The owner would like to replace it with a new septic system. We are proposing to install a new septic tank, and a new drain field. The old plastic tank will be inspected and re-used or decommissioned per moa requirements. Our review of available documentation and field investigation show that this project will not adversely impact any nearby Wells, Wastewaterdisposal systems, replacement disposal sites, ordrainage flowing onto and off of the subject property. The lot is served by a public well and the proposed septic system will be installed outside of the well's 200' protective radius. Two Waivers are requested for this project: 1. The existing drain field appears to be 5'from the home foundation at the closest point and approximately 15' of it is within 10' of the foundation. The system has been in place since 1978 with no apparent ill effects to the home. Based on that, we believe this system should be left in place as a reserve system. The requested distance is 5'. 2. The proposed drain field will be installed cross slope. The elevation difference is only 1' so the system may be easily installed in the soil strata. Due to the small elevation differential, we are not preparing a cross section. We believe the waiver should be approved as approval will have no discernable impact on the function of the system or on this or adjacent properties, other than to place the drain field in a more desirable location for the owner. The finished ground surface will be regraded upon completion of the system. The waiver is requested for the system as shown on the plans. Included with this letter is a permit application and design package, including plans, specifications, and calculations. A test hole was excavated, howevera deeper test hole will be excavated to 16' deep during construction to verify soil conditions and the groundwater table. Thank you for your time in reviewing this permit request. Please do not hesitate to contact me at 907-854- 5558 or by email cqbalzariniqmail.com with any questions or concerns.
