Box 196650 Anchorage, Alaska 99519-6650 Re: Lot 7 Shell No. #2 S/I) To Whom It May Concem: This is a request for a new septic and well permit for new construction by Spinell Homes. The pert was 40 minutes per inch the same as lot 6 to the south however water was observed at I4 feet. The soil log consisted of the same sandy silt SM as lot 6 for the complete depth. Water was observed only after 7 days at 14 feet. This could have been due the severe rain we had at the time of the test hole excavation. Due to this water table a "Bottomless Sand Filter" has been designed to remain above the water table and fit on the small space available. Due to the time restriction to get the building permit, additional test holes will be excavated after the foundation is done to verify the water table} which was not found on lot 6 directly to the south. If the water table can be revised this permit will be changed to a conventional system if possible with resubmittal. The peru test was found to be 40 minutes the same as lot 6. The lot slopes gently to the north at about 2 to 5 percent. The new sand filter will be constructed in the south west comer where the lot is very fiat. The lot is bordered by two streets and one driveway therefore this new system will not encroach any neighboring lots for future development.

Box 196650 Anchorage, Alaska 99519-6650 Re: Lot 7 Shell No. #2 S/D (Revised Permit SW030471) To Whom It May Concern: This is a request for a revised septic permit for Spinell Homes. A new test hole was excavated to a total depth of 17 feet. No water was observed as the previous test hole showed and the material consisted of silty sand SM then changed to clean sand at 10 feet, to the bottom half of the test hole. The peru rate in the silty sand was 16 minutes per inch. The original test hole had silty sand material and water at 14 feet, however after reviewing the site over the past year, the water must have come from the heavy rain which occurred during the test hole excavation. Various other holes have been excavated for water lines, foundation etc. with never any water observed. Even the well drilling, which has been completed, did not find water at 14 feet. The new system is a 7.5 feet effective, deep trench system, for a total length of 67 feet. The primary and secondary system have been shown on the plan, with 15 feet between trenches. The 1250 gallon tank has already been installed, see the plan. The well has also been installed under the old permit. The lot slopes gently to the north at about 2 to 5 percent. The new deep trench will be constructed in the area boarding the Well radius tO the north which is flat. The lot is bordered by two streets and one driveway therefore this new system will not encroach any neighboring lots for future development.

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. ` � Mailing address P (? Box 19665Q *:Anchorage, Alaska 99519 665p * www muni org ss 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.

The approved separation distance is 30.0 feet. Waiver is for water well located on Lot 7 to animal containment area on Lot 5. This waiver approval applies to the existing animal containment area to private well separation only. Any future upgrade to the on-site wastewater disposal system will require all separation distances be met or another approval from this department. If there are any further concerns or questions regarding this waiver, please call our office at 343-7904. Sincerely, Julie Makela, P.E.

The lot directly to the east has horses and corrals within the I00 foot Setback of the existing well. The following items are my rational for the granting of this waiver: 2, 3. 4. 5. The well is very deep 267 feet. The Animal Containment Area is located across the oiled road and down hill from this site. The water test has low nitrate level typical for the area, test sheet attached. The coliform and other bacteria are zero, test sheet attached. The soils around the well has been mounded up for maximum drainage. If you have any question please call me at 345-3377 Michael N. Anderson, P.E.
