Box 196650 Anchorage, AK. 99519 To: Ms. Julie Makela 14 Sept 04 Reference: Variance in design. Please accept my apology for not notifying your office with changes to the design drawings for the septic system installed at track B2A-2 of the Knox subdivision and for not notifying you prior to the inspections that were made. This will not happen again in the future. After reviewing the well log, which showed the water table at 28 feet below grade, it was decided to allow the owner to excavate to the 11 -foot mark, 1 additional foot from the design drawings. This was done in an effort to make sure the system was installed in a manor that would function the best. I have reviewed all of the comments on the comment sheet and believe I have corrected all discrepancies. 71/,1,v� Sincerely, William E. Wood, P.E. Job No.: 04-114 M -W Drilling, Inc. .P.O.

Box 196650 Anchorage, AK. 99519 TO: Mr. Jim Cross REFERENCE: S-10937 Knox Subdivision Per your request, a test hole was excavated and percolation test performed. In addition a 7 -day water monitoring test was also performed. The approximate location of the test hole is in the reserve area of tract B2A-1 as show on the attached site plan. At the time of the excavation no water was encountered in the test hole and after seven day ground water monitoring, the monitoring tube was found to be dry. This property has enough area for future septic upgrade and should have no impact on any surrounding properties. If you require additional information, please contact me at 552-2878. Sincerely, 4/ C WILLIAM E. WOOD, P.E. ON-SITE WASTEWATER DISPOSAL SYSTEM CONSTRUCTION PRACTICES MATERIAL SPECIFICATIONS REFERENCE: Parcel B2A-2, Knox Subdivision GENERAL: 1. The scope of this project includes the installation of a 1500 gallon septic tank and two spill-over drain field trenches to serve the four bedroom residence located on the referenced property. 2. 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 owner shall be responsible for obtaining any necessary underground utility locates. 4. The property owner shall be responsible for final grading areas subsequently depressed from soil settling. On all leach field mound systems, the property owner shall be responsible for ensuring a satisfactory vegetation growth over the mounded area. 5. Owners installing their own systems must receive prior approval from the Municipal Health Department and the system must be designed and inspected by a registered engineer for the state of Alaska. SEPTIC TANK INSTALLATION: 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. All standpipes on the septic tank shall extend a minimum of 12 inches above final grade. 4. Septic tanks installed with less than 4 ft. of cover shall be insulated. 5. A foundation cleanout shall be installed one to four feet from the building foundation in the line between the tank and the leach field. There shall be two adjacent cleanouts. 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 leach field. The second cleanout shall be to clean toward the septic tank. 6. Final grading over the septic tank shall be such that a positive slope exists away from the septic tank. ABSORPTION TRENCH/DRAINFIELD INSTALLATION: 1. 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 before gravel (sewer rock) placement. 2. 2 feet of sand shall be placed in the bottom of the excavation prior to installation of the gravel. 3. 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. 4. 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. 5. 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. 6 Backfill over the final gravel layer must not be less than twenty five (25) 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. 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: 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. 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. MINIMUM MATERIAL SPECIFICATIONS: 1. Any septic tank proposed for installation must be constructed by a Municipally approved septic tank manufacturer. 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) ASTM D2662 (ABS) Yes No 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). 5. A permeable nontoxic silt barrier (Typar 3401, Mirafi 140N, or equal) must be installed between the fmal leach field gravel layer and the native soil backfill. 6. All leach field 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 AMC 15.65.060D. MUNICIPALITY OF ANCHORAGE Department of Health and Human Services P.O.

Box 196650 Anchorage, AK. 99519 TO: Mr. Jim Cross 9 June 2003 REFERENCE: Owner Intent to Install Septic System This letter is to serve as my intent to install my own septic system. I will be installing a 1500 gal. steel tank purchased from Anchorage Tank and all associated piping. I have the use of a 320B track excavator, D3 bulldozer, and 420 Cat excavator and have operated them for the past three years. I own a laser level that I will use to make sure the drain field is level and installed properly. I have had training in heavy equipment operation from the U. S. Air Force as well as working for a private individual and feel confident that I can excavate the trench required for the proper installation of a septic system. Mr. William Wood a registered professional civil engineer for the State of Alaska will be monitoring the installation of the system. He will approve the system once completed by filling out all the appropriate paperwork needed by the Municipality. If you have any further questions, please call me at 753-3040.
