We are therefore requesting a permit be issued for the upgrade of the septic system to accommodate the four-bedroom home on the lot. The attached Site Plan and backup documentation identify the location and configuration of the existing and proposed septic system. The existing Septic Tank will be decommissioned in accordance with Municipal Code. It will be replaced with a new 1,000 Gallon Septic Tank placed outside the 100' well radius on the lot. The existing absorption pit will be abandoned in place. Also identified on the plans are the locations of the existing well on this and adjacent lots and adjacent septic systems. The majority of the surrounding lots are served by Municipal sewer and water. The lot to the east has a Class C Well and a waiver has been issued allowing the new absorption trench to be 135' from the well. Protective radii are shown on the plans to the adjacent wells. Drainage arrows are shown indicating the current drainage patterns. The drainage patterns will be maintained after construction. The test hole recently placed on the lot indicated clean sand with some silt (SM/SP). The percolation rate was determined to be 4 minutes per inch. We have designed the system with an application rate of 1.2 gallons per day per square foot. We are proposing to place a 53' long x 5' wide trench with a 2' effective depth. The total depth of the system will be 6.5'. The test hole was placed to a depth of 14' and has remained dry since construction. The ground surface on the lot slopes slightly to the west in the area of the absorption Lot 69A, T13N, R3W, Section 33 September 16, 2010 Page Two trench. The trench will be placed parallel to the contours of the ground as much as possible and in conformance with design criteria. A minimum of 100' will be maintained between all components of the septic system and the proposed well and from any surface water in the area. If the system is constructed in accordance with our design the following statements apply: The system, if constructed as designed, will have no adverse impact on the wells in the area or those to be constructed in the future. The system, if constructed as designed, will have no adverse impact on existing septic systems in the area or those to be constructed in the future. The system, if constructed as designed, will have no adverse impact on reserve space, either surface or subsurface, on any lots located in the area. The system, if constructed as designed, will have no adverse impact on drainage patterns in the area. The current drainage pattern will be maintained. Sincerely, Michael E. Anderson, P.E.

The ne~ consists of a five wide trench on-site soft absorption system for the was system and finds it can be granted based on the following. The engineer has recommended reducing the separation distance from source well on Lot 69B from 150 feet to 135 feet to the onsite soft absorption system on Lot 69A. Samples taken show nitrates were not detected (sa~npled 09/07/2010). The source well log has lower layers of silts and clays (1¢2 foot depth), with coarse sand and gravel in the first 67 feet. ~ell to a 'system ~ewater The new 1000 gallon septic tank will have more than 150 feet of separation distance and will not require a waiver per the present design for a 3 be, lroom home used in this review. The Departm.ent bas reviewed the engineering plans submitted for the onstte wastewater disposal and treatment system and the waiver to 135 feet t~ the disposal field per the Wastewater Regulations 18 AAC 72.015 is based lupon the Information provided and 'the engineer's recommendation. / If the wastewater disposal' system fails or contamination can be traced )ack to the system, the waiver will be invalid.
