Purpose of the meeting
The fourth meeting of the Technical Advisory Committee (TAC) for Sand Branch Total Maximum Daily Load (TMDL) Study will be held on June 24, 2021. Biological monitoring data collected by the Virginia Department of Environmental Quality (DEQ) have shown that Sand Branch, located in Loudoun and Fairfax Counties, does not meet Virginia’s water quality standard for aquatic life use due to poor health in the benthic biological communities. TMDLs will be developed for sediment, total dissolved solids and total phosphorus, which were identified by the benthic stressor analysis as probable stressors contributing to the poor health of the benthic community. The purpose of this TAC meeting is to share and discuss the TMDL development process, including the approach to develop TMDL thresholds for each of the three pollutants, and model development. If you have any questions regarding the TAC, this meeting, or the Sand Branch TMDL Study, please contact Sarah Sivers via phone, email, or conventional mail using the information listed at the bottom of this notice.
