On the Edwards Aquifer recharge zone, clearing and excavation are regulated activities under 30 TAC Chapter 213 and require approved erosion and sediment controls. Construction General Permit sites of one acre or more need a stormwater pollution prevention plan with erosion best management practices.
Erosion and sediment control in Williamson County is driven by two state programs. Over the Edwards Aquifer recharge zone, clearing, excavation, and grading that disturb site topography are regulated activities that require TCEQ-approved temporary and permanent best management practices. Statewide, any construction disturbing one acre or more must implement the erosion and sediment controls described in its stormwater pollution prevention plan under the TXR150000 Construction General Permit. Silt fences, stabilized construction entrances, and inlet protection are standard temporary controls kept in place until the site is stabilized.
Failing to install or maintain required erosion controls on a permitted site draws TCEQ penalties and stop-work orders. Sediment leaving a recharge-zone site can contaminate the aquifer and compound liability.
