No person shall discharge or cause to be discharged
into the MS4 any materials other than stormwater except as provided
herein. Unless specifically exempted, the commencement, conduct or
continuance of any illegal discharge to the MS4 is prohibited.
The following discharges are exempt from discharge
prohibitions established by these regulations, unless the Department
of Environmental Conservation or the City has determined them to be
substantial contributors of pollutants:
A. Dechlorinated water line flushing, fire hydrant flushing,
fire pump testing, utility flushing or other potable water sources,
landscape irrigation or lawn watering, existing diverted stream flows,
rising groundwater, uncontaminated groundwater infiltration to storm
drains, uncontaminated pumped groundwater, foundation or footing drains,
crawl space or basement sump pumps, air conditioning condensate, irrigation
water, springs, water from individual residential car washing, natural
riparian habitat or wetland flows, dechlorinated swimming pool discharges,
residential street wash water, water from fire-fighting activities,
and any other water source not containing pollutants. Such exempt
discharges shall be made in accordance with an appropriate plan for
reducing pollutants.
B. Discharges approved in writing by the SMO to protect
life or property from imminent harm or damage, provided that such
approval shall not be construed to constitute compliance with other
applicable laws and requirements, and further provided that such discharges
may be permitted for a specified time period and under such conditions
as the SMO may deem appropriate to protect such life and property
while reasonably maintaining the purpose and intent of these regulations.
C. Dye testing in compliance with applicable state and
local laws is an allowable discharge, but requires a verbal notification
to the SMO prior to the time of the test.
D. Any discharge permitted under an SPDES permit, waiver,
or waste discharge order issued to the discharger and administered
under the authority of the Department, 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 MS4.
The construction, use, maintenance or continued
existence of illicit connections to the MS4 is prohibited. This prohibition
expressly includes, without limitation, illicit connections made in
the past, regardless of whether the connection was permissible under
law or practices applicable or prevailing at the time of connection.
A person is considered to be in violation of these regulations if
the person connects a line conveying sewage to the municipality's
MS4, or allows such a connection to continue.
