Introduction
This Illicit Discharge Detection and Elimination (IDDE) Program describes procedures and best
management practices to protect the Town of Oro Valley’s Municipal Separate Storm Sewer System
(MS4) from pollutants due to illicit discharges and illegal connections.
This Program complies with the requirement in Section 6.4.3 of the Arizona Department of
Environmental Quality AZDEQ Permit (AZG2016-002) “Arizona Pollutant Discharge Elimination
System General Permit for Stormwater Discharges from Small Municipal Separate Storm Sewer
Systems to Waters of the United States” which states:
“The permittee shall implement an IDDE program to systematically find and eliminate sources of
non-stormwater to its municipal separate storm sewer system and to implement procedures to
prevent illicit connections and discharges.”
Legal Authority
The purpose and intent of this IDDE Program is to ensure the health, safety, and general welfare of
citizens, and protect and enhance the water quality of watercourses and water bodies in a manner
pursuant to, and consistent with, the Federal Clean Water Act (33 U.S.C. 1251 et seq.), National
Pollutant Discharge Elimination System Regulations (40 CFR Part 122), and State regulations for
stormwater discharge (ARS Title 49, Chapter 2, Article 3.1) by establishing minimum stormwater
management requirements for the management of pollutants that are, or may be, discharged to the
municipal storm sewer system. Authority for this Program is the “Storm Water Quality Management
and Discharge Control Ordinance” described further in Town Code Chapter 15-24.
IDDE Program Responsibilities
The Town of Oro Valley Stormwater Utility Staff is responsible for development and implementation

Illicit Discharge Reporting
A) Training of municipal employees.
The TOV will help facilitate detection and prevention of illicit discharges and connections to the
MS4 through education and training of Town staff on potential sources and hazards associated
with these illicit activities. Selected staff are trained as Certified Stormwater Inspectors by the
National Stormwater Center or equivalent (we currently have 13). This training includes
identifying sectors of the public (by region, industry, neighborhood), most likely to contribute
illicit discharges, and to use this information to perform more effective inspections. The Town of
Oro Valley also annually trains every municipal Operations and Maintenance employee in
detection and reporting of illicit MS4 activity to the Stormwater Utility.
B) Solicitation of public reporting of illicit MS4 activity.
The TOV solicits public information and reporting of illicit discharges through both the SWU
office and the Town’s Constituent Services Coordinator (CSC). The Stormwater Utility manager
and CSC are the principle contacts for constituent concerns, and they coordinate on situational
assessment and potential resolution. Current and future means of information retrieval include e-
mail, telephone calls, letters, direct conversations, and a web-based reporting system.
C) When A Potential Illicit Discharge Is Reported.
Each time an illicit discharge is reported Town Staff will immediately determine what type of
discharge has occurred and whether it poses an immediate threat to public health or the
environment. The following considerations are made upon discovery of an illicit discharge.
What type of spill or discharge has been discovered?
How much material has been released?
Does the discharge involve a hazardous material and should the fire department or other
emergency responders be notified?
Is there imminent danger of this discharge or spill rapidly spreading to sensitive
environmental areas?
Should other agencies be notified?

Identifying Potential Town of Oro Valley Illicit Discharge Hotspots.
The Town of Oro Valley has identified priority areas most likely to have illicit discharges or
connections. The information helps field staff and managers decide where to conduct detailed field
investigations to pinpoint and eliminate illicit discharges and connections. The process includes
reviewing information contained in the Town’s Cartegraph/GIS database, gathering staff
knowledge of the Town’s watersheds, determining where illicit discharges have been reported in
the past, and compiling other information collected by field crews. The following section describes
priority areas already identified for future illicit discharge investigations, as w ell as procedures
that staff uses to conduct a more detailed office assessment if needed.
A) Priority Areas Identified.
The Town of Oro Valley has identified three main priority areas where illicit discharges have a
higher likelihood of occurring. These include:
The commercial corridor of State Highway 77 (Oracle Rd.) from Ina Rd. to Rancho
Vistoso Blvd.
The commercial and industrial corridor of East Innovation Park Dr.
The Commercial corridor of North La Canada Dr. between Lambert Lane and Naranja
Drive.
Within these priority areas, the Town of Oro Valley will investigate businesses or activities that
typically generate wastes that may contain fecal coliform bacteria, petroleum products, heavy
metals, oil and grease, and soapy washwater. The Town will conduct unannounced site
inspections, public education and outreach, and follow-up investigations at:
Businesses that generate pet waste (e.g., veterinary clinics, pet boarding centers, pet
stores, and animal shelters) and public parks.
Automotive service centers and gas stations.
Restaurants.
Grocery stores and commercial retailers.
Light industrial and manufacturing facilities.
Horticultural and plant nursery facilities.
In addition, when notified the Town will investigate failing septic systems at residential
properties and provide assistance or recommendations to homeowners to conduct repairs or
maintenance, or help them connect their homes to the sanitary sewer system. Figure 1 below
shows areas within the Town of Oro Valley where illicit discharges have a higher likelihood of
occurring.
B) Field Assessment in These Priority Areas.
Detailed procedures for field assessments are discussed in the Town of Oro Valley standard
operating procedure for outfall inspection. Information collected during dry weather outfall
inspections (e.g., outfalls where suspected or obvious illicit discharges are discovered) are used
to identify priority areas where follow-up investigations need to be pursued. Information
collected during routine MS4 asset inspections, health department inspections, and water quality
monitoring are also used to identify priority areas for future investigation. Maps are prepared to
assist with field assessment in these priority areas and include include the following information.

Eliminating Illicit Discharges.
Upon detection of an illicit discharge, the Town of Oro Valley will identify all responsible
parties and eliminate those discharges as expeditiously as possible through every legal avenue at
the Town’s disposal. When immediate elimination of an illicit discharge is not possible the
Town of Oro Valley will establish a schedule of elimination to expedite the removal of the
discharge to the maximum extent practicable. A report on discharge location, discharge volume,
dates the discharge took place, responsible parties, and mitigation techniques will be provided
annually to ADEQ as part of the Town of Oro Valley annual MS4 report.
Visual Monitoring.
The Town of Oro Valley has developed and implemented a visual monitoring program of
municipal outfalls. Included in this monitoring program are parameters for identification of illicit
discharges during both dry weather and wet weather inspection of municipal outfalls. Outfall
inspection during dry and wet weather includes records of:
Outfall identification
Personnel conducting the inspection
Time and date
Weather conditions at the time of inspection
Estimated flow rate (if applicable)
Apparent odor, color, and clarity of the water (if applicable)
The presence of floatables and other debris (if applicable)
Condition of the ground during dry weather inspection
Recording of nearby land use
A) Visual Dry Weather Outfall Monitoring.
The Town of Oro Valley has developed a standard operating procedure which clearly outlines
municipal outfall identification and inspection procedures.
B) Visual Stormwater Discharge Monitoring.
The Town of Oro Valley has identified 5 major outfalls strategically chosen for their close
proximity to dense commercial and urban residential land use. These outfalls will be monitored
at a minimum of four times per year (twice during storm events each rainy season). Procedures
for monitoring outfalls during storm events are clearly outlined in the Town of Oro Valley
municipal outfall identification and inspection standard operating procedures.
C) Follow-up Screening.
Quick and efficient correction of illicit discharges is accomplished through well defined
authority coupled with swift enforcement and follow-up measures. The Town of Oro Valley
standard operating procedure on elimination of illicit discharges clearly outlines follow up
inspection procedures for areas where illicit discharges have been confirmed and eliminated.
Indicators of IDDE Program Progress
An important component of the IDDE program is a tracking and reporting system. A summary of
the information collected for the tracking and reporting system will be included in the annual
report to Arizona Department of Environmental Quality. The information stored in the tracking
and reporting system will be evaluated on an annual basis at a minimum to adjust the IDDE
program as needed. The Town of Oro Valley currently uses Cartegraph and GIS software to
store and analyze data and produce maps. The following information should be tracked and
reported in Cartegraph\GIS to assist with annual report preparation and program evaluation.
