Date // GAG Engineer's Comments: In conducting this evaluation, GEG, LtD. attempted to provide a thorough, conscientious engineering analysis of the system in accordance with ADEC and MOA DSD Guidelines 8 Regulations. The reported results described the performance of the system under the conditions encountered at the time of the test, and separation distances measured to readily Identifiable features. The operational life of all wells and septic systems depend on the local soils condition, groundwater levels that may fluctuate during the year, and the water usage of the family being served by the system. These conditions are outside the control of the evaluator of the system. Satisfactory test results do not guarantee future performance of the system, nor do they guarantee that there are no hidden defects or encroachments. GEG, LTD. can therefore not provide any warranty or future estimate of how long the system will continue to moot the operational requirements of the ADEC or MOA DSD.

The approved separation distance is 90 foot horizontal separation from well on Mountain Park S/D #2 Block 3 Lot 3 to septic crib on lot 2. This waiver approval also applies for a 0 foot lot line from septic crib to west property line Any future upgrade to the on-site wastewater disposal system will require all separation distances be met or another approval from this department. If there are any further concerns or questions regarding this waiver, please call our office at 343-7904.

Engineer: Jeffrey Gamess. P.E. IIA060314 Septic Crib Data The Crib was installed in 1972. This crib has encroached the well for more than 20 years. The bottom crib elevation was assumed to be 10 feet and was most likely installed in a sandy gravel layer. Well Data The well was installed after the Crib on Lot 3. The well is approximately 225 feet deep. There are detectable nitrates in the surrounding area. The water samples for Lot 3 are with -in Municipal Standards. According to Garness Engineering Nitrates are elevated in the area and are not directly related to the 90 foot encroachment.

GARNESS ENGINEERING GROUP, Ltd. CONSULTANTS & GENERAL CONTRACTORS June 29, 2006 Municipality of Anchorage Department of Health & human Services Division of Environmental Services On -Site Services Section P.O. Box 196650 Anchorage, Alaska 99519-6650 Ref: Waiver Request and COSA for Mountain Park Subdivision ti2; Lot 3, Block 2. The existing 3 bedroom house is served by a private well and septic system. On 4/21/06 a site visit was done in order to obtain a COSA. During the site visit the separation distance was measured from the crib pipe to the well on Lot 3, Block 3, and was found to be 104 feet. The exact location of the perimeter of the crib is unknown. Based upon conversations with your department a waiver is required. We request you grant a 90 feet separation distance waiver from the crib on the referenced property to the well on Lot 3, Block 3; The septic system on the referenced property was installed on 9/21/1972 and the well and Lot 3, Block 3, was drilled on 8/4/1975; therefore the owner of Lot 3, Block 2, is not responsible for the waiver fee. The following items are justification for the waivers: • The ground slopes from west to east; however there is a ditch alongside the road, so that if the septic system was to overflow, it appears that the effluent would not travel toward the well head. • The location of the septic system is in a very visible area so that if any effluent was to surface, it would be noticed and the problem corrected. The other path of contamination is subsurface migration of wastewater. As can be seen on the attached well logs, the static water levels in rearby wells ranges from 40-270 feet, and bedrock ranges from 30- 290 feet. There are several layers of silty sand, gravel and clay that have served to inhibit the migration of untreated wastewater into the aquifer Recent water sample results indicated nitrate levels to be 5.70 mg/L and coliform bacteria results to be undetected. Based upon our experience, nitrate levels are elevated throughout the area and are not directely related to this encroachment. This encroachment has been in existence since 1975. Based upon the aforementioned facts, it appears that there is minimal risk associated with the 90 feet separation distance waiver. We also request a 0' lot line waiver from the existing seepage pit to the west lot line. We are unaware of any adverse impacts that are associated with the granting of this waiver. If you have anykestions, please contact us at 337-6179. Thank you for your assistance. .E., M.S. 3701 E.
