This letter issues a Separation Distance Waiver for the requested reduction in the State’s minimum separation distance requirement between the source water well and septic system components as detailed in the submitted engineering plans and outlined below. Project Background This on-site wastewater disposal septic permit was installed in July of 2024 for the house located at 13900 Schubert Circle in Anchorage, AK and is shown in Figure 1. The original design of this residential septic system was designed outside of the 200-foot radii for the DeArmoun #2 community well. However, it was discovered during the record drawing process that the survey stakes were off and 2/3 of the septic tank is at 195-feet from the well and about 3.4-feet of one of the absorption trenches were installed within the 200-foot separation radius of the community well. The new septic tank is a 1250-gallon plastic tank with 20-inch manway from Infiltrator Water Technologies and 4-inch 304 schedule 80 PVC pipe was used (gravity system). Two absorption trenches were construction that were 50-foot long, 5-foot wide and 0.5-foot effective depth. Rigid insulation board was placed on top of both the septic tank and trenches. Each trench has two cleanouts and one monitoring pipe. The new septic system is at a lower elevation than the existing well and is sloped away from the well. The groundwater is approximately 90-feet below the ground surface and well is drilled to a total depth of 167-feet. A separation distance waiver was requested once this was discovered and the waiver is for: • 195 feet to new septic tank • 196 feet to northern absorption trench Septic System Improvements 2/13/2026 260213_DeArmoun B2L8 Septic System_211936_WA.docx Page 2 of 3 Figure 1: Constructed New Septic System at 13900 Schubert Cir in Anchorage AK. Separation Distance Waiver The separation distance waiver for encroachment of the source water well is approved based on the following design elements to maintain public safety: • Septic system is designed to slope away from the community well and is at a lower elevation • Septic system was tested for water tightness and had no leaks • Septic tank is plastic tank and has effective life span of 50 years • Vertical separation is approximately 80-feet from trenches to groundwater through silty sandy soils. • Shallow absorption trench with 2-inch rigid insulation board on top of drain field rock and 4-feet of cover Septic System Improvements 2/13/2026 260213_DeArmoun B2L8 Septic System_211936_WA.docx Page 3 of 3 Limitations and Appeal Process This waiver is limited to this project and its current site conditions. Any changes, constructed or natural, that affect the conditions to which this waiver was granted may void this waiver and the water or sewer may be required to be relocated to meet separation distance requirements. Approval of this waiver does not obligate the department to approve future waiver requests proposing the same design, is not an approval of omissions or oversights, and does not guarantee correctness of the functional design or waive the owner’s responsibility for continued compliance with state, federal, and local regulations. A person authorized under a provision of 18 AAC 15 may request an informal review of a contested decision by the Division Director in accordance with 18 AAC 15.185 and/or an adjudicatory hearing in accordance with 18 AAC 15.195 - 18 AAC 15.340. See DEC’s “Appeal a DEC Decision” web page https://dec.alaska.gov/commish/review-guidance/ for access to the required forms and guidance on the appeal process. Please provide a courtesy copy of the adjudicatory hearing request in an electronic format to the parties required to be served under 18 AAC 15.200. Requests must be submitted no later than the deadline specified in 18 AAC 15. If you have any questions regarding this waiver, please contact me at 907-269-8812 or email at kiana.eller@alaska.gov.

The attached site plan identifies the location of the home as well as the existing community well reserve, septic location and alternate site. The ground surface on the lot slopes steeply on the southeast side of the lot, but the slopes even out on the southwest side and are much milder. It is in that flatter area that the new septic system is located. There are no slopes greater than 25% within 50 feet downslope of either the primary or alternate site. Contours are shown on the site plan showing the grade and direction of flow. Stormwater drainage will not impact this septic system. The new trench will be constructed parallel to the slope as much as possible. Wells on this and adjacent lots are shown. No conflicts exist between this proposed system and any other well or septic system, whether on this lot or adjacent lots. The new system will be a minimum of 200' from the community well, more than 100' from surface water, and more than 5' away from the septic tank. The alternate site is located more than 6' away. Please refer to the attached test hole log, plan and profile pages for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.
