MS4 Madness: Stormwater Compliance & Permitting Trends


  • Lisa A. Jeffrey - Hazen and Sawyer

An evaluation of the status of stormwater permits within the Bay watershed, comparing compliance strategies, progress, and challenges, provides valuable context for an individual MS4 permittee. This presentation will provide a comparison of the different approaches to permitting within the Chesapeake Bay watershed. Additionally, recent MS4 permits from outside the Bay watershed, including the Massachusetts Phase II permit, will be discussed and compared to Chesapeake Bay permitting trends. The New England permits, which are issued directly by EPA, are often considered to be an indicator of the trends that should be anticipated by regulated communities. As will be discussed, stormwater permits are not only becoming more onerous with regards to reporting and tracking of compliance efforts but also with regards to new levels of control and monitoring to ensure water quality improvements. The general industry consensus, that MS4 permits are becoming more like consent orders issued to the wastewater industry, will be evaluated through comparison. The impact of such potential permit trends on communities, stormwater budgets and programs throughout the watershed will be presented.
