The owner would like to replace it with a new septic system and upgrade the to a 4 bedroom system. We are proposing to install a new septic tank, and a new drain field. The old tank will be demolished per moa requirements. Our review of available documentation and field investigation show that this project will not adversely impact any nearby Wells, Wastewater disposal systems, replacement disposal sites, or drainage flowing onto and off of the subject property. The existing drain field is sized for 3 bedrooms and may be used as a 4 bedroom reserve site with the installation of an AWWTS system. There is also sufficient space for a new AWWTS drain field elsewhere on the lot. The existing trench should not be used for the 4 bedroom system and shouldn’t be tested for any COSAS. It does however serve as a good temporary backup should the new system fail, and as a suitable reserve site if an AWWTS system is used, or if it is extended. A waiver request for a drainfield to steep slope waiver has been provided as a separate document. Included with this letter is a permit application and design package, including plans, and calculations. A test hole was excavated, however a deeper test hole will be excavated to 16’ deep during construction to verify soil conditions and the groundwater table. Thank you for your time in reviewing this permit request. Please do not hesitate to contact me at 907-854- 5558 or by email cgbalzarini@gmail.com with any questions or concerns.

The proposed drain field will be a minimum distance of 12.7’ from the top of the steep slope. W e believe the following points mitigate the drainfield’s proximity to the slope and greatly reduce chances for effluent to travel horizontally and break the ground surface: • The soils are free draining which will help effluent to disperse vertically downward with less chance for horizontal migration. A copy of the soils log has been attached. • The existing slope is stabilized by vegetation reducing risk for erosion. • The attached cross sections show the existing slopes relative to the drain field. In most cases, a theoretical 25% placed 2.5’ above the invert of the distribution pipe would daylight over 35’ from the edge of the system. At worst, the 25% line daylights 26.5’ from the edge of the system. At no point, does a 46% slope line placed at the same location, daylight below the system. • Since the 46% slope line does not daylight, that means the system should behave similar to a system installed on a slope less than 46%. A relatively minimal amount of fill could be placed downslope of the system to prevent the 25% line from daylighting within 35’ of the slope. It’s likely that placement of fill could ultimately damage the existing native vegetation which adversely impact the slope. For these reasons, we believe the drainfield to steep slope waiver is justified. Thank you for your time in reviewing this request. Please do not hesitate to contact me at 907-854-5558 or by email cgbalzarini@gmail.com with any questions or concerns.

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. 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. �1VIrMyng��c�es�s�ox* �An�c or�ge� ask nCr 1 60 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. Well Water Advisory Certificate of On -Site Systems Approval #OSC191314 Subdivision: Chugach Park Est., Block: 1, Lot: 22 This well's productivity was determined to be .83 gallons per minute. The minimum well productivity required under (AMC 15.55) for a 4 -bedroom residence is .41 gallons per minute or 150 gallons per day per bedroom. Although the subject well currently exceeds this minimum requirement, the production capacity can fluctuate.
