The Maryland Department of the Environment (MDE) gave a proverbial lump of coal to 5 counties and eight municipalities on December 22, 2016, when it announced they were to be subject to the federal National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) Phase II permit for stormwater mitigation. The 5-year MS4 permit requires affected entities to mitigate stormwater runoff, such as by improving stormwater infrastructure and retrofitting a certain amount of existing impervious surface. Phase I MS4 permits are individually tailored to the jurisdictions they affect while the Phase II permit is a general permit containing the same basic requirements for all affected permittees. The MS4 permit program is overseen by the United States Environmental Protection Agency who has delegated administration authority in the state to the Maryland Department of the Environment.
The proposed permittees include:
- Queen Anne’s
- St. Mary’s
(These counties would join the two existing Phase II MS4 counties of Cecil and Washington. Ten other counties are subject to Phase I MS4 permits.)
- North East [Cecil]
- Perryville [Cecil]
- Rising Sun [Cecil]
- Indian Head [Charles]
- La Plata [Charles]
- Easton [Talbot]
- Boonsboro [Washington]
- Williamsport [Washington]
(These municipalities would join 20 other municipalities already subject to a Phase II MS4 permit. No municipality is subject to a Phase I MS4 permit.)
In addition to announcing the proposed permittees, MDE also unveiled its new proposed Phase II permit. Public comment on the proposed permit runs until March 30, 2017. MDE will also be holding a public hearing on the issue on February 6. From MDE’s Phase II MS4 webpage:
