Summary
Any Texas construction that disturbs one acre or more must get TCEQ Construction General Permit (TXR150000) coverage and develop a Stormwater Pollution Prevention Plan with erosion and sediment controls before ground is broken.
Large construction activities which disturb 5 or more acres, or are part of a larger common plan of development or sale that will disturb 5 or more acres, are regulated under this general permit. Small construction activities which disturb at least 1 but less than 5 acres, or are part of a larger common plan of development or sale that will disturb at least 1 but less than 5 acres, are also regulated under this general permit.
Full Breakdown
TCEQ's TPDES Construction General Permit TXR150000 regulates stormwater from construction. Operators disturbing at least 1 but less than 5 acres (small construction) or 5 or more acres (large construction), including sites in a larger common plan of development, must obtain permit coverage. The permit requires developing and implementing a Stormwater Pollution Prevention Plan (SWP3) prior to commencing construction, using best management practices to control erosion and sediment in runoff. Large sites file a Notice of Intent through STEERS. The 2023 permit took effect March 5, 2023 and expires March 5, 2028.
Violations & Penalties
Discharging construction stormwater without CGP authorization violates Texas Water Code Chapter 26; TCEQ can assess administrative penalties, order corrective action, and pursue civil enforcement for uncontrolled erosion.
