Urban Stormwater and MS4 Compliance: What EPA looks for in Municipal Audits

Andy Dinsmorer,

EPA Region 3, Water Protection Division

Abstract: EPA has been inspecting several Phase I (large and medium) and Phase II (small) MS4s in Region III each year since 2008. These inspections include a review of MS4 practices, ordinances, procedures, and records in an office setting as well as a field component with on-site visits to construction sites, post-construction best management practices (BMPs), municipal facilities, and stormwater outfalls. As a result of these inspections, EPA has observed numerous good practices and programs as well as many with deficiencies that have led to enforcement actions. In this presentation, Andy will discuss the basics of an EPA MS4 inspection, EPA’s expectations, positive programs and elements, as well as common problems and deficiencies.
