Box 196650 Anchorage, Alaska 99519-6650 Reft Well and Septic Design for Lot 2, Ptarmigan Subdivision To whom it may concern: The existing 3 bedroom house is served by a class "C" well located on Lot 1, Ptarmigan View and a private septic system. The existing septic system consists of a documented log crib and an undocumented trench. The septic system on the lot is in a state of failure and needs to be upgraded. A test hole was excavated on the property. The proposed septic system will be designed around the 30 foot radius of test hole #1. We are proposing that a 1000 gallon septic tank and a trench type drainfield be installed. Comments regarding the proposed design are summarized as follows: 1. SOILS: Attached is a soil log wtfich shows the soil classifications, groundwater monitoring, and the percolation test results. The soils below the organic layers are a SP material to a depth of 16.5 feet (bottom of test holes). No groundwater was encountered during the excavation of the test holes. A percolation test was performed between the depth of 7.0 feet and 7.5 feet which had a percolation rate of<l minute/inch. It is our opinion that the insitu softs will serve as a sand filter. 2. TRENCH DESIGN: a. Percolation Rate: <1 minutes/inch b. Allowable Application Rate: 1.2 gallons/day/ft2. We will use 1.0 e. Number of Bedrooms: 3 d. Design Flow: 450 gallons per day e. Minimum Absorption Area: 450 ft2 f. Total Depth: 10.5 feet (max.) g. Effective Depth: 6 feet h. Width: 2.5 feet i. Minimum Length: 38 feet long j Effeative absorption area = 456 ft2 6901 Debarr Road, Suite 2B N Anchorage, AK 99504 Ph: (907) 337-6179 - Fax: (907) 338-3246 - akwwc, com 3. SURFACE WATERS: There are no surface waters within 100 feet of the proposed upgrade. 4. TOPOGRAPHY: There is a slight hill that rans parallel to the proposed trench. The trench is to be installed parallel to this slope contour. 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, or 244-9612. Thank you for your assistance.

Eaton, P.E. 11835 Spyglass Circle Anchorage, AK 99515 SUBJECT: Lot 1 & 2, Ptarmigan View Estates Subdivision - 3051 E. 112th Avenue; Class "C" Public Water System Letter of Compliance, AWPSA Project No. 9836-0201-WJ-0012. Dear Mr. Eaton: This letter is in response to t~e information received in this office September 3, 1997, requesting a letter of compliance for the above Class "C" Public Water System serving a single family residential dwelling. The Department has completed a review of the monitoring status of this water system and found it to be in compliance for both coliform bacteria and nitrate. Since this drinking water system has been previously approved, and because it serves less than 13 bedrooms or 25 residents, this water system is Viewed as a Class "C" Public Water System. Verification that the water supply has been recently tested will be required to maintain compliance with State Drinking Water Regulations. Recently collected water sample analysis (7~28~97) were satisfactory for both total coliform bacteria and nitrate and satisfy this concern. Therefore, for the concerns of this Department, this system is in compliance with State of Alaska Drinking Water R~§ulations (18 AAC 80). Attached is a "Public Health Authority Approval for On-site Drinking Water and Sewer Systems" cert ficate verifying th's system's status as an approved water system that is in compliance with 18 AAC 80. Any future modifications to this system will require prior review and approval by this office. Please note that this letter does not imply any certification or status of the existing on-site wastewater disposal system serving this property. Thank you for your cooperation with this Department, if there are any questions regarding the above, please do not hesitate to call. Sincerely, ~ Michael Lu Environmental Engineer MLU/cf Attachments cc: Jim Cross, MONDHHS
