1. What is your normal response to the SSO events listed?
2. What are your most significant maintenance problems?
3. What maintenance activities do you think are beneficial to
preventing dry weather and wet weather SSO’s?
4. What are the limitations for the various methods for finding
SSO’s?
5. What inspection methods do you think are effective in
identifying potential SSO locations?
6. Do you utilize any written protocols or procedures for
identifying or investigating SSO’s or potential locations of SSO’s?
7. Do you have any plans for developing protocols for identifying
or investigating SSO’s? Do you have any ideas for an effective
protocol?
8. Have you identified any recurring design deficiencies that may
be causing SSO’s (e.g., flat sewer slopes)?
9. Have you made any design changes to correct the above
problems?
10. What are the most common SSO defects fixed?
11. Do you expect SSO requirements to be added in the future?
12. Do you have an I/I management program?
13. Do you have a corrosion control program?
