The intent of this article is to develop an effective program
to determine the presence of illicit discharges from storm sewer outfalls.
This article is adopted under the authority granted by § 61.354,
Wis. Stats.
This article shall apply to all water entering the stormwater
conveyance system or waters of the state generated on any developed
or undeveloped lands unless explicitly exempted by an authorized enforcement
agency.
As used in this article, the following terms shall have the
meanings indicated:
ILLICIT CONNECTION
Any connection that is either:
A.
Any drain or conveyance, whether on the surface or subsurface,
which allows an illegal discharge to enter the stormwater conveyance
system or waters of the state. This Includes but is not limited to
any conveyances which allow any nonstormwater discharge including
sewage, process wastewater and wash water to enter the stormwater
conveyance system or waters of the state. It also includes any connections
to the stormwater conveyance system or waters of the state from indoor
drains and sinks, regardless of whether said drain or connection had
been previously allowed, permitted, or approved by an authorized enforcement
agency; or
B.
Any drain or conveyance connected from a commercial or industrial
land use to the storm drain system which has not been documented in
plans, maps, or equivalent records and approved by an authorized enforcement
agency.
ILLICIT DISCHARGE
Any discharge to a stormwater conveyance system that is not
composed entirely of stormwater except discharges authorized by a
WPDES permit or other discharge not requiring a WPDES permit limited
to landscape irrigation, individual residential car washing, firefighting,
diverted stream flows, uncontaminated groundwater infiltration, uncontaminated
pumped groundwater, discharges from potable water sources, foundation
drains, air conditioning condensation, irrigation water, lawn watering,
flows from riparian habitats and wetlands, and similar discharges.
The owner or operator of a commercial or industrial establishment
subject to a WPDES permit shall comply with their permit, including
the development and implementation of a stormwater pollution prevention
plan (SWPPP).
If any section, clause, provision or portion of this article
is judged unconstitutional or invalid by a court of competent jurisdiction,
the remainder of the article shall remain in force and not be affected
by such judgment.
This article shall be in force and effect from and after its
adoption and publication. The above and foregoing article was duly
adopted by the Village Board of the Village of Osceola on the 12th
