Deviations from the approved design drawings shall be coordinated and approved by the engineer conducting the inspections. 1.3 All construction procedures and material used to construct the system shall comply with Municipal and State regulations. 1.4 Unless specifically agreed otherwise, the homeowner shall be responsible for finish grading areas after the system is constructed and soil is compacted and mounded over the wide trench disposal field and the Septic Tank. 2.0 SEPTIC TANK 2.1 The 1000 gallon septic tank shall have two compartments and shall comply with Municipality of Anchorage Requirements. 2.2 The septic tank shall be set level and shall be bedded as necessary to prevent settling or shifting of the tank. 2.3 All pipe connections to the septic tank shall be made with waterproof mechanical couplings. A cleanout shalt be installed upstream of the tank within 5 feet of the house foundation. A double cleanout shall be installed downstream, within 5 feet of the septic tank. 3.0 SOIL ABSORPTION DRAIIQFIELD: 3.1 The soil absorption drainfield shall be a 5' x 52.5' x 5' deep trench with a total of 2.5 ft. of sewer rock, 2.0 ft. beneath the perforated.drain pipe. 3.2 The bottom of the excavation shall be level. Any compacted or smeared surfaces shall be raked to allow for proper infiltration of eluent. This includes both the sides and bottom of the trench. 3.3 Sewer rock shall be 0.5 - 2,5" screened gravel with less than 3% passing the #200 sieve. 3.4 Cleanout pipes and monitor tubes shall be 4" diameter and installed as shown on the plans. The portion of the monitor tube extending through the sewer rock shall be perforated. 4.0 ENGINEERING INSPECTIONS 4.1 A minimum of four engineering inspections will be required during construction of the system. One after the septic tank is set prior to its backfill, one after excavation of the absorption trench prior to placement of sewer rock, one after the distribution piping, cleanouts and monitoring tube are in place. The final inspection shall be after filter fabric is placed and the final grading are complete. 4.2 The contractor shall coordinate with the engineer at least 24 hours prior to start of construction. If the contractor desires, a site visit with the engineer prior to start of construction can be arranged. PROBABLE IMPACTS TO ADJACENT PROPERTIES A) WELLS The proposed wastewater disposal system is designed in accordance with current Municapality of Anchorage Wastewater Disposal Regulations. The proposed drainfield will be constructed in accordance with these regulations. The separation distance from wells on adjacent properties is greater than 100 ft. Therefore no unacceptable impacts are expected on the wells located on adjacent properties. B) WASTEWATER SYSTEMS The new drainfield will be constructed with good separation distance from systems on adjacent lots. Soils tests have shown the soil where the system is to be constructed is acceptable for and an on-site disposal system, therefore there should be no unacceptable impacts on adjacent wastewater disposal systems.. C) RESERVED SPACFISURFACE AND SUBSURFACE The large lot that this system will be constructed on has ample space, both surface and subsurface reserved for a replacement system. The proposed drainfield should not affect adjacent properties. D) DRAINAGE. The location of the drainfield will not interfere with any drainage. The area disturbed during construction of the field will be graded and sloped so as to not pond water. Therefore this system shouldn't adversely affect adjacent properties.

This inspection revealed a nitrate concentration of 5.24 milligrams per liter (mg/L) was reported for the property's well water sample. 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. 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.
