An engineer at AECS should be consulted prior to construction to determine the number of inspections that will be required and to explain what these inspections will involve. 2.0 SEPTIC TANK 2.1 If there is an existing septic tank, it may be used it if meets the capacity requirement for the residence and the approval of the MOA. 2.2 The septic tank shall be a UPC-approved two-compartment tank, constructed of 12 gauge steel with bitumastic coating and set level on undisturbed soil. If the tank is buried at a depth of 4 feet or less, it must be insulated with an overlying layer of 2 inch burial type polystyrene rigid board Insulation. 2.3 The septic tank and trench shall be a minimum of 2.4 2.5 2.6 2.7 100 feet from any private well or body of water, 150 feet from Class "C" wells, and 200 feet from Class "A" or "B" wells, unless otherwise specified. Less than the required separation distance must have prior approval or waiver by ADEC or MOA. The septic tank shall be a minimum of 5 feet from the house foundation, and a minimum of 5 feet from the absorption area. Piping shall be fitted with a mechanical watertight calder coupling on the outlet and inlet of the septic tank. Piping shall be 4 inch solid PVC ASTM D-$054 or cast iron, sloped a minimum of 1/4 inch per lineal foot. If the piping is buried at a depth of 4 feet or less, it must be insulated with an overlying layer of 2 inch burial type polystyrene rigid board insulation. Cleanouts shall be installed as designated and capped with air-tight rain caps (Jim Caps or equivalent), and extended a minimum of 1 foot above ground level. If a lift station is required it shall be a combination lift station septic tank per Anchorage Tank and Welding, Inc. design. Specifications and design drawings are on file with the Municipality and the engineer. 8.0 ABSORPTION AREA 3.1 The gravel for the trench shall be 0.5 to 2.5 inch, screened rock with less than $ percent passing the No. 200 sieve. Ail substitutes must have prior DHHS approval. 3.2 The bottom and sides of the excavation shall be raked with the backhoe blade to ensure that it has not been compacted during excavation. The bottom elevation shall be level. 3.8 Monitor standpipe(s) shall be placed as shown in the drawings, and shall be 4 inch rigid PVC ASTM D-$054, or cast iron. The section shown with holes may be 0.§ inch holes drilled on 6 inch centers on opposing sides of the pipe, or a regular section of perforated sewer pipe clamped to a solid secti~on with either a no hub coupling or a solvent joint. A rubber rain cap (Jim Cap or 3.4 3.5 3.6 equivalent) shall be installed over the top of the pipe, The distribution pipe shall be perforated 4 inch PVC with a minimum crush strength of 1500 pounds and shall meet the approval of DHHS for use as drainfield pipe. All distribution pipes shall be laid level. Trenches may be paralleled, but must have a minimum separation distance between the trenches of 10 feet or 2 times the gravel depth (which ever is greater). 75 feet is the maximum allowed linear length of any trench. If the final grade over the trench is less than 4 feet above gravel, insulation is required, using burial type polystyrene rigid board insulation. There shall be 1 inch of insulation for every foot of soil less than the required 4 feet of cover, but there must be at least 24 inches of soil cover even though insulation is used. The solid pipe extending from the septic tank to the dratnfield shall also have a minimum of 4 feet of cover or an equivalent layer of insulation to prevent freezing of the line. 3.7 Filter fabric is required. 4.0 INSPECTIONS 4.1 A minimum of two inspections are required for the installation of the trench. The first inspection will be of the open excavation to assure that the system is installed in the proper soil strata, correct depth and meet minimum specified design parameters. 4.2 The second inspection will be after placement of the gravel, monitor standpipe and distribution pipe to verify proper installation and position prior to backfill. 4.3 The inspection of the septic tank installation can be incorporated with any one of the above listed inspections. 4.4 The lift station will require either an MOA electrical inspection or certification by a licensed electrician, depending on whether the building code applies to this part of the city.

There is no log and the driller is unknown. The depth of the well casing is not known. The casing is' visible when the water level is down to 57' below the top of the casing. No adequacy test was done on the absorbtion system as the system is less than 2 years old and probing indicates little or no sludge in the tank. The house is in the final stages of construction and the system .u~s~~ since construction has been by workmen, not a normal household usage. S~n~erely, /~ D. R. DAYTON, P.E., R.L.S.
