  1. Pretreatment, Pollution Prevention and Storm Water CommitteeCalifornia’s Storm Water Program Bruce A. Fujimoto State Water Resources Control Board February 25, 2004

  2. Regional Board Boundaries

  3. Storm Water Program • Industrial • Construction • Municipal

  4. Industrial Program • Reduce the discharge of pollutants in storm water runoff and non-storm water discharges from certain industrial sites

  5. General Industrial Permit • First adopted 1992 • Re-issued 1997

  6. Industrial Program • Necessity for coverage based on SIC • Currently coverage is required for SIC categories: • 1-9 • 11 if there is exposure

  7. Industrial Permit Requirements • BAT/BCT Standard • Water Quality Standards • Develop and implement Site Specific SWPPP that: • Identifies sources of storm water pollution • Reduces/eliminates non-storm water discharges

  8. Industrial Permit Requirements (cont’d) • Select BMPs to reduce/eliminate the discharge of pollutants • Develop and implement a monitoring program that includes wet and dry weather visual observations, and sampling and analysis of runoff from two storm events per year • Reporting

  9. Industrial Permit Reissuance • Current Permit has expired • Staff has conducted two informal workshops on a draft permit in 2003 • Issues raised include • BMPs vs. numeric limits • Group Monitoring • Mandatory submittal of SWPPPs • Chemical and visual monitoring • Safe Harbor

  10. Industrial Permit Rissuance (cont’d) • Major Changes • Organization of Permit • No-Exposure • Greater specificity of monitoring requirements • Increased reliance on EPA Multi-sector Permit

  11. Construction Program • Construction General Permit • Linear Permit

  12. Construction Permit • Construction projects disturbing 1 acre or more • Threshold lowered to 1 acre in March 2003 with amendments to existing permit • Expires in 2004

  13. All Construction Projects Disturbing 1 or More Acres - Require Permit Coverage Projects that are linear in nature disturbing 1-5 acres - Small Linear Permit Projects disturbing between 1 and 5 acres Projects disturbing over 5 acres

  14. Construction Permit Requirements • BAT/BCT Standard • Water Quality Standards • Develop and Implement site specific SWPPP that: • Identifies Sources of storm water pollution • Reduces/Eliminates non-storm water discharges

  15. Construction Permit Requirements (cont’d) • Select/implement BMPs to minimize/eliminate pollutant discharges • Develop and implement a monitoring program that includes wet and dry weather visual observations, and when appropriate a sampling and analysis of runoff program • Year round implementation

  16. Construction Permit (cont’d) • Reporting • Emphasis on source control • Requires an interative approach to BMP implementation

  17. Construction Permit (cont’d) • Expires in 2004 • Scheduled public hearing on March 30, 2004 • Purpose to receive comment on Fact Sheet amendments dealing with sampling and analysis requirements • Amendments provide guidance regarding sampling and analysis

  18. Construction Program Issues • Monitoring • Mandatory submittal of SWPPPs • Safe Harbor

  19. Municipal Program • Permitting operators of Municipal Separate Storm Sewer Systems (MS4s) • Comprehensive programs aimed at changing behavior

  20. Municipal Permitting • MEP Standard • Develop and implement SWMPs • Phased permitting • Phase I • Phase II

  21. Phase I - Medium and Large MS4s • Regulations promulgated in 1990 • 27 permits adopted by RWQCBs in major urbanized areas • Statewide Caltrans Permit adopted by State Board

  22. Phase I Requirements • Compliance with water quality standards through specified iterative implementation of BMPs • Design Standards (SUSMPs) for new development and significant redevelopment • Construction and industrial Inspections • Chemical monitoring

  23. Phase II - Small MS4s • Regulations promulgated in 1999 • Requirements for smaller MS4s, including non-traditional Small MS4s • General Permit adopted by State Board in April 2003 • NOIs to be submitted by Small MS4s • Designation of Non-traditional Small MS4s

  24. Small MS4 Permit Requirements • Develop and implement SWMP addressing 6 minimum control measures • Measurable Goals • Construction site inspections • Optional industrial site inspections • Supplemental Provisions • Specified Design Standards

  25. Municipal Issues • Safe Harbor • Definition of MEP • Consistency between regions • Numeric standards vs. BMPs • Funding • Court Cases

  26. Overarching Issues • TMDLs • BMP effectiveness • Fees • SIP/CTR
