This Annual Report was assembled to detail the activities in Anne Arundel County for the County and State Fiscal Year (FY) beginning July 1, 2015 and ending June 30, 2016. These activities demonstrate compliance with the National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permit terms provided by 40 CFR 122.42(c). It describes the components of the stormwater management program and the associated implementation status. The County proposes no revision to the program at this time.

On February 12, 2014, the County was issued a new, Fourth-Generation, NPDES MS4 Permit. This report is the third Annual Report prepared under that permit.
