Where can I go to for information on how to calculate storm water runoff volume if I am required to file a wastewater report for my storm water discharge?
A36: Individuals are directed to two web pages in order to obtain the data and/or formulas to use in determining storm water discharge volumes for reporting under the AWR program http://www.epa.gov/tri/report/ Go to Pages 45 and 46 under the SARA Title III 313 – TRI Reporting Forms and Instructions and use the calculation examples and formulas provided to determine storm water run-off volume http://www.noaa.gov The National Oceanic and Atmospheric Administration has precipitation data available on-line in order to determine precipitation amounts for your given geographic area. If other rainfall data is available from reliable sources, you may use those figures in determining rainfall amounts.
