Greater Trinity River Bacteria TMDL I-Plan Project

In September of 2011, NCTCOG was tasked by the Texas Commission on Environmental Quality (TCEQ) with supporting the development of Total Maximum Daily Load (TMDL) Implementation Plan (I-Plan) in the Dallas–Fort Worth area of north central Texas. The intent of the I-Plan is to address bacteria levels in several segments of the Trinity River. The name of this effort is the Greater Trinity River Bacteria TMDL Project.  After more than a year of meetings with stakeholders, a draft I-Plan was submitted to the TCEQ in August 2012. In December 2013, TCEQ Commissioners approved the final version. The I-Plan is comprised of implementations strategies intended to reduce bacteria loading in the impacted river segments and tributaries.
