The following discharges of non-storm water into the City's storm drainage system are generally exempt from the Prohibited Discharges listed in Section 8.80.206 of this chapter.

*Note: The City of San Bernardino requires that a "Non-Storm Water Discharge Notification Form" be submitted to the Development Services Department for approval of these discharges, five days prior to any planned discharges or, as soon as possible, for any unplanned discharges. The Notification Form is available from the Development Services Department counter. Monitoring may also be required for these discharges.
The Regional Board may issue Waste Discharge Requirements for discharges exempted from NPDES requirements, if identified to be a significant source of pollutants. The Executive Officer of the Board may also add categories of non-storm water discharges that are not significant sources of pollutants or remove categories of non-storm water discharges listed above based upon a finding that the discharges are a significant source of pollutants. In this case, the list of exempted discharges, above, would be adjusted accordingly.
