This fact sheet profiles the Construction Site Runoff Control minimum
control measure, one of six measures that the operator of a Phase II
regulated small municipal separate storm sewer system (MS4) is
required to include in its stormwater management program to meet
the conditions of its National Pollutant Discharge E mination System
(NPDES) permit. This fact sheet outlines the Phase II Final Rule
requirements modified December 9, 2016 and effective on January 9,
2017. It offers some general guidance on how to satisfy them. It is
important to keep in mind that the small MS4 operator typically has a
great deal of flexibility in choosing exactly how to satisfy the minimum
control measure requirements in ts NPDES permits.
