Permit authority, fine schedule, BMP requirements, and enforcement examples for commercial pressure washing in San Antonio. Your paper trail starts with a PAR.
Two penalty tracks stack simultaneously. Operating without documented BMPs exposes you to both.
| Enforcing Authority | Permit / Authority | Per-Violation Daily Fine | Notes |
|---|---|---|---|
| TCEQ / City of San Antonio Stormwater Services (SAWS) | TPDES TXR040000 / SAWS Stormwater Division | $25,000/day | State civil penalty; accrues daily until corrected and documented |
| U.S. EPA (CWA §309) | Clean Water Act §309 | $48,762–$56,460/day | Federal civil penalty floor; applies simultaneously with state penalties. 2025 CPI-adjusted. |
| Combined 30-day exposure | — | $750,000+ (state only) | One uncontained job, no PAR. 30 days × state daily penalty before settlement. |
Note: Municipal penalties may apply separately under local ordinances. Total exposure frequently exceeds state-level figures when federal and municipal tracks stack.
These are the documented steps that demonstrate compliance with TCEQ / City of San Antonio Stormwater Services (SAWS) requirements under TPDES TXR040000 / SAWS Stormwater Division. Each step is independently verifiable by an inspector — missing one is sufficient for a Notice of Violation.
SAWS Stormwater Division enforces illicit discharge prohibitions; Edwards Aquifer recharge zone violations face dual TCEQ and EPA enforcement exposure.
The San Antonio River / Edwards Aquifer watershed is actively monitored. Limestone stucco and terracotta — San Antonio sits directly over the Edwards Aquifer recharge zone. Caliche dust from limestone cutting + wash water reaching storm drains is a documented violation category. Spanish Colonial and Mission-style structures require low-pressure techniques to avoid mortar damage and runoff.
Enforcement risk in San Antonio is year-round — not seasonal. Inspectors respond to complaints, conduct dry-weather outfall inspections, and follow up on spill reports from adjacent property owners. The most common NOV trigger is visible runoff reaching a curb cut or storm drain inlet — something that can be photographed by a neighbor and reported within minutes of a wash job starting.
Every San Antonio job documented, signed, and delivered as a certified Pressure Washing Activity Record. Your paper trail in case TCEQ / City of San Antonio Stormwater Services (SAWS) comes calling.
Get Certified PAR — $99 →State penalties under TCEQ / City of San Antonio Stormwater Services (SAWS) (Permit TPDES TXR040000 / SAWS Stormwater Division) reach $25,000/day per violation per day. The EPA federal floor adds another $48,762–$56,460/day simultaneously under Clean Water Act §309. Both tracks accrue daily until the violation is corrected and documented.
You don't need a standalone permit as a contractor — but the property's MS4 permit (TPDES TXR040000 / SAWS Stormwater Division) governs all stormwater discharge on-site. If your wash water reaches the storm drain without containment and documentation, you and the property owner are both exposed. BMP compliance demonstrated by a PAR is your protection.
A PAR (Pressure Washing Activity Record) documents the chemicals used, surface type, water recovery method, and disposal pathway for each commercial wash job. In San Antonio, it serves as your contemporaneous paper trail demonstrating BMP compliance with TCEQ / City of San Antonio Stormwater Services (SAWS) requirements. Inspectors cannot challenge a properly completed PAR — it demonstrates intent and methodology, the two primary factors in settlement negotiations.
Pressure washing runoff in San Antonio drains to the San Antonio River → San Antonio Bay / Edwards Aquifer watershed. This system is actively monitored by TCEQ / City of San Antonio Stormwater Services (SAWS) under TPDES TXR040000 / SAWS Stormwater Division. Discharges that reach this waterway — even through intermediary storm drains — constitute a violation.
Core BMPs required by TCEQ / City of San Antonio Stormwater Services (SAWS): (1) pre-job site assessment with all storm drain inlets identified, (2) chemical log with SDS documentation, (3) water containment system deployed before washing begins, (4) pH testing of rinse water before disposal, (5) disposal to sanitary sewer only, (6) GPS-tagged pre/post photos, and (7) signed PAR filed for each job. Surface-specific note for San Antonio: Limestone stucco and terracotta — San Antonio sits directly over the Edwards Aquifer recharge zone. Caliche dust from limestone cutting + wash water reaching storm drains is a documented violation category. Spanish Colonial and Mission-style structures require low-pressure techniques to avoid mortar damage and runoff.
