What is an MS4?
  • A conveyance or system of conveyances...owned by
    the U.S., a state, city, county, town, or other
    public entity that discharges to waters of the

    permit.
  • Add provision allowing changes to BMPs
  • Clarify SWMP responsibility for MS4 operators
    without authority to develop ordinances or
    implement enforcement actions

    would not be regulated under permit
  • e.g. office buildings and ISDs
  • TCEQ Review Period for SWMP
  • Public Participation requirements

  • possible public meeting

46
Proposed Requirements Beyond Federal Regulations
  • TCEQ determined certain additional requirements
    necessary to show compliance with the SWMP
  • Includes the following proposed requirements
  • List groups considered for Public
    Education/Outreach, and document those not
    considered.
  • List source(s) of information used to develop
    outfall map
  • List construction site notices and NOIs
