I. Published Data in the San Joaquin County EHD Sewage Standards and scientific literature. 2. Number of bathroom fixtures correlated with bathroom use per capita for a facility. 3. Number of parking spaces for a facility. 4. Maximum number of people(e.g.,employees, customers,etc.)for a facility. 5. Historical wastewater flow data from an existing facility. A. The Sewage Standards assigns 30 gallons per person, per day for Office Buildings. B. The Sewage Standards assign 150 gallons per toilet, per day fixture for employee/public use. The number of employees and customers has been adequately determined as indicated on the attached Site Approval Application. But this does not determine how often the Men's and Women's restroom facility will be used on a daily basis during the operation of the packing and hulling facility. Consequently,the EHD Standard of assigning 150 gallons per toilet, per day is applicable. However,this EHD Standard was based on old style toilets using 5 gallons per flush. Contemporary toilets use 1.5 gallons per flush. EHD Wastewater flows projected from one toilet in each of the restrooms are equivalent to 400 flushes per day: (300 gals/day(2 toilets(Mens's/Women's)@ 150 gals/day each)- 1.5 gals/flush (low flow toilets/flush)=200 flushes/day)which incorporates an enormous safety factor,even when accounting for hand-washing. Wastewater Flow Characteristics There will be no cooking, or food production in any of the referenced buildings. Therefore, there should be no concentrated organic loading. The characteristics of the wastewater flow will be predominately blackwater from toilets, with a comparatively small volume of graywater from sinks, or other sources of graywater. Additional wastewater constituents may consist of coffee,juices or other similar type liquids to the system. No industrial or commercial chemicals, solvents, etc. are to be introduced into the septic system. From the anticipated wastewater characteristics described above, the nitrogen emanating from the project may be at a higher concentration than what would normally be found in a typical domestic or household system. This can be attributed to the lack of a dilution effect that graywater from showers, laundry, and dishwashing would provide from a household. The scientific literature cites nitrogen concentrations in residential septic effluent typically ranging from 17 mg N/L for basins, sinks, etc. to 140 mg N/L for toilet wastes. Therefore, considering a 70/30 percent usage for toilet water volume and sink water volume, respectively, a value of 103 mg N/L of septic effluent will be used to calculate nitrate-nitrogen loading for this project. A value of 66 mg N/L is typically used for residential calculations, as indicated in the scientific literature. B. CALCULATED NITRATE-NITROGEN LOADING The calculated nitrate-nitrogen impact to the soil and ultimately to the groundwater is difficult to determine due to the large number of variables involved, and variables unknown at this time. These include: 1.) Impact from upgradient nitrate sources, 2.)Variability in wastewater flows, nitrogen concentrations and dilution effects from effluent and stormwater recharge, 3.) Changes in groundwater directional flow and elevation, 4.) Denitrification potential within the soil environment and within the confined and unconfined aquifers and 5.) Potential landscape uptake of nitrogen. Various scientific methods exist to estimate nitrate-nitrogen loading. This Study uses the Hantzsche/Finnemore Formula to predict the average resultant concentration of nitrate-nitrogen in 7
