(2) Discharges specified in writing by the city as being necessary to protect public health and safety.
(3) Dye testing is an allowable discharge, but requires a verbal notification to the city prior to the time of the test.
(4) The prohibition shall not apply to any non-stormwater discharge permitted under an NPDES permit, waiver, or waste discharge order issued to the discharger and administered under the authority of the EPA, provided that the discharger is in full compliance with all requirements of the permit, waiver, or order and other applicable laws and regulations, and provided that written approval has been granted for any discharge to the storm drain system.
