3.1 Stormwater Facilities Maps Year Executed: 2004
Reference Regulation: 4.2.3.1
Target Pollutants:
sediment, nutrients, trash, petrochemicals, household chemicals, organics Audiences:
MS4 Employees, General Public, Contractors, Developers, Planners Description:

3.2 Program History
Mapleton City has followed the state SWPPP Template that answers many questions offered by operators.
Recommendation: The State SWPPP Template should be used to help improve quality and uniformity of SWPPP’s and create equality between CGP operators.
3.3 Dry Weather Screening and Storm Water Facility Inspections Year Executed: 2012
Reference Regulation:
4.2.3.3, 4.2.3.3.2, 4.2.3.4, 4.2.3.6.1, 4.2.3.7, 5.2.2, 5.2.35,5.3, 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
DISPOSAL
The program involves screening and inspecting the City stormwater systems at least once every 2 years and dry weather screen inspections once every 5-years. High Priority sites may be subject to more frequent inspections as once every 6 months. 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. Operational status of facilities. (Sumps, Inlet boxes outfalls etc.) The procedure is defined by the Dry Weather Screening SOP and the dry weather screening locations are shown on Mapleton City’s online Stormwater Facilities Map.
Rational:
The regulation is 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.

3.5 Program History 3.6 System Monitoring Year Executed: 2012 Reference Regulation: 4.2.3.3, 4.2.3.3.2, 4.2.3.4 Target Pollutants:
All non-stormwater discharges
Audiences:
General Public, MS4 staff
DISPOSAL
Rational:Discharges from illegal connections are random and difficult to find with dry weather screening programs, However Mapleton currently doesn’t own a Camera Truck to inspect lines. Therefore, visual monitoring is the best BMP and most practicable BMP at this time. Although Permitees are required to prohibit illicit discharges within their boundaries and to make appropriate actions to detect and address any violation they are not strictly liable for all Illicit Discharges in their permitted area.
Measure of Success:
Maintain an Illegal Connections Log. Evaluate incidences to prevent reoccurrences. Report when and how illegal connections where corrected.

Public Works Manager
Funding:
Stormwater Utility
Standard Operations Procedures:
Appendix:
Contact the Mapleton Public Works Stormwater Department at 801-489-6253 for the Illicit Discharge Report.
Conclusion:
DISPOSAL
No illegal connections have been found. A lot of this due to there being very few storm drain lines in the MS4.
