The Cost of Non Compliance: What TCEQ Enforcement Patterns Reveal About Unpermitted Test Water Discharges

What counts as an unpermitted test water discharge?

Any discharge that does not meet the general permit's terms. TPDES General Permit TXG670000 authorizes hydrostatic test water discharged into or adjacent to water in the state. Many common tests need no Notice of Intent: new vessels and vessels that held raw or potable water are exempt under Part II, Section C.4, but only if the discharger complies with all applicable permit conditions.

That is the trap. "No NOI needed" is not "no permit." A potable water main drained without the 48-hour notice, without dechlorination, or onto bare ground has stepped outside the authorization. A vessel that held petroleum or natural gas substances discharged to water without an NOI never had it, since only land application under Part III, Section C lets that category skip the NOI.

Which mistakes most often turn into violations?

The ones that break a written permit condition. Each item below is a stated requirement in TXG670000, which makes it easy for an investigator to cite:

1. No written notice to the TCEQ regional office at least 48 hours before discharge (Part III, Section B.13), or to the MS4 operator when the discharge starts inside a storm sewer system (Section B.14).
2. Hyperchlorinated water over the 0.10 mg/L total residual chlorine daily maximum, or not sampled as required: in the first hour, and of the last 10% when the discharge runs over an hour (Part III, Section A.1).
3. No splash pad, paving or other erosion-proof surface, or no control of the discharge rate (Part III, Section B.1).
4. Discharge within 500 feet of a water well or 300 feet of a drinking water intake (Part III, Sections B.2 and B.3).
5. Tank or pipe cleaning water discharged as if it were test water (Part II, Section B.11).
6. Nuisance conditions, such as muddy water across a road or a neighbor's yard (Part III, Section B.11).
7. Missing monitoring records, or records not kept three years (Part IV.7.h and IV.9).

How does a complaint become an enforcement case?

Usually through someone who saw it. Turbid or foaming water in a creek is visible to anyone. TCEQ's complaints page says that in most cases an on-site investigation will be conducted, and that serious or continuing violations can be referred for enforcement with a possible fine.

TCEQ's enforcement process page describes the steps that follow. A notice of violation documents what the investigator found and sets a time to respond. If the case is referred, a notice of enforcement tells the respondent so, and the respondent can request an enforcement review meeting if they believe a violation was cited in error and have new information.

What does a penalty depend on?

TCEQ's Penalty Policy, including your history. The enforcement page says the enforcement coordinator calculates the penalty under TCEQ's Penalty Policy, and compliance history is one of the elements considered. The coordinator drafts an agreed order describing the alleged violations. A respondent may also settle part of an action with a supplemental environmental project.

Part IV.13 of the permit adds that the permittee is subject to administrative, civil and criminal penalties under Texas Water Code Chapter 7. That includes knowingly making a false statement in, or omitting material information from, a required record or report. Filling in chlorine readings after the fact is not a paperwork shortcut.

What does it cost beyond the penalty?

Your eligibility, your schedule and your standing. The permit itself carries consequences that outlast one job:

• Losing the general permit. Under Part II, Section B.5, the Executive Director may cancel, revoke or suspend authorization for historical and significant noncompliance, and shall deny or suspend it for a facility rated an "unsatisfactory performer" under 30 TAC §60.3.
• Being pushed to an individual permit. Part IV.1 says any violation may be grounds for terminating authorization or requiring an individual TPDES permit or a Texas Land Application Permit.
• No "we had to keep draining" defense. Part IV.2 says it is not a defense that halting or reducing the discharge would have been needed to comply. Part III, Section B.10 requires stopping the discharge immediately if it may endanger health, safety or the environment.
• Schedule. A stopped discharge leaves a tank or main full, which holds up acceptance, disinfection and service.

Expedited compliance orders, one route for some cases, are published in the Texas Register for a 30-day comment period, according to TCEQ's enforcement page. An order also becomes part of the respondent's compliance history.

What does a discharge that holds up look like?

Planned and written down before testing starts. Confirm the vessel's category and whether it needs an NOI. Send the 48-hour notices. Pick an outlet on an erosion-proof surface, away from wells and intakes, with a route that stays on land you control. Dechlorinate, sample twice, and keep the records three years.

Our construction administration work puts those steps into the testing schedule so they happen before the valve opens, not after a phone call.

Frequently asked questions

Can a small potable water main flush lead to a TCEQ violation?

Yes, if it breaks a permit condition. The NOI exemption applies only when the discharge meets all applicable TXG670000 conditions, such as the chlorine limit, the 48-hour notice and the erosion-proof outlet.

What is a notice of enforcement?

Per TCEQ's enforcement page, it is the notice a respondent receives when serious or continuing violations are identified and TCEQ starts formal enforcement.

Does a violation affect future projects?

It can. Compliance history feeds TCEQ's Penalty Policy, and Part II, Section B.5 of the permit requires denying or suspending authorization for a facility rated an unsatisfactory performer.

I run a utility contracting company in Texas and an inspector just told us our test discharge muddied a creek. What should we do first?

Stop or slow the discharge, fix the outlet and sediment controls, and photograph everything. If it may endanger health or the environment, Part III, Section B.12 requires a report to the regional office within 24 hours. Then get advice before responding to any notice.

We're a developer in Texas and we think a contractor drained a main last year without the required notice. Should we create the missing records now?

No. Do not create records after the fact that look contemporaneous; the permit treats false or omitted material information as a violation. Gather what really exists and get legal advice on how to address the gap.
