Items covered in this training

• ? Best Management Practices (BMPs) for preventing
  stormwater pollution

• ? Who to ask questions?

3
Regulatory Background

• 1972 Congress enacts Clean Water Act
• - regulates wastewater pollution
• 1987 Congress amends Clean Water Act
• - To add regulation of stormwater pollution
• 1990 County of San Bernardino, County Flood
  Control District and 16 area cities are issued
  first municipal stormwater permit Permit
• 1996/2002 County of San Bernardino, County
  Flood Control District and 16 area cities are
  issued second and third generation permits

4
Municipal Stormwater Permit Requirements

• The current Permit outlines a schedule of
  monitoring requirements, best management
  practices, and conditions designed to promote the
  reduction of pollutants in stormwater discharges.
  
• ? County/City departments and employees are
  legally required to implement the Permit
• ? County/City could potentially face penalties
  for violating Permit requirements

5
Fines and Penalties

good idea its the law.

• ILLEGAL DISCHARGE

7
Public Facility Sources of Stormwater Pollution

• Maintenance Yards
• Hazardous materials
• storage facilities
• Fire and police stations
• Animal shelters
• Recreation facilities
• Transportation facilities

8
Field Program Sources of Stormwater Pollution

• Roads and streets operation and maintenance
• Plaza, sidewalk and parking lot maintenance
• Fountain, pools, lakes and lagoon maintenance
• Landscape maintenance
• Water, sewer, drainage system operations and
  maintenance
• Waste Disposal handling and Disposal

9
Potential sources Maintenance Yard
Loading, unloading, handling and storage of
materials

• Dispensing of fuels

Vehicle and equipment parking, maintenance and
cleaning areas
10
Potential Sources Hazardous Materials Storage
Facilities

• Improper storage and handling of wastes can allow
  toxic compounds, oils and greases, heavy metals,
  nutrients, suspended solids, and other pollutants
  to enter stormwater runoff.

11
Potential Sources Fire and police stations

• Filling and ASTs and USTs with fuels
• Vehicle washing and steam cleanup
• Loading, unloading, handling of hazardous
  materials
• Landscape, garden and general maintenance

12
Potential Sources Animal Shelters

• Loading, unloading, handling and storage of dead
  animals and animal wastes for off-site disposal
• Vehicle, equipment, material washing
• Landscape, garden and general maintenance

13
How does maintenance affect stormwater quality?

• Maintenance practices which remove sediment,
  trash and debris from roadways and storm sewers
  can help prevent flooding and related damage and
  erosion.

14
Stormdrain inspections

• During an inspection of stormdrain look for

• excessive silt build up
• erosion/unusual algal growth
• cracked or collapsed pipes
• misaligned joints and
• other problems such as a sheen on the water
  surface, discolored water or an unpleasant odor

When a problem is noted, record the location and
nature of the problem and notify your supervisor.
15
Non-stormwater discharges

• Washwater from non-stormwater discharges needs to
  be diverted from the stormdrain system.

16
BMPs Maintenance Yards

• Perform Maintenance Activities Inside
• Use Dry Cleanup Methods for Spills instead of a
  hose
• Use a Wet Mop for Routine Floor Washing
• Recycle Wastes
• Conduct Routine Visual Inspections

17
General field activity BMPs

• Protect stormdrain inlets and open manholes
  during road repairs to prevent slurry mixes, dust
  and debris from entering the storm sewers.

18
General field activity BMPs

• Protect stormdrain inlets and open manholes
  during road repairs to prevent slurry mixes, dust
  and debris from entering the storm sewers.

19
General field activity BMPs

• Cover stockpiles with a tarp away from drainage
  courses to prevent materials from being washed
  into streams

20
General field activity BMPs

• Avoid using water to cleanup. Mechanically sweep
  dust and debris following all activities. DO NOT
  wash residue into the stormdrain system

21
General field activity BMPsconcrete waste
management
Send wash out wastes into a temporary pit where
the concrete can set, be broken up, and then
disposed properly. Saw cut slurry should not be
allowed to enter storm drains or watercourses.
Residue from saw and grinding operations should
be picked up by means of a vacuum attachment and
disposed of in the trash.
22
BMPs Management of Pesticides, Herbicides and
Fertilizers

• Apply pesticides and herbicides in accordance
  with California Department of Pesticide
  requirements
• Read and follow manufacturers label
  requirements before each application
• Check sprinkler system for overflows into the
  streets and storm drain
• As much as possible, utilize safer alternatives
  such as insecticidal soaps and horticultural oils

23
BMPs What to do in case of a spill

• Follow spill response guidelines for you agency.
• Safety First - Dont Take Risks
• Stop the Spill at its Source
• Protect Drains and Storm Sewers
• Call the Fire Department, Regional Board (if
  necessary)
• Contact your stormwater coordinator regardless of
  size
• Spread Absorbent Material
• Dispose of the Spilled Material Appropriately

24
Municipal facilities should be inspected to note
the following

• Materials are properly contained, stored, and
  disposed of
• Areas where vehicles, equipment, and materials
  should be covered with a tarp, moved indoors, or
  provided with a drip pan while parked or stored
• Spills, leaks, and drips have been cleaned up
• Where absorbent materials need to be provided

25
Municipal Yard Inspections
Facility site inspections are used to observe and
document the extent of overall good housekeeping
and BMP implementation including the following
areas

• Outdoor areas where trash, waste, and scrap
  materials are stored
• Outdoor areas where new materials and supplies,
  especially liquids, are stored fueling islands
• Outside areas where vehicle/equipment maintenance
  is performed
• Areas immediately outside of buildings in which
  vehicle/equipment maintenance is performed and
• Areas where vehicle/equipment washing is
  performed.
