Stormwater Managment Plan

What is stormwater?

Stormwater is rainfall or melted snow that runs off impervious surfaces, such as rooftops, streets, sidewalks, and parking lots. Impervious, or hard, surfaces prevent the storm water from naturally soaking into the ground, where the soil would filter out pollutants. As it flows, storm water picks up pollutants from these surfaces. Common pollutants include vehicle exhaust products, brake and tire dust, oil and grease, sediment, salt fertilizers and pesticides, pet waste, and litter. Because storm water is untreated, these pollutants enter our waterways.

Clinton's stormwater runoff enters the Big Black River watershed. Four creeks disperse stormwater runoff to the Big Black River.

  • Straight Fence Creek
  • Little Baker's Creek
  • Baker's Creek
  • Bogue Chitto Creek
  • Smith Creek
  • Lindsey Creek

Regulatory Background

In 1987, Congress amended the Clean Water Act (CWA) to require implementation, in two phases, of a comprehensive national program for addressing storm water discharges. The first phase of the program, commonly referred to as “Phase 1” was promulgated on November 16, 1990. (55 FR 47990). Phase 1 in 40 CFR Parts 9, 122, 123, and 124 requires National Pollutant Discharge Elimination System (NPDES) permits for storm water discharge form a large number of priority sources including municipal separate storm sewer systems (MS4s) generally serving populations of 100,000 or more and several categories of industrial activity, including construction sites that disturb five or more acres of land.

The second phase, the Stormwater Phase II Final Rule, is the next step in EPA’s effort to preserve, protect, and improve the Nation’s water resources from polluted stormwater runoff. The Phase II Final Rule was published in the Federal Register on December 8, 1999 (64 FR 68722). The Phase II program expands the Phase I program by requiring additional operators of MS4s in urbanized areas and operators of small construction sites, through the use of NPDES permits, to implement programs and practices to control polluted stormwater runoff.

The Phase II Rule defines a small MS4 stormwater management program as a program comprising six elements, that, when implemented in concert, are expected to result in significant reductions of pollutants discharged into receiving bodies.

MS4 Program Elements

The six MS4 program elements, termed “minimum control measures,” include:

  • Public Education and Outreach
  • Public Participation/Involvement
  • Illicit Discharge Detection and Elimination
  • Construction Site Runoff Control
  • Post-Construction Runoff Control
  • Pollution Prevention/Good Housekeeping


City of Clinton Information

The City of Clinton through the MS4 Program and City Ordinances is tasked with implementation and enforcment of the MS4 Permit Plan. This includes providing information, construction permitting and control, enforcement, screening, and education related to stormwater.

The following ordinances pertain to stormwater protection and control:

Stormwater Ordinance – pertains to floods, retention, stormwater design etc.

Environment Ordinance – pertains to land disturbance, illicit discharge, dumping, and pollution.
