ARM Septic Services, LLC checked the monitoring tubes in the drainfield in April of 2019 and found them to be dry. In order to simplify the overall operation and maintenance of the system, we are proposing that this unit be permanently configured as a CAT II system. Our justifications are as follows: The receiving soil has a percolation rate of 20 minutes per inch. Given this percolation rate, a 4.0 gpd/sq.ft. application rate is required for a Cat III system and a 2.0 gpd/sq.ft. application rate would be required for a Cat II system. There is 3.5+ feet of MOA filter sand below the drainrock in this drainfield. After the effluent passes through 2+ feet of MOA filter sand, the effluent should meet Cat III effluent quality levels. This system has 3.5+ feet of MOA filter sand above the native (insitu) soils. The residence on this property has a total of 3 bedrooms, so 112.5 sq./ft. of absorption area is required for CAT III effluent (450 gpd / 4.0). The existing 2013 drainfield has 125 sq./ft. of absorption area. In short, the drainfield meets the Cat III sizing requirements. At this time, we request that your department approve a CAT II configuration be used at the referenced property, Upon your concurrence, we will have ARM Septic Service, LLC, either leave the Jandy valve actuator in the discharge position; or have them completely remove the actuator and leave the valve in the open position. We will also have them place a CAT II sticker on the control DanA , M.S. 3701 East Tudor Road, Suite 101 * Anchorage, Alaska 99507-1259 Phone: (907) 337-6179 * Fax: (907) 338-3246 * Website: www.garnessengineering.com Jody Maus From: ARM Septic Services LLC <armservicesak@outlook.com> Sent: Monday, April 29, 2019 11:23 AM To: Jody Maus Cc: Jeff Garness Subject: 8301 Robert Drive (CAT U Conversion) Jeff & Jody, Adam Christianson, the owner of the Quanics system located on 8301 Robert Drive (Rabbit Creek View & Heights; Block 8H, Lot 13A), gave ARM and Garness approval on 4/29/19 to convert the currently CAT III Quanics system to CAT II.

Box 196650, Anchorage, Ak 99519-6650 (907) 343-7904 Ref: Proposed Initial Septic System for Rabbit Creek Heights; Block 8H, Lot 13A To whom it may concern: The referenced property is currently vacant. The owner is proposing to build a 3 bedroom house that will be served by a private well and septic system. We are proposing to install a Quanics Aerocell treatment system on this property which includes the installation of a 1500 gallon S.T.E.P. tank and a trench type drainfield. Attached are a site plan and a design drawing showing the proposed septic system. Two test holes were excavated on the property. The drainfield will be designed around the 30 foot radius of test hole #2. Comments regarding the design are summarized as follows: 1. SOILS: See the attached logs which show the soil classifications, grotmdwater monitoring, and the percolation test results. 2. DRAINFIELD DESIGN: See attached design drawing for dralnfield specifications. 3. SURFACE WATERS: There are no surface water concerns. A curtain drain has been installed on the south end of the property. The proposed septic system is located below the curtain drain. 4. TOPOGRAPHY: As can be seen on the attached topography drawing there are no slope Concerns. 5. LOT LINE WAIVER REQUEST: The proposed drainfield location is located 1 foot from the east lot line. We request that your department issue a 1 foot lot line waiver. The owner of Lot 13A is also the owner of Lot 12A and both properties will serve for the single residence. In short, there is no drainfield on Lot 12A that may encroach on the proposed drainfield on Lot 13A. There is minimal risk associated with the granting of this waiver. 6. PROPOSED PRIMARY & RESERVE DRAINHELDS TO FOUNDATION DRAIN WAIVER REQUEST: The proposed primary & reserve drainfield locations are located within 3701 E. Tudor Road, Suite 101 * Anchorage, AK 99507-1259 Ph: (907) 337-6179 * Fax: (907) 338-3246 * Website: www.garnessengineering.com 25 feet from the proposed foundation which will likely require a foundation drain. We request that your department issue a 25 waiver from the proposed drainfields to the proposed foundation drain. We are proposing to inslall a Cat III Nitrogen removal system, based upon the high quality effluent we believe there is minimal risk associated with the granting of this waiver. We are unaware of any adverse impacts this installation would have on adjacent wells or septic systems. If you have any questions, please contact us at 337-6179. Thank you for your assistance.
