Pannone, Principal Registered Professional En§ineer E-mail: steve@panengak.corn Subject: DALE BRIGGS B1 L4 Septic System Install Permit Request Design Narrative 21April2016 This is a design narrative for a permit to install an initial septic system to be issued for this property. The proposed systems will serve a proposed six-bedroom (6) house. Currently the lot is developed. This lot is served by a Class "C" Well (classified as such by ADEC dated 16DEC15) and the surrounding lots are served by either private wells or public water service. The wells on the surrounding lots are over 100' from the septic system. Awe]lseparationwaiverfortheundocumentedexistingsepticsystemandtheproposed septic system to the existing Class "C" Well was granted by ADEC on 28DEC15 (ADEC Plan Tracking Number 15 WW-3S2). Both ADEC documents are attached. Soils. One test hole was performed in the vicinity of the proposed system by Pannone Engineering Services in August of 2015, and groundwater was monitored for at least seven days. Ground water was not observed to a depth of 15.0 below the surface in the test hole monitor tube in September of 2015. Based on the results of the percolation tests an application rate of 1.0 gallons/day/square feet was used for a conventional waste water system in the area of this test hole. 2. Soil Absorption System Design. a. See Sheet 2 of the design package. 3. Surface Water: There is no surface water within 100 feet of the proposed septic tank and drain field. Th(~ proposed drain field upgrade will maintain at least 100 feet from all surface water and drainage ditches. 4. Topography: The existing overall topography slopes up from the northwest to the southeast at approximately 5%-7% on the lot. There are no steep slopes within 50' of the proposed drain field. 5. Waiver Requests: A well separation waiver for the undocumented existing septic system and the proposed septic system to the existing Class 'C' Well was granted by ADEC on 28DEC15 (ADEC Plan Tracking Number :15 WW-352). A slope waiver is required as the system is approximately 25' horizontal feet from a slope over 25%. A shown on Sheet 2 of the design package the assumed infiltration line will not daylight 50' from the absorption field. 6. Drawing Markings: The Drawings are marked "For MoA Review Only".

Based on a review of the submitted information and the Kd.es in tiffs office, the public water system (PWS) is classified as a Class C PWS. SYSTEM CLASSIFICATION: CLASS C SERVICE & POPULATION INFORMATION USE Private Homes NUNfBER OF SERVICE CONNECTIONS 2 NUMBER OF DAYS PER YEAR OF OPERATION 365 RESIDENTS (PRIJSL~RY PLACE OF ABODE) 16 NON:I'RANSIENT (>6 MONTHS/YEAR) 0 TIC, kNSlENT (<6 MONTHS/MEAR) 0 The well is located on Dale Briggs B1 L4, and serves a two bedroom single farruly home and a slx bedroom duplex. Due to the limited population served by the well at Dale Briggs Bi L4, the system is classified as a Class C water system under 40 CFR 141.2 knd i8 ~O,C 80.1990. You are required to contact the deparnnent to update this information ~vhcn it changes. Changes to the number of setw-ice connections, population served, or number of days of operation may result in a change to the system classification and the associated plan review and maturating requirements. Class C Registration tn the plans provided it was noted that the well fails to meet the minimttm separation distance of 150 feet betxveen a dr~ztdng water source and wastewater disposal systems and the 100 feet between a community sewear line as outlined in 18 _&AC 80.020. Separation distance waivers for Class C systems are admin/stered by the ADEC DMsion of Water (DOW). If you have any questions please contact Bill Rieth, PE at (907)-269-7519. At this time, the Drinking Water Program is nor processing class C registrations. The completed forms wffi be filed for future reference and shared with other :a~gency programs that may regulate youx faciI/ty. Please see the attached memorandum dated September 23, 2015 for further information. The reqxiiremenrs of 18 AAC 80 remain in effect. This includes source construction standards, minimum sepsz'ation distance requirements, water qualit3, standards, treatment Mr. Dunham 2 December 16, 2015 requi~cements for certaSn systems and you are responsible for assuring compliance ,with these requirements. We recommend routine bacter/otogica& nitrate, arsenic, and chemical testing for public health protect/on, howe~,er, they are not required to be submitted to the ADEC Drinldng Water Program. Total Coliform It should be noted that in the pLans provided the wcl/tested positi~,e for total coliform and a subsequent test for fecal col/form came back negatixre. The well is located only 72 feet from the septic system and this could lead to the xvell having }5gh levels of fecal coliform. Total coliform is an indicator that ~'arious bacteri2, protozoa, and viruses that make people sick may be present in 5'our water. I would recommend testing the well water at least once a year to nmke sure that the we~l is free from coliforms although this is not req~fired to be submitted.

Box 100217 Anchorage, Alaska 99510-0217 Re: Eagle River-Dale Briggs, Block 1, Lot 4- Waivers from a Class C Public Water System Source well to Domestic Wastewater Treatment and Disposal Systems identified within the Class C Source Well's Protective Radius-ADEC Plan Tracking Number 15 WW-352 Dear Mr. Lawendowski, On December 17, 2015 the Department received finished Classifying the water system, and the waiver review was started based upon the engineer's reco~urnendations concerning health and safety issues. The questions concerning the cities distribution water line in the street has been investigated and a determination made. Although available for connection, it has not been required for this property to connect to the distribution system at present. (AWWU is the owner and controls this utility) The lot Based upon a site investigation the construction of a steel two part septic ta~k was to be installed in 1999 and does by your records appears to be in the proper planned site. It was found to be operational and is providing good service to the user. The onsite soil absorption system was to have been installed with a length of 75 feet this is confirmed by field measurements. Testing has shown that this unit is operating within the 900 gallons per day design values. The existing Class C source well is not plarmed to be altered, it was determined to be meeting the classification requirements. Thus per the engineer the source well is protective of public health concerns and based upon the engineers recommendations and the test results for Nitrate (2.12 rog/l), and the microbiologic negative results. The following waivers are established and are confirming the present site conditions and future modifications on the new systems field as follows: Based upon the engineers recommendation the existing septic tank for the two bedroom home is meeting the needs and is 58.2 feet from the source well. This has been a private system and testing has not indicated a health concern thus the I50 foot distance is reduced to the existing separation distance for the present conditions. The engineers recommendation of establishing the separation distance to be now equal to the existing two bedroom homes disposal field of 70.6 foot separation distance is similarly reduced to 150 feet as it is an existing condition that has not indicted per sampling a concern for public health. The new installation of a Duplex (six bedroom) on the lot requires a second field to be within 124.9 feet of the existing source well on the lot, it also is per the engineers recommendation reduced from the 150 foot distance to the requested distance as stated. Waivers as they were requested by the engineer are established. This is an older site with activities not expected to increase in use at the two bedroom home and with only a new demand made by the new Duplex (six bedroom) being altered. Should it be found that the site conditions endanger public health or are a public health concern, the waivers will be rescinded. This approval does not imply the granting of additional authorizations nor obligate any state, federal or local regulatory body to grant required authorizations. Any person who disagrees with this decision may request an adjudicatory hearing in accordance with 18 AAC 15.195- 18 AAC 15.340 or an informal review- by the Division Director in accordance with 18 AAC 15.185. informal review requests must be delivered to the Division Director, 410 Willoughby Avenue, Suite 303, P.O.
