We are therefore requesting a permit be issued for the construction of a new septic system to serve the new home. The attached Site Plan and backup documentation identify the location and configuration of the new septic system and the parameters used in the design. Also identified on the plans are the location of the water service on the lot, test holes and the septic systems on the surrounding lots. Drainage arrows are shown indicating the current drainage patterns. The drainage patterns will be maintained after construction. The existing septic system on the lot was previously demolished in accordance with Municipal and ADEC requirements. The test holes placed near the location of the proposed absorption trench indicated poorly gravel with some sand and cobbles to a depth of 7' and percolation rates approximating 2 minutes per inch. This material is underlain by a siltier well graded gravel with a slightly higher percolation rate. No groundwater was found during placement of the test holes, and none was noted during the monitoring period. We are therefore proposing to place a new 1,000 -gallon septic tank and a 38' long x 5' wide x 4' effective depth absorption trench. The distribution pipe will be placed 2' below the existing surface and the total depth will be 6. Sufficient fill will be placed over the septic tank and absorption trench to prevent freezing. The ground surface on the lot slopes at shallow grades from southeast to northwest. The absorption trench will be constructed parallel with the slope as much as possible in conformance with Municipal requirements. All components of the new septic system will be constructed a minimum of 10' from the water service on this lot and 100' from any surface water in the area. If the system is constructed in accordance with our design the following statements apply: Lot 1, Block 2, Wynter Park July 24, 2003 Page Two The system, if constructed as designed, will have no adverse impact on the wells in the area or those to be constructed in the future. 2. The system, if constructed as designed, will have no adverse impact on existing septic systems in the area or those to be constructed in the future. 3. The system, if constructed as designed, will have no adverse impact on reserve space, either surface or subsurface, on any lots located in the area. 4. The system, if constructed as designed, will have no adverse impact on drainage patterns in the area. The current drainage pattern will be maintained. Sincerely, Michael E. Anderson, P.E.

ANDERSON, CERTIFY THAT THIS TEST WAS PERFORMED IN ACCORDANCE WITH ALL STATE AND MUNICIPAL GUIDELINES ON THIS DATE: 7/24/2003 ON-SITE WASTEWATER DISPOSAL SYSTEM CONSTRUCTION AND MATERIAL SPECIFICATIONS SUBJECT: LOT 1, BLOCK 2, WYNTER PARK SUBDIVISION GENERAL: The scope of this project includes the procurement and placement of a new 1,000 -gallon septic tank at the location shown on the site plan. Work also includes the construction of a new absorption trench 38' long by 5' wide by 4effective depth also at the location shown on the Site Plan. The total depth of the trench will be 6' below existing ground and the distribution pipe will be placed at 2' below the surface. All components of the new absorption trench and septic tank must be constructed a minimum of 100' from any surface water and 10' from the water service on this and adjacent lots. A minimum of 4' of cover is required over the septic tank and 3' over the absorption trench. In lieu of cover 2" of direct bury insulation and 2' of cover may be placed. Construction shall be in accordance with the approved site plan, 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 all underground utility locates and for the layout of the septic system and verification of the location of all lot lines. 4. Unless specifically agreed otherwise, the contractor shall be responsible for final grading areas subsequently depressed from soil settling. Property owner shall be responsible for revegetation of affected areas unless specifically agreed otherwise. 5. Contractors installing wastewater disposal systems must be certified by the Municipal Department of Health and Human Services for system installations. Owners installing their own systems must receive prior approval from D.H.H.S. before beginning system installation. SEPTIC TANK INSTALLATION 1. A new 1,000 -gallon septic tank must be procured from a certified septic tank manufacturer if the existing tank is found to be defective. 2. A septic tank is to be constructed by a certified septic tank manufacturer. Construction shall include two 4" cleanouts for pumping access. 3. The septic tank shall be sufficiently bedded to prevent settling or shifting of the tank. 4. All standpipes on the septic tank shall extend a minimum of 12 inches above final grade. 5. Tanks installed without 4' of cover shall have a minimum of 2" of direct burial insulation. Lot 1, Block 2, Wynter Park July 24, 2003 Page 2 of 3 6. A foundation cleanout shall be installed one to four feet from the building foundation. Two cleanouts are required between the tank and the drainfield. 7. Finalgrading over the tank shall be such that a positive slope exists away from the septic tank. DRAINFIELD CONSTRUCTION: 1. The drainfield shall be constructed to the dimensions shown on the design. The bottom of the trench shall be within 2" of level. 2. Distribution piping must be placed level with perforations down atop a level bed of drainfield rock. Rock should then be placed over the pipe to provide a minimum of 2" of cover. 3. A silt barrier or geotextile fabric must be placed between the drainfield rock and the natural soil backfill. 4. Monitor tubes must be 4" in diameter and installed at the locations shown on the design. The portion below ground must be perforated. 5. Contractor shall verify the septic tank and drainfield are a minimum 100' away from any private water wells in the area, 150' from a Class "C" Well or 200' from any community well. 6. Direct bury insulation must be placed over the distribution system if less than 3' of backfill depth is available. Finish grade over the trench must be mounded to prevent settlement or depressions. 7. Grade area surrounding the absorption trench to drain away. 8. A minimum 2' of accepting soil is required below the drainfield rock for a 5' wide trench. Contractor shall verify this condition prior to placement of the rock. All pockets of unacceptable materials must be removed and replaced. MATERIAL SPECIFICATIONS: 1. Septic tanks 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: Cast Iron (perforated and solid), ASTM D3034 or P.V.C. (perforated and solid), ASTM F810 or H.D.P.E. (perforated, but not solid) and ASTM D2662 or A.B.S. (perforated and solid). 3. Insulation shall be at least 2" thick extruded direct burial polystyrene (Dow Chemical Co. Styrofoam HI or equal). 4. Septic tank inlets and outlets shall be fitted with watertight couplings (Caulder, Fernco, or equal). Lot 1, Block 2, Wynter Park July 24, 2003 Page 3 of 3 5. A permeable geotextile fabric (Typar, Mirafi or equal) must be installed between the final drain rock layer and the native soil layer. 6. All drain rock shall be .5" to 2.5" in diameter with less than 3% passing the #200 sieve. INSPECTIONS: Municipal Ordinance requires a minimum of two inspections. These inspections must be conducted under the supervision of a professional engineer registered in the State of Alaska. The first inspection must be conducted after the excavation of trenches, beds or pits and before the installation of any gravel. A septic tank may be set in place, but may not be backfilled. The second inspection must be conducted after the placement of the geotextile fabric, gravel, distribution piping, standpipes, cleanouts and insulation. No backfill should be in place at the time of inspection. Contractor shall provide a copy of all field survey layout and construction notes for use in preparing the certified as -built of the completed system.

H. If the system does not operate in conformance with the standards in this chapter, the department may re ui--e that t -he system immediately be brcught into compliance with this charter. I. After the period of the provisional per=it, the depa-dent shall evaluate the performance of the innovative system. If the system has perforred substantially in conformance with the standards in this chanter and is as effec`-ive or more effective :han conventional cn-site wastewater dispcsal systems, the deaar = ent shall permit the continued eperaticn of the system so long as the system continues to AC 2-6-21 (as ar..ended) Page 25 meet the standards c: this chapter, as amended.
