Watershed Symposium 2018

TMDL/Stormwater Approaches for Restoring Water Quality

Summary:
Utah is currently developing the Lower Jordan River TMDL, which will affect municipal stormwater discharges. The State of Maryland has a similar program to meet the Chesapeake Bay TMDL. This presentation will both Utah and Maryland's approaches and give examples how permittees are implementing requirements.

Full Abstract:
This presentation will focus on Utah’s approach to working with MS4 permittees to fulfill permit obligations for discharges to impaired waters. All Utah MS4 permits have the requirement to document stormwater discharges to impaired waters and to comply wiith TMDL conditions. Utah is developing this approach for the Lower Jordan River TMDL and anticipates the TMDL will be finalized in 2020, which will require MS4’s to prepare and implement a plan to meet pollutant discharge goals. While Utah is currently preparing the TMDL, Maryland has already implemented MS4 permit conditions and prepared stormwater discharge goals for MS4 in compliance with the Chesapeake Bay TMDL. The Maryland program will be reviewed as well as one County’s approach to meeting their permit requirements, through their retrofit program.
