Stormwater Pollution Prevention Plan (SWP3) guidance document

This Stormwater Pollution Prevention Plan (SWP3) Guidance Manual provides guidelines for completing the SWP3 Summary Sheets and SWP3 Binder documentation necessary for complying with the Texas Pollutant Discharge Elimination System Construction General Permit TXR150000 (CGP) administered by the Texas Commission on Environmental Quality. Projects that let beginning in March 2023 must follow the templates outlined in this guidance manual. Projects that let before March 2023 may use other templates but must still contain all the required information in the March 5, 2023, reissuance of the CGP.

The SWP3 provides a strategy to prevent or minimize sediment and other pollutants originating from construction sites from reaching surface waters of the state during those construction activities. Pollutants can enter waters of the state through direct discharges to water bodies or municipal separate storm sewer systems or can be carried in stormwater as it flows over a construction site. The SWP3 outlines erosion control, sediment control and behavioural best management practices to control those pollutants.

You might note that projects with less than one acre of soil disturbing activities do not require authorization under the CGP. However, internal TxDOT Environmental Management System (EMS) policy requires the implementation of environmental controls to meet our internal standards, in addition to meeting other requirements that result from the environmental review process. Therefore, TxDOT requires the development of SWP3s for all projects with soil disturbance and guidance is included in this manual. However, there is an important distinction for Local Government Let Projects as these projects will instead follow guidance in the Local Government Projects Policy Manual Chapter 5 that can be found in the Local Government Toolkit.

The SWP3 Summary Sheets must be completed by the TxDOT design engineers or TxDOT’s consultants during the design phase of the project. The SWP3 Summary Sheets outline project details with respect to the proposed construction activities and with the potential to generate pollutants. The SWP3 Summary Sheets also outline selected BMPs to manage stormwater runoff from the construction site. The SWP3 Summary Sheets are to be included as plan sheets in TxDOT’s construction drawings for the project.

The SWP3 Binder is used by TxDOT personnel during construction to store the required SWP3 contents in accordance with the CGP. It includes copies of the complete SWP3 Summary Sheets and required appendices. TxDOT personnel must complete, use and maintain a current SWP3 Binder, including the SWP3 Summary Sheets during construction activities. The SWP3 Binder may exist as a physical paper document or may be electronically filed. No matter what format it’s in, it must contain all the information as outlined in this Manual.

The SWP3 Summary Sheets and Binder are considered “living documents” and must be maintained and updated throughout the life of the project until construction is completed, and final stabilization has been achieved.
