4. EPA Regulations - Phase II Regulations promulgated in 1999 Discharges from small construction sites (>1 acre) Discharges from regulated Small municipal separate storm sewer systems (Small MS4s)

36. Permit Adoption Process 4 workshops End of public comment period* Public hearing (TBA) Anticipate adoption of permit at the hearing * The end of the public comment period will be announced at least 30 days prior to its close

37. Comments Submit written comments to: Small MS4 Permit Comments State Water Resources Control Board P.O. Box 1977 Sacramento, CA 95812-1977

38. Summary of Comments Funding! Funding! Funding! Monitoring language needs clarification… guidance becomes requirement resulting in the need for extensive water quality sampling The ESA provision may be used too broadly The definition of Maximum Extent Practicable must be consistent with EPA’s definition and with the definition in Water Quality Order 99-05 Time allotted to prepare the annual report is not enough

39. Summary of Comments (cont.) The public process for developing and refining the SWMP does not fit state/federal facilities The requirement to certify continuous improvement of the SWMP is difficult to demonstrate, unnecessary given the definition of MEP in the permit, and may subject Permittees to 3 rd party suites. Is the intent of Phase II to give municipalities some of the responsibility of implementing and enforcing the General Construction and Industrial permits?

40. Summary of Comments (cont.) Concern that Phase II will quickly move to Phase I standards How will TMDLs affect the storm water permit? Clarification of the relationship between the General Industrial permit and the MS4 permit is needed. The requirement to capture and treat or infiltrate 85% is too large.
