According to our con- versation, DEC would grant a waiver of the 150 foot limit between the well and the septic system area as shown on our site plan if the drainfield could be located a minimum distance of 20 feet from the edge of the bluff. This would reduce the septic system area to 22' × 65' which is still adequate area to install the needed facilities. The Municipality of Anchorage requires the bottom of the trench to be a minimum distance aw~v from any sloping hill equal to the depth of the drain- field at the toe of the slope. This requirement will be exceeded with DEC additional condition. If there are any further questions, please contact our office. Sincerely, P.O. BOX 1302 EAGLE RIVER,. AK 99S] Re: Request of Waiver from l)epartmen['of"Environmental~ Dear Mrs. Splawn: - '.-' · · Prior to'submitting a formal proposal to provid~ on-site developmen~:~ posed three bedroom duplex we suggest you request a waive~' of the distance on a Class C well to a distahce of 100. feet. With this that the proposed housing unit;~ could be constructed on the lot and better septic system design. Our reasons are as followe~ 1.' If the septic system is located on top of the bluff, it wou potential surface run-off infiltrating the drainfield if the d~ was located in the flat area. 2. We suspect a high groundwater table in the flat area. 3. Excavation over the bluff could cause"future erosion. 4. Based on the soils percolation test performed by Mr. Oystei: 1980, the percolation rate is 30 min/in'. This.~: would require feet of absorption area for the three bedroom structure. The the test hole was 15 feet and therefore the drainfield would be mately 72 feet long. With the waiver~ there would be adequa~ room. a replacement drainfield. 5. With the relatively high percolation rate, this reduces th~ potential contamination of the existing wells from the proposed, s~ sys tern. ' Enclosed are the existing soils log and a site. drawing of your 10t. whii: the existing and proposed facilities of which DEC will request pri6f the waiver.
