I build food and beverage plants for a living and see this question pop up every time I permit a new facility. Your city/county is looking for a mg/L measurement of each of these components in your waste stream. However since you are not operating yet it is tough to have a lab analyze a sample of your process waste/CIP or COP water. For BOD most city/county facilities like to see a measurement below 600 mg/L, this number may be more or less depending on sewer size and whether or not you are on a gravity type system or a force main(pumping station). It can be a very tough area to get thru because of the lack of data available on your waste stream. I usually find that they will work with me for the permitting stage if I am upfront with them and let them know that I will test when the facility becomes operational.
