Box 196650, Anchorage, Ak 99519-6650 (907) 343-7904 Ref: Proposed Initial Septic System & Private Well for Eklutna Heights Subdivision; Block 1, Lot 10A (West Portion) To whom it may concern: The subject lot is currently vacant and has no water or sewer service. The owner is planning to build a four (4) bedroom duplex on the property that will be served by a septic system and well. We are proposing that a 1250 gallon septic tank and a deep trench type drainfield be installed. A test hole was excavated on the property. The drainfield is designed around the 30 foot radius of this test hole. We are also proposing to have a well drilled on-site to serve the proposed duplex. Attached is a site plan showing neighboring lots and separation distances from the proposed well. All necessary waivers have been approved by ADEC (see attached). Comments regarding the design are summarized as follows: We are unaware of any adverse impacts that the well and septic would have on any neighboring wells or septic systems. '1. SOILS: See the attached logs which show the soil classifications, groundwater monitoring, and the percolation test results. 2. DRAINFIELD DESIGN: See attached design drawing for drainfield specifications. 3. SURFACE WATERS: There are no surface waters within 100 feet of the proposed septic system. 4. TOPOGRAPHY: The average topography in the vicinity of the drainfield is relatively flat. We are unaware of any adverse impacts this installation would have on adjacent wells or septic systems. If you ave any questions, please contact us at 337-6179. Thank you for your assistance. // Oeffre ~. ~arh~s.~ P.E., MS. Presk ~ '~ 3701 E.

Waiver Approval of 120 feet: Septic System Lot 10A, Block 1, Elduma Heights S/D to Class C well on Lot 9A, Block 1, Ekluma Heights Subdivision. Dea~ M~. Gsmess, On December 19, 2012 this office received two separation distance waiver requests associated with the proposed septic system located on Lot 10A West, Block 1, Eldutna Heights Subdivieion. The construction of a new septic system on Lot 10A (serving a duplex) cannot be completed without encroaching on the t~quired separation distances of two Class C well~ located on adjacent lots. Information was provided on the adjoining eZlo~s C wells to allow the assessment of the potential risk posed by the septic system on Lot 10A. Howevex, insufficient information on lot development on LOt 9A or Lot llA was provided to support the approval of any other aspects, including any other needed Waivers, a~sociated with these wells. Nor was may approval associated with these adjoining Class C wells requested. Waiver Condition~ and Determination Based on an evaluation of the available information, the potential for contamination due to the lesser sepax'afion distance between the Class C wells and the septic system does not appeax to be significant. Separation distance waivers between the wells and septic system on Lot 10A axe summarized below: ~l/aiverl:-Class C Well oa Lo~lock-l-Etduhi~ lleights Septic system on LOt 10A, Block 1 Eklutoa Heights Subdivision to Class C well Lot 9A, Block 1 Ekluma Heights Subdivision (serving a six bedroom mplex) The separation distance reqmred by regulation is 150 feet. The sepaxafion distance t'equested and approved is 100 feet. 1. Although there was no indication of well grouting on the well log submitted for Lot 9A, the well shows a depth of 155 feet and a confining layer of silt and clay that may mitigate potential contamination. 2. Lab results on water taken from the well on Lot 9A show nitrates present, but below the MCL level 0.68 mg/L present, a maximum of 10 mg/L allowed). 1B0205EklutnaHeightsSOBlock1[0t10AWest218804FO.doc Page 1 of 2 blt.

The proposed septic system on Lot 10A ~h~!l be dedgncd and constructed withi~ State Standa~ls. 5. Due to development density with{n the subdivision, there a~e few options for the placement of this septic system.
