Phase II Stormwater Rules The Phase II Rule automatically covers on a nationwide basis all small MS4s located in urbanized areas (UAs) as defined by the Bureau of the Census (unless waived by the NPDES permitting authority).

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