The permit requirements for Illicit Discharge Detection and Elimination for Minimum Control Measure 3 (MCM 3) are defined in Section 4.2.3-4.2.3.12 of the Jordan Valley Municipalities (MS4) Permit; No. UTS000001

The following is a summary of the requirements for MCM 3.
  1. Maintain a storm sewer system map of the MS4, showing the location of all outfalls and the names and location of all State waters that receive discharges from those outfalls.
  2. Through an ordinance, or other regulatory mechanism, a prohibition (to the extent allowable under State, or local law) on non-storm water discharges into the MS4, and appropriate enforcement procedures and actions.
  3. Develop and implement a plan to detect and address non-storm water discharges, including spills, illicit connections, and illegal dumping to the MS4.
  4. Develop and implement standard operating procedures (SOPs) for: 

     

    • tracing the source of an illicit discharge.
    • characterizing the nature of, and the potential public or environmental threat posed by, any illicit discharges found or reported.
    • ceasing the illicit discharge, including notification of appropriate authorities, property owners, and technical assistance for removing the source and follow-up 
  5. Inform public employees, businesses, and the general public about the hazards associated with illegal discharges and improper disposal of waste.
  6. Promote or provide services for the collection of household hazardous waste.
  7. Publicly list and publicize a hotline or other local number for public reporting of spills and other illicit discharges.
  8. Develop a written spill/dumping response procedure, and a flowchart for internal use, including various responsible agencies and their contacts.
  9. Adopt and implement procedures for program evaluation and assessment.
  10. Train employees, at a minimum, annually on the IDDE program.
  11. Non-analytical monitoring.

3.1 Stormwater Facilities Maps
Year Executed: 2003
Reference Regulation:
4.2.3.1
Target Pollutants:
sediment, nutrients, trash, petrochemicals, household chemicals, organics
Audiences:
MS4 Employees, General Public, Contractors, Developers, Planners
Description:
Riverton City maintains an online stormwater system map and it is updated as land develops.  The map is maintained in GIS in the NAD 83 Utah Central State Plane Coordinate system.
Rational:
Riverton chose to maintain its infrastructure in GIS for its ability to attach information to map features.
Measure of Success:
Maintain Current Stormwater Facility Maps.  In this case keeping stormwater maps current is a success.
Responsible Staff:
Stormwater Manager
Support: GIS Specialist
Funding:
Stormwater Utility, General Fund
Facilities Maps:
Appendix:
Stormwater System Inventory
Conclusion:
2014-2015
The City GIS maps were updated on a regular basis including stormwater systems throughout the year and the online maps were updated multiple times.


3.2 Riverton City Code
Year Executed: 2011
Reference Regulation:
4.2.3.2, 4.2.3.2.1
Target Pollutants:
Fertilizers, pesticides, herbicides, typical residential landscaping and maintenance pollutants and debris, garage chemicals and petrochemicals and other similar waste.  Waste related to similar activities associated with commercial properties.
Audiences:
MS4 Staff, Residences, Developers, Contractors, Engineers and Planners
Description:
Riverton City updated Riverton City Code in 2011 to support the MS4 regulations.  These ordinances are; 13.20 and 13.25, Stormwater development and Stormwater Utility ordinance respectively.  There are also many existing Riverton City Codes (RCC) that also prohibit activities having negative impact on stormwater quality.
Rational:
Ordinance revisions specifically for MS4 regulations were necessary to implement the stormwater programs and enforcement.
Measure of Success:
Annually evaluate the programs and enforcement actions issues related to ordinance.  Make conclusions and recommendations to City.
Responsible Staff:
Stormwater Manager
Funding:
Stormwater Utility
Appendix:
Appendix:
SWMP Amendments  Includes ordinance revisions
Conclusion:
2014-2015
Ordinance does not specifically mention the use of City SWPPP template for CGP projects.  The result is some inequality between CGP operator’s and increased staff work load.  The City SWPPP template is a revised native State SWPPP Template that answers many of the questions by Operators.  Recommendation: Ordinance should require that CGP operator’s use the City SWPPP template to improve the quality of SWPPPs and create equality between CGP operators.  See 4.3 Land Disturbance Permit program for support documentation.


3.3 Dry Weather Screening
Year Executed: 2011
Reference Regulation:
4.2.3.3, 4.2.3.3.1, 4.2.3.3.2, 4.2.3.4, 4.2.3.5, 4.2.3.5.1, 4.2.3.6, 4.2.3.6.1, 4.2.3.7, 5.2.2, 5.2.2.1, 5.2.3, 5.3, 5.4
Target Pollutants:
All discharges affecting the quality of runoff
Audiences:
City Officials, EPA Regulators.  It can also be directed to residential, commercial and institutional public as support for education material
Description:
The program involves screening the City stormwater systems at least once on an annual basis.  This is an observational procedure not a physical filtering device.  In summary, program involves observing whether water is present when it should not be and any visual observations of polluted water or stains.  The procedure is defined by the Dry Weather Screening SOP and the dry weather screening locations are shown on Riverton City’s online Stormwater Facilities Map.
Rational: 
The regulation is a very specific for this requirement.  No other rational is necessary other that the screening process is described in the Dry Weather Screening SOP.
Measure of Success:
Maintain Dry Weather Screen Log.  Evaluate log and file a conclusion and recommendations annually.
Responsible Staff:
Stormwater Manager
Funding:
Stormwater Utility
Standard Operations Procedures:
Appendix:

Conclusion:
2014-2015
No questionable discharges have been discovered this report period or any prior.  Not changes to the program are recommended at this time.


3.4 Emergency Spill and Illegal Dumping Hotline
Year Executed: 2013
Reference Regulation:
4.2.3.9, 4.2.3.9.1, 4.2.3.10, 5.3, 5.4

Rational: 
A written plan is necessary to ensure a reliable, responsive and effective system to contain, discharges resulting from illegal dumping and spills. It is also necessary for a basis to document the proper implementation of the program.
Measure of Success:
Maintain an Emergency Spill and Illegal Dumping Hotline Log.  Evaluate log and file a conclusion and recommendations annually.

Description:
Riverton City through the Interlocal Cooperation Agreement has co-permitted with SLCo Public Education and Outreach Program.  Their program includes Household Hazardous Waste Disposal program that meets the requirements of this MCM.  The accountability is defined by Task 2 of Co-Permit Accountability Document.
Rational: 
Co-Permitting with SLCo on this item was the most efficient and effective way to inform and provided the public this vital MCM.
Measure of Success:
This program is co-permitted with Salt Lake County and is measured by Salt Lake Counties Program.  See Section 2.4, 2014-2015 Annual Report Jordan Valley Municipalities Report
