The attached site plan identifies the location of the home as well as the wells and septic location. No conflicts exist between this proposed system and any other wells or septic system, whether on this lot or adjacent lots. We are replacing the septic tank with the same size designed for 3 bedrooms. In addition to the tank replacement, we are specifying some repairs to the septic pipes , some of which have been damaged, frost jacked, or otherwise needing fixed to allow for adequate testing of the septic trench. The new septic tank will be a minimum of 100’ from all wells and surface water. Please refer to the attached plan for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.

Box 196650 Anchorage, Alaska 9951%6650 Subject: CONDITIONAL HAA for Private Well & Septic System. T12N, R3W, Sec 27, Lot 47 To whom it may concern: The subject lot has a 3 bedroom house on it which is se~wed by a private well and septic system. The results of the field investigation and adequacy tests are summarized as follows: A. WELL: On the clay of our inspection (9/10/97) the static level was 85 feet below the top of the casing (BTC). Water was pumped from the well at an average rate of 8.45 gpm for 71 minutes (600 gallons). The maximum drawdown achieved during the test was 4 feet, indicating that the well was recovering as fast as the water was being pumped out. Based upon this data it was determined that the capacity of the well exceeds the Municipal requirements for a 3 bedroom house (450 gallons per day). B. SEPTIC TANK: Tile existing septic tank was installed in November of 1978 (approx. 19 years old). According to the M.O.A records, it is 1000 gallons, has two compartments and is made of steel. Most tanks of this type have a structural life of approximately 20-25 years. No warrantee is made regarding the future life of the septic tank. C. SEPTIC SYSTEM WAS RE.HJVENATED USING THE TERRALIFT PROCESS: The septic system was initially found to be operating in a surcharged condition. The trench was Terralifted on 9/15/97 by Alaska Drainfield Restoration (Jerry Leach). D. SEPTIC SYSTEM ADEQUACY TEST: On the day of the adequacy test (9/24/97) the monitoring tube had 8.5 inches of liquid in it. Water was introduced into the clean-out at a rate of 8.45 gpm for a total of 71 minutes (600 gallons). This caused the water level to rise 19.25 inches, to 27.75 inches, which corresponds to 31.2 gallons per inch. During the first fourteen minutes of the recovery period the liquid level dropped 7.5 inches, indicating a recovery of 234 gallons. Based upon this data, it was determined that the absorption rate of the trench exceeds 450 gallons per day, as required for a 3 bedroom house. NOTE: The adequacy ora septic system is influenced by numerous factors, #tc&ding, but not limited to, seasonal swtface water infiltration, g~wundwater variation& septic aystem maintenance ~'equency of septic tank pumping, usage of biolo~cal additives), condition of drain pipe and pipe jomts (which can be damaged by seismic activity and deteriorate with age), type of swbstances deposited in septic system (cigarette butts, sanitary napMns, misc. objects), and the amoimt c~'water being introduced on a conanual basis. Consequently, the reswlts qf this adequacy tesl are on& valid for the sT)ecific day of the tesL P)trthermore, because of the limited nature of this' investigation, il is' possible that there are hidden defects' which may not have been detected No warrantee is made regarding the fitture pe¢fot~ance of this well or septic aystem E. WATER/SEWER SERVICE TO GARAGE: It is my understanding that, in the past, there was water service to the garage, and a toilet inside the garage. Per the property owner (Dan Church), the water service is shut off, and the toilet is no longer operational. The separation distance from the abandoned water selMce line to the septic tank and sewer se~Mce line is unknown. The separation distance should be unimportant unless the future owner chooses to reactivate the water service line. F. CLOSING: We are requesting the issuance of a conditional HAA, with the stipulation that the septic system be retested 30 days after the new occupants move in. Based upon the soils data for this lot, and the adjacent lots, and the space constraints, there appears to be adequate room to install a new septic system should the existing system fail to pass the retest. There does not appear to be any health/sanitation concerns associated with granting the ~:onditional HAA. If you have any questions, please contact me at 337-6179, 1-800-481-1162.

Box 196650 Anchorage, Alaska 99519-6650 Subject: HAA for Private Well & Septic System. T12N, R3W, Sec 27, Lot 47 To whom it may concern: A conditional HAA was applied for previously this month. The intent was to retest the septic system (30 days after it was Terralifted) and obtain an non-conditional HAA. Since the HAA package was submitted, the 30 day waiting period has expired, and we have retested the septic system. The results are summarized as follows: SEPTIC SYSTEM ADEQUACY TEST: On the day of the adequacy test (10/15/97) the monitoring tube had 10.5 inches of liquid in it. Water was introduced into the clean-out at a rate of 7.82 gpm for a total of 66 minutes (516 gallons). This caused the water level to rise 15.25 inches, to 25.75 inches, which corresponds to 33.8 gallons per inch. One-hundred & ninety-seven (197) minutes later the water level had dropped 12.75 inches, indicating an absorption of 431 gallons (2.19 gpm). Based upon this data, it was determined that the absorption rate of the trench exceeds 450 gallons per day, as required for a 3 bedroom house.

Dear Dan: The subject property (Lot 47) has a 3 bedroom house, served by a private well and septic system. The well was drilled on 8/22/78, after the crib was constructed on Lot 46. The well is 99.5 feet from the crib clean-out. The dimensions of the crib are unknown, so it will be assumed that the crib sidewall is only 90 feet from the well. At this time, we are requesting that the required separation distance from the well to the crib be waived to 90 feet. Justification for this waiver is summarized as follows: GENERAL: Attached is a topography map showing the general contours in the area. Shooting the slope from the well to the crib with a clinometer, indicated that the crib was downhill from the well at a slope of approximately 2%+. In short, surface overflow from the crib would not flow towards the well. The other potential path of contamination would be subsurface. Analysis of this contamination potential will be evaluated based upon the ADEC point system. ADEC WAIVER, POINT SYSTEM LVALUATION. Geological: The only well log on file at DHHS was for Lot 47. A copy of the log is attached. The wells on the adjacent properties appear to be undocumented. Based upon the log for Lot 47, no bedrock was encountered to a depth of 152 feet, and static water was 86 feet BTC. On the day of the well test (9/10/97) the static water was 85 feet BTC. In short, the bedrock profile does not appear to be a consideration, and the groundwater supply is quite deep. a. Distat~ce fi'om the bottom of the crib to grouttdwater (85foot static level in well): The bottom of the crib is approximately 10 feet below grade. The separation distance fi'om the bottom of the crib to the static water in the well for this lot is approximately 75 feet. This corresponds to 5.8 points. b. Soil sorhtion below the crib: According to the well log (lot 47), the geological profile is primarily a mix of silt, sand, and gravel, throughout the entire boring depth. I am going to assume a point value of 0 for the gravel, 1.5 for the sand, and 3.5 for the silt. In addition, it will be assumed that each of the soils exist in equal parts (33% gravel, 33% sand, 33% silt). This corresponds to a point value of 1.7, calculated as tbllows: (.33(0) ~ .33 (1.5) + .33(3.5)) = 1.67. c. Soil petwteability below the crib: I assumed the entire profile was sandy gravel, which corresponds to a point value of 0.9. d. Water table gradient: When performing the well adequacy test (pumping at a rate of 8.45 gpm for 71 minutes) the drawdown was only 4 feet. The hydraulic gradient, due to drawdown, from the septic system to the well, is negligible (approximately 4%). This corresponds to 2.7 points. e. Horizontal separationfi'om well to crib: Given a 90 foot separation distance, the point value is 2.6. Total Points: 13.7 According to the ADEC waiver guidelines, a point value 12-16 indicates no bacterial contamination is possible, and that chemical pollution (from household sources) is unlikely. Recent water sampling/analysis (9/10/97) found no bacteria, and nitrate levels of .876 mg/l. Copies of the lab results were submitted with the Health Certificate package. This encroachment has existed for over 19 years, and the well water quality has not been compromised. Given these facts, it is my recommendation that the requested waiver be approved.
