NOACA and local partners have developed new guidance materials to assist communities in updating their SWMPs to meet the requirements of the revised General Permit and to consider the adoption of best management practices to address pollutants.  

The guidance materials presented at the April 7, 2015 training included the following items:

  1. checklist guidance document for use by MS4 communities to review and update their Storm Water Management Programs (SWMPs) to Comply with Ohio EPA General NPDES Permit for Small MS4s #OHQ000003
  2. Community Identifier Table that all MS4s to look-up their community to determine which watersheds have USEPA approved TMDLs and what pollutant types of TMDLs apply to their community.
  3. Once a community has identified the types pollutants that have been identified in the TMDLs, the MS4 can utilize pollutant-specific Fact Sheets to identify and adopt Best Management Practices for each of the SWMP Minimum Control Measure (MCM) requirements.
