TCEQ Seeks Input on Public Water System Monitoring Plans

The Texas Commission on Environmental Quality (TCEQ) is seeking feedback on draft revisions to RG-384, “How to Develop a Monitoring Plan for a Public Water System.” Cities that wish to submit feedback on the draft monitoring plan should do so by September 15, 2017.  This is not a formal rulemaking, so TCEQ has prepared an excel spreadsheet form for submitting comments by email to

What is a monitoring plan? The plan is required for all public water systems.  It is a system-specific document demonstrating compliance with regulatory requirements and that water quality monitoring is representative of the water distributed to consumers.

Systems that treat surface water or groundwater under the direct influence of surface water are required to send a copy of their monitoring plan to the TCEQ for review and approval. A copy of the plan should also be kept at each treatment plant, as well as at city hall. Systems that use groundwater or purchased water are not required to send a copy of the monitoring plan to TCEQ.

Instead, those systems must keep the plan on file for review by the TCEQ inspector during routine comprehensive compliance investigations, or must provide a copy of the plan to TCEQ upon request. A copy of the plan should be kept at each treatment plant, as well as at city hall.

Additionally, all public water systems are required to have a copy of the monitoring plan available during appointments with the TCEQ's sample collection contractor. Additional information about monitoring plans is posted on the TCEQ website
