NPDES MS4 Annual Report 2019

This Annual Report was assembled to detail the activities in Anne Arundel County for the County and State Fiscal Year (FY) beginning July 1, 2018 and ending June 30, 2019. 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.

This report also summarizes the monitoring programs implemented by Anne Arundel County, including data collection and analysis.

On February 12, 2014, the County was issued a new, Fourth-Generation, NPDES MS4 Permit and, in February 2019, was administratively continued until the next permit is issued. This report is the sixth Annual Report prepared under that permit.
