NR 216.002(10)
(10) "Illicit discharge" means any discharge to a municipal
separate storm sewer that is not composed entirely of storm water except
discharges with a WPDES permit or other discharges allowed locally.
NR 216.06(1)(b)
(b) Prohibit illicit discharges to the municipal separate storm sewer
system.
NR 216.06(1)(f) (f) Carry out all inspections, surveillance
and monitoring procedures necessary to determine compliance and noncompliance
with permit conditions including the prohibition on illicit discharges
to the municipal separate storm sewer system.
NR 216.06(3)(b)
(b) A description of any existing programs to identify illicit connections
to the municipal separate storm sewer system. Include inspection procedures,
methods for detecting and preventing illicit discharges, areas where this
program has been implemented and a summary of results.
NR 216.07(3)
(3) FIELD SCREENING. A field screening analysis for illicit connections
and illegal dumping at all major outfalls identified in the permit application,
plus any additional selected field screening point designated by the municipality
or the department. At a minimum, a screening analysis shall include a
narrative description of visual observations made during dry weather periods.
If any flow is observed, 2 grab samples shall be collected during a 24
hour period with a minimum period of 4 hours between samples. For all
samples, provide a narrative description of the color, odor, turbidity
and the presence of an oil sheen or surface scum as well as any other
relevant observations regarding the potential presence of non-storm water
discharges or illegal dumping. In addition, summarize the field analysis
results for pH, total chlorine, total copper, total phenol, and detergents
or surfactants, along with a description of the flow rate. Additional
field analysis may be conducted using other parameters, like ammonia,
to enhance the detection of illicit discharges. Where the field analysis
does not involve analytical methods approved under 40 CFR 136 or by the
department, the applicant shall provide a description of the method used
including the name of the manufacturer of the test method along with the
detection levels and accuracy of the test. The field screening points
shall be established using the following guidelines:
NR 216.07(7)(b)
(b) A program to detect and remove illicit discharges and improper disposal
of wastes into the municipal separate storm sewer system, or require the
discharger to obtain a separate WPDES permit. The program shall include:
NR 216.07(7)(b)1. A schedule to implement and enforce
an ordinance, orders or similar means to prevent illicit discharges.
NR 216.07(7)(b)2.
2. A strategy to address all types of illicit discharges. The following
non-storm water discharges or flows are not considered illicit discharges:
water line flushing, landscape irrigation, diverted stream flows, uncontaminated
groundwater infiltration, uncontaminated pumped groundwater, discharges
from potable water sources, foundation drains, air conditioning condensation,
irrigation water, lawn watering, individual residential car washing, flows
from riparian habitats and wetlands, dechlorinated swimming pool water,
street wash water and fire fighting. However, these discharges need to
be included in the strategy when identified by the municipality as significant
sources of pollutants to waters of the state.
NR 216.07(7)(b)4.
4. Procedures to be followed to investigate portions of the municipal
separate storm sewer system that, based on the results of field screening
or other information, indicate a reasonable potential for containing illicit
discharges or other sources of non-storm water. Procedures may include
sampling for the field screening parameters identified in sub. (3), testing
with fluorometric dyes or conducting inspections inside storm sewers where
safety and other considerations allow.
NR 216.07(7)(b)6.
6. A program to promote public reporting of the presence of illicit discharges
or water quality impacts associated with discharges from municipal separate
storm sewers.
1. A schedule to implement and enforce an ordinance,
orders or similar means to prevent illicit discharges.
