The study shall use rainfall data most near to the project site to get <br />accurate representation of potential nitrate loading to groundwater. <br />b) Per study, the proposed project will utilize 200 gallons of wastewater per day. EHD calculates nitrates <br />loading based on number of bedrooms with 100 gallons of wastewater being from the first bedroom <br />followed by 50 gallons for each additional bedroom. A four bedroom will result in 250 gallons, which <br />is greater than proposed 200 gallons per day. <br />Submit an addendum addressing above mentioned concern and EHD will respond accordingly. <br />If you have any questions please contact Naseem Ahmed, Senior Registered Environmental Health <br />Specialist, at nahmed@sjgov.org or (209) 616-3018. <br />Muniappa Naidu, REHS <br />Assistant Director <br />c: Baez Consulting &Jonathan Blas Loper Rodriguez- 1349 Anteros Ave, Stockton, CA 95215 <br />1868 E.
