The approved separation distance is 0.0 feet. In addition, your request for a waiver of the requirements that a test hole not be located closer than 5 feet from a drainfield and that test holes be presoaked prior to the percolation test have been approved. See engineer's waiver request letter and profile drawing for justifications. This waiver approval applies to the proposed absorption field only. Any future upgrade to the on-site wastewater disposal system will require all separation distances be met or another approval from this department. ❑ The affected adjacent property owner(s) have been given a 7 day notice regarding this waiver. ❑ Notarized letter(s) of nonobjection have been received from the owner(s) of the affected adjacent property. ® Adjacent properties are not affected by this waiver.

Three test hole were excavated on the property. The primary drainfield has been designed around the 30 foot radii of Test Holes #2 and #3. The reserve site has been designed around the 30 foot radius of Test Hole#1. We are proposing that a 1250 gallon septic tank and dual 5-wide shallow trenches be installed for this property. The proposed well is to be drilled as shown on the attached site plan. Comments regarding the design are summarized as follows: 1. SOILS: See the attached logs which shows the soil classifications, groundwater monitoring, and the percolation test results. The percolation rate for all test holes was 5 minutes/inch. Based upon the percolation rates, the allowable application rate for TH#2 and TH#3 is 1.2 gpd/sq.ft. To be conservative, we are proposing to use an application rate of 0.8 gpd/sq.ft. for this design. We are also proposing that a sand filter be used for this installation to comply with provisions in the proposed code for"steep slope" installations and to provide separation to bedrock. 2. DRAINFIELD DESIGN: See attached design drawing for drainfield specifications. 3. SURFACE WATERS: There are no surface water concerns within 100 feet of the proposed septic system. 4. TOPOGRAPHY AND SLOPE WAIVER: Topographical information provided, by Buku Saliz, RPLS, is shown on the site plan and design drawings. We have also provide a detail drawing which shows two different cross-sectional detail drawings. We are proposing to use the proposed revisions to the wastewater code for this installation. We have attached a copy of the "Steep Slope" disposal fields section for you review (pages 28 & 29 of 62). Based upon this code, Deep Trench and Wide Trench disposal fields may be installed on a slope greater than 25 percent, but less than 46 percent. Our proposed design utilizes Wide trenches, with a maximum effective depth of 6 inches, with the distribution pipe invert being less than 36 inches below the top of the natural organic layer, measured on the downhill side of the excavation (as stated in "Exception" in this code section). As can be seen on the profile drawing Page 3 of 3, we are proposing to excavate 3 feet deep(both on the uphill and downhill side of the trenches) and then import/place MOA sand to meet requirement #1 of this section of the proposed code. Given the soil porosity, it is reasonable to believe that there will be rapid downward movement (through the imported sand and insitu soil) until the effluent reaches bedrock, after which there will be some lateral migration 3701 East Tudor Road, Suite 101 *Anchorage,Alaska 99507-1259 Phone: (907)337-6179*Fax: (907)338-3246*Website: www.garnessengineering.com • Page 2 of 2 along the natural topography. This meets requirement#2 of this section of the proposed code. In addition to this, we have also revised our design to provide multple flow splitters and inlet points on the drainfields to insure even distribution to the drainfields. This will insure the flow is not concentrated in one or two areas in the drainfields and provide further justification for this waiver. There is no slope greater than 46%slope 100 feet downhill from the drainfields. Based upon these justifications, it is our opinion that we have provided sufficient information to grant this waiver. A majority of the drainfield will have 3:1 slopes around the entire perimeter of the drainfield except a small area on the south/southeast end to the lower drainfield. We are proposing the slopes be reduced to 2.5:1 as shown on the cross-section detail drawing. The entire mound will have 6" of topsoil placed over it and will be seeded. It is our opinion that there is minimal risk with the granting of this waiver. 5. DRAINFIELD TO TEST HOLE WAIVER: We are proposing to construct the new upper drainfield near/over the test pit for the TH#3 excavation. Given the test hole was backfilled with native material, was tamped down with the excavator bucket periodically during backfill, and that the 4" monitoring tube for the test hole will be pulled prior to placement of drainrock, it is our opinion that there is minimal risk with allowing a portion of the upper drainfield to be constructed over the test hole. Please require the removal of the test hole GWM tube as a "special provision" on the permit. 6. TEST HOLE PRESOAK WAIVER: We are requesting that the percolation tests for all the tests be evaluated/approved based upon the proposed wastewater ordinance, which does not require a 4 hour presoak for soils with percolation rates less than 60 minutes per inch. Four (4) recovery readings were taken with no change on the last 3 readings. We are unaware of any adverse impacts this installation would have on adjacent wells or septic systems.
