Water management professionals are invited to a TRB webinar on Thursday, October 31, 2019, from 2:00 PM to 3:30 PM ET. The webinar features research from the National Cooperative Highway Research Program (NCHRP)’s Research Report 918: Approaches for Determining and Complying with TMDL Requirements Related to Roadway Stormwater Runoff.

Transportation agencies across the country are required to comply with Total Maximum Daily Load (TMDL) mandates to address water quality requirements. TMDL compliance is a legally enforced time-schedule-order and can be resource-intensive, but if planned and implemented well, compliance can be incorporated into day-to-day transportation business and operation practices. This webinar will provide background information and discuss strategies on compliance. Presenters will describe development of a TMDL program as well as tools and methods for tracking compliance. They will also share lessons learned from examples of state TMDL programs.

Some registrants will need to pay $95 to attend this webinar.  Sign into to view registration information.
