3
Storm Water Phase II

• In implementing the Clean Water Act, EPA requires
  that all owners/operators of small MS4s reduce
  the discharge of pollutants from a regulated
  system to the maximum extent practicable to
  protect water quality.

• Quality of life
• Drinking water usage of some streams
• Cleaner streets
• Reduced Operation Maintenance of drainage
  systems
• Land preservation

14
Storm Water Phase II

• Six Minimum Control Measures
• Public Education Outreach
• Public Involvement Participation
• Illicit Discharge Detection and Elimination
• Construction Site Runoff Control
• Post-Construction Management
• Municipal Pollution Prevention/Housekeeping

15
Pollution Prevention and Housekeeping

• It appears that this has been there for some
  time. The owner has an obligation to take care
  of this problem. We see this all too often.

16
Illicit Discharge Detection and Elimination

• I hope hes planning on cleaning this up after he
  is finished
• All City staff needs to be trained to let the
  public know that the property owner is
  responsible for this cleanup

17
Illicit Discharge Detection and Elimination

• Cleaning is important, however, where did this
  material originate from?

18
Illicit Discharge Detection and Elimination

• Grass and mud in gutter needs to be cleaned
  before it gets washed into storm sewer
• Most people dont see anything wrong with blowing
  their grass clippings into the street
• Education, in this case is very important

19
Construction Site Runoff Control

• The contracting sector of the community is intent
  on working whenever possible
• There are measures available to them to make sure
  that this site doesnt become a maintenance
  problem for others

20
Construction Site Runoff Control

• We see this often
• The mud was removed from this site, but much of
  it ended up in the Citys street
• Typically, the contractor will ask for the City
  to come back and clean up after theyve made the
  mess

21
Well done-Construction Site Runoff Control BMP
22
Construction Site Runoff Control

• This is how we used to do projects
• We are getting better at preventing the erosion
  and sedimentation of materials by requiring BMPs
  in our project plans and specifications

23
Pollution Prevention and Housekeeping

• This will affect both quality and quantity of
  water in storm sewer

24
Public Involvement Participation
25
Construction Site Runoff Control BMP needed

• Contractor or owner needs to clean gutter before
  the material is washed into downstream inlet

26
Construction Site Runoff Control BMP needed

• Contractor or owner needs to clean gutter before
  the material is washed into downstream inlet

27
Construction Site Runoff Control BMP needed
28
Construction Site Runoff Control BMP
29
Post-Construction Management BMP
30
Illicit Discharge Detection and Elimination

• Wash-out paint in gutter

31
Illicit Discharge Detection and Elimination

• Oil drippings on road

32
Post-Construction Mangement

• Trapped downstream sediment in drainage channel

33
Construction Site Runoff Control

• Silt fence and housekeeping needed

34
Post-Construction Management
35
Pollution Prevention and Housekeeping

• Trapped sediment needs to be cleaned out

36
Pollution Prevention and Housekeeping

• This will affect both quantity and quality of
  water in drainage channel. City maintenance is
  needed.

37
Construction Site Runoff Control

• Inlet protection needed as well as housekeeping

38
Construction Site Runoff Control BMP
39
Construction Site Runoff Control BMP needed

• Place the pile in the yard and use silt fence to
  keep dirt out of street.

40
Construction Site Runoff Control BMP needed
41
Construction Site Runoff Control BMP
42
Pollution Prevention and Housekeeping

• There are many barrels, construction debris and
  garbage located less than 500 from this stream.
  Housekeeping would be important here.

43
Illicit Discharge Detection and Elimination

• The Corps probably will get involved in this one.

44
Storm Water Phase II

• Public Education Outreach
• education /or outreach program
• storm water impacts
• individuals efforts to reduce pollution
• lawn and garden, household hazardous wastes, pet
  waste management
• target audiences, displays, brochures, PSAs

45
Storm Water Phase II

• Public Involvement/Participation
• minimum public notice requirements
• development, implementation, and review
• storm drain stenciling, wetland restoration,
  annual stream clean-up, Adopt-a-Stream
• volunteers for education, task forces,
  stakeholder meetings, public hearings, open
  houses

46
Storm Water Phase II

• Illicit Discharge Detection Elimination
• Up-dated storm sewer mapping
• regulatory mechanism for the prohibition of
  non-storm water discharges
• program detect and eliminate (including
  enforcement)
• inform/educate public employees, businesses, and
  general public

47
Storm Water Phase II

• Illicit Discharge Detection Elimination
• Household waste dumping
• Irrigation
• Groundwater
• Street and parking lot wash water
• Lawn Clippings
• Paint washout at curb
• Oil Change dumping at inlets or in backyard areas

48
Storm Water Phase II

• Construction Site Runoff Control
• Erosion/sediment control ordinance with sanctions
  for non-compliance
• Construction site waste control requirements
• Site plan review procedures
• Public input procedures and opportunities
• Site inspection and enforcement

49
Storm Water Phase II

• Construction Site Runoff Control
• Runoff Control
• Erosion Control
• Sediment Control
• Good Housekeeping

50
Storm Water Phase II

• Post-Construction Management
• long term OM (policies procedures)
• promote prevention vs treatment
• adopt BMP strategies appropriate for our
  community
• assess/revise existing programs and ordinances
• watershed-based planning, wetlands, open space,
  buffers, vegetation, reduced impervious surface
  area, education

51
Storm Water Phase II

• Pollution Prevention/Housekeeping
• Operation and maintenance program
• Employee training to prevent and reduce pollution
• Fleet building maintenance, MS4 maintenance,
  pet waste disposal, vehicle maintenance
  washing, lawn care, snow disposal, parking lot
  and street cleaning

52
Storm Water Phase II

• Biggest Issues to address
• Funding source-to do this right, we will need to
  increase funding. The creation of the Storm
  Sewer Utility is a step in the right direction.
• Staffing-to keep this on task, we need to have
  enough staff dedicated to keeping this project
  moving forward.
