Nitrate Loadina Estimate <br />Nitrate loading scenarios have been created for each proposed parcel of the Site, <br />addressing the existing homes (Parcel 3) or potential future homes (Parcels 1, 2, and <br />4). The nitrate loading scenarios utilize the variables discussed previously, which <br />represent the estimated conditions and uses associated with this project. <br />The following table presents a summary of the assumptions for the nitrate loading <br />calculations for the Site, as presented in Plates 17 through 19. <br />Table 4.
