This department will verify that upgrading is completed no later than June 15, 1993. Water monitoring will be required on all test holes through May, 1993. The proposed well on Lot 2 must be relocated slightly to accommodate additional reserve area needed for this lot.

Proposed Narnia Subdivision Dear Susan, At the request of the property owner and per our telephone conversation on I/7/93, we visited the referenced property to further investigat~ the existing s~ptic system. The septic system is apparently undocumented, however, the current owner says the previous owner claims the system consists of a "1000 gallon septic tank with a leachfield trench". Inspection of the property found 3 existing septic pipes. The standpipe closest to th~ house appears to be a septic tank cleanout. Approximately 1100 gallons of wastewater was pumped from the tank. The second standpip~ is a 4 inch PVC cleanout in the s~w~r line leading from th~ septic tank to the leaehfield. The third pipe within the system is apparently a l~achfield monitoring tube. Inspection of this pip~ found a liquid l~vel approximately 2 ft. from the ground surface. Approximately 200 gallons of ~ffluent was pumped from this pipe. Th~ s~ptic system s~rving the property apparently consists of a septic tank/leachfield type system. Test hol~s excavated on the property in October, 1992 suggested no groundwater encroachment existed at that tim~. However, an encroachment may exist on the bedrock. Due to the unusually high liquid level within the leachfield monitoring tub~, I susp¢cl the system is in a state of failure with little absorption capacity. However, inspection of the area adjacent to the leachfield did not reveal any surfacing effluent or other obvious signs of an eminent health hazard. It should also b~ noted that in the event the septic system do~s overflow, the septic tank cleanout is accessible for periodic pumping as necessary to minimize health hazards until the septic system is upgraded. 17034 EAGLE RIVER LOOP, SUITE 204, EAGLE RIVER, ALASKA 99577 Pag~ ~wo SW~, SE~, NW~, SW~, S~ction 30, T15N, RIW, S.M.
