Alaska Water & Wastewater 6901 Debarr Road, Suite 2B Anchorage, Alaska 99504 Lots 3, 4, & 5, Block 7, Sand Lake Subdivision # 2-Interim Approval to Operate an AdvanTex Treatment System and an On-site Deep Trench Type Soil Absorption System with Waivers, ADEC Project # 3132 Dear Mr. Gamess: The Department has received on January 9, 2004, your ietter which includes a copy of the maintenance agreement for the AdvanTex Treatment system serving a six bedroom duplex on Lot 4. The system consists of a new 2,500 gallon two compartment Septic Tank Effluent Pumping system with two AdvanTex AX 20 pods, and a 15 foot Ionb, ~ ~5 foot effective depth deep trench system. Although the application rate is within the limits set for the designed advanced treatment system, verification in the field by determining if the application rate can be sustained will be required to assure the design is meeting the field conditions. After one year's operation an inspection report will be required to confirm the performance of the on lot system. Waivers The existing waivers which have been granted and are as f~ll,,, .... · The separation distance between the Class C public water well located on Lot 3, Block 7, Sand Lake Subdivision # 2 and the AdvanTex treatment system on Lot 4 of the same block, planned to serve the duplex, has been waived from 150 feet to 100 feet. · The separation distance between the proposed private water well located m: Lot 5, Block 7, Sand Lake Subdivision # 2 and t;¢ ~dvanTex treatment system on lot 4 of the same block, both serving the duplex, has been waived from 100 feet to 85 feet. · The separation distance between the proposed private water well located on Lot 5, Block 7, Sand Lake Subdivision # 2 and the deep trench type soil absorption system on Lot 4 of this same block, and waived from 100 feet to 90 feet. The distances noted in the waivers are from your submittal. It appears that these distances are from the nearest edge of the wastewater disposal system component to the nearest edge of the noted wells. If contamination can be traced back to the system, the waivers will be invalid. Wastewater System From the information submitted, it appears that the wastewater disposal system was constructed in accordance with State Wastewater Disposal Regulations and in accordance with the previously authorized waivers. Therefore, in accordance with State Wastewater Disposal Regulations (18 AAC 72.225), interim approval is extended to allow the operation of the system for one year. The signed construction approval portion of the Construction and Operation Certificate, constituting this approval, is enclosed with a note stating that the maintenance agreement is on file. ~:. ~fi~,a.[ 91~tm.nal approval, documentation on how the~.~d~anTex umt ha~ been ~ ~.~ ~ .~1:~ ~:~ y~a~...r j:~oBe, r~ and the in place men/toting for Total ~aspended ~goi'ffi~ [ .t~emie~ Oxygen Demand, Nitrate-N, Total Kjeldahl Nitrogen; and FecaI Coliform after one~ y~ar of operatioli. _) Any future expansion of the subject project will require additional approval from this office.
