement. Once the ~ravel is installed, the distribution pipe is to be installed level with the p~rforations faced downward. Grav~ is then to be placed over the distribution pipe to provide a minimum of 2 inches of cover over the pipe. A silt barrio[ must be installed between the final gravel layer and the native so~l backfill. Ensure the silt bar;~r covers the entire gravel surface before pla~ng backfill. Monitor tubes shall be of fo~ (4) inch diameter and installed approximately in the loca~ons shown on the design. The portion of the monitorin~ tube extending through the grav~, shall be perforated from the bottom of the trench to the invert of the dist~bution pipe. Thi~ is equivalent to the effective depth of the ~ravel as noted on the design. Backfill over the final grav~ layer must not be less than twenty-four (24) inches. Insulation must be installed when the backfill depth is less than thirty-six (36) inches. The fish grade over the trench must be mounded to prevent the formation of a depression aft~[ settling. UINI~U~ I~ATE~IAL SPECIFICATIONS: I. Any septic tank proposed for installation must be constructed by a Mu~i~pally approved septic tank manufacturer.

Insu2ation sh~ be at least 2" thick exCLuded direct burial polystyrene (Dow Chemical Company Styrofoam HI or equal). 4. Septic tank i~ts and outlets shall be fitted with watertight couplings (Caulder, Fernco, or equal). A permeable nontoxic s~ barrier (Typar 3401, Mirafi 140/~, or equal) mast be inst~ed b~tween the final leachfi~d gravel layer and the native so~ backfill. 6. All l~achfield grav~ (s~wer rock) sha~ be 0.5"-2.5" screened gravel with less than 3% passing the #200 sieve. 7. When sand is b~ing used as a filter material, its gradation specifications must conform to current M.0.Ao or D.E.~. requirements. INSPECTIONS: Typically there wi~ be a minimum of three (3) inspections required du~ng the instat2ation of the wastewat~L disposal system. These inspectio~ will occur follows: I. The first inspection mast be conducted after the excavo~tion of d~¢hes, pit~, ~enches, or bed~ and before the i~stallation of any gravel. A septic tank may be s~t in place, but may not be backfd2~ed before this inspection. 2. The second inspection must be conducted after the placement of the s~lt barrier, gravel, distribution lines, standpipes, cleanoat~, and ins~ation, but before the placement of any other backf~.

Attention: Hugh Gellert Subject: Soils Investigation and Percolation Test Results Tanaina Hills Subdivision Gentlemen: We have completed a series of test bo~ings and percolation tests in the Tanaina Hills Subdivision. Seven borings were drilled in the right-of-way of Kitksa Drive and Kiliak Place and four borings, with perco'lation tests, were drilled on. Lots 12 through 15 as shown on Figure 1. The purpose of the borings in the street was to obtain soils information for use in design of the street improvements. The percolation tests were performed to verify that on-site septic systems could be constructed on these lots. The borings were drilled with a Mobile B-50 drill mounted on a Nodwell carrier and equipped with continuous flight augers. The drill rig is owned and operated by De~all Drilling, !nc. ~h test borings were logged by Oz Hatch,~a~s_k_~a_~s~_~-~I engineering geologist. Soil samples were obtained as the auger brought the soil to the surface. These samples were placed in plastic bags to preserve the natural moisture content. In the laboratory, the samples were again visually classified and the dry strength and the moisture content of each sample was measured. For reference, samples of similar color, grain size distribution and texture were placed in arbitrary groups. A hydrometer grain size analysis was conducted on the predominate soils group. Soils in the subdivision are predominately fine silty sands and sandy coarse silts. In the laboratory the samples were placed in five groups. A brief description of these are as follows: Group A - is a Silt with a trace of organics and fine sand. It is highly frost susceptible and non-plastic. This soil group forms the top layer of mineral soil in several of the test borings. It grades or changes to Group Cra sandy silt:. Continental Land Investments, April 15, 1980 Page Two Ltd. Group B - is a fine Sand having 40 to 50 percent silt. The silt is non-plastic. Because of the high silt content and the uniform fine sand, this soil is also highly frost susceptible (F-4). Its Unified Classification is SM. Group C - is the predominate soil found. It is a Sand~ coarse Silt. The grain ~ize distribution curve is shown on F-~re 1. It is only slightly plastic having a plas- ticity index of 1.7. Its Unified Classification is ML and the frost classification is F-4, highly frost susceptible. Group D - is a Silty Gravelly Sand. Only one layer of this soil was encountered. In Test Hole 4 it occurred from two to four feet depth. The sand contains 10 to 15 percent silt and 20 percent fine to medium gravel. It has a .frost classification of F.-2 and a Unified Classification of SM. Group E - is a fine Sand with a trace of silt. This soil was found on Lot 14 at a depth of two to 12 feet and Boring 2 from a depth of 12 to 15 feet. Its Unified Classifica- tion is SP/SM and the frost classification varies from NFS (non-frost susceptible) to F-2. No ground water was encountered in any of the holes, though the drilling was accomplished during "spring thaw". The percolation test results are as follows: Lot 12 2.5 minutes/inch Lot 13 3.3 minutes/inch Lot 14 3.2 minutes/inch Lot 15 3.7 minutes/inch Based on criteria in the "Manual of Septic Tank Practice", U.S. Public Health Service Publication No. 256, the required absorption area in square feet per bedroom is 100 square feet for Lot 12 and 115 square feet for the other lots. We suggest that a minimum of 150 square feet per bedroom be provided on each lot since the soils are relative].y fine-grained and could tend to plug with continued use of the seepage system. Also, drain fields should be placed as high as possible on the lots avoiding the more low lying areas. The percolation tests were performed by placing a slotted PVC pipe in the test borings and filling the pipe and borehole with Continental Land I~nvestments, April 15, 1980 Page Three Ltd. water. After soaking the hole for 24 hours, the pipe was refilled and the percolation rate observed for one hour. The reported percolation rates are the lowest observed during this time period.

You have noted that separation distance between the end of the leach trench and closest edge of the pond was 66 feet at the time of your inspection. Because this pond has no outlet to other surface waters, the threat of contamination outside of the immediate area is low. Furthermore, this is an intermittent pond which get progressively smaller as the summer progresses. A dry testhole, drilled to a depth of 15 feet has alleviated any concerns that the septic system may be installed in saturated soils. A waiver of the septic tank to well separation has also been granted. This distance has been waived to 95 feet. Sincerely, Stephen S.

Perforated pipe was installed to the bottom of the hole which is located 16 feet south of the last standpipe in the soil absorption system. On Wednesday, August 13, 1986 the hole was inspected for water. No water was measured even though the area had received over 1-inch of rainfall during the prior 24-hour period.

OF HEAL1H & ENVIRONMENTAL PROFECTION 1 4 ~,~ fa~ ~--iln~/~ Di 1 s Dear Mr. Morris: By means of this letter I wish to request a waiver for the subject lot of the well - septic tank separation distance down from the required 100 feet to 95 feet, and of the absorption field surface water separation distance down from 100 feet to 60 feet. To assist you in your evaluation I am enclosing copies of the septic system as-built, the soil log, the well log, and a plot plan of the property. The well is located 97 feet west of the the closest septic tank cleanout and at a slightly higher elevation. The 163 feet deep well was drilled in 1981, at which time the static water level was 55 feet. On June 16 the static water level was et 98 feet, and steady pumping at 6,8 gpm caused a maximum drawdown to 104 feet. The drillers log indicates a silt & sand mixture between 0 and 85 feet, and between 89 and 130 feet. I would guess that at least portions of these strata have a high enough silt content to provide an effective barrier against downward percolation of surface water into the potable aquifer. In any event there is close to 100 vertical feet of non-saturated soil above the present static level of the aquifer. A water sample from the well taken on June 16 showed no contamination by coliform or other bacteria., In light of these facts, I believe the requested minor waiver of the well - septic tank separation distance can be justified. The sept:Lc system was installed in August of 1981, and no mention of any pond appears on the as-built, or in the soils test report done in April of 1980. On Juae 16, 1986 there was a marshy pond of approximately 80 feet in diameter located 66 feet east of the cleanout pipe at the end of the absorption trench, in the vicinity of the property line between lots 13 and 14. The owner reports that the pond does dry up later in the summer, however,it has a substantial size at the present time. The pond is in a natural depression with no outlet to a stream. The fact that it does not drain out can perhaps be explained by fine silt being carried to the bottom of the depression by runoff, and collecting there to form a semi-impermeable berrier. frost could also still be a factor. Seasonal I conducted an adequacy test of the septic system on June 16, 1986. At that time there was over 6 feet of fluid in the monitor tube at the end of the trench, with a surface elevation the same as in the septic tank. Addition of 100 gallons of water to the absorptiou trench caused the level in the trench and in the septic tank to rise 10 inches, however this water was able to be absorbed into the surrounding soil at a rate of approximately 60 gallons per hour which is an adequate rate for a three bedroom residence. At no time did effluent appear on the surface of the ground, nor was there any indication of it's having done so in the past. There is 4 or 5 feet of vertical drop between the ground elevation at the end of the absorption treuch and the present level of the pond. In an effort to determine whether any contamination from human sources is making it's way into the pond, I took a water sample from the edge of the pond nearest to the absorption pond to have tested for both fecal coliform and fecal streptococcus. If the ratio of these two is over 4.1, pollution from human sources will be indicated, and if the FC/FS ratio is less than 0.7 the source would be non-human. Since I will be out of town until July 12, I have requested the ].ab to send the results directly to you for your evaluation in conjunction with the other information contained in this letter. While it is unfortunate that the system was allowed to be constructed as it was, there are several considerations that can be raised in support of granting a waiver. As mentioned, the pond has no outlet; hence any pollution occuring there would not make it's way into flowing streams or recreational lakes. Should wastewater make it's way into the pond, the pond would tend to function as a treatment lagoon. Secondly, the lots in this subdivision are all large (typically an acre or larger - Lot 14 is approximately 1.5 acres); thus other pollution sources are widely dispersed. Finally, the very presence of the pond, and the fact that the static water level in the trench is as high as it is, indicates that the soils are tighter than the 150 sand indicated on the log; this will result in slower disbursement of effluent through the soil and louger retention time before it reaches the pond. Please review the above and the enclosures, and send your determination directly to the owner at the address indicated on the blue form, with a copy_:.~ ~t4~ Flattop Technical Services. Thank ~Ay~ .'
