The attached site plan identifies the location of the home as well as the proposed well, septic location and alternate site. No conflicts exist between this proposed system and any other well or septic system, whether on this lot or adjacent lots. The ground surface on the lot has a mild slope from the north to the south. The slope is mild in the northern half of the lot but gets much steeper on the southern half. The proposed system is in the northern half. There are no slopes greater than 25% within 50 feet downslope of either the primary or alternate site. Contours are shown on the site plan showing the grade and direction of flow. Stormwater drainage will not impact this septic system. The new trench will be constructed parallel to the slope as much as possible. We dug test hole near the proposed system and took a sample from the labelled strata that the system will be in. This sample came back as ML, per the attached lab analysis sheets. The previous test holes done in the subdivision (by Northern Geotechnical Engineering) show similar soils, with various ML layers down to 20'. They note a slight strata change, with the same soils classification, at closer to 12'. The DEC allows for soils classified as ML to use an application rate of 0.45 gpd/sf. Because this is a CAT III system we propose an application rate of 0.5 gpd/sf. We are requesting the approval of this design application. The proposed system is a shallow bed system, 20' wide x 75' long with a total depth of 8.5'. With a bed this wide and deep they will be unable to build it with machinery. It will have to be built by hand, with workers using shovels, eliminating the risk of over compaction by the equipment tracking over it. We are requesting the approval to construct the bed using this design. Wells on this and adjacent lots are shown. The new system will be a minimum of 100' from all wells and surface water, and more than 5' away from the septic tank. The alternate site is located more than 6' away. Please refer to the attached test hole log, plan and profile pages for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.

Owner agrees to maintain remote monitoring of the AWWTS as required by the AWWTS approval. 3. Term. The term of this Agreement shall begin on the date of approval by the Municipality to operate the installed system, or upon transfer of title, and shall continue while the AWWTS is operational or until title is transferred. 4. Nonwaiver.
