PRESENTATION OUTLINE

• Stormwater Program Update
• Stormwater Overview
• Sources and consequences of pollutants
• Education Program
• Discussion

2
Why Stormwater?

• 1972 Clean Water Act
• Established permitting program to protect water
  quality
• 1987 Water Quality Act
• Established a phased approach for stormwater
  discharge regulations
• 1989 Lawsuit NRDC vs. EPA
• 1992 Phase I and II Stormwater Regulation
• 1995 Salt Lake County, Salt Lake City, UDOT
• Required to implement a Storm Water Management
  Plan
• 2003 Phase II Regulations
• Small municipalities will be required to obtain a
  permit
• UPDES Permit effective through 2011

3
UPDES Permit for Jordan Valley Municipalities
includes

• Salt Lake County ,Bluffdale City, Herriman City,
  Holladay City, Midvale City, Murray City,
  Riverton City, Sandy City, South Jordan City,
  South Salt Lake City, Taylorsville City, West
  Jordan City, and West Valley City

4
Stormwater Management PlanRequired Control
Measures

• Public Education and Outreach
• Public Involvement/Participation
• Illicit Discharge Detection and Elimination
• Construction Site Stormwater Runoff Control
• Post-Construction Stormwater Management in New
  Development and Redevelopment
• Pollution Prevention/Good Housekeeping for
  Municipal Operations

5
OVERVIEW

• What is stormwater?
• Where does it go?
• Why does stormwater pollution matter?
• What can we do?

6
WHAT IS STORMWATER?

• Produced from Rain, Snow, Sleet, Hail, Snowmelt
• As stormwater runoff washes over streets, yards,
  etc. it carries pollutants with it
• STORMWATER IS NOT TREATED!

7
WHERE DOES STORMWATER GO?

• Collected and conveyed to canals, creeks, rivers,
  lakes
• Mill Creek
• Parleys Creek
• Big Cottonwood
• Little Cottonwood
• Jordan River
• Great Salt Lake

8
WHY DOES IT MATTER?

• How do human activities alter stormwater runoff?
• Increase volume of runoff
• Increase pollutants
• Consequences of poor stormwater quality
• Decline in fisheries
• Habitat disruption
• Swimming / water use restrictions
• Municipal Employee Responsibility
• Provide good water quality
• Protect beneficial uses
• Set good example for public
• Comply with new regulations

9
MAJOR CONTAMINANTS OF CONCERN

• Sediment
• Oil and Grease
• Heavy Metals
• Organic Debris
• Bacteria/Viruses
• Nutrients
• Hazardous Materials
• Floatables

10
CONTAMINANTS OF CONCERN Sediment

• Sources
• Roadway runoff
• Pavement wear
• Vehicles
• Road maintenance
• Construction
• Pumping groundwater
• Consequences
• Reduces light penetration
• Impairs sight feeding fish
• Increases drinking water treatment costs
• Clogs fish gills
• Covers streambeds

11
CONTAMINANTS OF CONCERNOil Grease

• Sources
• Leaking engines
• Restaurant grease traps
• Waste oil disposal
• Streets and Highways
• Parking lots
• Machinery Storage
• Illegal dumping
• Consequences
• Toxic to aquatic
• organisms
• Coat fish gills
• Can clog drainage facilities

12
CONTAMINANTS OF CONCERNHeavy Metals

• Sources
• Automobile body rust, brakes, tire wear
• Steel highway structures
• Galvanizing
• Chrome Plating
• Painting
• Scrap yards
• Automobile emission fallout
• Consequences
• Toxic to aquatic life (and potentially humans) in
  excessive quantities
• Potential contamination to drinking water supplies

13
CONTAMINANTS OF CONCERNOrganic Debris (Oxygen
Demanding Substances)

• Sources
• Yard waste
• Animal waste
• Litter
• Animal excrement
• Sanitary sewer overflows
• Consequences
• Use dissolved oxygen in the water when they decay
• Can cause fish kills
• Can limit recreational use of water

14
CONTAMINANTS OF CONCERNBacteria / Viruses

• Sources
• Organic material
• Sanitary sewer overflows / leaks
• Animal excrement
• Restaurants
• Consequences
• Fish kills
• Human illness

15
CONTAMINANTS OF CONCERNNutrients (Phosphorus and
Nitrogen)

• Sources
• Fertilizer and Pesticide application
• Detergents
• Sand and Salt application
• Yard debris
• Garbage
• Animal Waste
• Failing Septic Systems
• Consequences
• Algae growth
• Odor problems
• Aesthetic deterioration

16
CONTAMINANTS OF CONCERNHazardous Materials
(Pesticides)

• Sources
• Insecticides
• Herbicides
• Fungicides
• Rodenticides
• Consequences
• Extremely TOXIC to aquatic organisms
• Can cause fish kills
• Human illnesses
• Bioaccumulation

17
CONTAMINANTS OF CONCERNFloatables (Litter)

• Sources
• Street refuse
• Industrial yard waste
• Consequences
• Aesthetic degradation
• Clog drainage system

18
WHAT CAN WE DO?

• Best Management Practices - BMPs
• Source Control
• EDUCATION
• Alter activities
• Enclose activities to prevent contact with
  precipitation / runoff
• Separate Activities
• Conduct high risk activities separately
• Pipe to sanitary sewer system
• Treatment
• Most expensive and often not practical
