Phase II Storm Water Management Program

• Slide information based on

  Separate Storm Sewer Systems and
• December 8, 1999 Federal Register Storm Water
  Discharges Final Rule

Phase II General Permit Definitions

• MS4 municipal separate storm sewer system

4
Phase II General Permit Definitions

• Small MS4 conveyance or system of conveyances

  streets, catch basins, curbs, gutters, ditches,
  man-made channels or storm drains)
• Owned or operated by the US, state, city , town,
  borough, county, district, association, or other
  public body (created by State law) having

  control districts or drainage districts or
  similar entity
• Designed or used for collecting or conveying
  storm water
• Not a combined sewer, part of a POTW, or discrete
  system

5
Phase II General Permit Definitions

• MS4 Operator the owner or public entity that is
  responsible for the management and operation of
  the municipal separate storm sewer system and is

• Permittee the MS4 operator authorized under the
  general permit

6
Phase II General Permit

• MS4s Eligible for Authorization by General
  Permit
• MS4s located in an urbanized area (by 1990 or
  2000 census) must obtain authorization for the
  discharge of storm water runoff and are eligible
  for coverage under the general permit.
• Designated MS4s notified by TCEQ

8
Phase II General Permit

• Regulated small MS4 operators must
• develop, implement and enforce a Storm Water
  Management Program (SWMP) to address the Minimum
  Control Measures
• Submit NOI and SWMP to TCEQ

9
Minimum Control Measures

• Public Education Outreach on Storm Water
  Impacts
• Public Involvement / Participation
• Illicit Discharge Detection and Elimination
• Pollution Prevention / Good Housekeeping for
  Municipal Operations
• Construction Site Storm Water Runoff Control
• Post-Construction Storm Water Management in New
  Development and Redevelopment
• Optional Authorization for Municipal Construction
  Activities

10
Minimum Control Measures
11
Public Education Outreach

• Public Education Program, or Equivalent Outreach
  Activities to Inform
• Residents
• Visitors
• Public service employees
• Businesses
• Commercial and industrial facilities
• Construction site personnel
• Document that reasonable attempt was made to
  reach all constituents within the MS4

12
Public Education Outreach

• Inform about
• Impacts of polluted storm water runoff on water
  quality
• Hazards associated with illegal discharges and
  improper disposal of wastes
• Ways to minimize their impact on storm water
  quality.

13
Public Education Outreach

• Recommended
• Use existing educational materials provided by
  EPA, State, environmental, public interest, trade
  organizations, or other MS4s
• See
• http//cfpub.epa.gov/npdes/stormwatermonth.cfm
• and www.cleanwaterclearchoice.org (local)

14
Public Involvement in SWMP Development

• Identify and implement a public involvement and
  participation program
• Allow opportunities for all constituents within
  the MS4 area to participate in the SWMP
  development and implementation

15
Public Involvement

• At a minimum, comply with State/Local notice
  requirements
• Document that sufficient opportunities were
  provided to involve all constituents interested
  in participating in the program process

16
Illicit Discharge Detection/ Elimination

• Develop, implement enforce program to detect
  eliminate illicit discharges
• Techniques to detect illicit discharges
• Regulate non-storm water discharges
• Enforcement procedures/actions
• Storm drainage system map

17
Illicit Discharge Detection/Elimination

• Storm Drainage System Map
• Locate storm sewer pipes, ditches, other
  conveyances (or at a minimum, the outfall's
  drainage area)
• Locate all major outfalls
• Inner Diameter 36 inches or equivalent or
  drainage area of gt 50 acres
• Inner Diameter 12 inches or drainage area gt 2
  acres in areas zoned industrial
• Name and locate all waters of the US that receive
  discharges from the outfalls
• Document source of information

18
Pollution Prevention/Good Housekeeping for
Municipal Operations

• Operation and maintenance program with goal of
  conducting municipal operations in a manner to
  prevent or reduce pollution in storm water runoff
• Controls to reduce or eliminate discharge of
  pollutants when the runoff from municipal
  operation is determined to be a significant
  contributor to the MS4

19
Pollution Prevention/Good Housekeeping for
Municipal Operations

• Examples of municipal operations areas
• Parks/open spaces
• Street maintenance
• Fleet and building maintenance
• Storm water system maintenance
• New construction land disturbances
• Municipal parking lots
• Vehicle and equipment maintenance and storage
  yards
• Water transfer stations
• Salt/sand storage

20

  pollution from municipal operations
• Structural control maintenance
• List activities, schedules, inspections
