5. Data Review Committee 1. Refine the CIWQS SSO spill report form data fields 2. Re-design the SSO spill report form to be event not location based 3. What indices of Collection System performance should be used to compare collection systems in California?

6. Performance Indices Current index Current index # spills per 100 miles of pipe per year # spills per 100 miles of pipe per year Under 3 – Over 6 Under 3 – Over 6 Prospective Indices 1. Number of Spills (or Volume of Spills) per 100 miles of pipeline. 2. Number of Spills (or Volume of Spills) per capita.

7. Performance Indices 3. Number of Category 1 spills (or Volume of Spills); number of Category 2 spills (or Volume of Spills). 4. Number of Spills (or Volume of Spills) by pipe diameter or pipe area. 5. Number of Spills (or Volume of Spills) by volume class of spill.

8. Performance Indices 6. Separate out number of spills (or Volume of Spills) by portion of collection system pump station, force main, gravity, lateral. 7. Separate out spills (or Volume of Spills) caused by outside contractors. 8. Number of Spills (or Volume of Spills) by cause category (fog, roots, debris, etc.).

9. Performance Indices 9. Gallons Conveyed versus Gallons Spilled versus Gallons Recovered versus Gallons Reach Surface water. 10. Volume of Spills per Year by Total Volume Conveyed (measured or estimated based upon population served).

10. Miscellaneous Data shows that smaller pipes have more frequent SSOs Data shows that smaller pipes have more frequent SSOs Smaller systems tend to have more SSOs per mile than larger systems Smaller systems tend to have more SSOs per mile than larger systems Roots tend to be the primary source of SSOs statewide Roots tend to be the primary source of SSOs statewide A new reporting category (3) may be developed for very small SSOs. A new reporting category (3) may be developed for very small SSOs.
