CERTIFICATION & STATEMENT OF INSPECTION BY ENGINEER As certified by my seal affixed hereto and as of the validation date shown below, I verify that my investigation, based on procedures outlined in the Certificate of On-Site Systems Approval Guidelines, indicates that the on-site water supply and/or wastewater disposal system appears to comply with applicable Municipal and State codes, ordinances, and regulations in effect at the time of installation, unless noted otherwise. Name of Firm FIRST WATER CONSULTING Phone 907-350-9566 Engineer’s Printed Name CURTIS HUFFMAN, PE Date 10/22/2025 Comments: This investigation was completed in compliance with MOA guidelines, regulations, and best industry practices / methods. The assessment of the condition of the well and septic applies only to the conditions as of the day tested. The flow and absorption rates may change due to subsurface conditions that may not be observed from the surface, changes in land use, local soil characteristics, groundwater levels that may fluctuate during the year, quality of construction (workmanship & materials), the water usage of the family being served by the system and maintenance. The operational life of all well and septic systems are subject to these various and dynamic characteristics and are outside the control of the evaluator of the well and septic system. Therefore, any or NO estimate of how long a system will function satisfactory for current or future occupants or guarantee that no unseen encroachments, deficiencies or discrepancies exist can be given by First Water Consulting & 10/22/25 Municipality ®i \ pciiry-t S( P.O.

Granting of this waiver is justified since the existing field has been in operation since 2003 with no known issues or ill effects to the property or adjacent Lot 16 property. Also, the existing septic field is 20’+ away from this adjacent property and it is anticipated that the field will not impact the neighboring property. Please contact us if you have any questions.

The recommended well productivity under (AMC 15.55) for a 5 -bedroom residence is .52 gallons per minute or 150 gallons per day per bedroom. Although the subject well currently exceeds this minimum recommendation, the production capacity can fluctuate and may be insufficient to meet your needs.
