Bragaw Street P. O. Box 196650 Anchorage, Alaska 99519 Subject: Nina, Lot 2 Septic System Upgrade Permit Request Ladies and Gentlemen: I am writing to request a permit to install an upgrade septic system be issued for this property. The proposed systems will serve a proposed three (3) bedroom house. Currently the lot is developed. The existing structure will be removed and a new three bedroom house will be constructed. The existing undocumented septic system will be abandoned per code and a new system will be installed. The proposed system will utilize a 1000g septic tank with a wide trench type drain field. The surrounding lots are served by private wells. There are no wells on surrounding lots within 100 feet of this system. 1. Soils. One test hole was performed by Pannone Engineering Services in March of 2014 and groundwater was monitored for seven days. Ground water was not encountered in the test hole after the seven day monitoring period. It is my opinion, based on the results of the percolation testsand overall soils appearance; an application rate of 1.0 gallons/day/square feet should be used for a c~ventional wastewater system with a 2' sand filter. 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 ta~k 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 the west to east at approxima~y 2% to 4% in the area of the proposed drain field. There are no steep slopes in the vicinity of the drainleld, Mailing: P.O.

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 the surrounding or existing lots. There are no surrounding wells within 100 feet of the proposed septic location.

Name of Firm Areterra Consulting Phone (907)-696-6111 Engineer's Printed Name Kenneth Duffus Date d 1z,6 - Engineer's Comments: This investigation was completed in compliance with ADEC and MOA regulations. The assessment of the condition of the well and septic applies only to the conditions as of the day tested. The flow and absorption rates may change due to subsurface conditions that may not be observed from the surface, changes inland use, local soil characteristics, groundwater levels that may fluctuate during the year and the water usage of the family being served by the system. The operational life of all well and septic systems are subject to these various and dynamic characteristics and are outside the control of the evaluator of the well and septic system. Therefore, AreTerra can not give any estimate of how long a system will function satisfactory for current or future occupants or can AreTerra guarantee that no unseen encroachments, deficiencies or discrepancies exist.

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. Since nitrates are known to slowly increase, we recommend you monitor the water quality. Please see the attached "Nitrate Fact Sheet" for important information regarding nitrate. This advisory must be attached to all copies of the subject Certificate of On -Site Systems Approval. Nitrate Fact Sheet From Northern Testing Laboratories, Inc. Nitrate is a negatively charged compound of nitrogen and oxygen, which is very soluble in water. Nitrate is not readily filtered or otherwise removed in the soil and can pass rapidly into ground water wells. SOURCE: Nitrate is a major component of fertilizer and wastewater. Often the nitrate is in the form of ammonia or protein first, which through contact with oxygen and certain bacteria, converts to the oxidized form known as nitrate. Sources of nitrate from wastewater include urea, ammonia cleaners, food solids, and bacterial cells. It may also result from the breakdown of organic matter buried in the soil. TOXICITY: Nitrate is generally not toxic to adults or children over the age of two or three years, but is associated with a potentially fatal infant disease called methemoglobinemia. In the digestive system of young children, nitrate converts to nitrite, which can pass through the intestinal wall into the blood stream. There it combines with the hemoglobin and interferes with the ability of the blood to carry oxygen. For this reason, methemoglobinemia is referred to as "blue baby" disease. The EPA limits the concentration of nitrate in public drinking water supplies to 10 mg/L. The standard has been lowered from a previous level of 45 mg/L set by the US Public Health Service and the World Health Organization. TREATMENT: due to its solubility in water and negative ionic charge, filtration and other common home water treatment systems such as softening or iron filtration does not readily remove nitrate. The best method for limiting nitrate in well water is source control. This can include avoiding overdosing of fertilizer near the well and maintaining good separation distances between septic tank leach fields and the well. A special anion exchange filter that contains a media with a strong affinity for negatively charged ions in water, or by a reverse osmosis treatment system or distillation can remove nitrate. TESTING: Nitrate analysis is usually done by one of the several "wet chemical" methods using a spectrophotometer to read the final color endpoint. Specific ion electrodes also can be used to detect the activity of nitrate in water. This laboratory uses several different wet chemical methods approved under the public water supply laboratory certification program. They also have test kits available, which the laboratory uses to perform an inexpensive "screening test", and with which the homeowner can monitor the change in nitrate levels from their well. They recommend comparing the test kit results against a certified analysis from the lab occasionally to verify the accuracy of the kit. We recommend using a specially prepared bottle that has been rinsed in hydrochloric acid for collecting samples.
