Municipal Separate Storm Sewer
• Owned or operated by a State, city, town, county, college or university…
• Designed or used for collecting or conveying storm water;
• Which is not a combined sewer; and
• Which is not part of a Publicly Owned Treatment Works (POTW)
Municipal separate storm sewer means a conveyance or system of conveyances (including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, man-made channels, or storm drains)
Municipal Separate Storm Sewer System
Single buildings with stormwater runoff or a storm sewer that connects to a permitted Phase I or Phase II Municipal Separate Stormwater Sewer System (MS4) is not included in the Phase II Process at this time.
Municipal Separate Storm Sewer System
Does Phase II apply to non-standard MS4s that discharge to another permitted MS4 (i.e., NCDOT, Charlotte, Durham, Fayetteville/Cumberland County, Greensboro, Raleigh, or Winston Salem)?
It Depends
MS4 that connects to another permitted Phase I or Phase II MS4 may be subject to Phase II, depending on the activities, potential exposure, the degree of regulation at the site, the system of conveyance and/or the stormwater runoff impact.
Stormwater Management Plan
• Public Education and Outreach
• Public Involvement and Participation
• Detect and Eliminate Illicit Discharges
• Control Stormwater Runoff from Construction Activities
• Control Post-construction Stormwater Runoff
• Pollution Prevention/Good Housekeeping

Stormwater Management for Colleges and Universities
• Phase II for Colleges and Universities
• State Stormwater Programs
• Industrial Facilities
State Stormwater Programs
• Land Disturbing Activities
• Twenty Coastal Counties• HQW and ORW Classified Waters
(High Quality and Outstanding Resources Water)
• Water Supply Watershed Protection Program
• Nutrient Sensitive Waters• 401 Water Quality Certification
Program (impacts to wetlands)
State Stormwater Programs
• New Development or Redevelopment
• Minimize Impervious Cover• Use Passive Stormwater Management
Controls (e.g., grass swales)
• Structural Controls (high density, e.g., stormwater retention)
• Approvals from State of Local Agency
