IDDE: Tracing Illicit Discharges

Purpose of SOP: | To provide a quick reference list of items to keep in mind during tracing activities to

efficiently and systematically identify the source of an illicit discharge.

Always:

é

Review / consider information collected when illicit discharge was initially identified (Incident
Tracking Sheet or Dry Weather Outfall Inspection Form).

@ Survey the general area / surrounding properties to identify potential sources of the illicit
discharge as a first step.
@ Trace illicit discharges using visual inspections of upstream points as a second step.
@ Document tracing results for future reference.
Whenever Possible:
@ Use weirs, sandbags, dams, or optical brightener monitoring traps to collect or pool
intermittent discharges during dry weather.
@ Smoke test or televise the storm drain system to trace high priority, difficult to detect illicit
discharges.
@ Dye test individual discharge points within suspected buildings.
@ Ifthe source cannot be found, add the location to a future inspection program.
@ Collect bacterial samples of flowing discharges to confirm/refute illicit discharge.
Never:
@ Never enter private property without permission.
@ Never put yourself in danger.

2.6.4 Discharges from Exempt Parties

Several categories of facilities are regulated by the USEPA for stormwater discharges
under other permits. Because these facilities are already responsible to one
enforcement authority for stormwater discharges, the municipality can exempt them
from their municipal ordinance. Ifa municipality encounters an illicit discharge that is
suspected or determined to be coming from an exempt party that is regulated under
some other stormwater regulation, the municipality should notify both the suspected
discharger and the enforcement authority for that discharger. The notification can be
verbal or in writing. Most municipalities have prior experience working with other
enforcement authorities for suspected violations of either state or federal law.

The following is a brief list of parties that are regulated under an alternate stormwater
program:

authority verbally or in writing of the activity. Standard Industrial Classification (SIC)
