The proposed upgrade will serve an existing four-bedroom (4) house. This lot and surrounding lots are served by private wells. Currently, there are no wells within 100’ of the proposed upgrade. 1. Soils: A test hole was performed on this lot by Pannone Engineering Services, LLC on 0 1/28/2025. Groundwater was not observed during the excavation of the test hole, and bedrock was not encountered to a depth of 16-feet below ground surface. Groundwater was observed in the test hole monitor tube at a depth of 13.5-feet below ground surface on 04/07/2025. Based on the results of the percolation test and overall soils appearance, an application rate of 0.8 gpd/SF was used for the design of a conventional wastewater treatment system in the area of the test hole . 2. Soil Absorption System Design. a. See Sheet 1 of the design package. 3. Surface Water: There is no surface water within 100 feet of the proposed septic system. 4. Topography: See attached site plan for area topography. 5. Drawing Markings: The Drawings are marked “For MOA Review Only”. When written notification that the review is complete and no further comments are received from MoA On-Site Department, the note will be removed and “For Construction” drawings will be issued. The proposed installation will not affect the future development of this or the surrounding lots. If you have any questions or concerns, please contact me at (907) 745-8200. Sincerely, SRP Steven R.

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. In conducting an adequacy test, I attempt to provide a thorough, conscientious engineering analysis of the system in accordance with ADEC & MOA guidelines and OF q regulations.
