Municipal Separate Storm Sewer
(It sounds cooler than MSSS)
Municipal Separate Storm Sewer
(It sounds cooler than MSSS)
Drains, ditches, curbs, and gutters that move stormwater from one place to another Does not connect to the sanitary sewer system and does not lead to a wastewater treatment plant System owned or
- perated by a
public agency, such as a city, town, county, flood control district, state, or federal agency
1972 Clean Water Act
Regulate pollutants discharged into water Implement pollution control programs Fund sewage treatment plant construction under the construction grants program Recognized the need for planning
1972 Clean Water Act
Good start, but…
Two of every five waterways are still
considered to be impaired by pollution What’s the problem?

Minimum Control Measures in your Stormwater Management Plan (SWMP)
Public education and outreach Public involvement and participation Illicit discharge detection and elimination Construction site runoff control Post-construction stormwater management in new development and redevelopment Pollution prevention and good housekeeping for municipal operations and maintenance
MCMs in your SWMP
Every MCM has its BMPs
Public education and outreach
Educate the community on the pollution potential of common activities Increase awareness of links between land activities, and local water resources Give the public specific actions that reduce stormwater pollution-potential Create a plan ID audiences (business, homeowners, schools) Newsletter Distribute educational materials
Every MCM has its BMPs
Public involvement and participation
Facilitate opportunities for direct action and volunteer programs Establish watershed groups and conservation corps teams Develop citizen positions on a local stormwater management panel Develop written program Public review of ordinances Involve target audiences
Every MCM has its BMPs
Illicit discharge detection
Develop a storm sewer system map Develop an ordinance prohibiting illicit discharges Create a plan to detect and address these illicit discharges Start an education program on the hazards associated with illicit discharges
Every MCM has its BMPs
Construction site runoff control
Develop requirements to implement erosion and sediment control BMPs Establish ordinances and procedures for reviewing construction site plans Establish procedures for inspections and enforcement of stormwater requirements at construction sites.
Every MCM has its BMPs
Post-construction SWM
Create strategies to implement a combination of structural and non-structural BMPs Develop an ordinance to address post-construction runoff at new developments Establish a program to ensure adequate long-term
- peration and maintenance
Every MCM has its BMPs
Pollution Prevention
Develop inspection and maintenance procedures and schedules for SWM BMPs Treat pollutants from transportation infrastructure, waste transfer stations, etc. Establish procedures for properly disposing of pollutants removed from the MS4 Identify ways to incorporate water quality controls into flood management projects.
Is my municipality eligible for coverage under PAG-13?
Are any of your small MS4s regulated? No Yep Does your regulated MS4 meet all criteria for General Permit Eligibility? Your municipality is eligible for coverage under PAG-13! Yep No MS4 Permit is needed No You must apply for an individual NPDES MS4 Permit
Municipalities are required to submit a Notice of Intent (NOI)
1.) Multi-Municipal Joint Application 2.) MS4 Operator Information 3.) Urbanized Area Information 4.) Description of Receiving Waters 5.) Stormwater Management Program Plan
NOIs have a timeline of 5 years
Contain measurable goals for the six MCMs Contain Best Management Practices for each MCM Enact or implement either: An MS4 Stormwater Management Ordinance A Model Ordinance from an applicable Act 167 Stormwater Management Plan An ordinance that satisfies an MS4 Stormwater Management Ordinance Checklist Submit a MS4 TMDL Plan if applicable
Stormwater Management Program Plans must:
Total Maximum Daily Loads
- Maximum
amount of pollution that a water body can receive and still meet water quality standards
Water supply Recreation Aquatic life Agriculture Designated Uses
Calculations consider: –Point source pollution –Non-point source pollution –Background –Margin of safety factor
Total Maximum Daily Loads
- Impaired waterways require pollution reduction
plans; MS4s considered point source.
- Tool to address past impacts.
