Appendix C Summary of Responses from State Stormwater Coordinators On February 21, 2007, on behalf of the committee, Jenny Molloy of EPAâs Of- fice of Wastewater Management sent the following questions to a group of state stormwater program managers and received six responses (found in Tables C-1 and C-2). 1. For industrial and/or construction: do you have information on non-filers, i.e., folks who should have submitted NOIs, but did not? If so, how old are these data, and how do they compare to overall numbers of those with permit coverage? How did you find and/or estimate the number of non-filers? 2. Also for industrial and/or construction: do you have information on compli- ance rates? Yes, this is a really broad question, but something along the lines of: based on inspections (or monitoring data, or whatever metric you use), have you made any determinations on numbers of facilities out of compliance, or alterna- tively, in compliance? If so, define what you mean by compliance (paper viola- tions, SWPPP/BMP inadequacies, water quality standards violations, etc.).

APPENDIX C 577 In September 2007, the NRC Committee on Reducing Stormwater Discharge Contributions to Water Pollution sent the following survey to 50 state stormwa- ter program managers. Responses were received from 18 states, including at least one from every EPA region. The blank survey is shown below, and Tables C-3 through C-9 contain the statesâ responses. The NRC committee members will greatly appreciate receiving the following information from State Stormwater Coordinators. Please complete both sides of this form and return to Xavier Swamikannu, CalEPA, Los Angeles Regional Water Board, xswami- kannu@waterboards.ca.gov or Fax: (213) 576-6625.

How is compliance demonstrated (monitor- ing or other activity)? To whom is the SWPPP submitted? Can an MS4 perform an inspection of an indus- try within its boundary? What industries are considered "high-riskâ? Do BMP manuals exist for implementation guidance? No. of dedicated staff or FTEs
