OSER has two important roles in aiding Maryland to reach its goal to restore the Chesapeake Bay. OSER is responsible for tracking the County's progress toward reaching the Bay's Total Maximum Daily Loads (TMDLs) of nutrients entering the watershed. Every two years, this progress is communicated to MDE in our progress report, and can be found on our Publications and Resources page.
Additionally, OSER develops plans for implementing stormwater management practices in order to meet the MS4 permit requirements related to the Chesapeake Bay. Currently, OSER is working towards updating its TMDL Restoration Plan, which was first created in 2016.
