P-antnone, Principal Registered Professional Engineer E-mail: stevePoanengak.com May 10, 2016 Subject: Contour Acres #1, Lot 3 Septic System Permit Request Design Narrative This is a design narrative for a permit to install a well and septic system to be issued for this property. The proposed system will serve a proposed four (4) bedroom house. Currently the lot is undeveloped..A conventional septic tank and drain field will be installed. The reserve septic area is shown. This lot and the surrounding lots are served by private wells. There are no wells within 100' of the proposed septic system, and there are no septics within 100' of the proposed well. 1. Soils. Two test holes were performed in the vicinity of this system by Pannone Engineering Services in May 2016, and groundwater was monitored for at least seven days. Ground water was not observed to a depth of 14.0' below the surface in the test hole monitor tube in May 2016. Bedrock was not encountered in the test hole. Based on the results of the percolation tests and overall soils appearance; an application rate of 1.2 gallons/day/square was used for a conventional wastewater system in the area of these test holes. 2. Soil Absorption System Design. a. See Sheet 1 of the design package. 3. Surface Water: There is no surface water within 100 feet of the proposed septic tank and drain field. The proposed drain field upgrade will maintain at least 100 feet from all surface water and drainage ditches. 4. Topography: The existing topography slopes from east to west at approximately 5% to 10% in the area of the drain field. There are no steep slopes within 50' of the proposed drain field. The proposed drain field will maintain 50' separation all steep slopes. 5. Drawing Markings: The Drawings are marked "For MoA Review Only". When written notification that the review is complete and that there are no further comments is received from MoA On -Site Department, the note will be removed and "Issued for Construction" drawings will be issued. The proposed installation will not affect the future development of this or the surrounding lots. Mailing: P.O.

STATEMENT OF INSPECTION BY ENGINEER As certified by my seal affixed hereto and as of the validation date shown below. I verify that my investigation, based on procedures outlined in the Certificate of On=Site Systegts Approval Guidelines for this application, shows that the on-site water supply and/or wastewater disposal system is (are) safe, functional and adequate for the number of bedrooms and type of structure indicated herein. I further verify that based on the information obtained from the Municipality of Anchorage riles and from my investigation and inspection, the on-site water supply and/or wastewater disposal system is(are) in compliance with all applicable Municipal and State codes, ordinances, and regulations in effect at the time of installation. In conducting an adequacy test, I attempt to provide a thorough, conscientious engineering analysis of the system in accordance with MoA COSA guidelines and regulations. The reported results describe 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 211 wells and septic systems depend on the local soil condition, ground water 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 this system. All systems eventually fail and satisfactory test results do not guarantee future performance of the system, nor do they guarantee that there are no hidden defects or encroachments. Therefore we cannot provide any warranty for future performance, nor can we estimate remaining life of the system. The content of this report is for the sole benefit of the owner listed above.

The Environmental Protection Agency (EPA) has established a maximum contaminant level (MCL) of 10.0 mg/L for public drinking water systems. While private wells are not subject to this regulation, EPA standards are based on existing health information and can therefore be used to gauge the relative quality of water from private wells.
