Health & Human I On-Site Services Section P.O. Box 196650 Anchorage, Alaska 99519-6650 ReP REVISED DESIGN for Sewer Upgrade at T15N, RIW, Sec 16, NWl/4, NWl/4, SWl/4, SWI/4 To whom it may concern: A permit was issued by your department for the subject upgrade on 9/2/97. The original design called for the installation of 2 shallow trenches, with sand filters. This type of design was required due to the fact that, in the only test hole dug, the soil profile was primarily clean gravel that perked faster than 1 minute/inch. During the installation of the septic tank it was discovered that the soil, to a depth of approximately 10 feet, was clean sand. Consequently, a test hole was dug (see location on revised plan) to 14 feet, and again, clean sand was encountered. In short, it appears that the soil to the east of the original test hole is primarily sand. Given the presence of the sand, we are proposing to modi~ the trench design. The specifics regarding the design are summarized as follows: 2. REVISED TRENCH DESIGN: a. Percolation Rate: < 1 minute/inch b. Allowable Application: 1.2 gallon/day/ft2 c. Number of Bedrooms: 4 d. Design Flow: 600 gallons per day e. Minimum Absorption Area: 500 fi2 £ Effective Depth: 4 feet g. Reduction Factor = N/A h. Width: 5 feet minimum i Minimum Length: 50 feet. j Effective absorption area = 500 ft2 3. SURFACE WATERS: There are no surface waters within 100 feet of the proposed septic upgrade. 4. TOPOGRAPHY: A copy of the topography map for the lot was submitted with the original design. The slopes downhill and within 50 feet of the proposed trenches, are approximately 25% There may be some localized slopes over 25%, however, they should not be a concern since the soil porosity dictates that the wastewater will move downward very rapidly, with very little lateral migration. In short, them does not appear to be any slope concerns. I am unaware of any adverse impacts this installation would have on adjacent wells or septic systems. If you have any questions, please contact me at 337~6179, 244-9612, or on my digital pager at 1-800-481-1162. Thank you for your assistance. Sincerely,_ Jeffr l/ .[q arness, P.E., M.S.
