The following information also supplement~ our l~tter of June 4, 1987, request for waiver. The well site proposed on the original plot plan required the excavator to cut a bench across a moderataly steep slope in order to provide a site for the w~ll driller to set up his rigging. At the time the bench was excavated there was still some frost in the ground, however, by the time the w~ll driller was ready to s~t up his rig, breakup had almost ended. The site proposed for the well to be drilled was near a lower edge of the w~l pad and in the opinion of the well driller co~tituted an unsafe condition, therefore, it became necessary for him to shift the well location to the uphill side of the pad and closer to the proposed septic system. When the excavator i~talled the septic tank he used the existing dwelling as his reference since it was extremely difficult to measure through the house and to adjust for slope conditions. In doing so he did not adjust for the moving of the w~ll from the outside of the pad to the inside of the pad. He may v~ry we~ have not been aware that the well site had been moved. It was not until after the well and septic tank were installed that we realized that the horizontal separation distance had been decreased and I am not sure that it would have been pra~cal to attempt to reco~truet a w~ll pad closer to the lake prior to drilling the w~ll. As we stated in our letter of June 4, it is our opinion that the horizontal separation distances prescribed by Municipal Ordinance are not required in this case. It should also be noted that with the septic problems that have long been associated with property on Fire Lake, public sewer is inevitable. f~AS/ss SRB 196X EAGLE RIVER. ALASKA 99577 ROBERTA.

In August/September, 1985, a p~rmit was issued for a w~l and septic and a land use permit was issued for construction of a three bedroom residence on th~s property. The house has been constructed and is nearing completion. The owner, Mr. Brandenburger, has contacted us to design and have installed an on-site wastewater disposal system. Since the originalsoil test did not include water monitoring and the original permit was not used we have re-excavated a test hole and are currently monitoring for ground water. We wi~ be seeking a permit for the on-site wastewater d~posal system as soon as ground water monitoring has been completed. Due to the site of the proposed well, it is, however, necessary that the well driller g~tinto the site and drill the w~l before the ground thaws, therefore, we are requesting the w~ll permit in advance of the on-site s~wer p~rmit. It should be recognized that this lot will not provide for the reserved areas specified in the current Municipal Ordinance, however, it is our understanding that the Municipal sewer will be provided for all the residents around Fire Lake in the near future, therefore, the current on-site wastewat~r disposal system should be adequate until public sewer is available. In the event that a failare should occur to the proposed on-site system prior to public sewer b~ing available a holding tank will be used as an alternative. There are several properties on Fire Lake that currently use holding tanks. A committment to the dev~opment of this property was made with the issuance of a land use permit in September, 1985. The fact that development was not completed prior to the carrentMuni~ipal Ordinance should not preclude the completion of this project.

Box 196650 Anchorage, Alaska 99519-6650 REFERENCE: Lot 14; Block 2; Lake Ridge Terrace Subdivision; This letter is to add additional comment to the attached Health Authority Approval Request. As can be seen from the attached data the nitrate levels within the drinking water we~ are unusually high at 8.6 mg/1. This is especially concerning when the well and septic tank are operating under a separation distance waiver. However, since wastewater does not seep directly into the ground at the location of the septic tank (especially one as new as this) we are assuming a greater separation distance between the septic tank and the well wou~d not resolve the apparent problem. It seems the well is being influenced from the septic leachfield. A~tually, ~ is probable the well is being influenced by a pre-existing neighbor's septic system since the nitrate levels were 2.6 mg/1 within the well prior to the septic system on the referenced property being placed into use. At this time the nitrate levels are within allowable limits, therefore, we are requesting a new Health Authority Approval. Naturally we recommend the usual recommendation for p~riodic water sampling be placed on the Certificate. Sincerely, ROGER J. SHAFER, ~P.E.
