To whom it may concern, The subject property is served by a private well and a septic system consisting of a 1250 gallon septic tank and a seepage pit type drainfield. The septic system is in a state of failure and needs to be upgraded. We are proposing to install a Category III advanced treatment system consisting of a 1500 gallon S.T.E.P. tank, one AX -20 treatment pod, a secondary Orenco pump vault and a trench type drainfield. Design comments are summarized as follows: SOILS: One testhole was excavated on property. See attached soil log for soils profile, groundwater readings and percolation test data. SURFACE WATERS: There are no surface waters within 100 feet of the proposed septic upgrade. TOPOGRAPHY AND WAIVER: The topography in the area of the proposed upgrade is approximately 0-12% running south to north. We are proposing to install the drainfield perpendicular to the slopes in the area. Attached is a profile drawing showing that shows the feasibility to construct the system this way and keep the drainfield within the soils profiles that was perked and maintain proper soil cover. There are no slopes in excess of 25% within 50 feet of the proposed septic upgrade. LOT LINE WAIVER: Due to site contraints, we are requesting a 1+ foot lot line waiver to the east lot line. The adjacent septic system is over 10 feet from the lot line. A.D.E.C. WAIVER: As can be seen on the site plan, it is impossible to construct a new septic system on this lot without encroaching on the 200 foot radius of the Class A wells serving the neighborhood. A waiver package will be submitted to the A.D.E.C. shortly. This permit will be contingent on receiving this waiver for these distances. When we receive authorization from the A.D.E.C., we will forward it to you. 3701 East Tudor Road, Suite 101 *Anchorage, Alaska 99507-1259 Phone: (907) 337-6179 * Fax: (907) 338-3246 * Website: www.garnessengineering.com Page 2 oft I am unaware of any adverse impacts this installation would have on any surrounding wells or septic systems.

Trench to Seepage Pit Waiver. To whom it may concern, The design for the subject property proposes an upgraded trench that may encroach upon the separation distance required by MOA code (2x the effective depth). The exact boundary of the existing system is unknown. We request that you waive the distance from drainfield to drainfield to 5 feet. The following items are justification for this waiver: The replacement trench is being placed as shown to maximize distance to the public water source. This is being considered as more important than maximizing separation to a drainfield that will not be used concurrently with the replacement trench. Both drainfields will be served by an intermittently dosed Category III advanced treatment system. This will significantly minimize the risk associated with one drainfield influencing the other. Based upon the aforementioned facts, we believe there is minimal risk associated in granting this waiver. If you have any questions, please contact us at 337-6179.

Jeffery A. Gamess: 555 Cordova street Anchorage, Alaska 99501 Main: 907.269.3076 Fax: 907.269.7650 thomas.brannon6alaska.gov, File: Borealis Alpha PWSID: 2111708 Class: Community Source: Groundwater On April 15, 2015, this office received your submittal requesting a waiver of the State's minimum separation distance requirement between a community drinking water source and potential sources of contamination. This letter approves the requested reduction in the State's minimum separation distance requirement from 200' to 140' between the drinking water well serving the Borealis Alpha Public Water System, located in the cul-de-sac on the west end of Alpha Circle, and a proposed septic system located at Borealis S/D, Lot 7, this encroachment includes an Advantex septic treatment package at 140', an existing (now a reserve) drainfield at 160', and a proposed drainfield at 1701. Waiver Determination As indicated in your submittal, the septic system serving Borealis S/D, Lot 7 consists of a 1250 gallon tank and a seepage pit type drainfield installed on July 16, 1974, its replacement is now proposed. As with the original septic system, the location of proposed septic system fails to meet the State's 200' tniuimurn separation distance requirement between a community water system source and a wastewater disposal system. At its nearest, the septic system and its appurtenances are 140' from the well serving the Borealis Alpha P%VS. This well was believed to be drilled in 1974, however the associated well log couldn't be located. Static water level in the well was measured at 97' below the top of the casing on August 26, 2013. Well logs in close proximity to the subject well show lenses of slit, clay, gravel, and mixes thereof, and range in depth from 117' to 137. In addition to the proposed septic system to serve Borealis S/D, Lot 7, the well serving the Borealis Alpha PWS is also subject to several other separation distance encroachments. The septic system serving Talus West, Block 1, Lot 8 and Talus West, Block 1, Lot 9 received Separation Distance Waivers from this office on September 24, 2013 and July 24, 2014, respectively. Additional encroachments are summarized below: Note: After rmewgg this PWS's file, it is andear if the separation distance encroachments listed in Table 1 have or bave not been granted Separation Distance Waivers from this offue. While the approval of the requested separation distance waiver has included a wren, of'the eumuk Live effeas posed by all of the encmachments, it does not imp# thegranting of Separation Distance Waivers to the enemacbments listed in Table 1.

Mr. Jeffrey Garness, P.E. 2 September 16, 2015 The following additional items were taken into consideration as part of this waiver approval: 1. From February 2001 to January 2015, source water sampling results for nitrate -nitrite concentration rose from 0.79 mg/l to 1.89 mg/l. This suggests that the well may be minimally influenced by septic system exfiltration, decomposition of organic matter in soils; and/or erosion of natural deposits, however nitrate -nitrite concentrations remain well below the 10 mg/L Maximum Contaminant Level; 2. From February 2001 to June 2015, source water sampling results for total coliform and e. coli recorded one total coliform positive result (repeat samples were negative) and no e. 4nli positive results; 3. The proposed septic system is located down grade of the wellhead and is separated by the house, landscaping, and driveway grading; 4. The septic system has been in place for over 41 years without significant effects on water quality; 5. The location of the septic system maximizes horizontal separation as grade, configuration, and existing utilities allow; and 6. The well accesses a presumed confined/semi-confined aquifer. Based on an evaluation of the available information and in accordance with the State's Drinking Water Regulations, 18 AAC 80, a Separation Distance Waiver for the proposed septic system located at Borealis S/D, Lot 7 is issued.

GARNESS Date (Rev. 11M) #AECC884 Carroll, Rebecca M From: David Garness <David@garnessengineering.com> Sent: Friday, February 16, 2018 10:47 AM To: Ecklund, Timothy 1; Carroll, Rebecca M. Cc: Jeff Garness Subject: Borealis; Lot 7 Hello, The justification for the passing result for the subject lot (Borealis; Lot 7) are as follows: 1. 833 gallons were introduced into the drainfield 2. This caused a rise of 32 inches in the monitoring tube (70-38) 3. This equated to 26 gallons/inch of rise in the drainfield (833/26) 4. Over a 120 minute period the drainfield dropped 16 inches (70-54) 5. 26 inches of drop in the dranifield equates to 416 gallons (26 gallons x 16 inches) 6. This equates to an absorption rating of 3.46 gallons/minute (416 gallons/120 minutes) 7. This equates to an absorption rating of 600+gallon/day, which meets the MOA requirements If you have any questions regarding these results, please feel free to call or email.

Records indicate the tank was placed and the absorption crib constructed in 1974 to serve a four bedroom home. Soils tests performed at the time estimated the absorption rate at 220 square feet per bedroom. The crib was constructed with an effective absorption area of 819 square feet which is slightly less than the '880 square feet required. The system was approved as constructed and has been in service since that time. Our initial probe of the crib indicated a standing water depth of 63" with a total depth of the crib of 108". Water was then injected into the crib to determine the absorption rate over a 24 hour period. The water level rose rapidly to the top of the crib after 400 gallons of water had been added. The test was then halted as water was starting to backflow into the septic tank. Three hours later the water had receded to the 83" level. Additional water was then added to the crib bringing the level again to the top. The water level was then checked the following day and found to have receded to the 83" depth. It appears therefore, the crib is capable of absorbing more than 600 gallons of water per day. The surge capacity, however, is limited to 400 gallons. The normal life of a septic system is from 8 to 12 years and can be less depending on the type of system and quality of soils in which it is constructed. Your system is now more than 25 years old and showing signs of failure. It is difficult to estimate the remaining useful life of the system, but due to the limited surge capacity it may be no more than 2 to 4 years. Sincerely, Michael E. Anderson. P.E.

Box 240773 Anchorage, Alaska 99524 Telephone: (907) 269-7696 Fax: (907) 269-7650 November 12, 1999 Subject: Lot 7, Borealis Subdivision, Separation Distance between Class A public water system source well and wastewater disposal system; ADEC Project Number: 704; Review Dear Mr. Anderson: I have completed my review of your November 8, 1999 submittal regarding the above -referenced project. I could not find any information in the Department's files that showed when the Borealis Alpha Class A public water system (PWSID Number 211708) was classified as a public water system. In the historical information that I have on separation distances, the existing separation distance between the existing source well and the wastewater disposal system located on Lot 7 meets the separation distance for semi- public water systems. Since the wastewater disposal system located on Lot 7 has passed a recent adequacy test, I believe that your request is reasonable. Therefore, this Department has no objection to the existing separation distance between the source well for Borealis Alpha Class A public water system (PWSID Number 211708) and the wastewater disposal system located on Lot 7, Borealis Subdivision. This letter of non -objection is valid as long as the existing wastewater disposal system located on Lot 7, Borealis Subdivision does not fail. Once any part of the wastewater disposal system fails, the home will need to be placed on a holding tank or a separation distance waiver will need to be applied for. The waiver request will need to include additional treatment to the wastewater stream and follow the submittal requirements found in either the State Wastewater Disposal or Drinking Water Regulations. Thank you for your cooperation and coordination with this Department. If you have any questions, please do not hesitate to contact me. Sincerely, Keven K Kleweno, P.E.
