Box 196650 Anchorage, Alaska 99519-6650 REFERENCE: Proposed Upper Eagle River Estates, Block 1, Lot 8A Request you issue a permit to replace the septic system serving the four bedroomhouseonthe referenced propert¥. The referenced property is to be subdivided as shown on the attached site plan. Subdivision Plat S9266 was approved, however a condition of the Plat imposed by your office required the undocumented system serving the house on the north half of the property be upgraded. The attached permit application is to satisfy your requirement. The subdivision plat expired as a result of the owner being severely injured and having to put the project on hold until he recovered. He is now ready to continue and has reapplied for plat approval. Test holes were excavated and percolation tests performed. The approximate locations of the test holes are located on the attached site plan. At the time of excavation no water was encountered and after seven day ground water monitoring, water was found at 9' and 12'. Attached is the proposed upgrade design. The proposed 1250 gallon septic tank is to be placed outside the well protective radius. Attached is a site plan which depicts the location of the proposed tank. We do not anticipate any adverse effects on neighboring properties by the installation of the proposed septic system.

The existing undocumented system and tank are to be abandoned completely. The existing leachfield is to be abandoned in place. 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. 3. 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. On all leachfield mound systems, the property owner shall be responsible for ensuring a satisfactory vegetation growth over the mounded area. 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. 1. A septic tank is to be constructed by a certified septic tank manufacturer. Construction shall include two 4" cleanouts for pumping access. 2. The septic tank shall be sufficiently bedded to prevent settling or shifting of the tank. 3. Ail standpipes on the septic tank shall extend a minimum of 12 inches above final grade. 4. Septic tanks installed with less than 4' of cover shall be insulated. Page Two Proposed Upper Eagle River Estates; Block 1; Lot 8A August 17, 1994 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' 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 TRENC~/DRAINFI~.D 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 (roughed-up) before gravel (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 and installed approximately in the locations shown on the design. The portion of the monitoring tube extending through the gravel shall be perforated from 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. 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 Mlrl.'lfalAL SP~CIFICJkTIONS: 1. Any septic tank proposed for installation must be constructed by a Municipally approved septic tank manufacturer. Page Three Proposed Upper Eagle River Estates; Block 1; Lot 8A August 17, 1994 2. The following pipe materials are approved for use in septic system installations in the Municipality of Anchorage: Type of Pipe Perforated Solid Cast Iron Yes Yes ASTM D3034 (PVC) Yes Yes ASTM F810 (HDPE) Yes No ASTM D2662 (ABS) Yes Yes Use of a type of pipe other than listed above must be approved by the inspecting engineer. 3. Insulation shall be at least 2" thick extruded direct burial polystyrene (Dow Chemical Company Styrofoam HI or equal). 4. Septic tank inlets and outlets shall be fitted with watertight couplings (Caulder, Fernco, or equal). Se A permeable nontoxic silt barrier (Typar 3401, Mirafi 140/N, or equal) must be installed between the final leachfield gravel layer and the native soil backfill. 6. Ail leachfield gravel (sewer rock) shall be 0.5"-2.5" screened gravel with less than 3% passing the ~200 sieve. 7. When sand is being used as a filter material, its gradation specifications must conform to current M.O.A. or D.E.C. requirements. 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: 1. 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. 2. 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. Page Four Proposed Upper Eagle River Estates; Block 1; Lot 8A August 17, 1994 3. 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, etc. 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 contractor's 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.O.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 contractor's activities. Final acceptance of the contractor's work rests with the owner and the M.O.A. 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.
