Anchorage, AK 99507 Reference: Septic system replacement for: Street Address: 19423 Wildwood Dr., Chugiak, AK 99567 Legal Address: Acre Lot 1, Skyline View Subdivision, Plat P-508, Anchorage R/D Property Owner: Jared Albright Re: Request for Permit To: Curtis Townsend, The Alaska Native Tribal Health Consortium, Div. of Environmental Health and Engineering, is assisting homeowner (Albright) with upgrading and replacing their existing onsite septic system. The existing septic tank and trench style drainfield are in failure mode, with reports from the local septic tank pumping company that the tank is not holding wastewater. We are proposing to replace the entire septic system, with two new sewer service lines (2 house connections), two sets of foundation double clean-outs, a new 1,500 gal, polyethylene septic tank by Infiltrator, and a new deep-trench absorption field. The new field will be built directly over the existing trench and will be longer and wider, and a little deeper. The existing trench is 2.5ft wide, by 6ft deep of sewer rock (about 11ft to bottom), and 34ft long (Reference current COSA in Muni electronic files.) The existing trench will be removed, to include 15” of soil on either side of the trench, 12” over the old trench, 12” under the trench, and 12” on either end, along with the contaminated sewer rock; and will be backfilled with new clean sewer rock. The new trench dimensions will be 5ft wide, by 12ft deep (with 7ft of sewer rock and 5 ft of soil cover), and be 52ft long. Absorption field design criteria • 4-bedroom house. • Design flow rate: 150 gal/day/bedroom. • Total design flow: 600 gal/day. • Note: There were 3 test holes dug on this site. One in 1982, one in 2016, and one by ANTHC in 2025. • Test hole #1 (1982) (O&E Engineering & Development Co (Oyster and Ellis) - soil type from 4ft to 12ft is: sand with gravel and cobbles up to 24” in size – Field classification: Page 2 of 9 SP. The Test Hole was dug to 16ft. It was located down at the bottom of the hill, probably with the intent of using the upper portion of the lot for the well and house. • Test hole #2 (TH 16-1) (2016) (ArcTerra Consulting, Inc) - soil type from 2ft to 15ft is: moderate dense soil, with traces of silt and cobbles to 1’ – Field Classification: SP/gp- gm-sm. Test Hole was dug to 15ft. • Percolation test TH#2 (TH 16-1) (4-12-16) (ArcTerra Consulting, Inc) = Percolation rate is: 1.73 min/in • Test Hole #3 (ANTHC 10-24-25) – There were 3 samples taken in all, one at 4ft and one at 8ft with soil type being: “Well-graded gravel with silt and sand”, (GW-GM). The third sample was taken at 16ft with soil type: “Well-graded gravel with clay and sand” (GW- GC). Analyzed by Shannon and Wilson Geotechnical and Environmental Consultants 11-5-25. • Test Hole was dug to 17’ within 30’ of the proposed drainfield trench location. o However, upon completion of the design, the bottom of the new trench will be at an elevation of 489’. Which is about 13.5ft deep. In order to provide 6ft of vertical separation distance, the test hole would need to be down to an elevation of: 489’ - 6’ = 483’ This would require a test hole depth of 502.5’ – 483’ = 19.5’, based on the highest point of the existing grade along the trench. (The yard slopes a bit along the alignment of the trench and drops about 2ft along the 52’ run. In order to verify that there is no impermeable layer within 6ft of the bottom of the trench, evaluations were made to the well logs on both this lot (Lot 1) and the neighboring lot (Lot 2). From these two reference documents, it can be seen that there is no bedrock, nor an impermeable layer, down to 19.5ft. Figure 1 - Well Log from Lot 1, Skyline View Subdivision – showing no bedrock to 19.5ft. Page 3 of 9 Figure 2 - Well Log from Lot 2, Skyline View Subdivision – showing no bedrock to 19.5ft. • Percolation test (ANTHC 10-24-25) = Percolation rate is: 4.0 min/inch. (There was a mis-calculation on the earlier form of the perc test, which has been since corrected.) o The percolation test was performed at 3-4ft deep, to meet OSHA requirements for Competent Person Excavation Requirements and Confined Space Entry rules, which begin at 4ft. However, the Muni does require the percolation test to be taken in layer of soil where the absorption trench will be located. In the case of Albright, the sewer rock portion of the trench begins at 5ft and extends down to 12ft. The formal soil analysis from Shannon and Wilson, shows fairly similar and consistent materials at 4ft, 8ft, and 16ft depths. The test holes from O&E Engineering and ArcTerra also show similar soil types in this vicinity. The ground appears to fairly consistent down to 17ft. The ArcTerra percolation test was performed at a 4ft to 5ft depth and had a similar percolation rate to the ANTHC percolation rate (1.7min/inch versus 4.0 min/inch). The red clay layer was encountered about 4ft down, and varied a bit, but does show a distinct layer (see photo). The Percolation Test was performed into this layer, which resulted in the 4.0 min/inch perc rate. This would also explain why the perc rate was a bit slower than the percolation rate that ArcTerra determined (1.73 min/in). However, the Page 4 of 9 soils under this layer are in more porous material and is where the treatment trench will be located. The percolation rate would be assumed to be somewhat faster, under this layer. The subsequent strata’s at 4ft, 8ft, and 16ft were mostly well-graded gravel with silt and sand, with some clay showing up deeper in the hole. o However, for design purposes, the more conservative loading rate used in the design calculation also mitigates and offsets the percolation test being run at 4ft. Based on the soil type, photos, and percolation rates, it is reasonable to assume that the rate would not be that much different another 1’ or 2’ deeper, and probably better (faster). • No groundwater water encountered at any test holes • The existing system has failed (backed up), as has the septic tank (not holding wastewater) which was identified by local septic tank pumping company • The new system will be a deep-trench system. • There is a steep slope of 72% in the back yard of this site. The existing system and proposed new system is within 50ft of a slope greater than 25% over 10ft vertical. The slope is also within 100ft of a slope greater than 46%. o However, there is an allowance from the municipality that allows for a reduced minimum horizontal distance if the system can be 35ft or more from a point that Figure 3 - Photo of Test Hole from ANTHC TH, 10-24-25 – showing soil type and band of clayey material at 3ft. Page 5 of 9 is 2.5ft above the discharge piping, and runs an artificial line of slope 25%, that intersects the existing slope. In this case, the existing slope is 72%. When the topography and cross section is calculated, we are able to meet 35ft from the closest point to the bluff. Which for the most part, also coincides with the existing trench. See below Profile Diagram on the Slope (Figure 4). o Below is the scaled drawing indicating that the trench will meet the Muni modified requirements to be within 35ft of the intersection of the existing slope with an artificial 25% slope. • Figure 4 • The plan is to place the new trench over the existing trench. The existing trench is 2.5’ wide, by 6ft deep of sewer rock, and 34ft long. The new trench is will be 5’ wide, and have 7ft of sewer rock, and be 52ft long. This allows for the removal of an extra 15” of soil on either side of the trench, 12” above the field, 12” underneath, and 12” on either end. This will remove all contaminated soil associated with the site, and will be hauled off-site to a suitable disposal location. • The new trench was also based on the following calculations. • The GW-GM type soils, backed by the percolation test would require a loading rate of 150 sq ft/ bedroom. Therefore a 4-bedroom house would require: 4-bedrooms * 150 sq ft/ bedroom = 600 sq ft. Initially, the new trench was based on 6ft of sewer rock. So, 600 sq ft / 6ft * 2 sides = 50 ft long. However, with the addition of the extra material, the trench is 7ft deep. If we keep the 50ft long distance, the resulting treatment area is: 7ft * Page 6 of 9 2 sides * 52ft = 728 sq ft. This is a loading rate per bedroom of: 728 sq ft/4 bedrooms = 182 sq ft per bedroom, which is reasonable for these soils, as they do contain some silts in them, and a higher loading rate is an appropriate consideration. • This also provides a loading rate of 4-bedroom * 150 gal/ day / bedroom = 600 gal/day. 728 sq ft / 600 gal/day = 1.2 gal/ sq ft / day. Which is a little high for sandy soils. However, this does not account for the bottom 5ft of treatment area, which is not typically used in the sizing of a deep trench, but does add additional treatment. An effective overall treatment area is 728 sq ft, plus, 5ft x 52ft = 260 sq ft. = 728sq ft + 260 sq ft = 988 sq ft. Therefore 600 gal/day / 988 sq ft = 0.61 gal/sq ft/day; which is consistent with the values that Conway and Tyler from the University of Wisconsin, recommend in their onsite wastewater treatment systems manual for infiltrative rates for a coarse sandy loam material. • The deep-trench will be 7ft deep, by 5ft wide, and be 52ft long. • The discharge piping from the septic tank will be 50 ft of perforated 4” PVC pipe. • The pipe will be covered with 10 ea, Quick5 Infiltrator chambers with end caps, to protect the orifices and piping. • The chambers will be covered with non-woven geotextile fabric. • The chambers will also be covered with 4” of rigid boardstock insulation. • There will also be 5ft of soil cover over the trench. • The septic tank will be a 1,500 gallon polyethylene septic tank made by the infiltrator company, as we need 2 inlets into the tank, and this tank has the ability to have side inlets. The septic tank will be covered with 4” of rigid boardstock insulation. Note: There are 3 risers that can be installed for this tank, with the middle riser allowing access to the baffle that separate the primary chamber from the second chamber. • There will be two sets of double clean-outs at the foundation, as there are 2 separate wastewater lines coming from the house. (there was a mother-in-law apartment added to the house, which had brought the bedrooms up to 4). Below is a copy of the Civil Design Sheet showing the layout of the system. This is from the Plans-for-Agency -Review (PAR) set for AKA-24-ANC – Albright Site. The set will be converted to an Issued-For-Construction (IFC) set, once the Muni permit is received and any changes required or recommended are incorporated. The following Figures are excerpts from the Engineering Planset, Plans-for-Agency-Review (PAR), AKA-24-ANC for the Albright Site. (To be converted to Issued-For-Construction (IFC) once the permit is received. Page 7 of 9 Figure 5 – Civil Overview Sheet (1:40 Scale) Figure 6 – Civil Design Sheet (1:20 Scale) Page 8 of 9 The design of this system conforms to standard engineering design practice and meets the intent of Municipal Wastewater code AMC 15.65. • A test hole was dug within 30ft of the proposed drainfield and the soils analyzed by Shannon and Wilson Inc, in November of 2025, and a perforated monitoring tube left in place to record groundwater over a 7 day period. (the pipe has since been removed). • The percolation test was performed by an ANTHC field technician under the direction of an engineer, in October of 2025. • There are no surface waters impacted by this design. • The topography of the site is mostly flat, around the house, and there is about a 4ft rise to the north side of the lot and a 8ft drop toward the neighbor to the south, and a steep 72% incline along the entire back of the lot, over 30ft down. • There is no violation of separation distances other than the Steep Slope Reduction Allowance. • The sewer service line, in order to bring in the 2 lines from the house, and use conventional fitting angles, will not have the full 10ft of uninterrupted pipe in front of the septic tank, which has since been reduced to 5ft per DEC. In order to get the two lines to enter the tank, with the least amount of plugging issues, there will be an angle of 22.5 degrees about 6ft from the inlet of the tank, at 2% slope on the incoming 2nd line (which enters from the front end of the septic tank. The 1st (and main) line has a straight shot into the tank of 16ft at a 2% slope. Both service lines meet both Muni and DEC requirements. • The residential well on this lot is protected by the 100ft horizontal separation distance from the septic system, but has shown high Nitrate levels in the past (11.1 mg/l - 2016). • No neighboring wells are in the vicinity of the proposed absorption field. o A field survey was conducted of the lots surrounding Acre Lot 1, Skyline View Subdivision and a review of the Muni COSA’s and the State’s WELTS database was performed. There are no residential wells within 100 ft of the proposed onsite septic system for Acre Lot 1. • The design of the absorption field will not cause surface water ponding or surface water run-off, to run onto neighboring lots. • The design of this system adequately protects public health.

THE EXISTING SYSTEM AND NEW SYSTEM IS WITHIN 50' OF A SLOPE GREATER THAN 25% OVER 10' VERTICAL. THE SLOPE IS ALSO WITHIN 100' OF A SLOPE GREATER THAN 46%. ·HOWEVER, THERE IS AN ALLOWANCE FROM THE MUNICIPALITY THAT ALLOWS FOR A REDUCED MINIMUM HORIZONTAL DISTANCE IF THE SYSTEM CAN BE 35' OR MORE FROM A POINT THAT IS 2.5' ABOVE THE DISCHARGE PIPING, AND RUNS AN ARTIFICIAL LINE OF SLOPE 25%, THAT INTERSECTS THE EXISTING SLOPE. IN THIS CASE, THE EXISTING SLOPE IS 72%. WHEN THE TOPOGRAPHY AND CROSS SECTION IS CALCULATED, WE ARE ABLE TO MEET 35' FROM THE CLOSEST POINT TO THE BLUFF. WHICH ALSO COINCIDES WITH THE EXISTING TRENCH. ·THE PLAN IS TO PLACE THE NEW TRENCH OVER THE EXISTING TRENCH. THE EXISTING TRENCH IS 2.5' WIDE, BY 6' DEEP OF SEWER ROCK, AND 34' LONG. THE NEW TRENCH IS WILL BE 5' WIDE, AND HAVE 7' OF SEWER ROCK, AND BE 52' LONG. THIS ALLOWS FOR THE REMOVAL OF AN EXTRA 15” OF SOIL ON EITHER SIDE OF THE TRENCH AND 12” UNDERNEATH AND 12' ABOVE. THIS WILL REMOVE ALL CONTAMINATED SOIL ASSOCIATED WITH THE SITE, AND WILL BE HAULED OFF-SITE TO A SUITABLE DISPOSAL LOCATION. ·THE NEW TRENCH IS BASED ON THE FOLLOWING CALCULATIONS. ·THE GW-GM SOILS, BACKED BY THE PERCOLATION TEST WOULD REQUIRE A LOADING RATE OF 125 SF/BR (UPSIZE TO 150 SF/BR). THEREFORE A 4-BEDROOM HOUSE WOULD REQUIRE - 4 BR * 150 SF/ BR = 600 SF. INITIALLY, THE NEW TRENCH WAS BASED ON 6' OF SEWER ROCK. SO 600 SF / 6FT * 2 SIDES = 50' LONG. HOWEVER, WITH THE ADDITION OF THE EXTRA MATERIAL, THE TRENCH IS 7' DEEP. IF WE KEEP THE 50' LONG DISTANCE, THE RESULTING TREATMENT AREA IS: 7' * (2 SIDES) * 52' = 728 SF. THIS IS A LOADING RATE PER BEDROOM OF: 728 SF/4 BR = 182 SF/BR, WHICH IS REASONABLE FOR THESE SOILS, THAT DO CONTAIN SOME SILTS IN THEM. ·THIS ALSO PROVIDES A LOADING RATE OF 4 BR * 150 GAL/DAY/ BR = 600 GAL/DAY. 728 SF / 600 GAL/DAY = 1.2 GAL/DAY/SF. WHICH IS A LITTLE HIGH FOR SANDY SOILS. HOWEVER, THIS DOES NOT ACCOUNT FOR THE BOTTOM 5' OF TREATMENT AREA, WHICH IS NOT TYPICALLY USED IN THE SIZING OF A DEEP TRENCH, BUT DOES ADD ADDITIONAL TREATMENT AREA. AN EFFECTIVE OVERALL TREATMENT AREA IS 728 SF PLUS, 5' x 52' = 260 SF. 728 SF + 260 SF = 988 SF. 600 GAL/DAY / 988 SF = 0.61 GAL/DAY/SF; WHICH IS CONSISTENT WITH THE VALUES THAT CONWAY AND TYLER FROM THE UNIVERSITY OF WISCONSIN, RECOMMEND IN THEIR ONSITE WASTEWATER TREATMENT SYSTEMS MANUAL FOR INFILTRATIVE RATES FOR A COARSE SANDY LOAM MATERIAL. ·THE DEEP-TRENCH WILL BE 7' DEEP x 5' WIDE x 52' LONG. ·THE DISCHARGE PIPING FROM THE SEPTIC TANK WILL BE 50' OF PERFORATED 4” PVC PIPE. ·THE PIPE WILL BE COVERED WITH 10 EA, QUICK5 INFILTRATOR CHAMBERS WITH END CAPS, TO PROTECT THE ORIFICES AND PIPING. ·THE CHAMBERS WILL BE COVERED WITH NON-WOVEN GEOTEXTILE FABRIC & 4" OF BOARDSTOCK ·THE SEPTIC TANK SHALL BE 1500 GALLON POLYETHYLENE BY INFILTRATOR COMPANY WITH TWO INLETS, AND SIDE INLET UTILIZING THE OPTION. COVER TANK WITH 4" RIGID BOARD INSULATION. ·THERE WILL BE TWO SETS OF DOUBLE CLEAN-OUTS, AS THERE ARE 2 SEPARATE WASTEWATER LINES COMING FROM THE HOUSE. (THERE WAS A MOTHER-IN-LAW APARTMENT ADDED TO THE HOUSE, WHICH HAD BROUGHT THE BEDROOMS UP TO 4).

Name of Firm GARNESS ENGINEERING GROUP, Ltd. Address 3701 E. TUDOR ROAD, SUITE 101 • ANCHORAGE, AK 99507 Engineer's Printed Name JEFFREY A. GARNESS, P.E. Engineer's Comments: In conducting this evaluation, GEG, LtD. attempted to provide a thorough, conscientious engineering analysis of the system In accordance with ADEC and MOA DSD Guidelines 8 Regulations. The reported results described the performance of the system under the conditions encountered at the time of the test, and separation distances measured to readily Identifiable features. The operational life of all wells and septic systems depend on the local soils condition, groundwater levels that may fluctuate during the year, and the water usage of the family being served by the system.

This inspection revealed a nitrate concentration of 11.9 milligrams per liter (mg/L) was reported for the property's well water sample. The Environmental Protection Agency (EPA) has established a maximum contaminant level (MCL) of 10.0 mg/L for public drinking water systems. While private wells are not subject to this regulation, EPA standards are based on existing health information and can therefore be used to gauge the relative quality of water from private wells. Please see the attached "Nitrate Fact Sheet" for important information regarding nitrate. This advisory must be attached to all copies of the subject Certificate of On - Site Systems Approval. N-1-2006 06:18A FROM: Y TO: 3383246 Aarow Pomp & Well Service L.L.C. (907) 346-9355 Well Work Regarding high nitrate levels at 19423 Wildwood Drive. Well camera was sant down to 50 feet with no broken welds or perforadons. Piths depth Is 10 feet below top of casing. We were only able to drive our grouting pipe to a depth of 15 feet due to larga rocks. We tried four diftent spots and that was the deepest we were able to go due to the amount of rooks. We pumped In excess of 140 gallons of grout slurry with none coming to the surface. It is my belief that R then was a surface water problem with this well it Is not any longer. Brian R.

Septic Symern Adequaa & Well Flow Test Test Procedure & Results: The well was pumped at a constant rate while an acoustic sounder monitored the draw down. At the beginning of the test, the static water level was measured at 60' below top of casing. At a pumpin; rate of 4.33 gallons per minute, the water level dropped only 4' to 64' and remained in the range of 63-64' for the duration of the test, recovering within minutes after the flow was stopped. Water samples were taken and found satisfactory with the exception of high nitrates (see attached). The Municipality of Anchorage requirement for well flow is 150 gallons of water per bedroom per day. This well exceeds this requirement. JR's pumped the 1,250 gallon septic tank prior to testing. At the beginning of the septic adequary test, 3.7' of standing fluid was present in the monitoring tube. A total of 600 gallons were added to the on-site wastewater absorption trench and the fluid levels rose 025'. Within minutes after adding the water, fluid levels returned to the pre-test level. The Municipality of Anchorage regwires an absorption rate of 150 gallons of water per bedroom per day. This septic system meets this requirement. The assessment of the condition of the well and septic applies only to the conditions as of the day tested. The flow and absorption rates may change due to subsurface conditions that may not be observed from the surface, changes in the land use, water usage and other factors. 05-25-06 I4:47 FROM-Pudential Jack White Eagle River 9016896/99 T-ddd P.004/008 F-621 Skyline View Lot I May 22, 2006 T Peee2 ort If you have any questions regarding the referenced property's on-site water and wastewater system or testing procedures, please contact me at 696-6111/FAX 696-8111. Respectfully, ICM Engineering, Inc. Attachments: SGS Water Analysis Note: The operational life of all septic systems depends on the local soil conditions, groundwater levels that may fluctuate during the year and the water usage of the family being served by the system. These conditions are outside the control of the evaluator of this septic system. Therefore we can not give any estimate of how long this system will function satisfactory for current or future occupants. All septic systems ultimately fail. Some systems last 15-20 years or longer, while others fail after less than 5 years.
