Construction shall be in accordance with the approved site plan and design drawings, Municipal permit with any special provisions or conditions, and all applicable State and Municipal Wastewater Disposal Regulations. The contractor shall be responsible for obtaining any necessary underground utility locates. Unless specifically agreed otherwise, the property owner shall be responsible for final grading areas subsequently depressed from soil settling. Contractors installing wastewater disposal systems must be certified by the Municipal Health Department for system installations. Owners installing their own systems must also receive prior approval from the Municipal Health Department. SEPTIC TANK INSTALLATION: A septic tank is to be constructed by a certified septic tank manufacturer. Construction shall include two 4" cleanouts for pumping access. The septic tank shall be sufficiently bedded to prevent settling or shifting of the tank. Ail standpipes on the septic tank shall extend a minimum of 12 inches above final grade. 17034 NORTH EAGLE RIVER LOOP · SUITE 204 · EAGLE RIVER, ALASKA 99577 Page Two Lot 4A, Block 8, Kasilof Hills S/D August 18, 1995 Septic tanks installed with less than 4 ft. of cover shall be insulated. A foundation cleanout shall be installed one to four feet from the building foundation. In the line between the tank and the leachfield there shall be two adjacent cleanouts (unless an effluent pumping system exists within the septic tank). These cleanouts shall be located on undisturbed soil not more than 10 ft. from 'the tank. The first cleanout, in line, shall be to clean toward the leachfield. The second cleanout shall be to clean toward the septic tank. Final grading over the septic tank shall be such that a positive slope exists away from the septic tank. ABSORPTION TRENCH/DRAINFIELD INSTALLATION: Excavate the proposed trench to the dimensions shown on the design. The bottom of the excavation shall be within 2 inches of level. If the sidewalls of the excavation become smeared, they must be raked or scratched (ruffed-up) before grave]. (sewer rock) placement. Once the gravel is installed, the distribution pipe is to be installed level with the perforations faced downward° Gravel is then to be placed over the distribution pipe to provide a minimum of 2 inches of cover over the pipe. A silt barrier must be installed between the final gravel layer and the native soil backfill. Ensure the silt barrier covers the entire gravel surface before placing backfill. Monitor tubes shall be of four (4) inch diameter, installed approximately in the locations shown on the design, and extend a minimum of 12 inches above fina]. grade. The portion of the monitorinq tube extending through the gravel shall be perforated f~'om the bottom of the trench to the invert of the distribution pipe. This is equivalent to the effective depth of the gravel as noted on the design. Page Three Lot 4A, Block 8~ Kasilof Hills S/D August 18, 1995 Backfill over the final gravel layer must not be less than twenty-four (24) inches. Insulation must be installed when the backfill depth is less than thirty-six (36) inches. The finish grade over the trench must be mounded to prevent the formation of a depression after settling. MINIMUM MATERIAL SPECIFICATIONS: Any septic tank proposed for installation must be constructed by a Municipally approved septic 'tank manufacturer. The following pipe materials are approved for use in septic system installations in the Municipality of Anchorage: Type of Pipe Perforated Solid Cast Iron ASTM D3034 (PVC) ASTM F810 (HDPE) ASTM D2662 (ABS) Yes Yes Yes Yes Yes No Yes Yes Use of a type of pipe other than listed above must be approved by the inspecting engineer. Insulation shall be at least 2" thick extruded direct burial polystyrene (Dow Chemical Company Styrofoam HI or equal). Septic tank inlets and outlets shall be fitted with watertight couplings (Caulder, Fernco, or equal). A permeable nontoxic silt barrier (Typar 3401, Mirafi 140N, or equal) must be installed between the final leachfield gravel layer and the native soil backfill. Ail leachfield gravel (sewer rock) shall be 0.5"-2.5" screened gravel with less than 3% passing the ~200 sieve. When sand is being used as a filter material, its gradation specifications must conform to current M.O.A. or D.E.C. requirements. Page Four Lot 4A, Block 8, Kasilof Hills S/D August 18, 1995 INSPECTIONS: Typically there will be a minimum of three (3) inspections required during the installation of the wastewater disposal system. These inspections will occur as follows: The first inspection must be conducted after the excavation of ditches, pits, trenches, or beds and before the installation of any gravel. A septic tank may be set in place, but may not be backfilled before this inspection. The second inspection must be conducted after the placement of the silt barrier, gravel, distribution lines, standpipes, cleanouts, and insulation, but before the placement of any other backfill. The final inspection is to occur upon final grading of the property. Often there will be more than these 3 inspections required. Especially with the installation of multiple trenches, sand filters, pressurized distribution systems, etco Thus, the inspecting engineer is 'to be contacted at least 24 hours prior to the start of construction. If necessary, a pre-construction meeting will take place on-site. The inspecting engineer will not coordinate, direct or control in any way the contractors activities. The owner shall contract with the contractor to perform the work outlined in these specifications and plans and in accordance with the attached M.0.A. permit. There will be no contractual arrangement existing between the contractor and S & S Engineering. S & S Engineering shall be the owner's representative and will inspect the work as stated above to document the contractors activities. Final acceptance of the contractors work rests with the owner and the M.O.A. Page Five Lot 4A, Block 8, Kasilof Hills S/D August 18, 1995 S & S Engineering shall have no liability to the owner or to others for acts or omissions of the contractor or any other persons performing work on this project or the failure of the contractor to carry out the work in accordance with these construction documents. S & S Engineering's inspecting engineer will not be responsible for the construction means, methods, techniques, sequence, procedures or the safety precautions incident to this project.

Name of Firm Phone Engineer’s Printed Name Date C&M ENGINEERING SERVICES Ph: 907-854-5558 Municipality of Anchorage Onsite Water & Wastewater Program 4700 Elmore Rd Anchorage, Ak 99507 RE: COSA for Kasilof Hills Lot 4 Block 8 Dear Reviewer, The septic system on the subject property was installed in 1995, including a 1250 gallon steel septic tank. The homeowner indicated that the system was very lightly used for the first 8-years after it was installed. When we tested the system, the level in the tank measured 51-inches, which is the nominal tank level. Typically with older leaking tanks, we find the level to be below 51-inches. Corrosion is generally known to require an electrolyte and oxygen to occur. Wastewater has both and is corrosive. There is localized wetting and drying along the waterline of the tank, as the tank is used and the levels fluctuate up and down slightly. This is likely why we see can more corrosion holes right around the tank waterline than at other areas of the tank. Sewage also emits gasses which corrode the steel. The soil type, moisture in the soil, and quality of the coating will also play a factor. A system that is lightly used for a long period of time is going to have a lower concentration of corrosive elements and oxygen over that period of time which should result in less corrosion. We acknowledge that it is impossible to determine the actual impacts of usage on the integrity of the tank, however the long period of minimal use likely has some impact and believe the condition of the tank is going to be similar to that of a tank which has been in service for 25-30 years. Nitrates on this property are elevated and may be an indicator of a nearby leaking tank, or other factors. We note the septic on the adjacent lot, lot 5 was installed in the 70s and is approximately 80-feet from that property’s well. Many of the neighboring septic’s are in the 25-30 year age range. Due to the exceptionally light use and nominal operating level, we are requesting that that the department consider issuing a COSA for this 30 year old septic tank. The tank is most certainly nearing the end of its useful service life, and we recommend it’s proactive replacement in the next 1-5 years. 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. Sincerely, Charles Balzarini, PE 6/16/26 Septic Tank Advisory Certificate of On -Site Systems Approval # OSC261199 Subdivision: KASILOF HILLS Block:8, Lot: 4A The septic tank for this property is 31 years old. The average life of an asphalt coated steel septic tank is 20 years. Typical replacement costs are $15,000 or more, not including engineering, surveying, MOA permitting fees or site restoration. Steel septic tanks utilizing "Coal Tar Pitch" coatings are subject to corrosion as the steel reacts to water and rusts. These tanks have a finite lifespan buried in the ground. These tanks can become structurally compromised and pose a health risk. They could collapse and/or leak untreated wastewater directly into groundwater. In the interest of protecting public health and the environment, the Municipality of Anchorage Development Services Department has issued Policy W.05 Standard of Care Regarding the Inspection of Steel Septic Tanks when Performing COSA Inspection. Please request a copy of this policy from the Department if interested. This advisory must be attached to all copies of the subject Certificate of On -Site Systems Approval. Mailing Address: P. 0. Box 196650 * Anchorage, Alaska 99519-6650 * www.muni.org Nitrate Advisory Certificate of On -Site Systems Approval # OSC261199 Subdivision: KASILOF HILLS, Block: 8, Lot: 4A A water sample revealed a nitrate concentration of 8.53 milligrams per liter (mg/Q. 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.
