Steps
Locate the exemption text at 30 TAC 330.13(f) via the Texas Secretary of State rules portal linked from TCEQ's Car Washes Compliance Resources page — it exempts drying of car wash grit trap waste from a waste permit.
Review TCEQ publication RG-389 ("Waste from Grease Traps, Grit Traps, and Septic Tanks: Questions and Answers") to confirm your handling process matches the exempted activity.
Check whether any of the waste also qualifies as used oil, which is instead governed by TCEQ's Used Oil Recycling Program and RG-325 guidance.
Verify your facility isn't separately triggering small-quantity-generator hazardous waste rules under RG-234 based on total waste volumes.
Retain documentation of your drying process and waste volumes on file in case of a TCEQ compliance inspection.
Known gotchas
The exemption is narrowly scoped to "drying" grit trap waste — wet storage, transport, or off-site disposal of grit trap waste can still trigger separate waste-permit requirements.
30 TAC 330.13(f) is hosted on the Texas Secretary of State's rules portal, a separate site from tceq.texas.gov — confirm you're viewing the current rule text, not an outdated copy.
