The reason Services may be held on Saturday or Sunday is due to the fact that the Church's Priest travels between Parishes, and therefore may be available on one day of the weekend, but not the other weekend day, for any given week of the year. Additionally, it is my understanding that special events such as weddings, etc. that were originally stated in the Use Permit will occur, but at this point in time, it is unknown how many times per year. V The existing residential structure will be used as an office although there will be no one (e.g., Secretary, Priest, etc.) in the building during the week. Consequently, the effluent flows will be an absolute minimum and will occur only on the weekends. This is discussed in Section D below, on Page 11. t There will be food preparation within a designated kitchen area within the future Church. The San Joaquin County Onsite Wastewater Disposal Standards assigns 5 gallons wastewater per seat (person)when there is no kitchen, and 10 gallons per seat (person) when a kitchen is available within the Church. This additional 5 gallons of a Parishioner's individual water use accounts for water use that may occur in the kitchen, and for additional water use that will occur at special events such as weddings. Note: The actual number of seats within the new building is currently unknown; only the maximum number of Parishioners (125). Therefore, considering the total number of people'on a weekly basis, we have: 125 people x 10 gals/person x 1 d/week(Saturday or Sunday) =' 1,250 gals 3 Total projected wastewater flow per week — 1,250 gallons/wk Total projected wastewater flow per year= 1,250 gallons/wk x:52 weeks/yr= 65,000 gals/yr Wastewater Characteristics i 1 Blackwater will originate from toilets and graywater from hand washing and kitchen dishwashing. The potential for a higher organic loading exists when a kitchen facility is part of the Church. However, it is imperative that in order to reduce this potential higher loading, that all food wastes be handled as solid wastes and disposed of as such. Pursuant to EHD requirements, a food grinder or disposal will not be allowed to be installed in the kitchen sink, thus forcing the disposal of food wastes as solid wastes. itional wastewater constituents may consist of other liquids to the system, such as coffee,juices, etc. No industrial or commercial chemicals, solvents, etc. should be introduced into the wastewater treatment system. From the anticipated characteristics described above, the nitrogen emanating from the project should be a similar concentration than what would normally be found in a typical domestic or household system. The scientific literature cites nitrogen concentrations in domestic septic effluent typically ranging from 17 mg NIL for basins, sinks, etc. to 140 mg NIL for toilet wastes and a small volume of foo stes that may be introduced into the system through dishwashing. Therefore, considerin a 3515 percent usage for toilet/•is washing-hand washing water volume and hand ` wash wat e, respectively, a value ct§Og NIL (35% of 140 mg N/L plus 55% of 17 mg N of septic effluent will be used to calculate nitrate-nitrogen loading for this project. A value of Vaplan g NIL is typically used for residential calculations, as indicated in the scientific literature (see -Septic Systems Handbook,Pg. 147). S 5� 35� 11/� Chesney Consulting
